Square

P=4s or perimeter is 4 times a side length

Triangle

P = a + b + c. or perimeter is side 1 plus side 2 plus side 3 (Add all sides)

Circle

perimeter = 2 · π · r Or Perimeter is 2 times pi times the radius

Hexagon

perimeter = 6 · s or perimeter is 6 times the length of a side.

Step-by-step explanation:

1. Perimeter = 2 ( 5+4) = 18 cm

Area = 5 × 4 = 20 cm^2

2. Perimeter = 2 (5+5) = 20 cm

Area = 5 × 5 = 25 cm^2

3. Cups of seed needed per sq. meter = Area of the rectangle backyard

= 6 × 7

= 42 cups of seed

= 2(8+8)

= 32 feet

5. Perimeter of rectangular quilt = 2 (4+6) feet

= 20 feet

6. Area of the room = 9 feet × 8 feet

= 72 feet^2

What is the force of gravity (in Newtons) acting between the Earth and a 100-kg person who is on board the International Space S

ratelena [41]

Answer:

$f_{G}=317877.55 N = 317.8 kN$

Step-by-step explanation:

$f_{G}= (G*m_{1}*m_{2})/r^{2} \\Where:\\f_{G}= force of gravity\\G=gravitational constant= 6.6x10^{-11}m^{3}kg^{-1}s^{-2}\\ m_{1}= earth mass = 5.9x10^{24}kg\\m_{2}=person mass = 100kg\\r= distance between the bodies=350km= 350 000 m$

Perform the indicated operation. X^3+43-49x-7x^2 divides by x^2-49

BaLLatris [955]

Answer:

The quotient is: x-7

and remainder is : -300

Step-by-step explanation:

We need to divide $X^3+43-49x-7x^2$ by $x^2-49$

First arrange the term $X^3+43-49x-7x^2$ in terms of ascending order of x.

Arranging we get:

$x^3 - 7x^2 -49x + 43$ \ $x^2-49$

The division steps are shown in figure attached.

The quotient is: x-7

and remainder is : -300
