Lieutenant James made an average of 3 arrests per week for 4 weeks. How many arrests does she need to make in the fifth week to

tankabanditka [31]

Answer:

Step-by-step explanation:

We want the average arrests to be 4. It can be done by calculating the average between the average arrests and arrests during the 5th week, so we get:

Avg(1,2,3,4,5) = (Avg(1,2,3,4) + A(5)) / 2

Where Avg(x) is the average of arrests in given weeks, and A(x) is the number of arrests in a given week.

Solving for A(5) => A(5) = 2*Avg(1,2,3,4,5) - Avg(1,2,3,4) = 2 * 4 - 3 = 8-3 = 5

144,84

304

Step-by-step explanation:

At first, 9) is not correct.

Formula for surface of parallelogram is

A=a*H

DONt divide with 2.

So the 9) is 19.8

10) A=15.1*7=105.7

11) A=14.2*10.2=144.84

12) A=20*15.2=304

5*9=45 right a comparison sentence that represents this equation

lora16 [44]

Suppose that John has a pen that costs $5 and he has 9 similar pens. The total cost of the pens that John has is equal to the cost of his bag. If the cost of the bag is $45, write the verbal model of the situation.

So, cost of each pen = 5

Number of pens = 9

Total cost = 5 * 9

But, it is given that the total cost = cost of the bag and

cost of the bag = 45

So, total cost = 45 and

5 * 9 = 45.
