Answer:

V=23.37\ ft^3

Step-by-step explanation:

Given that,

The perimeter of the base of pyramid, P = 10.7 ft

The height of the pyramid, h = 9.8 ft

We need to find the volume of the pyramid.

The perimeter of square is given by :

4s = 10.7, s is side

s = 2.675 ft

Now the volume of pyramid is given by :

V=\dfrac{lbh}{3}\\\\=\dfrac{2.675^2\times 9.8}{3}\\\\V=23.37\ ft^3

So, the volume of the pyramid is equal to 23.37\ ft^3.

juin [17]

Answer:

1/18

Step-by-step explanation:

there are 12 marbles in the bag

P(choose red) = 2/12 = 1/6

P(choose blue after replacement) = 4/12 = 1/3

P(choose red, then blue with replacement) = (1/6)(1/3) = 1/18

Suppose you spin the spinner and toss a coin. What is the probability of NOT heads and NOT 4? A) 1/8 B) 3/8 C) 5/8 D) 7/8
7nadin3 [17]
I think the answer is B) \frac{3}{8}. You can figure this out by multiplying the possible outcomes of the coin by the spinner (4*2) and find the amount of outcomes that are not what you are looking for (3) and put that over the product. (3/8)

Hope this helps

Rewrite the equation in logarithmic form: 2³= 8
GrogVix [38]

Explanation: The base of the power in the original equation becomes the base of the log. So we have ^{log}2. Next, the exponent in the original equation goes on the other side of the equation and finally, the result in the original equation goes inside the log.

So we have ^{log} 2 8 = 3 which is 2³ = 8 written in logarithmic form.

Answer:

  1. a) 2 and 4; b) 1&2, 2&3, 3&4
  2. x = 16

Step-by-step explanation:

1a. Vertical angles share a vertex and are composed of opposite rays. Here, angles 2 and 4 are vertical angles.

1b. Consecutively numbered angles are adjacent, as are angles 1 and 5. The pairs of interest can be chosen from ...

  1&2, 2&3, 3&4, 4&5, 5&1

__

2. Angles 1 and 3 have the same measure, because they are vertical angles. Then we have ...

  78° = (5x -2)°

  80 = 5x . . . . . . . divide by °, add 2

  16 = x . . . . . . . divide by 5
