A student wants to save at least $5000 for college. She begins with a savings account set up by her parents containing $2,500. E
Tamiku [17]

Answer: She deposits 50 dollars per month right? But as known her parents deposited her 2,500. So, it will take her 50 months to complete the amount of  5000 dollars needed for college.

Step-by-step explanation: Im not good with equations but here  we go.

First: AS we know the account already had 2,500, and every month she deposits 50$.

What we can do is to divide 2,500 divided by 50 which will be 50.

find the missing angle and side measures of the triangle. The triangle has one angle that measures 90 degrees, and the other two
Tamiku [17]
Since we know that the measure of one of the angles is 90°, we know that we have a right triangle with legs 1 and \sqrt{3}. Now lets apply the Pythagorean theorem: hypotenuse= \sqrt{leg^{2}+leg^{2}  }, to find our hypotenuse:
h= \sqrt{1^{2}+ \sqrt{3}^{2}   }
h= \sqrt{1+3}
h= \sqrt{4}
h=2

Now that we know that the measure of the hypotenuse is 2, lets use the trig function sine to find one of the angles that we are going to call x.
Remember that sin(x)= \frac{opposite.side}{hypotenuse}, so:
sin(x)= \frac{1}{2}
x=sin^{-1} ( \frac{1}{2} )
x=30
Now that we have two angles, remember that the sum of the interior angles of a triangle is 180°; lets use that to find our final angle y:
y=180-(90+30)
y=180-120
y=60

We can conclude that the measure of the hypotenuse of our triangle is 2, and the measure of its missing angles are 30° and 60° respectively.

3(a + 4) = 3a + 4<br><br> Question 3 options:<br> True<br> False
sattari [20]
Simple...

you have: 3(a+4)=3a+4

You're deciding whether it's true or false..to do so, simplify it..

3(a+4)=3a+4

3*a=3a
3*4=12

3a+12=3a+4

As we can see here, they do no match. False.

Thus, your answer.
