Answer:
34 minutes
Step-by-step explanation:
Given
![Time\ Spent = 6](https://tex.z-dn.net/?f=Time%5C%20Spent%20%3D%206)
![Phone\ Calls = 40](https://tex.z-dn.net/?f=Phone%5C%20Calls%20%3D%2040)
Required
Number of minutes left to spend (x)
Since there's only 1 minute left to spend on every other call;
Time left = x * 1
Time left = x
The required can further be calculated using:
![Time\ Spent + Time\ Left = Phone\ Calls](https://tex.z-dn.net/?f=Time%5C%20Spent%20%2B%20Time%5C%20Left%20%3D%20Phone%5C%20Calls)
This gives:
![6 + x = 40](https://tex.z-dn.net/?f=6%20%2B%20x%20%3D%2040)
Subtract 6 from both sides
![x = 40 - 6](https://tex.z-dn.net/?f=x%20%3D%2040%20-%206)
![x = 34](https://tex.z-dn.net/?f=x%20%3D%2034)
<em>Hence, there are 34 minutes left to spend</em>
Answer:
Part a) The raisins cost $0.8 per ounce
Part b) 1.25 ounces
Step-by-step explanation:
<u><em>The correct question is</em></u>
Jackson bought 5 ounces of raisins for $4 dollars.
a) How much do raisins cost per ounce?
b) How many ounces of raisins can be bought for $1?
Part a) How much do raisins cost per ounce?
we know that
To find out the unit rate divide the total cost by the total weight
so
![\frac{4}{5} =\$0.8\ per\ ounce](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B5%7D%20%3D%5C%240.8%5C%20per%5C%20ounce)
therefore
The raisins cost $0.8 per ounce
Part b) How many ounces of raisins can be bought for $1?
we know that
The raisins cost $0.8 per ounce
using proportion
Find out how many ounces of raisins can be bought for $1
Let
x -----> the ounces of raisins
![\frac{1}{0.8}=\frac{x}{1}\\\\x= 1.25\ ounces](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B0.8%7D%3D%5Cfrac%7Bx%7D%7B1%7D%5C%5C%5C%5Cx%3D%201.25%5C%20ounces)
Answer: D
Step-by-step explanation:
1. Subtract 36 to 28.80
2. Divide the answer to the first price (36.00)- 7.5 divided by 36.00 or 36
3. When you calculate and find the answer as a decimal, then make it into a percentage
So if... you divide 7.5 divided by 36, you get the decimal of 0.2, and when you move the decimals two places only, you get your answer of 20%.
Hopefully it helped you!. Have a good day :-).
Answer: x=4
Step-by-step explanation: The line x=0 is basically the y- axis, so any line parallel with that will have the form x=n. From the point (4,3), we know that it intersects with an x-value of 4 and a y- value of 3. Since it is a vertical line, it must be the line x=4, because the line intersects the x-value of 4. The y-value doesn't matter because a vertical line already intersects all y-values.
