Answer:
The only thing I can think of is -2.
Step-by-step explanation:
-9 + 7 = -2
I'm not sure if you wrote the questions or the answers wrong, but if I'm reading it right the answer should be -2, not 2. Unless you meant to write 9 + -7, in which case the answer would be 2.

Answer:
Step-by-step explanation:
3) diameter of penny = 19 mm
r = 19/2 = 9.5 mm
Area of penny = πr²
= 3.14 * 9.5 * 9.5
= 283.385
= 283.39 mm²
Diameter of nickel = 21 mm
r = 21/2 = 10.5 mm
Area of nickel = πr²
= 3.14 * 10.5 *10.5
= 346.185
= 346.19 mm²
346.19 - 283.39 = 62.8 mm²
Area of Canadian nickel is greater than Canadian penny by 32.6 mm²
4) r = 12 mm
Area of circle = πr²
= 3.14 * 12 * 12
= 452.16 mm²
5) r = 20 cm
Area of circle = πr²
= 3.14 * 20 * 20
= 1256 cm²
Convert 13 over 2 to a decimal using long division.
Answer:
6.5
Step-by-step explanation:
You divide.
So like 13 / 2 is 13 divided by 2 and is 6 remainder 1.
You can write this as 6 1/2.
1/2 is 0.5
So 13/2 is 6.5
A phone company has a monthly cellular plan where a customer pays a flat monthly fee and then a certain amount of money per minute used on the phone. If a customer uses 410 minutes, the monthly cost will be $71.50. If the customer uses 720 minutes, the monthly cost will be $118. Find a linear equation for the monthly cost of the cell plan as a function of x, the number of monthly minutes used.
Answer:
Linear equation for the monthly cost of the cell plan is [tex]10+0.15x[/tex]
Step-by-step explanation:
Let u denotes a flat monthly fee and v denotes amount charged per minute.
As the monthly cost is $71.50 if a customer uses 410 minutes,
[tex]71.50=u+410v[/tex] (i)
As the monthly cost is $118 if a customer uses 720 minutes,
[tex]118=u+720v[/tex] (ii)
Subtract (i) from (ii)
[tex]118-71.50=u+720v-u-410v\\46.5=310v\\v=\frac{46.5}{310}\\ v=0.15[/tex]
Put [tex]v=0.15[/tex] in (i)
[tex]71.50=u+410(0.15)\\71.50=u+61.5\\u=71.50-61.5\\u=10[/tex]
As x denotes the number of monthly minutes used,
linear equation for the monthly cost of the cell plan is [tex]10+0.15x[/tex]

Crystal baked 54 muffins for her family and friends. Her friends take 1/6 of the muffins. How many muffins does she have left? Of the muffins that she has left, her family took 2/5 of them. How many muffins did her family take? After her friends and family have taken their muffins, Crystal eats 1/3 of what is left. How many muffins did Crystal eat?
Answer:
she has 45 muffins left
her family took 18 muffins
crystal ate 9 muffins
Step-by-step explanation:
54 × 1/6 = 9
54 - 9 = 45
45 x 2/5 = 18
45 - 18 = 27
27 x 1/3 = 9
A bookstore marks up the price of a book by 40% of the cost from the publisher. Therefore, the bookstore's price to the student, P(x) (in $) after a 7.5% sales tax, is given by P(x) = 1.075(x + 0.40x), where x is the cost of the book from the publisher. Evaluate P(60) and interpret the meaning in the context of this problem
Answer:
This means that, when the price of book from publisher is $60, the bookstore will sell it $88 to the students.
Step-by-step explanation:
Solution:
The cost of book from publisher = 40%
Sales tax = 7.5%
Price of books to the student = p(x) = 1.075x + 0.40x
Where, x is cost of book.
P (60) =?
We know that,
P(x) = 1.075 + 0.40
= 1.475%
=148
Given, Cost of book, x = 60
P (60) = 148 – 60
= 88
This means that, when the price of book from publisher is $60, the bookstore will sell it $88 to the students.

The average weight of the top 5 fish at a fishing tournament was 13.3 pounds. Some of the
weights of the fish are shown in the table.
Answer:
15.4 lbs
Step-by-step explanation:
Since the average of the top five is 13.3 this says that:
total weight of all the fish / 5 = 13.3 lbs
Therefore, the total weight of all five fish is equal to:
13.3 * 5 = 66.5
With this number, I subtracted all the other weights and found that the missing weight was:
15.4lbs.
Therefore, Wayne S. had the biggest fish weighing 15.4lbs
Answer:
15.4
Step-by-step explanation:
(14.2 + 13.4 + 12.1 + 11.4 + X) / 5 = 13.3
(51.1 + X) / 5 = 13.3
Cross:
51.1 + X = 66.5
then X = 66.5 - 51.1
= 15.4

Sally and Anne went to the movies. They each purchased a drink. They also bought one popcorn and one veggie cup to share. Each woman's total is modeled with this expression: 9+1.34+1/2(3.50+1.74) How would you simplify the expression? Explain your steps.
Answer:
12.91
Step-by-step explanation:
We are told that Each woman's total is modeled with this expression:
9 + 1.34 + 1/2(3.50 + 1.74)
To solve this we will use the BODMAS acronym.
So the first operation will be to solve what's in the bracket to give;
9 + 1.34 + 1/2(5.14)
Let's now carryout the multiplication of the bracket to give;
9 + 1.34 + 2.57
Using the addition operation now gives us: 12.91
Answer: First, add the decimals in the parentheses. Next, multiply that number by 0.5. Finally, add all the decimal numbers.
Harper knows he is 100 yards from school. The map on his phone shows that the school is 1/3 inch from his current location. If Harper’s current location is 3 inches from home on the same map, how far is Harper from home?
Helpppp
Answer:
4 7/17 yeards or 4.412 yards approximately if the map shows the distance as 3 inches.
Step-by-step explanation:
The actual distance of the Harper from the school = 50 yards. According to the map, the distance from the school = 34 inches. We could say 34 inches represents 50 yards. So, 1 inch could be represented by 50/34 = 25/17 yards. In order to find the actual length of 3 inches in yards, we need to multiply 1 inches value of yards by 3.Therefore, 3 inches = 3* 25/17 = 75/17 = 4 7/17 yeards in decimals 4.412 yards approximately. Therefore, Harper from home is 4 7/17 yeards or 4.412 yards approximately if the map shows the distance as 3 inches.
The sum of two numbers is 4 times their difference. If one exceeds the other by 8, what are the numbers?
Answer:
12, 20
Step-by-step explanation:
Let the two numbers be x and y, where x > y
According to the given information:
x + y = 4(x - y)
x + y = 4x - 4y
y + 4y = 4x - x
5y = 3x
[tex] y = \frac{3}{5}x.... (1)[/tex]
Since, one number exceeds the other by 8.
[tex] \implies x = y + 8\\\\
\implies y = x - 8.....(2)\\\\[/tex]
From equations (1) & (2)
[tex]x - 8 = \frac{3}{5} x \\ \\ 5(x - 8) = 3x \\ \\ 5x - 40 = 3x \\ \\ 5x - 3x = 40 \\ \\ 2x = 40 \\ \\ x = \frac{40}{2} \\ \\ \huge \purple{ \boxed{\implies x = 20}} \\ \\ \implies \: y = x - 8 = 20 - 8 \\ \\ \huge \pink{ \boxed{ \implies \: y = 12}}[/tex]
