1) In 365 days, Earth makes = 360 degree
So, In 1 day, It would be: 360/365 = 0.986 degree

2) We know, Ф / 360 * 2πr
0.986/360 * 2 * 3.14 * 93
1 / 365.11 * 584.04
Approx. 1.60 million miles

In short, Your Answer would be 1.60 million miles

3) We know, speed = Distance / Time
Here, distance = 1.60 million miles
Time = 24 hour

Substitute their values,
s = 1.60 / 24
s = 0.067 × 1,000,000
s = 66666.67

In short, Your Answer would be 66666.67 mph

Hope this helps!

Given a scale factor of 23

ankoles [38]

Answer:

scale factor(k)=23

A(x,y)=A'(kx,ky)

Let's do by using this formula

C(9,0)=C'(kx,ky)(here x=9 and y=0)

C(9,0)=(23*9,23*0)

C(9,0)=(207,0)

A(0,3)=A'(kx,ky)(here x=0 and y=3)

A(0,3)=A'(23*0,23*3)

A(0,3)=A'(0,69)

The width and length of a rectangle (in feet)are consecutive odd integers. If the length is increased by 5 feet, the area of the

GenaCL600 [577]

Answer:

Option C is correct.

Step-by-step explanation:

Let x be the original width

then x+2 will be the length (consecutive odd integer)

if length is increased by 5 feet , length will be: (x+2)+5 = x+7

Area = 60 square ft.

Area = length * width

60 = (x+7) *x

60 = x^2 +7x

Rearranging

x^2 + 7x -60 = 0

Solving quadratic equation to find the value of x

using Quadratic formula

$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

a=1, b =7, c=-60

$x=\frac{-7\pm\sqrt{(7)^2-4(1)(-60)}}{2(1)}\\x=\frac{-7\pm\sqrt{49+240}}{2}\\x=\frac{-7\pm\sqrt{289}}{2}\\x=\frac{-7\pm17}{2}\\x=5 \,\, and \,\, x = -12\\$

Since width can be positive so x=5

length of original rectangle = x+2 = 5+2 =7

Area of original rectangle = Length * Width

Area of original rectangle = 5 * 7

Area of original rectangle = 35 ft^2

So, Option C is correct.
