Answer:
9 students in music class.
Step-by-step explanation:
In art there are 4 and since there are 8 more 8 + 4 = 12. so there are 12 in Art.
4 x _ = 12. —> 4 x 3 = 12.
so we need to do the same for music class.
For music there are 3.
so we multiply by 3 like we did with the 4.
3 x 3 = _ —> 3 x 3 =9.
so there are 9 students in music class.
Answer:
Step-by-step explanation:
Alright, lets get started.
Suppose car was driven x miles in its 4 days trip.
Cost of a car rental is thirty dollar per day.
So, for 4 days, the car rental will be =
$
For 1 mile, it adds fifteen cents,
So, for x miles, the cost will be =
$
As per question, total rent is 180 $
Total rent will be =
Subtracting 120 in both sides



It means car was driven 400 miles. : Answer
Hope it will help :)
Two lines are perpendicular between each other if their slopes fulfills the following property

where m1 and m2 represents the slopes of line 1 an 2, respectively.
To find the slope of a line we can write it in the form slope-intercept form

Our original line is

Then its slope is

Now we have to find the slope of the second line. Using the first property,

Then the second line has to have a slope of 8.
The options given to us are:

Then we have to determine which of these options have a slope of 8. To do that we write them in the slope-intercept form:

Once we have the options in the right form, we note that the only one of them that has a slope of 8 is the last one.
Then the line perpendicular to the original one is
H x 5=h5
h5/8
I think it’s this it also may be
(h x 5)/8

<u>Trigonometric Identities</u>
If the trigonometric function value of an angle is given, we can find the rest of the trigonometric values of the angle by using one or more of the fundamental identities.
To solve this problem, we need to use the following identities:


Since we are given:

And the angle is in the first quadrant, calculate the cotangent:



The tangent is:

Rationalizing the denominator:
