Answer: A = 128 in^2
Explanation:
Assume:
X is the width
And 2x is the length
We know Perimeter = 48
P = 2(x + 2x) = 48
2x + 4x = 48
6x = 48
x = 8
Now we found the width which is 8
And the length is 2 times the width which is 8 x 2 = 16
Now that we have both length and width we can find the area
A = 16 x 8 = 128
Answer:
Yes D is the correct answer :)
Answer:
A
Step-by-step explanation:
The lateral surface area is given by pi*r*l, we can use trigonometry to find l. 8*sqrt(3)/l=sin(60), l=16 and r is given by tan(60)=8*sqrt(3)/r, r=8. The lateral surface area is 16*8*pi=128*pi
Answer:
2 because if x=0 y=1 and 2 is closest so a and b
Step-by-step explanation:
x = number of multiple choice questions
y = number of short response questions
x + y = 15
5x + 10y = 100
=>
x + 2y = 20
let's subtract the first from the second equation :
x + 2y = 20
- x + y = 15
--------------------
0 y = 5
x + y = 15
x + 5 = 15
x = 10
to graph you need to consider both equations as linear functions. and you need to transform them into e.g. a slope intercept form : y = ax + b
a is the slope, b is the y- intercept.
x + y = 15
transforms to
y = -x + 15
this line goes e.g. through the points (0, 15) and (1, 14).
and
x + 2y = 20
transforms to
2y = -x + 20
y = -x/2 + 10
this line goes e.g through (0, 10) and (2, 9).
the crossing point of both lines is the solution and should therefore be the point (10, 5) as calculated above.
