Answer:

Step-by-step explanation:

Amari ran 3/4 distance Mary ran

A = 3/4  M

Amari ran 12 miles

12 = 3/4 M                Multiply by 4

12 * 4 = 3*M              Combine    

48 = 3M                   Divide by 3

48/3 = M

M = 16

So Mary ran 16 miles.

Answer:

7.1 cm

Step-by-step explanation:

The diagonal of a cube connects two opposite corners.

You can use the diagonal of a cube in a right triangle in which it is the hypotenuse. The legs of the triangle are a diagonal of a face and an edge.

Let the length of the edge be s.

a^2 + b^2 = c^2

[tex] s^2 + 10^2 = (\sqrt{150})^2 [/tex]

[tex] s^2 + 100 = 150 [/tex]

[tex] s^2 = 50 [/tex]

[tex] s = \sqrt{50} [/tex]

[tex] s = 5\sqrt{2} [/tex]

s = 7.1

Answer: 7.1 cm

Step-by-step explanation:

Hey there!!

It 's so simple.

You remember common property of triangle. (i.e sum of interior angle of a triangle is 180°)

So,

77° + 31° + x = 180°

x + 108° = 180°

x = 180° - 108°

Therefore the measure of angle x is 72°.

Hope it helps....

Answer:

220 10 4

Step-by-step explanation:

We can write a ratio:

15/5 = 36/x

Let "x" equal the unknown part of the triangle.

Solution:

15/5 = 36/x

~Cross multiply

15x = 180

~Divide 15 to both sides

x = 12

Best of Luck!

Answer:

Around 22200 dollars

Step-by-step explanation:

Firstly, it was depreciating 20% per year for 17 years. So, if we were to go back in time, it would be appreciating by 25%. Therefore, after doing the plugging in, it is 500 * 1.25^17. The initial value is around 22200. It is around 22204, to be exact.

Answer:

add ans subtract like normal

Step-by-step explanation:

Step-by-step explanation:

To add decimals, follow these steps: Write down the numbers, one under the other, with the decimal points lined up. Put in zeros so the numbers have the same length .Then add, using column addition, remembering to put the decimal point in the answer.

subtraction also in the same way only place the large no up and small down and do subtraction.

Answer:

b = y - mx

Step-by-step explanation:

Given

y = mx + b ( subtract mx from both sides )

y - mx = b

Answer:

Step-by-step explanation:

x + 3•(+1) = 2•x + 4•(-1)

x + 3  =  2x - 4

  -3         -3

 x  =  2x - 7

-2x      -2x

- x  =  -7

÷(-1)     ÷(-1)

  x = 7

Answer: approximately 7.07

Step-by-step explanation:

The distance formula is [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]. Since we are given teo points, we can plug them in and solve.

[tex]d=\sqrt{(4-3)^2+(0-(-7))^2}[/tex]       [parenthesis]

[tex]d=\sqrt{(1)^2+(7)^2}[/tex]                         [exponent]

[tex]d=\sqrt{1+49}[/tex]                                [add]

[tex]d=\sqrt{50}[/tex]                                      [square root]

[tex]d=7.07[/tex]

The distance is approximately 7.07.

Answer:

[tex]h<-15[/tex]

Step-by-step explanation:

[tex]-18+7h>12+9h[/tex]

Add 18 to both sides:

[tex]-18+7h+18>12+9h+18[/tex]

[tex]7h>9h+30[/tex]

Subtract 9h from both sides:

[tex]7h>9h+30[/tex]

[tex]-2h>30[/tex]

Multiply both sides by -1 and flip the symbol:

[tex]\left(-2h\right)\left(-1\right)<30\left(-1\right)[/tex]

[tex]2h<-30[/tex]

Divide both sides by 2:

[tex]\frac{2h}{2}<\frac{-30}{2}[/tex]

[tex]h<-15[/tex]

Question: 1

 Subtract 9 from each side.

 Divide each side by 2

 Add 11 to each side.

 Divide each side by 4

Question: 2

10x +2 = 32

10x = 30

x = 3

Question: 3

-4c = -2

c = 1/2 or 0.5

Question 4:

1.1x + 1.2x -5.4 = -10

x = -2

Question: 6

6(5 − 8v) + 12 = −54

6( 5 - 8v ) = -66

( 5 - 8v ) = -11

-8v = -16

v = 2

Answer:

Sample response:

Both inequalities use the division property to isolate the variable, y. When you divide by a negative number, like –7, you must reverse the direction of the inequality sign. When you divide by a positive number, like 7, the inequality sign stays the same. The solution to the first inequality is y > -23, and the solution to the second inequality is y <>

Answer:

The answer is

Step-by-step explanation:

The midpoint M of two endpoints of a line segment can be found by using the formula

[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(12,-7) and (-6,15)

The midpoint is

[tex]M = ( \frac{12 - 6}{2} , \: \frac{ - 7 + 15}{2} ) \\ = ( \frac{6}{2} \: , \: \frac{8}{2} )[/tex]

We have the final answer as
