Answer:

x= 25

Step-by-step explanation:

There are 180 degrees in a triangle

100 + 55 + x = 180

155 + x = 180

Subtract 155 from 180

x = 25

Please help ASAP!! I'm in. a google meet rn and need to prove I got this question right

Aleks04 [339]

Answer:

x = 5.4

Step-by-step explanation:

(This question has already been answered, but both of the incorrect ones were deleted, so for future reference...)

Fig A is a scale image of Fig D. These two quadrilaterals are similar, and thus, the side lengths of corresponding sides are proportional. Set the proportion x/3 = 7.2/4 (you could alternatively write it as x/7.2 = 3/4 but for the simplicity's sake, and assuming anyone who has this problem would already know how to solve proportions like these...)

7.2/4 = 1.8

x/3 = 1.8

now multiply both sides by 3 to get x = 5.4

A garden is in the shape of a square with a perimeter of

ElenaW [278]

The perimeter of a square is the sum of its sides and they are all equal, so to obtain the length of each of them we divide the perimeter of the first fence between 4:

P1= 64 feet/4 sides

P1= 16 feet

Then, the length of each side of the second fence will increase 2 feet at each end, as shown in the figure. We have then that the perimeter of the second fence is:

P2 = 20 feet x 4 sides

P2 = 80 feet

The sum of the perimeters of both fences is:

PT = P1 + P2

PT = 64 feet + 80 feet

PT = 144 feet

Total cost = 1.17 $ x 144 feet

Total cost = 168.48 $

The total cost of the fences was $ 168.48

What is a formula for the nth term of the given sequence? 20,23, 26...

lord [1]

Answer:

17 + 3n

Step-by-step explanation:

20, 23,26 ..............

This is an arithmetic series

First term = a = 20

Common difference = second term - first term

d = 23 - 20 = 3

nth terms = a + (n-1)*d

= 20 + (n -1) *3

= 20 + n*3 - 1*3

= 20 + 3n - 3

= 20 - 3 + 3n

= 17 + 3n
