Answer:
x=−0.35
Step-by-step explanation:
2.5x−10.5=64×0.5x
2.5x−10.5=32x
−10.5=32x−2.5x
−10.5=29.5x
− 29.5/10.5=x
−0.355932=x
Answer:
A.) A= 20h+100 B= 40h
B.) 3hours - Company A(cost more) 5 hours- Both cost the same amount 10 hours- Company B (cost more)
C.) 6 hours
Step-by-step explanation:
B. because if u add 2.5 and 3 together it's 5.5 then times 4 because the fraction
Answer:
x+x=8
that's mean: 2.x/4 + 4.x/1 = 18/1
we find at least a common multiple of 4 and multiply the units by 4
2x + 16x = 72
18x = 72/:18
x = 4
263.27 m^2
rectangle : 15 x 10 = 150 m^2
the half circle at the top has a diameter of 6m. therefore, it’s radius is 3m. if it is cut in half, the part removed from the triangle height is 3m. therefore, the height of the triangle is 35 -15 = 20; 20 - 3 = 17. the height of the triangle is 17. the triangle area formula is a = 1/2(bh).
a = 1/2 (10)(17)
a = 1/2 (170)
a = 85 m^2
the circle would be a = πr^2 but divided by 2 bc it’s a half circle
a = π(3)^2
a = π9
a = 28.27 m^2
150 + 85 + 28.27 = 263.27 m^2
