Answer: x=8

Step-by-step explanation:

Since we are given that ∠ABC and ∠DBC are complementary angles, we know that adding them together should give us 90°. We can use this to solve for x.

6x+13+4x-3=90         [combine like terms]

10x+10=90                 [subtract both sides by 10]

10x=80                       [divide both sides by 10]

x=8

Now, we know that x=8.

ludmilkaskok [199]

Answer:

126 tiles

Step-by-step explanation:

The while tiles are 3/4 of a foot (or 9 inches) x 9 in, so their area is 81 sq in. There are 14 blue tiles, so 14 x 81 = 1134 sq inches that need to be covered.

Each tiles is 3 x 3, so its area is 9 sq in. 1134 / 9 = 126 tiles

121 of the green beans will be shorter than 13 centimeters.

First, we need to evaluate the expression below to find the z-score.
(13 - 11.2) / 2.1. = 0.86

The matching percent for this z-score is 0.8051.

Multiplying 0.8051 by 150 gives us about 121 green beans.
