A sample of students is taken from the school’s A honor roll. The school estimates that there are actually 360 students on the A honor roll. Using this sample, how many students on the A honor roll are 8th graders?

6thgraders=15
7thgraders=11
8thgraders=14

Answer:

Answer:

x = 6

Step-by-step explanation:

(8x - 4)° + (3x + 17)° = (17x - 23)° => exterior angle theorem

Solve for x

8x - 4 + 3x + 17 = 17x - 23

Add like terms

11x + 13 = 17x - 23

11x - 17x = -13 - 23

-6x = -36

Divide both sides by -6

x = 6

Answer:x= -9

Step-by-step explanation: You would dive both sides by 8 and -72 divided by 8 is -9

Answer:-9

Step-by-step explanation:

The answer is -9 because we are solving to get x by itself. Since 8 is being multiplied by x the opposite of multiplication is division. Divide both sides by 8 to get x by itself. -72 divided by 8 is -9 because a negative divided or multiplied by a positive is a negative. To check your work you can do 8 times -9 which equals -72.

Answer:

There are 9 000 000 = 9 million reptiles in the US.

Step-by-step explanation:

Percentages and ratio:

The double of a measure, for example, is 200% of the measure.

So 1000% of a measure is 10 times the measure.

There are 90 million pet dogs in the US. The number of dogs is 1000% the number of reptiles.

The number of pet dogs is 10 times the number of reptiles, which means that:

[tex]10x = 90 000 000[/tex]

[tex]x = \frac{90 000 000}{10}[/tex]

[tex]x = 9 000 000[/tex]

There are 9 000 000 = 9 million reptiles in the US.

Step-by-step explanation:

Add all the beads together to get your total amount of beads (This will be your denominator)

1+2+2+1=6 beads in total

You only want to focus on the amount of green beads. (Which is 2 and that will be you numerator)

[tex]\frac{Numerator}{Demonator}=\frac{green beads}{Total amount of beads}[/tex]

Equation to represent the number of seventh-grade students who are not in advanced math is A =250 - (250 x 0.32)

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given that  Mountain Park Middle School, there are 250 seventh-grade students.

Currently, 32% of those students are in advanced math, then;

Therefore, the number of seventh-grade students who are not in advanced math.

100%-32% = 68%

68% of 250

Equation would be;

A =250 - (250 x 0.32)

A 10 ounce container of chocolate chips can be used to make 4 desserts.

Each desert has the same number of chocolate chips

Let number of chocolate chips in each dessert = x ounce

Therefore, chocolate chips in 4 deserts = 4x and total chocolate chips is = 10 ounce.

So equation will be 4x = 10

Answer:

a = 6.65

Area = 15.84

Step-by-step explanation:

By cosine rule in the given triangle,

BC² = AC² + AB² - 2(AC)(AB)cos(C)

a² = 5² + 9²- 2(5)(7)cos(28°)

a² = 25 + 81 - 61.81

a = [tex]\sqrt{44.19}[/tex]

a = 6.65

Area of a triangle with given three sides = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]

Here, s = Average of lengths of all sides

a, b and c are the measures of the respective sides of the triangle.

s = [tex]\frac{6.65+7+5}{2}[/tex]

s = 9.325

a = 6.65, b = 5 and c = 7

Now substitute these values in the formula to get the area,

Area = [tex]\sqrt{9.325(9.325-6.65)(9.325-5)(9.325-7)}[/tex]

        = [tex]\sqrt{9.325\times 2.675\times 4.325\times 2.325}[/tex]

        = [tex]\sqrt{250.8313}[/tex]

        = 15.838

        = 15.84

The solution is, 600g of pasta cost £ 0.9.

Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.

here, we have,

given that,

Pasta costs £1.50 per kg.

now we have to find,

How much does 600g of pasta cost

we know,

1 kg = 1000 grm.

so, we get,

1000 g Pasta costs £1.50

so, 1 g  Pasta costs £1.50/1000

so, 600 g  Pasta costs £1.50/1000 * 600

                                     = £ 0.9

Hence, The solution is, 600g of pasta cost £ 0.9.

[tex]9\sqrt{3}[/tex]

Step-by-step explanation:

The right triangle on the right is a special right triangle: a 30-60-90 triangle

30-60-90 corresponds with the angle measures on the triangle

the sides on a 30-60-90 relate to the angle opposite of it

30 ⇒x       60 ⇒ x[tex]\sqrt{3}[/tex]      90 ⇒ 2x

27 is opposite to the 60° angle

[tex]\frac{x\sqrt{3}} {\sqrt{3}} =x[/tex]   [tex]\frac{27}{\sqrt{3}}[/tex]  simplify [tex]\frac{27}{\sqrt{3} }[/tex] × [tex]\frac{\sqrt{3} }{\sqrt{3} }[/tex]     [tex]\frac{27\sqrt{3} }{3}[/tex] = [tex]9\sqrt{3}[/tex]

The required value of altitude y is 9 units which is determined by the geometric theorem.

A right triangle is defined as a triangle in which one angle is a right angle or two sides are perpendicular.

As we know that the geometric theorem states that h = √(ab),

where h is the altitude of a right triangle, a and b are the segments formed when the altitude divides the hypotenuse of a right triangle.

We have to determine the value of altitude y

As per the given figure, a = 3, and b = 27

Substitute the values  in the formula, and we get

y = √(3 × 27)

y = √81

y = 9

Therefore, the measure of y = 9.

Answer: A. That order is taken into account​ (consider rearrangements of the same items to be different​ sequences).

Step-by-step explanation:

The combination is usually given by the formula below:

C n,x = n! / x! (n-x)!

We should note that the requirements for a combination rule include:

• That r of the n items are selected​ (without replacement).

• That there be n different items available.

• That order is not taken into account​ (consider rearrangements of the same items to be the​ same).

Therefore, the option that is not a requirement of the Combinations​ Rule, ​, for the items that are all​ different will then be option A"That order is taken into account​ (consider rearrangements of the same items to be different​ sequences).

The volume of the rectangular prism is 60 cubic units

What is the Volume of a Rectangle?

The volume of the rectangle is given by the product of the length of the rectangle and the width of the rectangle and the height of the rectangle

Volume of Rectangle = Length x Width x Height

Volume of Rectangle = Area of Rectangle x Height

Given data ,

Let the volume of the rectangular prism be represented as V

Now , the equation will be

The length of the rectangular prism = 3 units

The width of the rectangular prism = 4 units

The height of the rectangular prism = 5 units

Now , the volume is calculated by

Volume of Rectangle = Length x Width x Height

Substituting the values in the equation , we get

Volume of Rectangle V = 3 x 4 x 5

On simplifying the equation , we get

Volume of Rectangle V = 60 cubic units

Therefore , the value of V is 60 cubic units

Hence , the volume of the rectangular prism is 60 cubic units
