Find the total surface area of this square based pyramid. 10 in 5 in

Mathematics
1 answer:
serious [3.7K]3 years ago
8 0

Answer:

125in

Step-by-step explanation:

Each triangular face has a base of 5 in and a height of 10 in. The area of it is given by the formula ...

  A = (1/2)bh

  A = (1/2)(5 in)(10 in) = 25 in²

The square base has an area given by the formula ...

  A = s² . . . . . where s is the side length

  A = (5 in)² = 25 in²

The total area is the sum of the areas of the 4 faces and the base:

  total area = 4 × (area of 1 face) + (area of base)

  total area = 4 × (25 in²) + 25 in²

  total area = 125 in²

What is the equation parallel to 3x+2y=8 that goes through the point 2, -4
Gennadij [26K]

Answer:

The equation of the line would be y = -3/2x - 1

Step-by-step explanation:

In order to find this, we first need to find the slope of the original line. We do this by solving for y.

3x + 2y = 8

2y = -3x + 8

y = -3/2x + 4

Since we know parallel lines have the same slope, we know our new line has a slope of -3/2. We can now use that along with the point in point-slope form to find the equation.

y - y1 = m(x - x1)

y - -4 = -3/2(x - 2)

y + 4 = -3/2x + 3

y = -3/2x - 1

Factor the polynomial:81m+48mn
Anton [14]
To factor this polynomial you will have to first find the GCF of 81 and 48 and its 3.

So then you put 3 out the parentheses. 3(----).

Then you have to see how many times 3 goes into 81m and 48m. It is 27m and 16mn.

So then this is what you get, 3(27m-16mn)

Hope it helps you!!!

Jace measured a line to be 14 inches long. If the actual length of the line is
Phantasy [73]

Answer:

6.87022901%

Step-by-step explanation:

He measured 14 out of 13.1 inches. There is a difference of 0.9 inches when u subtract. He miscalculated by 0.9 out of 13.1. In a calculator you divide .9 by 13.1 you get 0.0687022901. Multiply by 100 to get the percent and round it to your desired decimal place.
