How do you do order of operations step by step?.

Answers

Answer 1

Answer:

                    "Please excuse my dear Aunt Sally or PEMDAS"

____________________________________________________________

Please stands for Parentheses, so we solve everything inside of the parentheses first.

Then, Excuse which is for “Exponents.” We answer that after we answer everything in parentheses.

Multiplication, which is the My, and this happens from left to right.

And then division, which is the “Dear,” which also happens left to right.

And then we have addition and subtraction, which also happens from left to right, and this is “Aunt” and “Sally.”

A submarine is cruising at an elevation of
-250/3 meters below sea level, then
descends another 120% meters into the
sea. What is the new location of the
submarine?……NO LINKS

Answers

Answer:

Step-by-step explanation:

these are two different questions .

first i solve first

position of submarine= -250/3 meters below see level

height descended=120 % of 250/3=120/100 ×(250/3)=300,00/300=100 m

new location=-250/3+(-100)=-650/3 below see level.

2nd question

position of submarine=-250 2/3=-752/3 m below see level

height descended=120 5/8=965/8 m =-965/8 m below see level

new positin=-752/3+(-965/8)=-(6016+2895)/24=-8911/24=-371 7/24m below sesa level.

A cylinder has a base radius of 10m and a height of 18m. What is its volume in cubic m, to the nearest tenths place?

Answers

Based on the question, the volume of the cylinder is approximately 56,520 cubic meters.

What is the cylinder  volume?

The formula for the volume of a cylinder is seen as:

V = πr²h

where

V  = volume

r =  radius of the base

h = height of the cylinder.

Then by Substituting the given values, we will have:

V = π(10m)²(18m)

= π(100m²)(18m)

= 18000π cubic meters

To be able to  find the value to the nearest tenths place, we need to use π ≈ 3.14. hence:

V ≈ 18000 × 3.14

= 56520 cubic meters

Therefore, the volume of the cylinder is about 56,520 cubic meters to the nearest tenths place.

Answer:

65.5 in

Step-by-step explanation:

Ok, the two triangles are similar, since they're both right triangles, the angle in C are congruent, and the third has to be by difference. It means that the distance DC is proportional to 44 inches, on the proportion[tex]x:44 = 11.5:23.5 \rightarrow x= 44\frac{11.5}{23.5} = 21,5 in[/tex] To this we need to add the 44 inches traveled in the first part, to get a total of 65.5 in

Answer:

A.

Step-by-step explanation:

The triangles are similar, so we can estimate that the ratio between them is 1:2 (23.5/11.5~~2). Now we have that 44/2 is 22 and 44+22 is 66. The closest answer to 66 is 65.5, which is A.

33-37 odd *equations only* Help pleaseeee I didn’t even know about this until 20 mins ago

Answers

[33] x = 140° & y = 118°

    The lines are parallel, sso we can tell that y will equal 118° degrees because of corresponding angles. Then for x, we can add the non-adjacent angles together, 118° + 22° = 140°

[35] x = 26° & y = 64°

    x will be 180° - 90° - 64° = 26° because a triangle's angles are equal to 180° and the box represents a 90° angle. y is equal to 64° because the lines are parallel, and if we "flip" one of the triangles around we can see that y and 64° are corresponding angles. (to check, we add 26° + 64° + 90°, and it does equal 180°!)

Answer:

Smaller Angle : 36 degrees

Bigger Angle : 144 degrees

Step-by-step explanation:

So we can name the smaller angle x and the larger one 4x. We can add them and make the answer 180. x+4x=180, 5x=180, x=36

Smaller angle : x=36

Bigger Angle : 4x=36*4=144

Answer:

Angle X = 36

Angle Y = 144

Please give me Branliest

Step-by-step explanation:

Ok, so

X + Y = 180

and

4X = Y

So we substitute

X+4X = 180

5X = 180

X = 36

Now

36 + Y = 180

-36          -36

Y = 144
