Answer: $77

Step-by-step explanation: 77 is the correct answer because the price increased by 77 because 77 is the difference between the two, and how i got 77 was to subtract 140 ( the earlier price) from 217 ( the price that it changed to), i hope you found this helpful...

Solve each inequality. The variable should be on the left-hand side in your solution.

lara [203]

Answer:

x≤ −96 /23

Step 1: Simplify both sides of the inequality.

Step 2: Subtract 1/8x from both sides.

Step 3: Subtract 12 from both sides.

Step 4: Multiply both sides by 8/23.

Which line shows theINITIAL error in volume work?

aliina [53]

In step 2, V = $\frac{4}{3}(3.14)(37.5)$ show the error in volume work.

Solution:

Given data:

The steps shows it is sphere.

Radius of the sphere = 12.5

The value of π = 3.14

Volume of the sphere = $\frac{4}{3} \pi r^3$

Step 1:

$$V=\frac{4}{3} (3.14)(12.5)^3$

$$V=\frac{4}{3} (3.14)(12.5)(12.5)(12.5)$

Step 2:

$$V=\frac{4}{3} (3.14)(1953.125)$

Step 3:

$$V=\frac{4}{3} (6132.81)$

Step 4:

V = 8177.08 cubic units

This is the correct solution.

But in the given options, in step 2, 12.5 is multiplied by 3.

That is not the correct step. You have to do 12.5 × 12.5 × 12.5.

Hence in step 2, V = $\frac{4}{3}(3.14)(37.5)$ show the error in volume work.
