If you climb up 5 flights of stairs will give zero. The correct option is D.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that situations can be represented with an integer​ that, when combined with the opposite of −5​, makes​ 0.

If you climb up 5 flights of stairs it will give the positive value of 5 when it is added to -5 then it will give zero.

Therefore, If you climb up 5 flights of stairs will give zero. The correct option is D.

Answer:

Surface Area = 264π

Volume = 576π

Step-by-step explanation:

in the picture

Answer:

SA= 829.38 Inches² which is 829.38/3.14159 = 264π inch³

V = 110.43 inches³.   which is 110.43/ 3.14159 = 35.15π inch³

Step-by-step explanation:

To find the surface area of cylinder, we calculate two area of circle 2πr² and one area of rectangle 2πrh first, and then add them 2πr²+2πrh.

SA of a cylinder =2πrh+2πr², where π≈3.14159

Radius given is 12/2 = 6 inches

=  2 x π x 6 x 16 + 16  x π6 x 6 ≈ 829.3804 = 829.38 Inches²

Volume = h*π *r^2

V = 16 x π

= 110.43 inches³.

Answer:

The integer that describes the translation from B to B' is (-2,1)

Answer:

awnser B and fbe is 55

Step-by-step explanation:

the entire picture is 180 so cut in half there for 90 ok abfe is 90 so bigger section is always 55 and smaller is 35 ok

If the measure of ∠ABD is 6.2 times greater than the measure of ∠CBD=25° and if ∠ FBE and ∠ EBD are congruent then ∠ FBE =65°.

Given that the measure of ∠ ABD is 6.2 times greater than the measure of ∠ CBD and ∠ FBE and ∠ EBD are congruent.

We are required to find the measure of ∠ CBD and ∠ FBE.

∠ABD=6.2*∠CBD--------1

∠ABD+∠CBD=180°

6.2 ∠CBD+∠CBD=180  (From equation 1)

7.2 ∠CBD=180

∠CBD=180/7.2

∠CBD=25°

∠ABD=6.2*25

=155°

∠ABD=90+∠EBD

155=90+∠EBD

∠EBD=155-90

∠EBD=65°

Because ∠ FBE and ∠ EBD are congruent, ∠ FBE =65°.

Hence if the measure of ∠ABD is 6.2 times greater than the measure of ∠CBD=25° and if ∠ FBE and ∠ EBD are congruent then ∠ FBE =65°.

Chemical change

Explanation:

If two types of matter reacts or are combined and energy is given off, the type of change that might have occurred is a chemical change. A chemical change is one in which a new kind of matter is formed. It is always accompanied by energy changes. The process is not easily reversible. When an exothermic reaction or change occurs, heat is released and it is a typical characteristic of chemical change.

Answer:

60

Step-by-step explanation:

You can kinda think it out by looking at the 9 and 27. Change 9 to 27 by multiplying by 3. So then, multiply 20×3 also.

20:9 is the same as

60:27

Or you can do some auto-pilot algebra, like this:

20/9 = x/27

crossmultiply.

9x = 540

divide by 9

x = 60

When we're solving with scale factors, we either divide or multiply.

If the shape becomes larger, we multiply to get the new length.

If the shape becomes smaller, we divide to get the new length.

We're given:

Because the shape becomes larger, we have to multiply the original side length by the scale factor, 6, to get the new side length.

2.5 x 6 = 15

Therefore, the missing side length is 15 units.

Answer:

252 square yards.

Step-by-step explanation:

To find the square yardage of the roof of the building, we need to calculate the area of the shaded triangle and the area of the shaded rectangle.

First, let's calculate the area of the triangle:

Base of the triangle = 6 divisions = 6 x 2 yards = 12 yards

Height of the triangle = 5 divisions = 5 x 2 yards = 10 yards

Area of the triangle = (1/2) x base x height

= (1/2) x 12 yards x 10 yards

= 60 square yards

Next, let's calculate the area of the rectangle:

Length of the rectangle = 8 divisions = 8 x 2 yards = 16 yards

Width of the rectangle = 6 divisions = 6 x 2 yards = 12 yards

Area of the rectangle = length x width

= 16 yards x 12 yards

= 192 square yards

To find the square yardage of the roof, we add the area of the triangle and the area of the rectangle:

Total area = 60 square yards + 192 square yards

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

Answer:

Both <6 and 7 would be supplementary to <5

Step-by-step explanation:

Supplementary means two angles that add up to 180 degrees, and 180 degrees is a straight line. Taking that into account adding <6 and 5 add up to 180 together. Same with <8 and 5.

Answer:

\(\frac{16}{27}\)

Step-by-step explanation:

From the table, we notice that the total number of students is:

\(3+10+8+6=27\)

Then, along the second column of the table, we notice that the number of students who do not have a brother is:

\(10+6=16\)

So, the probability that a randomly chosen student does not have a brother is:

\(\frac{\text{number of students who do not have a brother}}{\text{total number of students}}=\frac{16}{27}\)

Answer:

x = 10; x = 0

Step-by-step explanation:

x < 29 means x is less than 29. Any number less then 29 is a solution.

For example, pick x = 10. Since 10 < 29, x = 10 is a solution. How do we know x = 10 is a solution?

We start with x < 29.

Now replace x with 10.

10 < 29

Since 10 < 29 is a true statement, then x = 10 is a solution.

Now pick another number less than 29. For example, oick 0.

x = 0 is a solution.

Proof:

x < 29

Replace x with 0:

0 < 29

Since 0 < 29 is a true statement, then x = 0 is a solution.

You can give more solutions just by picking any numbers that are less than 29, such as 1, 2, 3, 15, 28, 23, -5, -18, etc.

Answer: x = 10; x = 0
