Answer:
First, set up equations for total cost for both Happy Paws and Woof Watchers.
x= number of hours
y= total cost
Happy Paws
y=3.50x +16
Woof Watchers
y=4.75x+11
4.75x+11=3.50x+16
x=4
You can check your answer by doing the following:
Happy Paws: (3.50)(4)+16= 30
Woof Watchers: (4.75)(4)+11= 30

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?
Answers
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

You have a coin and a dice. Flipping the coin, you can either get heads or tails facing up. There are 6 numbers on the dice, numbered 1-6. What is the probability of flipping tails and getting the numbers 3 or 4 on the dice?
Answers
Answer:
3 = (50.000%)
4 = (66.667%)
Step-by-step explanation:
3 out of 6 = 3/6
4 out of 6 = 4/6
3/6 in decimal form is 0.5
4/6 in decimal form is 0.6666 (the six repeats forever)
0.5 out of 1 is 50%
0.6666 (the six repeats forever) out of 1 is about 66.667%
0.5 = (50.000%)
0.66667 (rounded) = (66.667%)

When using a number line to simplify 175 + (−16), which three choices are correct?A) 175 + (−16) = 159B) 175 + (−16) = 191C) Move 16 units to the left on the number line.D) Move 16 units to the right on the number line.EliminateE) Adding the opposite of a number is the same as subtracting.
Answers
Answer:
B
Step-by-step explanation:
175+(-16) is the same as 175-16, because you can carry the negative. 175-16=159, which is B.
a is correct because you do not add 16, you subtract it. Keep, change, flip.
c is correct because like I said you are subtracting when adding a negative, or making the value less.
e is correct because when adding a negative to a positive, you are subtracting

Answers
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

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%
Answers
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
The way I figure this out is to see what percentage it could be in 100% then multiply that by 5.
To get 500 to 100, divide by 5. Then divide 35 by 5 to match which is 7.
35 is 7% of 500, so 7% of animals were adopted on Saturday

Temperature , , ,
She wants to find the number of ways of combining one level from each of the growth factors. How many ways are there?
Answers
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.

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.

Answers
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]
Therefore, f(12) = 909.03 for the exponential function

Slope can be found with change in y over change in x

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.
