Answer:

6 number treat sacks and

each sack having 5 pencils and 7 smiley face stickers.

Step-by-step explanation:

Given that:

Number of pencils = 30

Number of smiley face stickers = 42

Mrs. MaryAnn wants to divide everything in identical treat sacks so that there are no leftovers.

To find:

The number of greatest number of treat sacks.

Solution:

First of all, we need to find the Highest Common Factor of the two numbers.

Factorization method:

[tex]30 = \underline2\times \underline3\times 5[/tex]

[tex]42 = \underline2\times \underline3 \times 7[/tex]

Here, the common numbers 2 and 3.

So, highest common factor is [tex]2\times 3 = 6[/tex]

If we divide 30 by 6, we get 5 and

If we divide 42 by 6, we get 7

So, if we take 5 pencils and 7 smiley face stickers in one treat sack and if we make 6 such treat sacks then there will be equal division and no leftovers.

Therefore, the answer is:

6 number treat sacks and

each sack having 5 pencils and 7 smiley face stickers.

Answer:

2% : $400

3% : $900

4% : $5400

Step-by-step explanation:

Given that :

Total interest received = 251

Let investment at 2% = x

At 3% = 500 + x

At 4% = 6(500 + x) = 3000 + 6x

Simple interest :

Principal * rate * time

At 2%:

Simple interest = 0.02x

At 3%:

Simple interest = 0.03 * (500 + x) = 15 + 0.03x

At 4%:

Simple interest = 0.04 * (3000 + 6x) = 120 + 0.24x

0.02x + 15 + 0.03x + 120 + 0.24x = 251

0.29x + 135 = 251

0.29x = 116

x = 116 / 0.29

x = 400

Amount invested at 2% = x = $400

Amount invested at 3% = $500 + x = 500 + 400 = 900

Amount invested at 4% = 3000 + 6x = $3000 + 6(400) = $3000 + $2400 = $5400

Answer:

B. (x - 3²)(y-6)

Step-by-step explanation:

 Find the expression with a value of 30;

  when x  = -1 and y = 3:

    A.  (x - 3²).y-6

            (-1 - 9).3-6 = -10 x 3 -6  = -30 - 6 = -36

  B.  (x - 3²)(y-6)

           ( -1 -3²)(3 - 6) = (-1 -9)(-3) = 30

 C.  x - 3² . (y-6) = -1 - 9.(3-6)

                          = -1-9.-3

                          = -1 - 9 x -3

                          = -1 + 27

                          = 26

D. x - 3².y-6 = -1 - 9. 3 - 6

                    = -1 - 27 - 6

                    = -34

Answer:

30% of people surveyed were satisfied with the car.

Step-by-step explanation:

We are given:

Total participants in survey= 2800

People satisfied with car = 840

We need to find percent of the people surveyed were satisfied with the car.

The formula used is: [tex]\frac{People \ satisfied \ with \ car}{Total \ participants \ in \ survey} \times 100[/tex]

[tex]=\frac{840}{2800}\times 100\\=30\%[/tex]

So, 30% of people surveyed were satisfied with the car.

Answer:

-2/1

Step-by-step explanation:

Answer:

The multiplicative inverse is 2

Step-by-step explanation:

In mathematics, we call the number 1 the multiplicative identity because if we multiple any number by 1, we get that same number as our answer. A multiplicative inverse of a number, x, is a number y, such that if we multiply x times y, then we get the multiplicative identity. That is, x × y = 1.

Answer:

Step-by-step explanation:

Answer:

425 miles

Step-by-step explanation:

Divide 510 by 60 to get miles per minute and then multiply by 50 to get miles in 50 minutes

The airplane move 425 miles in 50 minutes.

Given:

Speed= 510 mph

Time= 50  min = 50/60 hour.

So, speed= Distance / Time

510 = Distance / (5/6)

510 x 5/6 = Distance

Distance = 425 miles

Hence, the Airplane travel 425 miles.
