Answer: 54000 cube cm
Step-by-step explanation:
Let h be the height of the box kite,
Also the length of one face = 30 cm,
Hence, the total area of the kite box that is covered by the fabric
= 4 × Area of one face
= 4 × 30 × h
= 120 h
According to the question,
120 h = 7200
h = 60 cm
Hence, the height of the box = 60 cm,
The volume inside the kite = The base area of the box × Its height
= 30² × 60
= 900 × 60
= 54000 cm³
Answer:
2 < x < 5
Step-by-step explanation:
<u>< This symbol means 'less than'</u>. The number you put on its left side is less than the number on its right side.
<u>> This symbol means 'greater than'</u>. The number put on its left is greater than its number on the right.
Think of them like a mouth. Remember the 'open side' wants to eat more.
Translate words to symbols:
'x is less than 5'
x < 5
'x is greater than 2'
x > 2
Put them together. The < and > symbols change directions, but x on the closed side of 5. Keep x on the open side of 2.
2 < x < 5
Don't confuse < and > with ≤ and ≥.
≤ and ≥ mean 'less than OR equal to' and greater than OR equation to'.
Answer:
Median- 31
Mean- 39
Mode- 20
Range-71
Step-by-step explanation:
Median-13, 20, 20, 20, 31, 35, 61, 67, 84
31 one is in the middle, also you have to sort it for least to greatest.
Mean- Add all the number then divide by the numbers there are.
Mode-It has occored the most
Range- sort least to greatest, then subtract the highest number to the lowest
By subtracting 25 from both sides, you get:
AB+CD-25=0
by subtracting CD from both sides, you get;
AB=25-CD
by subtracting AB from both sides, you get:
CD=-AB+25
J = jeans
T = t-shirts
You: 5j + 10t = 140
Friend: 3j + 5t = 79
To use elimination in this problem, multiply the second equation by -2 so that 10t and 5t can cancel out:
5j + 10t = 140
-6j - 10t = -158
We are left with -j = -18 or j = 18
Substitute 18 into any equation. I'll use the first equation:
5(18) + 10t = 140
90 + 10t = 140
10t = 50
t = 5
