Answer:

Coffee = 25

Hot Chocolate = 250

Step-by-step explanation:

Coffee: c

Hot Chocolate: h

0.75h + 0.50c = 200

h + c = 275

h + c = 275

h = 275 - c

0.75h + 0.50c = 200

0.75(275 - c) + 0.5c = 200

206.25 - 0.75c + 0.5c = 200

-0.25c = -6.25

-0.25c/-0.25 = -6.25/-0.25

c = 25

0.75h + 0.5(25) = 200

0.75h + 12.5 = 200

0.75h = 200 - 12.5

0.75h = 187.5

0.75h/0.75 = 187.5

h = 250

Check: c = 25; h = 250

0.75h + 0.50c = 200

h + c = 275

0.75(250) + 0.5(25) = 200

187.5 + 12.5 = 200

200 = 200

h + c = 275

250 + 25 = 275

275 = 275

A) 6

Step-by-step explanation:

The angle 12x is the same angle as the one below 108 degrees. They are supplementary angles so they add up to 180 degrees. 180-108 = 72, 12x = 72 divide each side by 12, x = 6 :)

Answer:

4th option is correct.

Answer:

1).Sugar used in 7 days = 61.25 pounds

2). Total cost of 9 cupcakes = $38.25

Step-by-step explanation:

1). Alani uses 8.75 pounds of sugar each day.

  So, sugar used in 7 days = Amount of sugar used in one day × Number of    days

= 8.75 × 7

= 61.25 pounds

2). Since, each cupcake costs $4.25

   Number of cakes ordered = 9

  Total cost of 9 cupcakes = Cost of each cupcake × Number of cupcakes

                                             =  4.25 × 9

                                             = $38.25

a) 15160 gallons

b) 3032 gallons

Step-by-step explanation:

Given that for every penny increase in the price of gasoline there is a decrease of 1516 gallons sold per week

a) when she raises the price by 10 cents per gallon

There will be a decrease of ( 1516 * 10 ) gallons sold per week i.e. = 15160 gallons

b) when she decrease the price by 2 cents per gallon

There will be an increase ( 2 * 1516 ) gallons sold per week  i.e. = 3032 gallons

Answer:

A.43.0

Step-by-step explanation:

area of rectangle= l*w=10 units *20 units= 200 units^2

area of the 2 circles:

diameter= 20/2=10 units

r=d/2= 10/2=5 units

area of a circle= 3.14*r^2

=3.14*5*5

=78.5> the 2 circles are identical then they have the same area

area of the shaded region= area of the rectangle- 2*area of one circle

= 200- (2*78.5)

=200-157

=43.0

therefore the area of the shaded region is 43.0 units^2

Step-by-step explanation:

We are informed that the expression below represents Brianna’s age in

terms of m, Molly’s age.

3m − 5.

This shows that 3m simply means that 3 times of Molly's age while the -5 represent less than 5. This will now be:

Brianna’s age is 5 less than 3 times Molly age.

Answer:

y > -1/4x + 4

Step-by-step explanation:

First find the equation of the line itself, which is y = -1/4x + 4, then determine if graph shades above the line or below the line. If it shades above which is true in this case, it will be greater than. If it shades below which does not occur in this case, it will be less than. Because the line is dashed and not solid, it will just be greater than or less than.

Therefore y = -1/4x + 4 → y > -1/4x + 4 [Shades above the line, line is dashed].

Answer:

ASA

Step-by-step explanation:

The graph that shows the solutions to the inequality is the last graph.

Here we have the inequality:

-3.55g ≤ -28.4

To solve this, we need to isolate g, we can divide both sides by -3.55

g ≤ -28.4/-3.55 = 8

g ≤ 8

Then we must have a black dot at x = 8, and we shade the region to the left of it, meaning that the correct graph is the last one.
