Ratio for the volumes of two similar pyramids, given that the ratio of their edge lengths is 8:3?

1 answer:

6 0

All you have to do is divide the left side of the ratio by 5 and the right side of the ratio by 7. The one that comes out even on both sides is the correct one.

У - 6x = ||<br> -77<br> - 2x-3y=-7

Maksim231197 [3]

Answer:

Step-by-step explanation:

1....y=11+6x

-77-2x+3y=-7

replace y by ..1..

so -77-2x+3(11+6x)=-7

-77-2x+33+18x=-7

-44+16x=-7

16x=37

y=11+6x

replace x by 37/16

y=11+6*37/16

y=199/8

Natasha2012 [34]

Answer:

D.) 12x + 3

Step-by-step explanation: What you have to do, is distribute the 4 inside the parentheses.

6 + 4(3x - 2) + 5

6 + 4(3x) - 4(2) + 5

6 + 12x - 8 + 5 -Now combine your like terms

6 + 12x - 3

12x + 6 - 3

12x + 3

Hope this helps you, and is the right answer.

The probability of event A is 0. 48, the probability of event A and B is 0. 21, and the probability of events A or B is 0. 89. W

Mice21 [21]

Probabilities are used to determine the chances of an event

The probability of event B is 0.62

The probabilities are given as:

$\mathbf{P(A) = 0.48}$

$\mathbf{P(A\ and\ B) = 0.21}$

$\mathbf{P(A\ or\ B) = 0.89}$

To calculate the probability of event B, we make use of the following formula

$\mathbf{P(A\ and\ B) = P(A) + P(B) - P(A\ or\ B)}$

So, we have:

$\mathbf{0.21 = 0.48 + P(B) - 0.89}$

Collect like terms

$\mathbf{P(B)= -0.48 +0.21 + 0.89}$

$\mathbf{P(B)= 0.62}$

Hence, the probability of event B is 0.62
