MP =8
Step-by-step explanation:
QR = 1/2 MP
76 -8x = 1/2 (89 - 9x) Multiply both sides by 2
152 - 16x = 89 - 9x Subtract 89 from both sides
152-89 - 16x = - 9x Add 16x to both sides.
63 - 16x +16x = 16x - 9x
63 =7x Divide by 7
x = 63/7
x = 9
MP = 89 - 9*9
MP = 8

ratio of seahorses to total number of fish?
Answers
Answer:
18 : 26
Step-by-step explanation:
It is very easy, angel fish and clown fish are fish, so once you add them up you get 26. The seahorses are 18 and we are supposed to make them S:F. Therefore you put the seahorses first and the fish second, so you get the answer 18:26

Answers

Step-by-step explanation:
The data represent a linear function because there is a common difference of -9.
What is a linear function?The term linear function refers to two distinct but related notions: In calculus and related areas, a linear function is a function whose graph is a straight line, that is, a polynomial function of degree zero or one.
Given, the table, we need to see whether the data in the table represent a linear function or an exponential function.
From the table, we have the following highlight :-
As the values of x increase by 1, the values of y decrease by 9
A decrement of 9, means -9
This means that, the common difference is -9.
Only a linear function can have a common difference.
Hence, the true statement is (b)

Amy wrote a 10 sided die numbered one through 10 what is the probability that she will hold a number divisible by four
Answers
Answer:
2/10 or 20%
Step-by-step explanation:
Because 4 and 8 are the only numbers 1-10 that are divisible by four.
This would give Amy a 2/10 chance of rolling a number divisible by 4.
To turn 2/10 into a percent, the denominator has to be 100 so if you multiply 10 by 10 you will get 100, you will also have to multiply 2 by 10 to get 20 and you will get 20/100
20/100 is equal to 20%
Therefore your answer would be 2/10 or 20%

The population of cats in a town increased by 25% from Year 1 to Year 2. The population of cats in Year 2 is 60.
Answers
Answer: See explanation
Step-by-step explanation:
Your question isn't complete but I guess that you want to find the population of the cats in Year 1. This will be represented by x. Therefore,
x + (25% × x) = 60
x + (0.25 × x) = 60
x + 0.25x = 60
1.25x = 60
x = 60/1.25
x = 48
The population of cats in year 1 is 48

Marty has a driveway that is 200 feet long. The tires on her car have a diameter of 18 inches. What is the fewest number of tire rotations a tire will make tot travel the entire distance of the driveway?
Answers
The the fewest number of tire rotations is 42 to travel the entire distance of the driveway.
It is given that the driveway that is 200 feet long and the tire diameter is 18 inches.
It is required to find the fewest number of tire rotations a tire will make to travel the entire distance of the driveway.
What is a circle?It is defined as the combination of points that and every point has an equal distance from a fixed point ( called the center of a circle).
Driveway length = 200 feet
Diameter of the tire = 10 inches
For converting it to feet divide by 12.
Now the diameter of tire = 18/12 = 1.5 feet
Radius of the tire = 0.75 feet
We know the perimeter of the circle:
[tex]\rm P = 2\pi r[/tex]
P = 2(π)(0.75)
P = 4.71 feet ( π =3.14 and P = 0.75)
[tex]\rm number \ of \ tire \ rotations = \frac{Driveway \ length}{Perimeter \ of tire}[/tex]
[tex]= \frac{200}{4.71}[/tex]
Number of tire rotation = 42.462 ≈ 42
Thus, the the fewest number of tire rotations is 42 to travel the entire distance of the driveway.

principal= $9000
Rate= 12/100=0•12
Time=5years
Simple interest =PRT
= 9000× 0•12 × 5
