Im not getting exact answers but the closest was D. What i did was i graphed the points and i found the slope and then i found the y intercept. so the equation was y = 2/3x + .67. and i plugged in the points. so i would say the answer is D. because since i rounded the .67 it wasn't exact but it was close

If angle P measures 50 degrees, what is the measure of angle Q?

dolphi86 [110]

Answer:

130 degrees

Step-by-step explanation:

Since angles P and Q are supplementary (meaning that they add up to 180), we can set up the equation:

180 = 50 + Q

Q = 130

90% of a number is x . What is 100% of the number? Assume x>0

mariarad [96]

Step-by-step explanation:

Let the required number be n

$\therefore \: \frac{90}{100} \times n = x \\ \\ \therefore \: \frac{9}{10} \\ \\ \therefore \:n = \frac{10}{9} x \\ \\ \therefore 100\% \: of\:n = \frac{10}{9} x \times 100\% \\ \\ = \frac{10}{9} x \times \frac{100}{100} \\ \\ = \frac{10}{9} x \\$

NOTE: A number is always 100% in itself.

ABC ~ DEF and the scale factor from ABC to DEF is 1/2, what are the lengths of DE

Likurg_2 [28]

Answer:

Step-by-step explanation:

ABC ~ DEF means that ABC and DEF are the same triangle either expanded or contracted.

In this case the scale factor is 1/2. That means DEF is half ABC.

Since AB = 26 then DE must be 26/2 = 13
