Answer:
1
Step-by-step explanation:
I am assuming the question is asking which x value plugged into the function will give you a zero so
(-1)3 -8(-1)2 -23(-1)+30
so that simplyfiys to -1-8(1)+23+30
so that is -1-8+53
so -9+53
= 44
trying 3 we get
(3)3-8(3)2-23(3)+30
so that is 27 -72-69+30
and that is not zero
trying -10
we get
(-10)3-8(-10)2-23(-10)+30
which is -1000- 800+230+30
that is not zero so lastly trying 1 we get
(1)3-8(1)2-23(1)+30
which is 1-8-23+30
which is -7+7 which is zero

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.

Answers
Answer:
(d) and (e) are true
Step-by-step explanation:
Given
[tex]Food = 23\ oz[/tex]
See attachment for proper presentation of question
Required
Select all true statements
For any option to be true, it must satisfy the following condition.
[tex]Days * Food = 23[/tex]
Option (a):
[tex]Days = 6[/tex]
[tex]Food = 4\frac{1}{6}[/tex] per day
So, we have:
[tex]Days * Food = 6 * 4\frac{1}{6}[/tex]
[tex]Days * Food = 6 * \frac{25}{6}[/tex]
[tex]Days * Food = 25[/tex]
This is not true because: [tex]25 \ne 23[/tex]
Option (b):
[tex]Days = 10[/tex]
[tex]Food = 2\frac{2}{23}[/tex] per day
So, we have:
[tex]Days * Food = 10 * 2\frac{2}{23}[/tex]
[tex]Days * Food = 10 * \frac{48}{23}[/tex]
[tex]Days * Food = \frac{480}{23}[/tex]
[tex]Days * Food = 21[/tex] --- approximated
This is not true because: [tex]21 \ne 23[/tex]
Option (c):
[tex]Days = 8[/tex]
[tex]Food = 3\frac{1}{8}[/tex] per day
So, we have:
[tex]Days * Food = 8 * 3\frac{1}{8}[/tex]
[tex]Days * Food = 8 * \frac{25}{8}[/tex]
[tex]Days * Food = 25[/tex] --- approximated
This is not true because: [tex]25 \ne 23[/tex]
Option (d):
[tex]Days = 11[/tex]
[tex]Food = 2\frac{1}{11}[/tex] per day
So, we have:
[tex]Days * Food = 11 * 2\frac{1}{11}[/tex]
[tex]Days * Food = 11 * \frac{23}{11}[/tex]
[tex]Days * Food = 23[/tex] --- approximated
This is true because: [tex]23 = 23[/tex]
Option (e):
[tex]Days = 7[/tex]
[tex]Food = 3\frac{2}{7}[/tex] per day
So, we have:
[tex]Days * Food = 7 * 3\frac{2}{7}[/tex]
[tex]Days * Food = 7 * \frac{23}{7}[/tex]
[tex]Days * Food = 23[/tex] --- approximated
This is true because: [tex]23 = 23[/tex]

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".

Mark is buying supplies for his students. He is buying a notebook (n) and a pack of pencils for each of his 25 students. Each pack of pencils costs $1.25.
If Mark's total cost is $156.25, which of the following equations can be used to find how much each notebook cost? Select TWO that apply.
A - 25(n) +31.25 =165.25
B - 1.25(n)+25=156.25
C- 25(n)=156.25+31.25
D - 25(n)=156.25−31.25
Answers
$5
Step-by-step explanation:
Note. There are no options to select.
Let the notebook cost x, then Mark spent:
25x + 25*1.25 = 156.25
25x + 31.25 = 156.25
25x = 156.25 - 31.25
25x = 125
x= 125/25
x= 5

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.
