The answer is k-2/9 because it says that k is decreased which means u substrate and then it's says the quotient of 2 and 9 which means that u divide so then u get 2/9
Answer:
15
Step-by-step explanation:
using the 3 : 4 : 5 triangle triple:
we see that this triangle follows the same ratio
9:12 = 3:4, so the hypotenuse = 5*3 = 15
ANSWER: 15
21. The number who responded is 600 -150 = 450. Expressed as a fraction of the total, that is
450/600 = (150*3)/(150*4) = 3/4
22. Total fabric used is
6*(3 1/6) +8*(2 3/4) = 19 +22 = 41 . . . . yards
Fabric unused is . . .
50 yd -41 yd = 9 yd
23. The problem statement is ambiguous. We suppose it is intended to say that the stock increased by 1/4 of its original value. In that case, the present value is
$2000 +$2000*(1/4) = $2500
_____
An alternate interpretation of the statement is that the amount of increase was 1/4. In that case, the present value is
$2000 + 0.25 = $2000.25
The second choice
For it’s just rearranged
Hi!
Using y = mx + b form, where m is the slope and b is the y-intercept, we get the equation: y = -2x + 0.3
Hope this helps! :D
