The lengths of the sides of the base of a right square pyramid are 3 feet, and its slant height is 8 feet. If the sides of the b
8_murik_8 [283]

Answer:

B. 9

Step-by-step explanation:

The base of a right square pyramid is a square, and we know that the lengths of the square are 3. We can calculate the original area of the base as: 3 * 3 = 9 ft squared.

The slant height is the height of the triangular sides of the pyramid. We know that it's 8 feet, and that the base of the triangle shares a side with the square, so b = 3. Knowing that h = 8 and b = 3, we can apply the triangle area formula: (b * h) / 2 = (8 * 3) / 2 = 24/2 = 12 ft squared. However, there are 4 triangles, so we multiply 12 by 4: 12 * 4 = 48 ft squared.

We add 48 to 9 to get the total original surface area: 48 + 9 = 57 ft squared.

Now, however, the sides of the base of the square are increased to 9 ft, so our new area is 9 * 9 = 81 ft squared.

The slant height becomes 24 ft, so our new triangle area is: (24 * 9)/2 = 216/2 = 108 ft squared. We multiply that by 4: 108 * 4 = 432 ft squared.

The new surface area is thus 81 + 432 = 513 ft squared.

To find the factor the original surface area is multiplied by, we divide 513 by 57: 513 / 57 = 9.

Thus, the answer is B, 9.

Hope this helps!

In the figure above, the radius of the inscribed circle is inches (in.). What is the perimeter of square CABD?
elixir [45]

Answer:

perimeter of the square is 32 inches

which agrees with the last answer in your list of options.

Step-by-step explanation:

Notice that the radius of the circle is exactly half of the side of the square, therefore, each side of the square must be 8 inches long.

Then, the perimeter of the square (addition of its four sides) is :

4 x 8 inches = 32 inches

Solve using linear combination. 8x+14y=4 -6x-7y+-10
emmasim [6.3K]

It's best to write the two equations as a vertical column:

8x+14y=4

-6x-7y = -10

Note that if we multiply the 2nd equation by 2, we get -12x - 14y = -20. The reason for wanting this version of the 2nd equation is that its -14y cancels the +14y in the first equation:

-12x - 14y = -20

8x+14y=4

Combine these equations, column by column. We get -4x = -16, which results in x = 4. Now find y by subbing 4 for x in either given equation. If we use the first equation, we get 8(4) + 14y = 4, or 32 + 14y = 4, or 14y = -28. Then y = -2.

The solution to this system of linear equations is thus (4,-2).

Check this result by substitution of these coordinates into -6(4) - 7y = -20:

-24 - 7(-2) = -10. Is this true or not?

-24 + 14 = -10 is true. Thus, (4,-2) is the desired solution.
