I need help learning to do this IM GIVING EXTRA POINTS!!!

Answers

Answer 1

Step-by-step explanation:

So Scientific Notation is like this.

Ya got a big number that has of 0s . Let's just throw out 69,000,000,000,000

You take the other numbers that arent 0s. Take the first number and put a "." in between it and the second number. So, in this case, you have 6.9, like this.

You then count the number of 0s and +1. So in this case, you'll have 12+1. Which is 13.

You then take the 6.9 and note it with a *10. You then take the 13 and put it on the 10 as an exponent. So in the end youll have 6.9*10^13.

Hopefully, this helps.

With love,

The marked price of an article is 25% above the selling price and the cost price is 20% below the selling price. Find the rate of discount and the profit percentage.​

Answers

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]

The average attendance of a yearly Winter Wonderland exhibit at an amusement park is 2.8 × 10 5 people. How many people can be expected to attend over 4 years?

Answers

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

Gamestop charges only $7 per used video game. Gamefly charges a one time fee of $16 plus an additional $3 per used video game. Write and solve an equation to find when the cost of buying used video games from both companies below will be the same.

Answers

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

An observation deck extends 202 feet out above the valley. The deck sits 152 feet above the valley floor. If an object is dropped from the observation deck, it's height h in feet, after t seconds, is given by h= -16t^2+152. How long will it take for the object to be 8 feet above the valley floor?

Answers

Answer:

3 secs

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

Amber bought three 8 pound bags of dog food at $2.25 per pound, two 4 pound bags of cat food at $1.75 per pound, and three 1/4 pound bags of fish food at $6.98 per pound. Approximately how much did Amber spend on pet food?

Answers

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)

Help please I’ll give you 25 points

Answers

Answer: Choice D) [tex]y = \pm \sqrt{x+5}[/tex]

The steps to finding the inverse will have us swap x and y. Afterward, we solve for y

[tex]y = x^2 - 5 \\\\x = y^2 - 5 \\\\x+5 = y^2 \\\\y^2 = x+5 \\\\y = \pm \sqrt{x+5} \\\\[/tex]

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

Extra info:

The inverse relation is not a function because of the plus minus. For instance, plugging x = 4 into [tex]y = \pm \sqrt{x+5}[/tex] leads to y = -3 and y = 3 simultaneously. You would have to apply a domain restriction on [tex]y = x^2-5[/tex] to make it a one-to-one function, to make the inverse a function. One possible domain restriction is [tex]x > 0[/tex] which would lead to the inverse function [tex]y = \sqrt{x+5}[/tex]

Doug dives from a platform that is 5 meters above water. His dive takes him 2.1 meters below the surface of the water. How far does Doug's dive take him?

Answers

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

Use the polygon tool to graph the reflection of this rectangle across the x-axis.

Answers

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.
