Answer:
Nirmala can use the lamp for 31.66 hours before it runs out of oil.
Step-by-step explanation:
From the graph,
Take any two points, let say
(15, 25)
(25, 10)
The equation of line in slope-intercept form
Putting and any point, let say (25, 10), to find the y-intercept 'b'
So the equation of line will be:
In order to find how long Nirmala can use the lamp before it runs out of oil, we need to find x-intercept which can be obtained by putting y = 0, and solve for x, as duration lies on x-axis.
so
Putting y = 0
Therefore, Nirmala can use the lamp for 31.66 hours before it runs out of oil.
Answer:
a. The correct answer is 18 regular pancakes, 36 chocolate chip pancakes, 9 blueberry pancakes and 27 sausages.
b. The family ate 32 chocolate chip pancakes, 13 regular pancakes, 8 blueberry pancakes and the 27 sausages.
Step-by-step explanation:
We start to determine the number of regular pancakes to start doing the multiplications, if we have 18 regular pancakes, and she made double chocolate chip pancakes that means she made 36 chocolate chips pancakes, half of the regular so she made 9 blueberry pancakes, and the triple quantity of sausages as she made of blueberry pancakes, so she made 27 sausages, which total is 90 items.
To answer question b. you just need to subtract the items left to the items prepare of each breakfast.
If she works 48 hours per week and she earns 16 dollars per hour, we can find the weekly wage by multiplying 48 by 16. This gets us a weekly wage of $768 (Choice A).
:)
Answer:
15% of $68 is $10.2
$68 + $10.2 = $78.2
The retail price is $78.20
Henry needs to sale 14 rings for his revenue to equal his expenses.
Step-by-step explanation:
Given,
Selling price of ring = $8
Expense on one ring = $1.50
Cost of supplies = $91
Let,
x represent the number of rings.
Expenses = 91+1.50x
Revenue = 8x
Equal expenses means;
Revenue = Expenses
Dividing both sides by 6.5
Henry needs to sale 14 rings for his revenue to equal his expenses.
