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

The radius of a circle is 2 centimeters. What is the circles circumference?

Salsk061 [2.6K]

Answer: 4π cm or 12.56 cm

Step-by-step explanation: To find the circumference of this circle, start with the formula for the circumference of a circle which is C = 2πr.

Since the radius is 2 centimeters, we can

plug in 2 centimeters for <em>r</em> in the formula.

So we have (2)(π)(2 cm) which is equal to 4π cm.

So the circumference of this circle is 4π cm.

Remember that π is approximately equal to 22/7 or 3.14 so we can estimate the value of the circumference by plugging in 3.14 for π.

So we have (4)(3.14) which is equal to 12.56.

So the circumference of the circle is

approximately equal to 12.56 cm.

$\\ \sf\longmapsto 2x+y=2$

$\\ \sf\longmapsto 2x=2-y$

$\\ \sf\longmapsto x=\dfrac{2-y}{2}\dots(1)$

And

$\\ \sf\longmapsto x+1=y+2$

$\\ \sf\longmapsto x=y+2-1$

$\\ \sf\longmapsto x=y+1$

Put the value

$\\ \sf\longmapsto \dfrac{2-y}{2}=y+1$

$\\ \sf\longmapsto 2-y=2(y+1)$

$\\ \sf\longmapsto 2-y=2y+2$

$\\ \sf\longmapsto 2-2=2y+y$

$\\ \sf\longmapsto 3y=0$

$\\ \sf\longmapsto y=\dfrac{0}{3}$

$\\ \sf\longmapsto y=\infty$

Put in eq(1)

$\\ \sf\longmapsto x=\dfrac{2-y}{2}$

$\\ \sf\longmapsto x=\dfrac{2-\infty}{2}$

$\\ \sf\longmapsto x=\dfrac{2}{2}$

$\\ \sf\longmapsto x=1$

If the coefficient of determination is 0.9, the percentage of variation in the dependent variable explained by the variation in

vagabundo [1.1K]

Answer:

90% of the variation in the dependent variable is explained by the independent variable.

Step-by-step explanation:

We are given the following in the question:

coefficient of determination = 0.9

We have to find the percentage of variation in the dependent variable explained by the variation in the independent variable.

Coefficient of Determination:

The coefficient of determination is a measure that explains and predicts the dependent variable.
It explains the variation in the dependent variable caused by the independent variable.
The coefficient of determination, also known as the R squared value and is obtained by squaring the coefficient of correlation.

$\text{Coefficient of Determination} = R^2 = 0.9 = 0.9\times 100\% = 90\%$

Thus, 90% of the variation in the dependent variable is explained by the independent variable.
