Answer:scales percent error=3.51%

Step-by-step explanation:

P ercent error = Experimental value - Theoretical value /Theoretical value  x 100

Theoretical value = 6255 grams

Experimental value ( use of scale ) = 6475grams

Percent error =(6475- 6255)grams / 6255grams x 100

=220/6255 x 100

=3.51%

A cylindrical water tank's height is 48 feet and the diameter is 30 feet. Considering that 1 cubic yard = 202 gallons, how many
solmaris [256]

Answer:

The answer to your question is the letter C. 253712 gallons

Step-by-step explanation:

Data

height = 48 ft

diameter = 30 ft

1 yd³ = 202 gallons

π = 3.14

the number of gallons = ?

Process

1.- Write the formula to calculate the volume of a cylinder.

Volume = πr²h

2.- Calculate the volume

Volume = (3.14)(30/2)²(48)

-Simplification

Volume = (3.14)(225)(48)

-Result

Volume = 33912 ft³

3.- Convert ft³ to yd³

            1 yd³ -------------- 27 ft³

            x       ------------- 33912 ft³

            x = (33912 x 1)/ 27

            x = 33912 / 27

            x = 1256 yd³

4.- Convert yd³ to gallons

          1 yd³ --------------- 202 gallons

   1256 yd³ ---------------  x

          x = (1256 x 202) / 1

         x = 253712 gallons

Lindsay needs to interview a minimum of 15 people for a project in her
VARVARA [1.3K]

The required inequality is p≥9

Step-by-step explanation:

Given condition:

Lindsay needs to interview a minimum of 15 people.

Lindsay completed interviewing 6 people.

To Find:

The possible number of people she still needs to interview to complete her project.

Solution:

Let p be the number of people needed to complete the project.

To complete the project Lindsay needs to interview minimum 15 people.

                                            i.e.p≥ 15

But she has already interviewed 6 people. so, (15-6) = 9

                                            i.e p+6≥15

                                           or, p+6≥15

                                            ∴ p≥9

Hence the inequality that shows the people she still needs to  interview to complete the project is p≥9.

What can be added to -1 so it can be a positive 1?
Tanzania [10]
So represent missing number with x
x means unknown so
x+-1=+1
adding a negative means subtraction
x-1=1
you can do anything to an equation as long as you do it to both sides
add 1 to both sides
x+1-1=1+1
x+0=2
x=2

the number is 2
