I need help finding x

BigorU [14]

Answer:

The answer to your question is x = $\sqrt{50}$ or x = 5 $\sqrt{2}$

Step-by-step explanation:

To solve this problem use the Pythagorean theorem because two right triangles are formed.

c² = a² + b²

c = 10

a = x

b = x Because in a square all the sides measure the same.

10² = x² + x²

- Simplify

100 = 2x²

x² = 100/2

x² = 50

x = $\sqrt{50}$ or x = 5 $\sqrt{2}$

The height of a square pyramid-shaped gift box is one half the length of

Schach [20]

Answer:

15 inches

Step-by-step explanation:

Volume of a squre based pyramid :

V = a²(h/3)

a = base edge ; h = height

h =1/2 a

V = 4500

4500 = a² * (1/2a) ÷ 3

4500 = a² * a/2 * 1/3

4500 = a³/2 * 1/3

4500 = a³ / 6

27000 = a³

Take the cube root of both sides

(27000)⅓ = a

30 = a

Recall:

h = 1/2a

h = 1/2(30)

h = 15 inches

Shiloh has to earn at least $200 to meet her fundraising goal. She has only 100 cakes that she plans to sell at 5 dollars each.

kakasveta [241]

Here is the inequality you can enumerate:

5x >= 200, this means the money you sold for cakes must be larger or equal to your goal

x <= 100, this means you cannot sell more than 100 cakes, because you only have 100 cakes

Solve for them, you will get: 40 <= x <= 100
