A right triangle has legs that are 7 cm and 9 cm. what is the length of the hypotenuse? ​

Answer:

if pi is 3.14: 163.52 [tex]m^2[/tex]

if pi is just π: 264 - 32π [tex]m^2[/tex]

Step-by-step explanation:

22 x 12 = 264

4 x 4 = 16

16 x 2 = 32

16 x 3.14 = 50.24

264 - 50.24 x 2 = 163.52

Answer:

163.47

Step-by-step explanation:

We know the area of the whole rectangle by multiplying 12 by 22 to get 264. Now we just have to find the area of the circles and subtract it from the rectangle.

The area of a circle is πr^2. These circles' radii is 4, so 4^2π = 16π

Since there are 2 circles, double 16π to get 32π, 32π is equal to 100.53096491, rounded to 100.531. 264 - 100.531 = 163.469, rounded to 163.47

Answer:

Slope: [tex]\frac{7}{5}[/tex]

Y-intercept: -5

Step-by-step explanation:

If the equation of the line is not given but is graphed we can do in this way:

First, it's very simple to find the y-intercept: is -5 as you can see (the line touch the points -5 in the y line).

You know that the slope can be find by having two points (now we have the A(0; -5) (the y-intercept point).

As you can see, the line touch also the B(5; 2) perfectly.

Now we simply use this formula for find the slope:

[tex]s=\frac{yB-yA}{xB-xA}[/tex]

Let's substitute the value:

[tex]slope=\frac{2+5}{0+5}[/tex]

[tex]slope = \frac{7}{5}[/tex]

Answer:

Slope: 7/5

Y-intercept: -5

Answer:

Answer:

7^2 =49

Step-by-step explanation:

Exponents represent a number and how many times you multiply it by itself. So 5^2 is 5*5 or 4^3 is 4*4*4. So 7^2 is 7*7, which is 49!

Answer:

C

Step-by-step explanation:

Write the expression out

factor it

[tex](\frac{(x+1)(x-1)}{6x})(\frac{3x(x)}{x(x+1)})[/tex]

cancel out all everything that is the same and appears on both the top and the bottom

Cancel out:

(x+1)

(x)

(x)

leaves you with

[tex]\frac{3(x-1)}{6}[/tex]

3 goes into 6 '2' times so the 3 in the numerator cancels out too. The 6 in the denominator turns into a 2

This leaves you with the final answer of

[tex]\frac{x-1}{2}[/tex]

Answer:

C

Step-by-step explanation:

after factoring them

they become:

[tex]\frac{(x+1)(x-1)3x^2}{6x^2(x+1)}[/tex]

after dividing the numerator and denominator by 3x^2(x+1)

it becomes (x-1)/2

Answer:

D

Step-by-step explanation:

Just by looking at the data, you cannot answer A, B, or C because they are asking for who. There is no information on the data on WHO each piece of data is referring to. You can only answer D, which asks for HOW MANY. You can count how many 8s there are and answer the question.

The required scenario in the below solution part would lead to the given equation 2r + 15 = 25. The correct answer would be option (C).

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that is equal.

The equation is given in the question, as follows:

2r + 15 = 25

Let r be items you can buy at the concession stand.

You are going to the movies with some friends. You have $25 to spend. The movie costs $15 and each item at the concession stand costs $2. This equation shows how many items you can buy at the concession stand.

Thus, the required scenario in the above solution part would lead to the given equation.

Answer:

C, 5:9

Step-by-step explanation:

Answer:

5/9

Step-by-step explanation:

Context for variables

sw: number of sweaters

j: number of jeans  

sk: number of skirts

The following three equations are established from the question:

sw + j + sk = 120

sw/j = 8/3

j/sk = 3/4 or sk/j = 4/3

Dividing the first equation by j, we get:

sw/j + j/j + sk/j = 120/j

8/3 + 1 + 4/3 = 120/j

5 = 120/j

j = 120/5 = 24

sw = 24*8/3 = 64

sk = 24*4/3 = 32

After the replacement the new number of jeans and skirts are:

j' = 24 - 4 = 20

sk' =  32 + 4 = 36

the new ratio of jeans to skirts is:

j'/sk' = 20/36 = 5/9

Answer:

5 127/200 meters

Step-by-step explanation:

4 1/2 = 4 5/10 | 4/5 = 8/10

--------------------------------------

4 5/10 = 4.5 | 8/10 = 0.8

--------------------------------------

4.8 divided by 0.8 = 5.625

--------------------------------------

5.635 = 5 635/1000

635/1000 divided by 5 = 127/200

--------------------------------------

5 + 127/200 = 5 127/200

The unit rate in meters per year is 8/45 meter/year.

Given that, a tree in John's backyard has been growing for [tex]4\frac{1}{2} = \frac{9}{2}[/tex] years. The tree is 4/5 meters tall.

Unit rate can be defined as the ratio between two measurements with the second term as 1. It is considered to be different from a rate, in which a certain number of units of the first quantity is compared to one unit of the second quantity.

Now, unit rate = 4/5 ÷ 9/2

= 4/5 × 2/9

= 8/45 meter per year

Therefore, the unit rate in meters per year is 8/45 meter/year.
