Answer:
23 sin 55°
x = ------------------ (matches first answer choice)
sin 85°
Step-by-step explanation:
Note that 2 angles and 1 side length are given. This is a typical application of the Law of Sines. The formula for finding the length of side x is:
23 sin 55°
x = ------------------ (matches first answer choice)
sin 85°
Answer:
Initially, Anglea has $6*w in total.
Then she buys N books, at $17 each, then the total cost of the books is: N*$17
After that, she had left $w.
a) This means that:
$6*w - N*$17 = $w
Now we can isolate the variable N in one side of the equation:
N*$17 = $6*w - $w = $5*w
N = ($5/$17)*w
N = (5/17)*w
That is the equation that tells the number of books Angela bought in terms of w.
b) Now we just need to replace the w by 34 in the above equation:
N = (5/17)*34 = 10
If w = 34, Angela bought 10 books.
Answer:
100 centimeters
Step-by-step explanation:
Area of a square is side x side= s x s or s²
If s² = 1 square meter
s = √1 = 1 meter
Each side is 1 meter. To convert to centimeters multiply by 100 since there are 100 centimeters in 1 meter.
Each side is 100 centimeters
9/22
i think i didn't get what you meant by estimate
Answer:
You are multiplying the whole number with the reciprocal of the fraction.
Step-by-step explanation:
To divide a whole number by fraction.
You are taking X which is a whole number over the fraction.
its the same as taking x and multiplying it by the reciprocal of the fraction
So if you have 5 divided by 1/2, it's the same as saying 5 times 2/1.
