1. A local pizzeria sold 75 pizzas yesterday.

(A) The owner offers the employees a bonus if the number of pizzas sold increases by 20% today.

How many pizzas must the pizzeria sell for employees to receive the bonus? Explain your reasoning. Show your work!

(B) Suppose the actual number of pizzas sold today was 66. Describe the number of pizzas sold as a percent increase or decrease. Show your work!

Answers

Answer:

(A) The pizzeria needs to sell 90 pizzas to receive the bonus.

(B) It would be a 12% decrease then the original amount of pizzas sold which is 75.

Step-by-step explanation:

(A)- You convert 20% into a decimal which is 0.20 then multiply it to 75 to find out how many more pizzas need to be sold for them to receive the bonus. In this case it was 15. Then you add it to the 75 and you get 90. So the pizzeria needs to sell 90 pizzas for them to receive their bonus.

(B)- First you see if it was an increase or decrease. In this case it was a decrease because it dropped from 75 to 66. Now you calculate by how much it had dropped. Here it dropped by t9. Now to find the percent on how much it dropped you divide 9 by 75 and you get 0.12. Then you multiply by 100 to get your percentage with is 12%. So the number of pizzas sold today would show as a 12% decrease.

If you can make my answer the brainliest that would be much appreciated. Thanks!

Find the perimeter and area of a circle with diameter 14 m​

Answers

Answer:

perimeter = 43.96 m

area = 153,86 m2

Step-by-step explanation:

d = 14 m

r = 7 m

perimeter = 2πR = 43.96 m

area = π[tex]R^{2}[/tex] = 153,86 m2

Find radius (half diameter) then area is Pi x r squared which is Pi x49 for area and permitter is 2 x Pi x r which in this case is pi x 14

Answers

Answer:

x=[tex]-\frac{113}{3}[/tex]

Step-by-step explanation:

First, we need to solve the angle inside the triangle. That would be 55+40+angle measure=180

angle measure=85°

Now that we know that, we can solve for x by setting 85-3x-18 equal to 180° because these two values form a linear pair which is 180°.

Let's use some simple algebra to solve for x:

85-3x-18=180

67-3x=180

-3x=113

x=[tex]-\frac{113}{3}[/tex] or about -37.67

Hope this helps!! :)

nter the equation of the line in slope-intercept form.

Slope is 6, and (1, 3)

Answers

Answer:

The equation in the slope-intercept form will be:

[tex]y=6x-3[/tex]

Step-by-step explanation:

Given

slope = m = 6point = (1, 3)

As we know that the equation of a line in point-slope form is

[tex]y-y_1=m\left(x-x_1\right)[/tex]

substituting the values m = 6 and point = (1, 3)

[tex]y-3=6\left(x-1\right)[/tex]

Writing the equation in slope-intercept form

[tex]y=mx+b[/tex]

where m is the slope, and b is the y-intercept

so the equation of the line in slope-intercept form becomes

[tex]y-3=6\left(x-1\right)[/tex]

add 3 to both sides

[tex]y-3+3=6\left(x-1\right)+3[/tex]

[tex]y=6x-3[/tex]

Therefore, the equation in the slope-intercept form will be:

[tex]y=6x-3[/tex]

What is an Inscribed Angle?

An inscribed angle is the angle that an arc at any point on the circle subtends.

Given information:

A circle is centered at 'A'.

m∠RBD = 34°.

Arc RD is given.

To find the angle measure m∠DAR:

m∠DAR is inscribed in a circle.

m∠DAR can be described as m∠DAR  = m∠RBD

m∠DAR = 2 x 34°.

m∠DAR = 68°.

Therefore, m∠DAR = 68°.

What percent of 85 is 51 ?​

Answers

Answer:

60%

Step-by-step explanation:

51/85×100×1/00

=3/5×100×1/100

=60×1/100

=60%

60 percent of 85 is equal to 51.

As per the given data:

We have to find what percent of 85 is 51.

In mathematics, a value or ratio that can be expressed as a fraction of 100 is known as a percentage. To determine a percentage of a number, divide it by its value, then multiply the result by 100.

By using the above definition, we can find percentage.

Let's assume x percent of 85 is equal to 51.

= x% of 85 = 51

= (x/100) × 85 = 51

= (x/100) = 51/85

= (x/100) = 0.6

= x = 0.6 × 100 = 60

Hence, 60 percent of 85 is equal to 51.
