139,799,000‬ square miles of Earth's surface area is covered with water

Step-by-step explanation:

Percentage will be used to calculate the surface area of earth covered by water

Given

Surface area of earth = 196900000 square miles

Percentage of water = 71%

So,

Surface\ area\ covered\ by\ water = 71\%\ of\ 196900000\\= 0.71 * 196900000\\= 139,799,000\ square\ miles

Hence,

139,799,000 square miles of Earth's surface area is covered with water

Keywords: Percentage, surface area

Choose two positive integers a and b, making sure that a<5 and b>80 . The width of a rectangular computer screen is a inch
qwelly [4]

Answer:

Dimensions of the screen are a minimum of 10 inches wide by 8 inches high. The difference between the height and width will be 2 inches

Step-by-step explanation:

Height = H

Width = H + a

Area = Height x Width

b = H * (H + a)

b = H^{2} + aH

H^{2} + aH > 80

H^{2} + aH - 80 > 0

a<5 means 'a' can be a = 1, 2, 3, 4

Solving for H for each option of 'a' will give values of 'H' using the quadratic formula below

H = \frac{-b\±\sqrt{b^{2}-4ac}}{2a}

As 'a' and 'b' must be positive integers, H and W must be positive integers as well,

a = 1, H = 8.46, H = -9.46

a = 2, H = 8, H = -10

a = 3, H = 7.57, H = -10.57

a = 4, H = 7.17, H = -11.17

Based on above possible answers:

a=2, H=8

W = H + a

W = 8 + 2

W = 10

Dimensions of the screen are a minimum of 10 inches wide by 8 inches high. The difference between the height and width will be 2 inches

Write the inverse of the function: f (x) = 2x+3
34kurt

Answer:

y = \frac{x - 3}{2}

Step-by-step explanation:

To find the inverse of a function, simply 'switch' the x and y's and solve for y. y = 2x + 3 becomes x = 2y + 3. Now, solving for y, we get y = \frac{x - 3}{2}.

hope this helped! :)
