7. Find the measure of each
marted angle

Answer:

The answer to the question is 540°

Step-by-step explanation:

The reason to the answer is:-

There is a formula which is (n - 2) × 180

n is the number of sides the shape has, and there is 5 sides so we subtract 5 - 2 = 3

Therefore, 3 × 180 = 540°

I hope this answer helps!

Step 2: Find Sum

Answer:

he height of a triangle is 8m less than the base. The area is 10cm^2. Find the height and the base.

I have tried the equation 10=b(b-8)(1/2).

b(b-8) = 20

b^2 - 8b - 20 = 0

Factor:

b^2-10b + 2b-20 = 0

Hey there!

The answer to your question is [tex]4x^2+2x-2[/tex]

Given:

[tex]x^2-3x+7[/tex] [tex]and[/tex] [tex]3x^2 +5x-9[/tex]

First, we can start by adding like terms. The following are like terms:

[tex]x^2[/tex] [tex]and[/tex] [tex]3x^2[/tex]

[tex]-3x[/tex] [tex]and[/tex] [tex]5x[/tex]

[tex]7[/tex] [tex]and[/tex] [tex]-9[/tex]

Now, we can add these pairs together, giving us:

[tex]4x^2[/tex]

[tex]2x[/tex]

[tex]-2[/tex]

Now, add all this together, and we get our answer as:

[tex]4x^2 + 2x - 2[/tex]

Answer: 14:35 hrs

Step-by-step explanation:

Missing time that Ron left was 07:00 hrs  

Ron left the house at 07:00 hrs. If he arrived back to the house 7 hours and 35 minutes later, you can find out what time he arrived by simply adding the time he left to the time he stayed outside:

= 7 + 7hrs 35 minutes

= 14 hrs 35 minutes

= 14:35 hrs

Answer:

A. $198 and B. 25

Step-by-step explanation:

11 × 18 is 198, which is the first answer.

If you take 275 and divide it by 11, you get how many hours you have worked, which would be 25. :)

Answer:

a. $198

b. 25 hours

Step-by-step explanation:

a. You earn $11 per hour, and so if you work 18 hours, you multiply "11 x 18" to find out how much money you would make during that time period.

b. To find out how many hours you are required to work to be paid $275, you simply need to divide by 11, seeing as how that is how much you would be paid per hour. So, the equation would look like this: "275/11 = 25"

Answer:

65.974 Square-miles

Step-by-step explanation:

We do 3.14*2^2=12.566

We then do 3.14*5^2=78.54

78.54-12.566=65.974

The change in the area of the circular oil spill is given by the equation

A = 65.973 miles²

A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle

The perimeter of circle = 2πr

The area of the circle = πr²

where r is the radius of the circle

The standard form of a circle is

( x - h )² + ( y - k )² = r²,

where r is the radius of the circle and (h,k) is the center of the circle

Given data ,

Let the change in area of circular oil spill be A

Now , the equation will be

The initial radius of the circular oil spill r = 2 miles

The increased radius of the circular oil spill R = r + 3

R = 5 miles

Now , the initial area of the circular oil spill = πr²

Substituting the values in the equation , we get

The initial area of the circular oil spill = 4π miles²

Now ,

The increased area of the circular oil spill = πR²

Substituting the values in the equation , we get

The increased area of the circular oil spill = 25π miles²

And , change in area of circular oil spill A = 25π miles² - 4π miles²

On simplifying the equation , we get

The change in area of circular oil spill A = 21π miles²

The change in area of circular oil spill A = 65.973 miles²

Therefore , the value of A is 65.973 miles²

Hence , the change in circular area is 65.973 miles²
