Determine which statement that justifies the similarities between ABC and A'B'C'
When ABC is dilated by a scale factor of 3 to form A'B'C', the sides A'B'C are 3 times as large as the sides of ABC.
However, all three angles of both triangles remain the same. This is so, because dilation do not affect angles.
So, a statement that can be used to justify the similarities is: AA ≅ AA
Total surface area:
D.)2940pie ft2 (9236.28)
lateral surface area:
3581.4
1st -you times the answer choices by pie
2nd- you follow the cylinder lateral surface area formula= L= circumference times the height
circumference is : pie time radius squared
3rd- you follow the the total surface area formula= S=2B+ L
B=pie times radius squared
L=lateral surface area
4th- the answer you got for total surface area.
find the answer choice that has your answer.
Answer:
Yes. 30 divided by 10 is 3. Three times is right. Aaron is right
Step-by-step explanation:
Width = w=?
Length = l=(3w+8)cm
Perimeter = p = 128cm
Perimeter of a Rectangle = length + length + width + width
Perimeter of a Rectangle =2 length +2 width
P = 2l +2 w
128=2(3w+8)+2w
128=6w+16+2w
128-16=8w
112=8w
112/8=8w/8
14=w
w=14
Width = w= 14cm
Length = l=(3w+8)=3(14)+8 = 42+8 = 50cm
The formula for finding present value of an ordinary annuity is:
, where P - money to be deposited, i - interest rate, n - number of payments.
So in this case, P = 35000, i = 6 / 100 = 0.06, n = 20.
Now, we have everything needed to determine how much money must be deposited:
So the answer is
$401,447.24.
