m= y2-y1/x2-x1

m= 1-5/-2-3

m = -4/-5

m = 4/5

Thus the slope is 4/5

HELP ME it's almost due find the length of the diagonals of rectangle QRST

Westkost [7]

Answer:

11.since diagonal are equal of rectangle

QS=RT

4x+6=6x-4

6+4=6x-4x

2x=10

x=10/2

x=5

now

diagonal :4x+6=4*5+6=26

12.

again

QS=RT

9x+12=11x-10

12+10=11x-9x

2x=22

x=11

now

diagonal=9*11+12=99+12=111

WORKSHEET-2

Margarita [4]

Answer:

1. $\frac{C}{D}$ = 3.143

2. Circumference

3. Area of the circle is 3850 $cm^{2}$ .

ii. Circumference of the circle is 220 cm.

Step-by-step explanation:

The area, A, and the circumference, c, of a circle can be determined respectively by:

A = $\pi$ $r^{2}$

C = 2 $\pi$ r

where r is the radius of the circle.

1. the ratio of the circumference and diameter, D, of a circle is:

r = $\frac{D}{2}$

so that,

C = 2 $\pi$ $\frac{D}{2}$

C = $\pi$ D

$\frac{C}{D}$ = $\pi$

= $\frac{22}{7}$

= 3.143

2. The distance around a circular region is known as it's circumference.

3. Given a circle of radius 35 cm, then:

A = $\pi$ $r^{2}$

= $\frac{22}{7}$ x $(35)^{2}$

= $\frac{22}{7}$ x 1225

= 22 x 175

A = 3850

Area of the circle is 3850 $cm^{2}$ .

C = 2 $\pi$ r

= 2 x $\frac{22}{7}$ x 35

= 2 x 22 x 5

= 220

C = 220 cm

Circumference of the circle is 220 cm.
