A store manager combines trail mix that is 30% raisins with a trail mix that is 55% raisins. He makes 800lb of trail mix that is 40% raisins. How many pounds of each trail mix does the manager use?
Answer:
320 pounds of 55% raisins trail mix
480 pounds of 30% raisins trail mix
Step-by-step explanation:
Sorry, I can’t write how I got the answer. We just did it in class and decided to help... (Btw, sorry if I’m too late)
The store manager mixed 320 pounds of 55% raisins trail mix and 480 pounds of 30% raisins trail mix.
Given that,
A store manager combines a trail mix that is 30% raisins with a trail mix that is 55% raisins.
He makes 800lb of trail mix that is 40% raisins.
We have to determine,
How many pounds of each trail mix does the manager use?
According to the question,
Let, x = pounds of trail mix 30% raisins
y = pounds of trail mix 55% raisins
The distributor wants to make 800 pounds of trail mix, thus:
x + y = 800
The mix must be 40% raisings as a combination of x and y, thus:
30x + 55y = 40 × 800
30x + 55y = 32,000
Divided by 5 the equation
6x + 11y = 6400
Solving both the equation
[tex]x + y = 800\\\\x = 800 -y\\[/tex]
Substitute the value of x in equation 2,
[tex]6x + 11y = 6400\\\\6 (800-y) + 11y = 6400\\\\4800 - 6y +11y = 6400\\\\5y = 6400-4800\\\\5y = 1600\\\\y = \dfarc{1600}{5}\\\\y = 320[/tex]
Substitute the value of x in equation 1
[tex]x + y = 800\\\\x + - 800 -y\\\\x = 800-320\\\\x = 480[/tex]
Hence, The store manager mixed 320 pounds of 55% raisins trail mix and 480 pounds of 30% raisins trail mix.

Answer:
a = 7
Step-by-step explanation:
Write the equation with all the components.
97 (cost) = 8a +41
Isolate the variable.
97 = 8a + 41
-41 -41
56 = 8a
Divide both sides by 8.
You're left with 7=a and that's your answer. Hope this helps :)

Answer:
1. 672 inches
Step-by-step explanation:
Question #1
The formula for the volume of a triangular prism is:
V = [tex]\frac{bh}{2}[/tex]
Where V is the volume, b is the area of the base, and h is the height. You are given the volume and the height. Plug those numbers into your equation.
[tex]4704 = \frac{b(14)}{2}[/tex]
Now, solve for b. To do this, you must isolate the variable b.
The first step to do this is to multiply both sides by 2. This will get you:
4704(2) = 14b
9408 = 14b
Now, divide both sides by 14 to get:
672 = b.
Therefore, the area of the base is 672 inches.
Question #2
To solve this problem, separate the figure into 2 shapes. You have a triangle with a base of 6 cm and a height of 6 cm, as well as a semicircle with a radius of 3 cm.
After you do this, find the area of each shape separately.
The formula for the area of a triangle is:
[tex]A = \frac{bh}{2}[/tex],
where A is the area, b is the length of the base, and h is the height. You know the base and the height, so plug those into your equation. You will get:
[tex]A = \frac{6*6}{2}\\\\A = \frac{36}{2}\\\\A = 18[/tex]
Now you know that the area of the triangle is 18 cm^2.
Let's find the area of the semicircle.
The formula for the area of a semicircle is:
A = [tex]\frac{1}{2}[/tex]π[tex]r^2[/tex]
You know the radius, so plug that in to get:
A = [tex]\frac{1}{2}[/tex]π([tex]3^2[/tex])
A = [tex]\frac{1}{2}[/tex]π(9)
Simplify this to get:
A = 4.5π.
Now, either multiply 4.5 by π to get:
14.1371669412 cm^2
or, multiply 4.5 by 3.14 to get:
14.13 cm^2.
Then, add the area of the triangle, 18 cm^2, by the area of the triangle, 14.13, to get:
32.13 cm^2.

Choose the symbol to make the following statement true. 4 yd. ___12 ft. A. C . =
Answer:
C. =
Step-by-step explanation:
Note the conversion for Yard to Feet.
1 yard = 3 feet.
In this case, it is given to you that there are 4 yards. Multiply 4 with 3 to get the amount of feet:
4 yd x 3 ft per yd = 12 feet per 4 yd.
12 ft. = 12 ft., ∴ 4 yd. = 12 ft.
