Using a system of equations, it is found that the maximum number of people that could be helped with one plane of supplies is: 40,000.

A system of equations is when multiple variables are related, and equations are built to find the values of each variable, according to the relations given in the problem.

For this problem, the variables are given as follows, considering the situation described:

Each food kit helped 8 people and each medicine kit helped 6 people, hence the total number of people helped is given by:

T = 8x + 6y.

This is because we consider that people were helped by only one of them, never both.

Each plane could carry no more than 80,000 pounds. Each food kit weighed 20 pounds and each medicine kit weighed 10 pounds, hence:

20x + 10y = 80000

2x + y = 8000

y = 8000 - 2x.

The maximum volume is of 6000 cubic feet, hence:

x + y = 6000.

y = 6000 - x.

Equaling both equations:

8000 - 2x = 6000 - x

x = 2000.

y = 6000 - x = 4000.

Then the maximum number of people helped is:

T = 8x + 6y = 8 x 2000 + 6 x 4000 = 40,000.

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

this question is horribly phrased.

as far as I can tell after reading this multiple times, this is again looking for the GCF : the greatest common factor.

so, again, prime factor analysis :

168 :

168 ÷ 2 = 84

84 ÷ 2 = 42

42 ÷ 2 = 21

21 ÷ 2 no

21 ÷ 3 = 7

7 ÷ 3 no

7 ÷ 5 no

7 ÷ 7 = 1 finished

168 = 2³×3×7

120 :

120 ÷ 2 = 60

60 ÷ 2 = 30

30 ÷ 2 = 15

15 ÷ 2 no

15 ÷ 3 = 5

5 ÷ 3 no

5 ÷ 5 = 1 finished

120 = 2³×3×5

the GCF is the part of the prime factors both numbers share :

2³×3 = 8×3 = 24

so, they can make 24 fruit cups with identical content and using all the fruits.

these pieces of information were missing in the text.

based on the text without the answer options I was already going for the maximum that each fruit cup has one piece of fruit, and that gives us 168 + 120 = 288 fruit cups max.

No , 1,402 x 71 is 71 is not less than (1,402x 71) -40 .

We have given two numbers 1,402 x 71 and (1,402x 71) -40.

As we can see that in second expression we have subtracted 40 from 1,402 x 71 .So , It is obvious that value of second expression will differ by first expression by 40 .

Hence , 1,402 x 71  is 40 more than (1,402x 71) -40  .

So , it is not possible to have 1,402 x 71 is 71 less than (1,402x 71) -40

Using a system of equations, it is found that you should mix 7 pounds of dried fruit and 3 pounds of nut.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

For this problem, the variables are given as follows:

The mixture has a total of 10 pounds, hence:

x + y = 10 -> y = 10 - x -> x = 10 - y.

Considering the cost per pound of each, and the total cost of 10 x 5.34 = $53.4, we have that:

4.5x + 7.3y = 53.4.

Replacing x = 10 - y, we have that:

4.5(10 - y) + 7.3y = 53.4.

2.8y = 8.4.

y = 8.4/2.8

y = 3.

x = 10 - 3 = 7.

You should mix 7 pounds of dried fruit and 3 pounds of nut.

Since it is launched from ground; c = 0;

thus; y = x is the equation of motion of cannonball;

According to question;  y = 1700 feet

x = 1700 feet;

The distance travelled by cannonball will be

The expression that would be most useful in converting $100 to Japanese Yen is 100 ( 99.30487 Yen / 1)

You can use direct proportion to solve this:

If $1 is to Y99.30487 then what will $100 be equal to:

1         :          99.30487 Yen

100    :                x

Cross multiply to get:

1x = 99.30487 Yen x 100

x = (99.30487 Yen x 100) / 1

Which can be written as:

= 100 ( 99.30487 Yen / 1)

The probability of selecting two male students is 0.47

The probability of selecting two female students is 0.08

Given,

Number of male students in a school club = 26

Number of female students in a school club = 11

Total number of students in the club = 26 + 11 = 37

Number of students selected to represent the club in the student government = 4

We have to find the probability of selecting 2 male and 2 female students:

Then,

The probability of selecting two male students = (26 / 37) × (25 / 37) = 0.47

The probability of selecting two female students = (11 / 37) × (10 / 37) = 0.08

So, we get that

PQ = QR

Now, we have that

QR = 18 units

PR = 5 x + 6
