At a garage sale, a large bin full of DVDs and CDs are being sold. All the DVDs are the same price, and all the CDs are the same price.

Aleah buys 2 DVDs for $6 and 4 CDs for $8. Her friend, Ling, wants to buy 4 DVDs and 2 CDs. How much will Ling have to pay?

Aleah's brother, Pierre, wants to spend $20 on DVDs and CDs. What combination of DVDs and CDs could he buy?

Answers

Step-by-step explanation:

If Aleah buys 2 DVDs for $6 and 2 CDs for $8 we can well assume that the DVDs are $3 dollars each and the CDs are 4 Dollars Each. If ling wants to buy 4 DVDs You would multiply how many DVDs she's buying with the price of the DVDs so (4x3=12) so Ling would have to pay $12 for the DVDs and $8 on the CDs

Pierre wants to spend $20 so with the previous information we can come to the solution that Pierre can buy 4 DVDs and 2 CDs for $20.

Simplify the fraction below.

35/4

Answers

Answer:

8 3/4

Step-by-step explanation:

find the greatest common factor of 35 and 4, which is 1.  Then divide both 35 and 4 by the greatest common factor to get the following simplified fraction: 35/4

If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. You could convert it into a whole number or mixed number fraction. Which would now be 8 3/4

(If its not right let me know so I can rethink my answer)

8.75 as a decimal
8 3/4 as a fraction

Answers

Answer:

3x4=12 is 300x400=1200 but it is not multiplied by 100

Step-by-step explanation:

Answer:

Step-by-step explanation:

Definitely not, although in both cases you are multiplying 3 by 4, obtaining 12.

300 * 400 = 3*4*100*100 = 12*10^4, or 12*10000, or 120000, which is not the same as 12.

Answer:

Area of Shaded Region ≈ 0.23 cm^2

Step-by-step explanation:

Simple Question.

The diameter of the circle is 0.4 m, so the radius = 0.4/2 = 0.2 m.

The area of the circle = πr^2 = π(0.2)^2 = 0.04π

The area of the rectangle = 0.9*0.4 = 0.36

The area of the shaded region = 0.36 - 0.04π (π => 3.14) = 0.36 - 0.1256 = 0.2344 ≈ 0.23 cm^2

Answer:

Step-by-step explanation:

x=[tex]\sqrt{15^{2} -12^{2} }[/tex]

x=9 in.

The Pythagorean theorem is a^2+b^2=c^2

So if we plug in a as 12 and c as 15 we get 144+b^2=225 we then solve to get b^2=81 and so b=9.

In your case, b=x, therefore x=9.

Answers

208 in^2

find the area of each of the parts (4 triangles and 1 square)

all of the triangles have the same area since this is a square pyramid
area of triangle = (base X height)/2
so it would be (8 X 9)/2 = 36

for the square, the area is length X width
so it would be 8 X 8 = 64

add all the areas
36+36+36+36+64 = 208

Answers

Answer:

:)

Step-by-step explanation:

Since his wage is 8.75*63=551.25, we can add up the percentages to get 10+6.2+1.45+4+0.1=21.75%. To get 21.75%, we can move the decimal 2 to the left to get 0.2175. Multiply that by 551.25 to get around 119.9 dollars. If you'd like to calculate the individual taxes, you can apply a similar process to figure that out
