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.

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 :)

Jake is renting a car from Hertz Car Rentals for a day.
It costs $85 plus $0.75 per mile driven.
Let C represent the cost of renting a car and m represent the number or miles driven.
Write a linear equation to represent the cost of renting a car for m miles.
Answer:
c=0.75m+85
Step-by-step explanation: m=slope and since its increasing by the same amount every mile $0.75 is the slope, and since it starts at $85 that would be the y-intercept. Hope this helps!
Explain whether this dilation is an enlargement or a reduction, and how you know. Triangle A B C is enlarged to triangle A prime B prime C prime.
Answer:
the answer is:
The dilation is an enlargement because the image, triangle A'B'C', is larger than the pre-image, triangle ABC.
Step-by-step explanation:
I got it right on edge
The dilation from triangle ABC to triangle A'B'C' is an enlargement
What is dilation?Dilation involves changing the size of a shape, figure or line
From the question, we understand that:
Triangle ABC is enlarged to form triangle A'B'C'
Also from the diagram, we can see that the side lengths of triangle A'B'C' are bigger than ABC
Hence, the dilation is an enlargement

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
I seagle is faster

8 people share 3 sub sandwiches equally. What fraction of a whole sub does each person get?
Answer: 2 2/3 (two and two thirds)
Each person get 6 2/3 fraction of a whole sub.
What is a fraction?Fractions represent the parts of a whole or collection of objects.
A fraction has two parts. The number on the top of the line is called the numerator and the number on the top of the line is called the denominator.
Now it is given that,
Number of people = 8
Number of sub sandwiches = 3
So, fraction of a whole sub does each person get = Number of people / Number of sub sandwiches
⇒ fraction of a whole sub does each person get = 8/3
or, fraction of a whole sub does each person get = 6 2/3
Thus, each person get 6 2/3 fraction of a whole sub.

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.

Also, please mark me as the brainliest and rate excellent.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]

I = -4
I = 3
0 1 = 1
o = 5
O r = -2
Answer:
Option A, Option D and Option E are correct options.
Step-by-step explanation:
We need to find solutions of the inequality: [tex]2x^2-1>6x[/tex]
We will check the options and see, which options satisfy the inequality.
Option A
x=-4
Put x=-4
[tex]2x^2-1>6x\\2(-4)^2-1>6(-4)\\2(16)-1>-24\\32-1>-24\\31>-24\:\:True[/tex]
So, x=-4 is the solution of inequality.
Option B
x=3
Put x=-3
[tex]2x^2-1>6x\\2(3)^2-1>6(3)\\2(9)-1>18\\18-1>18\\17>18\:\:False[/tex]
So, x=3 is not the solution of inequality.
Option C
x=1
Put x=1
[tex]2x^2-1>6x\\2(1)^2-1>6(1)\\2(1)-1>6\\2-1>6\\1>6\:\:False[/tex]
So, x=1 is not the solution of inequality.
Option D
x=5
Put x=5
[tex]2x^2-1>6x\\2(5)^2-1>6(5)\\2(25)-1>30\\50-1>30\\49>30\:\:True[/tex]
So, x=5 is the solution of inequality.
Option E
x=-2
Put x=-2
[tex]2x^2-1>6x\\2(-2)^2-1>6(-2)\\2(4)-1>-12\\8-1>-12\\7>-12\:\:True[/tex]
So, x=-2 is the solution of inequality.
So, Option A, Option D and Option E are correct options.
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
