Mrs. Schellhaas spent $14.00 of the $20.00 she has on her Starbucks gift card. Which decimal represents the fraction of the $20.00 she spent
Answer:
0.7 or 70%
Step-by-step explanation:
Step 1 : Find what percent 14 is of 20. Set up an equation to solve for x.
14 = x (20)
Divide by 20 on both sides.
14 divided by 20 = 0.7
So the decimal which represents the fraction of the 20 bucks she spent is 0.7
Bonus step : If you want to find what is 0.7 in percentage form, then simply convert. 70/100 = 70 percent.

Solve for x 4(x + 2) = 3 (x - 2)
Answer:
x = -14
)Step-by-step explanation:
To find the value of x
Transpose
4(x + 2) = 3 (x - 2)
4x + 8 = 3x - 6
4x - 3x = -6 -8
x = -14
we can even cross check
putting the value of x by -14
4(x + 2) = 3 (x - 2)
4 (-14 +2) = 3 (-14 -2)
-56 +8 = -42 -6
-48 = -48
same = same
so CROSS-CHECKED
Answer:
x = -14
Step-by-step explanation:
4(x + 2) = 3 (x - 2)
4x + 8 = 3x - 6
x + 8 = -6
x = -14

which reflection carries parallelogram QRST onto itself?
Step-by-step explanation:
that 180° and 360° clockwise and counterclockwise rotations about this point will carry the parallelogram onto itself.
The parallelogram forms the angle [tex]180[/tex] degree and [tex]360[/tex] degree.
What is the parallelogram?
A parallelogram is a flat shape with four straight, connected sides so that opposite sides are congruent and parallel.
This means a parallelogram is a plane figure, a closed shape, and a quadrilateral.
If we rotate it in clockwise then it covers the angle [tex]180[/tex] degree and [tex]360[/tex] degree whether it is in clockwise or in anticlockwise.
Hence, the parallelogram forms the angle [tex]180[/tex] degree and [tex]360[/tex] degree.

Answer:
Let's take an example.
If you put the value of x as 1, it gives one.
Even if you put 3.997654, it will give 3.997654.
But for any negative real number, it gives the same number but not with it's negative sign. Like if x =-3/7,
It will give 3/7.

What is Q1 for this data set?
{2, 3, 5, 5, 6, 8, 8, 9, 10, 11, 11, 11, 12}
Answer:
Q1 = 5
Step-by-step explanation:
Q1 is the first quartile
Divide the data in half, that will get you Q2 or the second quartile
There are 13 data points so the middle is the 7th data point
2, 3, 5, 5, 6, 8, 8, 9, 10, 11, 11, 11, 12
Take the lower half of the data and divide it in half
There are 6 data points so the middle is between the 3rd and the 4th data point so we average them
2, 3, 5, 5, 6, 8,
(5+5)/2 = 10/2 = 5
The 1st quartile or Q1 = 5
Given y = x + 1 Calculate y if x = 3. y is a natural number

y = x+1
y = 3+1
y= 4
