Mathematics

Answer:

Step-by-step explanation:

we know the line goes through the origin, so we have point (0,0). next, find another point the line goes through. for example, point (2,4)

the slope formula for points (x1, y1) and (x2, y2) is (y2 - y1) / (x2 - x1). plug in the 2 points to get (4-0)/(2-0) = 4/2 = 2

Mr. Martin’s math test, which is worth 100 points, has 29 problems. Each problem is worth either 5 points or 2 points. Let x be

klio [65]

(x + y = 29)
(y = 29 - x)
(5x + 2(29 - x) = 100)
(5x + 58 - 2x = 100)
(3x = 42)
(x = 14)
(y = 15)
(14 5-point questions and 15 2-point questions)

What is the distance across the lake?

vredina [299]

Given:

Height of right triangle = 9 mi

Hypotenuse = 17.5 mi

Base of right triangle = Distance across lake

To find:

The distance across the lake.

Solution:

Using Pythagoras theorem:

In right triangle, square of the hypotenuse is equal to the sum of the squares of the other two sides.

$\Rightarrow 9^2+base^2=(17.5)^2$

$\Rightarrow 81+base^2=306.25$

Subtract 81 from both sides.

$\Rightarrow 81+base^2-81=306.25-81$

$\Rightarrow base^2=225.25$

Taking square root on both sides.

⇒ base = 15

The distance across the lake 15 mi.

The tree diagram represents an experiment consisting of two trials.<br><br>P(A and C) = [?]

schepotkina [342]

Yo sup??

To find P(A and C) we have to simply multiply the probabilities of getting an A with that of getting a C

P(A)=0.6

P(C|A)=0.3

P(A and C)=0.6*0.3

=0.18

Hope this helps.
