1 mi = 5280 ft
1 h = 3600 s
therefore:
![31.8\ \dfrac{mi}{h}=31.8\cdot\dfrac{5280}{3600}\ \dfrac{ft}{s}=46.64\ \dfrac{ft}{s}](https://tex.z-dn.net/?f=31.8%5C%20%5Cdfrac%7Bmi%7D%7Bh%7D%3D31.8%5Ccdot%5Cdfrac%7B5280%7D%7B3600%7D%5C%20%5Cdfrac%7Bft%7D%7Bs%7D%3D46.64%5C%20%5Cdfrac%7Bft%7D%7Bs%7D)
Answer: 31.8 mi/h = 46.64 ft/s
Answer:
43
Step-by-step explanation:
Using the remainder theorem, that is
The remainder on dividing f(x) by (x - h) is the value of f(h)
here division by (x - 3) hence evaluate f(3) for remainder
f(3) = 3² + 14(3) - 8 = 9 + 42 - 8 = 43 ← remainder
Answer:
243 cm^2 + 108 cm^2 = 351 cm^2
Step-by-step explanation:
So, we have a rectangle and two triangles, we know all the sides or angles.
Rectangle: with 9 cm lenght 15cm + 12 cm = 27 cm
Formula: A=wl -> A=9*27 = 243 cm^2
Trianlge: A=ab/2
Angle 90°
Side A 12 cm
Side B 18 cm - 9 cm = 9 cm
A=ab/2=12·9/2=54 cm times 2 (for the opposite side) = 108 cm^2 = 351 cm^2
