Checking, it all looks ok except for the range in number 7.

3 is a line with a slope so all reals (which you've written negative infinity to infinity, fine) make up both the domain and range.

4 is a parabola in the usual orientation, so a domain of all reals. There's a minimum so a range of y >= -1.

Priya noticed in the last activity that between the 2 triangles, you only need to know 4 angles to show that they are similar. S
ValentinkaMS [17]

Answer:

Please find attached a drawing of the triangles ΔRST and EFG showing the angles

The angle on ΔEFG that would prove the triangles are similar is ∠F = 25°

Step-by-step explanation:

In order to prove that two triangles are similar, two known angles of each the triangles need to be shown to be equal

Given that triangle ∠R and ∠S of triangle ΔRST are 95° and 25°, respectively, and that ∠E of ΔEFG is given as 90°, then the corresponding angle on ΔEFG to angle ∠S = 25° which is ∠F should also be 25°

Therefore, the angle on ΔEFG that would prove the triangles are similar is ∠F = 25°.

Soon-Jin sent out 48 invitations, this was 4/5 of all her invitations. How many invitations will she send out in total?
stepladder [879]
If 4/5 of the total is 48, the total can be found by dividing it by 4 and multiplying it by 5:
48/4 = 12
12*5 = 60.
