If a polyhedron has 11 faces and 18 edges, how many vertices does it have?
Answers
Use Euler's formula for polyhedra: V - E + F = 2
vertices - edges + faces = 2
So edges = vertices + faces - 2 = 18 + 11 - 2 = 27.
Answer:
27 edges.

Aman bought a computer for 24000 and its accessories pack worth for 1750. He sold it all for *26780. Find his gain and gain per cent.
Answers
Answer:
4%
Step-by-step explanation:
Gain percentage = 1030/25750 x 100 = 4%
Answer:
$1,030, 4%
Step-by-step explanation:
Aman spent $25,750 on a computer and accessory packs (totally worth it). He sold it for $26,780. So let's say Aman is at 0 before he bought this. He spent $25,750, so we subtract that from 0 to get -25,750. Then he sells it all for $26,780 (again totally worth it for the person buying). So we add 26,780 to the total.
-25,750 + 26,780 = 1,030
So Aman made a profit of $1,030 (now he can buy a REASONABLY priced MacBook Air or something)
So to find the percentage that he gained, we divide 1,030 by his original spending price, namely 25,750
1,030/25,750 = 0.04
Convert that to percentage form, you get 4%
Also, it's questions like this that make me question whether the people who write these questions into the textbooks should be talked to lol.
There are tulips, daisies, and daffodils growing in a garden. There are 2 times as
many daisies as tulips and 3 times as many daffodils as tulips. If there are 12
daisies, how many total flowers are in the garden?
Answers
if there is 2 times as many daisies as tulips it would be 6 tulips
3 x daffodils as tulips which would be 3 x 12 = 36
so 36+6= 42
42 + 12 = 54

Answers
Answer:
10 feet tall
Step-by-step explanation:
(Triangle problem was answered in a previous question)
So like before, we have a ratio: 1.5inches:2.5feet
We have a starting value as well: 6 inches
All we have to do is convert from inches to feet (not with a real life equation, but with the given equation)
To begin, dvide 6 by 1.5
6inches/1.5inches = 4 (The units canceled out during division)
Not multiply by the ratio:
4 * 2.5feet = 10 feet (It takes the units in feet)
Therefore, the tree is actually 10 feet tall.

Given y = a(x - h)^2 + k, p =
A. a
B. 4a
C. 1/4a
Answers
9514 1404 393
Answer:
C. 1/(4a)
Step-by-step explanation:
We assume you're comparing the vertex form ...
y = a(x -h)^2 +k
to the form used to write the equation in terms of the focal distance p.
y = 1/(4p)(x -h)^2 +k
That comparison tells you ...
a = 1/(4p)
p = 1/(4a) . . . . . . multiply by p/a; matches choice C
__
Additional comment
When using plain text to write a rational expression, parentheses are needed around any denominator that has is more than a single constant or variable. The order of operations requires 1/4a to be interpreted as (1/4)a. The value of p is 1/(4a).
When rational expressions are typeset, the fraction bar serves as a grouping symbol identifying the entire denominator:

The speed of object A is 1,500 mph faster than that of object B. If
object B travels 3,500 miles in the same amount of time that object A
travels 85,000 miles, then find the speed of object A.
Answers
Answer:
1564.42 mph
Step-by-step explanation:
Let a = Object A's speed
b = Object B's speed
a = b + 1500
a/85000 = b/3500
Let's make subtract 1500 from both sides of the first equation
a = b + 1500
- 1500 - 1500
b = a - 1500
Cross multiply the second equation
3500a = 85000b
Plug in the new b into this new equation
3500a = 85000(a - 1500)
3500a = 85000a - 127500000
Subtract 3500a and 127500000 from both sides
3500a = 85000a - 127500000
- 3500a - 3500a
0 = 81500a - 127500000
+ 127500000 + 127500000
127500000 = 81500a
Divide both sides by 81500
127500000/81500 = 81500a/81500
a = 1564.4171779141104
