Jackie made an error when trying to determine the value of the expression.
Here are the steps she used. Describe the error that Jackie made.
2/3 (3/5 - 3/4) + 1/2 ➗ 1/4
Step 1: 2/3 (- 3/20) + 1/2 ➗ 1/4
Step 2: - 1/10 + 1/2 ➗ 1/4
Step 3: - 1/10 + 1/8
Step 4: 1/40

help :,)

Answers

Answer 1

Answer: The real answer is 19/10 or 1 and 9/10

Step-by-step explanation:

Jackie added 1/2 and 1/4 to get 1/8 but in order of operation you have to multiply and divide first . So she should have divided 1/2 by 1/4 and then added that with -1/10 .

Explain how to compare decimals. Use the numbers 6.75 and 6.732 to help you explain this process.

tysm I am struggling

Answers

Answer:

6.75>6.732  

Step-by-step explanation:

We are given that  

6.75 and 6.732  

We have to compare two given decimal numbers.  

First we convert like decimal number  

In 6.75 there are two digits after decimal point.  

In 6.732 , there are three digits after decimal point  

Therefore, we put zero in 6.75 to convert like decimal number

Now, we get  

6.750  

Unit place of both decimal numbers are same and tenth place of both decimal number are same.  

Now, hundredth place of 6.750 is 5 and hundredth place of 6.732 is 3  

5 >3

Therefore, 6.750 is greater than 6.732  

6.75>6.732

to compare these decimals, we first have to turn 6.75 into 6.750, so it has the same place value as 6.732. adding a 0 to the right side of the last digit in the decimal does not change its value. now, we compare them. 6=6, 7=7, 5≠3. since 5 is greater than 3, we know 6.75 is greater than 6.732. this can be written as 6.75>6.732.

The Answer is A

Step-by-step explanation:

First you take 3/8 and 3/5. After that, you put 3/8 over 3/5. To get Miles per Hour, you want to put distance over time. Next you invert and multiply. When you are doing this you want to have it looking like this: [tex]\frac{3}{8}[/tex] * [tex]\frac{5}{3}[/tex]. Finally you multiply the top and the bottom and reduce the fraction.

The answer is n= 7.75.

Step-by-step explanation:

Based on the given conditions, formulate: 5.5+2×X=-10

Rearrange unknown terms to the left side of the equation:2x=-10-5.5

Calculate the sum or difference:2x=-15.5

Divide both sides of the equation by the coefficient of variable:x=-15.5/2

Multiply both the numerator and denominator with the same integer:-155/20

Cross out the common factor:-31/4

get the result:  -7.75

Mr. Samuuel Salesman is paid $125 a month. He also earns $50 for every vacuum he sells.

I need to find an equation, a table, and a graph

Answers

…………..Y=125+ 50x…………

Answer:

earnings = $125 + ($50/vacuum)x

Step-by-step explanation:

This problem is best described by a linear equation whose slope is $50/vacuum and whose y-intercept is $125:

The equation represents the man's total earnings.  The independent variable is x, the number of vacuums he sells.

Thus, earnings = $125 + ($50/vacuum)x.  As before, the y-intercept is $125 and the slope of the line is ($50/vacuum).

Plot a black dot at (0, $125).  Now move 2 units to the right from this dot and from there up by $100 to (2, $225).  Plot this new point.  Then draw a line through the two points you've plotted.

Table:

 x   earnings

----  --------------

 0      $125

  1       $125 + $50 = $175

  2      $125 + $100 = $225

and so on.

Since 60% of the 400 kids want more Library books, all you need to do is:

100% - 60% = 40%

find 40% of 400:

400 x 0.4 = 160

then subtract 160 from 400 to get 60%:

400 - 160 = 240

therefore 240 is your answer! :)

A parabola with no real zeros, a negative leading coefficient, and an odd y-intercept.
pls help!

Answers

Answer:

Step-by-step explanation:

A parabolic graph with no real zeros never touches or crosses the x-axis.  

If the leading coefficient is negative, that tells us that the parabola opens down (and, in this case, that the entire graph is below the x-axis, because there are no real zeros.

If the y-intercept is odd, then the constant term, c, in ax^2 + bx + c, must be a negative, odd integer.

Suppose we say that the vertex of a particular parabola that is described by the above is (-2, -1) and that the y-intercept is -3.  (Note:  this is strictly an example.)  Then the vertex equation of this parabola is obtained from the general vertex equation of a parabola,

y = a(x - h)^2 + k.  Here h = -2 and k = -1, and so the particular parabola is

y = -a(x + 2)^2 - 1, where a is a constant and -a is negative.

In general form, this would be y = -a(x^2 + 4x + 4) - 1, or

                                                   y = -ax^2 - 4ax - 4a -1

and the constant terem (-4a -1) must be an odd negative integer

This is only one of an infinite number of possible equations for the parabola described above.

Answer:

Step-by-step explanation:

Firstly for the the mean you add all the numbers and divide by how many they are.73+88+85+88+99+134+129 and divide it by 7 .

Secondly for the median arrange the numbers numerical form and pick the middle number.

Mode is finding the most common number.

Range subtract the largest number from the smallest number.the best measure is mean because it shows you all you bought and helps in finding the perfect amount
