8 0

approximately 5% of the time. In decmial form, it is 0.0516129032. If it is in fraction from, then it is 8/155. To explain, you find the total number of cookies. Then you find the number of peanut butter cookies and put that as the numerator over the total as the denominator. After that, you find the number of cookies left after Jose eats one cookie. That becomes the denominator and then find the amount of chocolate chip cookies ib the bag and put it over that total. Multiply both fractions together to get this answer.

Car A leaves San Diego at noon driving at 60 mph along a route which is 400 miles long to San Francisco. Car B leaves San Franci
lilavasa [31]
Distance = speed x time
Distance travelled by car A when car B started = 60 x 2 = 120 miles
Number of miles remaining at the time car B started = 400 - 120 = 280 miles.

At time of their meeting both cars has travelled a combined distance of 280 miles and has spent the same time.
Let t be the time they travelled together before they meet, then the sum of the distance travelled by car A and car B is 280miles.
60t + 80t = 280
140t = 280
t = 280/140 = 2 hours

After 2 hours car A has travelled a further 60 x 2 = 120 miles and car B has travelled 80 x 2 = 160 miles.

Total distance travelled be car A is 120 + 120 = 240 miles

Midpoint of the journey = 400/2 = 200 miles
Therefre, at the time they met, the were 40 miles from the midpoint and they are close to San Francisco.

Substitute u=\ln x, so that \mathrm du=\dfrac{\mathrm dx}x. The integral is then equivalent to

\displaystyle\int\frac{\mathrm dx}{x\ln^px}=\int\frac{\mathrm du}{u^p}=\begin{cases}\dfrac{u^{p+1}}{p+1}+C&\text{for }p\neq1\\\\\ln|u|+C&\text{for }p=1\end{cases}

Then transforming back to x gives

\displaystyle\int\frac{\mathrm dx}{x\ln^px}=\begin{cases}\dfrac{\ln^{p+1}x}{p+1}+C&\text{for }p\neq1\\\\\ln|\ln x|+C&\text{for }p=1\end{cases}

A restaurant is making a large amount of salad dressing. The recipe calls for 15 ounces of vinegar and 54 ounces of oil. What is
ANTONII [103]
Hey. Let me help you out.

Restaurant makes salad dressings, and the recipe calls for two different ingredients - oil and vinegar. We know the amount of ounces of a certain food item; however, ratio is not set, so there is no way for us to know how much of oil and vinegar to use if we want to make half of the portion, or two (any number, really).

Ratios are set with a ":" sign in the middle, which is a division symbol. We can also set up a fraction; however, ratios are not usually set like in the former example.

In order for us to set a ratio, let's put both numbers we know in this ratio.

15:54

So, now that we know our ratio, our next step is to simplify it. In order for us to simplify it, we need to reduce both numbers by finding a common factor that will work out on either side.

I will be attaching an image alongside my question in order for you to study this material.

The number we will divide both sides will be 3, since it's the greatest common factor of both numbers.

5:18

This is a simplified version of the ratio. It's the lowest in terms of simplification we can get down to, so we can consider this problem answered.

Answer: 5:18 is the ratio of vinegar to oil.
