Answer:

x = y = 10

Step-by-step explanation:

Using the cosine ratio in the right triangle and the exact value

cos45° = $\frac{1}{\sqrt{2} }$ , then

cos45° = $\frac{adjacent}{hypotenuse}$ = $\frac{x}{10\sqrt{2} }$ = $\frac{1}{\sqrt{2} }$ ( cross- multiply )

x × $\sqrt{2}$ = 10 $\sqrt{2}$ ( divide both sides by $\sqrt{2}$ )

x = 10

Since the base angles are 45° then the triangle is isosceles and the 2 legs are congruent, then

x = y = 10

If a triangular cross-section with coordinates at (1, 1), (1, 4), and (3, 1) is rotated about the line x = 1, what will be the r

Alik [6]

Answer:

The resulting three-dimensional object will be a cone

Step-by-step explanation:

Plot the figure to better understand the problem'

we have

a triangular cross-section with coordinates at (1, 1), (1, 4), and (3, 1)

The draw in the attached figure

we know that

When rotating a a right triangle about a leg, the three dimensional figure formed is a cone

The radius of the cone will be equal to the base of right triangle and the height of the cone will be equal to the height of the triangle

The radius of the cone will be equal to 2 units and the height of the cone will be 3 units

see the attached figure to better understand the problem

A telemarketing company calls telephone numbers chosen at random. It finds that 30% of calls are not completed (the party does n

cupoosta [38]

Answer:

21%

Step-by-step explanation:

Actually there are three levels of process here.

If 100 calls are made only 70 calls are completed (since 30%not completed)

Out of these 70 completed we find that 40% i.e. 28 calls to a woman and 30% i.e. 21 go to a man.

28 females and 21 males

Out of 28 females 45% buy something = $0.45*28=12.6$

Out of 21 males 40% buy something = $0.4*21=8.4$

Total percent of calls result in a sale = $12.6+8.4=21$

So 21% of calls result in a sale
