Answer: The sprayer can hold 150 ounces, and Pam needs to add 120 ounces of water.
Step-by-step explanation:
The data that we know is:
We must use 30 oz of cleaning concentrate.
The end product must be 80% water and 20% cleaning concentrate.
This means that:
Mass of water/total mass in the sprayer = 0.8
mass of cleaning concentrate/total mass in the sprayer = 0.2
Then, let's define the variables:
X = ounces that the sprayer can hold.
Y = ounces of water added.
Then we have the equations:
30oz + X = Y.
30oz/Y = 0.20
X/Y = 0.80
From the second equation we can find the value of Y.
30oz = 0.20*Y
30oz/0.20 = Y = 150oz.
Then the sprayer can hold 150 ounces.
Now from the third equation we have:
X/Y = 0.8
We know that Y = 150oz
Then:
X/150oz = 0.8
X = 0.8*150oz = 120 oz.
Then the water that must be added is 120 ounces.
Biologist Dr. Cytoplasm wants to know how many elephants in the nature reserve have broken tusks . Of the 30 elephants that he observes in random places in the reserve, he counts 8 elephants with broken tusks. Of the 600 elephants in the reserve, how many can he expect to have broken tusks?
Answer:
Of the 600 elephants that he observes in random places in the reserve, he counts [tex]\frac{8}{30}(600)=160[/tex] elephants with broken tusks.
Step-by-step explanation:
Let x denotes number of elephants having broken tusks out of 600 elephants.
Of the 30 elephants that he observes in random places in the reserve, he counts 8 elephants with broken tusks.
So,
Of the 1 elephants that he observes in random places in the reserve, he counts [tex]\frac{8}{30}[/tex] elephants with broken tusks.
Therefore,
Of the 600 elephants that he observes in random places in the reserve, he counts [tex]\frac{8}{30}(600)=160[/tex] elephants with broken tusks.
What's the circumference of a circle with a diameter of 9 inches?
Answer:
9pi
Step-by-step explanation:

radius = diameter \ 2
r = 9 \ 2 = 4.5in.
c = 2 (pi) (4.5)
c = 9pi or 28.3in.

NUMBER 4!!!!!!! if m∠JKP= 67°, find m∠NKO
Answer:
Step-by-step explanation:
I have some sympathy for the way the questions have been set up and numbered.
The givens are that the two lines that look like they are perpendicular, are perpendicular.
<JKP = 67 Given
<PKL = 180 - 67 < PKL is supplementary to <JKP
<PKL = 113
<PKM = 113 - 90 = 23
Here's what you want to know. <NKO = PKM because they are vertically opposite angles.
Therefore NKO = 23 degrees.
JL is perpendicular to MN, then
m ∠NKO= 23°
Given :
JL is perpendicular to MN and the m∠JKP= 67°
we need to find out m∠NKO
we know that JL is perpendicular to MN. so, <JKN makes an right angle .
m ∠JKN = 90°
PO is a straight line . It makes an angle 180 degree
m ∠JKP +m ∠JKN +m ∠NKO =180
[tex]67+90+m<NKO=180\\m<NKO=180-90-67\\m<NKO=23[/tex]
m ∠NKO= 23°

A hiker is 3.5 miles from her campsite when she begins to walk back to it. She hikes back toward the campsite at a constant rate of 2.1 miles per hour.
Which equation models the distance of the hiker from her campsite? (Let m represent her distance, in miles from the campsite and h represent the number of hours since she begin walking back.)
O m= 3.5+ 2.1h
Om= 3.5h - 2.1
O m = 3.5h + 2.1
m = 3.5 - 2.1h

The product of two radicals is always an irrational number.
AIways True
Never True
Sometimes True
Answer:
The answer is Sometimes True.
Step-by-step explanation:
Radicals are number that have roots (√) .
Irrational are numbers that cannot be written in a form of fraction (a/b) .
I will show you some examples :
√2 × √2 = 2 (rational)
√2 × √5 = √10 (irrational)
Therefore, the products of 2 radicals will sometimes give rational or irrational numbers.

The total number of calories consumed by Ethan when eating French fries varies directly with the number of French fries that Ethan eats. Ethan eats 16 French fries and consumes 224 calories. How many French fries does Ethan eat if he consumes 406 calories?
Answer:
29 French fries
Step-by-step explanation:
Total number of calories consumed by Ethan when eating French fries varies directly as the number of French fries that Ethan eats
The first step is to calculate the constant k
No of calories= k × no of French fries
k = No of calories/No of French fries
k = 224/16
k = 14
Therefore the number of French fries eaten by Ethan if he consumes 406 calories can be calculated as follows
No of French fries= No of calories/k
= 406/14
= 29
Hence Ethan eats 29 French fries if he consumes 406 calories

Which is correct equation , in slope intercept form , for the line described below?
x-intercept =-2
Y-intercept=6
Answer:
[tex]y=3x+6[/tex]
Step-by-step explanation:
Equation of the line
The equation of the line in slope-intercept form is:
[tex]y=mx+b[/tex]
Being m the slope and b the y-intercept.
We are given two points for the required line: The x-intercept is -2, thus the point is (-2,0), and the y-intercept b=6 represents the point (0,6).
Since the value of b is 6, we use the first point to find the slope:
[tex]0=m(-2)+6[/tex]
Solving:
m=3
The correct equation of the line is:
[tex]\boxed{y=3x+6}[/tex]
