Volume is length times width times height so x * 9 * 2.5 = 135 & 135/(9*2.5)=x
the length (x) is 6cm
Some of the writing on the paper is not included. If you can reply with the missing information, I'll do my best to help you :)
Answer:
The equation of the cost is C = 50h + 15
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
- m is the slope of the line ⇒ rate of change
- b is the y-intercept ⇒ constant value
∵ A plumber charges 15 per service call
→ That means there is a fixed amount of 15
∵ b is the constant amount
∴ b = 15
∵ It charges 50 per hour
→ That means, the rate of change is 50
∵ m is the rate of change
∴ m = 50
∵ C is the cost for h hours
→ Replace y by C and x by h in the form of the linear equation above
∴ C = m h + b
→ Substitute the values of m and b in the equation
∵ C = 50h + 15
∴ The equation of the cost is C = 50h + 15
Answer:
17m³
Step-by-step explanation:
==>Given:
Prism with right triangular base with the following dimensions:
Height = 17m
Base area = area of the right triangle = ½×2×1 = 1m²
==>Required:
Volume of prism
==>Solution:
Volume of prism = Base area × height of prism
Volume of prism = 1m² × 17m
Volume = 17m³
Answer:
Step-by-step explanation:
126 mi/h = (126 mi)/(1 h)·(5280 ft)/(1 mi)·(1 h)/(3600 s) = (126·5280/3600) ft/s
126 mi/h = 184.8 ft/s = 924/5 ft/s

In 2 seconds, the parachutist falls ...
(184.8 ft/s)·(2 s) = 369.6 ft
