c. 45.34ft
Step-by-step explanation:
When leg one of the triangle is 15ft and leg two is 17 ft you would take 17^2 + 15^2 and then you find the square root of that (514) to get the hypotenuse of the triangle. After that you multiply by two to account for the 2/2 sqaure foot per each unit

Volume can be measured by counting the number of unit cubic in a
three-dimensional figure.
what is Volume?The amount of space occupied by a three-dimensional figure as measured in cubic units.
Volume is the three- dimensional property, its basic units is always in cube.
Volume generally told us how much capacity can handle which we express it with the help of cubic units.
Volume doesn't wok on two dimensional bodies as well as the square is used for finding the area of the figure.
Thus, Volume can be measured by counting the number of unit cubic in a

Ronald runs 6,000 meters in 2 hours. He is thinking of running an 18 kilometers race. How much time will he take in the race if he maintains the same speed?
Answers
Answer:
6 hours
Step-by-step explanation:
speed = distance/ time
6000meters to km = 6000/1000= 6km
speed for the first race = 6/2
speed = 3km/hr
for the second race
speed = distance/time
3 = 18/time
cross multiply
3* t = 18
divide both sides by 3
t = 18/3
t = 6 hours
Answer:
Ronald will take 6 hours to complete the 18 km race if he maintains this speed.
Step-by-step explanation:
6000m in 2h = 6km in 2h
multiply by 3:
18km in 6h

Neil Down is doing some remodeling and needs to cut a triangular piece of wood such that the diagonal is 10 feet long, and the sides of the triangle are in a ratio 3:4. How long should each side be?
Answers
Answer:
6 and 8
Step-by-step explanation:
Pythagorean theorem: a² + b² = c²
Given this,
(3x)² + (4x)² = 10²
9x² + 16x² = 100
25x² = 100
Divide both sides by 25
x² = 4
x = 2
Substitute this into 3x and 4x.
3x = 3 * 2 = 6
4x = 4 * 2 = 8
Thus, the answer is 6 and 8

Margin of error is 4.645% with 95% confidence that the mean number of hours all the residents of the city are watching news on television is 1.8 .
Data given :
A researcher surveyed 220 residents of a city about the number of hours they spend watching news on television each day. The mean of the sample was 1.8 with a standard deviation of 0.35 .
The researcher can be 95% confident that the mean number of hours all the residents of the city are watching news on television is 1.8 with what margin of error,
By formula of margin of error = [tex]M = 1.96 \times S / \sqrt{N} ,[/tex]
[tex]Margin \ of \ error, \ M = z \times \frac{s}{\sqrt{N}}[/tex]
z - represents the z-value for the required confidence level .
s - represents the standard deviation of the sample .
N - represents the sample size .
Now, using the above information, compute the margin of error as -
[tex]\therefore \ Margin \ of \ error, \ M = z \times \frac{s}{\sqrt{N}} \\= 1.96 \times \frac{0.35}{\sqrt{220}}[/tex]
[tex]=0.04625 (rounded \ to \ 5\ decimal\ places) \\\\ =4.625\%[/tex]
Thus, the margin of error, M, is approximately 4.625% .

State whether f^-1 (x) is a function given the equation
Answers
Answer:
We have that [tex]f(a) = f(b)[/tex] if [tex]a = \pm b[/tex], which does not respect the condition for the existence of an inverse function, which means that [tex]f^{-1}(x)[/tex] does not exist for this function.
Step-by-step explanation:
Existence of an inverse function:
An inverse function will exist if: f(a) = f(b) only if a = b.
In this question:
[tex]f(a) = -\frac{1}{7}\sqrt{16 - a^2}[/tex]
[tex]f(b) = -\frac{1}{7}\sqrt{16 - b^2}[/tex]
[tex]-\frac{1}{7}\sqrt{16 - a^2} =-\frac{1}{7}\sqrt{16 - b^2}[/tex]
[tex]\sqrt{16 - a^2} = \sqrt{16 - b^2}[/tex]
[tex](\sqrt{16 - a^2})^2 = (\sqrt{16 - b^2})^2[/tex]
[tex]16 - a^2 = 16 - b^2[/tex]
[tex]a^2 = b^2[/tex]
[tex]a = \pm b[/tex]
We have that [tex]f(a) = f(b)[/tex] if [tex]a = \pm b[/tex], which does not respect the condition for the existence of an inverse function, which means that [tex]f^{-1}(x)[/tex] does not exist for this function.

The slope of side CD in rhombus CDEF is -2/5. Therefore, option B is the correct answer.
What is a rhombus?A rhombus can be defined as a special parallelogram as it fulfills the requirements of a parallelogram, i.e. a quadrilateral with two pairs of parallel sides. In addition to this, a rhombus has all four sides equal just like a square. That is why it is also known as a tilted square.
Given that, the rhombus is CDEF and the slope of FC is 5/2.
Here, sides FC and CD are perpendicular.
The slope of a line perpendicular to given line is m₁=-1/m₂
Slope of CD is -2/5.
Therefore, option B is the correct answer.
