Find the difference between 8/15 and -2/3. Show all calculations in your final answer.

Answers

Answer 1

Step-by-step explanation:

8/15- (-2/3)

8/15 + 2/3

\( \frac{8 + 5(2)}{15} = \frac{8 + 10}{15} = \frac{18}{15} = \frac{6}{5} \)

Answer 2

Answer:

1.2

Step-by-step explanation:

\(\frac{8}{15} -(-\frac{2}{3})\\ \\\frac{8}{15} -(-\frac{10}{15})\\\\\frac{8}{15} +\frac{10}{15} \\\\\frac{18}{15} =1\frac{3}{15}=1\frac{1}{5}\)

Find the sum of the counting numbers from 1 to 25 inclusive. In other words, if S = 1 + 2 + 3 + ... + 24 + 25, find the value of S.

Answers

Answer:

325

Step-by-step explanation:

You must have heard about Arithmetic Progressions (AP)

Arithmetic progressions are a series of numbers such that every successive number is the sum of a constant number and the previous number.

Our very own counting numbers form AP

For example :-

2 = 1 + 1

3 = 2 + 1

4 = 3 + 1

The number in bold (1) is that constant number which is added to a number to form its successive number.

To find the sum of series forming AP, we use the formula :-

\(sum = \frac{n}{2} \{ a + a _{n} \} \)

here,

n is the number of termsa is the first number of the series an is the last number of the series

So we'll use all this information to find the sum of continuous numbers from 1 to 25 where 1 is the first term(a) and 25 is the last(an).

and n is 25

\(S = \frac{25}{2}\{ 1 +25\} \)

\( = \frac{25 \times 26}{2} \)

\( = 25 \times 13\)

\( = 325\)

So, the value of S comes out to be 325.

Answer:

s= 325

Step by step explanation:

Add all numbers 1 to 25 to get 325.

Margo is wrapping a box that is 7 inches long, 10 inches wide, and 4 inches high. How much wrapping paper will she need to cover the entire box?

Answers

She will need to cover a total of 268 square inches of wrapping paper.

She will need to cover six sides of the box. To calculate the surface area of the box, you'll need to add the area of each side. The formula for surface area is: 2lw + 2lh + 2wh. Plugging in the dimensions of the box, we get:

2(7 x 10) + 2(7 x 4) + 2(10 x 4) = 140 + 56 + 80 = 276

So, she will need 276 square inches of wrapping paper. But since she doesn't need to wrap the bottom of the box, we subtract one of the sides, which gives us a total of 268 square inches of wrapping paper.

To calculate the surface area of the box, you need to add the area of all six sides. The area of each side can be found by multiplying the length by the width.

- The area of the front and back sides is 7 x 4 = 28 square inches each.
- The area of the top and bottom sides is 10 x 4 = 40 square inches each.
- The area of the two side sides is 7 x 10 = 70 square inches each.

So, the total surface area of the box is 2(28) + 2(40) + 2(70) = 56 + 80 + 140 = 276 square inches.

Therefore, Margo will need at least 276 square inches of wrapping paper to cover the entire box.

Answer:280 in

Step-by-step explanation: First we multiply the length by the width and that would be 7 by 10 and we would get 70. Next we multiply the height by the total of (l x w), so 4 x 70 would be 280. Margo needs a total of 280 inches of wrapping paper to cover the entire box. Hope this helps! :)

Drag the tiles to the correct boxes to complete the pairs.Match the pairs of coordinates with the distances

Answers

The pairs of coordinates should be matched with the distances between them should be matched as follows;

Pairs                      Distance                 

(4, 2) and (1, -2)   → 5 units.

(-8, 7) and (2, -3)  → √200 units.

(9, 1) and (1, 9)      → √128 units.

(-2, -6) and (-8, 2)  → 10 units.

How to calculate the distance on coordinates?

Mathematically, the distance between two (2) points that are on a coordinate plane can be calculated by using this formula:

Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

For the ordered pairs (4, 2) and (1, -2), we have;

Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

Distance = √[(1 - 4)² + (-2 - 2)²]

Distance = √[(-3)² + (-4)²]

Distance = √(9 + 16)

Distance = √25

Distance = 5 units.

For the ordered pairs or points (-8, 7) and (2, -3), we have;

Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

Distance = √[(2 + 8)² + (-3 - 7)²]

Distance = √[(10)² + (-10)²]

Distance = √(100 + 100)

Distance = √200 units.

For the ordered pairs or points (9, 1) and (1, 9), we have;

Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

Distance = √[(1 - 9)² + (9 - 1)²]

Distance = √[(-8)² + (8)²]

Distance = √(64 + 64)

Distance = √128 units.

For the ordered pairs or points (-2, -6) and (-8, 2), we have;

Distance = √[(x₂ - x₁)² + (y₂ - y₁)²]

Distance = √[(-8 + 2)² + (2 + 6)²]

Distance = √[(-6)² + (8)²]

Distance = √(36 + 64)

Distance = √100

Distance = 10 units.

Answers

Answer:

[ 2] − | −5 + 7 |

Step-by-step explanation:

Since we know that | −5 + 7 | is an absolute value, we know that the answer will be positive no matter what.

Step 1) Solve. | −5 + 7 | = 2.

Step 2) Find which other absolute value is equal to -2.

After solving [2], − | −5 + 7 | = -2, we know that the answer is choice 2.

We know this because | −5 + 7 | = 2, however, since it is multiplied by (-), it becomes -2. And 2 + (-2) = 0

To solve this problem, we need to simplify each expression and see which one, when added to | −5 + 7 |, will equal zero.

We start by simplifying | −5 + 7 |:

| −5 + 7 | = | 2 | = 2

Now we can simplify each of the answer choices:

[2] | +5 − 7 | = | −2 | = 2
[3] | −( −5 + 7 ) | = | 2 | = 2
[4] | 7 − 5 | = | 2 | = 2

We see that only choice [2], when added to | −5 + 7 |, will equal zero:

2 + (−2) = 0

Therefore, the answer is [2] | +5 − 7 |.
