Answer:
Area = 23.12 cm²
perimeter = 24.28 cm
Step-by-step explanation:
top shaded region is circular arc with 90° sector angle
so perimeter of arc is 90 / 360 * 2πr
here radius of arc is half the length of square side
r = 6.8/2 = 3.4
top area shaded perimeter = 90/360 * 2 * 3.14 * 3.4
= 1/4 * 2 * 3.14 * 3.4
= 5.338
bottom region perimeter is also same
total perimeter of shaded region is = side + side + two arcs
= 6.8 + 6.8 + 2 * 5.338
= 13.6 + 10.676
= 24.276
= 24.28
Area of top shaded region is 90/360 * πr²
A = 1/4 * 3.14 * 3.4²
= 9.0746
bottom shaded region area is half of area of square - area of bottom arc
= 6.8 * 3.4 - 9.0746
= 23.12 - 9.0746
= 14.0454
so total area of shaded region is 9.0746 + 14.0454
= 23.12
or you can just calculate area as half of area of total square = 6.8² / 2
= 23.12

#Carry on LearningFrank is going to buy some ties
at $7.50 per tie and some shirts
at $18.50 per shirt. If he buys
twice as many ties as shirts and
spends no more than $205, what is the greatest number of shirts he
can buy? [All prices include tax.]
Answers
Answer:
6 shirts
Step-by-step explanation:
The cost of a shirt and 2 ties is ...
$18.50 +2(7.50) = $33.50
For $205, Frank can buy $205/$33.50 = 6.12 sets of shirt and ties.
Frank can buy 6 shirts (and 12 ties) for an amount less than $205.

Henry is investing at a continuously compounded annual interest rate of 4.4%. How many years will it take for the balance to triple? Round your answer up to the nearest whole number, and do not include units in your answer.
Answers
The number of years it would take the amount to triple is 25 years.
The formula that would be used to determine the number of years it would take the balance to triple is:
FV = PV x [tex]e^{r}[/tex]N
Where:
n = number of years fv = future value PV = present value e = 2.7182818 r = interest rate3 = [tex]e^{0.044}[/tex]N
Take the log of both sides
log(3) / log(e) / (0.044) = 25 years

Jon paid $40 for a shirt, but later that week the

Answers
Answer:
15% of 40 is 6
9514 1404 393
Answer:
$6
Step-by-step explanation:
15% is the ratio of the price increase to the original price.
As a fraction 15% = 15/100 (fifteen hundredths).
As a decimal, 15% = 0.15 (fifteen hundredths).
__
The statement about the price increase is telling you ...
(increase)/(original) = 0.15
Multiplying by the original price, we get ...
(increase) = 0.15×(original) = 0.15 × $40 = $6.00
The price of the shirt went up $6.00.
