Answer:

d. 15.3%

Step-by-step explanation:

There are a total of 4 + 10 + 7 + 5 = 26 marbles

P(pick a red) = 4/26 = 2/13 = .153 = 15.3%

If a and b are two angles in standard position in Quadrant I, find cos(a-b) for the given function values. sin a=3/5and cos b=12

goldfiish [28.3K]

The identity in question is

cos(a - b) = cos(a) cos(b) + sin(a) sin(b)

so that

cos(a - b) = 12/37 cos(a) + 3/5 sin(b)

Since both a and b lie in the first quadrant, both cos(a) and sin(b) will be positive. Then it follows from the Pythagorean identity,

cos²(x) + sin²(x) = 1,

that

cos(a) = √(1 - sin²(a)) = 4/5

and

sin(b) = √(1 - cos²(b)) = 35/37

So,

cos(a - b) = 12/37 • 4/5 + 3/5 • 35/37 = 153/185

Is there more wood in a 60-foot-high tree trunk with a radius of 2.2 feet or in a 50-foot-high tree trunk with a radius of 2.6

Sladkaya [172]

Answer:

V₂=1061.85 ft³

Step-by-step explanation:

To determine where more wood is found, just find the volume of each log and see which one has the largest volume

knowing that the volume of a straight cylinder is

V=πR²h, where R=radius and h=height

$V_{1}=\pi (2.2)^{2}60= 912.31ft^{3}\\V_{2}=\pi (2.6)^{2}50= 1061.85ft^{3}$

As we can observe

V₂>V₁

4. Jim and Kirk are playing a card game where they trade chips. At the beginning of the game, Jim has four times as many chips a

s2008m [1.1K]

Answer:

(a) $j = 4k$

(b) $4k - 18 = 18 + k$

Step-by-step explanation:

Given

$j = Jim$

$k=Krik$

Solving (a): An equation for the amount they originally had.

From the question, we understand that j is 4 times as many as k.

Mathematically, this is:

$j = 4 * k$

$j = 4k$

Solving (b): Equation after Kirk wins

Initially Kirk had k.

To get the new expression, we add 18 to k.

This gives: 18 + k

In the same vein, Jim's number of chirps will reduce by 18.

Initially, Jim had j chirps (or 4k chirps)

To get the new expression, we subtract 18 from j.

This gives: j - 18

So, the equation is:

$j - 18 = 18 +k$

Solving (c): Number of chirps they started with.

In (b), we have:

$j - 18 = 18 +k$

Substitute 4k for j

$4k - 18 = 18 + k$

Collect Like Terms

$4k - k = 18 + 18$

$3k = 36$

Divide both sides by 3

$k =12$

Substitute 12 for k in $j = 4k$

$j = 4 * 12$

$j = 48$
