5/9 hope this helps :)
25/45 their common number that both are divisible by is 5.
25 divided by 5 = 5
45 divided by 5 = 9
Therefore, 5/9 would be your answer because you cannot reduce the numbers anymore as 5 and 9 do not have common divisables

Make d the subject of the formula where d is positive
-5d + y = 6dc + 5a

Answers

Answer:

[tex]d = \frac{y - 5a}{5 + 6c}[/tex] if 5 + 6c is not 0.

Step-by-step explanation:

-5d + y = 6dc + 5a

first let's move all d's to one side and the rest to the other

-5d -6dc = 5a - y

5d + 6dc = y - 5a

d(5 + 6c) = y - 5a

if (5 + 6c) isn't 0:

[tex]d = \frac{y - 5a}{5 + 6c}[/tex]

Answer:

d = [tex]\frac{y-5a}{5+6c}[/tex]

Step-by-step explanation:

Given

- 5d + y = 6dc + 5a ( subtract 6dc from both sides )

- 5d - 6dc = 5a - y ← factor out - d from each term on the left

- d(5 + 6c) = 5a - y ( multiply through by - 1 )

d(5 + 6c) = y - 5a ← divide both sides by (5 + 6c)

d = [tex]\frac{y-5a}{5+6c}[/tex]

Answers

Answer: The 4th term is 11.

Step-by-step explanation:

The given sequence: [tex]C(n) = -7 + 6(n - 1)[/tex] which represents the nth term.

To find 4th term.

Put n=4, we get

[tex]C(4) = -7 + 6(4 - 1)\\\\\Rightarrow\ C(4) = -7 + 6(3)\\\\\Rightarrow\ C(4) =-7+18\\\\\Rightarrow\ C(4) =11[/tex]

Hence, the 4th term is 11.

Answers

Answer:

(1/3)πr2h.

Step-by-step explanation:

Volume of a cone:

V = (1/3)πr2h

Slant height of a cone:

s = √(r2 + h2)

Lateral surface area of a cone:

L = πrs = πr√(r2 + h2)

Base surface area of a cone (a circle):

B = πr2

Total surface area of a cone:

A = L + B = πrs + πr2 = πr(s + r) = πr(r + √(r2 + h2))
