Answer:
(-3,2)
Step-by-step explanation:
when reflecting over the y axis all you have to do is flip the signs on the x values so it would be (-3,2)
Answer:
0.125%
Step-by-step explanation:
area of square
10*10=100
area of triangle
(5*5)/2=12.5
=0.125
(0.10 x 12) + 1.00 y = .5 (12 + y)
1.2 + 1.00 y = 6 + .5 y
.5 y = 4.8
y = 9.6 gallons

Answer:
6.66 hours, that is, 6 hours and 40 minutes.
Step-by-step explanation:
If Mike can plow a field in 12 hours, we plows 1/12 of the field each hour.
If Phil can plow a field in 15 hours, we plows 1/15 of the field each hour.
So if they are working together, they can plow (1/12) + (1/15) of the field each hour, that is:
(1/12) + (1/15) = (5 + 4) / 60 = 9 / 60 = 3 / 20 = 1 / 6.66
So if they work together, they can plow the field in 6.66 hours, that is, 6 hours and 40 minutes.
Answer:
x = 90 and y = 43
Step-by-step explanation:
Since AB = AC then the triangle is isosceles and AD is a perpendicular bisector, thus
x = 90
and the base angles are congruent, thus ∠B = ∠C = 47
The sum of the angles in a triangle = 180°
Subtract the sum of the known angles from 180 for value of y
y = 180 - (90 + 47) = 180 - 137 = 43
