The perimeter of the triangle is 34.2 units

To determine the value of the perimeter, we need to know the following;

The formula that is used for calculating the perimeter of a triangle is expressed as;

P = a + b+ c

Such that a , b and c are the lengths of the sides of the triangle

Then, we have that;

Using the Pythagorean theorem

a² =  81 + 121

a² = 202

a = √202 = 14.2 units

Perimeter = 9  + 11 + 14.2

Add the values

Perimeter = 34.2 units

Answer:

The volume of the cylinder is 367.6 M^3

Step-by-step explanation:

Mathematically, we have the volume of a cylinder calculated as follows;

V = pi * r^2 * h

r is the base radius given as 3 m

h is the height given as 13 m

So, we have the volume as;

V = 22/7 * 3^2 * 13 = 367.6 M^3

Answer:

367.6 m³

Step-by-step explanation:

h=13       r=3                              identify variables

V= πr² h                                  use volume of a cylinder formula

V=π(3)²(13)                            substitute variables into formula

V= 367.56634047                   multiply

V=367.6 m³                            round to the nearest tenths place

Step-by-step explanation:

The computation of the time does Jeremiah arrive at the grocery store is shown below:

She ate dinner at 6:17 pm

She took 25 minutes for cooking

She took 12 minutes to drive home from grocery store

And, the 36 minutes to the grocery store

So, the time at which she arrive is

= 6.17pm - 25 minutes - 12 minutes - 36 minutes

= 6.17pm - 73 minutes

= 5:04 pm

Answer:

Rounding can be referred to as a replacement of a number with another number that is equivalent to it. Rounding can be used to shorten a given number without depriving it of its original value. For example, we have to round 56.89. We can round it as replacing it with 57 which is the closest value to 56.

Rounding numbers isn't that difficult task. In fact, it's quite interesting and easy to do. For rounding, all you are required to do is to figure out which decimal place of the number you want to round off. There are different methods to round off numbers. You can round off numbers to Half Up/Down, Round-Up/Down Round Half to Even/Odd, and So on. Anyhow, here, we are concerned with "To What Place You Want to Round Off a Number". This can be illustrated.

To know how rounding calculator works you just have to understand the way the numbers are rounded off to a particular decimal place. Following is a list of the places to which a number can be rounded off: 1. Ones 2. Tens 3. Hundreds 4. Thousands 5. Ten Thousands 6. Millions 7. Tenths (1 decimal place) 8. Hundredths (2 decimal place) 9. Thousandths ( 3 decimal place) 10. Ten Thousandths (4 decimal place) 11. Hundred Thousandths (5 decimal place) 12. Millionths (6 decimal place)

Answer:

1.) 2.5cm

2.) 1 3/4

3.) 1.6

4.) 4/5

5.) 18.84

Step-by-step explanation:

So the radius is half of the diameter, so the first one would be:

5 ÷ 2 = 2.5

We do the same thing for the next one:

3 1/2 ÷ 2 = 1 3/4

Now we have to go backwards because we have the radius and we're trying to find the diameter:

0.8 x 2 = 1.6

And the next one:

3/5 x 2 = 4/5

Now to find the circumference, we multiply the diameter by pi (3.14)

6 x 3.14 = 18.84

let me know if any of these are wrong

hope this helps:)

Answer:

The first one will be equal 2

Because

[tex] \frac{ - 64}{8} = - 8[/tex]

[tex]x ^{3} = 8 \\ [/tex]

[tex] \sqrt[3]{ - 8} = - 2[/tex]

Answer:

1095.2 cm² is correct (don't forget to say it's cm squared)

624.26 m² is correct                 (ditto)

I'm not 100% sure what the identity of the sets means, you're probably correct though

Step-by-step explanation:

area = 74 x 14.8 = 1095.2 cm²

radius = 28.2/2 = 14.1

area = 3.14(14.1²) = 624.26 m²

The expression which represents seven more than the product of a number and 3 equals 5 is 3w + 7 = 5.

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

A statement expressing the equality of two mathematical expressions is known as an equation.

As per the given,

Product of w and 3 = 3w

7 more then 3w = 3w + 7

It is equal to 5 so,

3w + 7 = 5

3w = 5 - 7

w = -2/3

Hence "The expression which represents seven more than the product of a number and 3 equals 5 is 3w + 7 = 5".

Answer:

f(x) = [x – (4 + √20)][x – (4 – √20]

Step-by-step explanation:

In order to know the function that best describes the given f(x) that best reveals it's minimum or maximum, we need to know solve for x.

x² – 8x – 4 = 0

Using completing the square method

x² – 8x = 4

x² – 8x + 4² = 4 + 4²

(x – 4)² = 20

x = 4 ±√20

Therefore

f(x) = [x – (4 + √20)][x – (4 – √20]

Answer:

Step-by-step explanation:

Convert all numbers to decimals.

8.009 = 8.009

8.7 = 8.7

8.09 = 8.09

8.7082 = 8.7082

Arrange the numbers in ascending order.

8.009 , 8.09 , 8.7 , 8.7082

Answer:

[tex]y = \frac{3}{5}x - 2[/tex]

Step-by-step explanation:

First, find two points that are located on the given line. In this case, we will use the following points:

(-5 , -5) , (0 , -2)

First, find the slope. The slope can be found using the slope formula:

slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

Let:

[tex](x_1 , y_1) = (0 , -2)\\(x_2 , y_2) = (-5 , -5)[/tex]

Plug in the corresponding numbers to the corresponding angles:

m = [tex]\frac{-5 - (-2)}{-5 - 0}[/tex]

Simplify. Combine like terms, and then divide:

m = [tex]\frac{-5 + 2}{-5 - 0} = \frac{-3}{-5} = \frac{3}{5}[/tex]

Plug in [tex]\frac{3}{5}[/tex] into the slope (m), and a point into (x , y) to find the y-intercept:

[tex]y = \frac{3}{5}x + b\\-2 = \frac{3}{5}(0) + b\\-2 = 0 + b\\-2 = b\\b = -2\\[/tex]

Your answer:

[tex]y = \frac{3}{5}x - 2[/tex]

Answer:

substitution method

x = 7

y = 2

Step-by-step explanation:

2x - 2y = 10

x = 7

substitute for x:

2(7) - 2y = 10

14 - 2y = 10

subtract 14 from each side of the equation:

-2y = -4

divide both sides by -2:

y = 2
