Two important ingredients for baking bread are yeast and flour. To make a loaf of
bread of at most 40 servings, maintain a yeast to flour ratio of 1:200. If you're making
a loaf of more than 40 servings, use a ratio of 1:180.
If you're making 40 servings of bread and using 0.35 oz of yeast, how many ounces of
flour do you need?
If you're making 90 servings of bread and using 360 oz of flour, how many ounces of
yeast do you need?
Answers
Using proportions, it is found that:
70 ounces of flour are needed for 40 servings of bread and using 0.35 oz of yeast.180 ounces of yeast are needed for the 90 servings of bread using 360 oz of flour.What is a proportion?A proportion is a fraction of total amount, and the measures are related using a rule of three.
For 40 servings:
1 oz of yeast is equivalent to 200 oz of flour. How many oz of flour are needed for 0.35 oz of yeast?The rule of three is:
1 oz yeast - 200 oz flour
0.35 oz yeast - x oz flour.
Applying cross multiplication:
[tex]x = 200(0.35) = 70[/tex]
70 ounces of flour are needed for 40 servings of bread and using 0.35 oz of yeast.
For 90 servings:
1 oz of yeast is equivalent to 180 oz of flour. How many oz of yeast are needed for 360 oz of flour?The rule of three is:
1 oz yeast - 180 oz flour
x oz yeast - 360 oz flour.
Applying cross multiplication:
[tex]2x = 360[/tex]
[tex]x = \frac{360}{2}[/tex]
[tex]x = 180[/tex]
180 ounces of yeast are needed for the 90 servings of bread using 360 oz of flour.

=============================================================
Explanation:
If that point is the center, then we have two pizza slices that sweep out 60 degrees of a central angle.
The full circle has pi*r^2 = pi*5^2 = 25pi square units of area
We only want 60/360 = 1/6 of that for each slice, so 2*(1/6) = 1/3 of the full circle area is shown by the shaded region
(1/3)*(full circle area) = (1/3)*25pi = 25pi/3 square units is the shaded area

Louise buys 1 pack of pencils and 1 box of crayons for her son for $3.39. Elaine buys 7 packs of pencils and 8 boxes of crayons for her students for $25.88.
Answers
Answer:
Step-by-step explanation:
p+c=3.39, p=3.39-c
7p+8c=25.88, using p=3.39-c in this equation gives you
7(3.39-c)+8c=25.88
23.73-7c+8c=25.88
23.73+c=25.88
c=2.15, since p=3.39-c
p=3.39-2.15
p=1.24
So pencils cost $1.24 and crayons cost $2.15

Find the Width of the Rectangular Prism.
Answers
Answer:
w = V/12 IN X= 840in then 840÷12 = 70in
A rectangular prism has 70in width having volume 840in³, length is 2in, and height 6in.
What is a rectangular prism?A rectangular prism or a cuboid is a three-dimensional closed figure which has volume along with surface area.
The volume of a cuboid is the product of its length, width, and height.
V = (l×w×h).
The total surface area of a cuboid is 2( lw + wh + wl) and the lateral surface area is 2(l + w)×h.
Given, A rectangular prism has a volume 840 in³, its length is 2 in and its height is 6in.
Assuming width to be w in.
∴ (l×w×h) = volume.
(2×w×6) = 840.
12w = 840.
w = 70 in.

Identifying Proportional Relationships
Which graph represents a proportional relationship?
Answers
Answer:
There aren't any graphs that you attached so i can't see which one is a proportional graph, but the one that is going up by a constant proportional rate of change would be the proportional graph.
Proportional relationship graphs always start at the point 0 for x and y. The line always crosses through to origin. 0
Step-by-step explanation:
Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".

4. The two legs of a right triangle are equal and the square of its hypotenuse is 50. Find the
length of each leg.
Answers
Answer:
[tex]Opposite = Adjacent= 5[/tex]
Step-by-step explanation:
Given
[tex]Hypotenuse^2 = 50[/tex]
[tex]Opposite = Adjacent[/tex]
Required
Find the length of each leg
This is calculated using Pythagoras Theorem
[tex]Opposite^2 + Adjacent^2 = Hypotenuse^2[/tex]
[tex]Opposite^2 + Adjacent^2 = 50[/tex]
Represent the opposite and adjacent with x
[tex]x^2 + x^2= 50[/tex]
[tex]2x^2 = 50[/tex]
Divide both sides by 2
[tex]x^2 = 25[/tex]
Take square roots
[tex]x = 5[/tex]
Hence:
[tex]Opposite = Adjacent= 5[/tex]

[tex]x=\frac{-4}{33}[/tex]
Step-by-step explanation:
Let's start with simplifying the equation. To do this, let's simplify the parenthesis. We can use the distributive property to simplify the parenthesis. We now have
[tex]2x-6x+9+3=45[/tex]
Next, we can start adding. We can add 2x and 6x, and 9 and 3.
[tex]-4x+12=45[/tex]
Now that we've simplified the equation, we can start solving the equation. First, let's subtract 12 from each side.
[tex]-4x=33[/tex]
The last thing that we need to do is divide -4 from each side.
[tex]x=\frac{-4}{33}[/tex]
