B) it will cost about the same to keep the movie or to return it; she should keep it.
5 days' worth of late fees would be 5(1.50) = 7.50.
The purchase price is 9.99; 9.99+7.50 = 17.49.
If she gets a cab, she pays around $10 round trip; 10 + 7.50 = 17.50
It is roughly the same price.
1 1 9 . 6 5
1 is the the hundreds place
1 is the tens place
9 is the ones place
6 is the tenths place
5 is the hundredths place
Angle = 68⁰ is an inscribed angles, this angle equal 68⁰,
so it intersect arc = 2*68⁰= 136⁰.
Arc of the whole circle (circumference) =360⁰,and it also =b+104+136.
b+104+136 =360
b=360-(104+136) = 120⁰
Answer A. b=120⁰.
450 divided by 2 is 225. 225-50=175. 225+50=275
John has 275 and Andrew has 175.
In order to get this answer, first you divide the whole number by 2. Then you get the number 225. You then have to subtract 50 from 225 because John gets 50 more than Andrew. Then for John, you have to add 50 to 225. To self-check the answer, here is the formula: 175+275=450. Remember that on these kind of word problems, you first divide the whole. Then subtract and add the number that one person gets more than the other person.
The Reuleaux triangle is shown in the attached figure
we know that
the area of a Reuleaux triangle is equal to
where
r=18.6/2--------> r=9.3 m
so
therefore
the answer is
61 m²
