Equation to determine how many pairs of shoes :- S = 40 + 4.5x
Where,
S is Earnings
x is Shoe
⇒ 112 = 40 + 4.5x
⇒ 40 + 4.5x = 112
⇒ 4.5x = 112 - 40
⇒ 4.5x = 72
⇒ 4.5x/4.5 = 72/4.5
⇒ x = 16
[tex]\therefore [/tex] Roger must sell 16 shoes per day to meet his daily earning goal
Can someone help me with this math equation? Can you explain how to work it out also?

There were 500 animals at an animal shelter. On Saturday, 20 of the dogs and 15 of the cats were adopted. What percentage of the animals were adopted that day?
10%
5%
35%
7%
Answer:
7%
Step-by-step explanation:
First, let's add the 20 dogs and 15 cats together to find the total number of animals adopted
20 + 15 = 35 animals adopted
We cand do 35 ÷ 200 to find how much of a percent 35 is of 500
35 / 500 = 0.07
Multiply this number by 100 to get a percent
0.07 × 100% = 7%
7% of the animals

(I already know the answer is 3300)
Answer:
[tex]3300ft^{3}[/tex]
Step-by-step explanation:
For this problem it is easier to split it up into two shapes. One being the big box(1) on top and the other being the small box(2) below it.
Volume of box 1:
[tex]Volume = length*width*height[/tex]
[tex]Volume of Box 1 = 25ft*(20+4)ft*5ft = 3000ft^{3}[/tex]
Volume of box 2:
[tex]Volume = length*width*height[/tex]
[tex]Volume of Box 2 = 25ft*4ft*(8-5)ft=300ft^{3}[/tex]
Total volume:
[tex]Total Volume = Volume of Box 1 + Volume of Box 2 = 3000ft^{3}+300ft^{3} = 3300ft^{3}[/tex]
The volume of the figure, by splitting it into two cuboids comes to be 3300 ft³.
Let us split the given figure into two cuboids
The dimensions of one cuboid = 20 ft*25 ft *5ft
The dimension of the other cuboid = 4 ft*25ft * 8ft
So, the volume of the figure will be the sum of the volume of both the cuboids.
What is the volume of a cuboid?The volume of a cuboid is the product of its three dimensions i.e. length, breadth, and height.
So, the volume of the cuboid with dimensions 20 ft*25 ft *5ft
= 20*25*5
=2500 ft³.
The volume of the cuboid with dimensions 4 ft*25ft * 8ft
=4*25*8
=800 ft³.
So, the volume of the figure = 2500 + 800 =3300 ft³.
Therefore, the volume of the figure, by splitting it into two cuboids comes to be 3300 ft³.

Jenny is studying the growth of a particular type of plant. She is testing the effects of three growth factors: lighting, age, and temperature. Here are the levels she's testing for each.
Growth factor Levels
Lighting Low, Medium, High, Very high
Age month, months, months, months, months
Temperature , , ,
She wants to find the number of ways of combining one level from each of the growth factors. How many ways are there?
Answer:
80
Step-by-step explanation:
For these types of counting problems, just multiply all of the levels.
For example, this would be
4 choices
5 choices
4 choices
Multiply 4*5*4, and you get 80.
Total number of ways of combining one level from each of the growth factors is equals to 80.
What is fundamental principle of counting?" As per fundamental principle of counting if first event has 'm' number of possible outcomes , second has 'n' number of possible outcomes then total number of ways are m× n ."
According to the question,
Number of growth factors =3
First growth factor: Lightening
Second growth factor: Age
Third growth factor : Temperature
As per the data given we have,
Number of levels in lightening 'm'= 4
Number of levels in age 'n'= 5
Number of levels in temperature 'p' =4
Substitute the value as per the definition of fundamental principle of counting
Total number of ways = m × n × p
= 4 × 5 × 4
= 80 ways
Hence, total number of ways of combining one level from each of the growth factors is equals to 80ways.

please help me!!!
Answer:
42 and 41
Step-by-step explanation:
So how I did it tbh I went everywere with this but I went backwards because the how you find the mean of something is adding all the values and then dividing them by the number of values(40+41+42+45+45+48+54=315, 315divided by 7=45) but anyway 45x7(because multiplication is the opposite of division)that equals 315-232 which is the answer to 40+45+48+54+45 which were the numbers that were given

Answer: 909.03
Step-by-step explanation:
We know that the equation is an exponential function, it can be written as y=ab^x
[tex]100 &=a b^{6.5} \dots \mathrm{Equation \ 1} \\11 &= a b^{1} \\[/tex]
[tex]\Rightarrow ab^1=11[/tex]
[tex]\Rightarrow \frac{ab^1}{b}=\frac{11}{b};\quad \:b\ne \:0[/tex]
[tex]\Rightarrow a=\frac{11}{b}[/tex]
a = 11/b, substitute it in equation 1
[tex]100 &=a b^{6.5}[/tex]
[tex]\Rightarrow 100=\left(\frac{11}{b}\right)b^{6.5}[/tex]
[tex]\Rightarrow 100b=11b^\frac{11}{2}[/tex]
[tex]\Rightarrow 11\sqrt{b^{11} } =100b[/tex]
[tex]\Rightarrow \sqrt{b^{11} } =\frac{100}{11}}[/tex]
[tex]\Rightarrow \sqrt{b^{11} } =\frac{100}{11}}[/tex]
[tex]\Rightarrow {b^{11} } =\frac{10000}{121}}[/tex]
[tex]\Rightarrow {b} =\frac{\sqrt[11]{10000 \cdot 11^9} }{11}[/tex]
[tex]\Rightarrow {b} = 1.49379[/tex]
a = 11/b
a = 11/(1.49379)
a = 7.36382
Equation: y = (7.36382)(1.49379)^x
Now plug in 12 for x:
[tex]\Rightarrow { \left(7.36382\right)\left(1.49379\right)^{12}[/tex]
[tex]\Rightarrow 7.36382\cdot \:1.49379^{12}[/tex]
[tex]\Rightarrow 7.36382\cdot \:123.44530\dots[/tex]
[tex]\Rightarrow 909.03[/tex]

Zoe considers the lunch choices as she looks at the menu. What is the probability that she will choose cheese pizza, apple, milk?
Meal: Cheese Pizza, Cheeseburger, Hotdog, Salad
Side: Banana, Apple, Yogurt
Beverage: Milk, Water, Juice
Answer:
1/36
Step-by-step explanation:
Meal: 4 choices
Side: 3 choices
Beverage: 3 choices
Total number of possible combinations: 4 × 3 × 3 = 36
The specific combination of cheese pizza, apple, and milk is 1 of the 36 possible choices.
p(cheese pizza, apple, milk) = 1/36
Answer:
e
Step-by-step explanation:
We first have to find out how many outcomes there are in total. That means finding out how many meals, sides, and beverages there are.
Meals: cheese pizza, cheeseburger, hotdog, and salad (4)
Sides: banana, apple, and yogurt (3)
Beverages: milk, water, and juice (3)
4 x 3 x 3 = 36
There are 36 possible outcomes.
We need to find the probability that Zoe will choose cheese pizza, an apple, and milk. Those are three outcomes.
The probability is 3/36.
The fraction 3/36 can be simplified to 1/12.

Due to gravity, an object falls 16t squared feet in t seconds. You drop a backpack from a window that is 60 feet above the ground. Will the backpack hit the ground in 2 seconds?
Answer:
No
Step-by-step explanation:
Since gravity falls at a rate of 16 feet per second, t= number of seconds.
if t=2 seconds, you would have the equation 16*2 = fall amount
16*2 =32. Since it is less than 60 feet, the backpack won't hit the ground in 2 seconds

Use the diagram below, if m∠AEC=41°, find each angle measure
Answer:
[14] 139
[15] 90
[16] 41
[17] 49
[18] 139
[19] 131
Step-by-step explanation:
[14] Since m ∠ CEB is vertical with m ∠ AED = 139
[15] Knowing that m ∠FBD = 90 degree then m ∠ CEF = 90 degree
[16] Since m ∠ DEB is vertical to m ∠ADC Thus answer = 41
Note: vertical angles are angles opposite each other where two lines cross.
[17] Since m ∠ FED = 90 degree and m ∠ DEB = 41 then 90 - 41 = 49
[18] To Find m ∠CEB we have to subtract from m ∠ DEB
180 - 41 = 139
[19] Knowing that m ∠ FED = 90 degree and m ∠DEB = 41
Then m ∠ AEF = 90 +41=131

Answer:
This line has a slope of 0, with the equation being y = -4
Step-by-step explanation:
Slope can be found with change in y over change in x
[tex]\frac{-4--4}{-2--3} =\frac{-4+4}{-2+3}=\frac{0}{1} =0[/tex]
Note: We can tell by just looking at the line it will have a slope of 0. A line straight up and down vertically is one with an undefined slope, but a horizontal line has a slope of 0 since there is no incline/decline.
