6. In a jar of 650 marbles, 20% of the marbles are red.
How many marbles are not red

Answers

Answer:

Step-by-step explanation:

20% of 650

1/5 of 650

130=red

520= not red

Answer:

520

Step-by-step explanation:

20% are red which means 130 are red

650-130= 520

or you could look at it this way

if 20% is red that means 80% is not red

80% of 650 is 520

A store is offering a 20% discount on all items. Is there a proportional relationship between the original price of an item and its price after the discount?

Answers

Answer:

A store is offering a 14% discount on all items. Write an equation relating the sale price S for an item to its list price L.

Step-by-step explanation:

Yes there is  a proportional relationship between the original price of an item and its price after the discount assuming a store is offering a 20% discount on all items

Let p represent  original price of the commodity

Let the current price be:

Current price (p1)=Original price-Discount amount

Current price (p1)=P-Px20%)

Current price (p1)=p(1-20%)

Current price (p1)=0.8P

Hence:

P1=0.8P

P1÷P=0.8

Based on the above there is  a proportional relationship between the original price of an item and its price after the discount.

Inconclusion Yes there is  a proportional relationship between the original price of an item and its price after the discount assuming a store is offering a 20% discount on all items.

What is the equation, in slope-intercept form, of the line with a slope of -1/3 and y-intercept of (0, 9)? Choices in picture below

Answers

Step-by-step explanation:

The formula is y=mx+b, with m representing the slope, x representing the x coordinate, and b representing the y-intercept. Since -⅓ is the slope, that means that the equation starts off as y=-⅓. We know that the y-intercept is where the line meets the y-axis, so the y-intercept is 9. Since 9 (the y-intercept) is being added, that means the equation is y=-⅓+9.

Answer:

y=-⅓+9

The equations 3x-2y=-14 and 3x+y=-11 are plotted on the same set of axes. what are the coordinates of a point that's common to both equations? how do you know?​

Answers

Answer:

14

Step-by-step explanation:

Answer:

(-4, 1)

Step-by-step explanation:

Solve it as a system of equations:

[tex]3x-2y=-14\\3x+y=-11[/tex]

subtract the two equations

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

divide both sides by -3

[tex]y=1[/tex]

Plug this into the equation 3x + y = -11 to solve for x

[tex]3x + 1 = -11\\[/tex]

subtract 1 from both sides

[tex]3x = -12[/tex]

divide both sides by 3

[tex]x = -4[/tex]

So the answer is (-4, 1)

How many kilograms of rice will each person get if 6 people share 1-2 of a kilogram of rice equally?

So if a man has 1/2 kg of rice then he shares to 6 people equally.

So all you have to do is just take the total amount of rice then divide it to 6 people.

So 1/2 ÷ 6 equals to 1/12 in fraction form.
