does anyone know if each square weighs 5 pounds. what is the weight of a single triangle?
A right triangle is shown. One leg is labeled 5 and the other is labeled 13. A right angles is labeled in between the legs.
Mckenzie's Work Cara's Work
a2 + b2 = c2 a2 + b2 = c2
52 + 132 = c2 52 + b2 = 132
25 + 169 = c2 25 + b2 = 169
194 = c2 b2 = 144
Square root 194 equals square root c squared. Square root b squared equals square root 144.
13.93 ≈ c b ≈ 12
Who is right?
Answer:
Makenzie is correct, 13.93 ≈c
Step-by-step explanation:
the sides with determined lengths (see image) are A (13) and B (5). C however is not determined.
the correct equation would be to solve for c.
13² + 5² = c²
[tex]\sqrt {169 + 25} = c[/tex]
c ≈ 13.93
Clara solved for b and not c, which is incorrect.
The right working is as follows:
c² = a² + b²
c² = 5² + 13²
Using Pythagoras theorem,
c² = a² + b²
where
c = hypotenuse
a and b are the other two legs.
Therefore,
c = ?
a = 5
b = 13
c² = 5² + 13²
c² = 25 + 169
c² = 194
c = √194
c = 13.9283882772
c = 13.9 inches

you and a friend fill balloons with water. Two out of every 25 balloons pop while being fillied what percent of the balloons do not pop while they are being fillied
Answer:
92 percent
Step-by-step explanation:
Answer:
92% of balloons filled did not pop.
Step-by-step explanation:
2 / 25 balloons is the fraction of balloons that do pop, and we want the percentage that don't pop.
To start off with, we will get the fraction of balloons that don't pop - 23 / 25.
We will then convert this fraction to a decimal by dividing the fraction:
23 divided by 25 = 0.92
Now, to convert this to a percentage, we just multiply by 100.
0.92 x 100 = 92%
Therefore the answer is 92% of balloons filled did not pop.

When lit, a candle loses 8% of the unlit candle every hour. Janet lit a candle with an original height of 5 inches. Until the candle has been burning for at least ___ hours, the height of her candle will be more than four inches.
Please help! This was on a test but it’s confusing to me!
Answer:
2.5 hours
Step-by-step explanation:
We are given that
Original height of candle=5 in
Every hour candle loses =8% of 5 in=0.4
According to question
[tex]5-0.4x>4[/tex]
Subtract 4 from both sides we get
[tex]5-4-0.4x>0[/tex]
[tex]1-0.4x>0[/tex]
[tex]-0.4x>-1[/tex]
[tex]0.4x<1[/tex]
Divide by 0.4 on both sides
[tex]x<\frac{1}{0.4}[/tex]
[tex]x<2.5[/tex]
x=2.5 hours
Until the candle has been burning for at least 2.5 hours, the height of her candle will be more than four inches.
