x² = 81 ⇒ x = √81 = ± 95.
x³ = 343 ⇒ x = ∛343 = 76.
x² = 1/100 ⇒ x = √1/100 = ± 1/10 = ± 0.17.
x² = 200 ⇒ x = √200 = 10√2 ≈ 14.14 ft1.28.

If the width of the parking lot is 83 m, what is its length?
Length of the parking lot: Im
(b) The perimeter of a rectangular pool is 352 m.
If the length of the pool is 97 m, what is its width?
width of the pool: Im
Answer:
A) Length = 94 m
B) Width = 79 m
Step-by-step explanation:
A)
The area of a parking lot is 7802 m²
Area = length x width
7802 = length x 83
length = 7802 ÷ 83
length = 94 m
b)
The perimeter of a pool is 353 m
Perimeter = 2(length + width)
352 = 2(97 + width)
352 = 194 + 2width
2width = 352 - 194
2width = 158
width = 158/2
width = 79 m

Wilmer went up the hill for xxx minutes at a speed of yyy kilometers per minute. Then he went down the same path at a speed of zzz kilometers per minute, and it took him www minutes to do it.
Write an equation that relates xxx, yyy, zzz, and www.
The equation that relates xxx, yyy, zzz, and www is xxxyyy = wwwzzz
Since Wilmer went up the hill for xxx minutes at a speed of yyy kilometeres per minute, the distance d he moves up the hill is d = speed × time = yyy × xxx = xxxyyy.
Also, Wilmer travels the same path at a speed of zzz kilometers per minute and it took him www minutes. So, the distance d' he moves down hill is d' = speed × time = zzz × www = wwwzzz.
Since the distance he moves up the hill equals the distance he moves down the hill, d = d'
So, xxxyyy = wwwzzz
So, the equation that relates xxx, yyy, zzz, and www is xxxyyy = wwwzzz

Answer:
80 boxes
Explanation:
15 goes into 20 4 times, so if 15 dollars = 20 boxes that would be 80 boxes of cookies she would have to sell.
15+15+15+15= 60

In training for a swim meet, Logan swam 750 meters in of an hour. His swimming partner, Mila, swam of Logan's distance in of an hour.

Compare Mila's and Logan’s swimming speeds. Show your work.
Is this your question?
In training for a swim meet, Logan swam 750 meters in 1/3 of an hour. His swimming partner, Mila, swam 2/3 of Logan's distance in 1/4 of an hour. (the question is What is Mila's average swimming speed?)
Answer:
Mila's average swimming speed is 34.44 m/min.
Logan's average speed is 2.25 kilometers per hour.
Step-by-step explanation:
Given:
In training for a swim meet, Logan swam 750 meters in 1/3 of an hour.
His swimming partner, Mila, swam 2/3 of Logan's
To Find:
What is Logan's average swimming Speed?
Solution:
The relationship between speed, distance, and time is easily remembered when you consider that speed is written in terms of units of distance per units of time. (miles per hour, or kilometers per hour, for example) "per" means "divided by".
[tex]\left[Speed=\frac{Distance}{Time} \right][/tex]
[tex]\left[speed = (750 m)/(1/3 h) = 2250 m/h = 2.25 km/h\right][/tex]
Logan's average speed is 2.25 kilometers per hour.
-------------------------------------------------------------------------------------------------------------
Given:
In training for a swim meet, Logan swam 750 meters in 1/3 of an hour.
His swimming partner, Mila, swam 2/3 of Logan's distance in 1/4 of an hour
To find:
What is Mila's average swimming speed?
Solution:
The distance swam by Logan = 750 m
The distance swam by Mila = 2/3 of Logan's distance = 2/3 x 750 = 2 x 250 = 500
The time taken by Mila to swim 500 m = 1/4 of an hour = 1/4 x 60 = 15 Minutes [since 1 hr = 60 mins]
We know the formula as:
[tex]\left[Speed=\frac{Distance}{Time} \right][/tex]
Now, substituting the values in the formula above to find the speed of swimming of Mila,
The average swimming speed of Mila = [tex]\frac{500m}{15mintues}[/tex][tex]=33.34m/min[/tex]
Therefore, Mila's average swimming speed is → 34.44 m/min.

in the right triangle, the legs have lengths 5 and 7 . Express the length of the hypotenuse in radical form?
Answer:
[tex]\sqrt{74}[/tex] units
Step-by-step explanation:
Hi there!
We can use the Pythagorean theorem to solve this question:
[tex]a^2+b^2=c^2[/tex] where a and b are the two legs and c is the hypotenuse
Plug in the two legs 5 and 7 and solve for c, the hypotenuse:
[tex]5^2+7^2=c^2\\25+49=c^2\\74=c^2\\c=\sqrt{74}[/tex]
Therefore, the length of the hypotenuse in radical form is [tex]\sqrt{74}[/tex] units.

The sum of three consecutive even integers is 642. What are the integers? (Show your work too please)
Answer:
212,214,216
Step-by-step explanation:
n+n+2+n+4=642
add the n's and 2 and 4
3n+6=642
subtract 6 from both sides
636 divided by 3
you get 212 then add 2 twice.
Answer:
212, 214, 216
Step-by-step explanation:
Basically you can divide 642 by 3 to find the average number of the 3. get You get 214, so that means 214 + 214 + 214 = 642
We need consecutive EVEN integers though, so you can take the one even BEFORE and then one even AFTER 214
This means 212 and 216 are used as they are 2 before and 2 after, so when added they still total 642.

Liam is setting up folding chairs for a meeting. If he arranges the chairs in 5 rows of the same length, he
has 5 chairs left over. If he arranges the chairs in 3 rows of that same length, he has 15 left over. How many
chairs does Liam have?
Liam has
chairs.
Answer:
30 Chairs
Step-by-step explanation:
I will solve this problem using algebra and try to explain in detail.
We can form two equations with the information given to us.
Firstly, 5 times a length of chairs (I will call this unknown length of chairs x), plus 5 left over chairs, equals the total number of chairs (I will call the total number of chairs y).
5x + 5 = y
Secondly, 3 times a length of chairs (I will call this unknown length of chairs x), plus 15 left over chairs, equals the total number of chairs (I will call the total number of chairs y).
3x + 15 = y
Since both equations are equal to y, they are equal to each other
5x + 5 = 3x + 15
Take 5 away from both sides of the equals, and take away 3x from both sides of the equals
5x - 3x = 15 - 5
2x = 10
Divide both sides by 2
x = 5 chairs
Put this back into either the first equation or the second to solve for y
3 (5) + 15 = y
15 + 15 = y
y = 30 chairs
a) (x+1)^3=
b) (2x +y)^3=
