She would pay $4, do you know how to make a proportion?
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:
HI = 15
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= , substitute values
= = 5
Multiply both sides by 3
HI = 15
The expression that we need to get is:
So the correct option is the second one.
<h3>Which expression gives the number of gallons of stain Bradley will need?</h3>
We know that 1 gallon is enough to cover 200 ft².
We have two rectangular areas, one of:
23 feet by 10.4 feet, and other of 10.5 feet by 7.2 feet.
Then the total area is:
A = (23 ft)*(10.4 ft) + (10.5ft)*(7.2 ft)
The number of gallons needed is given by the quotient between the area that we want to cover, and the area that covers one gallon, so the expression is:
So the corerect option is the second one.

30 60 90 right triangle
leg = 6 so other leg = 6√3
A = (1/2)(6+6)( 6√3+ 6√3)
A = 6 (12√3)
A = 72√3
answer is D
72√3
