Step-by-step explanation:
Multiplying decimals is not as hard as you think :)
Example 1:
Multiply: 5.2 x 4.5
Step #1: Line up the decimals
Step #2: Multiply like you usually would when multiplying two numbers.
Step #3: Move your decimal twice to the left to get 23.40
Work:
5.2
<u>x 4.5</u>
260
<u>+ 2080</u>
23.40 (I moved the decimal twice to the left from the zero)
Answer:
11 yd
Step-by-step explanation:
16-5=11 yd
Answer:
y = m/3
Step-by-step explanation:
y 1
---- = --------
m 3
Cross multiply
3*y = 1*m
3y = m
Divide each side by 3
3y/3 = m/3
y = m/3
To convert a pexent to a decimal you have to multiply by 100.
Move the decimal: Another way to convert from decimal to percentage format is to move the decimal two places to the right.
Hope this helped :)
Have a good day
Step-by-step explanation:
Use SOH-CAH-TOA.
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
You're given an angle, the adjacent side to that angle, and the hypotenuse. So use cosine.
Cosine = Adjacent / Hypotenuse
cos 37° = 48 / x
Multiply both sides by x.
x cos 37° = 48
Divide both sides by cos 37°.
x = 48 / cos 37°
If desired, use a calculator to evaluate.
x ≈ 60.1
