<h2>I'm kind of confused about what you are asking but wouldn't this | be the answer?                                                       V</h2>

Answer: 2 inches per minute

Step-by-step explanation:

This is a fraction equal to

0.14285714285714 inches ÷ 0.071428571428571 minutes

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 0.071428571428571

0.14285714285714 inches ÷ 0.071428571428571

<h3><u>                                                                                  </u></h3>

0.071428571428571 minutes ÷ 0.071428571428571

<h3>=  </h3>

2 inches

<h3><u>              </u></h3>

1 minute

<h3>=  </h3>

2 inches

<h3><u>             </u></h3>

minute

= 2 inches per minute

Can you please help me solve for the area
ycow [4]

Answer:

area is equal to 198 cm^2

Step-by-step explanation:

the height h of the left triangle can be obtained by

Pytagoras theorem:

5^2+h^2=13^2\\25+h^2=169\\h^2=169-25\\h^2=144\\h=\sqrt{144} \\h=12

the, the area of the left triangle is

A_1=\frac{5*12}{2} \\A_1=5*6\\A_1=30

the area of the right triangle is

A_2=\frac{2*12}{2} \\A_2=12

and the area of the rectangle in the middle is

A_3=(13)(12)\\A_3=156

Por tanto, el area total sera

A=A_1+A_2+A_3\\A=30+12+156\\A=198

Bag A contains 3 red balls and 3 blue balls.
dezoksy [38]

Answer:

30% probability that the ball taken from B is red.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

Red ball from urn A:

3/6 = 1/2 probability of getting a red ball from urn A.

Then urn B will have 5 balls, 2 of which are red, so 2/5 probability of getting a red ball.

Blue ball from urn A:

3/6 = 1/2 probability of getting a blue ball from urn A.

Then urn B will have 5 balls, 1 of which is red, so 1/5 probability of getting a red ball.

Total:

p = \frac{1}{2}*\frac{2}{5} + \frac{1}{2}*\frac{1}{5} = \frac{2}{10} + \frac{1}{10} = \frac{3}{10}

3/10 = 0.3 = 30%.

30% probability that the ball taken from B is red.

A rectangular carpet is x+5 feet wide and 3x-2 feet long what is the area in square feet of the carpet in terms of x
siniylev [52]
Formula for area:
Area = Wide x Length

Wide: x + 5
Long: 3x - 2

Area = (x + 5) x (3x - 2)
Area = 3x² - 2x + 15x - 10
Area = (3x² + 13x - 10) square feet
