Answer: About 14.14 in^3

Step-by-step explanation:

We know that the circumference of a sphere is C=2πr. We are given that the circumference is 9.42 in. We can find the radius to get our volume.

$9.42=2\pi r$

$4.71=\pi r$

$r=1.5\\$

Now that we know radius, we can find our volume.

$V=\frac{4}{3} \pi r^3$

$V=\frac{4}{3} \pi (1.5)^3$

$V=14.14in^3$

Solve the triangle give the measure of y

pishuonlain [190]

Given:

In triangle $BGU,BG=x,GU=7,BU=y,m\angle U=90^\circ,m\angle B=44^\circ$ .

To find:

The value of y.

Solution:

In a right angle triangle,

$\tan \theta=\dfrac{Perpendicular}{Base}$

In triangle BGU,

$\tan B=\dfrac{GU}{BU}$

$\tan 44^\circ=\dfrac{7}{y}$

$0.966=\dfrac{7}{y}$

Isolating y, we get

$y=\dfrac{7}{0.966}$

$y=7.2463$

$y\approx 7.2$

Therefore, the correct option is A.

A restaurant bill is $27.50. If the sales tax is 7.5% and a 20% tip is added, what is the total cost of the meal?

7nadin3 [17]

Answer:

35.06

Step-by-step explanation:

So you have to multiply 27.50 by 0.075 to find the sales tax.

2.0625 ≈ 2.06

If the tip is off the original price, you multiply 27.50 by 0.2.

5.5

The whole meal is 27.50 + 5.50 + 2.06 = 35.06
