Answer:

Step-by-step explanation:

so the steps to doing this are as follows :

Subtract the accepted value from the experimental value.

Take the absolute value of step 1.

Divide that answer by the accepted value.

Multiply that answer by 100 and add the % symbol to express the answer as a percentage.

|18.7-19.3|/19.3 = 0.031088 * 100% = 3.1%

perimeter is the distance around the outside of the object or P = 2L + 2W

2(3w) + 2w = 24

6w + 2w= 24

8w = 24

w= 3

3w= 9

Width is 3in. and length is 9in.

The time required to complete a job varies inversely as the number of people working. it took 4 hours for 7 electricians to wire
Solnce55 [7]
Let's assign variables

The time required to <span>wire a building: y
</span>
The number of electricians <span>to have done this job: x

</span>
<span>y varies inversely as x

so that:
y= k\frac{1}{x}
where  k is the proportional constant


To calculate the value of k, plug in the values of x and y:
x=7
y=4

4=k (\frac{1}{7}) \\~\\k=28


Now, write down the relation between x and y:
y=28x


"</span><span>how long would it have taken 3 electricians to have done the job?"
x=3
Let's find out y:
y=(28) \frac{1}{3} = \frac{28}{3} =9 \frac{1}{3} =9.333333~~hr

So it would take 9 hours and 20 minutes to have this job done.

skad [1K]

Answer:

Both brothers will have the same amount of money is their saving accounts after six months.

Step-by-step explanation:

I worked this out by finding out the first 8 months of savings for both brothers:

Patrick:               His brother:

200                     150

225                     185

250                     220

275                     253

300                     290

325                     325

375                     360

400                     395

I then looked across my results to see that at 6 months both brothers had $325.

Hope this helped.
