Answers

Answer 1

Answer:

r = 12.89

Step-by-step explanation:

18(2) + 15(3) = 81 = C

C = 2πr

81 = 2πr

81/2 = πr

r = 81/2π ≈ 12.89

Given acd and abe, what is ab?

Answers

Answer:

AB  = 8

Step-by-step explanation:

Using the similarity theorem of a triangle;

AC/AD = AB/AE

AC = AB + BC and AD = AE + ED

AB + BC/AE + ED = AB/AE

Substitute the given values

AB+12/15 = AB/6

Cross multiply

6(AB+12) = 15AB

6AB + 72 = 15AB

15AB - 6AB = 72

9AB = 72

AB = 72/9

AB = 8

What percentage of the pieces was he missing if he had 250 puzzle pieces and was missing 15 What percentage of the pieces was he missing

Answers

Answer:

Percentage of missed puzzle pieces = 6%

Step-by-step explanation:

Total number of puzzle pieces = 250

Missed puzzle pieces = 15

Percentage of the missing puzzle pieces = [tex]\frac{\text{Missed puzzle pieces}}{\text{Total number of puzzle pieces}}\times 100[/tex]

= [tex]\frac{15}{250}\times 100[/tex]

= 15 × 0.4

= 6%

Therefore, percentage of missed puzzle pieces = 6%

solve the system of equations by adding. checking your answer
2x+2y=2
3x-2y=43
the solution of the system is ( , )​

Answers

Answer:

Step-by-step explanation:

This is very easy, because the coefficients of the y terms are 2 and -2. You can easily eliminate the y terms by adding the equations together:

2x + 2y = 2

3x - 2y = 43

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

5x + 0y = 45,  so x = 9

Use the value of x to solve for  y:

2(9) + 2y = 2

y = -8

(x,y) = (2, -8)
