I attached a picture showing a graph of y<6 and y>=x-6. As you can see, the point (10,5) is in y<6 and y>=x-6.

You can also tell this because y<6 highlights everything with the y value of less than 6. 5 is less than 6, so instantly you can realize that (10,5) is a solution to the system.

Mike and Ken shared some stamps. \frac{1}{5} 5 1 of Ken's stamps were \frac{1}{3} 3 1 of Mike's stamps. If Mike gave Ken 24

Zielflug [23.3K]

Answer:

Mike had 72 stamps

Ken had 120 stamps

Step-by-step explanation:

Given

$M \to Mike$

$K \to Ken$

$\frac{1}{5} * K = \frac{1}{3} * M$

$K + 24 = 3 * ( M - 24)$

Required

Find K and M

Make K the subject in: $K + 24 = 3 * ( M - 24)$

$K = 3 * ( M - 24) - 24$

Substitute $K = 3 * ( M - 24) - 24$ in $\frac{1}{5} * K = \frac{1}{3} * M$

$\frac{1}{5} * [3 * ( M - 24) - 24] = \frac{1}{3} * M$

Open brackets

$\frac{1}{5} * [3M - 72 - 24] = \frac{1}{3} * M$

$\frac{1}{5} * [3M -96] = \frac{1}{3} * M$

Multiply both sides by 15

$3* [3M -96] = 5 * M$

$9M -288 = 5M$

Collect like terms

$9M -5M= 288$

$4M= 288$

Divide both sides by 4

$M= 72$

Substitute $M= 72$ in $K = 3 * ( M - 24) - 24$

$K = 3 * (72 - 24) - 24$

$K = 3 * 48 - 24$

$K = 120$

ANSWER QUICKLY PLEASE!!

Yuki888 [10]

It is 30 degrees. Add 90 and 60 to get 180. Then subtract that from 180, since all triangles interior angles add to 180. You’ll get 30.

What is the height of a cone given it has a volume of 225 cm and a base diameter of<br> 10 cm?

Sphinxa [80]

Answer:

B. 8.6 cm

Step-by-step explanation:

⅓*πr²h = Volume formula of a cone (V)

Volume of cone (V) = 225 cm³

diameter of cone (d) = 10 cm

radius of cone (r) = ½(10) = 5 cm

height (h) = ?

Plug in the values into the equation and solve for h

⅓ × π × 5² × h = 225

⅓ × π × 25 × h = 225

(25π × h)/3 = 225

Multiply both sides by 3

(25π × h)/3 × 3 = 225 × 3

25π × h = 675

Divide both sides by 25π

h = 675/25π

h ≈ 8.6 cm (nearest tenth)
