<span>1. Determine which ratio forms a proportion with 9/5 by finding a common multiplier.
9/5 x (6/6) = 54/30
a. 54/30
2. Determine which ratio forms a proportion with 15/8 by using cross products.
</span>60/32 / (4/4) = 15/8<span>
c. 60/32
4. In a survey, 3 out of 10 people names blue as their favorite color. 1 out of 5 named red. If 1,200 people were included in the survey, how many named blue or red as their favorite color?
a. 700 people
5.Solve the proportion using cross products. Round to the nearest hundredth if necessary.
</span>385 miles (1 inch / 15 miles) = 25.67 in
b. 25.67 in
Other leg^ 2 = 20^2 - 12^2
other leg^ 2 = 400-144 = 256
then other leg = √256 = 16
Since we have 2 zeros we can take them off and add them back on when we are done.
5 goes into 45 9 times.
now lets add the two zeros back on
900
5 goes into 4500 900 times
Answer:
I believe the answer is c.) x=4
Step-by-step explanation:
I saw this on a webpage:
The moment we see “x,” we can consider picking numbers. The key here is contemplating how complicated the number should be. Swim with the current – let the question tell you. A quick look at the answer choices reveals that x could be something simple. Ultimately, we’re just dividing this value by 2, 3, 4, 5, or 6.
Keeping this in mind, let’s think about the first line of the question. If there are 3 times as many adults as children, and we’re keeping things simple, we can say that there are 3 adults and 1 child, for a total of 4 people. So, x = 4.
Now, we know that among our 3 adults, there are twice as many women as men. So let’s say there are 2 women and 1 man. Easy enough. In sum, we have 2 women, 1 man, and 1 child at this picnic, and a total of 4 people. The question is how many men are there? There’s just 1! So now we plug x = 4 into the answers and keep going until we find x = 1. Clearly x/4 will work, so C is our answer. The key was to let the question dictate our approach rather than trying to impose an approach on the question.
The fraction of the container that is filled with gasoline is 6/20, which reduces to 3/10.
ANSWER: 3/10
