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

Answers

Answer 1

Answer:

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

Step-by-step explanation:

Answer 2

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.

A box contains 6 red marbles, 4 green marbles, 3 blue marbles, and 2 yellow marbles. If Greg chooses one marble at random 300 times, how many times would he expect the marble to be blue?

Answers

Answer:

[tex]60[/tex] times

Step-by-step explanation:

There are [tex]6+4+3+2=15[/tex] marbles in total. Out of those, [tex]3[/tex] are blue, so the probability of pulling a blue marble is [tex]\frac{3}{15}=\frac{1}{5}[/tex]. However, this is only the probability of pulling a blue marble when [tex]1[/tex] marble is pulled at random. Therefore, we can expect a blue marble to be pulled [tex]\frac{1}{5}*300=60[/tex] times if [tex]1[/tex] marble is pulled [tex]300[/tex] times at random. Hope this helps!

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

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

6) Write a system of linear inequalities that is given by the following graph.

Answers

Answer:

The system of inequalities are x - y < 1 and y < - 2 The horizontal line shown in the graph has equation y = - 2 {As it is parallel to x-axis} Now, this line is dotted and the lower portion of the graph is shaded. So, the inequality will be y < - 2 ......... (1) Again, another line is there in the graph which passes through the points (1,0) and (0,-1)So, its equation will be

⇒ y + 1 = x ⇒ x - y = 1 Now, the origin (0,0) is within shaded zone of the inequality and putting x = 0 and y = 0, we get 0 - 0 < 1 So, the equation of the inequality is x - y < 1 {As the line is dotted} Therefore, the system of inequalities are x - y < 1 and y < - 2 (Answer)

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.

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
