PLEASE HURRY: On Monday, Florencia's hair was h centimeters long. She got a haircut on Tuesday, so her hair was only 75% of
the length it was on Monday.
Which of the following expressions could represent how many centimeters long Florencia's hair was after the
haircut?
Chose 2 answers:
h(1 - 0.75)
(1 - 75/100)h
3/4h
0.75h
1/4h
Answer:
It seems that you are trying to find the length of hair of Florencia on Tuesday.
Given that length of the hair of Florencia on Monday = h centimeters
On Tuesday, she got hair cut.
So new length of the hair of Florencia on Tuesday = 75% of Monday value
= 75% of (h)
= 0.75* (h)
= 0.75h
Hence final answer is the length of the hair of Florencia on Tuesday is ( 0.75h ) centimeters.
Answer:
3/4h and 0.75h

Shirts are on sale for 30% off. The original price of one shirt is $15. What is the total cost, in dollars, of 2 of these shirts at the sale price, including a 7% sales tax?
Answer:
I pretty sure the answer is $22.47
Step-by-step explanation:
15+15=30-30%=21+7%=22.47
Answer:
Hi ! The answer to your question would be $23.54
Step-by-step explanation:
30% off of $15 would bring you to $10.50, if you add $10.50 twice u would get $21. The 7% sales tax would be $2.54, adding that to $21 you get $23.54
The graph represents the number of bike paths planned for the cities of Nashville and Houston. The number of paths to be built in Houston is modeled by y = 4(2)x, and the number planned for Nashville is modeled by y = 4x. According to the graph, which statement is true about this situation? A) The number of paths planned for Nashville is increasing exponentially. B) The number of paths planned for Houston is represented by the green line. C) The number of paths planned for Nashville is represented by the green line. D) The number of paths planned for Nashville will more than likely exceed the paths in Houston as the value of x increases.
Answer:
C
Step-by-step explanation:
Answer:
C. The number of paths planned for Nashville is represented by the green line.
Step-by-step explanation:
Nashville is y=4x, so if you graph that in desmos, you will see the line for Nashville is the same as the green line in the question.

Answer:
41 degrees
Step-by-step explanation:
All three angles in a triangle must add up to 180 degrees. The picture already tells you that B is 63 degrees. This means A and C should both add up 117 degrees. If A is 2x+8 and B is x+7, then A+B is 3x+15. This means that 3x+15 is equal to 117 degrees.
3x + 15 = 1173x = 117 - 153x = 102x = 102/3x = 34Now that we know that x is 34, we plug it in. X + 7 becomes 34 + 7 degrees which is equal to 41 degrees.

If the pointer in the figure is spun twice, find the probability that the pointer lands on yellow (Y) both spins.
Answer:
0.25
Step-by-step explanation:
Well assuming the result of the spin is uniformely random, the yellow area will come up 1/2 of the time (because it takes up 1/2 of the figure).
If it needs to land on yellow both times in two spins, we can take it step by step.
The probability it lands on yellow after the first spin is 0.5
The probability it lands on yellow and then lands on yellow again is 0.5 * 0.5 = 0.25
Think of both spins as 50% yellow, 50% non-yellow
We have 4 options
yellow, yellow
yellow, non-yellow
non-yellow, yellow
non-yellow, non-yellow
Each option is equally probable, so the probability of "yellow, yellow" is 0.25
What is the remainder in the synthetic division problem below?
1|4 6 -3
A. 3
B. 7
C. 5
D. 9
The correct option is (b) i.e. In the given synthetic division, the remainder will be 7.
What is Remainder ?
The remainder is what "remains" after an activity is finished, as its name implies. In mathematics, it is impossible to divide 17 by 3 precisely. The leftover after division is the number 2, which is set aside.
Given : 1 | 4 6 -3
If we solve it further, we get
1 | 4 6 -3
| 4 10
| 4 10 7
Steps :
firstly we will write 4 as it is .
we will multiply 1 by 4 and write it in the second place, then we will add 6 and 4.
Similarly, we will multiply 1 by 10 and write it in the third place, then we will add -3 and 10 and finally get 7 as residual.
here, after solving, we get 7 in the end which is set aside.
So, the remainder will be 7.
Hence, the correct option is (b).

The sum of the numbers 13 + 13 + 13 is 39.
What is Addition?Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.
The process of doing addition is also called as finding the sum.
Given expression is,
13 + 13 + 13
Here 13 is added to itself three times.
When 13 added to 13, we get 13 + 13 = 26
Again if we add the number 13 to 26, we get 13 + 26 = 39
13 + 13 + 13
= 26 + 13
= 39
This can also be written in the form of multiplication as 3 × 13, which is also equal to 39.
Hence the number 13 added to itself three times gives 39.

what is the equation of the given line ( 1,5) and (3,5)
A.)Y=5
B.)X=3
C.)Y=3
D.)X=1
Answer:
A) y = 5
Step-by-step explanation:
Points: (1, 5) and (3, 5)
Slope:
m=(y2-y1)/(x2-x1)
m=(5-5)/(3-1)
m=0/2
m = 0
Since 0 is the slope, that means there's no slope.
y - y1 = m(x - x1)
y - 5 = 0(x - 1)
y - 5 = 0
y = 5

one solution: {0,-3)
one solution: (1.-4)
Answer:
one solution: (1.-4)
Step-by-step explanation:
y = 2x - 6...... (1)
y = -x-3......(2)
Plug y = -x-3 in equation (1)
2x - 6 = - x - 3
2x + x = 6 - 3
3x = 3
x = 3/3
x = 1
Plug x = 1 in equation (2)
y = - 1 - 3
y = - 4
(x, y) = (1, - 4)

If the buses run on schedule, when is the next time a red line and a blue line bus will leave together? Show your work.
Answer:
So the next time they will leave together is 4:24 pm
Step-by-step explanation:
Since both the buses left at 4 pm and red line bus leaves every 6minutes and blue line bus leaves every 8 minutes they next time they leave together can be found by taking the L.C. M of 6 and 8.
The L.C. M is found by multiplying all the factors and chosing one which common in both numbers.
Factors of 6 = 2*3
Factors of 8= 2*2*2
In these numbers 2 is common in both.The rest of the numbers( 2*2*3 )are multiplied with the the common 2 to get the L.C.M
L.C.M= 2*2*2*3= 24 minutes
So the next time they will leave together is 4:24 pm
