1/4 is larger than 5/8 by how much?
( fraction)

Answers

Answer:

3/8

Step-by-step explanation:

Step 1: Multiply the denominator and the numerator of 1/4 by 2 to get a common denominator between the two. (1/4 and 5/8 is now 2/8 and 5/8)

1*2= 2; 4*2= 8, so you get 2/8 (which is equal to 1/4)

Step 2: When you get 2/8, subtract:

5/8 - 2/8 = 3/8

And... since 2/8 is equal to 1/4, 3/8 is the answer :)

Hope this helps :)

what is the price of you pizza with all the toppings?

Answers

Each answer is under each Part

1. What is the price of you pizza with all the toppings?                                

$16

The pizza costs 12 dollars, and each topping costs 1.75 dollars, there are 4 toppings, so it's 12 + 1.75*4 = 12 + 4 = 16 dollars.

2. How much will you pay in tax?                                                                

$0.80

It costs 16 dollars and tax is 5%, so 5% of 16. 16*5% = 16*0.05 = 0.8, so 0.8 dollars, or $0.80

3. What is the total cost including tax?                                                    

$16.80

Add the cost of the pizza with the tax, 16 + 0.8 = 16.8, $16.80

4. How much will each of you need to pay to cover the total price?

$4.20

There are 4 people total, You and 3 friends, so divide the total cost by 4, 16.80/4 = 4.2, so $4.20

A right triangle has legs of 30m and 40m. What is the PERIMETER of the triangle?

choices:
A.) 120m

B.) 70m

C.) 1200m

D.) 50m

Answers

Answer:

A

Step-by-step explanation:

We know that we are dealing with a right triangle. Look at the legs given to us, 30m and 40m. That looks familiar doesn't it? In fact, this quite resembles the 3-4-5 special right triangle.

We can simply scale the legs by 10 to find the last side of the triangle.

[tex]3*10=30\\4*10=40[/tex]

and therefore, the last side of the right triangle must be:

[tex]5*10=50[/tex]

Great! Now we have all the sides of the right triangle. We just have to add them up:

[tex]30+40+50=120[/tex]

Therefore, the perimeter of the triangle is 120m. A.
