Answer:

Equation: x=45,000 ÷ 3

Answer: 15,000

Step-by-step explanation:

We know that 2/3 of the pens produced in the factory are black. That means that 1/3 of the pens produced in the factory are blue.

If 45,000 pens are produced, then 1/3 of 45,000 will give us the number of blue pens, or x. Now with our equation, we can start solving.

x = 45,000(1/3) is the same thing as x = 45,000 ÷ 3.

45 ÷ 3 is 15. Now we can just add the zeros back in.

x=15000

Therefore, the number of blue pens, or x, is 15,000.

All the best on your homework!

Answer:

Put the arrow on -1.3.

Step-by-step explanation:

In order to find -1.3, we first have to solve the problem.

-2 - (-0.7)

Since negative - negative = negative, we know our answer is already going to be negative.

Subtract -0.7 from -2, and to make it easier you can do it on a calculator if you want.

First remove the brackets, then turn the negative sign on -0.7 and the minus sign into a plus sign. It will turn into:

-2 + 0.7

When you add, 0.7 to -2, the sum is -1.3.

Therefore you mark the arrow on -1.3

Answer:

Triangle JKL has greater area. The area of triangle JKL is 32 in^2 and area of triangle XYZ is 24 in^2.

Step-by-step explanation:

Area of triangle = 1/2*base*height
For triangle JKL,
Area = 1/2 * 8 * 8 = 32 in^2
For triangle XYZ,
Area = 1/2* 4 * 12 = 24 in^2
Thus, Area of XYZ < Area of JKL

Answer:

7 juniors and 2 coins

Step-by-step explanation:

25% is equal to 25/100 which is 1/4. To find 1/4 of 28 it would be 28/4 which is 7. There are 7 juniors in the program.

5-cent: x

10-cent: y

25-cent: z

5x+10y+25z=320 which is also x+2y=5z=64. You can subsitute y for x+3 because he has 3 more 10-cent than 5-cent. x+x+3+z=23 which is 2x+z=20=z=20-2x.

Substitute

x+2(x+3)+5(20-2x)=64

x+2x+6+100-10x=64

7x=106-64

7x=42

x=6, z=20-2*6=8, z-x=8-6=2

Answer: A 3/4

Step-by-step explanation: this is one of those fractions you need to memorize so if it helps think of it like quarters 1/4=25% 2/4=50% 3/4=75% 4/4=100% or divide 3/4=0.75 and 0.75 as a percent is 75% same rule applies to all fractions

Answer:

A

Step-by-step explanation:

75 percent in decimal form would be 0.75

3/4 = 0.75

so they share the same value

Answer:

The number of fruit bars that people got free at the Beachfront store is 700.

The people in Minnesota and Ohio are 8/10 of the total salespeople. The people in Minnesota are 3/10 of the total salespeople.

Step-by-step explanation:

For the problem about free fruit bars:

The pattern is that 2/3 of the bars that were bought will be free.

To find 2/3, we will first do 1050 ÷ 3 to get 350.

Then we multiply by 2 to get 700.

Therefore, the number of fruit bars that people got free at the Beachfront store is 700.

For the problem about the salespeople:

Counting from the picture, there are 10 total parts. To figure out if a statement is true, confirm with the graph.

ex: Figure out if the statement "the people in Minnesota and Ohio are 8/10 of the total salespeople" is true.

Ohio has 5 parts in the graph. Minnesota has 3 parts in the graph. 5+3=8. Now we put this over 10, the total parts. So, the statement is true.

Answer:

0.32 (rounded to the nearest hundredth)

Step-by-step explanation:

If you have any questions ask me please! :)

Answer:

0.32 km

Step-by-step explanation:

Using the formula r = c / (2 * π), where c = 2 kilometers and π = 3.14, we can calculate the radius as:

r = 2 km / (2 * 3.14)

r = 2 km / 6.28

r = 0.31847133758 km

Rounding this to the nearest hundredth gives:r ≈ 0.32 km

Therefore, the approximate radius of the circle is 0.32 kilometers.
