By what percent will a fraction increase if its numerator is increased by 60% and its denominator is decreased by 20%?

1 answer:

7 0

Lets just use $\frac{10}{20}$ for an example. If the number is increased by 60% and the denominator is decreased by 20% we get the new fraction being: $\frac{16}{16}$ . Since then new one is equal to 1, and the original is equal to $\frac{1}{2}$ , we see that this manipulation of the fraction causes an increase of 100%.

The cost of 3 burritos is $22.50. If the cost is proportional to the number of burritos ordered,which of the following prices is

Assoli18 [71]

Answer:

A. 7 burritos for $51.50

Step-by-step explanation:

22.50/3=7.50

1 burrito cost $7.50

2 burritos will cost $15.00

2×7.50=15

5 burritos will cost $37.50

5×7.50=37.50

4 burritos will cost $30.00

4×7.50=30.00

However, 7 burritos will not cost $51.50 because 7×7.50=52.50 not 51.50

Plz help me thanks very nuch whoever helped me

Answer:

(1) 56 miles/hour

Step-by-step explanation:

We need to find the average rate of change from t = 2 to t = 9.

At t = 2 hours, d = 106 miles.

At t = 9 hours, d = 498 miles.

The average rate of change in function f(x) from x = a to x = b is

[f(b) - f(a)]/(b - a)

average rate of change from t = 2 to t = 9 =

(498 - 106)/(9 - 2) = 392/7 = 56

Answer: (1) 56 miles/hour

Equality Properties

Step-by-step explanation:

Step 1: Define equation

a + 6a - 14 = 3a + 6a

Step 2: Solve for a

Combine like terms: 7a - 14 = 9a
Subtract 7a on both sides: -14 = 2a
Divide 2 on both sides: -7 = a
Rewrite: a = -7

Step 3: Check

Plug in a into the original equation to verify it's a solution.

Substitute in a: -7 + 6(-7) - 14 = 3(-7) + 6(-7)
Multiply: -7 - 42 - 14 = -21 - 42
Subtract: -49 - 14 = -63
Subtract: -63 = -63

Here we see that -63 is equal to -63.

∴ a = -7 is a solution of the equation.

Step 4: Define equation

-12 - 4x = 8x + 4(1 - 7x)

Step 5: Solve for x

Distribute 4: -12 - 4x = 8x + 4 - 28x
Combine like terms: -12 - 4x = -20x + 4
Add 20x on both sides: -12 + 16x = 4
Add 12 on both sides: 16x = 16
Divide 16 on both sides: x = 1

Step 6: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x: -12 - 4(1) = 8(1) + 4(1 - 7(1))
Multiply: -12 - 4 = 8 + 4(1 - 7)
Subtract: -16 = 8 + 4(-6)
Multiply: -16 = 8 - 24
Subtract: -16 = -16

Here we see that -16 does indeed equal -16.

∴ x = 1 is a solution of the equation.

6)532 with a remainder

BartSMP [9]

Hello Rebelkid2004, 532 with a remainder is, gives remainder 0 and so are divisible by 1, we get factors of 532 numbers by finding numbers that can divide 532 without remainder or alternatively numbers that can multiply together to equal the target number being converted.
