We replace y with x and x with y, and then we have:

$x=100-y^2$

Then we have $y = \sqrt{100-x}$

ZA and B are supplementary angles. If mA = (7x + 7)° and m

Wittaler [7]

Answer:

∠B = 54 °

Step-by-step explanation:

If sum of two angles add up to 180°, then the two angles are called supplementary.

m∠A + m ∠B = 180°

7x + 7 + 4x - 14 = 180

7x + 4x + 7 - 14 = 180

11x - 7 = 180

11x = 180 + 7

11x = 187

x = 187 ÷ 11

$\sf \boxed{x = 17^\circ}$

m∠B = 4x - 14

= 4*17 - 14

= 68 - 14

$\sf \boxed{\bf \angle B = 54^\circ}$

A bag contains 13 cards numbered 1 through 13. A card is randomly chosen from the bag. What is the probability that the card has

love history [14]

Think of it like this, if there are 13 cards numbered 1-13 and you need to find the probability of pulling a multiple of 3.

Then start by laying out all your options.

1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13

Then find all of the multiples of 3

3, 6, 9, 12

There are 4 multiples of 3 out of all of the cards so you have a 4 out of 13 chance to pull a card with a multiple of 3 on it.

Answer = 4/13
