Answer:
6.
volume=l×b×h=11×3×4=132in³
surface area =2(lb+bh+lh)=2(11×3+3×4+11×4)=178in²
7.
lateral surface area of traingular prism=perimeter of traingle ×length=[5+3+4]×6=72cm²
curved surface area=2[area oftraingle]=2×1/2×4×3
=12cm²
now
total surface area=72cm²+12cm²=84cm²

The circumference of a circular field is 266.9 yards. What is the radius of the field? Use 3.14 for π and do not round your answer. yards
Answers
Answer:
Hello! radius is 42.5
Step-by-step explanation:
266.9 ÷ 3.14 = 85 thats the diameter 85 but we want the radius so since we know diameter is twice the radius I divide by 2 to get the radius so 85 ÷ 2 = 42.5 so 42.5 is the radius Hope that helps!

$14.75 + ? = $15.70 what does it equal?
Answers
Answer:
Step-by-step explanation:
0.95
Answer:
0.95
Step-by-step explanation:
Step 1: Subtract the given from the given total
15.70 - 14.75 = 0.95
This was done because we are looking for the amount that is added to equal a total. To find that, we subtract because the opposite of addition is subtraction. To find the number needed to be added, we must do the opposite of what is being done. To confirm the answer was indeed correct;
Step 1: Add the given amount to the result found
14.75 + 0.95 = 15.7
It ends up the same. (Note: Zero is not a number so if there is a zero behind a decimal, it will be considered as nothing is there.) If we add a zero behind it, it will be exact.
Therefore, the answer equals 0.95

A line passes through the point (12,0) and is parallel to the line with the equation y = 1∕6x + 1. What's the equation of the line?
Answers
Answer:
y=1/6x-2
Step-by-step explanation:
Parralel lines have the same slope.
Since the slope of the parralel equation has to be 1/6, and the point is (12,0)
then you input 12 for x and get 2. But you need to get 0 for y, so the intercept would be negative 2.

Approximately 0.45 m. A mountain bike tire has a diameter of approximately. 0.6 m. In a 400-m race, how many more times will the BMX bike tire have to turn than the mountain bike tire?
Answers
Answer:
71 times
Step-by-step explanation:
Diameter of BMX bike= 0.45m
Radius= 0.225m
Cirumference of BMX bike
C= 2πr
C=2*3.142*0.225
C= 1.4139m
In a 400-m race, the BMX bike will turn
=400/1.4139
=282.9 times
=283 times
Diameter of Mountain bike= 0.6m
Radius= 0.3m
Circumference of Mountain bike
C= 2πr
C=2*3.142*0.3
C=1.8852m
In a 400-m race, the Mountain bike will turn
=400/1.8852
=212.17 times
=212 times
Hence the difference is
=283 -212
=71 times
Solve
x + y = 100 x -y = 10
Pair of Equation
Answers
lets take
x+y=100 firstly.
then x=100-y equation (i)
Now,
x-y=10
Putting value of x from equation(i)
100-y-y=10
-2y=10-100
-2y=-90
therefore, y=45
Now,
putting value of y in equation(i)
we get
x=100-45
ie x=55
hence, x=55 & y=45
Answer:
The solution is (55, 45).
Step-by-step explanation:
Solve the system of linear equations
x + y = 100
x - y = 10
through elimination by addition / subtraction.
Combining these two equations temporarily eliminates y, leaving us with 2x = 110. Then x = 55.
Substituting 55 for x in the first equation, we get:
55 + y = 100. Subtracting 55 from both sides leaves us with y = 45.
The solution is (55, 45).

What is the amplitude, period, and phase shift of f(x) = −3 cos(4x + π) + 6?
A. Amplitude = 3; period = pi over two; phase shift: x = negative pi over four
B. Amplitude = −3; period = pi over two; phase shift: x = pi over four
C. Amplitude = −3; period = negative pi over two; phase shift: x = negative pi over four
D. Amplitude = 3; period = 2π; phase shift: x = negative pi over four
Answers
Answer:Amplitude = 3.
Period = π/2.
Phase shift = -π/4
Step-by-step explanation: The given signal is
(x) = -3 cos(4x + π) + 6
The amplitude is |-3| = 3
If T is the period, then
(2π)/T = 4
4T = 2π
T = π/2
The period is π/2.
The phase shift is -π/4.
The vertical shift is 6.

An airplane is flying at an elevation of 15,000 feet. The airport is 6 miles away from a point directly below the airplane on the ground. How far is the airplane from the airport?
Answers
Answer:
The distance between the airplane and the airport is:
[tex]c=6.64\: miles[/tex]
Step-by-step explanation:
We can use the Pythagoras theorem to find the distance from the airplane to the airport.
The equation is:
[tex]c^{2}=a^{2}+b^{2}[/tex]
Where:
a represents the elevations of the airplane (15000 feet)b is the distance from the ground directly below the airplane to the airport (6 miles)c is the distance between the airplane and the airport.We need first to convert 15000 feet in miles.
[tex]15000\: feet \times \frac{0.00019\: miles}{1\: feet}=2.85\: miles[/tex]
Therefore, c will be:
[tex]c^{2}=a^{2}+b^{2}[/tex]
[tex]c=\sqrt{a^{2}+b^{2}}[/tex]
[tex]c=\sqrt{2.85^{2}+6^{2}}[/tex]
[tex]c=6.64\: miles[/tex]
I hope it helps you!
