Answer:

15 servings

Step-by-step explanation:

total amount of lemonade = 19.64 cups

lemonade per serving = 1.25 cups

total servings = 19.64 cups / 1 .25 cups = 15.712 servings

since you cannot sell a partially full serving, Jessica and Jonathan will only be able to sell 15 servings

in order for them to sell 16 full servings, they need to prepare 20 cups of lemonade (= 20 / 1.25 = 16)

Step-by-step explanation:

The possible values of x are positive integers that are less than 14

The perimeter of a figure is the sum of all its sides.

A triangle has 3 sides. The length of the 2 sides are given. The third side is x . Therefore,

perimeter  = 7 + 7 + x

perimeter < 28 feet

Therefore,

7 + 7 + x < 28

14 + x < 28

subtract 14 from both sides

14 - 14 + x < 28 - 14

x < 14

Therefore, the possible value of x are positive integers that are less than 14.

Step-by-step explanation:

Answer:

Each glass of milk is 9 carbs.

Each snack bar is 19.7 carbs.

Step-by-step explanation:

1. I know that 2 glasses of milk with 3 snack bars is 78 carbs.

The next part of the sentence has two times the amount of milk with the same amount of snack bars for 96 carbs.

Now, I will find the difference in the amount of carbs.

96 - 78 = 18 carbs.

So two glasses of milk = 18 carbs.

18 ÷ 2 = 9 carbs

So, each glass of milk is 9 carbs.

2. Since we know this, we can subtract the amount of carbs from the glasses of milk from the total amount of carbs.

78 - 19 = 59

In the first scenario, there are 59 carbs per 3 snack bars.

To find the amount of each snack bar, divide 59 by 3.

59 ÷ 3 = 19.7 when rounded to the nearest tenth.

Therefore, each snack bar is 19.7 carbs.

Answer:

glass of milk = 9 carbohydrates

snack bars = 20 carbohydrates

Step-by-step explanation:

Let s be snack bars and g be the glasses of milk.

3s + 2g = 78

3s + 4g = 96

-1(3s + 2g) = -1(78)

- 3s - 2g = - 78

- 3s - 2g = - 78

3s + 4g = 96

2g = 18

g = 18/2

g = 9

3s + 2g = 78

3s + 2(9) = 78

3s + 18 = 78

3s = 78 - 18

3s = 60

3s/3 = 60/3

s = 20

Check: g = 9; s = 20

3s + 2g = 78

3s + 4g = 96

3(20) + 2(9) = 78

60 + 18 = 78

78 = 78

3(20) + 4(9) = 96

60 + 36 = 96

96 = 96

So, the solution is g = 9; s = 20

Answer:

the answer is 1/8

Step-by-step explanation:

there are 8 options and the percentage is 1

Answer:

Step-by-step explanation:

1290

Based on the amount invested, the rate, and the period of compounding, after 11 years, the account would be $1,290.

As the rate is compounded daily, the rate and the period need to be converted to daily figures:

Rate = 5.8% / 365 days = 5.8/365 %

Period = 11 x 365 = 4,015 days

The amount in 11 years is:

= Amount x ( 1 + rate) ^ period

= 680 x (1 + 5.8/365%) ⁴⁰¹⁵

= $1,286.965

= $1,290

In conclusion, the account would have $1,290.

Answer:-49

Step-by-step explanation:(10,1)= (x,y) so we can see that x=10 and y=1. Now you put them in the equation 1=b+5*10. Then you get 1=b+50 and you put 50 to the left side and it becomes negative. 1-50=b . Therefore b=-49

Answer:

Step-by-step explanation:

y = 5x + b ⇒ b = y - 5x

(10, 1)

b = 1 - 5(10) = 1 - 50 = - 49

b = - 49

The plotted dots connect to create a parallelogram with two sets of parallel lines in the second quadrant

Step-by-step explanation:

This might be a little tricky to explain but I will try my best.

A parallelogram is a four-sided plane rectilinear figure with opposite sides parallel.

The first pair of numbers is in the second quadrant the second set is also in the second quadrant a little bit up and to the right. The third set in the line a little up, the last set is again in the second quadrant and a little further down and near the middle.

Sorry if the answer isn't what you had hoped for, feel free to ask questions about it and I'll explain the best I can.
