If you use the 20% off coupon your total will be $16.80.
+ Purchase Price = $21
- Discount (21 x 20)/100 = $4.20
<span>= Final Price 21 - 4.20 = $16.80
</span>
If you use the $5 dollars off coupon your total will be $16.00.
$21 - $5 = $16.00

The better coupon to use would be the five dollars off coupon because $5 dollars off will be 80 cents less than using the 20% coupon.

21/100 gives you .21 then multiply by 20 to get 4.20$ and the 5$ is 5$ so it is worth more

Firstly, arrange the data.

19 23 26 28 28 30 31 35 38 40 43 46

a) 5 number summary

-min value = 19
- Q1= (26+28/2) = 27
- Q2/ Median = (30+31/2)= 30.5
- Q3= (38+40/2)= 39
- Max value- 46

b) range= max value-min value
∴46-19= 21

c)interquartile range = Q3-Q1
                                  = 39-27
                                  =12

PLEASE HELP!
fenix001 [56]

Answer:

No

Step-by-step explanation:

No because (1,2) falls on the line, and the line is a dotted line, which means that any point on the line is not a solution to the inequality.

A building is in the shape of a square pyramid. Each side of the base is 54 meters long and the height is 260 meters.
choli [55]
Side of the base of the pyramid: s=54 m
Height of the pyramid: h=260 m
Volumen of the building = Volumen of the pyramid = V=?

V=Ab*h/3

Area of the base = Area of a square = Ab=s^2=(54 m)^2→Ab=2,916 m^2

V=(2,916 m^2)*(260 m)/3→V=252,720 <span>m³

Answer: T</span>he volume of the building is 252,720 m³

What is the difference of the fractions? Use the number line to help find the answer.
Doss [256]

Answer:

Option 'b' i.e. -11/20 is the correct option.

Thus,

\frac{1}{5}-\frac{3}{4}=-\frac{11}{20}

Step-by-step explanation:

Given the expression

\frac{1}{5}-\frac{3}{4}

Determining the difference of the fractions

\frac{1}{5}-\frac{3}{4}

The Least Common Multiplier of 5, 4 is 20. Thus, adjust the fractions based on the L.C.M.

\frac{1}{5}-\frac{3}{4}=\frac{4}{20}-\frac{15}{20}

Apply the fraction rule:  \frac{a}{c}-\frac{b}{c}=\frac{a-b}{c}

          =\frac{4-15}{20}

Add the number: 4-15 = -11

           =\frac{-11}{20}

Apply the fraction rule:  \frac{-a}{b}=-\frac{a}{b}

            =-\frac{11}{20}

Please check the attached figure, where the pointing-down arrow is representing the correct answer which is -11/20.

Therefore, option 'b' i.e. -11/20 is the correct option.

Thus,

\frac{1}{5}-\frac{3}{4}=-\frac{11}{20}
