The figure below is composed of a rectangle and two quarter circles. What is the area of the figure?
A) 132.97 cm^2
B) 94.48 cm^2
C) 75.24 cm^2
D) 209.94 cm^2
Answer:
A) 132.97 cm²
Step-by-step explanation:
first, find the area of the rectangle.
8×7=56
then, find the area of the two quarter circles (ill just calculate for a half circle since bith quarters are the same)
the radius is 7, qnd the formula for a half circle is 1/2(πr2 )
so just plug in and solve
1/2(×7²)
π×7² is 153.86
153.86/2 is 76.93
then add those two areas together
76.93+56 = 132.96 (i used 3.14 for pi, but im assuming this calls for the actual pi to be used, so just round to 132.97)

If it took 25 hours to drain a 55,000 gallon pool, what was the flow rate through the drain pipe?
gallons/ hour?
Answer:2200 gallons an hour
Step-by-step explanation:
55,000 ÷ 25 = 2,200 gallons an hour
2,200 gallons per 1 hour
55,000÷25=2,200
if 2,200 gallons leaks out every one hour, after 25 hours 55,000 gallons would be gone.
What is the surface area of the piece of cheese?
A. 14.5 square inches
B. 29 square inches
C. 32. square inches
As you can see in the diagram, the triangular prism has the following faces:
1) Two triangular faces
2) Three rectangular faces.
Surface area is the SUM of the areas of all of the faces.
Let us find these faces one by one:
1.
As you know, the area of the triangle is:
[tex]\frac{1}{2}* base*height[/tex]
Since, the base = 6 inches, and height = 4 inches;
Therefore, The area of ONE triangle = (1/2) * 6 * 4 = 12 inches squared.
In triangular prism, there are two triangles, therefore,
Two triangular faces = 2 * 12 inches = 24 inches squared --- (A)
2.
Now let us find the areas of three rectangular faces...
Since, two of the three rectangular faces are the same, therefore, we would find the area of one rectangular face, and multiple the result with two to get the total area of two rectangular faces.
Area of one rectangular face = base * height.
Since, base = 0.5 inches, height = 5 inches, therefore,
Area of one rectangular face = 0.5 * 5 = 2.5 inches squared.
Now that we have one rectangular face, therefore,
Area of two rectangular faces = 2 * 2.5 = 5 inches squared.
The area of the third rectangular base = 6 * 0.5 = 3 inches squared
Therefore,
The area of the three rectangular faces = 5 + 3 = 8 inches squared --- (B)
Now add both "area of two triangular faces(A)" and "area of three rectangular faces(B)" to get the final surface area of the triangular prism.
Surface Area of the triangular prism = Area of Two Triangular faces + Area of Three Rectangular faces
Surface Area = 24 + 8 = 32 inches squared
The surface area of the triangular prism = 32 inches squared.

Answer:
90yrds^2
Step-by-step explanation:
First, let's find our area.
Area of a 2d rectangle is l(w). so 15(18) which in this case is 270ft.
Now that we have our area, we have to convert 270ft into yards.
A yard is equivalent to exactly 3ft. So let's use division to convert!
270/3 = 90.
Therefore, we need 90yrds^2 of carpet.
Answer:
2 or 3
Step-by-step explanation:
18 feet = 2 square yards
or if you
add 18 and 15 you get 33
33 feet = 3.6 square yards
The circumference of the hub cap of a tire is 80.89 centimeters. Find the area of this hub cap.
Answer:
1634.77
Step-by-step explanation:
2πr= circumference
80.89=2πr
80.89/ πr= r
r= 12.87
area= πr^2
area= 12.87 π^2
area= 1634.77
Answer:
520.89 cm²
Step-by-step explanation:
IN GIVEN QUESTION
The hubcap of the tire's circumference is 80.89 centimetres.
We must determine the radius of this hub cap, which we can do by using the circumference method to determine its area
now :
2πr = 80.89 cm
r = 80.89/ 2× 3.14
r = 12. 88 cm ( approx)
Area of hub cap = πr²
Area = 3.14 ×12.88² = 520.89 cm²

Which table of ordered pairs represents a proportional relationship?
Answer:
Therefore, the table of ordered pairs that represents a proportional relationship is Table 2.
Step-by-step explanation:
The ratio of Y to X is 1/-1 = -1, 3/-3 = -1, and 5/-5 = -1. Since the ratio is constant (-1), Table 2 represents a proportional relationship.
Answer:
B
Step-by-step explanation:
You cross multiply the numbers in each table. The table that has equal answers is proportional. In the table for choice B, you can tell the table is proportional since -1 x 3 = -3 x 1
A new bank customer with $3,000 wants to open a money market account. The bank is offering a simple interest rate of 1.9%. a. How much interest will the customer earn in 30 years? b. What will the account balance be after 30 years?
pls answer fast due in 10 minutes
a. To calculate the interest earned in 30 years, we can use the simple interest formula:
Simple interest = Principal * Rate * Time
Here, the principal (P) is $3,000, the rate (R) is 1.9%, and the time (T) is 30 years.
Simple interest = $3,000 * 0.019 * 30 = $1,710
Therefore, the customer will earn $1,710 in interest over 30 years.
b. To calculate the account balance after 30 years, we can add the interest earned to the principal:
Account balance = Principal + Interest
Account balance = $3,000 + $1,710 = $4,710
Therefore, the account balance will be $4,710 after 30 years.

Brittany gets 10 points in her book club for every book she reads, and she already has 50 points. She needs more than 190 points to receive the grand prize.
10x + 50 > 190
Which inequality represents the number of books Brittany needs to read to receive the grand prize? Select the inequality that contains the least number of books that Brittany can read and still receive the grand prize.
A. x > 14
B. x > 10
C. x > 140
D. x > 50
Answer:
A. x > 14
Step-by-step explanation:
Answer: A
Step-by-step explanation:
First, its important to realize that x= the number of books the reads. We put a 10 in front of the x because for every 1 books she reads, she receives 10 points. If she needs 190 points total, and already has 50 points, we then need to find how many points she needs to get to 190. To find this, we subtract 50 from 190, and are left with 140 points remaining to reach 190.
10x+50>190
-50 -50
10x>140
now that we know that 10x needs to be greater than 140, we can solve. We can divide both sides by 10 in order to find that x>14. She needs to read more than 14 books in order to earn the grand prize
[tex]\frac{10x > 140}{10}[/tex] = x>140
(URGENT, 40 POINTS!!!!!!)

Angle X + Angle 2x + 21 = 180. [ LINEAR PAIR ]
Angle 3x + 21 = 180
Angle 3x = 180 - 21 [ Transposing 21 over to RHS ] ( addition becomes subtraction)
Angle 3x = 159
Angle x = 159 ÷ 3. [ Transposing 3 over to RHS ] ( Multiplication becomes divison)
Angle x = 53°

Answer:
I believe it to be
yes for the first one
no for the second
yes for the last one
Answer:
Yes
No
Yes
Step-by-step explanation:
The first is yes because each person may work for different periods of time, thus resulting in many different answers!
Second is no because there are a strict, unchanging amount of hours in a day. There would be no variety in each answer.
The last is yes because each month has different conditions in which rainbows could occur. Like in December youll get little to no rainbows because theres no rainfall. But in july you can get many rainbows!
A spinner with five equal-sized colored sections is spun with the results shown in the table. Based on the experimental probability, predict the number of yellow results for 300 trials.
Red Orange Yellow Green Blue
16 15 20 14 15
A.75
B.60
C.40
D.20
Answer: 75
Step-by-step explanation:
Add the values given in the table
16+15+20+14+15 = 80
Yellow happens 20 times out of the 80 times total.
The experimental probability of yellow is 20/80 = 1/4 = 0.25 = 25%
If we do 300 trials, then we predict yellow to happen 0.25*300 = 75 times.
