At Sally's Diner, combo meals come with either chips or fries. Of the 115 customers on Friday, 80% ordered combo meals. Of these 3/4 had fries. How many customers on Friday had fries with their meals?

A. 69
B. 72
C. 86
D. 92

Answers

Answer:

A: 69

Step-by-step explanation:

80% of 115 customers had combos. To find out the amount that had combos, we multiply the amount of customers by percentage. 115 * 80% (0.8) is 92. 92 customers had combo meals. 3/4 of them had fries with it, and 3/4 is 75% in percent form. We multiply 92 by 75% to get the amount that had fries. 92 * 75% (0.75) is 69. There. Sally's Diner had 69 of Friday's customers order fries with their combo meals.

115 x .80% = 92

92 x .75% = 69

Answer : A. 69

The sales tax for an item was $8.80 and it cost $440 before tax.
Find the sales tax rate. Write your answer as a percentage.

Answers

Answer:

Step-by-step explanation:

In non-mathematical form, the question is asking $8.80 is what percent of $440. N will equal the percent. So, you would set up the equation like this: 20 = N · 440

You need to solve the equation.

20/440 = N · 440/440

0.045 repeating = N

Rounded, the sales tax rate would be 4.5%

The point (1, –5) is reflected across the y-axis. A coordinate plane. What are its new coordinates?
(–1, 5)
(1, –5)
(–1, –5)
(1, 5)

Answers

Answer: Choice C. (-1, -5)

Explanation:

The reflection rule we use is

[tex](x,y) \to (-x, y)[/tex]

when we want to reflect over the y axis. The x coordinate flips from positive to negative, or vice versa, while the y coordinate stays the same.

Therefore, [tex](1, -5) \to (-1, -5)[/tex]

What is the total surface area of this rectangular pyramid?
A rectangular pyramid. The rectangular base has a length of 12 feet and width of 6 feet. 2 triangular sides have a base of 12 feet and height of 8 feet. 2 triangular sides have a base of 6 feet and height of 9.5 feet.
_____________ square feet
HELP PLS!!!

Answers

Answer:

225 square feet

Step-by-step explanation:

the base of the pyramid would be 76 ft², since 12*6=72. Then you get the surface area of the sides. 2 of the sides would be 48 ft², since (12*8)/2=48. The other 2 sides would be 28.5 ft², since (6*9.5)/2-28.5. Then you just add the surface areas of all the sides; 76+48+48+28.5+28.5 to get 225.

Bob is packing a suitcase to take on an airplane. A suitcase and its contents can weigh at most 50 pounds before the airlines charge extra fees. Bob's suitcase weighs 10 pounds when it is empty, so he can put 40 pounds of clothes in the suitcase. Bob's shirts weigh 0.5 pounds each and his pants weigh 2 pounds each.

(1)Write an equation that would model how many pounds of clothing Bob can pack.

(2)Rewrite the equation to model the number of pants Bob can pack in terms of the number of shirts.

Answers

Answer:

1. 10x + 40 = 50

2. 10x + 2 + 0.5 = 40

Step-by-step explanation:

1. If bob's suitcase is 10lb. by itself then that is 10.

His limit of content and suitcase is 50lb.

His shirts weigh 0.5lb each.

His pants weigh 2lb each.

10x + 40 = 50

2. 10x + 2 + 0.5 = 40

-6 2/9 x (7 3/6) = _______________
(These are mixed fractions)
Improper form :
-56/9 x (45/6) = __________

Answers

-21 7/9 or -(14/3)^2

Step-by-step explanation:

With the mixed, start with the whole numbers

-6 * 7 = -42

Then do the fractions

[tex]-\frac{2}{9} *\frac{3}{6}[/tex]

simplify

[tex]-\frac{2}{9} *\frac{1}{2}[/tex]

[tex]\frac{2}{18}[/tex]

simplify : [tex]\frac{1}{9}[/tex]

and you end up with: [tex]-42\frac{1}{9}[/tex]

With the improper

[tex]\frac{-56}{9} *\frac{45}{6}[/tex]

Start by simplifying the fraction down

[tex]\frac{-28}{1} *\frac{5}{3}[/tex]

Multiply

[tex]-\frac{140}{3}[/tex]
