Answer:

24.9 meters to the nearest tenth.

Step-by-step explanation:

We have 2 similar triangles here so:

21/8 = h/9.5

h = 21* 9.5 / 8

= 24.94 m = the height of the tank.

Answer:

\boxed{24.9375}

Step-by-step explanation:

→ Write out the direct proportion equation

y = kx

→ Substitute in x = 21 and y = 8

8 = 21k

→ Divide both sides by 8 to isolate k

k = 2.625

→ Substitute back into original equation

y = 2.625k

→ Substitute 9.5 for k

y = 2.625 × 9.5 ⇔ 24.9375

On the function machine shown below, the function rule is given as a variable expression. When the output is 99, what is the inp
beks73 [17]

Answer: option d.

Step-by-step explanation:

We have the function:

y = f(x) = x^2  - 1

The output is 99 when y = 99, and the input is x.

Then we need to solve:

y = 99 = x^2 - 1

for x.

99 = x^2 - 1

99 + 1  =x^2

100 = x^2

√100 = x

10 = x

The correct option is d, input equals 10.

Help please, what’s: 5x-7+2-2x=-26
svetoff [14.1K]

Answer:

7

Let's solve your equation step-by-step.

5x−7+2−2x=−26

Step 1: Simplify both sides of the equation.

5x−7+2−2x=−26

5x+−7+2+−2x=−26

(5x+−2x)+(−7+2)=−26(Combine Like Terms)

3x+−5=−26

3x−5=−26

Step 2: Add 5 to both sides.

3x−5+5=−26+5

3x=−21

Step 3: Divide both sides by 3.

3x

3

=

−21

3

x=−7

Answer:

x=−7
