D. 20°

Answer:

5, 7, 9, 11

Step-by-step explanation:

w < 12

w ∈ { 5, 7, 9, 11 }

Answer: D

If there are 713 slices, and each pizza is divided into pieces, then you would divide.

713÷8=89.125. Round up and you get:

90.

Hope this helps and have a great day!!!

For this case we must indicate the number of whole pizzas needed for the company. For this we propose an equation.

Let "x" be the variable that represents the number of whole pizzas, then:

[tex]8x = 713[/tex]

We divide between 8 on both sides of the equation:

[tex]x = \frac {713} {8}\\x = 89,125[/tex]

90 pizzas are needed

Option D

Answer:

D) no solution

Step-by-step explanation:

1/ (x-2) + 1/(x+2) = 4/(x^2-4)

x cannot equal 2 or -2 since that would make our fractions equal 1/0 or be undefined

Factor the term on the right

1/ (x-2) + 1/(x+2) = 4/(x-2)(x+2)

Multiply both sides by (x-2) (x+2)

(x-2) (x+2) (1/ (x-2) + 1/(x+2)) = 4/(x-2)(x+2)*(x-2) (x+2)

Distribute

x+2 + (x-2) = 4

Combine like terms

2x = 4

Divide by 2

2x/2 = 4/2

x =2

But this is not a possible solution since that is not in the domain

[tex]S_n=\frac{13}{2}\left(12+75\right)[/tex]

[tex]S_n=\frac{13}{2}\left(87\right)[/tex]

[tex]S_n=\frac{1}{2}\left(1131\right)[/tex]

[tex]S_n=565.5[/tex]

Hence final answer is [tex]S_n=565.5[/tex].

Answer: 3,600,000 cm³

Step-by-step explanation: First you have to convert all the units into centimeters,

2 meters = 200 centimeters

1.5 meters = 150 centimeters

To find the volume of a rectangular prism you multiply all the sides.

120 * 200 * 150 = 3,600,000

The answer is 3,600,000 cubic centimeters.

The volume of a rectangular prism with the given dimensions is 3.6 cubic meters.

The dimensions of a rectangular prism are 120 centimetres(1.2 meters) by 2 meters by 1.5 meters.

The formula to find the volume of a rectangular prism is l×b×h.

Now, volume=1.2×2×1.5=3.6 cubic meters.

Therefore, the volume of a rectangular prism is 3.6 cubic meters.

The would both be correct in it's own way depending on how the teacher is teaching.

Both Joel and Sara are correct. Their expressions represent the combined earnings accurately, considering hourly wage and bonus.

To determine who is correct, let's first break down the earnings for each person:

1. Joel:

  - Hourly wage: $9.75

  - Bonus: $18

  Joel's total earnings can be calculated using the formula provided: [tex]\(9.75j + 18\)[/tex], where [tex]\(j\)[/tex] represents the number of hours Joel worked.

2. Sara:

  - Hourly wage: $9.75

  Sara's total earnings can be calculated using the formula provided: [tex]\(9.75(j + S)\)[/tex], where [tex]\(S\)[/tex] represents the number of hours Sara worked.

Now, let's expand both expressions and see which one correctly represents the combined earnings of Joel and Sara.

Joel's expression: [tex]\(9.75j + 18 + 9.75S\)[/tex]

Sara's expression: [tex]\(9.75j + 9.75S + 18\)[/tex]

Comparing the two expressions, we see that both expressions have the same terms: [tex]\(9.75j\)[/tex], [tex]\(9.75S\)[/tex], and [tex]\(18\)[/tex]. The order of terms is different, but mathematically it doesn't matter since addition is commutative.

So, both Joel and Sara are correct. They just wrote their expressions in a different order, but the mathematical result is the same. They both correctly accounted for their hourly wage and the bonus.

Option 3

Answer:

option B

Step-by-step explanation:

Given in the question an equation y = (x+3)² + (x+4)²

Step 1

Expand this equation

y = (x+3)² + (x+4)²

y = (x²+9+6x) + (x²+16+8x)

y = 2x² + 14x + 25

Answer:

5/10

Step-by-step explanation:

The cube root of 125 is 5 and the cube root of 1000 is 10.

Final answer:

The cube root of 125/1000 simplifies to 5/10 or 0.5. This is determined by taking the cube root of both the numerator and the denominator separately, or by understanding properties of exponents and simplification of fractions.

Explanation:

To evaluate the cube root of 125/1000, we can simplify this expression by looking for cube roots of the numerator and the denominator separately. The cube root of 125 is 5 because 5³ equals 125. Similarly, the cube root of 1000 is 10 because 10³ equals 1000. Therefore, the cube root of 125/1000 is 5/10, which simplifies to 1/2 or 0.5.

Another way to approach this is by using the fact that 125 is a “125–like” number, which helps us recognize that 125 is one eighth of 1000, as 1000 multiplied by the reciprocal of 8 (which is 1/8) is 125. This intuitive understanding confirms that the cube root of 125/1000 simplifies to a small number like 0.5.

Total surface area of cone = πrl + πr^2. Since the radius is 12 in. and the slant height is 15 in, substitute 12 for r and 15 for l.

A = π(12)(15) + π(12)^2

4. [tex]6x-7+7=12+7[/tex] - Simplification

7. [tex]x=\frac{19}{6}[/tex]

To solve the problem, we need to start with the result of the second step:

[tex]6x-7=12[/tex]

So,

For the step 3:

Then, for the 3rd step, we have to apply the addition property of equality.

The addition property of equality states that if we add a term to one side of the equality, we need to add it to the other side of the equality, in order to not alterate the equality.

Then, applying the property, we have:

[tex]6x-7=12[/tex]

Adding 7 to both sides, we have:

[tex]6x-7+7=12+7[/tex]

For the step 4:

Now, for the 4th step, we have to simplify the expression:

[tex]6x-7+7=12+7[/tex]

Then, simplifying, we have:

[tex]6x=19[/tex]

For the step 7:

Step-by-step explanation:

So, you want to calculate the interest on $300 at 5% interest per year after 7 years.

The formula we'll use for this problem is:

Where:

To find the simple interest, we multiply 300 x 0.05 x 7 to get that:

                                         The interest is: $105.00

Answer:

The correct answer is last option

$105.00

Step-by-step explanation:

Points to remember

Simple interest

I = PNR/100

Where P - Principle amount

N - Number of years and

R - Rate of interest

To find the simple interest

Here P = $300, R = 5% and N = 7 years

I = PNR/100

 = (300 * 5 * 7)/100

 = 3 * 5 * 7

 = 105

Therefore simple interest after 7 years = $105

The correct answer is last option

Answer:

57°

Step-by-step explanation:

ALL angles in a triangle add up to 180°

SO, if we know the sum of two angles which is 123° (why: 33+90=123), all we have to do is subtract this number from 180 to get the measure of the 3rd angle. Which in this case is 57°

The measure of angle B will be 57° for the given triangle.

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.

There are many types of triangles such that right angle triangle, equilateral triangle, and much more.

The sum of all three interior angles of any triangle is 180°.

So,

A + B + C = 180°

Given,

A = 33°  and C = 90°

33°  + B + 90°  = 180°

B = 180 - (90 + 33)

B = 180°  - 123°  

B = 57°

Hence, The measure of angle B will be 57° for the given triangle.

Step-by-step explanation:

by multiplying the first term by -3 then -6X-3y=-3

                                                            and  2X+3y=11

then by adding = -4X=8

then X=8/-4=-2

The value for x in the given system of equations is found by using the method of elimination, resulting in x = -2. The value of y was found first, namely y = 5, and was then substituted into the first equation to find x.

The system of equations given is:

To find the value of x, we can use the method of elimination or substitution. Let’s use elimination. First, subtract the first equation from the second.

That gives us: 2x + 3y - (2x + y) = 11 - 1

Which simplifies to: 2y = 10

Then divide both sides by 2: y = 5

Now substitute y = 5 into the first equation: 2x + 5 = 1, which simplifies to 2x = -4, and lastly x = -2.

So the solution for x in the system is x = -2 (option a.).
