These situations can be represented by the equations

Downstream: t=11/s+4 Upstream:t=7/s-4,

where t stands for time and s is the speed of the swimmer. What is the speed of the swimmer swimming in still water?

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

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

i say 28 also from my math

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**

17, 18, 13, 15, 12, 11, 35, 18, 14

**Answer: Mean- 17

**Median- 15
