a band made 8,000 copies of an album they sold 6,280 copies how many copies are left

The number that will be equal to 2 tens 15 ones is 35.

The place values on the left of the decimal point start as ones, tens, hundreds, and so on. The place value on the right of the decimal point starts from the point and goes to the right as tenths, hundredths, and so on. The tens mean multiplied by 10. The tenth means the tenth part of that digit which is that digit divided by 10

We are given multiple number names and asked to add them.

We will call d as ones digit, c as tens digit (it get multiplied by 10), b as hundreds digit etc.

We call e as digit at 10th place (division by 10), f as digit at hundredth place and so on.

To find this problem, it will be easier to split the sentences into multiple parts like this;

1. "2 tens" mean 2 x 10 =20

2. "15 ones" mean 15 x 1= 15

Then, if we add them up it will be;

20+15= 35

The answer to this problem would be 35

Therefore, the number that will be equal to 2 tens 15 ones is 35.

Final answer:

To find how far Ebony walked, multiply her walking rate (3 1/2 miles per hour) by the time walked (1 1/3 hours), resulting in a total distance of 4.665 miles.

Explanation:

The question asks, "Ebony walked at a rate of 3 1/2 miles per hour for 1 1/3 hours. How far did she walk?" To answer this, we need to multiply the rate at which Ebony walked by the time she spent walking. The rate is 3½ (or 3.5) miles per hour, and the time is 1⅓ (or 1.333) hours.

So, the calculation is as follows:

Distance = Rate × Time

Distance = 3.5 miles/hour × 1.333 hours

Distance = 4.665 miles

Therefore, Ebony walked a total of 4.665 miles.

Answer:

5b  

Step-by-step explanation:

Given,

The base area of the prism = base area of the pyramid = b,

Also, the height of the prism = 30 ft,

While, the height of the pyramid = [tex]\frac{\text{height of prism}}{2}[/tex]

[tex]=\frac{30}{2}=15\text{ ft}[/tex]

Now, the volume of the pyramid = [tex]\frac{1}{3}[/tex] × base area × height

[tex]=\frac{1}{3}\times b\times 15[/tex]

[tex]=\frac{15b}{3}[/tex]

= 5b ft²

Hence, THIRD option is correct.

To convert a quadratic function in standard form to vertex form, follow these steps: identify the given equation, find the x-coordinate of the vertex, substitute the x-coordinate to find the y-coordinate, and write the function in vertex form.

To convert a quadratic function in standard form to vertex form, follow these steps:

For example, if the quadratic function is given as 2x² - 8x + 5 = 0, we first find the x-coordinate of the vertex using the formula x = -b/2a as x = -(-8)/(2*2) = 2. Substituting this x-coordinate into the equation, we find the y-coordinate of the vertex as y = 2*(2)² - 8*(2) + 5 = -3. Therefore, the quadratic function in vertex form is y = 2(x-2)² - 3.

Final answer:

The difference between the product of 26.22 and 3.09 and the sum of 3.507, 2.08, 11.5, and 16.712 is 47.2208.

Explanation:

The difference between the product and the sum can be found by first calculating the product of 26.22 and 3.09 and then calculating the sum of 3.507, 2.08, 11.5, and 16.712. Once both of these values are calculated, subtract the sum from the product to find the difference.

To calculate the product of 26.22 and 3.09, you would multiply these two numbers:

26.22 × 3.09 = 81.0198

To calculate the sum of 3.507, 2.08, 11.5, and 16.712, you would add these numbers together:

3.507 + 2.08 + 11.5 + 16.712 = 33.799

Finally, to find the difference, subtract the sum from the product:

81.0198 - 33.799 = 47.2208

The difference between the product of 26.22 and 3.09 and the sum of 3.507, 2.08, 11.5, and 16.712 is 47.2208.

Final answer:

The inequality that represents this situation is: 500 - 40w < 30, where w represents the number of weeks that have passed.

Explanation:

The situation can be represented by the inequality:

500 - 40w < 30

where w represents the number of weeks that have passed.

This inequality states that the amount of money remaining in Kayla's account (500 - 40w) must be less than $30 for her to have to pay a penalty. If Kayla's account falls below $30, she would have to pay a penalty because she does not have enough money to cover her regular expenses.

For example, if we substitute w = 10 into the inequality, we get 500 - (40 × 10) < 30, which simplifies to 100 < 30. Since 100 is not less than 30, Kayla would not have to pay a penalty.

To determine Susan's share of the daycare earnings, the simple equation T + 2T = 225 was solved to give Terry's share as $75. Susan's share, being double Terry's, is therefore $150.

The total earnings of Susan and Terry together: 2x (Terry's share) + Terry's share = 225

Given that the total earnings are 225:

2x (Terry's share) + Terry's share = 225

3x (Terry's share) = 225

Terry's share = 225/3 = 75

Susan's share = 2 x 75 = 150

Therefore, Susan's share is 150.
