Answer:

223.07

Step-by-step explanation:

Hey There!

So the first step of this problem is to find the equation for the area of a parallelogram and the area of a circle

The area of a parallelogram is equal to bh

$base x height$

the base is 20 and the height is 15

20x15=300

Now we want to find the equation for area of a circle

to find the area of the circle we use the formula $A = pi xr^{2}$

A = π x radius²

the radius is the diameter divide by 2

14/2=7 so the radius is 7

now we just plug 7 into the area of a circle formula

7²=49

49x3.14=153.86

But because it is a semi circle we divide by 2

153.86/2=76.93

Now to find the area of the object we subtract 76.93 from 300

300-76.93=223.07

Therefore the area of that object is 223.07

That is true because you are still dividing x by three either way

Preston can paint 375 square feet in 3 hours. At the same rate, how long would it take him to paint 812.5 square feet?

charle [14.2K]

Answer:

6.5 hours

Step-by-step explanation:

First try to find the rate he can paint per hour

375 ÷ 3 = 125 ft^2 per hour

Then try to find how long it should take it for him to paint 812.5 sq ft

812.5 ÷ 125 = 6.5 hours

Which equation is parallel to the line LaTeX: y=\frac{1}{2}x+3y = 1 2 x + 3and passes through the point (10, -5)?

sukhopar [10]

Answer:

$Equation\ of\ line:\ y=\frac{1}{2}x-10$

Step-by-step explanation:

$Let\ the\ required\ equation\ is\ y=mx+c\\\\where\ m\ is\ the\ slope\ of\ the\ equation\ and\ c\ is\ y-intercept\\\\It\ is\ parallel\ to\ the\ equation\ y=\frac{1}{2}x+3\\\\Hence\ slope\ of\ these\ two\ lines\ will\ be\ same.\\\\Slope\ of\ y=\frac{1}{2}x+3\ is\ \frac{1}{2}\\\\Hence\ slope\ of\ y=mx+c\ is\ \frac{1}{2}\Rightarrow m=\frac{1}{2}\\\\Equation:y=\frac{1}{2}x+c\\\\Line\ passes\ through\ (10,-5).\ Hence\ this\ point\ satisfies\ the\ equation\ of\ line.\\\\-5=\frac{1}{2}\times 10+c$

$-5=-5+c\\\\c=-10$

$Equation\ of\ line:\ y=\frac{1}{2}x-10$

Find the tangent of angle A (giving brainliest and thanks to all!)

Shtirlitz [24]

Answer:

Option B, 8 / 6

Step-by-step explanation:

Tangent = Opposite / Adjacent

Tangent of ∠A = Opposite / Adjacent

Tan(A) = 8 / 6 which is the same as Option B

Please help?? its unit rate so plz help tell me how to do it

Lelechka [254]

Answer:

1.2 dollars

Step-by-step explanation:

You have to divide the dollar count by the pound count.

So basically:

6/5

This gives you 1.2 dollars.

When you do unit rate, you just have to divide one value by the other value.

The value you divide by, and the value you divde, vary depending on what the question asks.

For instance, if this question asked what the pound count for 1 dollar would be, you would end up divide the 5 pounds by 6 dollars(5/6) instead of divideing the 6 dollars by 5 pounds like we did above(6/5).

Hope this helps!
