Answer:

A.78

Step-by-step explanation:

\frac{30}{25sec} -----> \frac{78}{65sec} (scale by 2.6)

You cant get the answer by following these steps.

1. To find out how much we must increase with our scaling we must divide the denominators.

\sqrt[25]{65}= 2.6

2. Then, we do the scaling. Multiply the numerator and the denominator by 2.6.

num- 30 x 2.6= 78.0 (DONT FORGET UR DECIMALS)

dem- 25 x 2.6 = 65

3. Now you have your answer and all you need to do is show it in fraction form as seen below the words "step by step explanation"

Gook luck and pls give brainlist

Solve the equation <br>y=2x-4, 3x+y=11​
Ostrovityanka [42]

Answer:

(3, 2)

Step-by-step explanation:

Given the 2 equations

y = 2x - 4 → (1)

3x + y = 11 → (2)

Substitute y = 2x - 4 into (2)

3x + 2x - 4 = 11

5x - 4 = 11 ( add 4 to both sides )

5x = 15 ( divide both sides by 5 )

x = 3

Substitute x = 3 into (1) for corresponding value of y

y = (2 × 3) - 4 = 6 - 4 = 2

Solution is (3, 2)

A prism with a base area of 8 cm² and a height of 6 cm is dilated by a factor of 5/4 .
Andrei [34K]
The volume of the original prism is calculated by multiplying the area of the base by the height,
                               volume = (8 cm²)(6 cm) = 48 cm³
By the word dilated we mean to say that the dimensions of the new prism is 5/4 times that of the original solid. If we let x be the volume of the new solid,
                           x / 48 cm³ = (5/4)³
The value of x from the equation above is equal to 93.75 cm³.

rusak2 [61]

Answer:

Ok,You need to put the value of x that appears in the table to give you the result of h (x)

1.h(x)=4x+5

h(-5)=4(-5)+5

h(-5)= -20+5

h(-5)= -15

2.h(-1)=4(-1)+5

  h(-1)= -4+5

  h(-1)= 1

3. h(1)=4(1)+5

   h(1)=4+5

   h(1)=9

4. h(3)=4(3)+5

   h(3)=12+5

   h(3)=17

5. h(4)=4(4)+5

    h(4)=16+5

    h(4)=21

Step-by-step explanation:

  x                  h(x)

-5                    -15

-1                       1

 1                       9

 3                      17
