Answer:
2x-15
Step-by-step explanation:
Sara has x dollars
dina has 15 less which is
x-15
together it will be
x+x-15
=2x-15
It would equal 0.45
Step-by-step explanation:
9 × 5 = 45 put a decimal in front of the 45
Answer:
32 ft^2
Step-by-step explanation:
Area of a trapezoid: (b1 + b2 /2 )h
a= (3+5/2)2
8/2= 4
4*2= 8
8 is the area of a trapezoid, to find area of 4 trapezoid multiply by 4
4*8= 32ft
Answer:
y = 2/3x + 3 2/3
Step-by-step explanation:
slope intercept form: y = mx + b
isolate the y => y = 2/3(x - 2) + 5 => y = 2/3x - 4/3 + 5 => y = 2/3x + 3 2/3
Answer:
2 seconds
Step-by-step explanation:
This means the height, and thus h(t), is equal to zero.
0=-16t^2 + 16t + 32
0= t^2 - t - 2 (divide both sides by -16)
0 = (t-2)(t+1) [factor]
t = -1, 2 [set each factor equal to zero]
But as time cannot negative, take t=2, giving us 2 seconds.
