Tyrel And Diego are playing basketball. Together they scored 45 points.Tyrel scored two times as many points as Diego. How many
pshichka [43]

Answer:

Tyrel scored 30 and Diego scored 15

Step-by-step explanation:

This is because the ratio of the score is 2:1  (Tyrel : Diego)

and if you add that together you get 3

which means you have to divide 45 by 3 which gives you 15

and this means I part = 15

so with the ratio 2:1 you have to multiply 15 by each ratio

so 15 x 2 = 30 and 15 x 1 = 15

which gives you 30 and 15

Find the length (distance) of a segment with endpoints (5,-2) and (9,4). (Must show your
stepladder [879]

Answer:

7,2 ≈ D

Step-by-step explanation:

We need to use the Distance Formula:

\sqrt{(-x_{1} + x_{2})^{2}  + (-y_{1} + y_{2})^{2}} = D \\  \\  \sqrt{(-5 + 9)^{2} + (2 + 4)^{2}} = D \\  \\ \sqrt{{4}^{2} + {6}^{2}} = D \\  \\ \sqrt{16 + 36} = D \\ \\ 2\sqrt{13} = D \\ \\ 7,2 ≈ D

** Since we are talking about <em>distance</em>,<em> </em>we ONLY want the NON-NEGATIVE root.

I am joyous to assist you anytime.
