Find the product of 1,398 and 8.

Answer:

4/7 m

Step-by-step explanation:

Joanne has a ribbon 4 m long. He cuts it into 7 equal pieces. How long is each piece of ribbon?

From the above question, we can say that:

7 pieces = 4 m

1 piece = x

Cross Mulitiply

7 × x = 1 × 4

x = 4/7 m

Therefore, the length of each piece of ribbon = 4/7 m

Complete Question:

A cube has a side length of 8 inches. Select all values that represent the cubes volume in cubic inches.

Answer:

8³ or 8 * 8 * 8

Step-by-step explanation:

Given the following data;

Length of sides = 8

Mathematically, the volume of a cube is given by the formula;

Volume of a cube = length * length * length ......equation 1.

Or

Volume = length³ ......equation 2.

From equation 1;

Volume of a cube = 8 * 8 * 8

Volume of a cube = 512 cubic inches.

From equation 2;

Volume of a cube = 8³

Volume of a cube = 512 cubic inches.

Answer:

The answer is 160 cm

Step-by-step explanation:

Square is a quadrilateral which has all its sides equal

Perimeter = 2l +2l

=20 times 2 + 20times 2

=40+40

=80

Wrap 2 times= 80 +80

=160cm

Answer:

Perimeter of triangle= sum of two sides and hypotenuse

Answer:

30 units

Step-by-step explanation:

The perimeter of the triangle is the sum of the two legs, or the shorter sides a and b, and the hypotenuse, the last and longest side, c.

We can already see that side a and b have the lengths of 5 and 12 units.

To find the length of c, use the formula a² + b² = c².

Substitute our a and b values into the formula and solve for c.

a² + b² = c²

5² + 12² = c²

25 + 144 = c²

169 = c²

√169 = √c²

13 = c

The third side is 13 units long.

Now we can add our values for a, b, and c together to find the perimeter.

5 + 12 + 13 = P

30 = P

The perimeter is 30 units.

Good luck ^^

Answer:

Answer:

option A all real numbers

Step-by-step explanation:

domain is the all possible "X" values

and X has all real values

All the real numbers of X are domain and range of piecewise function .

What is piecewise function?

A Piecewise Function is a merge of several functions in a single graph. Each function takes a part of the x axis of the graph.

Graph

Domain: The domain of a piecewise-defined function is the union of its subdomains.

Range :The range of a piecewise-defined function is the union of the ranges of each subfunction over its subdomain.

Now,

Thus  the domain and range of piecewise function is all real numbers .

Answer:

[tex]611\:\text{ft}[/tex]

Step-by-step explanation:

In a right triangle only, the tangent of an angle is equal to its opposite side divided by its adjacent side. In this angle marked as [tex]42^{\circ}[/tex] is actually the same as the angle with point [tex]P[/tex].

Therefore, we can set up the following equation:

[tex]\tan 42^{\circ}=\frac{550}{x}[/tex], where [tex]x[/tex] is the distance from the coast.

Solving, we get:

[tex]x=\frac{550}{\tan 42^{\circ}},\\x\approx610.84\approx \boxed{611\:\text{ft}}[/tex]

Answer:

Principal, P = $23675.90

Step-by-step explanation:

Given the following data;

Interest rate = 2.2 %

Future value = $27000

Time = 6 years

Number of times = 365 days

To find the principal amount, we would use the compound interest formula;

[tex] A = P(1 + \frac{r}{n})^{nt}[/tex]

Where;

A is the future value.

P is the principal or starting amount.

r is annual interest rate.

n is the number of times the interest is compounded in a year.

t is the number of years for the compound interest.

Substituting into the equation, we have;

[tex] 27000 = P*(1 + \frac{0.022}{365})^{365*6}[/tex]

[tex] 27000 = P*(1 + 0.000060)^{2190}[/tex]

[tex] 27000 = P*(1.000060)^{2190}[/tex]

[tex] 27000 = P*(1.1404)[/tex]

[tex] P = \frac {27000}{1.1404} [/tex]

Principal, P = $23675.90

Answer:

No, you can not create a triangle with these three side lengths.

Step-by-step explanation:

According to the Triangle Inequality Theorem, in order for three given lengths to form a triangle, two of the side lengths must add up to be greater than the length of the largest length. 16+37 makes 53, which is equal to the length of the largest side, not greater.

Cost per slice

3.75 / 3 = 1.25

Cost of 4 slices

1.25 * 4 = 5

Answer:

$5

Step-by-step explanation:

First, find how much one slice of pizza costs.

Divide Mario's total by the number of slices he got:

3.75/3

= 1.25

So, one slice of pizza costs $1.25

Add this to his total to find how much his bill will be with one more slice:

3.75 + 1.25

= 5

So, his bill will be $5

Step-by-step explanation:

We use distributive property first to simplify the equation. -3(w)+-3(1)+72=4(w)+4(1)-7. This is equal to -3w-3+7w=4w+4-7. Add common values to get 4w-3=4w-3. Because the equations are the same, this means that the answer is infinitely many solutions.

Answer:

1. 38, 80, 89 and 4. 14, 15, 29

I don't know if there is supposed to be only one, but both of those do not form right triangles.

Step-by-step explanation:

Evaluate all of them and see if they meet the requirements of the Pythagorean Theorem, a² + b² = c².

1. 38, 80, 89

a² + b² = c²

38² + 80² = 89²

1444 + 6400 = 7921

7844 ≠ 7921.

This is an answer because it doesn't satisfy the Pythagorean Theorem.

2. 16, 63, 65

a² + b² = c²

16² + 63² = 65²

256 + 3969 = 4225

4225 = 4225

This isn't the answer because it satisfies the Pythagorean Theorem.

3. 36, 77, 85

a² + b² = c²

36² + 77² = 85²

1296 + 5929 = 7225

7225 = 7225

This isn't the answer because it satisfies the Pythagorean Theorem.

4. 14, 15, 29

a² + b² = c²

14² + 15² = 29²

196 + 225 = 841

421 ≠ 841

This is an answer because it does not satisfy the Pythagorean Theorem.
