A circular fountain has 132 feet of railing around it. What is the area of the fountain to the nearest square foot? Use 3.14 for π. *
Answer:
139
Step-by-step explanation:
First we need to find diameter 132/3.14=42 rounded
Then we halve it to find radius 42/2=21
Formula for area is radius x radius x 3.14
21 x 21 = 441 x 3.14 = 138.74 round up is 139
Answer:
18.8 feet, 59.1 feet to the nearest tenth
Step-by-step explanation:
The diameter is the line drawn that divides the circle into two while the circumference is the perimeter of the circle. Both are a measure of the radius of the circle.
The diameter D = 2r where r is the radius of the circle
The circumference = 2Πr = ΠD where Π = 22/7
Given that the circular fountain has a radius of 9.4 feet
Its diameter = 2 × 9.4 feet = 18.8 feet
The circumference = 22/7 × 18.8 feet
=59.09 feet
≈ 59.1 feet to the nearest tenth

Which expression uses the commutative property to make it easier to evaluate 3/5·1/4·25
A.25·4·3/5
B.5/3·25·1/4
C.3\5·25·1\4
D.3/5·1/25·1/4
Answer:
C
Step-by-step explanation:
The expression that uses the commutative property is 3/5 × 25 × 1/4
What is the commutative property?The commutative property is a math rule that says that the order in which we multiply numbers does not change the product.
Given is an expression 3/5 × 1/4 × 25
We know that,
The commutative property of multiplication states that:
A × B × C = B × C × A
Using the above equation, we have the result of the commutative property to be:
3/5 × 1/4 × 25 = 3/5 × 25 × 1/4
Hence, the expression that uses the commutative property is 3/5 × 25 × 1/4

what's 9x - 7i > 3 (3x - 7u) ?
Step-by-step explanation:
9x-7i>9x-21u
-7i>-21u
i<3u
The solution to the given inequality 9x - 7i > 3(3x - 7u) is i < 3u.
Given that:
Inequality: 9x - 7i > 3 (3x - 7u)
To solve the inequality 9x - 7i > 3(3x - 7u), follow these steps:
Step 1: Distribute the 3 on the right side of the inequality as:
9x - 7i > 9x - 21u.
Step 2: Simplify the inequality.
9x - 9x - 7i > - 21u.
Step 3: Rewrite the inequality.
After cancelling out the 9x terms, we are left with -7i > -21u.
Step 4: Divide both sides by -7.
i < 3u
Therefore, the solution to the inequality 9x - 7i > 3(3x - 7u) is i < 3u.

Which list correctly compares the changes, in yards, in the football team's position on the field?
A. -7<-4< 0 < 7
B. -4 <-7 <0 <7
C. 0<-7<-4 <7
D. 0<-4 <-7<7
Answer:

Step-by-step explanation:
Given
Change: -4, 7, -7 and 0
Required
Compare them
From the list of given options, we can observe that the inequality < is used in all options.
This implies that we arrange from least to highest
The least is -7
Then, -4
Then 0
And lastly, 7
So, we have:

What is the value of p in the proportion below?
20/6 = p/12
O 2
O 10
O 40
O 72
Answer:
p = 40
Step-by-step explanation:
20/6 = p/12
Reduce the fraction on the left side.
10/3 = p/12
Cross multiply.
3p = 10 * 12
Divide both sides by 3.
p = 10 * 4
p = 40

A company called Blurb prints books. According to its advertisement, you get a 15% discount on all orders of 51 or more copies of the same book (up to 100 copies). Is the cost per order a linear function of the number of copies you order (up to 100)?
Answer:
Yes, the cost per order is a linear function of the number of copies you order (up to 100).
Step-by-step explanation:
Let;
y = Total cost of order from one copy up to 100 copies or dependent variable
a = Cost of 50 copies or fixed intercept
x = Cost of 51 copies or more up to 100 copies or dependent variable, i.e. 51 = x [tex]\leq[/tex] 100
b = Coefficient of x = 1 - Discount rate = 1 - 15% = 1 - 0.15 = 0.85
We can therefore represent have a function as follows:
y = a + bx ........................ (1)
Substituting b = 0.85 into equation (1), we have:
y = a + 0.85x ...................... (2)
Equation (2) implies that as b equal to 51 or more up to 100, y also increases. Equation (2) is therefore an example of linear function which will give an upward sloping straight line and can be rewritten as:
y = f(x) = a + 0.85x ................. (3)
Therefore, the cost per order is a linear function of the number of copies you order (up to 100).
