Proportionately, if 32% represent students who played football, and the total number of them is 180, the total students in the group is 563.

Proportion is the ratio of two quantities equated to each other.

Proportion is a fractional value and we represent proportional values as between zero and one.

Answer:

228 ft^2

Step-by-step explanation:

1/10 of the given dimensions are 9.5 ft by 8 ft by 3 ft.

The volume of the model is thus (9.5 ft)(8 ft)(3 ft) = 228 ft^2

The total weight is 18.5 kilograms

Answer:

21 pounds

Step-by-step explanation:

Given that f varies inversely with l then the equation relating them is

f = \(\frac{k}{l}\) ← k is the constant of variation

To find k use the condition f = 15 when l = 7, then

15 = \(\frac{k}{7}\) ( multiply both sides by 7 )

105 = k

f = \(\frac{105}{l}\) ← equation of variation

When l = 5 , then

f = \(\frac{105}{5}\) = 21 pounds

Answer:

x=24

Step-by-step explanation:

Hi there!

We are given the following proportion:

\(\frac{2}{10}=\frac{3}{x-9}\)

And we want to solve for x.

First, let's reduce \(\frac{2}{10}\), as reducing fractions typically makes the process easier

\(\frac{2}{10}\) is the same as \(\frac{1}{5}\)

So:

\(\frac{1}{5}=\frac{3}{x-9}\)

We can't do anything to \(\frac{3}{x-9}\), but that's okay.

Now we can cross multiply, as this is a proportion

Multiply x-9 by 1 and 3 by 5

1(x-9)=3(5)

Multiply

x-9=15

Now this is an equation

Our goal is to isolate x on one side

So let's add 9 to both sides to remove it from the left side

x-9=15

 +9 +9

_________

x=24

Hope this helps!

Answer:

24

Step-by-step explanation:

Cross multiply:

2(x - 9) = 2x - 18

3(10) = 30

2x-18 = 30

   +18   +18

Answer:

C

Step-by-step explanation:

Key skills needed: Understanding inequalities, Understanding variables

1) The inequality is \(120\geq 12x + 29\)

2) This means that 12x + 29 is at most 120, not at least. At least means greater than or equal to. At most means less than or equal to.

3) 29 is the initial amount -->  So C is the answer. C says that 29 is the initial amount, and 12 coins are being added every year (k is the number of years). C  also says "AT MOST".

Therefore C is the answer

Given that,

8. The radius of a sphere, r = 115 cm

We need to find the surface area of the metal​ sphere. The formula for the surface area of a sphere is given by :

\(A=4\pi r^2\)

Put all the values,

\(A=4\times 3.14 \times (115)^2\\\\=166106\ cm^2\)

9. Thirty percent of the metal sphere will be covered in a metal that is tinted red.

So, the area of the section that is tinted red is :

\(A=30\%\ of\ 166106\\\\=\dfrac{30}{100}\times 166106\\\\=49831.8\ cm^2\)

Hence, this is the required solution.

Answer:

Perimeter of shape B = 50 cm

Step-by-step explanation:

Perimeter of shape A = 60 cm

Let the length of each square = x cm

Total length of free boundaries of shape A = 12x

Therefore, 12x = 60

x = 5 cm

Now length surfaces of shape B = 10x

Perimeter of shape B = 10x

                                    = 10(5)

                                    = 50 cm

1/10 of all take 2/5 time

10/10=10 times 1/10

so 10 times 2/5 time=20/5=4 days to finish 1 order

The values which will satisfy the inequality equation x² + 3x - 4 > 0 are when x = -6 and x = 5

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

x² + 3x - 4 > 0

On simplifying the equation , we get

Taking the common terms in the equation and factorizing , we get

x² + 4x - x - 4 > 0

x ( x + 4 ) - 1 ( x + 4 ) > 0

( x - 1 ) ( x + 4 ) > 0

So , the value of x which will satisfy the inequality equations are

( x - 1 ) > 0

Adding 1 on both sides of the equation , we get

x > 1

So , all the numbers greater than 1 would satisfy the inequality equation

And ,

x + 4 < 0

Subtracting 4 on both sides of the equation , we get

x < -4

So , all the numbers lesser than -4 would satisfy the inequality equation

Therefore , the inequality relation is given by 1 < x < -4

when x = -6

Substituting the values in the equation , we get

x² + 3x - 4 > 0

( -6 )² + 3 ( -6 ) - 4 > 0

36 - 18 - 4 > 0

14 > 0

Therefore , the inequality relation is true

when x = 5

Substituting the values in the equation , we get

x² + 3x - 4 > 0

5² + 3 ( 5 ) - 4 > 0

25 + 15 - 4 > 0

36 > 0

Therefore , the inequality relation is true

Hence , the values which satisfy the inequality equations are -6 and 5

The value of x is 9°

Step-by-step explanation:

8x-2°+47° = 12x+9°{an exterior angle formed by producing the side of triangle is equal to two non adjacent angle}

or, 8x+45° = 12x+9°

or, 8x-12x = 9°-45°

or, -4x = -36°

or, x = -36°/-4

or, x = 9°

The missing value for the probability distribution can be completed by option A.

What is probability distribution?

A probability distribution is a mathematical function that calculates the likelihood that various possible outcomes of an experiment will occur.

Main body:

We know that the sum of probability distribution is always 1.

P= P(X=1) + P(X=2) + P(X=4) + P(X=8) + P(X=16) + P(X=32) + P(X=64)

1= 0.1 + 0.05 + 0.25 + 0.25 + 0.05 + P(X=32) + P(X=64)

P(X=32) +P(X=64) = 1-0.7

                             = 0.3

This condition is satisfied by option A.

hence the answer is option A.

The capability index that is most desirable is a. 1.00.

The capability index, often represented by Cp, is a measure of the capability of a process to consistently produce output within specified limits. It compares the spread of the process output to the width of the specification limits.

A capability index of 1.00 indicates that the process spread is equal to the width of the specification limits, indicating a high level of capability. This means that the process is able to consistently produce output that meets the desired specifications without significant deviation.

On the other hand, a capability index below 1.00 indicates that the process spread is wider than the specification limits, indicating a lower level of capability. In such cases, the process may have difficulty consistently meeting the desired specifications.

1) The relationship between ∠2 and ∠6 is that they are alternate angles.

2) The relationship between ∠1 and ∠3 is that they are corresponding angles.

Corresponding angles are defined as the angles that are formed in  corresponding corners with the transversal when two parallel lines are intersected by any other line.

Alternate angles are defined as the angles that are formed by the intersection of a transversal and two parallel lines.

This alternate angle could either be interior alternate or exterior alternate.

1) Since we are told that Line 1 is parallel to Line 2, then it means that from definition of alternate angles that ∠2 and ∠6 are alternate angles.

2) Since we are told that Line 1 is parallel to Line 2, then it means that from definition of corresponding angles that ∠1 and ∠3 are corresponding angles.
