identify the coefficient, constant, and variable in the expression: - 5 + 8w​

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.

Answer:

x= 12

Step-by-step explanation:

The perimeter of a rectangle is the sum of the lengths of all its sides.

Formula

Perimeter of rectangle= 2(width) +2(length)

Substitute the given information into the formula:

92= 2(2x +3) +2(x +7)

Expand:

92= 4x +6 +2x +14

92= 6x +20

Subtract 20 from both sides:

6x= 92 -20

6x= 72

Divide both sides by 2:

x= 72 ÷6

x= 12

It travels 2404 feet before it is 1,700 feet above ground;

The given question can be represented in the form of equation;          

y = tan(45°)x + c;

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

√(x² + y² = √(1700² + 1700²)                         (∵ it is a right angled triangle;

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

Answer:

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.

As shown in the next figure, AB/CD results in AC/BD.

When a transversal connects two coplanar lines, alternate interior angles are created. They are located on the transverse sides of the parallel lines, but on the inner side of the parallel lines.

∠BCD=∠ABC=50

(By alternating interior angle are equal)

∠ACB=70

∠ACD=∠BCD+∠ACB

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.

The positive integer between 1 and 100 that cannot be represented as a whole percent are 8, 15, 36 and many more.

The class has 99 students.

One student of the class is 1% of the class when rounded to the nearest whole percent. The actual percentage of one student is 1 / 99 × 100 = 100 / 99 = 1.0101010101%

99 of the students represents 100% of the students.

99 / 99 × 100 = 9900 / 99 = 100%

Therefore, the positive integer between 1 and 100 that cannot be represented as a whole percent is as follows:

Step-by-step explanation:

The monthly instalment amounts forms an (a) Arithmetic Progression with common difference 3. (b) Phillips takes 60 months to settle the loan. (c) The sum of the loan is $7410 .

A series of numbers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.

The n-th term of an arithmetic progression is given by:

aₙ = a + ( n - 1 ) d

Where a is the first term and d is the common difference .

(a) Amount of money repaid in the first month = $35

Amount of money repaid in the second month = $38

Amount of money repaid in the third month = $ (38+3) = $ 41

Therefore 41  -38 = 3 and 38 - 35 = 3 . So we see that each monthly instalment is increasing by 3 and the difference between each installment is 3

Therefore the numbers are in an arithmetic progression whose common difference is 3 .

(b) Given the final monthly installment is $ 212

Let us consider that after this is the installment for the n-th month.

∴ aₙ =212 , a= 35 and d=3

Putting the values in the equation of the n-th term of an AP we get:

aₙ = a + ( n - 1 ) d

or, 212 = 35 +(n-1)3

or, 212 - 35 + 3 = 3n

or, n = 60 months

Therefore Phillips takes 60 months to settle the loan.

(c) The formula for the sum of all terms of an AP is given by:

S = (n / 2 ) ( a + aₙ )

or, S = (60/2) × (35+212)

or, S = 30 × 247

or, S = 7410
