Divide: 5 by 1 / 4
please
Answer:
20
Step-by-step explanation:
Make 5 a fraction which would be 5/1
Then make an expression, "5/1 / 1/4"
Then switch and flip meaning make the division sign a multiplication sign and make 1/4 into 4/1.
Your expression should look like 5/1 x 4/1
Then multiply 5 and 4 and you get 20. You do not need to write it as a fraction.

Answer: 4.00, 9.00, 11.00, 4.00
Step-by-step explanation:
When we round, we round from the digit one smaller than the one we're rounding to. In this case, since we're rounding to the dollar, we round from the 10th place. To round, we need to know whether the number we're rounding from is smaller than, equal to, or larger than 5. If the number is smaller than 5, we round down. Larger, and we round up. If the number is equal to 5, we also round up.

Which of the following is NOT a linear function?
Answer:
x^2 + 8 = 64 is not a linear function
Step-by-step explanation:
using the process of elimination and a graphing calculator, you can see that the rest of the functions give you a linear function. therefore, the answer is x^2 + 8 = 64 is not a linear function!! i hope this helps you!! <3
The [tex]x^2 + 8 = 64[/tex] is not the liner function.
The following information regarding the linear function is:
It is the function where the graph is in the straight line. The form in the linear function should be y = a + bx.In this, there is one dependent and one independent variable.Therefore we can conclude that the [tex]x^2 + 8 = 64[/tex] is not the liner function.

Lucien can buy 1 lb of Colombian coffee beans for $4.25 you can buy one pound of French roast coffee beans for $3.75 if he buys one pound mixture of the two kinds of beans for $4 how much of each kind of coffee bean does he buy
Answer:
Colombian coffee bought = 0.5 lbs
French roast coffee beans bought = 0.5 lbs
Step-by-step explanation:
Let Colombian coffee bought = [tex]x[/tex] lbs
Total weight of mixture bought = 1 lbs
Therefore, French roast coffee beans bought = (1 - [tex]x[/tex]) lbs
Price of 1 lb Colombian coffee = $4.25
Price of [tex]x[/tex] lbs of Colombian coffee = $[tex]4.25x[/tex]
Price of 1 lb French roast coffee beans = $3.75
Price of (1 - [tex]x[/tex]) lbs French roast coffee beans = $3.75(1 - [tex]x[/tex])
It is given that total money spent is $4.
As per given statement:
[tex]4.25x+3.75(1-x)=4\\\Rightarrow 0.50x=0.25\\\Rightarrow x=\bold{0.5\ lbs}[/tex]
Colombian coffee bought = 0.5 lbs
French roast coffee beans bought = 0.5 lbs
At Gulfport Electronics, Randy earns a monthly salary of $1500 plus a 5% commission of x, his total monthly sales. If his March earnings total $2500, write and solve an equation that could be used to determine his total monthly sales for the month of March
Answer:
His March Earnings is $20000
Step-by-step explanation:
Given
[tex]Salary = \$1500[/tex]
[tex]Commission = 5\%\ of\ sales[/tex]
[tex]March\ Earnings = \$2500[/tex]
Required
Determine the monthly sales
Represent the monthly sales with x
The march earnings can be determined using:
[tex]March\ Earnings = Salary + Commission[/tex]
[tex]March\ Earnings = Salary + 5\%\ of\ x[/tex]
Substitute values of March Earnings and Salary
[tex]2500 = 1500 + 5\% * x[/tex]
[tex]2500 = 1500 + 0.05 * x[/tex]
[tex]2500 = 1500 + 0.05x[/tex]
Solve for 0.05x
[tex]0.05x = 2500 - 1500[/tex]
[tex]0.05x = 1000[/tex]
Solve for x
[tex]x = 1000/0.05[/tex]
[tex]x = 20000[/tex]
Hence:
His March Earnings is $20000

Step-by-step explanation:
The 53rd ball will be blue. I don't really know how to explain but I'll try.
So there are black, white and blue balls. If you look closer you'll see that the words 'black,white,blue,black, blue were repeated twice. So let's say that the first 5 letters are a set. To get the 50th color, all you have to do is 5 × 10 which is 50 and the 50th term is blue. Just add black(51st), white(52nd) and you'll get the 53rd color to be Blue.

Write and equation to represent the function.
Input(x). 1. 2. 3. 4
Output(y). 8. 19. 30. 41
Answer:
[tex]y=11x-3[/tex]
Step-by-step explanation:
Given ordered pairs:
(1, 8) (2, 19) (3, 30) (4, 41)
As the y is directly proportional to x (y values increase +11 for every +1 increase for the x-values) then the equation will be linear.
Point-slope form of a linear equation: [tex]y-y_1=m(x-x_1)[/tex]
(where [tex]m[/tex] is the slope and [tex](x_1,y_1)[/tex] is a point on the line)
[tex]\textsf{slope }m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Let:
[tex](x_1,y_1)=(1,8)[/tex][tex](x_1,y_2)=(2,19)[/tex][tex]\implies \textsf{slope }m=\dfrac{19-8}{2-1}=11[/tex]
Using point-slope equation with m = 11 and point (1, 8):
[tex]y-y_1=m(x-x_1)[/tex]
[tex]\implies y-8=11(x-1)[/tex]
[tex]\implies y=11x-3[/tex]
what is the solution of the following equation? 2x-5+3x=35
2x - 5 + 3x = 35
simplify
5x - 5 = 35
add 5 to both sides
5x - 5 + 5 = 35 + 5
simplify
5x = 40
divide both sides by 5
5x/5 = 40/5
simplify
x = 8

Answer:
12 edges, 6 faces, and 7 vertices.
▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬
I say 12 edges because there are 12 meeting points, and an open shape.
6 faces because there are 6 highlighted points on what looks like an unfolded shape.
8 vertices because you add 2 to the number of edges and subtract by the number of faces, 6.
What critical value of t* should be used for a 98% confidence interval for the population mean based on a random sample of 25 observations?
A. t* = 2.485
B. t* = 2.492
C. t* = 2.787
D. t* = 2.797
Using a t-distribution calculator, it is found that the critical value of t* for a 98% confidence interval with 25 observations is given by:
B. t* = 2.492
How to find the critical value of the t-distribution?It is found using a calculator, with two inputs, which are given by:
The confidence level.The number of degrees of freedom, which is one less than the sample size.In this problem, we have a confidence level of 98% and 25 - 1 = 24 df, hence the critical value is of t* = 2.492, which means that option B is correct.
