The restaurant sold coffee and tea during the breakfast shift. The number of cups of tea they sold was 6 more than 1/3 of the number of cups of coffee sold. If the total cups of coffee and tea sold was 70, how many cups of each were sold?

Answers

Answer:

cups of tea = 22

cups of coffee = 48

Step-by-step explanation:

c = coffee

t (tea) = 6 + 1/3c

t + c = 70

c + 6 + 1/3c = 70

4/3c + 6 = 70

4/3c = 64

4c = 192

c = 48

t = 70 - 48 = 22

What is the value of y in the solution to the following system of equations?
5x - 3y = -11
2x - 5y = -14 (1 point)
O-1
OO
1
2

Answers

Answer:

Option D is the correct answer.

Step-by-step explanation:

The equations are:

5x - 3y = -11 Eqn 1

2x - 6y = -14 Eqn 2

We have to find the value of y so we will eliminate x.

Multiplying Eqn 1 by 2

2(5x-3y=-11)

10x-6y=-22 Eqn 3

Multiplying Eqn 2 by 5

5(2x-6y=-14)

10x-30y=-70 Eqn 4

Subtracting Eqn 4 from Eqn 3

(10x-6y)-(10x-30y)= -22-(-70)

10x-6y-10x+30y = -22 + 70

24y = 48

[tex]\frac{24y}{24}=\frac{48}{24}\\y=2[/tex]

Therefore,

Option D is the correct answer.

Judy is selling small candles at the fair for $4 each and large candles for $6 each. She collected $144 selling a total of 28 candles. How many of each candle did she sell? Use x for the small candles and y for the large candles.

small candle x= blank candles
large candle y = blank candles

Answers

Answer:

Number of small candles = 12

Number of large candles = 16

Step-by-step explanation:

Total candles = 28

x + y = 28 ---------------(I)

Cost of 'x' small candles = 4 *x = 4x

Cost of 'y' large candles = 6 *y = 6y

Total amount = $144

4x + 6y = 144 -------------(II)

Multiply equation (I) by (-4) and then add the equation. So, x will be eliminated and we can find the value of 'y'

(I) * (-4) -4x - 4y = -112

(II) 4x + 6y = 144 {Now, add}

2y = 32

y = 32/2

y = 16

Plug in y = 16 in equation (I)

x + 16 = 28

x = 28 - 16

x = 12

Answer:

small candles-x

large -y

144-4x=6y

28-x=y

28-y=x

(28-x)6+4x=144

168-6x+4x=114

-2x=-54

2x=54

x=27

27 small and 1 large

The area of a rectangular dining room is 16 square meters. The perimeter is 16 meters. What are the dimensions of the dining room?

Answers

Answer:

Step-by-step explanation:

The area is 16, and you know that it's 2 sides u need to multiply

The perimeter is 16, and you know that you need to add up all the sides

So....

A = b * h

A = 4 * 4

A = 16 CORRECT

And....

P = S + S + S + S ( s = sides)

P = 4 + 4 + 4 + 4

P = 16 CORRECT

The amount of time it takes Isabella to wait for the bus is continuous and uniformly distributed between 4 minutes and 18 minutes. What is the probability that it takes Isabella more than 7 minutes to wait for the bus

Answers

Answer:

0.25 or 25% probability

Step-by-step explanation:

The lower limit in this question = a

The upper limit = b

P(X<=x) = x-a/b-a

a = 4

b = 8

The question says it is uniformly distributed between 4 minutes and 8 minutes

Probability that it takes her more than 7 minutes to wait for the bus

P(X<=7) + P(X>7)= 1

We are to get P(X>7)

= 1 - (7-4/8-4)

= 1-3/4

= 1-0.75

= 0.25

= 25% probability it takes her more than 7 minutes to wait
