Brad scored 87, 71, 72, 74 and 86 on his five tests during the semester. The average of those scores count for two thirds of his final grade. He has a final exam at the end of the semester that will count for the other one-third. To get a B. his final grade must be greater than or equal to 80 and less than 90 Solve for the range of grades x that he could score on his final exam that would result in him getting a B. Give your answer as an inequality Assume that 100 is the greatest possible grade .

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24

its very big question plz make it small

18 units²

step-by-step explanation:

first let's find altitude bd using the distance formula

d = √((y₂ - y₁)² + (x₂ - x₁)²)

bd = √((0 - -3)² + (0 - 3)²)

bd = √18

given the placement of points a and c, we can denote that point d bisects segment ac.

we will call ac the base.

using the distance formula

ac = √((0 - 6)² + (-6 - 0)²)

ac = √72

knowing our base and our height, we can plug these into our triangle area formula

area = (b * h)/2

area = (√18 * √72) / 2

area = (√1296) / 2

area = 36 / 2

area = 18 units²
