Answer:

7 seconds

Step-by-step explanation:

The radius of a sphere-shaped balloon increases at a rate of 2 centimeters (cm) per second.

surface area of the completely inflated balloon is 784 cm²

SA=4r²

784= 4r²

784/4= r²

196 = r²

14cm = r

Yhe radius of the complete inflated balloon is 14cm

If the ball inflate at the rate of 2 cm per seconds

Then it took 14/2 = 7 seconds to inflate fully

The sum of 3x and 1 is greater than-5 and less than or equal to 10
ira [324]

Answer:

x is greater than -2 and less than or equal to 3

Step-by-step explanation:

so the 3x + 1 is greater than -5

so 3x is greater than -6

we divide both sides by 3

then we find out that x is greater than -2

we also know that 3x + 1 is less than or equal to 10

so 3x is less than or equal to 9

we divide both sides by 3

then we find out that x is less or equal to 3

so we can say that x is greater than -2 and less than or equal to 3

Help! I'm so confused
sweet-ann [11.9K]
An integer is like a whole number (28 is an integer).
Irrational means the decimal goes on forever.......and cannot be written as a fraction (0.9857... is irrational).
A number that is not real is the squareroot of a negative, or something times i, or dividing by zero (5/0 is unreal).
A rational number can be written as a fraction (like 8 and 1/7).
