The length of the sides (8in, 15 in, z) into the Pythagorean Theorem. Then, find the length of the missing side z.

z = 17

This is further explained below.

Generally, In the field of mathematics, the Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic connection in Euclidean geometry among three sides of a right triangle.

Pythagoras is credited with developing this theorem. It indicates that the total of the areas of the squares on the other two sides is equal to the area of the square whose side is the hypotenuse.

This signifies that the size of the square whose side is the hypotenuse is equal to that amount.

In conclusion,

a² + b² = c²

8² + 15² = z²

64 + 225 = 289

z² = 289

Corresponding parts of congruent triangles are congruent.

What do you mean by congruency?

In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other. Formally speaking, two sets of points are said to be congruent if—and only if—they can be changed into one another by an isometry, which is a combination of rigid movements like translation, rotation, and reflection. This indicates that one item may be exactly aligned with the other object by moving and reflecting it, but not by resizing it. So if we can cut out and then perfectly match up two separate plane figures on a sheet of paper, they are congruent. The paper may be turned over.

a. The rate of change in length of baby grace is 0.75.

b. The linear equation for Baby Grace growth rate in point slope form is y - 20 = 0.75(x - 4)

a. The slope of the line for baby Claire growth is 0.8.

b. Baby girl Claire growth rate is faster than baby girl Grace growth rate.

Let's solve for the growth chart of baby grace.

Therefore,

a.

The rate of change in length of baby Grace can be found as follows:

rate of change = y₂ - y₁ / x₂ - x₁

Hence, using (4, 20)(6, 21.5)

rate of change = 21.5 - 20 / 6 - 4

rate of change = 1.5 / 2

rate of change = 0.75

b . The linear equation in point slope form can be found as follows;

y - y₁ = m (x - x₁)

where

Therefore,

y - 20 = 0.75(x - 4)

Let's tackle the growth chart for baby Claire,

a.

slope of the line = y₂ - y₁ / x₂ - x₁

Using (4, 22)(14, 30)

slope of the line = 30 - 22 / 14 - 4

slope of the line = 8 / 10

slope of the line = 4 / 5 = 0.8

b.

Therefore, Baby Claire growth rate is faster than baby Grace.

This is because bay Claire growth rate is 0.8 and baby Grace is 0.75.

Start by setting it up with the divisor 33 on the left side and the dividend 94 on the right side.

The divisor 33 goes into the first digit of the dividend 9, 0 time(s). Therefore, put 0 on top.

Multiply the divisor by the result in the previous step (33 x 0 = 0) and write that answer below the dividend.

Subtract the result in the previous step from the first digit of the dividend (9 - 0 = 9) and write the answer below.

Move down the 2nd digit of the dividend 4

The divisor 33 goes into the bottom number 94, 2 time(s). Therefore, put 2 on top.

Multiply the divisor by the result in the previous step (33 x 2 = 66) and write that answer at the bottom.

Subtract the result in the previous step from the number written above it. (94 - 66 = 28) and write the answer at the bottom.

The time taken to complete 5 questions is (option b) 22 minutes, 30 seconds

Given,

The number of questions = 2

Time taken to complete 2 questions = 9 minutes

Now,

The number of questions = 5

We have to find the time taken to complete 5 questions:

We can consider ratio here:

That is,

Number of questions : Time taken to complete

So,

2 : 9 and 5 : x

Lets equate:

2 : 9 = 5 : x

That is,

2x = 5 × 9

Now, divide 2 on both sides:

2x/2 = (5 × 9) / 2

Here,

x = 45/2

Then,

x = 22.5

Converting this into minutes, we get 22 minutes, 30 seconds.

THE GCF IN THE EXPRESSION IS 5 MEANING WE ARE GOING TO DIVIDE EACH AND EVERY TERM BY 5 .

[tex] = 5(3w + 13)[/tex]

ATTACHED IS THE SOLUTION

Answer: 72 degrees

Step-by-step explanation: We know that angle DHG and angle EHF are congruent due to the vertical angles theorem. Since these two angle measures are congruent, this also means that the expression 6(x-2) is congruent to 3x+30. To find the angle measure of DHG, we need to find x. We can set these two expressions equal to each other and solve for x.

6(x-2) = 3x+30

6x-12 = 3x + 30

-3x -3x

3x-12=30

+12 +12

3x=42

~divide by 3 on both sides~

x = 14

Now that we know our x variable, we can substitute 14 into the expression for angle DHG.

6(14-2)

6(12)

72.

Answer:

∠DHG = 72°

Step-by-step explanation:

As ∠DHG and ∠EHF are vertical angles, they are congruent.

What are vertical angles?

Vertical angles are formed when two lines intersect, creating opposite angles. Those opposites are congruent (equal).

Equation:

∠DHG = ∠EHF

[6(x - 2)] = (3x + 30)

Step 1: Distribute 6 through the parentheses.

[tex]\implies 6(x) + 6(-2) = 3x + 30[/tex]

[tex]\implies 6x - 12 = 3x + 30[/tex]

Step 2: Subtract 3x from both sides.

[tex]\implies 6x - 3x - 12 = 30[/tex]

[tex]\implies 3x - 12 = 30[/tex]

Step 3: Add 12 to both sides.

[tex]\implies 3x - 12 + 12 = 30 + 12[/tex]

[tex]\implies 3x = 42[/tex]

Step 4: Divide both sides by 3.

[tex]\implies \dfrac{3x}{3} = \dfrac{42}{3}[/tex]

[tex]\implies \boxed{x = 14}[/tex]

Step 5: Substitute the value of x into ∠DHG to find its measure.

[tex]\implies \angle DHG = 6(14 - 2)[/tex]

[tex]\implies \angle DHG = 6(12)[/tex]

[tex]\implies \angle DHG = \boxed{72^\circ}[/tex]

Therefore, the measure of ∠DHG is 72°.

Step-by-step explanation:

The order of the scale from smallest to the largest is:

The smallest = 1 inch to 3 yards

The middle : 1 inch to 1.1 yards

The largest : 1 inch to 1 yard

A scale drawing is either a larger or smaller version of a diagram.  A scale factor provides information on the unit of conversion between the original image and the scale drawing.   A scale factor is the ratio of the length of the scale drawing to the length of the actual drawing.

The first step is to convert the given scale factors to the same units of measurement.

All of the measurements would be converted to yards

1 feet = 3 yards

1 inch to 3 yards

1.1 yards = 1 meter

1 inch to 1.1 yards

A line's equation is an algebraic way of expressing the collection of points that make up a line in a coordinate system. The many points that collectively make up a line on the coordinate axis are represented as a group of variables (x, y) to create an algebraic equation, also known as an equation of a line. Any line's equation can be used to determine whether a given point is on the line or not. A linear equation with a degree of one is the equation for a line.

The value of the function n(x) = -1 -x + 4 when x = -2,0, and 5 are  respectively.

Function:

A function is defined as a relationship between a set of inputs having one output each.

It can be represented as f(x).

Given,

Here we have the function

n(x) = -1 -x + 4

And we need to find the value of the function when x takes the values -2, 0 and 5.

To solve this one, then we have to put the value of x on the function and then we have to simplify it in order to get the value of the function.

For that first we have to put the value of x = -2, then we get,

n(-2) = -1 - (-2) + 4

n(-2) = -1 + 2 + 4

n(-2) = -1 +6

n(-2) = 5

Now we have to apply the value of x as 0, then we get the value of function as,

n(0) = -1 - 0 + 4

n(0) = -1 + 4

n(0) = 3

Finally we gave to apply the value of x as 5, then we get the value of n(5) as,

n(5) = -1 - 5 + 4

n(5) = -6 + 4

n(5) = -2

Therefore, the resulting values are 5, 3 and -2.

From the equation 3x + 59 = 120, the unit cost of the shirts is $20.33.

An equation is a mathematical statement used to equate two mathematical expressions.

To demonstrate equality, equations use the equation symbol (=).

The total amount spent on new clothes = $120

The number of shirts bought = 3

The cost of the pair of pants bought = $59

Equation of the situation is 3x + 59 = 120,where x = the unit cost of the shirts.

3x + 59 = 120

Subtract 59 from both sides:

= 3x + 59 - 59 = 120 - 59

Simplify both equations:

3x = 61

Divide both sides by 3:
