Answer:

The cost of buying used video games from both companies will the same at the 4th video game.

Step-by-step explanation:

Gamestop equation: 7x

Gamefly equation: 3x + 16

7x = 3x + 16

Subtract 3x from both sides;

4x = 16

Divide both sides by 4x

x = 4

Answer:

$7.09

Step-by-step explanation:

Multiply 5.1 * 1.39 which equals 7.089. Then round to the nearest hundreth which will be 7.09.

Answer: 7.1 meters

Step-by-step explanation:

Given that :

Height of platform from which Doug dived = 5 meters above water

Doug's position after diving = 2.1 meters below water surface

How far does Doug's dive take him?

Distance above water surface to water surface = 5m

Final position to water surface = 2.1 meters

Hence, total distance covered after dive ;

5 meters + 2.1 meters = 7.1 meters

Answer:

D

Step-by-step explanation:

Estimating 1,596 will give you 1,600. Estimating 42 will give you 40. Dividing 1,600 ÷ 40 will give you 40. So, the answer would be D.

Step-by-step explanation:

The marked price of an article is 25% above the SP and the CP is 20% below the selling price. What is the rate of discount and the profit percentage?

Let C, M & S denote cost-price, marked-price & sell-price respectively of the article.

Hence from above data we get following relations,

M = (1 + 25/100)*S = 1.25*S ….. (1a)

C = (1 - 20/100)*S = 0.80*S ….. (1b)

From (1a) we get,

S = (100/125)*M = (4/5)*M

or S = (1 - 1/5)*M = (1 - 20/100)*M ….. (2a)

From (1b) we get,

S = (100/80)*C = (5/4)*M

or S = (1 + 1/4)*C = (1 + 25/100)*C ….. (2b)

Therefore

It is evident from (2a) that

the discount percentage = 20% [Ans]

It is evident from (2b) that

the profit percentage = 25% [Ans]

Answer:

Triangle QNR is congruent to Triangle RMQ by ASA congruence

Step-by-step explanation:

In Triangle QNR and Triangle RMQ,

QR = QR  ( Common )

Angle MRQ = Angle NQR ( given )

Angle MQR = Angle NRQ ( Isoceles Triangle Property )

Therefore, Triangle QNR is congruent to Triangle RMQ by ASA congruence.

Complete Question:

You plant an 8-inch spruce tree that grows 4 inches per year and a 14-inch hemlock tree that grows 6 inches per year.

The initial heights are shown.

Write a system of linear equations that represents this situation.

Answer:

[tex]s(x) = 8 + 4x[/tex]

[tex]h(x) = 14 + 6x[/tex]

Step-by-step explanation:

Given

Spruce Tree (s):

[tex]Initial\ Height = 8[/tex]

[tex]Growth = 4[/tex] (yearly)

Hemlock Tree (h):

[tex]Initial\ Height = 14[/tex]

[tex]Growth = 6[/tex] (yearly)

Required

Represent as system of linear equations

Let the number of years be x.

In both cases, the equation can be formed using:

[tex]Equation = Initial\ Height + Growth * x[/tex]

For Spruce Tree (s):

[tex]s(x) = 8 + 4 * x[/tex]

[tex]s(x) = 8 + 4x[/tex]

For Hemlock Tree (h):

[tex]h(x) = 14 + 6 * x[/tex]

[tex]h(x) = 14 + 6x[/tex]

Hence, the equations are [tex]s(x) = 8 + 4x[/tex] and [tex]h(x) = 14 + 6x[/tex]

Answer:

[tex]Total = \$73[/tex]

Step-by-step explanation:

Given

[tex]Three\ 8lb = \$2.25/lb[/tex] --- Dog Food

[tex]Two\ 4lb = \$1.75/lb[/tex] ----- Cat Food

[tex]Three\ \frac{1}{4}lb = \$6.98[/tex] -------- Fish Food

Required

Determine the amount spent

For Dog Food

[tex]1\ lb = \$2.25[/tex]

Amber bought 8lb.

So, that is:

[tex]8 * 1\ lb = \$2.25 * 8[/tex]

[tex]8\ lb = \$18[/tex]

He bought 3 of those;

[tex]Cost = 3 * \$18[/tex]

[tex]Cost = \$54[/tex]

For Cat Food

[tex]1\ lb = \$1.75[/tex]

Amber bought 4lb

So, that is:

[tex]4 * 1\ lb = 4 * \$1.75[/tex]

[tex]4\ lb = \$7[/tex]

He bought 2 of those;

[tex]Cost =2 * \$7[/tex]

[tex]Cost =\$14[/tex]

For Fish Food

[tex]1\ lb = \$6.98[/tex]

Amber bought 1/4lb

So, that is:

[tex]\frac{1}{4} * 1\ lb = \$6.98 * \frac{1}{4}[/tex]

[tex]\frac{1}{4}\ lb = \$1.745[/tex]

He bought 3 of those;

[tex]Cost = 3 * \$1.745[/tex]

[tex]Cost = \$5.235[/tex]

Total amount spent  is:

[tex]Total = \$54 + \$14 + \$5.235[/tex]

[tex]Total = \$73.235[/tex]

[tex]Total = \$73[/tex] (approximated)

Answer:

5 1/8 - 2 5/6

Step-by-step explanation:

Answer: 2  7 /24

Answer:

2 7/24

Step-by-step explanation:

let’s go ahead and make these fractions have the same denominator.

1/8 and 5/6

what multiple do they share?

8 * 3 = 24

6 * 4 = 24

we will change their denominators to 24.

Now to change the numerator you have to multiply it by what you multiplied the denominator by:

1/8 * 3/3 = 3/24

5/6 * 4/4 = 20/24

now we will add the whole numbers to the fraction:

5/1 * 24/24 = 120/24

2/1 * 24/24 = 48/24

now add these to the correct fraction:

120/24 + 3/24 = 123/24

48/24 + 20/24 = 68/24

Now subtract!

123/24 -68/24 = 55/24

Simplify:

55/24 = 2 7/24

Answer:

8 gallons per minute

Step-by-step explanation:

24 gallons in 3 minutes

you divide 24 by 3 which is 8

40 gallons in 5 minutes

you divide 40 by 5 which is 8

the relationship is that in both the answer was 8 as in 8 gallons per minute

Answer:

Step-by-step explanation:

From the figure attached,

Coordinates of the vertices of the given rectangle ABCD,

A(3, 6), B(12, 6), C(12, 1) and D(3, 1)

Rule for the reflection of a point across x-axis,

(x, y) → (x, -y)

After reflection of the given rectangle across x-axis image points will be,

A(3, 6) → A'(3, -6)

B(12, 6) → B'(12, -6)

C(12, 1) → C'(12, -1)

D(3, 1) → D'(3, -1)

Now we can plot these points on the graph to get the image of rectangle ABCD.

Answer:

1120000 attendees

Step-by-step explanation:

Given that:

Yearly Average attendance = 2.8 * 10^5 people

How many attendees can be expected to attend over 4 years

Average Yearly attendees * 4

(2.8 * 10^5) * 4

= 2.8 * 4 * 10^5

= 11.2 * 10^5

= 1120000 attendees

Answer:

-0.0936538462

Step-by-step explanation:

Start by solving the right side of the equation

1 - 2.87 = -1.87

now we have:

3 + 5.2c = -1.87

subtract 3 from both sides to get:

5.2c = -4.87

divide both sides by 5.2 to get:

-0.0936538462

hope that's what you're looking for! :)

Answer:

Step-by-step explanation:

Given the height of the object as it drops from the observation deck expressed as;

h= -16t^2+152

To determine the the time it will take the object to be 8 feet above the valley floor, we will substitute h = 8 into the equation and calculate t as shown;

8 = -16t^2+152

subtract 8 from both sides

8-8 = -16t^2+152-8

0 =  -16t^2+144

0-144 =  -16t^2

-144 = -16t^2

16t^2 = 144

Divide both sides by 16;

16t^2/16 = 144/16

t^2 = 9

t = √9

t = 3seconds

Hence it will take 3 seconds for the object to be 8 feet above the valley floor
