1 : 1.71 : 2.43
Step-by-step explanation:
What divided by 7= 1?
7/7 = 1
So use that answer for the other two dolls.
12/7 = 1.71
17/7 = 2.43
1 : 1.71 : 2.43
Have the same ratio as
7 : 12 : 17
Given cost function C(a) = 7.5a, where a is the number of T-shirts.
Let us complete table.
We need to plug a=1,2,3,4 in above function to get the costs to complete the table.
For a =1
C(1)= 7.5(1) = 7.50
For a =2
C(2)= 7.5(2) = 15.00
For a =3
C(3)= 7.5(3) = 22.50
For a = 4
C(4)= 7.5(1) = 30.00
In order to find the common difference we need to find the diffrences of costs 15-7.50 = 7.50
22.50-15.00=7.50.
<h3>Therefore, common difference is 7.5.</h3>
a represents the number of T-shirts.
Domain of a is the numbers we can take for a.
So, we can take value for a as 0 or greater value.
Therefore, domain for a would be a is gerater than or equal to 0.
<h3>Domain : a≥0</h3>
13,000,000 rounded to the nearest tenth is 18,000,000
Answer:
$71.88
Step-by-step explanation:
subtract 20 percent from 29.95
20 of 29.95 is 5.99
29.95 - 5.99 = 23.96
3 ink cartridges are needed so
23.96 × 3 = 71.88
Answer:
Solving for x, we could simply say
3x-4=2%28y-2%29-->3x=2%28y-2%29%2B4-->x=%282%28y-2%29%2B4%29%2F3 or x=2%28y-2%29%2F3%2B4%2F3 .
Not wrong, but that could be "simplified" further, and we may need to do that before dividing by y .
It may be better to get rid of those brackets from the start:
3x-4=2%28y-2%29-->3x-4=2y-4-->3x=2y-->x=2y%2F3<-->x=%282%2F3%29y .
Now,
x%2Fy=%282%2F3%29y%2Fy --> highlight%28x%2Fy=2%2F3%29 , for y%3C%3E0
(which in the case of 3x-4=2%28y-2%29 is equivalent to x%3C%3E0 ).
