We know that
[the volume of the stack of books]=[area of each book]*[<span>height of the stack]
</span>area of each book=63 in²
height of the stack=15.75 in
<span>so
</span>[the volume of the stack of books]=[63 in²]*[15.75 in]=992.25 in³<span>
the answer is
</span>D) 992.25 in³
Answer: 136 m
Step-by-step explanation:
For first interval,
Time = 2 hours 40 minutes = ![2+\dfrac{40}{60}\text{ hours}\ [\text{1 hour = 60 minutes}]](https://tex.z-dn.net/?f=2%2B%5Cdfrac%7B40%7D%7B60%7D%5Ctext%7B%20hours%7D%5C%20%5B%5Ctext%7B1%20hour%20%3D%2060%20minutes%7D%5D)
Speed = 18 m/h
Distance = 
[Formula : Distance=Speed x time]
For second interval,
Time = 1 hour 50 minutes = ![1+\dfrac{50}{60}\text{ hours}\ [\text{1 hour = 60 minutes}]](https://tex.z-dn.net/?f=1%2B%5Cdfrac%7B50%7D%7B60%7D%5Ctext%7B%20hours%7D%5C%20%5B%5Ctext%7B1%20hour%20%3D%2060%20minutes%7D%5D)
Speed = 24 m/h
Distance = 
Total distance = 48 m +88 m = 136 m
Hence, he went 136 m.
The answer is 16, half of 32 1/8 x 1/2 = 2/16 divided by 2/2 = 1/8 but since you don't need to simplify only use the denominator of 2/16 or only need to multiply 8 and 2.
Answer:
Step-by-step explanation:
Original price that she paid for the dish washer is £240. She wants to sell it and make a profit of 25%. It means that price at which she would make a profit of 25% is
240 + 25/100 × 240 = 240 + 60 = 300
To determine the price tag of 40% discount and that would still ensure that she makes £300,
Let x represent the price tag in £. It means that a discount of 40% on £x would be 300. A discount of 40% on £x is expressed as
x - (40/100 × x) = x - 0.4x = 0.6x
So 0.6x = 300
x = 300/0.6 = 500
So the price tag will be £500
