Answer:
336 cm^2
Step-by-step explanation:
Well theres not exactly a formula, I jsut solve the 3 faces and then double it all since 2 are the same for each except for 1 so the first side is the 10X12 one. that would give you 60 and then you double that and get 120 since 2 same faces.
The next one the 6X13 one is just a sideways rectangle, a=lw and that would be 78. Two faces same side double 78 and get 156.
Now the final side is the bottom which is jsut 10X6. a=lw and that would eqaul 60. No need to double since thats the only side that doesn’t have a duplicate. Add all your result up and you would get
336 cm^2
Answer:
50°
Step-by-step explanation:
Let measure of one equal side be x.
80° +x +x = 180°[ sum of interior angle of triangle is 180°]
= 2x = 180° -80°
= x = 100°/2
=x = 50°
Answer: The Jolene's unit rate in dollars per pound of grain is 0.25.
Explanation:
It is given that the Jolene is making a line graph that represents the price of grain and the number of pound purchase.
The number of pounds are shown on x-axis and the price in dollar are shown on y-axis.
The cost of 1 pound is 0.25, therefore the point (1,0.25) lies on the line.
The cost of 4 pound is 1, therefore the point (4,1) lies on the line.
The unit rate in dollars per pound of grain is the the slope of the line.
The slope of a line is,
Therefore, Jolene's unit rate in dollars per pound of grain is 0.25.
