= 7 + 9 ÷3 + 8

= 7 + 3 + 8

= 18

Hope it will help :)

Answer 2

Answer:

d. 18

Step-by-step explanation:

We are given an expression and are asked to solve, when solving, we need to follow the PEMDAS rule. Commonly used when so many factors and signs are at hand.

PEMDAS -

Parenthesis

Exponents

Multiply

Divide

Addition

Subtraction

This rule is showing what to do first when you have long expressions like these, do as followed and solve the parenthesis first :

7 + (16 - 7) / 3 + 8

7 + 9 / 3 + 8

Now divide :

7 + 9 / 3 + 8

7 + 3 + 8

Now that we only have to add, add all numbers together :

7 + 3 + 8

18

1 pizza costs $0.50 to make. They sell it for $12. Find the percent markup.

Answers

Answer:

ok let me try this again

To explain a markup, let's use an example: Let's say you purchase a box of paper that costs one dollar. You aim for a profit of 50%. By multiplying the cost by 50%, you get $0.50. This is your markup price. Add that to the price that you paid to purchase the box of paper, and now the total is $1.50. This is the selling price of the box of paper. Therefore, your markup percentage is 50%.

Find the approximate radius a circle if its circumference is 37.68 inches. Use (pie symbol)= 3.14.

Answers

Answer:

radius = 6 inches

Step-by-step explanation:

37.68/3.14 = 12 = diameter

radius = 12/2 = 6 inches

Circumference of a circle:
C = 2 pi r
r = C / 2 pi
r = 37.68 / (2 * 314)
r = 6

Area of a circle:
A = pi r^2
A = 3.14 * 6^2
A = 113.04

Answer:
The area of the circle is 113.04 square units

15 POINTS- ITS DUE TONIGHT

Answers

ok this isn’t my answer i found it on quora but it answers ur question u have

We can write a system to solve this problem

Let x= the radius of Circle A

Let y=the diameter of Circle B

x=2y-3

2x+y=49

since we are trying to find the area and the circumference of circle A, we only have to find what x is

x=2y-3 → y=1/2x+3/2

next, we plug in 1/2x+3/2 for y:

2x+1/2x+3/2=49

we can then multiply all the numbers by 2 to get rid of the fractions:

4x+x+3=98

5x+3=98

5x=95

x=19

Circle A radius=19ft

Finally, we solve for the area and circumference:

Area:

A=pi*r^2

A=3.14*19^2

A=1133.54 feet^2

Circumference:

C=2*pi*r

C=2*3.14*19

C=119.32 feet

Susie tries to read 50 pages of her book every day.
One week (7 days) she only managed to read 280 pages.

Answers

Answer: 25%

Step-by-step explanation:

Approximate value = 350

Exact value = 280

The percentage error will be calculated by using the formula:

= (Approximate value - Exact value). Exact value × 100

= (350 - 280) / 280 × 100

= 70/280 × 100.

= 1/4 × 100

= 25%

a baker makes 130 loaves so that there are 6 times as many white loaves as granary loaves. half as many brown loaves as white loaves how many of each type does he make

Answers

Answer:

Answer: 78 whites, 13 granary, 39 brown.

Step-by-step explanation:

For each 6 whites, there is 1 granary, and 3 brown.  That adds up 10 loaves, so just multiply all those numbers by 13.

The Number of white, brown and granary bread loaves are ; 78, 39 and 13 respectively.

Total loaves of bread = 130

Let :

Number of granary loaves = x

Therefore,

Number of white loaves = 6x Number of brown loaves = (1/2 × 6x) = 3x

This means that :

Number of white + brown + granary loaves = 130

(6x + 3x + x) = 130

10x = 130

x = 130÷ 10

x = 13 loaves

Therefore,

Number of granary loaves = 13 Number of brown loaves = 3(13) = 39Number of white loaves = 6(13) = 78
