Step-by-step explanation:
For every cup there is 0.0625 liquid gallons. To find 3 cups times 0.0625 x 3 then you get the answer 0.1875 liquid gallons. Please give me the brainliest answer.
Answer:
The probability of drawing a second red card, since the first card is red is 25/51
Step-by-step explanation:
The probability of drawing a second red card since the first Card is red is:
P (R2 | R1) = P (R2 and R1) / R1
So:
P (R2 | R1) = (25/102) / 1/2
P (R2 | R1) = 25/51
Therefore the correct option is option 2.
the probability of drawing a second red card, since the first card is red is 25/51
To simplify the expression we proceed as follows:
<span>d^2+4d+3/d^2-7d-8 + d^2-2d-8/d^2+5d+6
putting like terms together we have:
(d^2+d^2)+(4d-7d-2d+5d)+(3/d^2-8/d^2)+(-8+6)
=2d^2+0d-5/d^2-2
=2d</span>²-5/d²-2
Answer: 2d²-5/d²-2
Answer:
Step-by-step explanation:
<em>Refer to attached picture</em>
- The height = h
- Angles of elevation 22.6° and 38.3°
- Closer distance = d
<u>Use tangent to solve</u>
- tan 22.6° = h/(d + 17) ⇒ h = (d + 17) tan 22.6° ⇒ h = 0.42(d + 17)
- tan 38.3° = h/d ⇒ h = d tan 38.3° ⇒ h = 0.79d
<u>Compare the equations above and find the value of d:</u>
- 0.42(d + 17) = 0.79d
- 0.42d + 7.14 = 0.79d
- 0.79d - 0.42d = 7.14
- 0.37 d = 7.14
- d = 7.14/0.37
- d = 19.3 m
<u>Now find the value of h:</u>
- h = 0.79d
- h = 0.79*19.3
- h = 15
