Caroline and Chase are working on math homework. They decide to race to see who can finish first. Caroline is on number 12 and can solve 1 math problem in 1.5 minutes. Chase is on number 16 and can solve 1 math problem in 2 minutes. How many minutes will it take before they are on the same problem?
Answer:
It will take 24 minutes before they are on the same problem.
Step-by-step explanation:
Caroline is on number 12 and can solve 1 math problem in 1.5 minutes.
Per minute, she solved [tex]\frac{1}{1.5} = \frac{2}{3}[/tex] of a problem. So, after t minutes, she will be on the problem:
[tex]Ca(t) = 12 + \frac{2t}{3}[/tex]
Chase is on number 16 and can solve 1 math problem in 2 minutes.
Per minute, he solved [tex]\frac{1}{2}[/tex] of a problem. So, after t minutes, he will be on the problem:
[tex]Ch(t) = 16 + \frac{t}{2}[/tex]
How many minutes will it take before they are on the same problem?
This is t for which:
[tex]Ca(t) = Ch(t)[/tex]
So
[tex]12 + \frac{2t}{3} = 16 + \frac{t}{2}[/tex]
[tex]\frac{2t}{3} - \frac{t}{2} = 4[/tex]
[tex]\frac{4t-3t}{6} = 4[/tex]
[tex]\frac{t}{6} = 4[/tex]
[tex]t = 24[/tex]
It will take 24 minutes before they are on the same problem.

PLEASE HELPPPP! Emily is entering a bicycle race for charity. Her mother pledges $0.80 for every 0.5 mile she bikes. If Emily bikes 8 miles, how much will her mother donate?
Answer: $12.80
Step-by-step explanation:
:)
Answer:
$12.80 donated money if she bikes 8 miles. solved by finding out how much money she'll get in a mile add .80+.80 and get $1.60. this is way easier to set up equation instead if doing it by half mile. equation is y=1.6(x) // y is money donated, x is $1.60

The width of rectangle is the length minus 2 units. the area of the rectangle is 48 units. What is the width, units, of the rectangle?
Answer:
6
Step-by-step explanation:
W=L-2
A=L*W
48=L(L-2)
48=L^2-2L
You factor and then you get L=8
W=8-2=6

.) Which ordered pair shows an equivalent ratio
of pounds to dollars?
(24,30)
(20,25)
(25, 20)
(40.36)
Answer:
I think (25, 20) is your answer. hope it helps.
The equivalent ratio to (5, 4) is (25, 20). Therefore, option C is the correct answer.
What is the ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
The coordinates from graph are (5, 4), (10, 8), (15, 12) and (20, 16).
Equivalent ratios are ratios that can be simplified to the same value by dividing both the values by a common fraction.
Here,
(5, 4)=5(5, 4)=(25, 20)
(10, 8)=2(10, 8)=(20, 16)
(15, 12)=2(15, 12)=(30, 24)
(20, 16)
The equivalent ratio to (5, 4) is (25, 20). Therefore, option C is the correct answer.

4. A trapezoid with bases that measure 8 inches and 11 inches has a height of 3 inches. What is the area of the trapezoid?
Answer:
28.5
Step-by-step explanation:
Answer:
25.5 in^2
Step-by-step explanation:
the formula to calculate a trapezoid is (base 1 + base 2) * height/2

Answer:
A, 7d^2
Step-by-step explanation:
d times d = d^2
multiply 7
7d^2
Answer: choice A) [tex]7d^2[/tex]
This is the same as writing 7d^2
==================================================
Explanation:
When we add a number to itself repeatedly, we can use multiplication to shorten things. For example: 3+3+3+3 = 5*3 = 15. We have five copies of '3' being added, which explains the 5 times 3.
Extending this idea leads us to shortening repeated multiplications into exponentiations. In the case of [tex]7*d*d[/tex], we have two copies of 'd' being multiplied. We replace [tex]d*d[/tex] with [tex]d^2[/tex] which is the same as d^2. The ^ symbol means "exponent".
The exponent (2) tells us how many copies of the base (the term d) we multiply out.
Another example would be [tex]d^3 = d*d*d[/tex]
So that's why [tex]7*d*d = 7d^2[/tex]

12 : 50 : :18: ? what is the answer?
Answer:
6:25:9
Step-by-step explanation:
12:50:18
6:25:9
I think the question is asking for the ratio to be simplified, if so then that's what the answer is.
Answer:
75
Step-by-step explanation:
12 : 50 :: 18 : x
In proportion, Product of extremes = Product of means
12 * x = 50*18
[tex]x =\frac{50*18}{12}=\frac{50*3}{2}[/tex]
x = 25 * 3 = 75
