Answer:
d. 2.4 in
Step-by-step explanation:
So initially w/o frame the area was 5 x 7 = 35 sq in.
Now we have to add the width of the frame to both dimensions.
(5+w)(7+w) = 69.56 sq in
35 + 7w + 5w + w² = 69.56
w² + 12w + 35 = 69.56
w² + 12w - 34.56 = 0
I use the quadratic formula to solve this (x = -b±√b²-4ac / 2a). I cheat by using a quadratic program on the calculator :,)
w = 2.4
w = -14.4
Since we can't have a negative width, the answer must be <u>w = 2.4 inches.</u>
You can also just plug the answer choices one-by-one into the calculator with guess-and-check because this is multiple choice.
Provide the measurements of the court in the book, please.
Answer:
A.
Step-by-step explanation:
each one is $1.03
so if you want 2 stamps they would be $2.06
The probability is 56/100 or 56%. Because they only got 44% of their previous throws, the probability that they'll miss the next one is 56%.
517284 books have been sold to date.
Step-by-step explanation:
Given,
Copies sold in first month = 41900
This represents 8.1% of copies sold to date.
Let,
x be the number of copies that have been sold to date.
8.1% of x = 41900
Dividing both sides by 0.081
Rounding off to nearest whole number
x = 517284
517284 books have been sold to date.
