B. 0.75
C. 1.250
D. 1.250 -1.25
Answer:
1.25c
Step-by-step explanation:
Given that :
Original cost of candy = c
Markup percentage = 25%

Marked up price = 1.25c
The students at view side elementary school had a read a thon the teachers kept track of how many books the students in each grade level read estimate the total number of books the students read round each number to the nearest hundred to help you find your answer
Kindergarten 247, first grade 385 , second grade 1347 and third grade 1549
Answer:
Estimate = 3400 books
Step-by-step explanation:
Given that:
Books read by students.
Kindergarten 247
First grade 385
Second grade 1347
Third grade 1549
We have to round the each number to nearest hundred.
247 rounded to the nearest hundred is 200.
385 rounded is 400
1347 rounded is 1300
1549 rounded is 1500
Total = 200 + 400 + 1300 + 1500 = 3400
Hence,
Estimate = 3400 books

Under her cell phone plan, Lily pays a flat cost of $55.50 per month and $4 per
gigabyte. She wants to keep her bill at $63.10 per month. Write and solve an equation
which can be used to determine x, the number of gigabytes of data Lily can use while
staying within her budget.
equation:
answer x=
Answer:
Equation : y = 4x + 55.50
x = 1.9 gigabytes
Step-by-step explanation:
Given that:
Flat fee per month = $55.50
Cost per gigabyte = $4
Let,
x be the number of gigabytes.
y be the total cost
y = 4x + 55.50
Lily wants to keep her bill $63.10
63.10 = 4x + 55.50
63.10 - 55.50 = 4x
4x = 7.60
Dividing both sides by 4
[tex]\frac{4x}{4} = \frac{7.60}{4}\\x=1.9[/tex]
Hence,
Equation : y = 4x + 55.50
x = 1.9 gigabytes
Answer:
Equation: 4x+55.5=63.1
Answer: x=1.9
Would you be breaking the speed limit in a 40 mi/h zone if you were traveling at 60km/h?
Since 40 mi/h is greater than 60 km/h. Therefore, 60 km/h is not breaking the speed limit given.
We need to check if would you be breaking the speed limit in a 40 mi/h zone if you were travelling at 60 km/h.
What is the speed?The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).
To check whether the speeds are the same, make their units the same.
As we know, 1 mile = 1.60934 km
So, 40 miles = 64.3736
≈64
Then, the speed =64 mile/h
Since 40 mi/h is greater than 60 km/h. Therefore, 60 km/h is not breaking the speed limit given.

James and Bethany Morrison are celebrating their 10th anniversary by having a reception at a local reception hall. They have budgeted $3500 for the reception. If the reception hall charges a $50 cleanup fee plus $34 per person find the greatest number of people that they may invite and still have within their budget.
Answer: See Below
Step-by-step explanation:
Create the equation:
$34 times the number of people plus the $50 cleaning fee has to be less than or equal to $3500
Or
34p + 50 <= 3500
34p <= 3450
p <= 101.470588....
We can have a part of a person attending the reception so we have to drop the remainder/decimal. Therefore the most amount of people that can attend the party and stay within budget is 101.

[tex]y = mx + b[/tex]
where m = slope and b = y-intercept.
What we have to do is to make the y-term as the subject of equation.
[tex]9x - 3y = 15 \\ 9x - 15 = 3y \\ \frac{9x - 15}{3} = y[/tex]
Simplify[tex] \frac{9x}{3} - \frac{15}{3} = y \\ 3x - 5 = y \\ y = 3x - 5[/tex]
From y = mx+b, the slope is 3.

Answer:
Not similar
Step-by-step explanation:
For two triangles to be similar , their sides should be in the same ratio. Here the sides are ,
First ∆ = 5 , 5 & 3 Second ∆ = 6 , 6 & 4Ratio of first sides :-
= 6/5 = 1.2
Ratio of second sides :-
= 6/5 = 1.2
Ratio of third sides :-
= 4/3 = 1.33
Since the ratio of all three sides are not same , Hence the two triangles are not similar.
Hence the two triangles are not similar .Solve for a and b. 40 30 5

Arthur's dog, Shep, had to go on a diet. After three months of dieting, Shep had lost 16% of his weight, which was 24 pounds. How much did Shep weigh before he was put on a diet?
Answer: 150 pounds
Step-by-step explanation:
Let her initial weight be represented by x.
Since Shep had lost 16% of his weight, which was 24 pounds. Shep weight before he was put on a diet would be:
16% × x = 24
0.16 × x = 24
0.16x = 24
x = 24/0.16
x = 150 pounds
