A. 1,430 square inches
B. 1,672 square inches
C. 4,356 square inches
D. 836 square inches
Factor. 125x^3-64y^3
Answer:
= 5x - 4y
Step-by-step explanation:
125x³- 64y³
= 5x - 4y
Answer:
Hello,
(5x)^3 - (4y)^3
Step-by-step explanation:
125 = 5^3
64 = 4^3
125 x^3 - 64 y^3 = (5x)^3 - (4y)^3
Simplify:
a) 6c + 4d - c - 7d =

d) 8t + 3r - 7t - 9r =
Answer:
a) 5c-3d
b) 2x+7y
c) 7g+3h
d) 1t-6r

Answer:
a) 6c + 4d - c - 7d = 5c -3d
b) 3x + 5y - x + 2y = 2x + 7y
c) 3g + 5h + 4g - 2h = 7g + 3h
d) 8t + 3r - 7t - 9r = t - 6r
Step-by-step explanation:

Answer:
x = 0.3, y = 5.3, z = 17.3
Step-by-step explanation:
Since given question is incomplete, so here is the complete table for the distance from the mean.
Temp (°F) 29 38 45 31 50 58 62
Distance from the mean 15.7 6.7 x 13.7 y 13.3 z
It's given that the mean of the data is 44.7
Since distance from the mean of a data is the absolute value of the difference of data and mean,
Therefore, distance from the mean of the data will be,
x = |44.7 - 45| = 0.3 (absolute value of the difference)
y = |44.7 - 50| = 5.3
z = |44.7 - 62| = 17.3
Answer:
x = 0.3
y = 5.3
z = 17.3

You are wakeboarding on a river. You travel 2 miles downstream to a marina for supplies, and then you travel 3 miles upstream to a dock. The boat travels x miles per hour during the entire trip, and the river current is 3 miles per hour.
How long will the trip take when then speed of the boat is 18 miles per hour? Round to the nearest tenth minute.
Answer:
17.3
Step-by-step explanation:
(2+18)=(20mph*2miles)=6 minute
(18-2)=16mph*3miles=11.25

Find the length of the base of the following pyramid, given the height of the pyramid is 221 meters and the angle of elevation of the base of the pyramid is 62°. Round to the nearest whole number.
An image of a square pyramid is shown with a right triangle embedded inside it. The face is at an incline of 62 degrees. The height is labeled 211, and the corner of the right angle is marked with a letter P.
75 meters
189 meters
235 meters
416 meters
Answer:I believe it would be answer choice, 235 meters
Step-by-step explanation:
I’m not super good at explain but, the height and incline both go at the right slope when they interact. Have a good day, hope it helps.
The length of the pyramid's base would be:
C). 235 meters
Find the length of the baseGiven that,
Height of the pyramid [tex]= 221[/tex]
Elevation/angle of the base [tex]= 62[/tex]°
Employing the trigonometric function,
Tan 62 [tex]= 221/[1/2 base][/tex]
⇒ Base [tex]= (2[/tex] × [tex]221)[/tex][tex]/Tan[/tex][tex]62[/tex]
[tex]= 2[/tex] × 221/[tex]1.88[/tex]
[tex]= 235.10[/tex]
Thus, option C is the correct answer.

The solution to the equation is x = 7, -1.
What is a quadratic equation?The equation of the form ax² + bx +c is known as a quadratic equation.
The given equation is 2.1/x + 1 (4/5) =(3/10)x.
Simplify the equation as follows:
2.1/x + 1 (4/5) =(3/10)x
2.1/x + 9/5 = (3/10)x
2.1 + (9/5)x = (3/10)x²
21 + 18x = 3x²
3x² - 18x -21 =0
3x² - 21x + 3x -21 =0
3x(x - 7) + 3(x - 7) =0
(x - 7)(3x + 3) =0
x - 7 =0 or 3x + 3 =0
x = 7 or x = -1
Hence, the solution to the equation is x = 7, -1.

The angular velocity of a fan blade is 6.2 radians per second.
Approximately how many revolutions does the fan blade make in 1.6 minutes?
Enter your answer, rounded to the nearest tenth of a revolution
Answer:
94.7 revolutions
Step-by-step explanation:
In the question above, we are given the following values for the fan
Angular velocity = 6.2 radians per seconds
Time = 1.6 minutes.
Step 1
We would convert the time given to seconds
1 minute = 60 seconds
1.6 minutes = ?
We cross multiply
1.6 minutes × 60 seconds
= 96 seconds
Step 2
Number of revolutions made by the fan is calculated as :
Angular velocity(rad/s)
× time(seconds)
Number of revolutions = 6.2 radians per seconds × 96 seconds
=595.2 radians
Converting from radians to revolution
1 radian = 0.159155 revolutions
595.2 radians =
Cross multiply
= 595.2 radians × 0.159155 revolutions
= 94.729056 revolutions.
Approximately to the nearest tenth = 94.7 revolutions.
Therefore, the number of revolutions the fan blade makes in 1.6 minutes is 94.7 revolutions.
1.6 minutes is 1.6 x 60 = 96 seconds.
Its angular velocity is 6.2 radians per second: 6.2 radians/second x 96 seconds = 595.2 radians.
One revolution of the fan is one circumference of the fan, which is 2pi radians.
Dividing 595.2 radians by 2pi radians gives us an answer of 94.7 revolutions.
