Answers

Answer 1

Answer:

45/8

Step-by-step explanation:

You divide 3 3/4 by 1 1/2

First turn the mixed numbers into improper fractions.

Multiply the whole number by the denominator then add the numerator. Keep the denominator the same.

3 3/4:

3 x 4 = 12

12+3

= 15/4

1 1/2 :

1 x 2= 2

2+1

= 3/2

now you're dividing 15/4 by 3/2

My teacher always taught me KFC:

Keep, change flip

Keep:

Keep the first fraction don't change it. 15/4 stays the same.

Change:

Change the division sign to multiplication.

Flip:

Flip the last fraction to its reciprocal.

In this case instead of it being 3/2, it will be 2/3

Next

Multiply straight across

15/4 x 2/3

15 x 2 = 30

4 x 3 = 12

30/12

Simplified would be 5/2 as an improper fraction

2 1/3 as a mixed number

I am so sorry but I don't know how to explain the 2nd question without it making any sense, I hope someone else can for you! I hope I helped with the first one!

Answer 2

Answer:

Step-by-step explanation:

15/4 x 2/3

15 x 2 = 30

4 x 3 = 12

30/12

Simplified would be 5/2 as an improper fraction

2 1/3 as a mixed number

Which graph represents the inequality 2.5 is less than the product of −0.5 and a number?

Answers

Answer: The mathematical statement is given as

"2.5 greater than the product of -0.5 and a number"

Product means times

So, we have the following representation

"2.5 greater than the product of -0.5 and a number" ⇒ 2.5 greater than -0.5 * a number

Let the number be x

So, we have

"2.5 greater than the product of -0.5 and a number" ⇒ 2.5 greater than -0.5x

Greater than is represented by >

So, we have

"2.5 greater than the product of -0.5 and a number" ⇒ 2.5 > -0.5x

Next, we plot the graph of the inequality expression

Answer:

P = 37 in

Step-by-step explanation:

since the base angles of the triangle are congruent then the triangle is isosceles with the 2 legs congruent , then

3x - 2 = 2x + 4 ( subtract 2x from both sides )

x - 2 = 4 ( add 2 to both sides )

x = 6

then

2x + 4 = 2(6) + 4 = 12 + 4 = 16

3x - 2 = 3(6) - 2 = 18 - 2 = 16

the perimeter (P) is the sum of the 3 sides , then

P = 16 + 16 + 5 = 37 in

The answer for P is 37 in.

The cost of a trail mix at the grocery store is normally $12 per pound but now the price has increased by 30%. What is the price per pound of trail mix now that the price has increased?

Answers

Answer:

15.6

Step-by-step explanation:

The price of trail mix has increased by $12 * 30/100 = $<<12*30/100=3.6>>3.6.

So the price per pound of trail mix now is $12 + $3.6 = $<<12+3.6=15.6>>15.6.

The required new price of the trail mix is $15.6 .

What is percentage?

Percentage is a measurement to find value of given number out of hundred.

Given that,

The normal cost of trail mix at the grocery store = $12 per pound.

Als0, the price of the trail mix increased by 30%.

To find the price of trail mix after increasing the price,

Use percentage property,

Let the initial price was 100 %

So after increasing 30%, the new price becomes 130%.

The new price = 12 x 130% = 12 x 130 / 100 = 1560/100 = 15.6

The increased price of the trail mix is $15.6.

What is a fraction?

A numerical value that designates a portion of a whole is used to represent fractions. A fraction is a component or section taken from a whole, which can be any number, a certain amount, or an object.

Given:

Bob ate only 18 chocolate bars out of a new box of chocolates and left 2/5,

Calculate the total chocolate as shown below

Total chocolate = T

T = 18 + 2 / 5 × T

T - 2 / 5T = 18

3 / 5 T = 18

3T = 18 × 5

T = 90 / 3

T = 30

Therefore, the chocolates were in the full box, if Bob ate only 18 chocolate bars out of a new box of chocolates and left 2/5 is 30.
