Q3. Given that y is directly proportional to x and that y= 40 when x= 200, find the value of
(a) y when x= 15
(b) x when y= 8
Q4. If y is inversely proportional to x and that y= 8 when x= 30, find the value of:
(a) the value of y when x= 4
(b) the value of x when y= 360
Answers
Answer:
Q2)
We have food for 400 people, and it will last for 23 days.
Then we have an inverse relation, where the number of days decreases as the number of people increases, this means that we have a relationship like:
23 days = K/400 people.
Then we get:
(23 days)*(400 people) = K = 9200 days*people.
Now if we increase the number of people by 60, we get.
people = 460
Then the number of days that this will last is:
D = (9200 days*people)/460 people = 20 days.
The food will last for 20 days.
Q3) We have a proportional relationship (y = k*x) such that y = 40 when x = 200, then we get:
40 = k*200
With this, we can find the value of k
40/200 = k = 0.2
Then the proportional relationship is:
y = 0.2*x
a) We need to replace x by 15.
y = 0.2*15 = 3
y = 3
b) We need to replace y by 8.
8 = 0.2*x
8/0.2 = x = 40
x = 40
Q3) y is inversely proportional to x (y = k/x), and y = 8 when x = 30.
Then we get:
8 = k/30
Then the value of k is:
8*30 = k = 240
then the relationship is:
y = 240/x
a) we need to replace x by 4
y = 240/4 = 60
y = 60
b) we need to replace y by 360
360 = 240/x
360*x = 240
x = 240/360 = 0.666...
x = 0.666...

Roger jarred 15 liters of jam after 2 days. How much jam did Roger jar if he spent 6 days making jam?
Answers
Answer: 45 liters
Step-by-step explanation:
If Roger jars 15 liters of jam in 2 days, we can divide to see how much liters of jam Roger can jar in 1 day. We can divide 15 by 2 to find how much jam can be jarred in one day.
15 / 2 = 7.5.
Roger can jar 7.5 liters of jam every day.
Now we can multiply 7.5 by 6 to find how much jam Roger can jar at the end of 6 days.
7.5 x 6 = 45.
Therefore, Roger can jar 45 liters of jam in 6 days.

What is the volume of a cube with an edge length
of 2/3 foot?
Answers
Answer:
V= 512 inches or, 42.67 feet
Step-by-step explanation:
So a cube has the same length on all sides so you would multiply length times with times area or V = a^3
So, 2/3 foot is equal to 8 inches so you would do V = 8^3 which would get you the answer,

The Patel family looks at map to plan their family vacation. They plan to travel from Smithville to Jonesville, which are 3 3/4 inches apart on the map. Then they plan to travel from Jonesville to Clarksville, which are 5 1/4 inches apart on the map. The scale on the map is 1/2 inch equals 4 miles. What is the actual distance the Patel family will travel by the time they reach Clarksville? Enter your answer in the box
Answers
Answer: 72 miles
Step-by-step explanation:
The total distance from Smithville to Clarksville will be:
= 3 3/4 + 5 1/4
= 9 inches
Since the scale on the map is:
1/2 inch = 4 miles
1 inch = 4 × 2 = 8 miles
Therefore, 9 inches will be:
= 9 × 8 = 72 miles
The actual distance that the Patel family will travel by the time they reach Clarksville will be 72 miles.

40%x+15=x rewritten as:
.4x+15=x Subtract .4x from both sides will give us:
15=.6x Now divide each side by .6 to be:

What is the answer to -3/7 ÷ 3/8 in simplest form?
Answers
Explanation: Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator and changing the operation to multiplication. Then the equation becomes. This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 24 and 21 using 24÷321÷3=8/7. The fraction is the same as 8÷7. Therefore: 3/7÷3/8=1 1/7
