Answer:

500 phones

Step-by-step explanation:

cost of manufacturing: y = 80x + 10,000

money from phone sales: y = 100x

* note: x = #phones

solve for when they're equal;

100x = 80x + 10,000

100x - 80x = 80x - 80x + 10,000

20x = 10,000      –––––––––––> divide both sides by 20

x = 500

Answer:

the area of the disk is 50.24 inches^2

Step-by-step explanation:

The computation of the area of the disk is as follows:

As we know that

The area of the circle is

= πr^2

= 3.14 × 4^2

= 3.14 × 16

= 50.24 inches ^2

hence, the area of the disk is 50.24 inches^2

Answer:

x=97° a=97° b=97°

Step-by-step explanation:

83°+a=180° (by linear pair)

a=180°- 83°

a=97

and a=x°(by corresponding angle)

x= 97°

x=b(by vertical opposite angle)

b = 97°

Answer:

a. 18

b. 17/36

d. 157.5615

e. 19.8

Step-by-step explanation:

Hope this helped!

Answer:

a. 18 b. 15/64 c. 122 2/9 d. 157.5615 e. 19.8

Step-by-step explanation:

a.

b. multiply across, so 1 * 15 = 15, 4*16=64, 15/64 can't be reduced, so done

c. 13 3/4 * 7 8/9, you must convert to improper fractions to multiply

4*13+3 = 55 so the first part is 55/4, 7*9+8=80 so the second is 80/9

55/4 * 80/9 = (55*80) / (4*9) = 4400 / 36, both are divisible by 4 so can be reduced to 1100/9 which cannot be reduced any further, 1100 + 9 = 122 R 2 so

1100/9 = 122 2/9

d. used calculator

e. 33% of 60 = (33//100)*(60/1) = (33*60) / (100*1) = 1980 / 100 = 19.8

Step-by-step explanation:

Amount of money spend in 1 day = x

So, amount of money spend in 7 days = (7x)

⇒ Amount of money spend in 1 week = (7x)

Amount of money saved in 1 week = y

∴ Income in 1 week = (7x + y)

So, income in 3 weeks = [3 x (7x + y)]

= (21x + 3y)

Answer:

total income after 3 weeks=7×3(x+y=21x+21y

income=saving + expenses

The answer is -7s

Answer:

A. 2[tex]\frac{1}{2}[/tex]

Step-by-step explanation:

You have to replace x with one of the values in the set. You have to find the one that works.

3[tex]\frac{1}{2}[/tex]x = 8[tex]\frac{3}{4}[/tex]

8[tex]\frac{3}{4}[/tex] ÷ 3[tex]\frac{1}{2}[/tex] = x

8[tex]\frac{3}{4}[/tex] ÷ 3[tex]\frac{1}{2}[/tex] = 2[tex]\frac{1}{2}[/tex]

b) per week

c) per hour

Answer:

Both coordinates should be negative

Step-by-step explanation:

When you go to plot a point, you always start at (0,0). Since you go left 0.5 units, that would put you at -0.5, then you go down 0.25 units which would put you at (-0.5, -0.25). The result would be (-0.5, -0.25). Hope this helps! :)

Answer:

x = 130 degrees

Step-by-step explanation:

We know that the total angle equals to 180 degrees since it is a straight line

Therefore, 25 + 25 + x = 180

180 - 25 - 25 = 130

Therefore, x = 130 degrees

Plz mark brainliest :D

Step-by-step explanation:

As we know that sum of all angles on a straight line is 180°

thus,

25°+x+25° = 180°

=> x + 50° = 180

=> x = 180° - 50°

=>. x = 130°

Answer:

8 to 6

Step-by-step explanation:

The question is asking what is the ratio of "tablespoons of raspberries" TO ratio of "tablespoons of sugars".

= 8 tablespoons of raspberries TO 6 tablespoons of sugar

= 8 (tablespoons of raspberries) TO 6 (tablespoons of sugar)

= 8 TO 6

The ratio of tablespoons of raspberries to tablespoons of sugar should be considered as the 8 to 6.

Since Macy's aunt makes raspberry jam using 6 tablespoons of sugar and 8 tablespoons of raspberries.

So here the ration be like

= 8 raspberries tablespoons to 6 tablespoons of sugar

= 8 to 6

hence, the second option is correct.

Answer: 8/9

Step-by-step explanation:

The common multiple they all share is 18, so change the denominator to that for all the fractions.

2/3 = 12/18

13/18 = 13/18

7/9 = 14/18

5/6 = 15/18

The next answer would be 16/18 which is equivalent to 8/9

Answer:

12/18,13/18,14/18,15/18

the next would be 16/18=8/9
