of hot chocolate y varies directly with the number of hot chocolate
ordered x. What is the cost of one hot chocolate? *
O A. $0.36
O B. $8.25
O C. $2.75
O D. $3.00

Answers

Answer 1

Answer:

C) $2.75

Step-by-step explanation:

8.25/3 = 2.75

Answer 2

Answer:

C. $2.75

Step-by-step explanation:

3 cups of chocolate and each is $8.25. To solve this, the equation would be:

$8.25/3

This is equal to $2.75, so that is the answer!

( Also, 2.75 * 3 = 8.25, so it's correct! )

1/2x +y=-4
y = 2x + 16

Answers

sub 2x+16 for y into the 1st line so
1/2x+2x+16=-4 now find x
which is x=8 not plug in -8 for x, does not matter which one
you will get y=0
answer•
x=-8
y=0
(-8,0)

Answer:

y = 0

x = -8

Step-by-step explanation:

1/2x + y = - 4

y = 2x + 16

1/2x + (2x + 16) = - 4

1/2x + 2x = - 4 - 16

5/2x = -20

2/5 x 5/2x = -20 x 2/5

x = -40/5

x = -8

y = 2x + 16

y = 2(-8) + 16

y = -16 + 16

y = 0

Check:

1/2x + y = - 4

y = 2x + 16

1/2(-8) + (0) = -4

-4 + 0 = -4

-4 = -4

y = 2x + 16

(0) = 2(-8) + 16

0 = -16 + 16

0 = 0

Anthony has 15 coins, all of which are quarters and dimes. In all, they're worth $3.60. How many of each kind of coin does Anthony have?

Answers

Answer:

1 Dime

14 Quarters

Step-by-step explanation:

d + q = 15

0.10d + 0.25q = 3.60

d = 15 - q

0.10d + 0.25q = 3.60

0.10(15 - q) + 0.25q = 3.60

1.5 - 0.10q + 0.25q = 3.60

0.15q = 3.60 - 1.5

0.15q = 2.1

0.15q/0.15 = 2.1/0.15

q = 14

d = 15 - q

d = 15 - 14

d = 1

Solve the system of equations using elimination.
3x-2y=5
x+2y=3

Answers

Answer:

x = 2

y = 1/2

Step-by-step explanation:

3x - 2y = 5

x + 2y = 3

We don't have to mutiply anything because we have values that we can eliminate.-2y and 2y can be crossed off becuase they have the same value and plus and minus cancel out. We can add instead of changing the signs.

4x = 8

x = 2

Now we know that x = 2. To find y we have to plug in x into one of the equations. I am going to use x + 2y = 3.

2 + 2y = 3

2y = 1

y = 1/2

Now we figured out y. I hope I helped!

There were 43 cars in the race. They all finished the 265 miles of the race and they each used about 1 gallon of gas to go 5 miles. About how many gallons og gas did the cars use altogether to finish the race?

Answers

Answer:

2,279 gallons of gas.

Step-by-step explanation:

Given;

total number of cars in the race, t = 43 cars

total distance traveled by each car, d = 265 miles

5 miles ---------------- 1 gallon of gas

265 miles ------------ x gallon of gas

x = 265 / 5

x = 53 gallons

Total gallons of gas used by the 43 cars in the race is given as;

Total gallons of  gas = 53 gallons x 43 cars

Total gallons of  gas = 2,279 gallons of gas.

Therefore, the toal gallons of gas the cars used altogether to finish the race is 2,279 gallons.

What is Probability?

Probability helps us to know the chances of an event occurring.

[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]

Given that Students are 37% likely to major in Performing Arts; 43% likely to choose Science and Technology; 82% likely to major in Business and Management; and 63% likely to select Humanities. Therefore,  the probability of the union of majoring in either Performing Arts or the Humanities is,

P(Humanities ∪ Arts) = P(Humanities) + P(Arts) - P(Humanities)(Arts)

                                  = 0.63 + 0.37 - (0.63 x 0.37)

                                  = 1 - 0.2331

                                  = 0.7669 ≈ 0.77

Hence, the correct option is C.
