Answer:
Step-by-step explanation:
a. The diameter of the circle will be 30 cm
So circumference is 3.14 * 30 = 94.2 cm.
b. Required percentage = (94.2) * 100 / (4*30)
= 78.5%.
I think the second oneis gas and the third one is liquid
Answer:
<u>We should add 1.2 fluid ounces of oil </u>
Correct statement and question:
You are really excited to have found a Puch Maxi Moped from the mid Eighties, and the spring weather is making you want to get out and ride it around. It doesn't run on straight gasoline, you have to mix the oil and gas together in a specific ratio of 2.4 fl. oz. of oil for every gallon of gasoline. You have 2 quarts of gas. How much oil should you add?

Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Ratio = 2.4 fl. oz. of oil for every gallon of gasoline
Amount of gas you have = 2 quarts
2. How much oil should you add?
Let's recall that 1 liquid gallon = 4 liquid quarts, therefore:
Ratio = 2.4 fluid ounces of oil for every 4 quarts of gasoline
Replacing the with the real amount of gas we have:
Ratio = 1.2 fluid ounces of oil for every 2 quarts of gasoline )dividing by 2 the oil amount and the gas amount)
<u>We should add 1.2 fluid ounces of oil </u>
Answer:
See the bolded parts below. It corresponds to the blanks we have to fill in for each step.
Step-by-step explanation:
Taking a look at the figure, we see that KL ║ MN, ( which is given, as you can see ) while MJ and NJ act each as a transversal. This is a key point that will help us.
2. For step 2, we see that ∠JKL ≅ ∠JMN, while ∠JLK ≅ ∠JNM. This is true is they are present as corresponding angles, on either transversal. We can fill in this blank with " Corresponding angles. "
3. Therefore, for this 3rd step triangles JKL and JMN will be similar by " angle angle similarity. " After all, ∠JKL ≅ ∠JMN / ∠JLK ≅ ∠JNM.
4. This step can be proved by the " Proportionality of Corresponding Parts in Similar Triangles. " As you can see, the triangles are similar - and hence their parts correspond to one another.
5. I believe you mean step 5 to be " JM = JK + KM and JN = JL + LN. " That being said this is true by the " Partition Postulate, " which states that a whole is composed of it's parts.
6. This step substituted the 5th step into the 4th step. Therefore, it can be stated as " Substitute step 5 ➡ step 4. "
7. And for this last step here you can say " Simplify further. "
Answer:
x = 40
Step-by-step explanation:
50 + 150 + 2x + x + x
200 + 4x
360 - 200 = 160
160 / 4 = 40
x = 40
50 + 80 + 40 + 150 + 40
