A circle is cut out of a piece of plywood that is 10in. square.Find the area of the circle and How many square inches of plywood are thrown away?

If you can solve this AND show your work you get brainlist.

Answers

Answer 1

Answer:

Area of the circle: 78.54in^2

Plywood thrown away: 21.46 in^2

Step-by-step explanation:

So the area of the square is 100 in. To find the area of a circle, you use the formula (pi)r^2 where r is the radius, in this instance it is 1/2 of ten which is 5. Then, plug it into the formula which will get you (rounded to the nearest hundred) 78.54in^2. Then, subtract from the total plywood area. Please mark brainliest :)

A right triangle has a hypotenuse of 8 feet. One leg has a length of 5 feet. How long is the other leg?
A. 5 ft.
B. V39 ft
C. V89 ft
D. 13 ft.

Answers

Answer:

B

Step-by-step explanation:

The formula a^2 + b^2 = c^2 can be used to find any of the legs of the triangle. a and b are legs of the triangle and c is the hypotenuse. We can substitute known values into the equation:

a^2 + b^2 = c^2

One leg is 5 so we can put that in as a. And c, the hypotenuse, is 8.

5^2 + b^2 = 8^2

Now solve for b.

First, square 5 and 8

25 + b^2 = 64

Subtract 25 from both sides

b^2 = 39

Take the square root of both sides

b = √39

What is the value of x in this triangle? What is the value of each angle?

Answers

Answer:

x=17

Step-by-step explanation:

we know the 25 + 90 = 115 so we need the other one to make it 180 degrees.

180-115= 65

so we need 65 more degrees to get 180

now 3x + 11= 65  first step subtract 11 on both sides

you now get 3x = 54 then 2nd step is divide 3 on both sides

and now you get x=17 so

Answer:

Step-by-step explanation:

The entire value of the triangle is 180 degrees.

If you subtract 25 from 180 you are left with 155

Then Subtract 90 from 155 which will leave you with 65

Go on to subtract 11 from 65 having to be with 54 degrees left

Finally you will dived 54 by 3 and you are left with 18

3 x 18 = 54

54 + 11 = 65

Therefore x will equal to 65 degrees

What is the fewest number of people surveyed if exactly 93.6% of people completed a survey?

number line.

Answers

Answer:

Step-by-step explanation:

7

the fewest number of people surveyed is 125, i’ll explain why.

the percentage of people that finished the survey is 93.6%, given.

this percentage as a fraction is p, (being the people) = 93.6/100, so, p = 93.6/100.

you then multiple the fraction 93.6/100 by 10, which is: p = 936/1000. then, reduce the fraction.

p = 117/125.

the fraction can’t be reduced any further, so that’s your answer.

Answers

Answer:

X = 11/6

Step-by-step explanation:

Answer:

b) x = -11/6

Step-by-step explanation:

Given equation,

→ (-2/3)(3x - 4) + 3x = 5/6

Now the value of x will be,

→ (-2/3)(3x - 4) + 3x = 5/6

→ (-6x + 8)/3 + 3x = 5/6

→ (-6x + 8 + 9x)/3 = 5/6

→ -6x + 8 + 9x = (5/6) × 3

→ 3x + 8 = 5/2

→ 3x = (5/2) - 8

→ x = (-11/2) × (1/3)

→ [ x = -11/6 ]

Hence, value of x is -11/6.

Since 90º is the measure of a right angle, another way of saying that two angles are complementary is that together they form a right angle

Step-by-step explanation:

x - 0.15x + 0.09(0.85x)

x is the initial amount, -0.15x is subtracting 15% of the original amount (leaving 0.85x), and 0.09(0.85x) is the 9% tax.

x - 0.15x + 0.09(0.85x)

= 0.85x + 0.0765x
