The chess clubcab have at most 36 members. The are 3 times as many boys as girls in the chess club. Which inequality could be used to determine the possible number of girls, x, in the chess club?

Answers

Answer:

The number of girls is at most 9 girls

y ≤ 9

Step-by-step explanation:

The chess clubcab have at most 36 members.

At most means : Less than or equal to 36 members and it is represented by the inequality = ≤

The are 3 times as many boys as girls in the chess club.

Boys = x

Girls = y

Hence,

x = 3y

Which inequality could be used to determine the possible number of girls, x, in the chess club?

Therefore,

x + y≤ 36

3y + y ≤ 36

4y ≤ 36

y ≤ 36/4

y ≤ 9

Girls = y

All four arms of a mechanical jack are the same​ length, and they form a parallelogram. Turning the crank pulls the arms​ together, raising the top of the jack. How high is the top of the jack when the crank is 5 inches off the​ ground? Explain.

Answers

Answer:

10 inches

Step-by-step explanation:

The top of the jack is 10 inches from ground.

What is parallelogram?

A parallelogram is a two-pair quadrilateral with parallel sides. A parallelogram has opposite sides that are the same length and have opposite angles that are the same size. Additionally, the interior angles on the same transversal side are supplemental. 360 degrees are the sum of all the interior angles.

A parallelepiped is a three-dimensional shape with parallelogram-shaped faces.

Given Jack is in shape of parallelogram,

height of crank of jack from ground  = 5 inches

to find the distance from ground to top of jack

since crank is at centre of jack and bottom  to top of jack makes the diagonal of parallelogram,

distance from crank to top of jack is 5 inches,

because The two diagonals cut across one another. The parallelogram is divided into two congruent triangles by each diagonal.

total length from ground is 5 + 5 = 10 inches

Hence length from ground to top of jack is 10 inches because diagonals bisect each other.

What is a number that when you multiply it by 0.9 and
subtract 6.3 from the product, you get 4.5?

Answers

0.9x12=10.8,, 10.8-6.3=4.5. The number is 12

The number that when you multiply it by 0.9 and subtract 6.3 from the product, you get 4.5 is 12.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

Let the number be x.

According to the problem, we have:

0.9x - 6.3 = 4.5

Adding 6.3 to both sides, we get:

0.9x = 10.8

Dividing both sides by 0.9, we get:

x = 12

Therefore,

The number we're looking for is x = 12.

x + 3y = 2
-x + 2y = 3
Can somebody help me?

Answers

x = -1 ; y = 1

x + 3y = 2, isolate x by subtracting 3y from both sides. Now that x is alone (because x = -3y + 2) take -3y + 2 and plug it into the second equation.

-(-3y + 2) + 2y =3 ; multiply what’s in the parenthesis by -1. It now is 3y -2 + 2y =3, add the common variables ( 3y + 2y) and you now have 5y-2=3. Move the 2 to the other side by adding it to both sides, you now have 5y=5, divide both sides by 5 and y=1.

Take any equation and plug y in for 1 to get x.

For example, (in the second equation), -x+2(1)=3, multiply 2 by 1 and you’re left with -x+2=3. Subtract 2 on both sides and you have -x=1, now divide both sides by -1 and x=-1.

You can check your work by plugging in the x and/or y values into the equations

42 is our final answer so that should be by itself.

If something is being decreased by 9, that means that we are taking away 9 from something so it should be m - 9.

2400 people attended a basketball game. 696 of the people attending supported the home team, while 1704 supported the visiting team. What percentage of people attending supported the home team?

Answers

Answer:

0.29 or 29 percent I put it on god

Step-by-step explanation:

The percentage of people attending supported the home team is 29%.

What is percentage?

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion therefore refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Given, 2400 people attended a basketball game. 696 of the people attending supported the home team, while 1704 supported the visiting team.

From the general formula of percentage:

percentage = value/ total value * 100

Since, Out  of 2400 only 696 supported the home team

thus,

Percentage = 696/2400*100

Percentage = 29%

Therefore, 29% percentage of people attending supported the home team.
