Emma was about to finish grocery shopping when she noticed that cans of soup were on sale. Her total bill for groceries would be $89.61 if she purchased two cans of soup and $94.98 if she bought five cans. Which equation could be used to describe Emma's grocery bill, B, in dollars as a function of the number of cans, C, purchased?

B(C)=2.69C+84.23

B(C)=1.99C+85.63

B(C)=1.79C+86.03

B(C)=1.07C+87.47

Answers

Answer 1

Answer:

3rd option: B(C)= 1.79C +86.03

Step-by-step explanation:

Total bill

= cost of cans(number of cans) +cost of other groceries

Let the cost of other groceries be G, and the cost of cans be X.

Given that number of cans= C,

Total bill= XC +G

If 2 cans were purchased,

2X+G= 89.61 -----(1)

If 5 cans were purchased,

5X +G= 94.98 -----(2)

(2) -(1):

(5X +G) -(2X +G)= 94.98 -89.61

5X +G -2x -G= 5.37

3X= 5.37

X= 5.37 ÷3 (÷3 on both sides)

X= 1.79

Subst. X= 1.79 into (1):

2(1.79) +G= 89.61

3.58 +G= 89.61

G= 89.61 -3.58 (-3.58 on both sides)

G= 86.03 (simplify)

Total bill

= XC +G

= 1.79C +86.03

Thus, the function is B(C)= 1.79C +86.03.

Answer 2

Answer:

the answer is (C)=1.79C+86.03

Answer:

57 degrees

Step-by-step explanation

Answer:

x = 57

Step-by-step explanation:

So we know all triangles add up to 180 degrees. And that supplementary angles add up to 180 degrees.

So, we can do that missing angle + 138 = 180

180 - 138 = 42

180 - 42 - 81 = x = 57

Answers

Answer:

Step-by-step explanation:

you can make it like this

(1/4)^ x=1/16

so x=2

x = 2
This is because when you have a negative exponent like -x to rearrange it to a fraction and change the negative to a positive.
So 4^x would be the denominator and 1 would be the numerator.
So 1 / 4^x = 1 / 16
To achieve 16 from 4 you square it, therefore x = 2

2. You buy a pair of pants. The original cost of the pants is $30.00. The pants are on
sale for 20% off. Show your work or explain your mental math for each part! Pls explain!

Answers

20/100=0.2
0.2x30.00=6
30-6=24

You need to convert the 20 into a decimal so you divide it by 100 and you will have to multiply the result by the price of the pants (30.00) and it will give you what will be discounted. and he only challenges the result (6) by the price of the pants.
So the answers is 24

Answer: 24

Step-by-step explanation:

30 divided by 10 to get 10 percent which is 3, multiply that by 2 to get 20 percent which is 6, 30 (100 percent) minus 6 (20 percent) equals 24

The length of a rectangle is one inch less than five times its width. If the perimeter of the rectangle is 46 inches, find its dimensions. Write your answer as two numbers separated by a comma

Answers

Answer:

19,4 or 4,19

Step-by-step explanation:

Let the width of the rectangle be 'w' in

According to the question length of the rectangle (l) is one inch less than five times it's width;

[tex] \longrightarrow [/tex] l = (5w - 1) in

Perimeter of rectangle = 46 inches

Formula of perimeter of rectangle = 2(Length + Width)

So,

[tex]\rm \implies 2(Length + Width) = 46 \\ \\ \rm \implies 2(5w - 1 + w) = 46 \\ \\ \rm \implies 2(6w - 1) = 46 \\ \\ \rm \implies 6w - 1 = \dfrac{46}{2} \rm \implies 6w - 1 = 23 \\ \\ \rm \implies 6w = 23 + 1 \\ \\ \rm \implies 6w = 24 \\ \\ \rm \implies w = \dfrac{24}{6} \\ \\ \rm \implies w = 4 \: in[/tex]

[tex] \therefore [/tex] Width of the rectangle (w) = 4 in

Length of rectangle (l) = 5 × 4 - 1 = 19 in

The scale use for a model of kitchen is 1/4 in = 1/2 ft In the model, the kitchen measures 2 1/2 by 2 3 in. What are actual dimensions of the kitchen

Answers

Answer:

5feet by 4/3feet

Step-by-step explanation:

The scale use for a model of kitchen is 1/4 in = 1/2 ft In the model, the kitchen measures 2 1/2 by 2 /3 in. What are actual dimensions of the kitchen.

From the question, we were given the conversation rate of 1/4 in = 1/2 ft In the model,

To get actual dimensions of the kitchen if the kitchen measures 2 1/2 by 2 3 in. Then

✓Let us convert 2 1/2in to feet first= 5/2in as improper fraction.

If 1/4 in = 1/2 ft

5/2in = x ft

Then cross multiply, we have

(5/2×1/2)= 1/4 × X

5/4 = 1/4X

Make X subject of the formula

X= (5/4)/(1/4)

X=5ft.

✓Let us convert 2/3in to feet

If 1/4 in = 1/2 ft

2/3in = x ft

Then cross multiply, we have

1/4×X=2/3×1/2

X=(2/3×1/2)/(1/4)

X=4/3feet

Therefore, the actual dimensions of the kitchen is 5feet by 4/3feet

A coach travels to the beach which is 576 KM away in 6 hours. If he is only allowed to travel at a maximum speed of 90 kph, did the coach break the speed limit? What was his average speed?

Answers

Answer:

Yes

Step-by-step explanation:

576Km:6Hrs

576 divided by 6=96 km

6 divided by 6=1

96km:1hr

96 was the coaches speed limit

km=Kilometers

Hrs=Hours

96>90

yes , the coach break the speed limit and the average speed is 96 km ph

What is Speed?

Speed is the time rate at which an object is moving along a path

Given,

A coach travels to the beach which is 576 KM away in 6 hours.

The maximum speed he can travel is speed of 90 kph

We need to check whether the coach breaks the speed limit or not.

Yes he has to break the speed limit because in 6 hours with 90kph he can travel only 540 km. He still needs to travel 36 km.

and the average speed he has to maintain is 576/6

96kmph

Hence, yes the coach break the speed limit and the average speed is 96 km ph

A nightclub has approximated the demand for their Thursday night drink special by p^2+200q^2=177​, where p is the price​ (in dollars) and q is the quantity demanded​ (in thousands). Find and interpret when the price is ​$ 7 and the demand is 800 drinks.

Answers

Answer:

Step-by-step explanation:

Given the approximate demand function of night drink expressed as;

p^2+200q^2=177​,

p is the price​ (in dollars) and;

q is the quantity demanded​ (in thousands).

Given

p = $7

q = 800

Required

dq/dp

Differentiating the function implicitly with respect to p shown;

2p + 400d dq/dp = 0

400q dq/dp = -2p

200qdq/dp = -p

dq/dp = -p/100q

substitute p and q into the resulting equation;

dq/dp = -7/100(800)

dq/dp = -7/80000

dq/dp = -0.0000875

This means that the rate of change of quantity demanded with respect to the price is  -0.0000875

Find the value of x if C is the midpoint of line segment AB, AC=4x+5, and
AB=78?

Answers

Answer:

x =  8.5

Step-by-step explanation:

AC + CB = AB

As C is the midpoint AC = CB = 4X + 5

AC + CB = AB

4x + 5 + 4x + 5 = 78

4x + 4x + 5 + 5  = 78            {Combine like terms}

            8x + 10 = 78            {Subtract 10 from both sides}

                    8x = 78 - 10

                    8x = 68

                      x = 68/8

                      x =  8.5

Each correct answer is worth 134 points, and each incorrect answer is worth −14 points. If he gets 58 questions correct and 22 questions incorrect, does Nevan win? How many points does he score?

Answers

Answer:

i. Yes, Nevan won.

ii. Nevan scored 7464 points.

Step-by-step explanation:

Given: each correct answer = 134 points

           each incorrect answer = -14 points

Since he got 58 questions correctly, then;

His number of points = 134 x 58

                                   = 7772 points

Also, he got 22 incorrect questions, then;

His number of points = -14 x 22

                                   = -308

Nevan's total points = 7772 + (-308)

                                 = 7772 - 308

                                 = 7464

Nevan scored 7464 points.

Mary is painting pumpkins to earn money. She plans on selling each pumpkin for $7.50. She currently has $200 in her savings account. Is the amount of money in her bank account proportional to the number of pumpkin she sells?

Answers

Answer: No. It's not proportional

Step-by-step explanation:

The direct proportion in mathematics is expressed as:

y = kx

where

y = $200

k = constant

x = $7.50

We then solve for k

y = kx

200 = 7.50k

k = 200/7.50

k = 26.67

Since k isn't a whole number, then the amount of money in her bank account proportional to the number of pumpkin she sells.
