Answer:

B. Side a is 7 inches long and side b is 6 inches long.

Step-by-step explanation:

Since the scale drawing is three times bigger than the actual object, divide both numbers by three to find the object size.

Side a:

21/3 = 7 inches

Side b:

18/3 = 6 inches

What is the coordinate of the circumference of the circle? Question 2 options: (-3, -1) (1/2, -1/2) (1/2, 0) (0,0)

Norma-Jean [14]

Answer:

The circumcentre of the circle is (0.5,-0.5)

Step-by-step explanation:

Since this is a right triangle, UW is its diameter.

CONCEPT : The angle subtended by the diameter at the circumference of the circle =90°

Hence , center of circle is midpoint of line segment UW.

U(-3,2) and W(4,-3)

Taking the midpoint ,

C( $(\frac{-3 + 4}{2} ,\frac{2-3}{2} )$

Center is C(0.5,-0.5) .

Radius = CV = $\sqrt{(-2.5)^{2}+(-3.5)^{2}}$

R = $\sqrt{\frac{37}{2} }$

Equation of circle is $(x - 0.5)^2 + (y+0.5)^2 = \frac{37}{2}$

The circumcircle of triangle is (0.5,-0.5)

A shape is made of 12 right triangles of equal size each right triangle has a base of 4 centimeters and a height a 5-cm what is

mart [117]

Answer:

$120\ cm^2$

Step-by-step explanation:

The area $(A_t)$ of a triangle is equal to half the product of its length (L) because of its height (h).

$A_t = 0.5h*L$

The base of the triangles is $L = 4\ cm$

The height of the triangles is $h = 5\ cm$

Then the area of one of the triangles is:

$A_t = 0.5(4)(5)\\A_t = 10\ cm^2$

The figure is formed by 12 equal triangles, then the area of the figure $(A_f)$ is:

$A_f = 12(A_t)\\A_f = 12(10)\\A_f = 120\ cm^2$
