Answer:
2
Step-by-step explanation:
if she has 3 dogs and each gets a pound of food. Each can if food has .75 pounds in it then you would times that by then you would get 4 cans of food.
Shawna wants to leave 1 pound of food per dog, and she has 3 dogs. So, she needs 3 pounds of food in total.
What is the division operation?In mathematics, divides left-hand operands into right-hand operands in the division operation. The primary purpose of the division is to generate equal groupings or to determine how many people are in each category after a fair distribution.
For example 4/2 = 2
A can of dog food has 0.75 pounds of food.
To determine the number of cans of food Shawna should leave, divide the total amount of food she needs (3 pounds) by the amount of food in each can (0.75 pounds).
⇒ 3 pounds / 0.75 pounds/can = 4 cans of food.
Therefore, Shawna should leave 4 cans of food for her 3 dogs.

Answer:

Step-by-step explanation:
One cell phone company offers a plan that costs $22.99 and includes unlimited night and weekend minutes. Another company offers a plan that costs $11.99 and charges $0.35 per minute during nights and weekends. For what numbers of night and weekend minutes does the second company's plan cost more than the first company's plan?
Answer:
From 0 to 31.43 minutes Plan 2 is cheaper. From 31.44 Plan 1 is better.
Step-by-step explanation:
First, we need to structure the total cost formula for each fitness center:
Plan 1= 22.99
Plan 2= 11.99 + 0.35x
x= number of minutes
Now, we equal the formulas and isolate x:
22.99= 11.99 + 0.35x
11=0.35x
31.43=x
The indifference point is 31.43 minutes.
From 0 to 31.43 minutes Plan 2 is cheaper. From 31.44 Plan 1 is better.
How can you get the variable alone on one side of the equation c4=139?
A. Multiply both sides of the equation by 4.
B. Add 139 to both sides of the equation.
C. Subtract 139 from both sides of the equation.
D. Divide both sides of the equation by 4.
Answer:
a
Step-by-step explanation:
since c/4 = 139 is the equation, c/4 is a fraction. To get rid of the denominator you have to multiply the denominator in both sides.
If it was x/2 = 4. then multiply 2 on both sides to get 8.

Julio walks 2.8 miles in one hour.
Step-by-step explanation:
Answer:
2.8miles/hr
Step-by-step explanation:
Given parameters:
Distance walked = 3.5miles
Time taken = 1.25hrs
Unknown:
Number of miles walked per mile = ?
Solution:
The miles walked per hour is defined as the speed.
Speed is the distance divided by time;
Speed = [tex]\frac{Distance}{time taken}[/tex]
Insert parameters and solve;
Speed = [tex]\frac{3.5}{1.25}[/tex] = 2.8miles/hr
Which expression is equivalent to the given polynomial expression?
13p – 3p(1 – 2m) – m(2m – 5p) – m2
Answer:-3m^2+11mp+10p
Step-by-step explanation:
The equivalent expression is:
-3m² + 11mp + 10p
Hence the correct option is 2.
Given is polynomial expression 13p – 3p(1 – 2m) – m(2m – 5p) – m², we need to find an equivalent expression to it,
To simplify the given polynomial expression, let's expand and combine like terms:
13p - 3p(1 - 2m) - m(2m - 5p) - m²
Expanding the expressions inside parentheses:
13p - 3p + 6mp - 2m² + 5mp - m²
Combining like terms:
10p + 11mp - 3m²
Rearranging the terms:
-3m² + 11mp + 10p
Therefore, the equivalent expression is:
-3m² + 11mp + 10p
Hence the correct option is 2.

We have a lot of square roots, and we want to find, for each one, two consecutive integers such that one is smaller than the square root and the other is larger.
The solutions are:
1) 10 and 112) 7 and 83) 4 and 54) 15 and 165) 8 and 96) 5 and 67) 14 and 158) 6 and 79) 10 and 1110) 3 and 4----------------------------
To find the integers, we just need to find two integers such that one squared is smaller than the argument of the square root and the other squared is larger than the argument of the square root.
1) √120
Here we can use:
10*10 = 100
11*11 = 121
Then:
10 < √120 < 11
2) √56
Here we can use:
7*7 = 49
8*8 = 64
then:
7 < √56 < 8
3) √19
Here we can use:
4*4 = 16
5*5 = 25
then:
4 < √19 < 5
4) √240
Here we can use:
15*15 = 225
16*16 = 256
then:
15 < √240 < 16
5) √80
Here we can use:
8*8 = 64
9*9 = 81
then:
8 < √80 < 9
6) √27
Here we can use:
5*5 = 25
6*6 = 36
then:
5 < √27 < 6
7) √199
Here we can use:
14*14 = 196
15*15 = 225
then:
14 < √199 < 15
8) √38
Here we can use:
6*6 = 36
7*7 = 49
then:
6 < √38 < 7
9) √102
Here we can use:
10*10 = 100
11*11 = 121
then:
10 < √102 < 11
10) √11
Here we can use:
3*3 = 9
4*4 = 16

3 < √11 < 4.

The National park service is building a 16-mile trail. They will post a sign every 1/8 mile along the trail, including one at the end. There will not be a sign posted at the beginning of the trail. How many signs will they post along the trail? Please can you show me how you got your answer please.
Answer:
128 signs will be posted along the trail
Step-by-step explanation:
From the question,
The national park service is building a 16-mile trail and they will post a sign every 1/8 mile along the trail. To determine how many signs will be posted along the trail, we will divide the length of the trail by the distance in which one sign is to be posted from another.
The length of the trail = 16 mile
The distance in which one sign is to be posted from another = 1/8 mile
Hence,
Number of signs that will be posted along the trail = 16 mile ÷ 1/8 mile
= 16 × 8/1 = 128
Number of signs that will be posted along the trail = 128
This includes the sign that will be posted at the end of the trail.
Since there will not be a sign posted at the beginning of the trail, then
128 signs will be posted along the trail.
What is the slope of the line passing through the points
(5, 3) and (9, -6)?
Answer:
-9/4
Step-by-step explanation:
So the formula is [tex]y^2-y^1= rise\\x^2-x^1= run[/tex]
All you have to do is the second y-coordinate of the points minus the first y-coordinate. That should be -6 - 3= -9
Then for the run, you do 9 - 5= 4
Therefore, it is -9/4

Answer:
[tex]h(f(x)) =6x-2[/tex]
Step-by-step explanation:
Given
[tex]f(x) = (3x-5)^3\\h(x) = 2\sqrt[3]{x}+8[/tex]
Required
Write [tex]h(f(x))[/tex] in terms of x
[tex]h(f(x)) = h((3x-5)^3)[/tex]
To get [tex]h((3x-5)^3)[/tex], we will replace x in h(x) with (3x-5)³ as shown:
[tex]h((3x-5)^3) = 2\sqrt[3]{(3x-5)^3} +8\\ h((3x-5)^3) = 2(3x-5) + 8\\ h((3x-5)^3) = 6x - 10 + 8\\ h((3x-5)^3) = 6x-2\\Hence \ h(f(x)) =6x-2[/tex]
Hence the expression [tex]h(f(x))[/tex] in terms of x is 6x - 2
