A test tube is cylindrical in shape with a length of 152 mm and a radius of 6.5 mm. What is the volume of the test tube? Report

vazorg [7]

Answer:

20165

Step-by-step explanation:

Given:

Length/height (h) of cylindrical test tube = 152 mm

Radius of cylindrical test tube = 6.5 mm

Volume = $\pi r^2h$

Required:

Volume of cylinder to nearest whole number

Solution:

The volume is given as $V = \pi r^2h$

Take π as 3.14 and plug the values of r and h into the volume formula.

$V = 3.14*6.5^2*152$

$V = 3.14*6.5*152 = 20165.08$

Volume of the test tube = 20165 mm³ (nearest whole number)

What are the factors of the expression x^2+x-20?

tatyana61 [14]

Answer:

(x-4)(x+5)

Step-by-step explanation:

Find 2 numbers knowing sum (1) and product (-20). To find them, factor pairs of (-20) --> (-2,10) (-4,5). This sum is 1=b. Then, these 2 numbers are: - 4 and 5. Y=(x-4) (x+5). Hope this helped :)

Question 2 (Essay Worth 10 points)

icang [17]

Answer:

Part A: 1 solution

Part B:

3(2x-7)=3

6x-21=3

+21 +21

6x=24

/6 /6

x=4

Step-by-step explanation:

First you distribute 3(2x-7)=3 to 6x-21=3. Next you do inverse operations by adding 21 to both sides of the equation to get 6x=24. Finally you divide both sides by 6 to get x=4
