Using the formula for area of a circle: area = pi x r^2
You now have:
225pi ft^2 = pi x r^2
Divide both sides by pi:
225 = r^2
Take the square root of both sides:
r = 15
The radius is 15 feet.
The diameter is the radius x 2:
Diameter = 15 x 2 = 30 feet.
Answer: 30 feet.
5. If 10% of a number is 7. what is 80% of the number? 5600 O 70 O 0.7 O 56
Answer:
56
Step-by-step explanation:
just multiply it by 8 because 10% to 80% is ×8
Idek if that makes sense but its how it works in my head
What is the distance between the points? Round to the nearest tenth if necessary.(-4,-8) (2,2)
Answer: [tex]2\sqrt{34}[/tex] or, as a decimal, 11.7.
Step-by-Step Explanation:
1. Use the distance formula and substitute the values of the two ordered pairs.
[tex]\sqrt{(2-(-4))^{2}+(2-(-8))^{2}}[/tex]...
2. Multiply -1 by -4.
[tex]\sqrt{(2+4)^2+(2-(-8))^2\\}[/tex] ...
3. Add 2 and 4.
4. Raise 6 to the power of 2.
[tex]\sqrt{36+(2-(-8))^2}[/tex]...
5. Multiply -1 by -8.
6. Add 2 and 8.
7. Raise 10 to the power of 2.
[tex]\sqrt{36+100}[/tex] ...
8. Add 100 and 36.
9. Rewrite 136 as 2² · 34.
10. After factoring 4 out of 136 and rewriting as ... [tex]\sqrt{2^{2}(34)}[/tex], pull out terms from under the radical. It should look like this now: [tex]2\sqrt{34}[/tex]. That is your final answer!!
Hope that helps! Note: the unrounded decimal is 11.66190378.

Which list shows the set of integers? Select one: a. ..., -3 , -2 , -1 , 0 b. 1, 2, 3, ... c. ..., -3 ,-2 , -1 , 0 , 1 , 2 , 3 , ... d. 0, 1, 2, 3, ...
Hey love! <3
Answer:
C. ..., -3 ,-2 , -1 , 0 , 1 , 2 , 3 , ...
Step-by-step explanation:
Integers are inclusive of all numbers that are not a fraction, including negative numbers. The other sets would not be integers because all they have are whole and natural numbers.

Answer:
128 in.^2?
Step-by-step explanation:
a rectangle is also a parallelogram, so find the area of the rectangles.
if it is a 30-60-90 triangle, 8 inches is x, and to find the sides, it is either (x)sqrt(3), or in this case, 2x, so 16x8= 128?
Type the expression that results from the following series of steps:
Start with y, add 7, multiply by 3, then subtract 6.
Answer:
start with y
y
add 7
y+7
multiply by 3
3(y+7)
subtract 6
3(y+7)-6
therefore the answer is:
3y + 21 - 6
=
3y + 15 or 3(y+5)

The equation x2 = d has how many real solutions when d > 0?
Answer:
Two: [tex]\sqrt{d}[/tex] and [tex]\left(-\sqrt{d}\right)[/tex].
Step-by-step explanation:
The question is asking for the number of real numbers [tex]x[/tex] whose square is equal to [tex]d[/tex] (where [tex]d > 0[/tex].)
Naturally, the square root of [tex]d[/tex]: [tex]\sqrt{d}[/tex] would satisfy the requirement. [tex]\left(\sqrt{d}\right)^{2} = d[/tex].
However, keep in mind that [tex](x)^2[/tex] and [tex](-x)^{2}[/tex] have the same value. Therefore, if [tex]x =\sqrt{d}[/tex] would satisfy the equation, the opposite [tex]x = -\sqrt{d}[/tex] would also do.
Since [tex]d > 0[/tex], [tex]\sqrt{d}[/tex] and [tex]\left(-\sqrt{d}\right)[/tex] would both take real values.
Because [tex]d \ne 0[/tex], the value of [tex]\sqrt{d}[/tex] and [tex]\left(-\sqrt{d}\right)[/tex] would be distinct.
Hence, [tex]\sqrt{d}[/tex] and [tex]\left(-\sqrt{d}\right)[/tex] would correspond to the two real solutions of this equation.
The distance between Franklin City and Williamsville on a map is 3.2 inches. If the scale of the map is 1 inch = 15 miles, how many miles apart are the two cities?
Answer: 48 miles
Step-by-step explanation:
From the question, the distance between Franklin City and Williamsville on a map is 3.2 inches and the scale of the map is 1 inch = 15 miles.
The distance between the cities will be to multiply 3.2 by 15 to get the number of miles since 1 inch = 15 miles. This will be:
= 3.2 × 15 miles.
= 48 miles
The distance between Franklin City and Williamsville is 48 miles.
Answer:
48 Miles

Two forces of newtons and newtons act on a point. The resultant force is newtons. Find the angle between the two forces.
Question: Assume the complete question as, Two forces of 20 Newton’s and 30 Newton’s² act on a point. The resultant force is 40 Newton’s. Find the angle between the two forces
Answer:
75.5°
Step-by-step explanation:
From the question,
Using cosine rule,
R² = P²+Q²-2PQcosθ................... Equation 1
Where θ angle between the the two forces.
Given; R = 40 Newton, P = 20 Newton, Q = 30 Newton.
Substitute these values into 1
40² = 20²+30²-[2×20×30(cosθ)]
1600 = 400+900-(1200cosθ)
1600 = 1300-1200cosθ
1200cosθ = 1600-1300
1200cosθ = 300
cosθ = 300/1200
cosθ = 0.25
θ = cos⁻¹(0.25)
θ = 75.5°
Hence the angle between the forces is 75.5°
If x = 2 and y = 6 , evaluate the following expression: 2 ( x + y )
Answer:
Step-by-step explanation:
If x = 2 and y =6
Then
2 ( x+ y)
= 2 ( 2 + 6)
= 2 * 8
= 16
hope it helps :)
Answer:
16
Step-by-step explanation:
you will do 2 + 6 = 8
so it = 8
x=2
y=6
and than u will 8 x 2 = 16
the answer is = 16
