Answers

Answer 1
Answer:

Question

At the rate, how much will Mathew be paid for two hours of moving? Round to the nearest cent.

Answer:

exact answer =$19.83

rounded answer = $20

Step-by-step explanation:

3/5 = 0.6, so in 0.6 hours he can do 50% so in 2 hours that has 3 0.6 so 150% and the remaining time is 0.2 hours thats 1/3 of 0.6 so just divide 50% by 3 you'll get around 16.7% so in 2 hours he finished 166.7%

16.7% = 1/3 of 50% = 8.50 = 8.50/3 = 2.83

so 8.50 + 8.50 + 2.83 =

$19.83

50% of what number is 90?

Answers

The answer would be 180 because if 90 is 50% and that's half of 100 then the other 50% would also be 90 and added together that is 180
to get to 100 percent you have to double the number so when you double 90 you get 180

90+90=180.

A recipe calls for 3/4 cup of butter. Angie wants to triple the recipe, but she has only 1 5/8.How much butter must she borrow from a neighbor?

Answers

Let's start out by tripling the original recipe to see how much butter Angie needs.

(3)/(4) * 3 = total
(3* 3)/(4) = total
(9)/(4) = total
2 (1)/(4) = total

So we need 2 (1)/(4) cups of butter, but Angie only has 1 (5)/(8). Let's subtract what Angie has from the total to see how much more she needs.

2 (1)/(4) - 1(5)/(8) = n
(9)/(4) - (13)/(8) = n
we will need the least common denominator for both fractions
(2)/(2) *((9)/(4)) - (13)/(8) = n
(18)/(8) - (13)/(8) = n
(5)/(8) = n

So Angie need (5)/(8) cups more of butter for the recipe.

How do you graph and work problem x+4y=16??

Answers

You have to give values to x or y to create points which can be represented on a system of axis. For example, for x=0 we would get 4y=16, so y=4 => A(0, 4). For y = 0 we would get x=16, so B(16, 0). I attached the graph

Answer: x = 4

How can you use 4s fact to find 7x8? Give the product in your explanation.

Answers

Final answer:

You can use the 4s fact to find the product of 7 and 8 by breaking down 7 x 8 into (4 x 2) x 8, then rearrange to (4 x 8) x 2. Thus, the product of 7 and 8 is 64.

Explanation:

The question relates to using the known multiplication fact of 4 to find the product of 7 and 8. The method involves breaking down 7 x 8 into (4 x 2) x 8, which could be rearranged to (4 x 8) x 2 = 32 x 2 = 64. By using the 4s fact, we first multiplied 4 by 8 to get 32, then multiply the result by 2 to derive the product of 7 and 8.

Final answer:

You can find 7x8 using 4s facts by adding the product of 4x8 to the product of 3x8, which is 32 + 24 = 56.

Explanation:

You can use the 4s facts to find the product of 7x8 by doubling twice. Here's how it works:

  1. First, use the 4s fact, which you should know is 4x8=32.
  2. Then, knowing that 7 is 4+3, you can use the product you already found and the 3s fact (3x8=24), to find 7x8. Add the two products together: 32 (for 4x8) + 24 (for 3x8) = 56.

Therefore, the product of 7x8 is 56.
