Step-by-step explanation:

Find AC

$\sqrt{65^{2} -16^{2} } = 63$

Substract

63 - AD = 12

Answer:

Determine AC with the pythagorean theorem, then you can find CD by subtracting AD.

with DC and BC, you can find BD. again, with the pythagorean theorem

Find the volume of the pyramid below. Hint: The base is a right triangle, so you will need to find

Aleks04 [339]

Given:

Given that the height of the pyramid is 12 units.

The base of the triangle is 8 units.

The height of the triangle is 6 units.

We need to determine the volume of the pyramid.

Area of the triangle:

The area of the triangle can be determined using the formula,

$A=\frac{1}{2} bh$

where b is the base of the triangle and h is the height of the triangle.

Substituting the values, we get;

$A=\frac{1}{2}(8)(6)$

$A=\frac{1}{2}(48)$

$A=24$

Thus, the area of the triangle is 24 square units.

Volume of the pyramid:

The volume of the pyramid can be determined using the formula,

$V=\frac{1}{3}AH$

where A is the area of the triangle and H is the height of the pyramid.

Substituting the values, we get;

$V=\frac{1}{3}(24)(12)$

$V=\frac{1}{3}(288)$

$V=96$

Thus, the volume of the pyramid is 96 cubic units.

There are 19 animals on the farm which contains hens and goats. There are 68 legs in total. How many goats are there on the farm

Masteriza [31]

Answer: 15 goats

Step-by-step explanation:

h = hens - they have 2 legs

g = goats - they have 4 legs

The equations would be:

h + g = 19

2h + 4g = 68

To solve this, I personally prefer substitution, we're isolating h since we need to find g:

h + g = 19

h = 19 - g

Now that we have h, we can plug this into the second equation:

2h + 4g = 68

2(19 - g) + 4g = 68

38 - 2g + 4g = 68

2g = 30

g = 15

There are 15 goats.

Adding onto this, 19 - 15 = 4, so there are 4 hens.
