Answer:

not a solution

Step-by-step explanation:

to determine if (- 10, 5 ) is a solution to the system of inequalities.

substitute the coordinates of the point into the left side of both inequalities and compare the result to the right side.

Both inequalities must be true for the point to be a solution.

2x - y = 2(- 10) - 5 = - 20 - 5 = - 25 < - 7 ← true

x - y = - 10 - 5 = - 15 < - 6 ← false

since both inequalities are not true then (- 10, 5 ) is not a solution

What is the surface area, in square inches, of a sphere with a diameter of 8 in.? and round to the nearest whole number. Enter o
grin007 [14]

Answer:

SA = 201 in^2

Step-by-step explanation:

The formula for surface area of a sphere is

SA = 4pi r^2

We know that the diameter is 8

To find the radius we cut the diameter in half.

r = d/2

r = 8/2 =4

Substitute in what we know.

SA = 4 *pi *4^2

    = 4*pi*16

   = 64*pi

Letting pi = 3.14

  = 200.96 in^2

We want to round to the nearest whole number

SA = 201 in^2

A machine fills Quaker oatmeal containers with 32 oz. of oatmeal. After the containers are filled, another machine weighs them.
4vir4ik [10]

We know that ideally a Quaker oatmeal container should have 32 oz. oatmeal.

We also know that a difference of 0.5 oz. is acceptable, otherwise the container is rejected.

Let the amount of oatmeal actually present in the container be Q

32 - 0.5 < Q < 32 + 0.5

⇒ 31.5 < Q < 32.5

Hence, the equation that represents the highest and lightest acceptable weights is 31.5 < Q < 32.5.
