Answer:

63 points

Step-by-step explanation:

So you are trying to find out how many points you scored on the test when you got 90%,

we could do that by:

--------

70 (The totals points of the test) × 0.9 (The percentage converted into a decimal) = 63

--------

Let's double check,

so you got 63 out of 70, so when we divide 63 by 70, you would get 0.9.

0.9 converted into a percentage is 90%

Have a good day :)

Find the area of the triangle. A= 125°, b= 9, c= 6
Semmy [17]

The area of given triangle is: 22.1184

Step-by-step explanation:

When we only know two sides of a triangle and the included angle then the area of triangle is given by:

A = \frac{1}{2} * side\ 1 * side\ 2 * angle

Given

b = 9

c = 6

∠A = 125°

So the formula will be:

A = \frac{1}{2} bc * sin\ A\\A = \frac{1}{2} * 9 * 6 * sin\ 125\\A = 27 * 0.8192\\A = 22.1184

Hence,

The area of given triangle is: 22.1184

Y=-2 y=3x+1 in graph
Airida [17]

Answer:

The solution of the system is x=-1, y=-2

Step-by-step explanation:

we have

y=-2 ----> equation A

y=3x+1 ----> equation B

Solve the system by graphing

Remember that the solution of the system is the intersection point both lines

using a graphing tool

The intersection point is (-1,-2)

see the attached figure

therefore

The solution of the system is x=-1, y=-2
