Answer: Rectangular prism
Step-by-step explanation:
Details culled from the information supplied :
1.) A 3 - dimensional figure
2.) Four rectangular faces
3.) Two square faces
Using the above information to form the basis of our inference, It could be inferred that the figure of Rhett's house is a rectangular prism.
Three dimensions: length, width, and height
Six faces in total; four of which are rectangular and 2 squared faces.
Answer: the remaining credit after 79 minutes of call is $15.52
Step-by-step explanation:
let x represent the number of minutes of call.
Let y represent the remaining credit after x minutes of call.
If we plot y on the vertical axis and x on the horizontal axis, a straight line would be formed. The slope of the straight line would be
Slope, m = (17.2 - 19.84)/(65 - 43)
m = - 2.64/22 = - 0.12
The equation of the straight line can be represented in the slope-intercept form, y = mx + c
Where
c = intercept
m = slope
To determine the intercept, we would substitute x = 65, y = 17.2 and m = - 0.12 into y = mx + c. It becomes
17.2 = - 0.12 × 65 + c
17.2 = - 7.8 + c
c = 17.2 + 7.8
c = 25
The linear function becomes
y = - 0.12x + 25
Therefore, the remaining credit after 79 minutes of call is
y = - 0.12 × 79 + 25
y = - 9.4 + 25
y = 15.52
Answer:
Part 1) The exact value of the arc length is \frac{25}{6}\pi \ in
Part 2) The approximate value of the arc length is 13.1\ in
Step-by-step explanation:
ind the circumference of the circle
The circumference of a circle is equal to
C=2\pi r
we have
r=5\ in
substitute
C=2\pi (5)
C=10\pi\ in
step 2
Find the exact value of the arc length by a central angle of 150 degrees
Remember that the circumference of a circle subtends a central angle of 360 degrees
by proportion
\frac{10\pi}{360} =\frac{x}{150}\\ \\x=10\pi *150/360\\ \\x=\frac{25}{6}\pi \ in
Find the approximate value of the arc length
To find the approximate value, assume
\pi =3.14
substitute
\frac{25}{6}(3.14)=13.1\ in
You must travel at 42 mph for 4 hours
<em><u>Solution:</u></em>
Time varies inversely as rate of motion
Let "t" be the time required
Let "r" be the rate of motion
Then, we get
Where, "k" is the constant of proportionality
<em><u>You travel 3 hours at a rate of 56 mph</u></em>
Substitute t = 3 and r = 56 in eqn 1
<em><u>Find the rate you must travel for 4 hours</u></em>
r = ? and t = 4
Substitute t = 4 and k = 168 in eqn 1
Thus you must travel at 42 mph for 4 hours
The answers D
Step-by-step explanation:
the answer is D because to fine slope, you have to do rise over run
hope this help : )
