Find the scale factor of the two cylinders:

Figure A has an r of 4 and figure B has an r of 2:

2 / 4 = 0.50, so Figure B is half the size of Figure A.

Since you want the volume, which is measured in cubic units, you need to cube the scale factor:

0.5^3 = 0.125

Multiply the volume of Figure A by the scale factor:

352 x 0.125 = 44 cubic feet.

Dana buys dress shirts from a clothing manufacturer for s dollars each, and then sells the dress shirts in her retail clothing s

nydimaria [60]

Answer:

Consider the complete question is,

Dana buys dress shirts from a clothing manufacturer for s dollars each, and then sells the dress in her retail clothing store at a 35% markup

a. Write the markup as a decimal

b. write an expression for the retail price

c. What is the retail price of a dress shirt that Dana purchased for 32.00

d. How much was added to the original price of the dress shirt?

Reference : brainly.com/question/2202598

Solution :

Here, s represents the price of each dress shirt,

a. Since, markup percentage = 35%,

Thus, the markup in each shirt = 35% of price of each dress shirt

= 35% of s

$=\frac{35s}{100}$

= 0.35s

b. Retail price = original price + markup

= s + 0.35s

= 1.35s

c. if s = 32,

Retail price = 1.35(32) = 43.2

d. The added amount in original price = Retail price - original price

= 43.2 - 32

= 11.2

A piling for a high-rise building is pushed by two bulldozers at exactly the same time. One bulldozer exerts a force of 1250 pou

Yanka [14]

Answer:

Resultant force will act on 65° N of W.

Step-by-step explanation:

As given in the question one bulldozer exerts force of 1250 pounds in western direction and 2650 pounds in northern direction and we have to find angle A which is an angle between 1250 pounds of force and resultant force F.

Therefore tan A= Force on North direction/ Force on west direction = 2650/1250 = 2.12

⇒ $A=tan^{-1}(2.12)$

A = 64.75

A = 65° North of west.

Svetach [21]

The minimum score to join the genius society is 130.

What is the probability?

Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.

Given

A genius society requires an IQ that is in the top 2% of the population in order to join.

If an IQ test has a mean of 100 and a standard deviation of 15.

The top 2%, you have to have an IQ higher than 98% of the population (100% - 2%).

This is also known as the 98th percentile.

For this problem, you are given the probability and need to determine the raw score.

The closest probability is 0.97982 and that corresponds to a z-score of 2.05.

$\rm z - score=\dfrac{x-mean}{standard \ deviatiion}\\\\2.05=\dfrac{x-100}{15}\\\\x-100=15\times 2.05\\\\x-100=30.75\\\\x=100+30.75\\\\x=130.75$

Hence, the minimum score to join the genius society is 130.
