Answer: In the pet store, there are 81 fish.
Step-by-step explanation:
We know that:
The ratio of dogs to cats is 4:3
(this means that for every 4 dogs, there are 3 cats)
The ratio of cats to fish is 2:9
(this means that for every 2 cats, there are 9 fish).
Now, we know that there are a total of 24 dogs in the pet store.
Remembering that for each 4 dogs we have 3 cats, we first need to see how many times we have 4 dogs in a total of 24 dogs, this is:
24/4 = 6
So we have 6 times 4 dogs, then we will have 6 times 3 cats, this is a total of:
6*3 cats = 18 cats.
And now we know that for every 2 cats we have 9 fish.
Then we need to see how many times we have 2 cats in a total of 18 cats, this is:
18/2 = 9.
And for each one of these 9 groups, we will have 9 fish, then the total number of fish is:
9*9 = 81 fish
In the pet store, there are 81 fish.

A right triangle has legs with lengths of 6in and 8in. What is the length of the hypotenuse
Answer: 10
Step-by-step explanation:
the formula is √a^2+b^2=c^2
so your equation should look like this √6^2+8^2=c^2
6·6=36
8·8=64
√36+64
√100=10
the hypotenuse or c^2 is 10
20 = -B/0.2

Step-by-step explanation:
A triangle has a base of 10 centimeters and a height of 12 centimeters. A rectangle has a base of 10 centimeters and a height of 12 centimeters.
What are the areas of the figures?
The area of the triangle is
___ cm2.
The area of the rectangle is
___ cm2.
The area of the triangle is
60 cm2.
The area of the rectangle is
240 cm2.
In a two-dimensional plane, an area of triangle is equal to the sum of the areas of its three sides.
To calculate a rectangle's area, count the number of square units that fit within the rectangle's perimeter.
Area of triangle = h x b / 2
Given
h = 12
b =10
hence
A= h x b / 2
= 12 x 10 / 2
= 120 / 2
= 60 cm2
Area of rectangle = l x b
Given
l = 12
b = 10
hence
area of rectangle = l x b
= 12 x 10
= 120 cm2

It snowed 40% more this year than it did last year. If it
snowed 45 inches last year, how much did it snow this
year?
a) In the sketch box, draw a diagram to represent this
situation.
b) In the answer box, write a simplified equation to
represent this situation. Use "y" to represent the
amount of snowfall this year. Your equation should use
decimals.
Answer: y= .4 times 45
it snowed 63 inches
Step-by-step explanation: (I can’t write a diagram on here)
pls mark brainliest
We can conclude that -
The amount snowed this year is 63 inches.A simplified equation to represent this situation -y = 45 + {40% of 45}What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.Given is that it snowed 40% more this year than it did last year. It
snowed 45 inches last year.
{ 1 } -
The amount snowed this year would be -
{x} = 45 + (40% of 45)
{x} = 45 + (40/100 x 45)
{x} = 45 + 18
{x} = 63
{ 3 } -
A simplified equation to represent this situation -
y = 45 + {40% of 45}

A square is cut diagonally into two equal parts. If each part has an area of 50 cm2, then what is the perimeter of each part?
Answer:
30cm
Step-by-step explanation:
Given data
When are square is cut diagonally into two parts
The resulting shape is a triangle
hence the area of the square = 50+50 = 100cm^2
The length of each side of the square = √100= 10cm
likewise the diagonal of the square = 10cm
Hence the perimeter of the resulting triangle= 10+10+10= 30cm
Josh earned $72 less than his sister who earned $93 more than her mom. If they earned a total of $504, how much did josh earn
Answer:
I'm assuming when you say the total of $504 you mean just between Josh and his sister? If so, Josh earned $216 and his sister earned $288
Step-by-step explanation:
Set each person in terms of X. If Josh's sister earned $93 dollars more than her mom, set the equation as (x+93). Since Josh earned $72 less than his sister, he essentially earned 21 dollars more than his mom (x+21). Add those two equations together and set them equal to $504 dollars. Solve for X and solve each equation individually with your answer to find how much each earned.

A particle moves along a line so that its position at any time t > 0 is given by the function s(t) = - t3 + 7t2 - 14t +8 where s is measured in meters and t is measured in seconds. Find the displacement during the first 5 seconds.
Answer:
s(5) = -12
Step-by-step explanation:
s(t) = - t³ + 7t² - 14t +8
Find the displacement during the first 5 seconds.
When t = 5
s(t) = - t³ + 7t² - 14t +8
s(5) = -5³ + 7(5)² - 14(5) + 8
= -125 + 7(25) - 70 + 8
= -125 + 175 - 70 + 8
= -12
s(5) = -12

The bronx zoo opened at 9.00 am. In the first hour 280 people purchased admission tickets. In the second hour 25 percent more people purchased admission people than the first hour . Each ticket cost 16.25. What was the total amount of money paid for all the tickets purchased in the first two hours
Answer:
Total amount paid for tickets in the two hours = $10,237.50
Step-by-step explanation:
Step 1
Ist Hour, 280 tickets were sold at the cost of $16.25
Amount of money made in the first hour= Number of people who purchased ticket x price of a ticket
=280 x 16.25 =$4,550
2nd Hour, 25 % more people purchased ,
which means the total number of people who purchased tickets =
1.25 x 280= 350
Amount of money made in second hour = Number of people who purchased ticket x price of a ticket 350 x 16.25 =$5,687.5
Step 2
Total amount paid for tickets in the two hours = Amount of money made in the first hour +Amount of money made in second hour
=$4,550+ $5,687.5
=$10,237.50
