Answer:
A
Step-by-step explanation:
Distance covered by Amy in one hour = 1/3 x 15 miles = 5 miles
Distance covered by John in one hour = 1/5 x 30 miles = 6miles
As a result, John would jog 1 mile (6-5) farther than Amy, the answer is A
Answer: John goes 1 mile further than Amy
Step-by-step explanation:
Figure out how far each person can go in an hour
Amy can go 1/3 of a mile in 1/15 of an hour- Multiple by 15 to see how far she can go in 1 hour
[tex]\frac{1}{3} *15= \frac{15}{3} = 5[/tex] so in 1 hour Amy can go 5 miles
John goes 1/5 of a mile in 1/30 of an hour- so multiple by 30 to see how far he goes in 1 hour
[tex]\frac{1}{5} * 30 = \frac{30}{5} = 6[/tex]
John goes 6 miles in an hour
So John goes 1 mile further than Amy (6-5)=1

O A. (x-4)(x + 4i)(x + 4i)
B. (x + 4)(x + 4i)(x + 4i)
C. (x + 4)(x + 4i)(x-4i)
O D. (x-4)(x + 4i)(x-4i)
Given:
Consider the given polynomial is:
[tex]x^3+4x^2+16x+64[/tex]
To find:
The complete factorization of the given polynomial.
Solution:
We have,
[tex]x^3+4x^2+16x+64[/tex]
Using grouping method, we get
[tex]=(x^3+4x^2)+(16x+64)[/tex]
[tex]=x^2(x+4)+16(x+4)[/tex]
[tex]=(x+4)(x^2+16)[/tex]
[tex]=(x+4)(x+4i)(x-4i)[/tex] [tex][\because x^2+y^2=(x+iy)(x-iy)][/tex]

5) Mario owns a plumbing business. He charges an hourly rate plus a onetime set up fee. His first job was 4 hours and he charged $450. His second job was 3 hours and he charged $675. If his set up fee is $150, how much does he charge per hour?
Answer:
Results are below.
Step-by-step explanation:
First, we need to calculate the variable income per job:
First job= 450 - 150= 300
Second job= 675 - 150= 525
Now, the hourly rate:
Hourly rate= total variable income / number of hours
First job= 300 / 4= $75
Second job= 525 / 3= $175
It is probably that the second job was 7 hours long. If not, he doesn't charge the same amount per hour
which equation is equivalent to 63-3(2-10x)=150
Answer:
D: 57 + 30x = 150
Step-by-step explanation:
63-3(2-10x)=150
63 - 6 + 30x = 150
57 + 30x = 150
James, Reed, Spencer and Larry have 912 cups of trail mix for their hike. If they each eat the same amount of trail mix, how many cups will each person eat?
Answer:
228 cups
Step-by-step explanation:
the cups each person will eat can be found by dividing the total number of trail by the number of people who went on the hike
total number of people on the hike = 4
total cups of trail = 912
912 / 4 = 228 cups

Answer:
GK=JK
Step-by-step explanation:
SSS congruency is side-side-side congruency. We are given that GH=JH and KH=KH, which are both sides.
For SSS, we need 3 pairs of congruent sides. We already have 2 pairs.
The options are:
<G=<J
<H=<H
GK=JK
the first two options, <G=<J and <H=<H are talking about congruent angles. We don't need to know about congruent angles for SSS
GK=JK is talking about a pair of congurent sides. Then, we would have 3 pairs of congruent sides, satisfying the criteria needed for SSS. Therefore, we must know that GK=JK.

What is -6x+4(-2x+8y)-2y+4
Answer:
-14x + 30y + 4
Step-by-step explanation:
-6x + 4(-2x + 8y) - 2y + 4
take out the parentheses
4(-2x + 8y) = -8x + 32y
-6x - 8x + 32y - 2y + 4
solve for the x's then y's
-6x - 8x = -14x
32y - 2y = 30y
you are done
-14x + 30y + 4

−2(x+8)+6=7(x−3) for x algebraically. If your answer is a fraction, write it in reduced, fractional form. Do NOT convert the answer to a decimal.
Answer:
x = 11/5
Step-by-step explanation:
-2x - 16 + 6 = 7x - 21
5x - 21 = -10
5x = 11
x = 11/5
Answer:
x = 11/9
Step-by-step explanation:
-2(x + 8 ) + 6 = 7(x - 3) {Use distributive property: a(b +c)= a*b +a*c) }
-2x + 8*(-2) + 6 = 7*x - 3*7
-2x - 16 +6 = 7x - 21 {add 2x to both sides}
-10 = 7x + 2x - 21
-10 = 9x - 21 {add 21 to both sides}
-10 + 21 = 9x
11 = 9x {divide both sides by 9)
11/9 = x

Andy buys a new car for $23,540. He estimates that the new car will decrease in value by about 5% each year. Which of the following functions best models this situation?
f(x)=23,540(1.05)xf of x is equal to 23 comma 540 times 1 point 0 5 to the x th power
f(x)=23,540(0.95)xf of x is equal to 23 comma 540 times 0 point 9 5 to the x th power
f(x)=−23,540(1.05)xf of x is equal to negative 23 comma 540 times 1 point 0 5 to the x th power
f(x)=−23,540(0.95)x
The function that best models the situation is f(x) = 23540(0.95)ˣ, where x is the number of years.
What is function?A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given that, Andy buys a new car for $23,540. He estimates that the new car will decrease in value by about 5% each year.
The depreciation rate =
A = P(1-r)ⁿ
Where, A = amount final
P = initial amount
r = rate and n = number of the years
Therefore,
The depreciation rate =
f(x) = 23540(1-0.05)ˣ
f(x) = 23540(0.95)ˣ
Hence, the function that best models the situation is f(x) = 23540(0.95)ˣ, where x is the number of years.
