( PLEASE ANSWER I WILL AWARD BRAINLIEST) A train is traveling at a constant speed and goes 7.5 kilometers in 6 minutes. At that rate:
How far does the train go in 1 minute?
How far does the train go in 100 minutes?
Answer:
#1-1.25
#2-125
Step-by-step explanation:
s=d/t
s=7.5/6
s=1.25
d=s*t
d=1.25*1
d=1.25
d=s*t
d=1.25*100
d=125
To even check my answer if you do 1.25*6 you get the distance 7.5 that was mentioned in the question.
Hope this helps! :) Plz mark as brainliest

A principal evenly distributes 6 reams of copy paper to 8 fifth-grade teachers How many reams of paper does each fifth-grade teacher receive? b. If there were twice as many reams of paper and half as many teachers, how would the amount each teacher receives change?
Answer:
a. 0.75 reams
b. The amount of reams received by each teacher would increase by 2.25 reams.
Step-by-step explanation:
Total reams of copy paper = 6
Number of fifth-grade teachers = 8
a. Number of reams collected by each teacher = [tex]\frac{number of reams}{number of teachers}[/tex]
= [tex]\frac{6}{8}[/tex]
= [tex]\frac{3}{4}[/tex]
= 0.75 reams
b. Twice as many reams of paper = 2 x 6
= 12
Half as many teachers = [tex]\frac{1}{2}[/tex] x 8
= 4
Number of reams collected by each teacher = [tex]\frac{12}{4}[/tex]
= 3 reams
The amount of reams received by each teacher would increase by;
3 - [tex]\frac{3}{4}[/tex]
= [tex]\frac{12 - 3}{4}[/tex]
= [tex]\frac{9}{4}[/tex]
= 2.25 reams
The amount of reams received by each teacher would increase by 2.25 reams.
John's library has 3 hardcover books for every 8 paperbacks. If he has 121 books in his library, how many of them are paperbacks. Will mark brainliest if correct. Pls show work.
Answer: 88
Step-by-step explanation:
1. Add 3 and 8 together
3 + 8 = 11
2. Divide 121 by 11
121/ 11 = 11
3. Multiply the amount of paperbacks in the stack of 11 books (8) by 11
11 x 8 = 88
88 Is your answer.

The Rodriguez family went out to dinner and the bill came to $35.85. They wanted to leave a 20% tip. What is the tip? What is the total amount the Rodriguez family spent at the restaurant?
Answer:
The tip is $7.17
Total amount spent is $43.02
Step-by-step explanation:
The bill is $35.85
The tip is 20%
You want to find 20% of $35.85 so multiply 35.85 by .2 (20% to decimal is .2)
35.85 multiplied by .2 gives you $7.17
So the tip is going to be $7.17
The total amount the family pays is the sum of the tip and the bill so
tip + bill = $7.17+$35.85 = $43.02
hope this helps
Answer:
total = $43.02
Step-by-step explanation:
for tip,
X = 20% of bill
X = 20/ 100 X $35.85
X = $ 7.17
For total amount,
total = bill + tip
= $35.85 + $7.17
= $43.02
Find the value of x in the triangle shown below.
x = ?
(this is another question)
Step-by-step explanation:
in a triangle = 180°
56 + 37 + x = 180
93 + x = 180
x = 180 - 93
x = 87
The population growth (in thousands) for Decatur can be represented by the expression 3x + 5 3 x + 261, where x represents the number of years since 2016. The population growth (in thousands) for neighboring Lithonia can be represented by the expression 4x - 5 2 x + 212, where x represents the numberof years since 2016. The governor of Georgia would like to know when the populations of the two towns will be equal.
Answer:
1967 or 2069
Step-by-step explanation:
To do this, you need to equal the expressions:
3x^2+53x+261=4x^2-52x+212
now, solve for y, when x=0:
-1(0)^2+53(0)+261=4(0)^2-52(0)+212
0+0+261=0-0+212
261=212
the difference is 49, so 49 years before or after 2016.

Carl and Cameron are at a pool carl dives in and touches the bottom of the pool 15 feet below the surface of the water Cameron standing on a diving platform 2 feet above the surface waiting for his turn what is the vertical distance between Carl's hand and Cameron feet
Answer:
21
Step-by-step explanation:
Answer:
17ft
Step-by-step explanation:
If Carl touches the bottom with his hand which is 15ft below the surface, and Cameron is standing 2 feet above the surface, all you have to do is add the two together. Cameron's feet are 2 feet above the surface, Carl's hand is 15ft below. 15 + 2 is 17.

When playing many games, players must roll a pair of dice and find the sum of the two numbers rolled. With two dice, there are 11 possible sums ranging from 2 through 12. What is the probability that a player will roll a sum of 11 on his first roll of two dice? Express your answer as a common fraction.
Answer:
[tex]Probability = \frac{1}{18}[/tex]
Step-by-step explanation:
Given
[tex]Dice = 2[/tex]
Required
Probability of getting sum of 11
First, we need to list out the sample space;
Represent the first dice with S1 and the second with S2
[tex]S_1 = \{1,2,3,4,5,6\}[/tex]
[tex]S_2 = \{1,2,3,4,5,6\}[/tex]
Represent the Sum of the outcome with S
So, the new sample space is the sum of outcome of S1 and S2
So, S is as follows:
[tex]S = \{2,3,4,5,6,7,3,4,5,6,7,8,4,5,6,7,8,9,5,6,7,8,9,10,6,7,8,9,10,11,7,8,9,10,11,12\}[/tex]
Represent the number of sample space with n(S)
[tex]n(S) = 36[/tex]
To determine the probability of outcome of 11, we need to list out the number of outcomes of 11.
Represent this with n(11)
From the sample space above,
[tex]n(11) = 2[/tex]
The required probability is then calculated as thus:
[tex]Probability = \frac{n(11)}{n(S)}[/tex]
[tex]Probability = \frac{2}{36}[/tex]
Simplify to the least term
[tex]Probability = \frac{1}{18}[/tex]
Home improvement charges $360 plus $12 per hour.Ace hardware charges $279 plus $15 per hour.Write and solve an equation for which the two cost would be the same
Answer:
360+12x=279+15x
The two costs would be the same when both companies charge 27 hours.
Step-by-step explanation:
From the information given, you need to find the number of hours where both companies charge the same and to do that, you can write an equation where Home Improvement cost is equal to Ace Hardware cost:
360+12x=279+15x, where x is the number of hours
Now, you can solve for x:
360-279=15x-12x
81=3x
x=81/3
x=27
According to this, the answer is that the two costs would be the same when both companies charge 27 hours.
A particular plant root grows 1.5 inches per month. How many centimeters is the plant root growing per month? (1 inch = 2.54 centimeters). 0.59 centimeters 1.69 centimeters 3.81 centimeters 4.04 centimeters
Answer:
The plant root grows 3.81 centimeters per month.
Step-by-step explanation:
From Physics, we remember that an inch equals 2.54 centimeters. Given that a particular plant root grows 1.5 inches per month, we proceed to make a quick conversion to calculate its value in centimeters per month:
[tex]x = 1.5\,\frac{in}{mo}\times \frac{2.54\,cm}{1\,in}[/tex]
[tex]x = 3.81\,\frac{cm}{mo}[/tex]
The plant root grows 3.81 centimeters per month.

Melissa was recording the heights of 4 flowers in her garden. The rose bush grew 12 inches in 1 month, the daisies grew 5 inches in 2 weeks, the tulips grew 8 inches in 3 weeks, and the daffodils grew 3 inches in 1 week. Which flower grew at the slowest rate?
Answer:
Daisies flower grows the slowest
Step-by-step explanation:
We are given;
Rate of growth of rose bush; 12 inches in 1 month.
1 month = 4 weeks.
Thus, we have; 12 inches in 4 weeks.
In 1 week, it grows; 12/4 = 3 inches per week
Rate of growth of daisies; 5 inches in 2 weeks. Thus, in 1 week, it grows by; 5/2 = 2.5 inches per week.
Rate of growth of tulips; 8 inches in 3 weeks. In one week, it grows by; 8/3 = 2.67 inches per week
Rate of growth of daffodils; 3 inches in 1 week = 3 inches per week
Looking at all the rates above, the slowest is 2.5 inches per week. This is for daisies.
