THXSSSS UUUU SWOOOO MUCHHHHHHH
Step-by-step explanation:
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

Nick spent 34 minutes on the phone while routing 17 phone calls. In all, how many phone calls does Nick have to route to spend a total of 50 minutes on the phone? Assume the relationship is directly proportional.
Answer:
25 phone calls
Step-by-step explanation:
Create a proportion where x is the number of phone calls for 50 minutes on the phone:
[tex]\frac{34}{17}[/tex] = [tex]\frac{50}{x}[/tex]
Cross multiply and solve for x:
34x = 850
x = 25
So, Nick would have to make 25 phone calls
X + 12 >7

An object is dropped from a height of 150 feet. Its heights s at time, t is given by the
equation s(t) =-16t^2+150 ,where s is measured in feet and t is measured in seconds.
Find the average rate of change of the height over the interval [1, 2.5).
O 1) -56 ft/sec
O2) 77 ft/sec
03) 56 ft/sec
O4) -35 ft/sec
Answer:
The average rate of change of the height over the interval [1, 2.5] is - 56 feet per second.
Step-by-step explanation:
Let [tex]s(t) = -16\cdot t^{2} + 150[/tex]. Geometrically speaking, average rate of change over a given interval ([tex]\bar v[/tex]), measured in feet per second, is determined by definition of secant line, which is defined:
[tex]\bar v = \frac{s(t_{2})-s(t_{1}) }{t_{2}-t_{1}}[/tex] (1)
Where:
[tex]s(t_{1})[/tex], [tex]s(t_{2})[/tex] - Initial and final position of the object, measured in feet.
[tex]t_{1}[/tex], [tex]t_{2}[/tex] - Initial and final times, measured in seconds.
If we know that [tex]t_{1} = 1\,s[/tex] and [tex]t_{2} = 2.5\,s[/tex], then the average rate of change over the interval [tex][1,2.5][/tex]:
[tex]s(1) = -16\cdot (1)^{2}+150[/tex]
[tex]s(1) = 134[/tex]
[tex]s(2.5) = -16\cdot (2.5)^{2}+150[/tex]
[tex]s(2.5) = 50[/tex]
[tex]\bar v = \frac{50\,ft-134\,ft}{2.5\,s-1\,s}[/tex]
[tex]\bar v = -56\,\frac{ft}{s}[/tex]
The average rate of change of the height over the interval [1, 2.5] is - 56 feet per second.

Hi there!
Difference:
[tex]\frac{7}{8}[/tex]
1.Convert each fraction terms into a similar denominator:
[tex]1\frac{1}{4}=1\frac{2}{8}[/tex]
[tex]\frac{3}{8}=\frac{3}{8}[/tex]
2.Simplify term into mixed numbers:
[tex]1\frac{2}{8}=8+2=10:\frac{10}{8}=\frac{5}{4}[/tex]
3.Subtract the terms:
[tex]\frac{10}{8}-\frac{3}{8}=\frac{7}{8}[/tex]
Therefore, the difference in length between 1 1/4 and 3/8 is 7/8...

A rectangular prism has a volume of 3,510 feet cubed. It has a height of 12
feet and a length of 13 feet. What is it's width? *
Answer:
22.5 feet.
Step-by-step explanation:
Volume = length * height + width, so:
3510 = 13 * 12 * width
So width = 3510 / (13*12)
= 22.5 feet.

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.
