a. 5/9 or 11/18
b. 3/8 or 4/9
Answer:
for a it would be 11/18 and for b it would be 4/9
Step-by-step explanation:
This is because I did the same butterfly method. 5 times 5 times 18 which is 90 for 5/9 and 9 times 18 is 99 for 11/18, you can also write it as 5/9 and 11/18 but cross multiply. This is also what I did with the second one.
A hot air balloon descends from an altitude of 2,000 feet at a constant rate of 90 feet per minute. Write a linear function in terms of y=mx+b to model the situation.

Step-by-step explanation:
rate of change when the coordinates are (2,11) and (5,17)? :/
Answer:
make a x and y chart
so x should have 2 and 5 while y has 11 and 17
2 to 5 is plus 3 while 11 to 17 is 6
now do you divided by x
6 divided by 3 equals 2
slope / rate of change is 2

witch is bigger
1/4
or
2/7
Answer:
2/7

Which two quantities are in a proportional relationship, and why?
Answer:
[tex]\frac{3}{4} =\frac{18}{24}[/tex] The ratios are the same .
Step-by-step explanation:
When y ∝ x then,
[tex]y=k*x[/tex]
When y ∝ 1/x then
[tex]y=\frac{k}{x}[/tex]
while k is a constant.
Answer:
3/4 and 18/24; the ratios are the same.
Step-by-step explanation:
A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d. The following proportion is read as "three is to four as eighteen is to twenty-four."
In problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. To find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
Here, 3 and 24 are the extremes, and 4 and 18 are the means. Since the cross products are both equal to 60, we know that these ratios are equal and that this is a true proportion.
