Answer:

70.5°

Step-by-step explanation:

Use the law of sines.

$\frac{Sin 45}{4.5}=\frac{sin x}{6}$

Multiplying both sides of the equation by 6 will result

$sin x = 0.942809....$

Then just use the inverse sine function on your calculator

$sin^{-1}sinx=sin^{-1}0.942809...$

$x=70.5$

A company sells products on the Internet through an email list. They predict that they sell one $40 product for every 85 people

mariarad [96]

So first you have to find how many 85's are in 68000 because it says "for every 85" 68000 divided by 85 = 800 and it also says one 40 dollar product

for each so 800 x 40 = (figure out 800 x 40)

Hope this helped as well as it being correct!

The age of Mark’s dad is 4 less than twice Mark’s age. The sum of their ages is 95. Find their ages.

kvasek [131]

D = 2m - 4 (Dad's age is 4 less than twice Mark's)
m + d = 95 (their ages total 95)

We have a value for d, so plug it in:
m + 2m - 4 = 95
Simplify:
3m - 4 = 95
Add 4 to both sides:
3m = 99
Divide by 3:
m = 33

An artist makes a cone-shaped sculpture for an art exhibit. If the sculpture is 7 feet tall and has a base with a circumference

Ivenika [448]

Answer:

The volume of the sculpture is 111.439 $feet^{3}$

Step-by-step explanation:

In this question, we are concerned with calculating the of the sculpture made given the information in the question.

To get the volume, we use the formula for the volume of a cone.

Mathematically, V = 1/3 × π × $r^{2}$ × h

From the question, we have the height but we do not know what the radius is. The information concerning the radius given in the question is that the circumference of the base of the cone is 24.492 feet

Mathematically, the formula for the circumference of a circle is

C = 2×π×r

From the question, we can identify that the circumference is 24.492 feet and we are expected to use the value of 3.14 for π

We plug these values into the equation for the circumference

24.492 = 2 ×3.14 × r

r = $\frac{24.492}{2 * 3.14}$

r = 24.492/6.28

r = 3.9 feet

We now plug this value of the radius alongside the value for the height into the equation for the volume given above

V = 1/3 × 3.14 × $3.9^{2}$ × 7

V = 111.4386 = 111.439 $feet^{3}$ to the nearest hundredth
