Answer:

− 11   Integers

2.45  Rational Number

1      Natural Number ( whole number)

− 11/7   Rational Number

Step-by-step explanation:

Natural numbers are numbers which are positive numbers i.e these do not include negative numbers and can be counted such as 1,2,3,4,5------ .Natural numbers do not include a zero.

Whole numbers are natural numbers but these include a zero e.g 0,1,2,3,4,5------

Integers are whole numbers but can be negative as well.

Rational Numbers are numbers in the form of p/q where q ≠0

− 11   Integers

2.45  Rational Number

1      Natural Number ( whole number)

− 11/7   Rational Number

72 is equal to 80% of a number n. Write and solve and equation to find n. Write the percent as a decimal.
valentina_108 [34]
Well I'm not sure what the answer would be since I'm not that smart but I did get the answer of 90, I did this by dividing 72 by 80 which equals .9 and I multiplied that by 100 and got 90.

A lab technician has to fill the tank given below. <br> Find it’s volume .
wel

Answer:

The volume of the cylinder shown in the figure is 628 cube meters

Step-by-step explanation:

Given figure is about cylinder

The height of the cylinder = h = 8 meters

The radius of the base of cylinder = r = 5 meters

Now, let The volume of cylinder = V m³

So, The volume of cylinder is given as V = \pi×r²×h

where r is the radius of its base

And h is the height of cylinder

The value of  \pi = 3.14

So, V =  \pi × r² × h

Or, V = 3.14 × (5)² × 8

Or, V =  3.14 × 25 × 8

or, V = 628 m³

So, The volume of cylinder = V  = 628 m³

Hence The volume of the cylinder shown in the figure is 628 cube meters  Answer

The parabola y = x² - 4 opens: <br> A.) up <br> B.) down<br> C.) right<br> D.) left
fomenos

Answer:

Up

Step-by-step explanation:

Here the easy rules to remember the orientation of the parabolas are

a) If x is squared it opens up or down. And its coefficient of {x^{2}[tex] is negative it opens down.b) If y is squared it opens side ways right or left. It its coefficient of [tex]y^{2}

Hence in our equation of parabola

y = x^ 2-4

x is squared and its coefficient is positive , hence it opens up towards positive y axis.
