A jet flies 175 miles in 7 minutes. How far will the jet fly in 85 minutes?
Given:
A jet flies 175 miles in 7 minutes.
To find:
How far will the jet fly in 85 minutes?
Solution:
According to the given information,
Distance covered by the jet in 7 minutes = 175 miles
Using this, we get
Distance covered by the jet in 1 minutes = [tex]\dfrac{175}{7}[/tex] miles
Distance covered by the jet in 1 minutes = [tex]25[/tex] miles
Now,
Distance covered by the jet in 85 minutes = [tex]85\times 25[/tex] miles
Distance covered by the jet in 85 minutes = [tex]2125[/tex] miles
Therefore, the jet flies 2125 miles in 85 minutes.

One number is 16 more than another number. The two numbers have a sum of 120. Which system of equations could you use to find the two numbers?
A)y=x – 16
y=x + 120
B)y=x + 16
y = x + 120
C)y=x - 16
y=x – 120
D)y= x - 16
y = -x + 120
Answer: D)y= x - 16
y = -x + 120
Step-by-step explanation:
Let the two numbers be x and y
such that if one number is x , the other number y
Let x be the number which is 16 more than another number , so that it can be expressed as
x= y+16 which can also be written as
y= x - 16
Also, if the two numbers have a sum of 120, then it can be represented as
x+y=120 or
y = -x + 120
Therefore system of equations to find the two numbers are
D)y= x - 16
y = -x + 120

Solve the proportion
2/r = 12/18
Answer:
r=3
Step-by-step explanation:
Divide the numbers
2/r=12/18
2/r=2/3
Multiply all terms by the same value to eliminate fraction denominators
rx2/r=rx2/3
simplify
2=2r/3
multiply all terms by the same value to eliminate fraction denominators again
3x2=3x2r/3
simplify
6=2r
divide both sides if the equation by the same term
6/2=2r/2
r=3

12x - 5y = –20
y=x+4
2 =
Y=
Answer:
Solution :
{x,y} = {0/14261512,4}
Step-by-step explanation:
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = x + 4
// Plug this in for variable y in equation [1]
[1] 12x - 5•(x +4) = -20
[1] 7x = 0
// Solve equation [1] for the variable x
[1] 7x = 0
[1] x = 0
// By now we know this much :
x = 0
y = x+4
// Use the x value to solve for y
y = (-0/14261512)+4 = 4

Kimberly has 3.25 kilograms of flour in a container. She adds 45 grams of flour to the container. How many kilograms of flour does she have now?
Answer:
3.295 Kilograms of flour
Step-by-step explanation:
Kimberly has 3.25 kilograms of flour in a container. She adds 45 grams of flour to the container. How many kilograms of flour does she have now?
Kimberly has 3.25 kilograms of flour in a container.
She adds 45 grams of flour to the container.
We convert 45 grams to kilograms
1 gram = 0.001 kilogram
45 grams = x
Cross Multiply
x = 45 × 0.001 kilogram
x = 0.045 kilograms
The kilograms of flour she has now is calculated as:
Number of kilograms of flour in the container + Number of kilograms of Flour just added
= 3.25 kilograms + 0.045 kilograms
= 3.295 Kilograms of flour
Steve invests $1,800 in an account that earns 3.7% annual interest, compounded continuously. What is the value of the account after 10 years? Round your answer to the nearest dollar. A. about $2,466 B. about $2,589 C. about $2,601 D. about $2,606
Answer:
B. about $2,589
Step-by-step explanation:
Given data
P=$1,800
R= 3.7%
T=10years
The expression for the compound interest is given as
A= P(1+r)^t
substitute
A= 1800(1+0.037)^10
A= 1800(1.037)^10
A=1800*1.43809495884
A=$2588.570
Hence the answer is B. about $2,589
