I need help with 8z-22=3(3z+11)-z with work please!

Answers

Answer 1

Answer: 8z - 22= 3(3z +11) - z
8z - 22= 9z + 33 - z
8z - 9z + z = 33 + 22
0 = 55
Conclusion: No Solution

Write a unit rate for the situation
250 words in 5 minutes

Answers

To write a unit rate we have to find out, something per something. Here we will find out how many words per min. TO do this we will divide the amount of words (250) by the amount of minutes (5). Lets do it:-

250 ÷ 5 = 50
50 words per min.

CHECK OUR WORK:-

50 × 5 = 250
We were RIGHT!!

So, a unit rate for the situation "250 words in 5 minutes" is 50 words per min.

Hope I helped ya!! xD

250 words in 5 minutes
To find how many words per minute, divide 250 by 5.
That would give you 50 words per minute.
This would be a linear equation because there is a steady unit rate.
The rate is 5 so the equation is
y=5x
Hope this helps.

Translate the sentence into an equation.The difference of a number times 3 and 8 is 2. Use the variable c for the unknown number. How do I figure this out?

Answers

I hope that this is what you are looking for....

C X 3(8) = 2

The parenthesis means to multiply again.

Hope that this helps... :)

-3c+8=2 you minus 8 on both sides of the equation then you'll get -6 then divide -3c by -6 so c equals to 2 c=2

An ice cream cone is made of a cone shape and half a sphere shape. Explain how you could find the volume of the entire ice cream cone.

Answers

Call the radius r and the height of the cone h. The formula for the volume of a cone is r^2*h*pi/3, and the formula for the volume of a sphere is 4r^3/3, so half of a sphere has volume 2r^3/3. Adding these, our answer is:

$(r^2 h \pi+r^3)/(3)$

A building that is 100 for tall casts a shadow that makes a 30 degree angle. Approximately how long in feet is the shadow across the ground?

Answers

Answer: 173.20 ft

Step-by-step explanation:

Observe the attached image. To know how long the shadow is, we must find the length of the adjacent side in the triangle shown. Where the opposite side represents the height of the building

By definition, the function $tan (x)$ is defined as

$tan(x) = (opposite)/(adjacent)$

$opposite = 100\ feet\nx=30\°$

$adjacent = l$

Then

$tan(30\°) = (100)/(l)$

$l = (100)/(tan(30\°))$

$l = 173.20\ ft$

Hello!

The answer is:

The shadow is 173.20 feet

Why?

To solve the problem, we need to calculate the projection of the building's shadow over the ground.

We already know the height of the building (100 feet), also, we know the angle of elevation (30°), so, we can use the following formula to calculate it:

$Tan(\alpha)=(y)/(x)=(height)/(x)\n\nx=(height)/(Tan(\alpha) )$

Now, substituting the given information and calculating, we have:

$x=(height)/(Tan(\alpha) )$

$x=(100feet)/(Tan(30\°) )=173.20feet$

Have a nice day!
