a giant pizza box in the shape of a rectangular prism measures 38m times 38m times 0.25m. what is the surface area of the box

2 answers:

6 0

So this box will probably be very flat. Draw it out. There would be 4 surfaces with the surface area of 0.25*38. Which equals 9.5. Multiply that by 4 and it's 38. Now take the bigger surfaces. They will be 38 squared, which is 1444. Multiply that by 2, because there are 2 of those surfaces, and you get 2888. To get the total you add them up: 38+2888=2926. So the answer is 2926 meters squared.

So the surface area of a box has this equation: A = 2 (wl + hl + hw)

w = width = 38
l = length = 38
h = height = 0.25

Plugging in:
A = 2 ((38*38) + (38*0.25) + (38*0.25))
= 2926 square meters

50x+30y= 550 what is x and y

melomori [17]

Answer:

x = 8 and y = 5

Step-by-step explanation:

The question is as following:

what is x and y for the following system of equations:

50x + 30 y = 550 ⇒ (1)

44x + 36 y = 532 ⇒ (2)

Subtract (1) - (2)

∴ 6x - 6y = 18

Divide both sides by 6

∴ x - y = 3

∴ x = 3 + y ⇒ (3)

Substitute with the value of x at (1)

50(3+y) + 30y = 550

Solve for y

150 + 50y + 30y = 550

80y = 550 - 150 = 400

∴ y = 400/80 = 5

Substitute with the value of y at (3)

∴ x = 3 + y = 3 + 5 = 8

So, x = 8 and y = 5

you can buy 8 apples at the quick market for $1.45 you can buy 6 of the same apples at stop and save for $1.22 witch place is be

Nataliya [291]

Answer:

The quick market (8 apples for $1:45)

Step-by-step explanation:

To see how much money it is for a single apple, you divide the price by the number of apples.

$1.45 divided by 8 is $0.18

$1.22 divided by 6 is $0.2

Therefore, you can buy the apples for a cheaper price at the quick market.

katrin2010 [14]

I did the math, which wasn't too hard if you knew how to solve it.

There will be 14 roses, which is worth $28. 14($2)

And finally there will be 17 daisies, which is worth $17. 17($1)

$28+$17=$45

The mayor is interested in finding a 95% confidence interval for the mean number of pounds of trash per person per week that is

Hatshy [7]

Answer:

A. Normal

B. 30.1, 32.9

C. 95, 5

Step-by-step explanation:

A. The sampling distribution follows a normal distribution

Given that the sample size is large, we have that the sample distribution follows a normal distribution according to the central limit theorem

B. The 95% confidence interval is given as follows;

$CI=\bar{x}\pm z \times \dfrac{s}{\sqrt{n}}$

The number of residents in the study, n = 120 residents

The sample mean, $\overline x$ = 31.5 pounds

The standard deviation, s = 7.8 pounds

The z-value for 95% confidence level, z = 1.96

Therefore, we get;

C.I. = 31.5 ± 1.96 × 7.8/√(120)

The 95% C.I. ≈ 30.1 ≤ $\overline x$ ≤ 32.9

Therefore, we have that with 95% confidence, the population mean number of pounds per person per week is between 30.1 and 32.9

C. Therefore, according to the central limit theorem, about 95 percent of the groups of 120 will contain the true population mean number of pounds of trash generated per person per week and about 5 percent will not contain the true population mean number of pounds of trash generated per person per week.

What is the length of the missing leg of a right triangle given a leg of length 8 and a hypotenuse of length 10. Leave your answ

bezimeni [28]

Answer:

Step-by-step explanation:

The hypotenuse will always be equal to "c." You can put "a" or "b" as 8. This gives us a^2 + 8^2 = 10^2 which simplifies to a^2 + 64 = 100. From there, you simplify (subtract 64, giving you a^2 = 36, and then take the square root of a^2 & 36 to get a = 6 (because 6*6 = 36))
