Monica has a triangular piece of fabric. The height of the triangle is 27 inches and the triangle's base is 18 inches. Monica sa
Fed [463]
Monica forgot to multiply by 1/2
The area of the fabric is 243 in.2

Explanation:
The formula for the area of a triangle is:
1/2 • base • height

Monica’s error is that she only multuplied the base and height, without multiplying 1/2 also.

The area of the fabric is 243 in.2 because:
1/2 • 18 • 27 = 243

Or you could just divide the wrong area Monica solved (486 in2) by 2. You will also get 243 in.2

Have a nice day! And mark me brainliest please!

You are a space alien. You visit planet Earth and abduct 97 chickens, 47 cows, and 77 humans. Then, you randomly select one Eart
ale4655 [162]

Answer:

there are 97 + 47 + 77 = 221 creatures from Earth in the alien spaceship.

the probability that a human being is chosen at random = 77 / 221 = 0.3484 = 34.84%

the probability that a chicken is chosen at random = 97 / 221 = 0.4389 = 43.89%

the probability of choosing a cow at random = 100% - 34.84% - 43.89% = 21.27%

Please help!! Which of the following is a solution to one of the inequalities graphed below but not a solution to the entire sys
murzikaleks [220]

Answer:

B. (-1,-5)

Step-by-step explanation:

In this graph, the darkest portion represents where the two inequalities intersect with each other. The areas with lighter shading is a solution of one of the inequalities.

From the question we can see that we are looking for which point ends up in the light grey area.

A. (4,-3) White

B. (-1,-5) Light Grey

C. (4,-2) White (This point lies on the inequalities's line. As this line is dotted, the points on it are not included, so this one is white.)

D. (3,1) Dark Grey.

As B is the only one that lies in the light grey area, this is the only correct answer.
