Billy finished his history assignment in 1/4 hours. Then he completed he’s chemistry assignment in 1/3 hours. What’s the total amount of time bill spent doing these 2 assignments

Answer:

12.6

Step-by-step explanation:

10.08/.8 = 12.6, dividing the amount of time by the amount of time to make a skirt to get the number of skirts she can make

The expression factoring out the greatest common factor is  (3pf - 21p²)(f + 2).

We have the expression as

3pf² - 21p²f + 6pf - 42p²

Now, factorising the expression as

= 3pf² + 6pf - 21p²f - 42p²

= 3pf(f +2) - 21p²(f + 2)

= (3pf - 21p²)(f +2)

Answer:

proportional reasoning involved thinking about relationship and making comparisons of countries are values in the words of John went Diwali portion reasoning is difficulty find it is not something that you can or not to but is diploma over 3 reasoning

Observe the quantities, ie. see what happens if you increase one or decrease the other.

To simplify imagination, expose one quantity. I will expose y.

1.

\(-\frac{y}{4}=2x\implies y=-8x\)

So what is their variation or proportion? If I increase x then y is getting more and more negative. So is this direct or inverse or nothing? It is direct.

2.

\(14x=\frac{14}{y}\implies y=x, y\neq0\) again if I increase x then y will match, will also increase. This is again direct.

3.

\(y=\frac{13}{x}, x\neq0\) this time if I increase x, y will get smaller. When x is exactly 13, y will be 1 and when x is 10000, y will be 0.0013. This is inverse. One quantity gets really small when other quantity gets really big.

4.

\(y=x-2\) if I increase x then y will also increase even though by slightly less (-2) it will still increase. However since there is no multiplication this is not a direct variation nor is it inverse. It is nothing/no-variation.

Hope this helps :)

Therefore, the volume of the cone is 1128.88 cubic centimeter.

The slope of the line passing through points: (2,4) and (1,3) is 1

By definition, the slope or gradient of a line describes its steepness, incline, or grade. To calculate the slope of the line passing through the points we use the below formula,

\(m=\frac{Y_{2}-Y_{1} }{X_{2} -X_{1} }\)

\(Here ~Y_{2} = 3, Y_{1} =4 , X_{2}=1 ~ and~ X_{1} =2.\)

\(Hence, m=\frac{3-4}{2-1} =\frac{-1}{-1} \\~~~~~~~~~~~ m= 1.\)

In mathematics, a slope is a number that quantifies the steepness and direction of a line, or a portion of a line connecting two points and is commonly symbolized by m. In general, the absolute magnitude of a line's slope, m, is used to determine its steepness. The steeper the line, the greater the value. Based on the sign and value of m, it is feasible to establish the direction of the line that m describes.

The slope is defined as the change in height divided by the change in horizontal distance, and it is also known as "rise over run." It has applications in both geography and civil engineering, such as road construction. In the case of a road, the "rise" is the change in height, while the "run" is the difference in distance between two fixed places, as long as the distance for measurement is not so great that the earth's curvature is taken into account.

Hence slope of the line passing through points: (2,4) and (1,3) is 1

The area or region that an object’s surface occupies is known as its surface area. Volume, on the other hand, refers to how much room an object has. There are numerous shapes and dimensions in geometry, including spheres, cubes, cuboids, cones, cylinders, etc. Each form has its own volume and surface area.

Given, the measures of the box are 11 * 2 *4 cm.

We need to find out how much wrapping paper would be required. to achieve that we need to calculate the surface area of the box.

From the general formula of the surface area of a cuboid.

Surface area = 2*(length*width + width * height + width * height)

in our case,

length = 11

width = 2

and height = 4

Thus,

Surface area = 2 (11*2 + 2*4 + 11*4)

Surface area = 2(22 + 8 + 44)

Surface area = 148 cm²

Answer:

x = 6

Step-by-step explanation:

This is a bit of a tricky equation, and it's what we call an exponential equation since it involves some exponents. The way we begin to solve these kinds of problems is make the base on each side of the equals sign the same. On one side, we have 9 as our base, and on the other side, we have 3 as our base. 9 = 3², so we can rewrite our equation as shown below:

(3²)⁴ˣ⁻¹⁰ = 3⁵ˣ⁻²

From there, we can use the exponent rule (xᵃ)ᵇ = xᵃᵇ to simplify the left side of the equation.

3²⁽⁴ˣ⁻¹⁰⁾ = 3⁵ˣ⁻²

3⁸ˣ⁻²⁰ = 3⁵ˣ⁻²

Since our bases are now the same, we can take just the exponents and turn it into a new equation as shown below:

8x - 20 = 5x - 2

Hopefully at this point, this problem becomes easy for you, but I'll show how I solved this new equation below in case it doesn't make sense.

8x - 20 = 5x - 2

8x - 20 - 5x = 5x - 2 - 5x

3x - 20 = -2

3x - 20 + 20 = -2 + 20

3x = 18

3x/3 = 18/3

x = 6

The triangle ABC seems to be an scalene triangle since all of the sides AB, BC and CA have different lengths, and also the triangle is not a right angled triangle.

A scalene triangle is a type of triangle in which all three sides have different lengths. In other words, none of its sides are of equal length. As a result, all three angles in a scalene triangle are also different. It is different from an Isosceles triangle, where at least two sides are of equal length and an equilateral triangle where all sides are of equal length.

A right triangle is a type of triangle in which one angle is a right angle (90 degrees). This makes it different from other types of triangles such as acute triangle and obtuse triangle. The side opposite to the right angle is called the hypotenuse, and the other two sides are called legs. The Pythagorean theorem states that in a right triangle, the sum of the squares of the lengths of the legs is equal to the square of the length of the hypotenuse. This theorem is used to determine if a triangle is a right triangle or not.

The triangle ABC is a scalene triangle, as its sides have different lengths.

To determine whether it is a right triangle, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the lengths of the two shorter sides (legs) is equal to the square of the length of the longest side (hypotenuse).

To find the side lengths, we can use the distance formula, which is

d = √((x2 - x1)² + (y2 - y1)²)

AB = √((9 - 6)² + (3 - 6)²) = √(3² + (-3)²) = √18 = 3√2

BC = √((9 - 2)² + (3 - 2)²) = √(7² + 1²) = √50 = 5√2

AC = √((2 - 6)² + (2 - 6)²) = √(4² + 4²) = √32 = 4√2

We know that in a right triangle, one of the side should be the hypotenuse and the other two should be the legs. We can check if any one of the side is satisfying that. But in this case, we can see that none of the sides are satisfying that condition, therefore the triangle ABC is not a right triangle.

Answer:

Therefore, the correct statements are A, B, and E.

Explanation:

Based on my knowledge, a vector is a quantity that has both magnitude and direction. A scalar is a quantity that has only magnitude. When a vector is multiplied by a scalar, the magnitude of the vector is multiplied by the absolute value of the scalar, and the direction of the vector is either preserved or reversed depending on the sign of the scalar.

To answer your question, we need to find the component form, magnitude, and direction of the scalar product –4⇀

.

- The component form of −4⇀

is obtained by multiplying each component of ⇀

by –4. Therefore, −4⇀

= ⟨–8, –12⟩. This means that statement A is true.

- The magnitude of −4⇀

is obtained by multiplying the magnitude of ⇀

by 4. The magnitude of ⇀

is √(2^2 + 3^2) = √13. Therefore, the magnitude of −4⇀

is 4√13. This means that statement B is true.

- The direction of −4⇀

is opposite to the direction of ⇀

because the scalar –4 is negative. This means that statement C is false.

- The vector −4⇀

is in the third quadrant because its components are both negative. This means that statement D is false.

- The direction of −4⇀

is 180° greater than the inverse tangent of its components because it is opposite to ⇀

. The inverse tangent of its components is tan^(-1)(–12/–8) = tan^(-1)(3/2). Therefore, the direction of −4⇀

is 180° + tan^(-1)(3/2). This means that statement E is true.

Therefore, the correct statements are A, B, and E.

To paint the outside of one basket, George will require 1190 square cm of paint, considering the dimensions of the cuboid as length: 17 cm, breadth: 17 cm, and height: 9 cm.

To calculate the amount of paint needed to cover the outside of one basket, we need to determine the total surface area of the cuboid.

The cuboid has a length of 17 cm, a breadth of 17 cm, and a height of 9 cm. Since the basket is open from the top, we only need to paint the sides.

The surface area of a cuboid is given by the formula:

Surface Area = 2(length * breadth + length * height + breadth * height)

Plugging in the values:

Surface Area = 2(17 * 17 + 17 * 9 + 17 * 9)

Simplifying the equation:

Surface Area = 2(289 + 153 + 153)

Surface Area = 2(595)

Surface Area = 1190 square cm

Answer: f(x) has an axis of symmetry at x = 4 and h(x) has an axis of symmetry at x = -2

Step-by-step explanation:

You can easily find the axis of symmetry by investigating around which line the functions are symmetrical about

for instance, in h(x), the graph is symmetrical on either side of x = -2, meaning that the line x = -2 cuts the parabola in 'half'

in f(x), this is a little harder to think about, but if you know how the graph will be shifted on the x-axis you can figure it out! In this case (x-4)^2 means that the graph will be shifted on the x-axis 4 units to the right (or from the origin to +4 on the X axis)

as such the line x = 4 will cut the function f(x) in 'half'

A = 11.4 months

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of months be represented as = A

Now , the equation is

Now , the total amount with Mark = $ 146.43

The initial amount for the smartphone = $ 33

The amount per month for 2GB is = $ 9.95

So , the amount for A months = $ 9.95 ( A )

So , the equation will be

Initial amount for the smartphone + the amount for A months = total amount with Mark

Substituting the values in the equation , we get

33 + 9.95 ( A ) = 146.43   be equation (1)

On simplifying the equation , we get

Subtracting 33 on both sides of the equation , we get

9.95 ( A ) = 113.43

Divide by 9.95 on both sides of the equation , we get

A = 11.4 months

Therefore , the value of A is 11.4 months

To calculate your bi-weekly paycheck, follow these steps:

Step 1: Calculate the gross earnings:

Multiply the number of hours worked per week by the hourly rate.

20 hours/week * $9.00/hour = $180.00/week

Step 2: Calculate the total earnings for two weeks:

Multiply the weekly earnings by the number of weeks in a bi-weekly pay period.

$180.00/week * 2 weeks = $360.00

Step 3: Calculate the deductions:

Calculate each deduction separately and subtract them from the gross earnings.

Federal Income Tax: $360.00 * 11.9% = $42.84

State Income Tax: $360.00 * 3.6% = $12.96

F.I.C.A: $360.00 * 7.65% = $27.54

Professional Dues: Amount varies depending on the specific dues.

Total Deductions: $42.84 + $12.96 + $27.54 + Professional Dues

Step 4: Calculate the net earnings:

Subtract the total deductions from the gross earnings.

Net Earnings = Gross Earnings - Total Deductions

Once you have the net earnings, you can determine if it is sufficient to cover your monthly car insurance bill of $200. If your bi-weekly net earnings are greater than or equal to $200, you will be able to pay your car insurance bill.
