Answer:
8
Step-by-step explanation:
Using the Heron's formula we can find that the total area of the triangle is 84 inches.
Then, to find the height of the triangle, you have to multiply the area by 2 since the formula for the area of a triangle is (h*b)/2
Now, when we multiply 84 and 2 we get 168, so you have to divide 168 by 21 to find 8.

\(\begin{gathered} f(1)=16=5(1)+b \\ \text{hence } \\ 16=5(1)+b \\ 16=5+b \\ b=16-5 \\ b=11 \end{gathered}\)Hence, the answer is b = 11
Farmer Bob has pigs and chickens. He has 37 animals, and there are 124 legs among them altogether. How
many chickens does Bob have?
Answers
x + y = 37; 4x + 2y = 124
To save time, the answer to this system of equations is x = 25, and y = 12. Because pigs have four legs, this means there are 25 pigs (as represented in the system of equations) and there are 12 chickens because they each have two legs.
Your final answer: There are 25 pigs and 12 chickens.
Step-by-Step Explanation:
Let ‘x’ be the No. Of Chickens
Let ‘y’ be the No. Of Pigs
Total = 37 Animals
Total No. of Legs = 124
We know, a Chicken has 2 legs and a Pig has 4 legs.
Framing the Equations :-
=> x + y = 37 (Eq. 1)
=> 2x + 4y = 124 (Eq. 2)
Therefore, from Eq. 1 :-
x + y = 37
=> x = 37 - y (Eq. 3)
Substitute value of ‘x’ from Eq. 3 in 2 :-
2x + 4y = 124
2(37 - y) + 4y = 124
74 - 2y + 4y = 124
74 + 2y = 124
2y = 124 - 74
2y = 50
y = 50/2
=> y = 25
Substitute value of ‘y’ in Eq. 3 :-
x = 37 - y
x = 37 - (25)
=> x = 12
Therefore,
No. Of Chickens = 12
No. Of Pigs = 25

Answers
Multiplying ampere (amp) by ohm gives units of volt (V).
Therefore, the answer will be in volts (V). This is because ohm is the unit of electrical resistance, ampere is the unit of electrical current, and volt is the unit of electrical potential difference, which is calculated as the product of current and resistance according to Ohm's law: V = I × R.
Ohm is the unit of electrical resistance, which measures how much a material opposes the flow of electric current. One ohm (1 Ω) of resistance is defined as the amount of resistance that allows one ampere (1 A) of current to flow when a potential difference of one volt (1 V) is applied across it.
Ampere is the unit of electrical current, which measures the rate at which electric charge flows through a material. One ampere (1 A) of current is defined as the flow of one coulomb of electric charge per second.
Volt is the unit of electrical potential difference, which measures the amount of energy required to move a unit of electric charge from one point to another. One volt (1 V) of potential difference is defined as the amount of energy required to move one coulomb of electric charge across a circuit element that has one ohm of resistance.

Answers
Answer:
123
Step-by-step explanation:
\(180 - 57 = 123\)
The solution is, the value of m∠6 is 123, i.e. A- 123 °.
What is an angle?In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.
We know that, a ray is a line that continues on forever inn one direction with a point at it's start.
here, we have,
from the given figure we get,
angle 1 is equal to angle 5
as they are corresponding angles,
so, m∠1 =57° = m∠5
now, we have,
that the sum of 5 & 6 is 180
so, they are supplementary angles.
i.e. m∠6 = 180 - m∠5
=180 - 57
=123
Hence, The solution is, the value of m∠6 is 123, i.e. A- 123 °.

I bought 2 books. One cost twice as much as the other. Together they cost £3.45.
How much did the dearer book cost?
Answers
We can express this as:
x + 2x = £3.45
We can solve for x with no additional work.
x + 2x = £3.45
3x = £3.45
3x/3 = £3.45/3
x = £1.15
Im guessing you're British by the use of the £ symbol, and I don't understand what "dearer" means as in America we don't use that term. I'll just give you both values.
x = £1.15 (this is the first book)

7. Use the Composite Trapezoidal rule with the indicated values of \( n \) to approximate the following integrals. (1 mark) (a) \( \int_{1}^{2} x \ln x d x, \quad n=4 \) (b) \( \int_{2}^{2} x^{3} e^{x
Answers
The Composite Trapezoidal rule is used to approximate the given integrals. In part (a), the integral \(\( \int_{1}^{2} x \ln x \, dx \)\) is approximated using \(\( n = 4 \)\)subintervals. In part (b), the integral\(\( \int_{2}^{2} x^{3} e^{x} \, dx \)\) is given with incorrect limits, so it cannot be evaluated.
To approximate \(\( \int_{1}^{2} x \ln x \, dx \)\) using the Composite Trapezoidal rule, we divide the interval \(\([1, 2]\) into \( n = 4 \)\) subintervals. The step size, \(\( h \)\), is calculated as\(\( h = \frac{b-a}{n} = \frac{2-1}{4} = \frac{1}{4} \)\). Then, we evaluate the function \(\( x \ln x \)\)at the endpoints of each subinterval and sum the areas of the trapezoids formed. The approximation formula for the Composite Trapezoidal rule is: \(\[\int_{a}^{b} f(x) \, dx \approx \frac{h}{2} \left[ f(a) + 2\sum_{i=1}^{n-1} f(x_i) + f(b) \right]\]\)
Using this formula, we can calculate the approximation for the given integral. The limits of the integral \(\( \int_{2}^{2} x^{3} e^{x} \, dx \)\) are given as \(\( 2 \)\) to 2 which indicates an interval of zero length. In this case, the integral cannot be evaluated since there is no interval over which to integrate.

Choose the system of equations which matches the following graph.
A. 3x-6y=12
9x-18y=36
B. 3x+6y=12
9x+18y=36
Answers
The system of equations that matches the given graph is:
A. 3x - 6y = 12
9x - 18y = 36
To determine which system of equations matches a given graph, we need to analyze the slope and intercepts of the lines in the graph.
Looking at the options provided:
A. 3x - 6y = 12
9x - 18y = 36
B. 3x + 6y = 12
9x + 18y = 36
Let's analyze the equations in each option:
For option A:
The first equation, 3x - 6y = 12, can be rearranged to slope-intercept form: y = (1/2)x - 2.
The second equation, 9x - 18y = 36, can be simplified to 3x - 6y = 12, which is the same as the first equation.
In option A, both equations represent the same line, as they are equivalent. Therefore, option A does not match the given graph.
For option B:
The first equation, 3x + 6y = 12, can be rearranged to slope-intercept form: y = (-1/2)x + 2.
The second equation, 9x + 18y = 36, can be simplified to 3x + 6y = 12, which is the same as the first equation.
In option B, both equations also represent the same line, as they are equivalent. Therefore, option B does not match the given graph.

5

Answers
The mean of the distribution of sample means would be 27 hours, which is the same as the average life of the candles.
This is because the sample means would be expected to be centered around the population mean.
The standard deviation of the distribution of sample means (also known as the standard error of the mean) can be calculated using the formula:
standard deviation of sample means = standard deviation of population / square root of sample size
In this case, the standard deviation of sample means would be:
6 / square root of 4 = 3
So the answer is 3.
So, the mean of the distribution of the sample means would be 3. Your answer: 3.

A florist buys a dozen roses for $12.96 and sells them for $48.48. Find the amount of markup on a single rose.
Answers
The amount of markup on a single rose is $2.74.
What is markup formula?The markup formula is defined as the profit per unit cost of an item and is given as,
Markup = 100 * profit/cost
We multiply by 100 because we express it as a percentage, not as a fraction.
Now it is given that,
Cost Price of a dozen roses = $2.96
Number of roses = 12
Thus, Cost Price of 1 rose = 12.96/12 = $.108
Now it is also given that, the these dozen roses are sold at $48.48
So, Selling price of 1 rose = 48.48/12 = $4.04
Thus, Profit = Selling Price - Cost Price
⇒ Profit = $4.04 - $1.08
⇒ Profit = $2.96
Thus,Amount of Markup of single rose = Profit/Cost of 1 rose
⇒ Amount of Markup of single rose = 2.96/1.08
⇒ Amount of Markup of single rose = 2.74
Thus, the amount of markup on a single rose is $2.74.

Find dy/dx if x3y are related by 2xy +x=y4
Answers
The derivative dy/dx when x^3 and y are related by the equation 2xy + x = y^4 is dy/dx = (-2y - 1) / (2xy - 4y^3)
To find dy/dx when x^3 and y are related by the equation 2xy + x = y^4, we need to differentiate both sides of the equation implicitly with respect to x.
Differentiating both sides with respect to x:
d/dx [2xy + x] = d/dx [y^4]
Using the product rule for differentiation on the left side:
(2y + 2xy') + 1 = 4y^3 * dy/dx
Simplifying the equation:
2y + 2xy' + 1 = 4y^3 * dy/dx
Now, let's isolate dy/dx by moving the terms involving y' to one side:
2xy' - 4y^3 * dy/dx = -2y - 1
Factoring out dy/dx:
dy/dx (2xy - 4y^3) = -2y - 1
Dividing both sides by (2xy - 4y^3):
dy/dx = (-2y - 1) / (2xy - 4y^3)
Therefore, the derivative dy/dx when x^3 and y are related by the equation 2xy + x = y^4 is given by:
dy/dx = (-2y - 1) / (2xy - 4y^3)
