Answer:
x=-4
Step-by-step explanation:
1.A to find the answer, round $5820 to $6000. Then round $28 to $30. Each curtain would cost an estimate of $200.
1.B 5820/28=<span>207.857142857
</span>
AVERAGE between 90 and 100%
means not including 90 and 100% but not including 90 or 100%
average=(sum of values in set)/(how many values in the set)
so
4 exams, so there are 4 values
average=(sum)/4
the sum is the known+unknwon
sum=76+99+86+x
so
90<span><</span>average and average <span><</span>100
or
90<span><</span>average<span><</span>100
lets say average=a
a=sum/number
a=(76+99+86+x)/4
90<(76+99+86+x)/4<100
90<(76+99+86+x)/4 and (76+99+86+x)/4<100
solve each for x and find intersection
90<span><</span>(76+99+86+x)/4
times 4 both sides
360<span><</span>261+x
minus 261 both sides
99<span><</span>x
(76+99+86+x)/4<u><</u>100
times 4 both sides
261+x<u><</u>400
minus 261 both sides
x<u><</u>139
so
99<u><</u>x<u><</u>139
since max score is 100
99<u><</u>x<u><</u>100
interval notaion is
[99,100]
answer is 2nd one

lol, this is the hardest question I've done today.
Answer:
You will be paying $41.30 in total.
Step-by-step explanation:
The cost of the meal is $35 and you want to leave 18% tip on the meal.
We want to find the total amount that will be paid.
First, we have to find 18% of $35 and then, add it to the original bill ($35).
18% of 35 is:
18/100 * 35 = $6.30
The tip is $6.30, therefore, the total amount paid will be:
$35 + $6.30 = $41.30
You will be paying $41.30 in total.
