Answer:
s = 18 mph
Step-by-step explanation:
At downstream, time is; t = 11/(s+ 4)
At upstream, time is; t = 7/(s - 4)
Since they both are passed in the same time, then ;
11/(s+ 4) = 7/(s - 4)
Cross Multiply to get;
11(s - 4) = 7(s + 4)
11s - 44 = 7s + 28
11s - 7s = 44 + 28
4s = 72
s = 72/4
s = 18

The base of a cone has a radius of 6 centimeters. The cone is 7 centimeters tall. What is the volume of the cone to the nearest tenth
Answer:264cm^3
Step-by-step explanation:
Volume of a cone= 1/3×A×h, where A is base area
Base area=πr^2
=22/7× 6^2
=113.143cm^2
Volume=1/3×113.143cm^2×7cm
=264cm^3

Find the area of the shape shown below. Pls help
Answer:
28
Step-by-step explanation:
Think of the shape being made up of a square on top that is 4 units by 4 units and a trapezoid on the bottom with bases 4 and 2 and height 4.
area = area of rectangle + area of trapezoid
area = LW + (b1 + b2)h/2
area = 4 * 4 + (4 + 2)(4)/2
area = 16 + 12
area = 28
The ratio of the length to the width to the height of an open rectangular tank is 10: 5: 8. The height is 18 feet longer than the width. What is the volume of the tank
Answer:
hi
Step-by-step explanation:
how are you
Answer: A: L: W: H = 10: 5: 8
Step-by-step explanation: The height of the tank is 18 feet longer than the width
H = 8 parts, W = 5 parts => 8 – 5 parts = 18 feet i.e. 3 parts = 18, 1 part = 6 feet
Hence, L = 10 * 6 = 60 feet
W = 5 * 6 = 30 feet
H = 8 * 6 = 48 feet
Volume = 60 * 30 * 48 = 86400 ft³
Surface Area = 2 * (30 * 60 + 48 * 60 + 30 * 48) =12240 ft²

The U.S. Department of Labor reports that the average prices for a dozen eggs in the month of May for the past 11 years are as follows: $1.19, $1.21, $1.50, $1.93, $1.50, $1.52, $1.69, $1.69, $1.87, $2.00, $1.96 Round to the nearest hundredth (cent) if necessary. The mean price of eggs over this 11-year period is The median price of eggs over this 11 -year period is
Answer:
Mean price of eggs = $1.64
Median price of eggs = $1.69
Step-by-step explanation:
Mean is the average of the given data
Mean = sum of data/sample size
Sum of data = 1.19+1.21+1.50+1.93+1.50+1.52+1.69+1.69+1.87+2.00+1.96
Sum of data = $18.06
Sample size = 11
Mean price of eggs =18.06/11
Mean price of eggs = $1.64
Hence the mean price of eggs over this 11-year period is $1.64
Median is the price in the middle after rearrangement
Rearranging the data
1.19, 1.21, 1.50, 1.50, 1.52,) 1.69, (1.69, 1.87, 1.93, 1.96, 2.00
Since 1.69 falls in the middle after rearranging;
Hence the median price of eggs over this 11 -year period is $1.69
