Answer:
After 5 months
Step-by-step explanation:
Step one:
given data
LA Fitness charges a registration fee of $75 plus $35.75 per month for members
let the number of months be x
and the total charges be y
total is
y= 75+35.75x----------1
Gold's Gym charges a registration fee of $164 plus $17.95 for members
let the number of months be x
and the total charges be y
total is
y= 164+17.95x----------2
Step two:
equate 1 and 2
75+35.75x= 164+17.95x
solve for x
35.75x-17.95x=164-75
17.8x=89
divide both sides by 17.8
x=89/17.8
x=5 months
Alright so I'm coming up with this on the fly; you have the first six letters (a,b,c,d,e,f) and 0-9 and your ten numbers. calculate the amount of possible combinations for the letters by simply writing them down.
ab, ac, ad, ae, a f- five
bc, bd , be, bf- four
cd, ce, cf- three
de, df- two
ef,- one.
adding these all together gets a total of 15 for the letters. now the numbers
01, 02, 03, 04, 05, 06, 07, 08, 09- nine
12, 13, 14, 15, 16, 17, 18, 19- eight
23, 24, 25, 26, 27, 28, 29- seven
34, 35, 36, 37, 38, 39- six
45, 46, 47, 48, 49- five
56, 57, 58, 59- four
67, 68, 69- three
78, 79- two
89- one
added together with a total of 45 combinations.
alright so, 45 different number combinations and 15 letter combinations. multiplying 15 by 45 should tell you the total possible combinations for a two letter and two number serial-number
Answer:
A: a^3
B: c^1 or just c
Step-by-step explanation:
Subtract the exponents
To answer this question you will find out the total number of cupcakes donated and then calculate the amount of each flavor based on the percentage that is stated.
Here are the steps:
1. 12 x 10 x 12 (12 classes each donating 10 dozen) = 1440
2. 0.55 x 1440 (55% are chocolate) = 792 chocolate
3. 1440 - 792 (the remaining number of cupcakes)=648
4. 1/3(33 1/3%) x 648 = 216 red velvet
5. 1440 - 792 (chocolate) - 216 (red velvet) = 432 vanilla cupcakes
Chocolate-792
Red velvet - 216
Vanilla - 432
