Answer:
12 = 5 + x
Step-by-step explanation:
Total fish in the aquarium = 12
Number of guppies fish = 5
Number of other fishes = x
Total fish in the aquarium = Number of guppies fish + Number of other fishes
12 = 5 + x
Subtract 5 from both sides
12 - 5 = 5 + x - 5
7 = x
x = 7
Number of other fishes = x = 7

Find RT please and thank you.
RQ × RP = RS × RT
9 × ( 9 + 13 ) = 11 × RT
9 × 22 = 11 × RT
Divide sides by 11
9 × 22 / 11 = 11 × RT / 11
Simplification
9 × 2 = RT
RT = 18
Answer: RT=18
Step-by-step explanation: I’m going to be using this formula: RQ•RP=RS•RT
9•22=198
ST=7
11•18=198
Therefore RT=18
A runner ran 20 miles in 150 minutes.
If she runs at the same speed,
a. How long would it take her to run 6 miles? ___minuets
b. How far could she run in 15 minutes?
___miles
C. How fast is she running in miles per hour?
miles per hour___
d. What is her pace in minutes per mile?
minutes per mile___
Answer:
a) 45 minutes
b) 2 miles
c) 8 miles per hour
d) 7.5 minutes per mile
Step-by-step explanation:
a) (150/20) x 6 = 45 minutes
b) (20/150)(15) = 2 miles
c) (20/150)(60) = 8 miles per hour
d) 150/20 = 7.5 minutes per mile
Answer:
Use ratios and cross multiplication to solve this
20 miles ⇔ 150 minutesa.
20 miles ⇔ 150 minutes6 miles ⇔ x minutes20x = 150*6x = 900/20x = 45 minutesb.
6 miles ⇔ 45 minutesx miles ⇔ 15 minutesx = 6*15/45x = 2 milesc.
2 miles ⇔ 15 minutes x miles ⇔ 1 hour = 60 minx = 2*4 = 8 miles per hourd.
2 miles ⇔ 15 minutes 1 mile ⇔ x minutesx = 15/2 = 7.5 minutes per mileThe function f(x) = 300(1 − 0.05)x models a population of sharks after x years. What will the population be in 7 years?

A college professor teaching a class of Psychology gives the following grades during Fall semester: 15% A’s, 20% B’s, 40% C’s, and 10% D’s. The remainder of the students receive an F.
What is the probability that a randomly selected student does not earn an A in this class?
Answer:
85%
Step-by-step explanation:
Because we can see that only 15% of the class obtained A's, and the question only refers to those that did not receive A's, we can subtract the 15% of the 100% whole to get 85%. This can also be written as 85/100 or 17/20(simplified).
Tammy rents a storage shed. The storage shed is in the shape of a rectangular prism with measurements as shown. A rectangular prism has a length of 10 feet, height of 9 feet and a width of 9 feet. Select the phrase and number from the drop-down menus to correctly complete each sentence. Tammy can find the volume of the storage unit by Choose... . To completely fill the storage shed, Tammy would need Choose... Unit boxes that each measure 1 cubic foot.
Answer:
Finding the product of 9, 10 and 9 ; 810
Step-by-step explanation:
Given that :
Length = 10 feets
Width = 9 feets
Height = 9 feets
The volume of a rectangular prism is obtained by :
Length * width * height
The volume could be obtained by taking the product of 10, 9 and 9
Hence, the volume of the rectangular prism is :
(10 * 9 * 9) feet³ = 810 feet³
Number of 1 feet³ boxes = 810 feet³ / 1 feet³ = 810
In a survey of 292 students, about 9.9% have attended more than one play. Which

play?
3 students
10 students
20 students
30 students
Witch one
Answer:
30
Step-by-step explanation:
So we know that there are 292 people and 9.9% attended one play so you just find 10% of 300(approximated) which is the same thing as 30.

Gail runs a taxi.
Her running costs are £95 per day.
She charges £1.40 per mile travelled.
On Tuesday she carried passengers for a total of 50 miles.
What was her total loss?
Answer:
Her total loss was £25
Step-by-step explanation:
Here, we want to get the value of total loss
What we have to do here is to subtract the amount made from the running cost
From the question, we have the amount made as;
£1.40 * 50 = £70
So we have the loss as,
70-95 = -£25

A sapling that started out 13.63 inches tall grew 2.41 inches per year. How tall was the sapling when it was 14 years old?
Answer:
47.37 Inches
Step-by-step explanation:
We start by assuming that we're at zero years when the tree is at 13.63 inches. We then ignore that height, and look at the rate of growth, which is 2.41 in / year.
The question asks how tall the tree is when it's 14 years old, so we multiply 2.41 inches / year by 14 years to get 33.74 inches.
The final step is to add that 33.74 onto the original 13.63 to get a new total of 47.37 inches when the sapling is 14 years old.

A3 Math gr6 20-21 Form O Online 21 of 34Item s Ali writes the expression "half of the sum of $9$ and a number." Write an algebraic expression that is equivalent to Ali's expression. Write a second algebraic expression that is different from, but equivalent to, your first expression.
Answer: See explanation
Step-by-step explanation:
We are informed that we should write a equation that represents the expression "Ali writes the expression "half of the sum of $9 and a number.".
Let the number be represented by x. The first equation based on the information given will be:
= 1/2(9 + x)
The second equation will be:
= (9 + x)/2

Linear y=mx+b Line
a. y=x b. y= -2/3x -4
Answer:
Every straight line can be represented by an equation: y = mx + b. ... The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.
Step-by-step explanation:
