Answer:
- 3 packages of cups
- 4 packages of napkins
Step-by-step explanation:
You need at least enough for 60, so any requirement for a partial package means you need to buy another whole package. The "ceiling" function gives the next higher integer for a non-integer value.
cups = ceiling((60 cups)/(24 cups/package)) = ceiling(2.5) packages
= 3 packages
__
napkins = ceiling((60 napkins)/(18 napkins/package))
= ceiling(3 1/3) packages = 4 packages
Answer:
Ravi’s present age will be 5.
Step-by-step explanation:
From the given, Let Ravi’s present age is taken as "a" years.
After 15 years, his age = (a+15) years.
By the given, it is identified that the age of Ravi after 15 years is equal to the 4 times of his present age.
Given,
Then, it has been found that the present age of Ravi is 5 when his age after 15 years will be 4 times of his present age.
I think it is 8 but im not sure srry if rong
B. 90. The perimeter is 30+30+15+15=90
We have points (-3, 4), (-1, 2), (4, -3) and (6,-5)
Let's verify it's a line by calculating the slopes between successive points.
Slope is change in y over change in x.
(2 - 4)/(-1 - -3) = -2/2 = -1
(-3 - 2)/(4 - -1) = -5/5 = -1
(-5 - -3)/(6 - 4) = -2/2 =-1
Yup. We have a line of slope -1 through point (-1, 2)
y - 2 = -1(x - -1)
y = -x - 1 + 2
y = -x + 1
That's the linear equation for the table.
Answer: Linear equation: y = -x + 1 slope = -1
