Sam's two new aquariums each hold exactly 200 gallons of water.One aquarium will hold small fish and the other will hold large fish. Now he needs new fish for his aquarium.He will buy 5 small fish for every 10 gallons of water in the aquarium.He will buy 8 large fish for every 40 gallons of water in the aquarium.What is the total number of fish Sam will have? What will be the ratio of Sam's small fish to large fish? Could the ration be 25 small fish for every 10 big fish?

Answers

Answer 1

Answer:

100 small fish will be in 200 gallons of water. 40 large fish will be in 200 gallons of water.

Step-by-step explanation:

200/10=20

20*5=100 small fish

200/40=5

5*8=40 large fish

100+40=140 total fish

small fish/large fish=100/40=10/4=5/2 is the ratio

What is the height, x, of the equilateral triangle?

Answers

Given:

The figure of an equilateral triangle with side length 14 in.

To find:

The height x of the equilateral triangle.

Solution:

We know that the height of an equilateral triangle is:

[tex]h=\dfrac{\sqrt{3}}{2}a[/tex]

Where, a is the length of side of the equilateral triangle.

It is given that the height of the triangle is [tex]x[/tex].

Putting [tex]a=14,h=x[/tex] in the above formula, we get

[tex]x=\dfrac{\sqrt{3}}{2}(14)[/tex]

[tex]x=\sqrt{3}(7)[/tex]

[tex]x=7\sqrt{3}[/tex]

Therefore, the height of the triangle is [tex]x=7\sqrt{3}[/tex].

Tanya has a $50 gift card to spend on Amazon. She wants an airpod case cover for $12.
She also wants to buy some bracelets for $9.50 each. How many bracelets can she buy
without going over?

Answers

Answer:

She can buy 3 bracelets.

Step-by-step explanation:

$50 (Total price) - $12 (Airpod case) = $38

$38 - $9.50 (Bracelets) = $28.5

$28.5 - $9.50 = $19

$19 - $9.50 = $9.5

Liz goes on holiday to South Africa

Liz wants to change £850 into south african rand
she wants to get as many 200 rand notes as possible

The exchange rate is £1=18.53 rand

Work out the greatest number of 200 rand notes that liz can get for £850

Answers

Answer:

82 notes

Step-by-step explanation:

The computation is shown below:

Given that

£1= 18.53 rand

and since Linz has £850 so he would get the equivalent of

= $890 ×  18.53

= 16,491.7 rands

Now he wants the 200 rand notes so we considered it as the  highest note

So, the greatest no of 200 notes would be

= 16,491.7 ÷ 200

= 82.45

= 82 notes

Galaxy c is the farthest

Answer: Galaxy c is the farthest

Step-by-step explanation:

The difference of c and 7 is less than or equal to 17.

Answers

| c - 7 | 《 17

- 17 《 c - 7 《 17

add sides 7

- 17 + 7 《 c - 7 + 7《 17 + 7

simplification

- 10 《 c《 24

Answer:

c - 7 ≤ 17

c ≤ 24

Step-by-step explanation:

The difference of c and 7 can be written as c - 7 or 7 - c.

Now, since c - 7 is less than or equal to 17, you need to add ≤ to imply that it's less than or equal to 17.

As always, write the 17 on the other side. Now you have an inequality.

If you just need the equation, it's c - 7 ≤ 17.

But if you want to solve for c, it would be c ≤ 24.

(bring the like terms together and isolate c.)

what’s the perimeter?
The perimeter of a triangle Park shown on the rate is 13 X -7 what is the missing length

Answers

Answer:

The length of the missing side is 7x-5

Step-by-step explanation:

Here, we want to get the value of the missing length

Mathematically, the perimeter of a triangle can be obtained by adding the lengths of its sides

So by subtracting the sum of the lengths of the two given sides from that of the perimeter, we get the length of the third side of the triangle

mathematically, we have this as;

13x-7 -(4x + 2 + 2x-4)

13x-7 - (4x + 2x + 2-4)

= 13x-7 - (6x -2)

= 13x -7 -6x + 2

= 13x-6x -7 + 2

= 7x -5

Each box has 10 brooms. Each broom is sold for $ 15

The charity earns $ 50 profit for each box of brooms.

First, we need to calculate the total revenue per box:

Total revenue per box= 10*15= $150
