The perimeter of a square with a side measurement of 6 inches is equal to 24 inches.
Answer:
Step-by-step explanation:
Similar triangles
Cross multiply
2*(x+2) = 3*x
2x + 2*2 = 3x
2x + 4 = 3x
Subtract 2x from both sides
2x + 4 -2x = 3x - 2x
4 = x
x = 4
Answer:
if I am right Renee would have 82.00 because Lexi has 13.00 less than Renee and together their money's adds up to 95.00 so if you take 13.00 from 95.00 you will have 82.00 that in my opinion
Answer:
So, remember that:
cos(x) > 0 for -pi/2 < x < pi/2
cos(x) < 0 for pi/2 < x < (3/2)*pi
and
sin(x) > 0 for 0 < x < pi
sin(x) < 0 for -pi < x <0 or pi < x < 2pi
Also, we have the periodicty of the sine and cocine equations, such that:
sin(x) = sin(x + 2pi)
cos(x) = cos(x + 2pi)
Now let's solve the problem:
here we have:
x = (13/36)π
This is larger than zero and smaller than π:
0 < (13/36)π < π
then:
Is positive.
The next one is:
Here we have x = (7/12)*pi
notice that:
7/12 > 1/2
Then:
(7/12)*π > (1/2)*π
Then:
is negative.
next one:
here:
x = (47/36)*π
here we have (47/36) > 1
then:
(47/36)*π > π
then:
is negative.
the next one is:
Here we have x = (17/10)*π
if we subtract 2*π (because of the periodicity) we get:
(17/10)*π - 2*π
(17/10)*π - (20/10)*π
(-3/10)*π
this is in the range where the cosine function is positive, thus:
is positive.
the next one is:
here we have:
x = (41/36)*π
Notice that both functions, sine and cosine are negatives for that value, then we have the quotient of two negative values, so:
is positive.
The final one is:
Here:
x = (5/9)*π
The sin function is positive with this x value, while the cosine function is negative, thus:
Is negative.
