Answer:
$48
Step-by-step explanation:
To start off, we know that Avery put 20% of the $80 in her bank account. We can figure out how much 20% of 80 is by multiplying 80 by 20% and then subtracting that number from 80. Remember to switch 20% to its decimal form (20% -> .2).
Step 1) 80 x .2 = 16
Step 2) 80 - 16 = 64
Next, we have to figure out how much 1/4 of the remaining $64 would be. We just simply divide 64 by 4 to figure out how much Avery spent.
Step 3) 64 / 4 = 16
Lastly, since we know Avery spent 16 dollars, we can subtract the 16 from 64 to get our final answer.
Step 4) 64 - 16 = 48
<h3>
Answer: Choice B) 468 cm^2</h3>
============================================================
Explanation:
As the diagram shows, we have a triangular face with a base of b = 18 and height of h = 13. The area of this triangular face is:
A = 0.5*b*h
A = 0.5*18*13
A = 117 square cm or cm^2
This represents the area of one face, but there are 4 identical copies of this triangular face assuming this tetrahedron is a regular polyhedron. So we have a total surface area of 4*117 = 468 cm^2 which points us to choice B
This is the amount of paint you'll need to cover the outer surface of the pyramid, or you can think of it as the amount of wrapping paper needed. This assumes there are no gaps or overlaps.
<h2>
Answer: ( 2 , -2 )</h2>
Step-by-step explanation:
Mid-point = [ ((x₁ + x₂) ÷ 2) , ((y₁ + y₂) ÷ 2) ]
= [ (6 + (-2)) ÷ 2] , [(1 + (-5)) ÷ 2]
= ( 2 , -2 )
He can either download both the pedometer and the math apps,
or he can download only the photo app and no more.
Pedometer + math = 0.54 GB. Fits in 0.64 GB.
Photo = 0.403 GB. Fits in 0.64 GB, but only 0.237 GB left.
Not enough for pedometer (0.24)
or math (0.3) .
