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

=100/4=25m

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

g(x) = 2x + 1
The slope of f(x) is less than the slope of g(x). The y-intercept of f(x) is equal to the y-intercept of g(x).
The slope of f(x) is greater than the slope of g(x). The y-intercept of f(x) is equal to the y-intercept of g(x).

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

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.

Answers

Answer:

Step-by-step explanation:

7x - 2(7x - 9) = 2(-6x + 4)                      Remove the brackets on both sides.

7x - 14x + 18 = -12x + 8                         Combine like terms

-7x + 18 = -12x + 8                                Add 12x to both sides

-7x+12x + 18 = 8                                   Combine like terms on the left

5x + 18 = 8                                           Subtract 18 from both sides

5x = 8 - 18

5x = -10                                                Divide by 5

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.

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.

Therefore, BH : HF = 2 : 1

Let BH = 2x & HF = x

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

So, x = 6

2x = 2*6 = 12

BH = 12
