Answer: He earns $169 after 13 hours
Step-by-step explanation:
To solve this we need to find out how much he earns per hour.
This can be identified using simply division.
130/10=13
He earns $13 per hour.
Now we multiply 13*13=169
He earns $169 after 13 hours
The answer is 4
you just subtract 3 from 7
Answer:
3h² + 35hw ;
a = 3 ; b = 2 ; c = 35
Step-by-step explanation:
Given that :
Dimension of bookcase :
Height = h ; Length = 2h ; width = w
Area of backside :
Height * length
h * 2h = 2h²
Cos of back material = $1.5 per ft²
Cost = 1.5 * 2h²
Cost = 3h²
Top and bottom :
Length * width
2h * w
Side area = 3 * h * w
Total area : Top + bottom +. Side
Total area : 2hw + 2hw + 3hw = 7hw
Pine = $5 per sq foot
Total cost = $5 * 7hw
= $35hw
Entire cost, C
3h² + 35hw
From the format :
ah^b + chw,
a = 3 ; b = 2 ; c = 35
Answer:
Step-by-step explanation:
Given AB with coordinates A(3, -3) and B(1, -1)
Perpendicular bisector passes through midpoint of the segment.
<u>Midpoint of AB has coordinates:</u>
- x = (3 + 1)/2 = 2, y = (-3 - 1)/2 = -2
<u>Slope of AB</u>
- m = (-1 + 3)/(1 - 3) = 2/-2 = -1
<u>Slope of the perpendicular line is:</u>
<u>The equation of the line in point-slope form:</u>
- y - y₁ = m(x - x₁), where m = 1, x₁ = 2, y₁ = -2
- y - (-2) = 1(x - 2) ⇒ y + 2 = x - 2
<u>Converted into slope-intercept form:</u>
