Write an addition expression and a subtraction expression each with a value of 2.4 x 10^-3

1 answer:

8 0

Well,

You can just add up the numbers to get 2.4.

Example:
$1.0*10^{-3}+1.4*10^{-3}=10^{-3}(1.0+1.4)=2.4*10^{-3}$

In the same way you can make a subtraction problem.

Example:
$5*10^{-3}-2.6*10^{-3}=10^{-3}(5-2.6)=2.4*10^{-3}$

Which equation shows that z is directly proportion to the cube of x and inversely

lozanna [386]

Answer:

z = $\frac{kx^3}{y^2}$

Step-by-step explanation:

Given that z is directly proportional to x³ and inversely proportional to y²

Then the equation relating them is

z = $\frac{kx^3}{y^2}$ ← k is the constant of proportionality

a water sprinkler sends water out in a circular pattern. How many feet away from the sprinkler can it spread water if the area f

andrew11 [14]

Answer:

11 feet

Step-by-step explanation:

Area formed by the watery pattern is 379.94 square feet.

Since the water is being sent out in circular pattern, the maximum distance at which the water is reaching out will be equal to the radius of the circle as the sprinkler is at the center of the circle.

Area of a circle is given as:

$Area=\pi r^{2}\\\\ 379.94 = \pi r^{2}\\\\r^{2}=\frac{379.94}{\pi}\\\\ \text{Using pi equal to 3.14, we get}\\\\ r^{2}=121\\\\ r = 11$

This means the radius of the circular pattern being formed is 11 feet. So the sprinkler can spread the water 11 feet away from it.
