Step-by-step explanation:
Scott took 7* math tests in one semester. His scores were 89 , 73 , 84 , 91 , 87 , 77 , 94.
Find the mean. To solve for the mean, add all the scores together, and divide by the amount of tests he took:
(89 + 73 + 84 + 91 + 87 + 77 + 94)/7
(595)/7 = 85
Scott's mean test score is 85.

Milo drinks 2/5 of a bowls of water in 1/3 of an hour. How many hours will it take Milo to drink an entire bowl of water?
Answer:
It would take Milo 5/6 of an hour to drink an entire bowl of water.
Step-by-step explanation:
In this case, you can use a rule of three to find how many hours it will take to drink 1 bowl of water given that 2/5 of a bowl of water takes 1/3 of an hour:
2/5 of a bowl → 1/3 of an hour
1 bowl → x
x=(1*1/3)÷2/5
x=1/3÷2/5
x=(1*5)/(3*2)
x=5/6
According to this, the answer is that it would take Milo 5/6 of an hour to drink an entire bowl of water.

The ratio of dogs to cats in the neighborhood was 3 to 7. If a total of 210 dogs and cats were in the neighborhood, how many cats were there? Complete the statement by providing the correct response in number form.
Answer:
147 cats
Step-by-step explanation
There are 3 dogs/ 7 cats
3x + 7x = 210
10x = 210
210 ÷ 10 = 21
Therefore,
x = 21.
dogs would be 3x (3 x 21) = 63
cats would be 7x (7 x 21) = 147

Math honestly shouldn't exist-
Answer:
This isn't really that hard... ∠A = 166°
Step-by-step explanation:
Because ∠A and ∠B are corresponding angles of a set of parallel lines, that means they are equal, so you can use this equation to solve for x:[tex]7x+40=3x+112[/tex] ⇒ [tex]4x=72[/tex] ⇒ [tex]x=18[/tex]. To find ∠A, just substitute x for 18 and you'll get that ∠A equals 7 * 18 + 40 = 126 + 40 = 166°.

Find the missing height of the parallelogram described. b = (x + 4) yd, (blank text) yd, (5x + 20) yd2
Answer:
5yards
Step-by-step explanation:
Area of the parallelogram = Base * Height
Given
Area = (5x+20)yd²
Base = (x+4)yd
Required
height
Substitute into the formula
5x+20 = x+4 * Height
Height = 5x+20/x+4
Height = 5(x+4)/x+4
X+4 cancels out to have;
Height = 5
Hence the height of the parallelogram is 5yards

Can the sides of a triangle have lengths 1, 2, and 5? A. Yes B. No
Answer:no
Step-by-step explanation:
Answer:
No
Step-by-step explanation:
It can't have a side of 1, 2, and 5 because any two sides of a triangle must be larger then the 3rd side.
1 + 2 = 3 is not larger then the 3rd side which is 5
how do you know of an exponential fuction is reflected across the x-axis?
Answer:
Step-by-step explanation:
A reflection over the x-axis changes all the y-values. The reflection is modeled as -f(x)
For example:
[tex]\sqrt{x}[/tex] would look like --[tex]\sqrt{x}[/tex] .
If the negative sign is outside of the bracket ( what it's called sorry), then it is a reflection over the x-axis
However if the negative sign was inside the bracket: [tex]\sqrt{-x}[/tex] then this would be a reflection over the y axis.
Hope this helps!
