Answer:
Area = 64 cm² ; Perimeter = 32 cm
Step-by-step explanation:
Since we know that the side lengths of a square are all equal, this means that all 4 square lengths are 8 cm. Knowing that, we could simply square one of the side lengths to find the area:
8² = 64 cm²
To find the perimeter, just add all the side lengths. There are four sides to a square so we can just multiply the side length by 4:
8 · 4 = 32 cm

Jill weighs 15 lbs. Less than Ken. Pete weighs 50 lbs. More than Jill. Eddie weighs 18 lbs. Less than Pete. How much does each weight, if the sum of their weights is 597?
Answer:
Jill = 125lb
Pete = 175lb
Eddie = 157lb
Ken = 140lb
Step-by-step explanation:
Given
Represent Jill with J; Ken with K; Pete with P and Eddie with E
[tex]J = K - 15[/tex]
[tex]P = 50 +J[/tex]
[tex]E = P - 18[/tex]
[tex]J + K + P + E = 597[/tex]
Required
Determine the weight of each
Substitute 50 + J for P in [tex]E = P - 18[/tex]
[tex]E = 50 + J - 18[/tex]
[tex]E = J + 50 - 18[/tex]
[tex]E = J + 32[/tex]
Make K the subject in [tex]J = K - 15[/tex]
[tex]K = J + 15[/tex]
Substitute [tex]K = J + 15[/tex], [tex]E = J + 32[/tex], [tex]P = 50 +J[/tex] in [tex]J + K + P + E = 597[/tex]
[tex]J + J + 15 + 50 + J + J + 32 = 597[/tex]
Collect Like Terms
[tex]J + J +J + J = 597 - 32 - 50 - 15[/tex]
[tex]4J = 500[/tex]
[tex]J = 500/4[/tex]
[tex]J = 125lb[/tex]
Substitute 125 for J in [tex]P = 50 +J[/tex]
[tex]P = 50 + 125[/tex]
[tex]P = 175lb[/tex]
Substitute 175 for P in [tex]E = P - 18[/tex]
[tex]E = 175 - 18[/tex]
[tex]E = 157[/tex]
Substitute 125 for J in [tex]K = J + 15[/tex]
[tex]K = 125 + 15[/tex]
[tex]K = 140[/tex]
Plastic cups come in packages of 24 and straws come in packages of 20, whats the smallest number of each that could be bought so that you had the same amount of cups and straws? 200 240 120 480
Answer:
120
Step-by-step explanation:
No. of plastic cups = 24
No. of straws =20
We need to find the smallest number of each that could be bought so that you had the same amount of cups and straws.
Prime factrisation of 24 = 2×3×2×2
Prime factorisation of 20 = 2×5×2
LCM = 120
Hence, the smallest number of each type will be 120.

Rita used 3/4 cup of white sugar and 1/2
cup of brown sugar to make a cake. How
much sugar did she use in all?
We need to make the denominators equal for both fractions to figure out how much sugar was used in all.
3/4 + 1/2
We can multiply the numerator and the denominator by 1 for 3/4. We can multiply the numerator and the denominator by 2 for 1/2. Therefore, we will get 1.
3/4 + 1 = 1 3/4 OR 7/4
Answer is 7/4 or 1 3/4.

Answer:
negative
Step-by-step explanation:
right-to-left is positive
left-to-right is negative
Answer:
Negative slope.
Step-by-step explanation:
When you try to determine the type of slope a graph shows, the direction of the line is really important. When a slope is positive, the line goes up in the right direction like this /. When a slope is negative, the line goes down to the right like this \. Undefined is when the line goes straight up and down and 0 is when the graph is straight across like this -. Therefore the graph is negative. Hope this helps :)

Mischa and Ben's combined SAT score was 2290. Ben and Ashley's
combined score was 2530. Mischa and Ashley's combined score was
2660. Find each student's individual SAT score.
Answer:
Ashley=1450
Ben= 1080
Mischa= 1210
Step-by-step explanation:
M= Mischa
B= Ben
A= Ashley
M+B=2290
A+B=2530
M+A=2660
M-A= -240
so 2M = 2420, and M= 1210
Then
1210 + B = 2290
B= 1080
Then
1210 + A= 2660
A= 1450

A science teacher ordered $3980 worth of microscopes and dissection kits for the new science lab. A total of 38 microscopes and 47 dissection kits were ordered. A microscope costs four times as much as a dissection kit. Write a system of linear equations that represents this situation. What is the cost of each item?
Answer:
Cost of a kit is $20
cost of a microscope is $80
Step-by-step explanation:
Here, we want to write a set of equations and solve
Let the cost of a microscope be $m while the cost of a kit be $k
Total cost of 38 microscopes will be 38 * m = $38m
Total cost of 47 kits = 47 * k = $47k
The sum of these is $3980
That will be;
47k + 38m = 3980 ••••••(i)
A microscope cost 4 times a kit
Mathematically;
m = 4k •••••••••(ii)
Substitute ii into i
47k + 38(4k) = 3980
47k + 152k = 3980
199k = 3980
k = 3980/199
k = $20
Recall;
m = 4k
m = 4 * 20 = $80

The sum of two numbers is 40 and the difference is 16. What are the numbers?
Answer:
28 and 12
Step-by-step explanation:
The sum of two numbers is 40 and the difference is 16. What are the number? x+y=40 Substitute for x from above. (y+16)+y=40 Subtract 16 from each side.
The two numbers whose sum is 40 and difference is 16 are 28 and 12.
Let's denote the two numbers as x and y. We are given the following information:
x + y = 40 (equation 1)
x - y = 16 (equation 2)
To solve for x and y, we can use a method called elimination or substitution. Let's use the elimination method here.
Adding equation 1 and equation 2, we eliminate the y term:
(x + y) + (x - y) = 40 + 16
2x = 56
x = 28
Now we can substitute the value of x back into equation 1 to solve for y:
28 + y = 40
y = 40 - 28
y = 12
Therefore, the two numbers are 28 and 12.

A rectangular swimming pool is twice as long as it is wide. A small concrete sidewalk surrounds the pool and is a constant 2 feet wide. The total area of the pool and sidewalk is 160 square feet. Find the dimensions of the pool
Answer:
The dimensions of the pool are:
Width: 8.944 feet
Length: 17.888 feet
Step-by-step explanation:
From Geometry, the area of a rectangle ([tex]A[/tex]), measured in square feet, is determined by the following equations:
[tex]A = w\cdot l[/tex] (1)
Where:
[tex]w[/tex] - Width, measured in feet.
[tex]l[/tex] - Length, measured in feet.
If we know that [tex]w = x[/tex], [tex]l = 2\cdot x[/tex] and [tex]A = 160\,ft^{2}[/tex], then we get the following second order polynomial:
[tex]2\cdot x^{2}-160 = 0[/tex] (1)
And we solve the expression for [tex]x[/tex]:
[tex]2\cdot x^{2} = 160[/tex]
[tex]x^{2} = 80[/tex]
[tex]x = \sqrt{80}\,ft[/tex]
[tex]x \approx 8.944\,ft[/tex]
Then, the dimensions of the pool are, respectively:
[tex]w \approx 8.944\,ft[/tex] and [tex]l \approx 17.888\,ft[/tex]

an owl travels 8 1/3 miles in 3/4 hour and a seagull travels 12 1/2 miles in 2/3 an hour. Which animal is faster?
Answer: The seagull is faster
Step-by-step explanation:
An owl travels 8 1/3 miles in 3/4 hour. The miles per hour of the owl would be:
= 8 1/3 ÷ 3/4
= 25/3 ÷ 3/4
= 25/3 × 4/3
= 100/9
= 11 1/9 miles pee hour
A seagull travels 12 1/2 miles in 2/3 an hour. The miles per hour of the seagull would be:
=12 1/2 ÷ 2/3
= 25/2 ÷ 2/3
= 25/2 × 3/2
= 75/4
= 18 3/4 miles per hour
Based on the calculation above, the seagull is faster.
Answer:
11 1/9 miles per hour<---- owls speed
