Answer

9/20

Step by Step

I got this by turning the 1/4 into a 5/20 and then turned the 1/5 into a 4/20 and then added from there

5/20+4/20=9/20

You have to turn the fractions denominator into the same number by finding the lowest common denominator.

(7, 5) and (-3, 4) written in slope intercept form

Rom4ik [11]

Answer:

y = x/10 + 43/10

Step-by-step explanation:

y - y1/ x - x1 = y2 - y1/ x2 - x1

y - 4/ x +3 = 5 - 4/7 + 3

y - 4 / x + 3 = 1/10

10(y - 4) = x + 3

10y - 40 = x + 3

10y = x + 43

y = x/10 + 43/10

If A(1,2), B(5,-4) and (-3,2) are the vertices of a triangle, which statement holds true?

Zigmanuir [339]

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The correct option is A.

<h3>What is a triangle?</h3>

A triangle is a three-edged polygon with three vertices. It is a fundamental form in geometry. The sum of all the angles of a triangle is always equal to 180°.

The length of different sides are:

$AB = \sqrt{(5-1)^2+(-4-2)^2} = \sqrt{16+36} = \sqrt{52}\rm\ units$

$BC = \sqrt{(-3-5)^2+(2+4)^2} = \sqrt{64+36} = 10\rm\ units$

$AC = \sqrt{(2-2)^2+(-3-1)^2} = \sqrt{16} = 4\rm\ units$

Since the length of all the sides of the triangle is not equal it is a scalene triangle.

Hence, the correct option is A.

V = (1/4)(π* d² * h)
V = (1/4)(π * 10² * 12) 
V = (1/4)(1200π) 
V = 300π 
[ V ≈ 942 cubic units . . . . . to 3 s.f. ]
