HELP <br><br>Solve the formula E = /(R + r) for r.

ahrayia [7]

Answer:

r= RE/I

Step-by-step explanation:

E=I(R+r)

divide both sides by I

E/I = R+r

subtract both sides by R

R(E/I) = r

r = RE/I

mark as brainliest!!!! A flare was launched straight up from the ground with an initial velocity of 176ft/s and returned to the

soldier1979 [14.2K]

I think 484 is the answer because, 0=t(-16t+176) x=0 and x=11.To get the add up the x intercepts and divide by 2 you should get that x=5.5.

The Royal Fruit Company produces two types of fruit drinks. The first type is 20% pure fruit juice, and the second type is 95% p

enot [183]

Answer:

14 pints of 20% juice

56 pints of 95% juice

Step-by-step explanation:

Let

x be pints of 20% pure fruit juice, thus

70 - x will be pints of 95% pure fruit juice

The equation, thus can be written as:

20%x + 95% (70-x) = 80% (70)

Solving for x:

$(0.2)x + (0.95)(70-x) = (0.8)(70)\\0.2x+66.5-0.95x=56\\0.75x=10.5\\x=14$

And 70 - x would be 70 - 14 = 56

Thus,

14 pints of 20% juice is needed, and

56 pints of 95% juice is needed

A directed segment ST¯¯¯¯¯ is partitioned from S (−5,0) to T in a 32 ratio at point M (10, 15). What are the coordinates of poin

mart [117]

Answer:

Point T = (4,9)

Step-by-step explanation:

Given:

S (−5,0)

M (10, 15)

m1:m2 = 3:2

Find:

Point T

Computation:

X = [m1x2 + m2x1] / [m1+m2]

Y = [m1y2 + m2y1] / [m1+m2]

X = [(3)(10) + (2)(-5)] / [3+2]

Y = [(3)(15) + (2)(0)] / [3+2]

X = 20 / 5 = 4

Y = 45 / 5 = 9

Point T = (4,9)

Fernando has a prime number of books between 21 30. He says that if he takes 4 of the books away, he will be able to place the s

Inessa05 [86]

Answer: Fernando has 29 books

Step-by-step explanation:

The prime numbers between 21 and 30 are 23 and 29.

hence, the possible number of books Fernando has 23 or 29.

After taking 4 books away, the total number of books left can be :-

23-4=19

Since, 19 is not a square number so he cannot be able to place the same number of books on each shelf of his bookcase.

So Fernado doesn't have 23 books.

29-4=25

Also, $5^2=25$

Here, 25 is a square number so he will be able to place the same number of books on each shelf of his bookcase.

Therefore, Fernando has 29 books.
