Lee can type 1 1/3 pages every 15 minutes. How many hours does it take him to type 10 2/3 pages? Complete the rate table to solve the proportion.
pages---> 4/3=32/3
hours---> 1/4 = x
Lee can type 10 2/3 pages in _________ hours.
a. 1 3/4
b. 2
c. 2 1/4
d. 2 1/2
Answers
Answer:
First, we know that:
1 1/3 = 4/3
10 2/3 = 32/3
15 minutes = 0.25 hours
Let's imagine that x (hours) is the time it takes Lee to type 32/3 pages.
From the information, we can tell that:
Lee can type:
4/3 pages in 0.25 hours
32/4 pages in x hours
So x should be:
x = (32/4 . 0.25)/4/3 = 2 (hours)
So it takes Lee 2 hours ro type 10 2/3 pages

Eve drinks 3/16 gallon of milk each day. How many days will it take Eve to drink 3 gallons of milk?
Answers
18 days
Step-by-step explanation:
3/16 x 6 = 1 2/16 x 3 = 3 6/16
6 x 3 = 18
Step-by-step explanation:
Since Eve takes 3/16 gallon of milk each day,
1 day = 3/16 gallon
x days = 3 gallons
Cross-multiply
3/16x = 3
3/16x÷3/16 = 3/3/16
Reciprocate
x = 3 × 16/3
x = 16 gallons

Rhett decides to build a square room for his movie and music collection. If the area of the room is 16x2 − 24x + 9 square feet, what is the length of one side of the room?
(4x + 3) feet
(16x + 3) feet
(16x − 3) feet
(4x − 3) feet
Answers
Answer:
16x^2 - (12+12)x + 9
16x^2 -12x -12x +9
4x(4x-3)-3(4x-3)
(4x-3)(4x-3)

I believe it is that hopefully you don't need work I'm to lazy.
Answer: A and D
Step-by-step explanation:
**REFERENCE**
Variable term: An x term, or a number with an x beside it, like 5x, 3x, 9x, etc.
Constant: A number with no letter beside it, like 5, 3, 10, and 1.
***
________
There are 2 ways to answer this. One is to solve all the equations, but another is to remember 3 simple rules.
1. For an equation to have one solution, they must have different variable terms and different constant terms.
- Example: 2x+12= 3x+15. The variable terms, 2x and 3x are ddifferent, and 12 and 15, the constants, are different as well.
2. For an equation to have no solutions, they must have the same variables on both sides, but different constants.
- Example: 2x+12=2x+9. The variables, 2x, are the same, but the constants, 12 and 9, are obviously different.
3. For an equation to have infinite solutions, both the variable and the constant terms must be the same on both sides.
- An example of an equation with infinite solutions is 2x+12=2x+12. The variable terms, 2x, are the same, and the constant term, 12, is also the same on both sides,
That being said, let's look at the 4 answer choices and determine how many solutions they have.
A. -5x+12=-12x-12
Rearranged for context: 12-5x= -12-12x
Variable terms: -5x and -12x. The variable terms are different.
Constant terms: 12 and -12. The constant terms are different
In option A, the variable and the constant terms are different. therefore it has 1 solution. A is correct.
B. -5x+12=5x+12
Rearranged for context: 12-5x=12+5x
Variable terms: -5x and 5x. They are different
Constant terms: 12 and 12. They are the same.
In option B, the variable terms are different but the constant terms are the same. This one is very confusing but since they don't have BOTH different variables and constants, I'll just assume that it doesn't have 1 solution.
C. -5x+12=-5x-12
Variable terms: -5x and -5x. SAME VARIABLES
Constant terms: 12 and -12. DIFFERENT CONSTANTS
No solutions
D. -5x+12=5x-5
Variables: -5x and 5x
Constants: 12 and -5
BOTH DIFFERENT
1 SOLUTION
D is correct.

Suppose that the values of x, y, and z are given by x=2/3 y=5/7 z= -11/3 What is xy/z
Answers
Answer:
The answer is -10/77 .
Step-by-step explanation:
In order to find the value of xy/z, you have to substitute the value of x, y and z into the expression :
\( \frac{xy}{z} = xy \div z\)
\(( \frac{2}{3} \times \frac{5}{7}) \div - \frac{11}{3} \)
\( = \frac{10}{21} \times - \frac{3}{11} \)
\( = \frac{10}{7} \times - \frac{1}{11} \)
\( = - \frac{10}{77} \)
solve each equation for the given variable
xy = k;y
a = 2/b + 3c; c

y=k/x

Answers
Answer:
Filling the chart to estimate the amount of each type of food that each family will receive is as follows:
Rounded Food Items and Families:
Food Item Number of Pounds Number of Families Estimated
Rounded Receiving Item Receiving
Chicken rolls 113 10 11.3

Green bean 19 11 1.7
Casserole 5 3 1.7
What is an estimate?
An estimate is a rough calculation based on available information or rounded-off data.
Estimates are made to enable quick decisions without knowing complete details.
For this estimate, we used the division operation to obtain the quotients that should be the share of receiving families from each food category.
Original Data:
Food Item Number of Pounds Number of Families
Available Receiving Item
Chicken rolls 113.4 9
Mashed potatoes 6.6 12
Corn 28.5 10
Green bean 18.92 11
Casserole 5.37 3
Thus, as much as possible, some pounds of food items have been rounded to enable the estimate to be produced.

Is Figure BBB a scale copy of Figure AAA?
Answers
Reason - if the scale factor of a and b was 2, the dimensions of a would be 4, 7.2 and 10 not the ones present on A
The ratios of corresponding side lengths are not equal.
Therefore, Figure B is not a scale copy of Figure A.
Here, we have to determine if Figure B is a scale copy of Figure A, we need to compare the corresponding sides of the two triangles and check if the ratios of their side lengths are equal.
Figure A has side lengths: 3.6, 2, and 5.
Figure B has side lengths: 8.9, 4, and 11.3.
Let's check if the ratios of corresponding side lengths are equal:
Ratio of corresponding side lengths of A and B:
3.6 / 8.9 ≈ 0.4045
2 / 4 = 0.5
5 / 11.3 ≈ 0.4425
The ratios of corresponding side lengths are not equal.
Therefore, Figure B is not a scale copy of Figure A.
In order for two triangles to be scale copies of each other, all corresponding side lengths must have the same ratio.
Since the ratios of side lengths in Figure A and Figure B are not equal, they are not scale copies of each other.
