Answer:
How to Calculate a Rate. "Rate" simply means the number of things per some other number, usually 100 or 1,000 or some other multiple of 10. A percentage is a rate per 100. Infant mortality rates are calculated per 1,000.
Step-by-step explanation:
A pancake recipe require 1 2/3 cups of flour to make 20 pancakes and you have 9 cups of flour.
a. How many pancakes can you make with 1 cup of flour?
b. How many pancakes can you make with 9 cups of flour?
C. Do you have enough to make 100 pancakes? Explain
Quantity of flour needed to make 20 pancakes =
[tex] = 1 \frac{2}{3} \: [/tex]
[tex] = \frac{3 \times 1 + 2}{3} [/tex]
[tex] = \frac{5}{3} \: cups \: of \: flour[/tex]
Then , number of pancakes that can be made from 1 cup of floor :-
[tex]20 \div \frac{5}{3} [/tex]
[tex]20 \times \frac{3}{5} [/tex]
[tex] \frac{60}{5} [/tex]
[tex] = 12 \: pancakes[/tex] .
Therefore , 12 pancakes can be made from 1 cup of floor .
Solution (b) :-Number of pancakes that can be made with 1 cup of flour = 12 pancakes
Number of pancakes that can be made with 9 cups of flour :-
= 9 × 12
= 108 pancakes
Therefore , I can make 108 pancakes with 9 cups of flour .
Solution (c) :-Yes , I have enough flour to make 100 pancakes . I say this because :-
With one cup of flour I can make = 12 pancakes
With 9 cups of flour I can make =
= 9 × 12
= 108 pancakes
As I can make 108 pancakes with 9 cups of flour , I can conclude that I have enough flour to make 100 pancakes .

Please help me :)
Answer:
x= 12
Step-by-step explanation:
(9x -4)° +(5x +16)° = 180° (int. ∠s, L//m)
9x -4 +5x +16= 180
14x +12= 180 (simplify)
14x= 180 -12 (-12 on both sides)
14x= 168
x= 168 ÷14 (÷14 on both sides)
x= 12

Initially a pool contains 340 gallons of water. A hose is placed in the pool, and the water is turned on. The hose adds 5.2 gallons of water per minute. Write an equation to represent the total amount V of water in the pool in terms of x, the number of minutes the hose has been on.
Answer: Amount of water that is turned in a minute is 5.2d. Given the fact that initially was 350 gallons of water everything you pour needs to be added to the initial amount. So the answer is V(x) = 350 + 5.2x

Wayne is hanging a string of lights 45 feet long around the 3 sides of his rectangular patio, which is adjacent to his house. The length of his patio, the side along the house, is 5 feet longer than 2 times its width. Find the length and width of the patio.
Answer:
45=2w+L and L=2w+5
45=2w+L 45=2w+(2w+5)
45=4w+5
40=4w
10=w
L=2w+5 L=2(10)+5
L=20+5
L=25
The length of the patio is 25 feet and the width of one side of the patio is 10 feet. Because there are two width sides and one length side, this all adds up to be 45 feet long.

Complete the table of values to find the solutions of the equation -x + y = 6.
Answer:
Answer:
X l Y
-2 l 4
-1 l 5
0 l 6
1 l 7
2 l 8
Step-by-step explanation:
X l Y
-2 l - (-2) + y =6 => y = 6 - 2=> y = 4
-1 l - (-1) + y =6 => y = 6 - 1=> y = 5
0 l - (0) + y =6 => y = 6 + 0=> y = 6
1 l - (1) + y =6 => y = 6 +1 => y = 7
2 l - (2) + y =6 => y = 6 + 2=> y = 8

Solve -2(2x + 5) - 3 = -3(x - 1).
The solution for the equation -2(2x + 5) - 3 = -3(x - 1) is x = - 16 which can be solved by the use the distributive property.
What is distributive property?Distributive Property that when we multiply a number by a group of numbers that are added together, we can multiply each value in the group separately, then add the products of the multiplications.
-2(2x + 5) - 3 = -3(x - 1)
To solve this equation, we need to first use the distributive property to expand the left side of the equation.
We have:
-4x-10-3 = -3(x - 1)
-4x-13 = -3(x - 1)
Now, we can group the like terms on the left side and the right side of the equation.
On the left side, we have -4x - 13 and on the right side, we have -3x + 3.
-4x-13 = -3x + 3
To solve for x, we can add 3x to left side of the equation and add 13 to the right side.
This results in the equation:
-4x+ 3x = 13 + 3
Now, we can add 3x with -4x of the equation to isolate the x-term.
We have:
-x = 16
x = - 16

First add [tex]\frac{1}{4} and\frac{3}{8}[/tex] canvert 1/4 by multiplying by 2/2 to get a commmon denominator.
[tex]\frac{1}{4} *\frac{2}{2} =\frac{2}{8}[/tex]

Now find a common denominator for 3/5 and 5/8 by multiplying 3/5 by 8/8 and 5/8 by 5/5.
[tex]\frac{3}{5}*\frac{8}{8}=\frac{24}{40}[/tex]

Answer:
Quantitative Discrete
Step-by-step explanation:
The data about the average salary of all general motor workers cooled ONLY as WHOLE U. S DOLLARS
Firstly, data involving worker's salary are best expressed in figure, hence making such data numerical in nature. Numerical variables are quantitative data as it allows for numerical computation and analysis such as addition, subtraction, mean of the data values and so on.
Secondly, since these data has been strictly restricted to be expressed in whole numbers, this makes the range of the data collected finite and hence countable. This properties ensure that the quantitative data (average salary) is discrete in nature.
