nordsb [41]

The percentage of trench coats sold increased by 23. 3%. therefore, option D is correct.

<h3>What is the percentage?</h3>

A percentage is a minimum number or ratio that is measured by a fraction of 100.

First, we need to subtract the final from the initial, then divide the difference by the initial, then multiply your answer by 100 to get the percentage

the final is 127, and the initial is 103

127 - 103 = 24

24/103 = 0.233

0.233 x 100

= 23.3%

Thus, The percentage of trench coats sold increased by 23. 3%.

Cindy purchased 100 bricks. Each brick is within 1/8 inch of the advertised length of 8 inches. Cindy will line the bricks up en
AURORKA [14]
If each brick is within 1/8 inches of 8 inches, then that's an error of
 \frac{(\frac{1}{8})}{8} =\frac{1}{64}
If we then take the total length if each brick is 8 inches,
100*8=800
Then take 1/64 of this
800*\frac{1}{64}=12.5[tex] So the upper and lower bounds are 12.5 inches either side of 800 inches 787.5, and 812.5 So we can say that [tex]787.5 \leq x \leq 812.5
Which would be the answer to part a. parts b and c would be the lower and upper bounds, so 787.5 and 812.5 respectively
Hope this helps

Answer:

16 turtles

20 frogs

32 fish

Step-by-step explanation:

let 't' = # turtles

let '4 + t' = # frogs

let '2t' = # fish

t + 4 + t + 2t = 68

4t + 4 = 68

4t = 64

t = 16 turtles

4 + 16 = 20 frogs

2(16) = 32 fish
