C&A Museum has three million visitors per year. Each visitor spends an averageof 1 hour in the museum. What is the average n

Alona [7]

Answer:

1250 visitors per day

Step-by-step explanation:

Number of visitors per year = 3,000,000

Number of days open per year = 300

Number of hours = 9a.m to 5pm = 8 hours

Number of visitors per hour :

Number of visitors per year / (number of days per year * number of hours per day)

3000000 / (300 * 8)

3000000 / 2400

= 1250 visitors per day

Which ordered pairs are solutions to the inequality

Kipish [7]

Answer:

(1,-1)

(7,12)

(5,-3)

Step-by-step explanation:

we know that

If a ordered pair is a solution of the inequality, then the ordered pair must satisfy the inequality

we have

$y-2x \leq -3$

Verify each case

case 1) we have

(1,-1)

substitute the value of x and the value of y in the inequality and then compare the results

$-1-2(1) \leq -3$

$-3 \leq -3$ ----> is true

therefore

The ordered pair is a solution of the inequality

case 2) we have

(7,12)

substitute the value of x and the value of y in the inequality and then compare the results

$12-2(7) \leq -3$

$-12 \leq -3$ ----> is true

therefore

The ordered pair is a solution of the inequality

case 3) we have

(-6,-3)

substitute the value of x and the value of y in the inequality and then compare the results

$-3-2(-6) \leq -3$

$9 \leq -3$ ----> is not true

therefore

The ordered pair is not a solution of the inequality

case 4) we have

(0,-2)

substitute the value of x and the value of y in the inequality and then compare the results

$-2-2(0) \leq -3$

$-2 \leq -3$ ----> is not true

therefore

The ordered pair is not a solution of the inequality

case 5) we have

(5,-3)

substitute the value of x and the value of y in the inequality and then compare the results

$-3-2(5) \leq -3$

$-13 \leq -3$ ----> is true

therefore

The ordered pair is a solution of the inequality

I need help once again!! Did I forget to mention that ur awesome??

Montano1993 [528]

The kite area can be calculated using the formula
a = 1/2 × d₁ × d₂
with d₁ as first diagonal and d₂ as second diagonal

From the question, we know that
d₁ = 9.5 + 9.5
d₁ = 19 in

d₂ = 7 + 12
d₂ = 19 in

Calculate the area by plugging in the numbers into the formula
a = 1/2 × d₁ × d₂
a = 1/2 × 19 × 19
a = 1/2 × 361
a = 180.5

The area of the kite is 180.5 in²
The answer is fourth answer

A box Is filled with 20 pounds of paper, brown paper takes 1/4 of the box.

Natali5045456 [20]

Answer:

The brown paper weighs 80 ounces.

Step-by-step explanation:

Since the brown paper takes up 1/4 of the 20 pounds of paper in the box, there are $\frac{1}{4}*20=5$ pounds of brown paper.

We know that 1 pound = 16 ounces, so 5 pounds of brown paper weighs 5 * 16 = 80 ounces.

The brown paper weighs 80 ounces.
