a) 10/-5, -12/2, 2/-3
b) they must have different signs
c) 10/5, -12/-2, 2/3
d) the must have the same sign
1) A quotient is negative is the divisor and the dividend have different signs
2) A quotient is positive if the divisor and the dividend have the same signs
3) no, sometimes the quotient can be a decimal or a fraction. example: 2/3, 5/2. counterexample: 10/5
4) The rules for dividing integers are similar to the rules for multiplying integers. The quotient is positive if the divisor and dividend have the same signs and negative if they have different signs.
5) gah, the phrasing is a bit odd. I'm afraid you're on your own here..
6 & 7) all three students that answered are correct
goodluck with your classwork/homework.

Answer: The blue car gets 26 2/3 mpg
The silver car gets 34 mpg
The silver car can travel farther on one gallon of gas. By about 7 1/3 miles.
Step-by-step explanation:
Divide miles by amount of gas.
Blue: 35 1/2 ÷ 1 1/2 = mpg
71/2 ÷ 3/2 => 71/2 × 2/3= 71/3
Simplify 26 2/3 mpg
Silver: 27 1/5 ÷ 4/5 =>136/5 × 5/4
136/4 Simplified = 34 mpg

Describe how to use the estimated difference to figure out if the difference in ERAs you found is reasonable.
Answer in 3 complete sentences.
Answer:
Perform the actual multiplication problem either by hand or with a calculator. In this example, students would multiply 21 times 31 to get 651. Subtract the smaller number from the larger one to check for reasonableness. In this example, you would subtract 600 from 651 to get 51.

Answer:
the table goes
9.25, 18.5, 27.75, 37, 46.25, 55.5, 64.75, 74, 83.5
1: greg makes 18.5 (or 18.50) an hour. I got that by taking the 64.75 we know and dividing it by 3.5.
2. if greg works 60 hours he will have made 1,110$. he made enough money for the lawn mower.
Answer:
Step-by-step explanation:
1. /
64.75 ÷ 3.5 =18.5$
Now you know haw much he earns in a hour
You complet the table by multiplying each time by 18.5
Greg earns 18.5$ in a hour
2. /
1387.5÷18.5 =75h
75h>60h
So yes they will buy him
Marcus invested $2000 in a bank account earning simple interest. The interest, I, he has after t years at an interest rate r is given by this equation.
l = 2000 rt
After 2 years, the total amount in the account was $2160. What was the annual interest rate?
Drag and drop an answer choice into each empty box below
The annual interest rate was
4%
8%
16%
40%
The value of the annual interest rate will be;
⇒ 4%
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division
Given that;
The invested amount = $2000
And , I = 2000 rt ….(i)
Now,
Since, The invested amount = $2000
⇒ Interest ‘I’ = $2160 - $2000
= $160
Time ‘t’ = 2 years
Substituting these values into;
⇒ 160 = (2000 x 2) r
⇒ r = 0.04
⇒ r = 4%
Thus, the interest r = 4%

A map uses a scale of 2 centimeters = 50 kilometers. The distance between various cities
on the map are given below. Find the actual distance between the cities.
9 cm
Answer:
225 kilometers
Step-by-step explanation:
Answer:
225 km

50 km / 2cm is the ratio. To make this easier, let's convert it to 25km per cm.
You are given 9 cm.
25(9) = 225.
A biking track has a length of 0.9 miles . How long is this in feet ?
First fill in the blank on the left side of the equation using one of the ratios. Then write your answer on the right side of the equation.
The biking track of 0.9 miles is 4752 feet long.
Length of the biking track = 0.9miles
What is the relation between mile and foot?We know that 1 mile equals 5280 feet or the length (in feet) is equal to the miles multiplied by 5,280.
The length of the biking track = 0.9miles
So, The length of the biking track(in feet) = 5280*0.9 feet
The length of the biking track(in feet) = 4752 feet.
Therefore, the biking track of 0.9 miles is 4752 feet long.

Can someone do an explanation on how to solve 15/20 - 3/20 in simplest form
Answer:
11/20
Step-by-step explanation:
Answer:
3/5
Step-by-step explanation:
Since both 15/20 and 3/20 have a common denominator you just subtract 3 from 15 and you get 12/20
Since both sides can be further divided by 4, you get 12÷4/20÷4 which equals
3/5 which cannot be further simplified
A cylindrical log has a length of 3 meters and a radius of 3/20 of a meter. how much space does the log occupy?
A. 9/20 PI m^3 B. 3/20 PI m^3 C. 27/400 PI m^3 D. 9/400 PI m^3
Answer:
0.212 sq-m
Step-by-step explanation:
(refer to attached)
Volume of a cylinder is given by
V = πr² h, where 3 is the radius and h is the height
in this case, h is given as the length of the cylinder of 3 m
r is given to be (3/20)m
hence,
V = πr² h
V = π(3/20)² (3)
V = π (9/400) (3)
V = π (27/400) (assuming π = 3.142)
V = 3.142 (27/400) = 0.212 sq-m
