Step-by-step explanation:formula for area of triangle = base x height x 1/2
8x10 = 80 80 / 2 = 40 40 x 4 = 160 area for square =base x height
the pyramid is comprised of four triangles and one square, all we need is to find the individual surface areas of the shapes that compose the pyramid
(x, y) is the ordered pair or the point of the line. The given problem is an example of a linear graph and its ordered pair represents (amount, number of gallons).
(3.75, 1) is one of the ordered pairs of the graph since $3.75 is the amount that you paid in 1 gallon of gas.
Moreover, $12 is the amount that Berto paid for the gas, we will divide it to $3.75 per gallon in order to get the number of gallon that is put in his car.
Solution: $12 / $ 3.75 per gallon= 3.2 gallons.
Therefore, another ordered pair on the graph of the line relating number of gallons of gas is (12, 3.2) since $12 is the amount that you paid for 3.2 gallons of gas.
Answer:
1.65
Step-by-step explanation:
100 pounds of the mixture = 1.36 * 100 = 136 dollars.
She uses 20 pounds of jelly beans that cost
20 * .20 = 4.00
136 - 4 = 132 dollars left for 80 pounds of sugar candies.
80 pounds = 132 pounds of sugar candies.
1 pound = x
80/1 = 132 / x Cross multiply
80x = 132
x = 132 / 80
x = 1.65 / per pound
