The area of a triangular block is 64 square inches. If the base of the triangle is twice the height, how long are the base and height of the triangle?

Answers

Answer:

Area of the triangle(A) is given by:

A = (1)/(2)bh             ....[1]

where,

b is the base and h is the height of the triangle.

As per the statement:

The area of a triangular block is 64 square inches.

A= 64 in^2

It is given that:  If the base of the triangle is twice the height

b = 2h          .....[2]

Substitute these in [1] we have;

64 = (1)/(2) \cdot (2h) \cdot h

64 = h^2

or

h^2 = 64

h = √(64) = 8 inches.

Substitute h =8 in [2] we have;

b = 2(8) = 16 in.

therefore, the base and height of the triangle are:  16 inches and 8 inches.

Answers

Answer:

B) x+y=120; 12x+20y=1720

Step-by-step explanation:

If variables are defined as ...

x = number of student tickets sold

y = number of adult tickets sold

then the problem statement can be modeled by ...

x + y = 120 . . . . . . the total number of tickets sold is 120

12x + 20y = 1720 . . . . . the total collected from ticket sales was $1720

___

Total revenue is the sum of the revenues from sales of each ticket type. The revenue from a given ticket type is the product of that ticket price and the number sold.

What is 1/8 divided by 1/2

Answers

Solve using the KCF Method (Keep, Change, Flip)

1/8 / 1/2
1/8 stays the same
= 1/8 x 1/2
Change the division sign into multiplication
= 1/8 x 2/1
Flip 1/2 so it can be 2/1
= 2/8 
Multiply as you would. (Numerator x Numerator, Denominator x Denominator)
= 1/4
Simplified
the answer would be 2\8 but you have to divide them by 2 and get 1\4 hope this helps
