Klio2033 [76]

Answer:

59sq meters

Step-by-step explanation:

A=L*W

A/W=L

165/22=7.5

7.5=Length

P=L+L+W+W

7.5+7.5+22+22=59sq meters

A cage holds two litter of rats. One litter comprises one female and five males. The other litter comprises seven females and tw

timurjin [86]

Answer:

The probability that the two rats are from the first litter is 14.28%, and the probability that the two rats are from the second litter is 34.28%.

Step-by-step explanation:

Since a cage holds two litter of rats, and one litter comprises one female and five males, while the other litter comprises seven females and two males, and a random selection of two rats is done, to find the probability that the two rats are from the same litter the following calculation must be performed:

6/15 x 5/14 = 0.1428

9/15 x 8/14 = 0.3428

Therefore, the probability that the two rats are from the first litter is 14.28%, and the probability that the two rats are from the second litter is 34.28%.

Maggie's brother is 7 years younger than twice her age. The sum of their ages is 32.

nika2105 [10]

Answer:

Let M = Maggie's age

B = Brother's age

Then M + B = 32

B = 2M - 7

Then M + 2M - 7 = 32

3M= 39 = 13

M= 13

Maggie is 13.

PLEASE HELP!! Is the answer 50 seconds???

saw5 [17]

Answer:

Guillermo reach his lowest altitude 50 sec after diving and the lowest altitude is -125 m

Step-by-step explanation:

Let

x -----> the time in seconds

y ----> altitude in meters

we have

$g(x)=\frac{1}{20}x(x-100)$

$g(x)=\frac{1}{20}x^{2}-5x$

This is a vertical parabola open upward

The vertex is a minimum

To find out the lowest altitude, find the vertex

Complete the square

Factor the leading coefficient

$g(x)=\frac{1}{20}(x^{2}-100x)$

$g(x)+125=\frac{1}{20}(x^{2}-100x+2,500)$

Rewrite as perfect square

$g(x)+125=\frac{1}{20}(x-50)^{2}$

$g(x)=\frac{1}{20}(x-50)^{2}-125$

The vertex is the point (50,-125)

therefore

Guillermo reach his lowest altitude 50 sec after diving and the lowest altitude is -125 m (below the sea level)
