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:

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:

x = 3.125 ft

Step-by-step explanation:

[tex]\frac{5}{x}=\frac{8}{5} \\8x = 25\\x = \frac{25}{8}=3.125[/tex]

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.

Answer:

It's quite simple, let me explain..

Step-by-step explanation:

The median is the middle of a data set, so you would need to find the exact middle of your data set.

If your data set is odd, and has an odd amount of numbers, just get the number exactly in the middle, and that would be your median. But when your data set has an even amount of numbers, it is a bit tricky.

Here's an example:

85, 78, 96, 83, 77

As you can see, this set has an odd amount of numbers, 5 numbers to be exact. The median would be 96 because it is exactly in the middle.

An example of a data set with even numbers would be this:

1, 2, 3, 4

What you would do is add the two numbers in the middle, and divide by two.

In this case, 2 and three are in the middle, so you would add 2 and 3, which is 5. Then you would divide 5 by two which is 2.5

2.5 Would be your median.

Hopefully this made sense, please ask questions if you have any.

8411?

Step-by-step explanation:

I am not entirely sure because you put an x without any spaces soo I don't know if that supposed to be a variable or multiplication sign. If its a multiplication sign then its 8411 because 36+65=99. 99 x 85=8415. 8415 - 4 = 8411.

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.

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.
