The first thing to do is turn this into an equation:
2/3 ÷ 10
10 as a fraction is 10/1
2/3 ÷ 10/1 =
Fractional division is just fractional multiplication after switching the numerator and the denominator of the second fraction:
2/3 X 10/1
Fractional multiplication is simply multiplying the numerators by each other, and the denominators by each other:
2 X 10 = 20
3 X 1 = 3
20/3
Each piece of liquorice will be 20/3 or 6 2/3 of a yard long.
Answer:
the answer is 4x-7
Step-by-step explanation:
hope this helps!
.8 (88%)+.2x=90%
70.4%+.2x=90%
subtract 70.4% from 90% to get 19.6%
make the .2x into 2 and the 19.6 into 196
divide 196 by 2 to come up with the answer of 98%.
you will need a 98% to have a 90% for the final grade
The altitude of an equilateral triangle is 15.
In order for us to get the area of the equilateral triangle, we need to find the formula first.
Area = square root of (3) / 4 * a^2
Area = square root of (3) / 4 * 15^2
Area = 97.42786 square units.
<span>So the area of the equilateral triangle given the altitude 15 is 97.43 square units.</span>
