What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Edna bought a cube-shaped jewelry box that has 7-inch sides.

And, The volume of a cube with side s is s³.

Now,

Since, Edna bought a cube-shaped jewelry box that has 7-inch sides.

Hence, The volume of the jewelry box = 7³

                                                            = 7 × 7 × 7

                                                            = 343 inch³

Answer:

Step-by-step explanation:

We can solve this question by applying the Pythagorean theorem to the triangle (a^2+b^2=c^2). The Pythagorean theorem states that if the two shorter lengths are both squared and added the sum of those two numbers should be equal to the longest side squared. So 6 and 8 are the shorter sides of this triangle so we can plug either one in for either a or b, 6^2+8^2=9^2. Once you do that you have to square each individual number. You should get 36+64=81

36+64 is 100 and 100 does not equal 81 therefore this triangle is not a right triangle.

Answer:

Step-by-step explanation:

If a² + b² > c² , the triangle is acute,  

If a² + b² = c² , the triangle is a right triangle,

If a² + b² > c² , the triangle is obtuse,  

where "a" and "b" are the lengths of the 2 shorter sides of the triangle and "c" is the length of the longest side.

~~~~~~~~~~~~~

6² + 8² > 9² ⇒ given triangle is acute

The equation for the regression line from the data is y = -0.98x + 56.8

Given data ,

To find the equation of the regression line, we will use the method of least squares. The regression line is represented by the equation:

y = mx + b

where m is the slope of the line and b is the y-intercept.

We need to calculate the values of m and b. Let's begin by finding the mean values of x and y:

Mean of x (x₁) = (6 + 13 + 14 + 10 + 13) / 5 = 12.2

Mean of y (y₁) = (25 + 44 + 46 + 52 + 57) / 5 = 44.8

Next, we calculate the deviations from the mean for both x and y:

Deviation from the mean of x (Δx) = x - x₁

Deviation from the mean of y (Δy) = y - y₁

Now, we calculate the sum of the products of the deviations from the mean:

Σ(Δx * Δy) = (6 - 12.2) * (25 - 44.8) + (13 - 12.2) * (44 - 44.8) + (14 - 12.2) * (46 - 44.8) + (10 - 12.2) * (52 - 44.8) + (13 - 12.2) * (57 - 44.8)

Σ(Δx * Δy) ≈ -51.6

Next, we calculate the sum of the squared deviations from the mean of x:

Σ(Δx²) = (6 - 12.2)² + (13 - 12.2)² + (14 - 12.2)² + (10 - 12.2)² + (13 - 12.2)²

Σ(Δx²) ≈ 52.8

Now, we can calculate the slope (m) using the formula:

m = Σ(Δx * Δy) / Σ(Δx²)

m ≈ -51.6 / 52.8 ≈ -0.98

Finally, we can calculate the y-intercept (b) using the formula:

b = y₁ - m * x₁

b ≈ 44.8 - (-0.98) * 12.2 ≈ 56.8

Hence , the equation of the regression line for the given data is:

y = -0.98x + 56.8

To evaluate the quotient 513÷19 using the area model:

• The first thing Stefon did is to pick an easy multiple (x 10) of 19.

• Next, the result is subtracted from 513 to get 323.

• This is repeated to get a remainder, 133.

• Since 133 is less than (10 x 19 =190), Stephon then used a lower multiple of 19, which is 7.

• He subtracted the result and got a remainder of 0.

The angle ∠R, ∠S, and ∠T for the quadrilateral are ∠R, ∠S, ∠T = 112°, 112°, 68°.

what are quadrilaterals?

A quadrilateral is a polygon with four sides, four vertices, and four angles.

It is formed by joining four non-collinear points. The sum of the interior angles of quadrilaterals is always equal to 360 degrees. The word quadrilateral is derived from the Latin words ‘Quadra’ which means four and ‘Latus’ means ‘sides’. Not all the four sides of a quadrilateral need to be equal in length. Hence, we can have different types of quadrilaterals based on sides and angles.

Five special quadrilaterals are shown below in the image, along with their definitions and pictures, and points for them to get proven.

Now,

TQRS is an inscribed quadrilateral.

5 x - 52° + 3 x + 40° = 180°

8 x - 12° = 180°

8 x = 180° + 12°

8 x = 192°

x = 192° : 8 = 24°

m∠ R = 3 · 24° + 40° = 112°

m∠ T = 5 · 24° - 52° = 68°

m∠ S = 360° - ( 68° + 68° + 112° ) = 112°

Answer:

either 22/60 or .3666 recurring

Step-by-step explanation:

All you are doing is converting minutes to hours basically, so all you have to do is divide 22 by 60.

To reach her home in half an hour, she needs to double her speed twice, which is equivalent to a 200% increase in speed. Therefore, the correct answer is 200%.

Speed is a measure of how quickly an object or person moves from one point to another. It is usually expressed in terms of distance traveled over time, for example, miles per hour or kilometers per hour.

To calculate this, we need to find the time taken for her to reach her home if her speed is doubled.

If her initial speed is 40 km/hr, then by doubling her speed, she will be travelling at a speed of 80 km/hr.

By travelling at this speed, she can reach her home in half an hour i.e. 30 minutes.

Therefore, the time taken to reach her destination by doubling her speed is 30 minutes.

The time taken to reach her destination while travelling at her initial speed is 2 hours.

To calculate the percentage increase in speed, we have to find the ratio of the time taken to reach her destination when the speed is doubled to the time taken to reach her destination when the speed is not doubled.

Therefore, the percentage increase in speed

= (30/120) x 100

= 25%.

Since she needs to double her speed to reach her home in half an hour, the percentage increase in speed required is 100%.

To reach her home in half an hour, she needs to double her speed twice, which is equivalent to a 200% increase in speed.

Therefore, the correct answer is 200%.

The length of the hypotenuse is 12.52 yards.

Given that a right triangle, we need to find the value of the hypotenuse x,

Trigonometric ratios can be calculated by taking the ratio of any two sides of the right-angled triangle.

We can evaluate the third side using the Pythagoras theorem, given the measure of the other two sides. We can use the abbreviated form of trigonometric ratios to compare the length of any two sides with the angle in the base.

Let us consider a right-angled triangle with one of its acute angles to be x. Then the cosine formula is, cos x = (adjacent side) / (hypotenuse), where "adjacent side" is the side adjacent to the angle x, and "hypotenuse" is the longest side (the side opposite to the right angle) of the triangle.

We know that, the cosine of the angle is the ratio of the base to the hypotenuse,

So,

Cos 37° = 10 / x

x = 10 / Cos 37°

x = 12.52

Hence the length of the hypotenuse is 12.52 yards.

and so we also see, that the function calculates the % of the remaining carbon-14.

so, we need the desired outcome 60(%),

because 60 = 100 - 40.

45, 45 and 90 degrees

Step-by-step explanation:

Complete question

The measures of angles X and Y are the same, x degrees. The measure of angle Z is twice the measure of angle Y. Find the measure of each angle

Let the sum of the angles be 180 degrees

X = x

Y = x

If Z is twice the measure of angle Y, then;

Z = 2x

Taking the sum

<X + <Y + <Z = 180

x+x+2x = 180

4x = 180

x = 180/4

x = 45

since Z = 2z

Z = 2*45

Z = 90

Hence the measure of the angles X, Y and Z are 45, 45 and 90 respectively

Asymmetric: Since, for instance, (2,3) is in R but (3,2) is not, R is not asymmetric. No element in A is connected to itself under R, making R irreflexive.

The collection of output values that such a function of relation can produce is referred to as the range in mathematics. It is the distinction between the largest or smallest values within an ensemble of data or a collection of all conceivable function or relation output values.

In other terms, it is the range of possible values for a variable. For instance, the range is 21 - 3 = 18 if the integers are 3, 7, 12, 15, and 21. The set of all value of y which may be produced by a function f(x) for the given subject area of x values is known as the range.

given

We will now examine the many characteristics of the relation R:

As no element in A is connected to itself under R, R is not reflexive. For instance, R does not support (2,2).

R is not symmetric since, for instance, (3,2) is not in R yet (2,3) is.

R is transitive because, for instance, the existence of (2,3) and (3,5) in R entails the existence of (2,5) in R.

Equivalence: As R is not reflexive or symmetric, it is not an equivalence relation.

Asymmetric: Since, for instance, (2,3) is in R but (3,2) is not, R is not asymmetric. No element in A is connected to itself under R, making R irreflexive.
