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.

300 x 400 = 1200 the same as 3 x 4 = 12

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.

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.

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:

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

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

In that system, each branch of government is supposed to provide a check on the other branches to prevent any one branch from consolidating too much power and authority. The system though is not foolproof and sometimes those checks have failed. When that has happened in other countries, it becomes possible for one branch of government, usually the President, to consolidate power and abuse their authority.
