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.

Carolyn says that point A and point B represent opposite integers. a. What is the opposite of the integer represent by point A?
zysi [14]

we are given

point-A= -7

point-B=8

(a)

opposite of point-A is negative of point-A value

so,

opposite of point-A is -(-7)

opposite of point-A is 7

opposite of point-B is negative of point-B value

so,

opposite of point-B is -8

opposite of point-B is -8

(b)

we can see that

opposite of point-A is 7

opposite of point-B is -8

they are not equal

so, this argument is FALSE.......Answer

sp2606 [1]

Answer:

$5.35.

The number of checks written after the first 10 = 24 - 10 = 14.

The fees for these checks = 14 * 0.10
