Answer:
Sales tax = $2.79
Step-by-step explanation:
(18 x 48.6)
/100
= 8.748 = $8.75 tip amount total
48.60-8.748 = 39.852 sales total
(39.852 x 7)/100
= 2.78964 = $2.79 sales tax
39.852 - 2.78964 = 37.06236 = $37.06 cost of bill
Sales tax was asked = $2.79
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:
where k is the proportional constant
To calculate the value of k, plug in the values of x and y:
x=7
y=4
Now, write down the relation between x and y:
"</span><span>how long would it have taken 3 electricians to have done the job?"
x=3
Let's find out y:
So it would take 9 hours and 20 minutes to have this job done.

Answer:
C. 28.6, 0.28
Step-by-step explanation:
<em><u>To find the white portion's area, you add 44 and 47, then multiply it by π</u></em>:
44 + 47 = 91
(3.14)
A = 28.574 → A = 28.6
<em><u>There are 7 parts of the circle, and 2 of them are white. So divide 2 by 7:</u></em>
2 ÷ 7 = 0.28
1/4 of an hour
68 miles per hour
multiply 68 by 1/4 = 68/1 *1/4 = 68/4
divide 68 by 4
68/4 =17
it can swim 17 miles
