No, a function is always a relation. A relation may not always a function but the vice versa is true.
It's like the relationship between a rectangle and a square. A rectangle has 4 right angles and 2 sets of congruent sides while a square has 4 right angles and all sides are congruent. Which means that a rectangle is a square, but a square may not always be a rectangle.
Answer:
9. n=-15 , 10. f=6, sorry i can't help you more I am just tired and have to get some rest but i hope this helps
Step-by-step explanation:
9. Eight less than 1/3 a number n is -13
so -13 = 1/3n -8
then
-5 = 1/3n
multiply 3 to each side
-15 = n
10. a number f multiplied by -12.3 is -73.8
so -12.3f= -73.8
divide -12.3 on each side
so f=6
Answer:
220 cents, $2.20
Step-by-step explanation:
Count the amount of QUARTERS there are.
7 quarters.
The next coin in the photo is a dime.
4 dimes.
The next coin in the photo is a penny.
5 pennies.
Quarters are worth 25 cents, dimes are worth 10 cents, and pennies are worth 1 cent.
25(7) + 4(10) + 5(1) = v (the total value)
25 * 7 = 175 cents
4 * 10 = 40 cents
5 * 1 = 5 cents
175 + 40 + 5 = v
175 + 40 = 215 cents
215 + 5 = 220 cents
The value of all of those coins is 220 cents, or $2.20.
90ft by 7ft gives an area of:
90 x 7 = 630 sq ft
1/2 fl oz is needed for each square foot
630 x 1/2 = 315 fl oz required.
