Answer:
641.29
Step-by-step explanation:
100% = 903.23
1% = 903.23 ÷ 100 = 9.0323
71% = 9.0323 x 71 = 641.2933
Rounded to 2 decimal places =
641.2933 = 641.29
Answer:
641.29 m
Step-by-step explanation:
Convert "71%" to the decimal fraction 0.71.
Then multiply 903.23 m by this 0.71:
641.29 m

find the perimeter of these figures *
please*
Answer:
The perimeter of figure a is 44 inches, the perimeter of figure b is 72 inches.
Step-by-step explanation:
The sides of figure a is 8; 2; 3; 12; 2; 12; 3; 2, to get the perimeter, add all the sides together, which will be 8 + 2 * 2 + 3 * 2 + 12 * 2 = 8 + 4 + 6 + 24 = 12 + 30 = 42 inches. The sides of figure b is 3; 3; 3; 3; 13; 13; 5; 5; 5; 5; 7; 7, to get the perimeter, add all the sides together, which will be 3 * 4 + 13 * 2 + 5 * 4 + 7 * 2 = 12 + 26 + 20 + 14 = 32 + 40 = 72 inches.
Answer:
a) 44
2 + 8 + 2 + 8 + 12 + 12 = 44
b) 72
13 + 13 + 3 +3 +3 +3 +5 +5 +5 +5 +7 +7 = 72

Hi!! Please explain how you got the answer, thanks!! :))
Start out by finding the area of the square.
a = 4²
a = 16
Since all we have to look at is 1/4 of this square, multiply the area by 1/4.
(16)1/4
4
The area of the triangle is 4.
Now we need the area of the circle.
a = πr²
Sub: a = π(2)²
a = π(4)
Since the portion of the circle that covers the triangle is 1/4 of the circle, subtract 1/4 of the area of the circle from the area of the circle.
a = 4 - 1/4(π(4))
a = 4 - 1/4π x 1
a = 4 - 1/4π
Now this is where it's supposed to go, considering the fact that π isn't given a value.
Normally, I'd use 3.14 for π, as the entire population would, and then it would be easy, but obviously that isn't an option.
Now this answer isn't up there, so my best option is to tell you it's most likely c, and I hope I'm right.

Last year, 85% of students participated in the school fundraiser. Using this data, what would be the BEST prediction of how many of the 320 students will participate in the fundraiser this year?
Answer:
C. 272
Step-by-step explanation:
Since we know 85% of the students participated last year we can assume the same amount will participate this year so to find the answer you simply do the total number of students (320) multiplied by 85% or .85 to get the best guess of how many students will participate this year.
what is 189 divided by 82???
2
8 2 | 1 8 9
1 6 4
2 5
Therefore, 180 divided by 82 = 2 with a remainder of 25
2 with a remainder of 25
Decimal form = 2.304878

Hi there!
Your job, at least on this triangle, is pretty simple. This is a 45-45-90 triangle.
Because this is a 45-45-90 triangle, both legs are 5. That leaves us to find the hypotenuse, x.
And a 45-45-90 triangle's hypotenuse is easy. You just take the measure of one of the legs, or 5 in this case, and stick a [tex]\sqrt{2\\}[/tex] right next to it. So your answer will be:
[tex]5\sqrt{2}[/tex]
I hope this helps! :)
Solve the equation 18 = 3 + 5x for x.
Answer:
[tex]18 = 3 + 5x \\ 5x = 18 - 3 \\ 5x = 15 \\ x = 3[/tex]
Answer:
X = 3
Step-by-step explanation:
18 - 3 = 15 and 3 x 5 = 15. However there is a way to check which would be doing 5 x 1 + 3 and 5 x 2 + 3 and so on and so on until you find your answer.
Estimate the solution of the system x+y=4 2x-y=6 by sketching a graph of each linear function. Then solve the system algebraically. Use your estimate to judge the reasonableness of your solution. The estimated solution is The algebraic solution is The solution is/is not reasonable because
Answer:
(10/3, 2/3)
Step-by-step explanation:
You may find it easier to write these two equations x+y=4 2x-y=6 in a column:
x+y=4
2x-y=6
Adding these together will eliminate y:
3x = 10. Then x = 10/3.
Substituting 10/3 for x in the first equation results in:
10/3 + y = 4
Clear fractions by multiplying all three terms by 3:
10 + 3y = 12
Then 3y = 2, and y = 2/3.
The solution is (10/3, 2/3)
Find the output, y, when the input, x, is 3.
Y=-5x+13
Answer:
y = -2
Step-by-step explanation:
y = -5x + 13
x = 3
y = -5(3) + 13
y = -15 + 13
y = -2
Answer:
Y = -2
Step-by-step explanation:
Y=-5x+13
Y =-5×3+13
Y= -15+13
Y = -2
Need helpppp helppp plzzzz 20 points
Answer: 7^3/7^6= 1/343
Step-by-step explanation: We move 7^-6 to a denominator because we cannot have a negative exponent in the numerator.
So it would be 7^3/7^6
Which then would be 7*7*7/7*7*7*7*7*7
Which would equal 343/117649
Simplify and you get 1/343

Michelle read 72 pages in 3 hours. What was her unit rate of pages read per hour?
Answer:
24 pages per hour
Step-by-step explanation:
72 pages = 3 hours
To find the rate of pages per hour, divide both sides by 3.
72/3 = 24, 3/3=1
24 pages per 1 hour, 24:1

6 plates and 5 cups cost 32.10 dollars. 7 plates and 6 cups cost 37.70 dollars. Each plate costs the same amount as the other plates, and each cup costs the same amount as the other cups. What is the cost of 1 plate? What is the cost of 1 cup?
Answer:
Plates are 2.80 Dollars and cups are 1.40 dollars
Step-by-step explanation:
Cups = c
Plates = p
6p + 5c = 23.80 ==> multiply by 6 ==> 36p + 30c = 142.80
7p + 6c = 28.00 ==> multiply by 5 ==> 35p + 30c = 140.00
Now use algebra to have the 30c be on one side and the rest on the other:
36p + 30c = 142.80 | -36p
30c = 142.80 - 36p
35p + 30c = 140.00 | -35p
30c = 140.00 - 35p
Now set them equal to each other about the 30c:
142.80 - 36p = 140.00 - 35p
Use algebra to solve for p:
142.80 - 36p = 140.00 - 35p | +36p
142.80 = 140.00 + p | - 140
2.80 = p
Go back to one of the "30c" equations and plug in the value for p:
30c = 140 - 35p
30c = 140 - 35(2.80)
30c = 140 - 98
30c = 42 | /30
c = 42/30
c = 1.4
Answer:
the cost of 1 plate $4.1
the cost of 1 cup $1.5
Step-by-step explanation:
6p + 5c = 32.10
7p + 6c= 37.70
Multiply the first by 6
Multiply the second by -5
and then ADD both
36p +30c = 192.6
-35p-30c = -188.5 (30c is cancelled)
p = 4.1
4.1(6) +5c = 32.10
24.6 +5c = 32.10
5c = 7.5
c= 1.5
1.5(5) =7.5
24.6 + 7.5 = 32.10
