Brooke goes to the lumber yard with her grandfather. They buy boards for a garden fence. what is the sum of the lenghts of the boards that are less than 4 feet long?
The sum of the lengths that are less than the feet given in their case will be 6.69 feet.
How to calculate the sumYour information is incomplete as the values aren't given. Therefore, assumed lengths will be given in this scenario.
Let's assume that the lengths of the boards that are less than 4 feet long include 3.4 feet, 1.2 feet, and 2.09 feet.
In this case, you'll add the sum together. This will be:

-18
Step-by-step explanation:
F(x)=3x-12
F(-2)=3x-2-12
=-6-12
=-18
How do you find Domain and Range?
Answer:
The domain is the set of values you put into the function.
The range is the set of values the function outputs.
Example problem:
Find the range of this function: y = 2x + 3, x > 0
The x > 0 part is the domain, so this means that only positive values of x can be inputted in the function.
If only positive values can be inputted in the function, then the range will be: y > 3

3. 1/6
4. 1/4
5. 7/4
6. 3/2
7. 5/1
8. 2/7
9. 1/4
Step-by-step explanation:
A ratio compares values.
So if there are 3 oranges and 12 apples, we can say that there is a ratio of 3 : 12 meaning there are 3 oranges for every 12 apples.
Ratios can be written in different ways, but they mean the same thing:
Using the ":" to separate the values: 3 : 12Or using the word "to" to separate the values: 3 to 12or as a fraction: [tex]\frac{3}{12}[/tex]A ratio can also be scaled up or scaled down (as long as we do the same thing to both values):
3 : 12 is the same as 6 : 24 (multiplied both values by 2)3 : 12 is the same as 1 : 4 (divided both values by 3)1. 2 to 4 = 2 : 4 = 2/4
We can reduce this fraction by dividing both the numerator (top value) and denominator (bottom value) by 2: 2/4 = 1/2
2. 15/20
Reduce this fraction by dividing both the numerator (top value) and denominator (bottom value) by 5:
15/20 = 3/4
3. 6 : 18 = 6/18
Reduce this fraction by dividing both the numerator (top value) and denominator (bottom value) by 6:
6/18 = 1/6
4. 3 to 12 = 3 : 12 = 3/12
Reduce this fraction by dividing both the numerator (top value) and denominator (bottom value) by 3:
3/12 = 1/4
5. 7 : 4 = 7/4
This fraction cannot be reduced any further as the numerator is a prime number. Prime numbers are whole number greater than 1 that cannot be made by multiplying other whole numbers.
6. 18/12
Reduce this fraction by dividing both the numerator (top value) and denominator (bottom value) by 6:
18/12 = 3/2
7. 35 : 7 = 35/7
Reduce this fraction by dividing both the numerator (top value) and denominator (bottom value) by 7:
35/7 = 5/1
(5/1 = 5 however the question is asking you to write the ratio in the lowest fraction, so the lowest fraction is 5/1)
8. 8/28
Reduce this fraction by dividing both the numerator (top value) and denominator (bottom value) by 4:
8/28 = 2/7
9. 24 : 96 = 24/96
Reduce this fraction by dividing both the numerator (top value) and denominator (bottom value) by 24:
24/96 = 1/4

a 4-pound bag of potatoes costs $3.16 how much would 32 pounds of potatoes costs
Answer:
$25.28
Step-by-step explanation:
Since a 4 pound bag cost $3.16 you would do 32 divided by 4 and you would get 8. Then you would do 8 times 3.16 and you get 25.28.
The long way:
4 bags = 3.16
8 bags = 6.32
12 bags = 9.48
16 bags = 12.64
20 bags = 15.80
24 bags = 18.96
28 bags = 22.12
32 bags = 25.28

A science teacher has 30 pounds of salt and 20 liters of water to use for a class experiment. Each of the 8 groups of students will receive an equal share of both the salt and the water. How much of the salt and water will each group get?
Answer:
3 3/4 lb salt2 1/3 L waterStep-by-step explanation:
Each group will get 1/8 of the total amount:
salt: (30 lb)/8 = 3 6/8 lb = 3 3/4 lb
water: (20 L)/8 = 2 4/8 L = 2 1/2 L
Each group will get 3 3/4 pounds of salt and 2 1/2 liters of water.

A scientist needs to make 5.4 liters of saline solution (salt water), in which the salt level must be at 28% concentration (meaning 28% of the water is salt). Unfortunately, the scientist only has two types of saline solution in his possession. He has saline solution with a 12% concentration level and saline solution with a 30% concentration level.
How much of each type of saline solution should the scientist mix together to achieve 5.4 liters of saline solution at a concentration level of 28%?
By solving a system of equations, we will see that the scientist needs to use:
1.444 liters of the 12% solution.3.956 liters of the 30% solution.How to find the system of equations?
First, we need to define the variables, we will use:
x = liters of the 12% solution used.y = liters of the 30% solution used.We know that the scientist needs 5.4 liters, then we will have that:
x + y = 5.4
We also know that the end concentration for these 5.4 liters must be 28%, then the concentration in the left side must be the same as the one in the right side, this gives the equation:
0.12*x + 0.30*y = 0.28*(5.4)
0.12*x + 0.30*y = 1.512
Then the system of equations is:
x + y = 5.4
0.12*x + 0.30*y = 1.512
To solve it, we first need to isolate one of the variables in one of the equations, I will isolate x in the first one.
x = 5.4 - y
Now we can replace this in the other equation to get:
0.12*(5.4 - y) + 0.30*y = 1.512
0.81 - 0.12*y + 0.30*y = 1.512
(0.30 - 0.12)*y = 1.512 - 0.81
0.18*y = 0.712
y = (0.712)/0.18 = 3.956
And to find the value of x, we use:
x = 5.4 - y = 5.4 - 3.956 = 1.444
So the scientist needs to use:
1.444 liters of the 12% solution.3.956 liters of the 30% solution.If you want to learn more about systems of equations, you can read:

There are 39 people on a city bus. The ratio of adults to children is 10 : 3. At the next stop, 3 adults get off the bus. What is the new ratio of adults to children on the bus?
A 3 : 1
B 9 : 2
C 7 : 3
D 12 : 1
Answer:
3:1
Step-by-step explanation:
Looking at the numbers
39 and a ratio of 10:3 kinda scream that there are 30 adults and 9 children to me, but when 3 adults get off, that is only 36 people.
this means,
27 adults,
and
9 children
so if it doesn't look obvious enough, 9 x 3 is 27, so that means that 3: 1 must be our ratio because the 3 in 3:1 multiplied by 9 is 27 which is the number of adults, and the 1 in children multiplied by 9 is 9!
so there you have it, 27/9 = 3
and
9/9=1
so
3: 1
