A rhombus has a perimeter of 217 cm. what is the length of each side of the rhombus

Answers

Answer 1

Answer: A rhombus has 4 equal sides.
The perimeter is the side lengths added together.

P = s + s + s + s
P = 4s
217 = 4s

Divide by 4 to find the length of one side.

s = 54.25 cm

Len walks 3/10 mile in the morning and 2/5 mile in the afternoon len says that he walks a total of 5/15 mile in the morning and afternoon

Answers

Hey There!

Steps to solve (Please note, steps will be in numerical order.)

1.To start off you have to find the lCD of $(3)/(10)$ and $(2)/(5)$ . So, the LCD of both fractions is ten.

2. Now, rewrite the fraction $(3)/(10)$ to $(4)/(10)$ , since the lcd is 10 you have to multiply the numerator and denominator of $(2)/(5)$ by two.

3. You only have to add $(3)/(10)$ + $(4)/(10)$

4. First, add the numerators 3+4 which is 7. Remember when adding fractions the denominator stays the same.

5. In conclusion, you're final answer should be $(7)/(10)$ , so Len's statement was false and he walked total $(7)/(10)$ steps.

Mr.Jenkins wants to distribute 40 fliers. He distributed 30 fliers so far. What percent of the total number of fliers has Mr. Jenkins distributedÉ

Answers

$(30)/(40)= (3)/(4) \n\n (3)/(4) = (x)/(100) \n\n4*25=100\n3*25=75\n\n(75)/(100)\n\n75\%$

Just put 30 over 40. Now you have $(3)/(4)$
If you put that in decimal form it's .75. Now convert it to a percent and get 75%

Laketown had 215 inches of snowfall last year, but only 155 inches this year. What was the percent decrease in snowfall for Laketown to the nearest percent? A. 28% B. 39% C. 72% D. 139%I think A

Answers

Okay, so FIRST you would subtract 215 - 155, which is 60, and THEN divide it by 215, so 60 divided by 215 = 0.27, and rounded that is 0.28, then you move the decimal two places to the right to make it a percentage so your answer would be A., 28%
I hope I helped! =D

*lets do this step by step*

1st. subtract
215 - 155 = 60

2nd. divide
60 ÷ 215 = 0.2790697674

3rd. we round
0.2790697674 = 0.28

answer? A.) 0.28

How could you change the equation here so it has infinitely many solutions? What would infinitely many solutions mean in terms of the situation? If the equation were 6x + 2 = 5x + 17 would there be one unique solution? What is it, and what would it mean in terms of the situation

Answers

Answer:

there is likely no way you can switch it around but you are correct there is no plausible solution to the proble so itd be nothing

Step-by-step explanation

Answer:

Evaluate: 6x+2=5x+17

Move the variable to the left side: 6x+2−5x=17

Subtract the terms

More Steps: x+2=17

Move the constant to the right side: x=17−2

Solution: x=15
