Answer:

28 units

Step-by-step explanation:

The graph goes up by 4 so, since ada and eve's house are on the same x point, you count the amount of space on the y-axis and multiply by 4. Then, you count the space on the x-axis between eve's house and the pool and then multiply by four, and then add both the answers. The space between to the two houses is 4*4=16 and then the space between the house and the pool is 3*4=12. 16+12=28 units.

A 25 foot ladder is leaning against a house. If the angle of Elevation of the ladder is 72 degrees:

coldgirl [10]

Answer:

1. 23.8

2. 7.7

Step-by-step explanation:

for the first blank

use sin because x is opposite and 25 is hypotenuse

set up an equation:

sin(72)= (x/25)

multiply both sides by 25:

25(sin(72))= (x/25)25

25(sin(72))= x

multiply 25 by sin(72):

23.8 = x

for the second blank

use cos because x is adjacent and 25 us hypotenuse

set up an equation:

cos(72)= (x/25)

multiply both sides by 25:

25(cos(72))= (x/25)25

25(cos(72))= x

multiply 25 by cos(72):

7.7= x

If there are 17 green marbles in a jar of 65 marbles, what is the probability of drawing 2 green marbles at random without repla

erastovalidia [21]

Answer:

Option b) $\frac{17}{260}$

Step-by-step explanation:

We are given the following information in the question:

Total number of marbles = 65

Number of green marbles = 17

We have to find the probability of drawing 2 green marbles at random without replacement.

Formula:

$Probability = \displaystyle\frac{\text{Number of favourable outcomes}}{\text{Total number of outcomes}}$

$\text{P(Drawing 2 green marbles at random without replacement)} = \\\text{Probability of drawing }1^{st} \text{ green marble}\times \text{Probability of drawing }2^{nd} \text{ green marble}$

$\text{Probability of drawing }1^{st} \text{ green marble} = \displaystyle\frac{17}{65}\\\\\text{Probability of drawing }2^{nd} \text{ green marble} = \displaystyle\frac{16}{64}$
