Answer:
$189
Step-by-step explanation:
Let their total amount of spending money be x
given that $135 they spent is 5/7 of their total spending money,
mathematically:
135 = (5/7) x (multiply both sides by 7)
135 (7) = 5x
945 = 5x
5x = 945 (divide both sides by 5)
x = 945 / 5
x = 189
Answer:
Step-by-step explanation:
As you can see from the graph I attached you, the possible solutions in the interval from 0 to 2π are approximately:

So, it's useful to solve the equation too, in order to verify the result:

Taking the inverse sine of both sides:

Using this result we can conclude the solutions in the interval from 0 to 2π are approximately:

Weight = mass * g where g = gravitational force
so a weight of 150 pounds would be 150 / 6 = 25 on the moon.
The mass would be the same as on earth.
Root root 20^2 - 4^2
X = 2
Answer:

Step-by-step explanation:
In leftmost triangle:
opposite side =y
adjacent=a
now, we can use trig formula

now, we can solve for y

In rightmost triangle:
adjacent=b
opposite=y
a+b=15
b=15-a
now, we can use trig formula

now, we can solve for y

now, we can set them equal
and then we can solve for a




now, we can find b


now, we can use trig formula

now, we can find z

we can simplify it
and we get
