That is the reason why when you are trying to calculate the area of a triangle you do the base x height divided by two or in half. If you printed out the triangle twice then cut it out and put the two together it would be a rectangle.
Find the mean of the following numbers:
8, 21, 10, 6, 7, 20
A.10
B.12
C.13
D.15
Add all the numbers up and divide by how many numbers there are.
8+21+10+6+7+20=72
72/6=12
Therefore, the answer is B, 12.
Answer:
B is the answer:)
Step-by-step explanation:
8 + 21+10+6+7+20= 72
72÷6= 12

3656.64 m^2 to nearest hundredth.
Step-by-step explanation:
Area = area of rectangle + area of a circle
The radius of the circle = 1/2 * 40 = 20.
Area = 40*60 + π*20^2
= 3656.64 m^2.
Find the area of the circle below. Use 3.14 for pi

Kirsten buys a puzzle collection for $27.83. She pays with one $20 bill and two $5 bills. Using the least number of coins and bills, what is Kirsten's change? Drag numbers to complete the table. Numbers may be used once, more than once, or not at all.
Answer:
Step-by-step explanation:
So the total she pays is 30 dollars (20+5+5). The puzzle amount was 27.83. Subtract 27.83 from 30 dollars to get her change.
$2.17
Therefore, you could use a 2-dollar bill (or 2 1-dollar bills), a dime (10 cents), 1 nickel (5 cents), and two pennies (1 cent each). This will amount to the total change.
Help, quickly if possible.

The sum of four consecutive odd numbers is -72. What are the four numbers?
Write a let statement (or statements).
Answer:
So the four consecutive odd integers are: 51 , 53 , 55 and 57
Step-by-step explanation:
I wish i can help
Answer:
- 15, - 17, - 19, - 21
Step-by-step explanation:
let the 4 consecutive odd numbers be
n , n + 2, n + 4, n + 6 ( that is 2 between each odd number ) , then
n + n + 2 + n + 4 + n + 6 = - 72
4n + 12 = - 72 ( subtract 12 from both sides )
4n = - 84 ( divide both sides by 4 )
n = - 21 , then
n + 2 = - 21 + 2 = - 19
n + 4 = - 21 + 4 = - 17
n + 6 = - 21 + 6 = - 15
The 4 numbers are - 15, - 17, - 19, - 21

Answer: 3.84 m
Step-by-step explanation: The biggest clue here is that the scale factor is 1:12.
1:12=32:[tex]x[/tex]
To find [tex]x[/tex], multiply 32 by 12. 32x12 is 384. You can't say the answer is 384, however, since the label for the actual water tower says "m" for meters instead of "cm" like for the model. 384 cm is equal to 3.84 m.
Hope this helped! ;)

Abby lives in a home worth $115,000. She has a loan of $98,000 and has a credit card balance of $2,300. She has a car that is worth 5,800. She also has a bank account with a balance of $900 and $300 in gift cards. What is Abby's net worth?
Please have step by step!!!
Answer:
$21,700
Step-by-step explanation:
$115,000 - 98,000
$115,000 - 98,000 = 17000
Credit Card Balance = Money owed
17000 - 2300
17000 - 2300 = 14700
Cars worth = +
14700 + 5800
14700 + 5800 = 20500
Bank Acc = +
20500 + 900
20500 + 900 = 21400
Gift Cards = +
21400 + 300 = 21700

After remodeling the circular deck, the Museum Board Members decided to also build a
circular fence around the existing playground for safety reasons. The diameter of the
entire circular fence is 102.8 feet, while the radius of the playground is 37.3 feet.
Determine the difference in areas of the two regions. Show your work and justify your
reasoning.
9514 1404 393
Answer:
3929 square feet
Step-by-step explanation:
The radius of the fence circle is half its diameter, so is 51.4 feet. The area of a circle is given by the formula ...
A = πr^2
The difference in areas of the two regions is found by subtracting the smaller area from the larger one. So, the difference in area between the fenced area of radius 51.4 feet and the playground area of radius 37.3 feet is ...
∆A = π(51.4^2 -37.3^2) = 1250.67π ≈ 3929 . . . square feet

The eggs of birds and other animals come in many different shapes and sizes. Eggs often have a shape that is nearly spherical. When this is true, you can use the formula for a sphere to find their volume. The green turtle lays eggs that are approximately spherical with an average diameter of 2.9 centimeters. Each turtle lays an average of 116 eggs at one time. Find the volume of one egg, rounding your answer to the nearest tenth of a cubic centimeter. Then find the total volume of these eggs, to the nearest tenth of a cubic centimeter.

Find the product of two monomials: 4ab X - 5ab
Answer:
-20a^2b^2
Step-by-step explanation:
4ab * -5ab we see the qu asks to multiply a negative with a positive
so we automatically know it will be a negative. and we know monomials become squared.
4 x -5 = -20
ab x ab = a^2 b^2
As a full sum.
4ab * -5ab = -20a^2 b^2
Let's say that xy=z. If zx=y, what would x, y, and z equal?
Answer:
[tex]x = 1[/tex]
[tex]y=z[/tex]
Step-by-step explanation:
[tex]xy = z\\zx = y[/tex]
Substitute [tex]z[/tex] and [tex]y[/tex] back into the equations.
[tex]xyx =y\\x^2y=y\\x^2=1\\x=\sqrt{1} = 1[/tex]
[tex]z(1) = y\\z=y[/tex]
We cannot find [tex]z[/tex] and [tex]y[/tex] as we don't have enough information.
