Answer: Isosceles
<u>Step-by-step explanation:</u>
Given: AB || DE , BC is a transversal
∠ABC ≅ ∠BCE by Alternate Interior Angles Theorem --> ∠BCE = 80°
∠DCA, ∠ACB, & ∠BCA are supplementary --> ∠ACB = 50°
By the Triangle Sum Theorem, ∠A+∠B+∠C = 180° --> ∠CAB = 50°
Triangle is isosceles because ∠A ≅ ∠C
Divide the figure into two rectangles:
12*3 (top) + 6*6 (bottom) = 72 yd^2
Answer:
(a/b)^3 times 2/(b^4)
or
2(a/b)^3times 1/(b^4)
or instead of 1/b^4 ------>b^-4
Step-by-step explanation:
you can write equivalent fractions by simply multiplying or dividing both the numerator and the denominator by the same number. i hope that helped.
Answer:
18 gallons of paint could paint 10 classrooms.
Step-by-step explanation:
Given that the school bought 18 gallons of paint, and that each classroom requires 1 4/5 of paint to be painted, to determine how many classrooms can be painted with that amount of paint, the following calculation must be performed:
4/5 = 0.8
1 + 0.8 = 1.8
18 / 1.8 = 10
Therefore, 18 gallons of paint could paint 10 classrooms.
