Answer:

52 tickets

Step-by-step explanation:

7 x 13 = 91

91 - 39 = 52

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

Step-by-step explanation:

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;

                                                                           using Pythagoras theorem)              

               = 2404.16 feet

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.

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.

based on the given value;

we are aware of this;

The adjacent figure displays

AB//CD.

∠BCD=∠ABC=50

(By alternating interior angle are equal)

∠ACB=70

∠ACD=∠BCD+∠ACB

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.

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.

Using proportions, it is found that she travels 60 miles from her house to the VAB on days her colleague drives.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

The first step is finding the fraction corresponding to the 7 miles, hence considering that the total is of 100% = 1 and the fractions given above, we have that:

1 - 5/6 - 1/20 = 1 - 0.8333 - 0.05 = 0.1167.

The 7 miles represent 0.1167 of the trip, hence:

0.1167x = 7

x = 7/0.1167

x = 60.

we get the value of x as 2.4 units when QR is 18 units.

We are given a segment PR.

We are also given that Q is the mid point of the segment.

So, we get that

PQ = QR

Now, we have that

QR = 18 units

PR = 5 x + 6

We have to sind the value of x.

Substituting the values of PR and QR in the equation, we get that:

5 x + 6 = 18

5 x = 18 - 6

5 x = 12

x = 12 / 5

x = 2.4 units

Therefore, we get the value of x as 2.4 units when QR is 18 units.
