Answer:

Scalene Triangle

Step-by-step explanation:

If you mark the points on the graph, all three sides have different lengths and angles, therefor it is a scalene triangle.

It cannot be a right triangke bc there is no right angle, and no obtuse either so that crosses out obtuse as an option as well. In order to be an isoceles triangle it must have two sides of equal length, but it does not.

Answer:

option a

option d

option e

Step-by-step explanation:

option a

$-\frac{8}{11}+( -\frac{3}{4})+( -\frac{1}{4})=-\frac{8}{11}-\frac{3}{4} -\frac{1}{4}$

option d

$-(\frac{8}{11}+\frac{3}{4}+\frac{1}{4})=-\frac{8}{11}-\frac{3}{4} -\frac{1}{4}$

option e

$-\frac{8}{11}-(\frac{3}{4}+\frac{1}{4})=-\frac{8}{11}-\frac{3}{4} -\frac{1}{4}$

For hockey practice, Rosa has to skate around a face off circle five times. The face off circle has a diameter of 9.0m. About ho

SVETLANKA909090 [29]

Answer:

$Distance\ cover\ by\ Rosa = 141.3\ m$

Step-by-step explanation:

Given:

Rosa has to skate around a face off circle five times.

$Distance = 5\times circumfrance\ of\ circle$

Diameter of a circle = 9.0 m

Radius of a circle = $\frac{d}{2} =\frac{9}{2}=4.5\ m$

Solution:

We know that the circumference of a circle.

$C = 2\pi r$

Where;

r = Radius of a circle

Substitute $\pi =3.14\ and\ r = 4.5$ in above equation.

$C = 2\times 3.14\times 4.5$

$C = 28.26\ m$

So, the circumference of the circle is 28.26 m.

Rosa has to skate around a face off circle five times, so Rosa cover 28.26 m 5 times.

$Distance\ cover\ by\ Rosa = 5\times 28.26$

$Distance\ cover\ by\ Rosa = 141.3\ m$

Therefore, the distance cover by Rosa to skate 141.3 m.
