Answer:

Bernie, Chrissy, Dina and Frank

Step-by-step explanation:

if all 73 tickers are sold, the theatre makes $438 so each ticket is worth $438/73

this equals to $6.00 for one ticket

this means that Bernie, Chrissy, Dina and Frank have enough money to see the movie

Answer:

Bernie, Chrissy, Dina, and Frank are able to go.

Step-by-step explanation:

The question is not entirely clear. I take it that 73 tickets will bring in 438 dollars. If that is so, each ticket is selling for the solution of this proportion.

x / 1 = 438/73       Just do the division on the right

x = 6.00 dollars.

So Amanda will not be able to go.

Even will not be able to go.

Everyone else can.

The x-intercepts of the equation represent the points where the height of the toss is equal to 0. The bocce ball lands on the ground at a horizontal distance of 0 feet and 4 feet.

The x-intercepts of the graph of the equation represent the points where the height of the toss is equal to 0.

In other words, these points represent the horizontal distance where the bocce ball lands on the ground.

o find the x-intercepts, we set y=0 and solve the equation:

0=-x^2+4x

x(x-4)=0

Therefore, the x-intercepts are x=0 and x=4.

This means that the bocce ball lands on the ground at a horizontal distance of 0 feet and 4 feet.

The equation of the line passing through the points (0, 17) and (0, 0.51) is x = 0.

The equation of the line that passes through the points (0, 17) and (0, 0.51) can be found using the slope-intercept form of a linear equation, which is y = mx + b. To find the slope (m), we use the formula (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are the coordinates of the two points.

Answer:

F  $185

G 12 weeks

Step-by-step explanation:

Assuming your equation is correct

y = -35x +500

We want to let x=9

y = -35(9) +500

y = -315+500

y =185

Jason will have $185  after 9 weeks

If he has 80 dollars left we put that in for y and solve for x

80 = -35x +500

Subtract 500 from each side

80-500 = -35x +500-500

-420 = -35x

Divide each side by -35

-420/-35 = -35x/-35

12 = x

After 12 weeks he will have 80 dollars left

Answer:

x=12 makes (X-12)/(x-8) equal to zero

x=8 makes (X-12)/(x-8)  undefined

Step-by-step explanation:

(x-12)/(x-8) = 0

The  first step is to multiply each side by x-8

 (x-8) *(x-12)/(x-8) = 0 * (x-8)

This cancels the denominator.  x≠ 8 because the denominator would equal 0 and then it becomes undefined.

x-12 = 0

Add 12 to each side

x-12+12 = 0+12

x = 12

Answer: The car would need 0.3 gallons of fuel to travel 20km.

Step-by-step explanation: 40mile x 1.6km = 64km

                                           1 gallon     1 mile    1 gallon

20km ÷ 64km = 0.3125

Answer:

In 0.3 gallon of fuel, the car will travel 20 km.

A is the correct option.

Step-by-step explanation:

We have been given that in 1 gallon of fuel the car can travel 40 miles.

Now, 1 mile = 1.6 km.

Hence, in 1 gallon the car travel 40×1.6 = 64 km

Let the car will consume x gallons of fuel to travel 20 km.

Thus, we have the equation

[tex]\frac{1}{64}=\frac{x}{20}[/tex]

ON solving for x

[tex]x=\frac{20}{64}\\\\x=0.3[/tex]

Therefore, in 0.3 gallon of fuel, the car will travel 20 km.

A is the correct option.

Answer:

The cost of a hamburger is 2.25

The cost of fries is 1.75

Step-by-step explanation:

Let h = cost of hamburgers

let f= cost of fries

4h + 3f = 14.25

3h+5f = 15.50

I will solve these by elimination

Multiply the 1st equation by 3

3(4h + 3f )= (14.25)3

12h +9f = 42.75

Multiply the 2nd equation by -4

-4(3h+5f )= -4(15.50)

-12h - 20f = -62

Add the modified equations together

12h +9f = 42.75

-12h - 20f = -62

----------------------------

-11 f = -19.25

Divide each side by -11

-11f/-11 = -19.25/-11

f = 1.75

Now we need to find the cost of the hamburger

3h+5f = 15.50

Substitute the cost of the fries in

3h + 5(1.75) = 15.50

3h +8.75 + 15.50

Subtract 8.75 from each side

3h = 15.5-8.75

3h =6.75

Divide by 3

3h/3 =6.75/3

h = 2.25

Answer:

5 Hours

Step-by-step explanation:

Given :- 2 hours can be earned each day if she eats all of her vegetables and does all of her chores.

Saved hours at the start of the week = 3 hours

Hours earned in 4 days = 2 hours × 4

                                       = 8 hours

Hours used in 4 days = 6 hours

Hours left after 4 days = Saved hours at the start of the week + Hours earned in 4 days - Hours used in 4 days

Hours left after 4 days = 3 + 8 - 6

                                       = 5 hours

The total amount you would pay at the physical store after all discounts, taxes, and fees have been applied is [tex]{128.36} \)[/tex].

Let's go through the calculations again to find the final cost at the physical store after all discounts, taxes, and fees.

Physical Store Pricing:

- Batteries: 2 packs at $5.99/pack

- Stereo: 1 system at $100.00

- CDs: 3 CDs at $7.95 each

Discounts and Taxes in the Physical Store:

1. 10% Off Coupon: This coupon applies to the total purchase amount before tax.

2. Sales Tax: 5% sales tax applies to the total purchase amount after applying discounts.

Calculation Steps:

Step 1: Calculate the total cost of items before discounts and tax:

- Batteries: 2 packs × $5.99/pack = $11.98

- Stereo: $100.00

- CDs: 3 CDs × $7.95/CD = $23.85

Total before discounts: $11.98 + $100.00 + $23.85 = $135.83

Step 2: Apply the 10% off coupon:

- 10% of $135.83 = $13.583

- Total after 10% off: $135.83 - $13.583 = $122.247

Rounded to two decimal places: $122.25

Step 3: Apply the 5% sales tax:

- 5% sales tax on $122.25:

[tex]\[0.05 \times 122.25 = 6.1125\][/tex]

Rounded to two decimal places: $6.11

Step 4: Calculate the final cost at the physical store:

- Total cost after tax: $122.25 + $6.11 = $128.36

The complete question is

You are buying batteries, a stereo, and some CDs from the I.B. Electronics store. You can buy from this store online or in a physical store. You have a coupon for 10% off that can only be used in the physical store and a $5.00 off coupon that can only be used online. The sales tax of 5% only applies to the physical store.

Dividing 0.8 by 10² moves the decimal two places to the left, resulting in 0.008. Multiplying 0.8 by 10² moves the decimal two places to the right, resulting in 80. Thus, the two operations produce different magnitudes of the original number.

Understanding the Relationship Between 0.8 ÷ 10² and 0.8 × 10²:

In mathematics, it's essential to understand how operations involving powers of ten affect numbers. Let’s break down the operations:

0.8 ÷ 10²: When you divide a number by 10 raised to the power of 2 (which is 100), you move the decimal point two places to the left. So, 0.8 ÷ 100 = 0.008.

0.8 × 10²: When you multiply a number by 10 raised to the power of 2, you move the decimal point two places to the right. So, 0.8 × 100 = 80.

We can conclude that 0.8 ÷ 10² results in moving the decimal to the left, making the number smaller (0.008), while 0.8 × 10² results in moving the decimal to the right, making the number larger (80).

The 10% of people  who received the email are in the original 15 people.

A number or ratio that can be expressed as a fraction of 100 is called a percentage. Divide the number by its whole number and multiply it by 100 if we have to figure out the percentage of that number. Consequently, the percentage represents one part per hundred. The word "per 100" means "per percent." The number "%" is used to symbolize it.

Given email received by people = 15

sent to 3 different people

the number of people have email = 15 x 3 = 45

then 45 people send it to 2 new

number of people email have = 45 x 2 = 90

total number of person who have email = 15 + 45 + 90 = 150

To the percent of 15 people in a group of 150 people by diving 15 by 150

15/150(100) = 10%

Scale Factor (SF)

The scale factor is the number you multiply the real by to get the model, it can also be used the other way, for instance if a map's SF was 1in=1ft (or times 12) every 2 inches on the map would be 24 inches (or 2 ft) in real life.

If the SF is lower than 1 (a decimal like .7 for instance) then the result will be smaller (for Real to Model)

for the first one, 80 times the SF will equal 25

80 * X = 25

^Here is it in equation form, X being the scale factor

isolate X (or find what x equals by getting it by itself)
