Answer:
3240 sq meters
Step-by-step explanation:
Area of garden = 90*60= 5400 square meters.
Flowers grown on = 40%
So, grass grown on = (100 -40)% = 60%
60% of 5400 = 0.6*5400 = 3,240.
So, the area of the garden that is grass = 3,240 square meters
Answer:
Step-by-step explanation:
Rounding to nearest tenth:
i) if number in 100th place is 5,6,7,8 or 9, then add 1 to number in the tenth place and after adding remove all the digits right to it.
EG: 4.567 = 4.6
ii) if number in 100th place is 0,1,2,3 or 4, then write down number in the tenth place as it is and then remove all the digits right to it.
Eg: 4.523 = 4.5
a) 0.32 = 0.3 (b) 3.87 = 3.9 (c)0.709 = 0.7
d) 12.75 = 12.8 (d)12.745 = 12.8 e) 645.059 = 645.1
Alright, let's solve the second one because why not:
Let's then work on getting x by itself:
And that's your answer!
Given:
r = 3.8x10⁵ km = 3.8x10⁸ m, the distance between the earth and moon,
F = 20.46x10²⁵ N, the gravitational force between the earth and the moon,
G = 6.674x10⁻¹¹ m³/(kg-s²), gravitational constant
M = 5.972x10²⁴ kg, the mass of the earth.
Let m = mass of the moon.
Then
F = (G*M*m)/r^2
or
m = (F*r^2)/(G*M)
In SI units,
m = [20.46×10²⁵ * (3.8×10⁸)²]/[6.674×10⁻¹¹ * 5.972×10²⁴]
= 7.4125×10²⁸ kg
Answer: 7.4125x10²⁸ kg
Answer:
(0, 1 )
Step-by-step explanation:
The y- intercept is where the line crosses the y- axis
On the y- axis the x- coordinate of any point is zero
From the table when x = 0 , y = 1
Then y- intercept is (0, 1 )
