Shane works at an electronics store. he earns 13% comission on his sales. Shane's comission this month $780. what are his total. sales for this mounth?

Answers

Answer:

$6000

Step-by-step explanation:

let's find the unit rate first

we know that 780 is 13% of all his sales so what we can do is find the unit rate

780/13=60 so 1% of all the money is $60

Now we just do simple multiplication; 60*100=6000

So the original sale was $6000

Hope this helped, have a good day!

Answer:

6000

Step-by-step explanation:

780/13 = 60 (100)

= 6000

A 90% confidence interval for u using the sample results X = 131.2, s=55 , and n= 50 Round your answer for the point estimate to one decimal place, and your answers for the margin of error and the confidence interval to two decimal places. Margin of error:? 90 Confidence Interval?

Answers

Answer:

131.2 ;

12.8 ;

(118.4, 144)

Step-by-step explanation:

Given :

X = 131.2, s=55 , and n= 50

Point estimate of the mean :

Since, sample size is large (n > 30) ; the sample mean = population mean according to the center limit theorem :

Margin of Error = Zcritical * s / sqrt(n)

Zcritical at 90% = 1.645

Margin of Error : 1.645 * (55 / sqrt(50))

Margin of Error : 1.645 * 7.7781745

Margin of Error = 12.795097

Margin of Error = 12.8

The confidence interval (C.I) :

C.I = x ± margin of error

C. I = 131.2 ± 12.8

(131.2 - 12.8) ; (131.2 + 12.8)

If f(x) = 5x – 2 and g(x) = x+1, find (f = g)(x).
OA. 5x - x-3
B. 5x2 +1
O C. 5x® - X-1
D. 5x4 - 2

Answers

Answer: Choice A) 5x^3 - x - 3

=================================================

Work Shown:

We subtract the two functions like so

(f - g)(x) = f(x) - g(x)

(f - g)(x) = ( 5x^3-2 ) - ( x+1 )

(f - g)(x) = 5x^3 - 2 - x - 1

(f - g)(x) = 5x^3 - x - 3 ..... choice A

Note: be sure to remember to distribute the negative to every term inside (x+1), and not just to the x only.

Suppose that the area of a square lawn is 4x^2 + 16x + 16. What is the length of one side of the lawn?

Answers

Answer:

2x+4

Step-by-step explanation:

remember the formula (a+b)^2=a^2+b^2+2ab

in this case, 4x^2 would be a^2, 16 would be b^2, and 16x would be 2ab

so, the variable a would be 2x and the variable b would be 4

so, you can turn 4x^2+16x+16 into (2x+4)^2

and since the area of a square is (one of its sides)^2, or in this case (2x+4)^2, the length of one side of the lawn will be 2x+4

problems where you have to use the (a+b)^2=a^2+b^2+2ab formula to turn trinomials into binomials squared are very common, so make sure to look out for questions like these and be ready to use this formula

Answers

Answer:

20²-(13²-5² )=y²

400-(169-25)=y²

400-144 =y²

256=y²

y=16

Step-by-step explanation:

In the diagram above is a 2 right angle triangles

the length of such diagrams is found using the pythagoras theorem.

in finding the length of the vertical by pythagoras gives..(13²-5²)^-2=12

This is proportional, true or false? (Proportional means it has an equivalent ratio/constant rate of change/the same rate) (True=yes, it's proportional, false means it is not proportional) y = 12x

Answers

Answer:

Yes/True

Step-by-step explanation:

The given expression is :

y = 12 x

We know that, Proportional means it has an equivalent ratio / constant rate of change / the same rate.

Here,

y ∝ x

12 is the constant of proportionality

Hence, the given expression is proportional.

An architect is making a plan for a new circular playground. If 64 feet is the playground's radius, how much fencing needs to go up to keep the kids in the circle?
100.48 feet
200.96 feet
401.92 feet

Answers

Answer:

209.96

Step-by-step explanation:

we know that the circumference of the circle is equal to

C = [tex]\pi D[/tex]

we have

[tex]D = 64 ft[/tex]

substitute would be

[tex]C = \pi (64) = 64\pi ft[/tex]

assume that [tex]\pi = 3.14[/tex]

64[tex]64\pi = 64 * 3.14 = 200.96 ft[/tex]
