(please i had to repost since a bot answered my last questions, waste of my 20 points

Answers

Answer: There are often not more than one or two independent variables tested in an experiment, otherwise it is difficult to determine the influence of each upon the final results. There may be several dependent variables, because manipulating the independent variable can influence many different things.

Two independent variables that could result in a change in the monthly electricity bill are: Physical size of products and Skill level of operators of machines.

Independent Variables

Independent variables are the determining factors that influence how a dependent variable changes.

For example, monthly electricity bill is a dependent variable which is dependent on the following:

Physical size of productsSkill level of operators of machines.Non-production machines utilizing electricity among others.

Therefore, two independent variables that could result in a change in the monthly electricity bill are: Physical size of products and Skill level of operators of machines.

Solve for volume please

Answers

Answer:

35.25

Step-by-step explanation:

brainly please

Answer:

V = 780yd

Step-by-step explanation:

We are given a rectangular prism with 3 different sides of numbers, then are asked to find the volume.

The volume of a rectangular prism is V = lwh

l = 20yd

w = 3.25yd

h = 12yd

All we need to do to find the volume is multiply all the number together :

V = 20yd * 3.25yd * 12yd

V = 65yd * 12yd

V = 780yd

A rectangular prism and its net are shown below. (All lengths are in feet.)

A radar measures the speed of a car at 45 miles per hour. The actual speed of the car is 40 miles per hour what is the percent error in the reading of the radar.

Answers

Answer:45

Step-by-step explanation:

answer: 11.11%

step-by-step explanation:
the radar was off by 5 miles per hour, so we need to find what percent 5 is out of 45. percent of (times) if you don’t know how to find that out.
make the assumption that 45 is 100% because it is the output.
next we represent the value we seek with x. so 100% = 45 and x% = 5.
this gives us the simple pair of equations 100% = 45(1) and x% = 5(2).
then multiplying the equations together like 100%/x% = 45/5.
make it into its reciprocal so x%/100% = 5/45. that comes out to be x= 11.11%
5 is 11.11% of 45 so the radar is off by 11.11%

y = 3x − 8
y = 9x − 11

Part A: Using your own words, explain how to solve the pair of equations graphically. Write the slope and y-intercept for each equation that you will plot on the graph to solve the equations.

Part B: What is the solution to the pair of equations?

Answers

Answer:

A. You would first plot the y intercept.  The first equation would be (0,-8) and the second equation is (0,-11).  Then you would plot the slope.  For the first equation, from (0,-8), you would move up 3 plots and right 1 plot.  For the second equation, from (0,-11), you would move up 9 plots and right 1 plot.

B. The solution to the pair of inequalities is (1/2, -13/2).  That is the intersection and point of the two lines.  You would need to graph the two lines (see part A answer) and then find the intersection.

Answer:

he bought 13 coffee mugs and 8 key chains.

Step-by-step explanation:

How about we solve by simulataneousequation:

consider   coffee mug 'x' and key chain 'y'

there are total 21 items,

x+y = 21

=> x  = 21 - y .........................(i)

and

total cost is $132.50

8.5x + 2.75y = 132.5 .........(ii)

put value of x from eqn (i) into (ii):

8.5 ( 21 -y) + 2.75y = 132.50

=> 178.5 - 8.5y + 2.75y = 132.50

=> -5.75y = -46

 =>y = 8

Put vaklue of y back in (i):

x = 21 - y

=> x = 21 - 8 = 13

thus, x = 13

he bought 13 coffee mugs and 8 key chains.
