1 ) Area of the rectangle:
A = L x W
L = √(2² + 2²) = √8 = 2√2
W = √(6² + 6²) = √72 = 6√2
A = 2√2  x  6√2 = 24 units²
2 ) Area of a triangle:
RQ = 2 + 4 = 6 units
h = 4 units
A = ( 6 * 4 ) / 2 = 12 units²
3 ) The perimeter of Δ ABC:
AB = √(3² + 4²) = √25 = 5 units
BC = √(1² + 1²) = √2 = 1.4 units
AC = √(3² + 4²) = √25 = 5 units
P = 5 + 1.4 + 5 = 11.4 units
4 ) Area of the figure ( approx.):
A ≈ ( 8 * 8) - 6.25 - 8 - 2.5 ≈ 47.25
Answer: C ) 50 ft²
5 ) Area under the curve:
A ≈ 0.5 * 3 + 0.5 * 3.5 + 0.5 * 4 + 0.5 * 4.5 + 0.5 * 5 + 0.5 * 4.5 + 0.5 * 4 +
 + 0.5 * 3 ≈ 0.5 * 31.5 ≈ 15.6
Answer: B ) 15 units²

A 2000 L tank containing 550 L of water is being filled with water at the rate of 75 L per minute from a full 1600 L tank. How l
lara [203]

Answer:

After 7 minutes both the tanks will have the same amount of water.

Step-by-step explanation:

The water is filling in a tank at the rate of 75 L/mins from an initial 550 L of water and water is removing from another tank at the same rate from the initial 1600 L of water.

Let us assume that the same amount of water will be there in both the tanks after t minutes.

Therefore, 550 + 75t = 1600 - 75t

⇒ 150t = 1050

⇒ t = 7

Therefore, after 7 minutes both the tanks will have the same amount of water. (Answer)

ivanzaharov [21]
You could simulate this by allowing the numbers 1-4 to represent a correct answer and the numbers 5-6 to represent an incorrect answer. This would have a 2/3 probability of the question in the simulation being correct.

What is the value of k?
makkiz [27]

For f(x), when x=1, y=1, and when x=2, y=4. Since the graphs are both quadratic, you can assume f(x)=x².

For g(x), when x=2, y=1, and when x=4, y=4. So g(x)=(x²)÷4.

Now it's a given that g(x) is equivalent to f(k*x), so we can say

(x²)/4=(kx)²

4kx²=x²

k=1/4

Latisha works x hours each day. Demetrius works 1 more hour each day than Latisha.
snow_tiger [21]

The expressions that can be used to calculate both numbers of hours Demetrius works in 5-day work week is 5(x + 1)  and 5x + 5

We are being told that Latisha works x hours each day and Demetrius works 1 more hour each day than Latisha.

So,

  • Let the amount of works done by Latisha be = x
  • Then, the amount of works done by Demetrius will be = x + 1

Thus, the both expression that can determine the number of hours Demetrius works in five days is:

= 5(x + 1)  and 5x + 5

This is because if we open the bracket from 5(x+1) and multiply each term in the bracket with 5, we end up having 5x + 5.

  • 5 times open paren x plus 1 close paren and 5 x plus 5 is correct.
