The clouds are 226.68 meters above the spotlight.

Step-by-step explanation:

Step 1:

The angle measuring device is 65 meters from the spotlight and the angle of elevation from the ground to the spot of light is 74°.

So a right-angled triangle can be formed using these measurements. The angle of the triangle is 74° while the opposite side of the triangle measures x meters while the adjacent side of the triangle measures 65 meters.

We need to calculate the opposites side's length of the triangle.

Step 2:

Since we have the adjacent side's length and need to calculate the opposite side's length we use the tan of the given angle.

The opposite side of the triangle = x meters.

$\tan \theta = \frac{oppositeside}{adjacentside} = \frac{x}{65}.$

$tan 74 = 3.487, x = 3.487(65) = 226.07.$

So the spot of light is 226.07 meters above from the spotlight.

Chico walks 3/5 mile to the library. Nikki walks 1/4 the distance that Chico walks to the library. How far does Nikki walk?

Effectus [21]

3/5 miles = 0.6 miles
0.6/4= 0.15 miles

Nikki walked 0.15 miles or 3/20 miles.

Multiply the bottom of the fractions together (4*5=20) and the tops (3*1=3) to get 3/20.

Two balls are drawn in succession out of a box containing 4 red and 3 white balls. Find the probability that at least 1 ball was

kifflom [539]

Answer:

A) 40/49

B) 36/42

Step-by-step explanation:

Given:

Red Balls, R : 4

White Balls, W : 3

Total Balls : 3+4=7 balls

A) If balls were replaced before the 2nd draw

P (White) = 3/7; P(Red) = 4

P(at least 1 red ball),

= 1 - P(no red balls)

= 1 - P(White, White)

= 1 - (3/7)(3/7)

= 1-(9/49)

= 40/49

A) If balls were replaced before the 2nd draw

P(1st White Ball) = 3/7 ; P(2nd White Ball) = 2/6

P(at least 1 red ball),

= 1 - P(no red balls)

= 1 - P(1st White, 2nd White)

= 1 - (3/7)(2/6)

= 1 - 6/42

= 36/42

[(x/x+3)+(3/x+3)+(2/x+3)] sum

nordsb [41]

You get the answer x+5/x+3.
This is because all of the fractions have the same denominator, so just add the numerators and put them over x+3.
