Answer:
18 dollars and 50 cents + s = 30 dollars
s minus 18 dollars and 50 cents = 30 dollars
Step-by-step explanation:
how much more of 18.50 to get to 30
30-18.50=11.50
s=11.50
Answer:
21 pints
Step-by-step explanation:
In the paint, the ratio of yellow to blue is 7:3
7:3
x : 9
To find maintain the equivalent ratio and find x, we multiplied both sides of 7:3 by 3
21 : 9
The answer should be 21 pints
Hope this helps :)
Have an awesome day!
Answer:
z = 1.5
Step-by-step explanation:
x - mean
standard score = -----------------
6
Substituting 74 for x, 65 for mean, we get:
74 - 65
standard score = ----------------- = 9/6 = 1.5
6
The pertinent z-score (standard score) is 1.5.
First, find the total inflation over the past 37 years: 37 years * 3.7%/year = 136.9 %. Then just multiply the original cost by the inflation and add the original cost so: ($20,000 * 1.369) + $20,000 = $47,380.
Given:
The first four numbers in a pattern are 4, 2, 1, and 0.5.
To find:
The next three numbers in the pattern.
Solution:
We have a pattern,
4, 2, 1, 0.5
Clearly, it is a GP and the common ratio is
because each term is half of its preceding term.
Next term after 0.5 = ![0.5\times \dfrac{1}{2}=0.25](https://tex.z-dn.net/?f=0.5%5Ctimes%20%5Cdfrac%7B1%7D%7B2%7D%3D0.25)
Next term after 0.25 = ![0.25\times \dfrac{1}{2}=0.125](https://tex.z-dn.net/?f=0.25%5Ctimes%20%5Cdfrac%7B1%7D%7B2%7D%3D0.125)
Next term after 0.125 = ![0.125\times \dfrac{1}{2}=0.0625](https://tex.z-dn.net/?f=0.125%5Ctimes%20%5Cdfrac%7B1%7D%7B2%7D%3D0.0625)
Therefore, the next three numbers in the pattern are 0.25, 0.125 and 0.0625 respectively.
