Answer:
Step 1) She should have added 25 to each side
Step-by-step explanation:
Since there is a -25 in the original equation, to properly cancel it out, she should have added it to both side, not subtracted. This would ensure that the -25 on the left of the = is cancelled out.
Answer:
20
Step-by-step explanation:
y=20+2.8 and got 100%
Answer:
134.0 in^3
Step-by-step explanation:
Volume = (radius^2 * pi * height)/3 = (4^2 * pi * 8)/3 = 134.0 in^3
2y+20=100
2y=80
y=40
The explanation for this would because because the two base angles of an isosceles triangle are equal so since the both equal to 40 degrees, in total would be 80 degrees.
Since the total degrees of a triangle is 180 and you know the base angles make up for 80 percent you subtract that from the total of the angle your trying to find, which is 2y+20.
