Which is the quotient of 17. 51 +3.4?
O A. 5.07
O B. 5.15
OC. 5.21
D. 5.25 HELP THIS ENDS IN 10 MINUTES
Answer:
5.15
Step-by-step explanation:
17.51 / 3.4 = 5.15
Answer and Explanation
5.15 or [tex]\frac{17.51}{3.4}[/tex]__________________________________________________________
We can prove this is the answer by dividing both numbers.
__________________________________________________________
[tex]17.51[/tex] = [tex]\frac{1751}{100}[/tex]
[tex]3.4[/tex] = [tex]\frac{17}{5}[/tex] = [tex]3\ \frac{2}{5}[/tex]
__________________________________________________________
[tex]\frac{1751}{100}[/tex] [tex]\div[/tex] [tex]\frac{17}{5}[/tex] = [tex]?[/tex]
[tex]\frac{17.51}{3.4}[/tex] [tex]or[/tex] [tex]5.15[/tex]__________________________________________________________
So, that means the answer is [tex]5.15[/tex]

Noah's brother sells cars and earns 4.5% commission. He sold a truck for $62,000. How much commission will his brother earn?
Answer:
the commission earn by his brother is $2,790
Step-by-step explanation:
The computation of the commission earn by his brother is as follows
= Selling price of the truck × commission percentage
= $62,000 × 4.5%
= $2,790
Hence, the commission earn by his brother is $2,790
We simply applied the above formula so that the correct value could come
And, the same is to be considered
A rectangular carpet has a perimeter of 244 inches. The length of the carpet is 90 inches more than the width. Determine the dimensions of the carpet by solving the equation 2w+2(w+90)=244, where w represents the carpet width.
Answer:
The dimensions of rectangle are:
Width = 16 inches
Length = 106 inches
Step-by-step explanation:
Perimeter of rectangle = 244 inches
Let Width of rectangle = w
Length of rectangle = w+90
We need to find the dimensions (length and width) of the carpet
The formula used will be: [tex]Perimeter=2(length+width)[/tex]
Putting values and making equation:
[tex]244=2w+2(w+90)\\Solving:\\244=2w+2w+180\\244=4w+180\\Switching\:sides\\4w+180=244\\Subtracting\:180\:from\:both\:sides\\4w=244-180\\4w=64\\Dividing\:both\:sides\:by\:4\\\frac{4w}{4} =\frac{64}{4}\\w=16[/tex]
So, we get w = 16
The width w = 16 inches
Now, finding length = w+ 90 = 16+90 = 106 inches
Therefore the dimensions of rectangle are:
Width = 16 inches
Length = 106 inches
Write the equation for the line can somebody help me and show me how to do it
(NOTE: many questions may ask you to put the equation in a certain format. This answer is assuming you can put it in slope-intercept form.)
Answer:
y= -3x-3
Step-by-step explanation:
1) A handy way to write an equation from a graph is to use the slope-intercept form: y = mx + b. In this format, the "m" represents the slope - or the measure of the steepness of the graph (we'll get more into this in the next step). The "b" represent the y-intercept, or where the point in which the graph hits the y-axis. If you know what the slope and y-intercept is, it is very easy to create an equation!
2) So let's find the slope first. The slope of an equation is represented by [tex]\frac{rise}{run}[/tex] , or the change in the y from each point, going up or down, divided by the change of x, going from left to right. So, knowing this, we can take two points we see the line hit and count the change from the x and y values.
Let's take the points (-1,0) and (0,-3). To find the rise, or the change in y, start from (-1,0) and count how many units it would take vertically to get to (0,-3). If you went down, then be sure to add a negative to the number of units you counted. To find the run, or change in x, do the same and count how many steps it would take horizontally to get to (0,-3) too. If you went left, then be sure to add a negative to the number of units you counted. So, if you did it correctly, you would get -3 as your rise and 1 as your run. Using the [tex]\frac{rise}{run}[/tex] equation, divide -3 by 1 and your slope is -3.3) Now, let's find the y-intercept. This part is much easier: just look at the graph and find the point where the line hits the y-axis. In this case, it's (0,-3).
4) All you have to do now is plug the slope and y-intercept we found into y = mx + b. So, put the slope in the "m" place and remember to put the y-value of the y-intercept into the "b" place.
This should get you y= -3x - 3 as your answer!

Answer:

Step-by-step explanation:

Greetings.
The answer is x > 24.
Explanation:
Solving Inequality is almost the same as equation. However, you have to know one thing about solving an Inequality.
That is whenever you move the negative coefficient of the variable, you have to swap the sign of Inequality.
[tex]-\frac{1}{2}x<-12[/tex]
Reminder that
[tex]-\frac{1}{2}x=-\frac{x}{2}[/tex]
We use negative x above 2 instead (Easier in solving)
[tex]-\frac{x}{2}<-12[/tex]
Then we move 2 to divide -12.
[tex]-x<-12(2)\\-x<-24[/tex]
Because the coefficient for x is in negative. We move -1 to divide -24 as we get 24 (Because negative divide negative = positive)
But remember that "whenever you move the negative coefficient of the variable, you have to swap the sign of Inequality."
So we change from < to > instead.
[tex]x>24[/tex]

A. Graph D
B. Graph B
O C. Graph A
D. Graph C
Answer:B
Step-by-step explanation:
Option B is correct, the inequality y≥-2x-2 is represented in the second graph or graph B.
What is Graph?Graph is a mathematical representation of a network and it describes the relationship between lines and points.
The given inequality is y≥-2x-2
y greater than or equal to minus two times of x minus two.
y≥-2x-2
The line passes through the points (-2, 2) and (0, -2).
As there is given greater than or equal to the line should be solid not dotted.
Greater than or equal to means we have to shade away from the origin.
The second graph satisfy all these properties.
y≥-2x-2 is represented in the second graph.
Hence, the inequality y≥-2x-2 is represented in the second graph.

Step-by-step explanation:
Jada's house is 3 and 2/5 miles from the library. Solve the equation to determine how long it will take her to walk from her house to the library if she walks at a steady speed of 4 miles per hour.
Time = distance / speed
Time = 3 2/5 miles / 4 miles per hour
Time = 17/5 / 4
Time = 17/5 x 1/4 = 17 x 1 / 5 x 4 = 17/20 hours
17/20 hours x 60 minutes per hour = 51 minutes.

What is the coefficients of x4 in the expansion of (1+x)4(1+2x)3.
By the binomial theorem,
(1 + x)⁴ = 1 + 4x + 6x² + 4x³ + x⁴
(1 + 2x)³ = 1 + 6x + 12x² + 8x³
In the expansion of (1 + x)⁴ (1 + 2x)³, we get an x⁴ when multiplying
• x⁴ and 1 to get x⁴;
• 4x³ and 6x to get 24x⁴;
• 6x² and 12x² to get 72x⁴; and
• 4x and 8x³ to get 32x⁴.
Add these up:
x⁴ + 24x⁴ + 72x⁴ + 32x⁴ = 129x⁴
