In a fish tank, 50% of the fish are clown fish, 1/3 are angel fish and the rest are goldfish. There are 33 clown fish in the fish tank. (b) How many goldfish are there in the fish tank?
Answer:
11 gold fish
Step-by-step explanation:
We are told that
In a fish tank, 50% of the fish are clown fish and there are 33 clown fish in the fish tank.
Let the total number of fishes in the tank be = x
Hence,
50% of x = 33
50/100 × x = 33
50x/100 = 33
Cross Multiplying
50x = 33 × 100
x = 33 × 100/50
x = 66 fishes
Hence, the total number of fishes in the tank = 66 fishes
1/3 are angel fish
The number of angel fishes are
1/3 × 66 fishes = 22 angel fish
•The rest are goldfish. How many goldfish are there in the fish tank?
The number of gold fish is calculated as:
Total number of fishes -( Number of clown fish + Number of angel fish)
= 66 - (33 + 22)
= 66 - 55
= 11
Therefore, the number of gold fish is 11
Answer:
Step-by-step explanation:
1/33 because its 33 goldfish

Computation:
Circumference of semi circle = πr + Diameter
Circumference of semi circle = (22/7)(28) + 28
Circumference of semi circle = 88 + 28
Circumference of semi circle = 116 cm

Answer:
C) a = 3√10; b = 3√5
Step-by-step explanation:
The side ratios in an isosceles right triangle are 1 : 1 : √2. This is a fact worth remembering. You know the triangle is isosceles because both acute angles are 45°, which means both legs are the same length.
If the leg lengths are 1, the Pythagorean theorem tells you the hypotenuse is ...
c^2 = a^2 + b^2 . . . . . . for legs a, b, and hypotenuse c
c^2 = 1^2 + 1^2 = 2
c = √2
This tells you the leg : leg : hypotenuse ratios are as shown above.
__
What that means here is that b = 3√5, the same length as the one shown. It also means that ,,,
a = (3√5)(√2) = 3√(5·2)
a = 3√10
The only answer choice with the correct value of 'a' is (C).
a = 3√10, b = 3√5

Boris filled his gas tank three times last week. Here are the amounts of gas he bought (in gallons).
9.94, 1, 19.1
What is the total amount of gas Boris bought last week?
Answer:
30.04
Step-by-step explanation:
You could do this the simple way which is to first grab two numbers in any order and add them together, and after you do that you can add the result to the remaining number or numbers that remain. 9.94 plus 1 is 10.94, and 10.94 plus 19 is 29.94, lastly the .1 from the 19 which finally leads us to the answer of 30.04 gallons that Boris bought last week

At the beginning of summer, Mark has $200 in savings and Ryan has $350. The brothers have mowing jobs set up for the summer. Because Mark is older, he receives $20 for each mowing job and Ryan receives $15. The brothers’ parents pay for the fuel used to mow, so all of the money the brothers earn goes to savings.
Write two equations, one for Mark and one for Ryan, to represent the money in savings (s) based on the number of mowing jobs (j) Mark and Ryan do.
Determine the number of mowing jobs it takes for Mark to have the same amount in savings as Ryan does. Show your work.
Answer:
30 jobsStep-by-step explanation:
Mark
Initial amount - $200Earning - $20*jSaving is: S = 20j + 200Ryan
Initial amount - $350Earning - $15*jSaving is: S = 15j + 350If they get same saving, then the equations will be equal:
20j + 200 = 15j + 35020j - 15j = 350 - 2005j = 150j = 150/5j = 30The answer is 30 mowing jobs

Here are three stories:
• A family buys 6 tickets to a show. They also pay a $3 parking fee. They spend $27 to see the
show.
• Diego has 27 ounces of juice. He pours equal amounts for each of his 3 friends and has 6
ounces left for himself.
• Jada works for 6 hours preparing for the art fair. She spends 3 hours on a sculpture and
then paints 27 picture frames.
Here are three equations:
• 3x + 6 = 27
• 6x +3=27
• 27x + 3 = 6
a. Decide which equation represents each story. What does x represent in each equation?
b. Find the solution to each equation. Explain or show your reasoning,
c. What does each solution tell you about its situation?
Answer:
1)
a) 6x+3 = 27
b) x=4
c) We know that x is price of each ticket, so The price of each ticket is $4. They bought 6 tickets, so total cost of ticket = 24 and $3 for parking so, total money spent = $27.
2)
a) 3x + 6 = 27
b) x= 7
c) We know that x is amount of juice poured, so 3 friends of Diego will get 7 ounces of Juice, while Diego will get 6 ounces of juice.
3)
a) 27x + 3 = 6
b) x= 1/9
c) We know that x is time spend on each picture, so Jada spend 1/9 hour on each picture
Step-by-step explanation:
1. A family buys 6 tickets to a show. They also pay a $3 parking fee. They spend $27 to see the show.
a) Decide which equation represents each story. What does x represent in each equation?
Let x be price of one ticket.
The equation will be: 6x+3 = 27
b. Find the solution to each equation. Explain or show your reasoning,
Now solving the equation:
6x+3=27
6x=27-3
6x=24
x=24/6
x=4
So, we get x = 4
c. What does each solution tell you about its situation?
We know that x is price of each ticket, so The price of each ticket is $4. They bought 6 tickets, so total cost of ticket = 24 and $3 for parking so, total money spent = $27.
2. Diego has 27 ounces of juice. He pours equal amounts for each of his 3 friends and has 6 ounces left for himself.
a) Decide which equation represents each story. What does x represent in each equation?
Let x be amount of juice poured.
The equation will be: 3x+6 = 27
b. Find the solution to each equation. Explain or show your reasoning,
Now solving the equation:
3x+6=27
3x=27-6
3x=21
x=21/3
x=7
So, we get x = 7
c. What does each solution tell you about its situation?
We know that x is amount of juice poured, so 3 friends of Diego will get 7 ounces of Juice, while Diego will get 6 ounces of juice.
3. Diego has 27 ounces of juice. He pours equal amounts for each of his 3 friends and has 6 ounces left for himself.
a) Jada works for 6 hours preparing for the art fair. She spends 3 hours on a sculpture and then paints 27 picture frames.
Let x be time spend on each picture frame.
The equation will be: 27x+3=6
b. Find the solution to each equation. Explain or show your reasoning,
Now solving the equation:
27x+3=6
27x=6-3
27x=3
x=3/27
x=1/9
So, we get x = 1/9
c. What does each solution tell you about its situation?
We know that x is time spend on each picture, so Jada spend 1/9 hour on each picture
