What is the area of the triangle 10 13 12

Mathematics
1 answer:
disa [49]3 years ago
5 0

Answer:

A= 57 sq units

Step-by-step explanation:

To calculate the are area of a triangle we use the Herons formula:

A=√s(s-a)(s-b)(s-c) where a, b and c are the sides of the triangle.

s=(a+b+c)/2

s=(10+13+12)/2

=17.5

A=√[17.5(17.5-10)(17.5-13)(17.5-12)]

A= 57 sq units

Eric was attempting to construct a perpendicular bisector to the segment AB with a
matrenka [14]

Erick just needed to open the compass more to create arcs that have a radius of more than half the length of the segment AB. Option C

<h3>Steps in constructing a perpendicular bisector</h3>

The steps involved in constructing a perpendicular bisector are:

  • Draw a line segment XY of any appropriate length.
  • Take a compass, and with X as the center and with more than half of the line segment XY as width
  • Draw arcs above and below the line segment.
  • Repeat the same step with Y as the center.
  • Label the points of intersection as 'P' and 'Q'

Thus, Erick just needed to open the compass more to create arcs that have a radius of more than half the length of the segment AB. Option C

The complete question

Eric was attempting to construct a perpendicular bisector to the segment AB with a compass and straight edge. Which of the below statements explains what Eric may have done wrong?

a. Eric should have started by putting the compass needle point at the midpoint of the segment AB.

b. On the second step, Eric should have placed the compass needle point where the first arc intersected the segment AB.

c. Erick just needed to open the compass more to create arcs that have a radius of more than half the length of the segment AB.

d. Erick didn’t do anything wrong he just needs to connect the opposite endpoints of each arc to finish the construction.

Sandra bought 30 T-shirts at the clothing store. 20% of the T-shirts were blue and half of the T-shirts were black. How many of
insens350 [35]
So you have 20% of blue and 50% of black.
So you have 70% in total that are both blue and black.
100%- 70%= 30%
So that means 30% were neither blue or black.
Do a proportion
30/100= x/30
30 x 30= 900
900 divided by 100= 9
Answer is 9 shirts are neither blue or black

A shop sells 2 brands of sunflower seeds. Brand A's package is in the shape of a cone with radius 2.5 centimeters and height 10
OleMash [197]

The square prism would contain more seed than the cone because it has a larger volume.

<h3>Volume</h3>

Volume is the amount of space occupied by a three dimensional shape or object.

The volume of cone = (1/3) * π * radius² * height = (1/3) * π * 2.5² * 10 = 65.45 cm³

The volume of square prism =  base² * height = 5² * 2.5 = 62.5 cm³

The square prism would contain more seed than the cone because it has a larger volume.
