In the year 2009, a company made $8.4 million in profit. For each consecutive year
after that, their profit increased by 14%. How much would the company's profit be in
the year 2011, to the nearest tenth of a million dollars?

Answers

Answer:

$10.8 million or 10,752,000

Step-by-step explanation:

14% of 8,400,000 is 1,176,000

t = time in years

In one year, the company would make 8,400,000+(t*1,176,000)

In 2 years they make 8,400,000+(2*1,176,000) = 10,752,000

now round 10,752,000 to the nearest hundred thousand, which is 1/10 of 1,000,000.

Kendra and Dalisay practice archery, Kendra hits the target 3 times for
every 5 misses Dalisay hits the target 5 times for every 7 misses.
Who hits the target more?

Answers

Answer:

Dalisay

Step-by-step explanation:

3/5=0.6 (Kendra)

5/7≈ 0.75 (Dalisay)

5/7>3/5, so Dalisay hits the target more.

The probability of Dalisay hitting the target is more.

What is probability?

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

According to the given problem,

Kendra hits target 3 times for 5 misses

Probability = [tex]\frac{3}{5}[/tex]

                  = 0.6

Dalisay hits target 5 times for every 7 misses

Probability = [tex]\frac{5}{7}[/tex]

                  = 0.71

Hence, we can conclude that Dalisay hits the target more.

At the beginning of the year, Alyssa had $100 in savings and saved an additional $7
each week thereafter. Colton started the year with $55 and saved $10 every week. Let
A represent the amount of money Alyssa has saved t weeks after the beginning of the year and let C represent the amount of money Colton has saved t weeks after the
beginning of the year. Write an equation for each situation, in terms of t, and determine the famount of money Alyssa and Colton have saved in the week that they have the same amount of money saved.

Answers

Answer:

A = 7t + 100 and C = 10t+55 are the equations for each situation and they both will have an amount of $205 after 15 weeks.

Step-by-step explanation:

Given that:

Alyssa started savings with $100

Saved amount each week = $7

A = Amount of money Alyssa have

t = number of weeks

A = 7t + 100

Colton started savings with $55

Saved amount each week = $10

C = 10t + 55

For same amount;

A = C

7t+100 = 10t+55

100-55=10t-7t

45=3t

3t=45

Dividing both sides by 3

[tex]\frac{3t}{3}=\frac{45}{3}\\t=15[/tex]

Putting t=15 in Alyssa's equation

A = 7(15)+100

A = 105+100 = $205

Hence,

A = 7t + 100 and C = 10t+55 are the equations for each situation and they both will have an amount of $205 after 15 weeks.

Rick is buying a $115 tennis racquet from a sporting goods store. If the racquet is on sale for 35% off and sales tax is 8%, how much will he pay in total?

Answers

Answer:

$79.65

Step-by-step explanation:

115-40.25= 73.75


73.75 x 0.08 = 5.90


73.75 + 5.90 = 79.65



     

Rick will pay 80.73 dollar in total.

What is the fundamental principle of multiplication?

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

Given that Rick is buying a $115 tennis racquet from a sporting goods store.

If the racquet is on sale for 35% off and sales tax is 8%,then

First,we need to find 35% of 115.

35% as a decimal is 0.35

0.35 x 115 = 40.25

Now, subtract 40.25 from 115;

115 - 40.25 = 74.75

Now, the sales tax, find 8% of 74.75.

8% as a decimal is 0.08

0.08 x 74.75 = 5.98

Now, subtract add 5.98 to 74.75;

5.98 + 74.75 = 80.73

Therefore, he will pay 80.73 dollar in total.

Answer:

BF = 18

Step-by-step explanation:

In triangle BCD, H is the Centroid.

Centroid of a triangle divides the median in the ratio 2 : 1.

Therefore, BH : HF = 2 : 1

Let BH = 2x & HF = x

Since, HF = 6.... (given)

So, x = 6

2x = 2*6 = 12

BH = 12

Now,

BF = BH + HF = 12 + 6

BF = 18

Explain how to write an equivalent expression by combining like terms.

w + 10 + w – 4

Answers

Answer:

To combine like terms, add the variable terms together and then add the constants together. When you combine the variable terms, you have 1w + 1w, which is 2w. When you combine the constants, you have 10 – 4, which is 6. The equivalent expression is 2w + 6.

Step-by-step explanation:

Answer:

add both "w" which equals 2w. Then add 10 and -4 which is 6. So the answer is 2w+6... I'm pretty that's the answer make sure to double-check though

A square has a perimeter of 100m. what is the length of each side?

Answers

It would be 25m. This is because for perimeter you have to add up all the sides. And really since you have a square you could do 100 divided by 4 and get your answer.

Answer:

25m

Step-by-step explanation:

The perimeter of a square= 4L (L=length of the side)

so L=perimeter /4

The current I in an electrical conductor varies inversely as the resistance R of the conductor. The current is 1/5 ampere when the resistance is 8750 ohms. What is the current when the resistance is 17150 ​ohms?

Answers

Answer:

0.102048 ampere

Step-by-step explanation:

I α k / R

Current = 1/5 ; R = 8750

What is the current when the resistance is 17150 ​ohms

First obtain the value of k :

I = k/R

I = 1/5 ampere = 0.2 A

0.2 = k / 8750

k = 1750

What is the current when the resistance is 17150 ​ohms

I = 1750 / 17150

I = 0.1020408

I = 0.102048 ampere

The length and width of a rectangle, in terms of x, are x + 3 and 2x − 17, respectively. The area of the rectangle is 234 square units. (a) (6 points) DETERMINE the possible values of x

Answers

The possible values of x of a rectangle with length and width of x + 3 and 2x - 17 respectively is 15

Area of a rectangle

area of a rectangle = lw

where

l  =lengthw = width

Therefore,

length = x + 3

width = 2x - 17

area = 234

Therefore,

234 = (x + 3)(2x - 17)

2x² - 17x + 6x - 51 = 234

2x² - 11x - 51 - 234 = 0

2x² - 11x - 285 = 0

Therefore,

(x - 15)(2x + 19)

Hence,

x = 15 or x = - 19 / 2

we can only use positive values. Therefore, x = 15
