The answer is C! Annuity means "a fixed sum of money paid to someone each year", which is similar to what the letter C is suggesting.
Answer: 40°
<u>Step-by-step explanation:</u>
There are 4 pink angles (labeled as "a") and each are the same measure.
There are 4 green angles (labeled as "b") and each measure 50°.
A circle is 360°
4a + 4b = 360
4a + 4(50) = 360
4a + 200 = 360
4a = 160
a = 40
Answer:
Car B = 43 miles per gallon
Car A = 43+4=47 miles per gallons
Step-by-step explanation:
Let the mileage of Car B be x miles per gallon
Hence the mileage of Car A will be x+4 miles per gallon
Distance traveled by each car in 1 gallon
Car A = x+4
Car B = x
Total Distance covered by both car in 1 gallon = x+(x+4) which is given as 90 miles
Hence x+(x+4)=90
2x+4=90
2x=86
dividing both sides by 2 we get
x=43
Mileage of Car B = 43 miles per gallon
Mileage of Car A = 43+4=47 miles per gallons
1 the equation is y=x+3 and yes y is directly proportional to x
2 the answer is c
3 the answer is c
4 the answer is b
