To make things easier, this solid can be divided in 3 parts:

- the first one is 2in long, 5in wide and 8in tall

- the second one is 2in long, 8in wide and 3in tall

- the third one is just like the first one, so 2in long, 5in wide and 8in tall

In order to find the volume of the solids, we need to multiply their dimensions:

1st: 2.5.8 = 80[tex]in^{3}[/tex]

2nd: 2.8.3 = 48[tex]in^{3}\\[/tex]

Hi! Pls help:
What is the expanded form of this number?

902.604

(9×100)+(2×10)+(6×110)+(4×1100)

(9×100)+(2×1)+(6×110)+(4×1100)

(9×100)+(2×1)+(6×110)+(4×11000)

(9×100)+(2×10)+(6×110)+(4×11000)

Answers

Answer:

(9 × 100) + (2 × 1) + (6 × 0.1) + (4 × 0.001)

Step-by-step explanation:

(9 × 100) + (2 × 10) + (6 × 110) + (4 × 1100) = 900 + 20 + 660 + 4400

900 + 20 + 660 + 4400 = 5980

(9 × 100) + (2 × 1) + (6 × 110) + (4 × 1100) = 900 + 2 + 660 + 4400

900 + 2 + 660 + 4400 = 5962

(9 × 100) + (2 × 1) + (6 × 110) + (4 × 11000) = 900 + 2 + 660 + 44000 = 45562

(9 × 100) + (2 × 10) + (6 × 110) + (4 × 11000) = 900 + 20 + 660 + 44000

900 + 20 + 660 + 44000 = 45580

None of your options work. The answer would be:

(9 × 100) + (2 × 1) + (6 × 0.1) + (4 × 0.001)

900 + 2 + 0.6 + 0.004

902.604

The solution is: the expanded form of this number 902.604 is:

(9 × 100) + (2 × 1) + (6 × 0.1) + (4 × 0.001)

What is multiplication?

In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.

Here, we have,

(9 × 100) + (2 × 10) + (6 × 110) + (4 × 1100) = 900 + 20 + 660 + 4400

900 + 20 + 660 + 4400 = 5980

(9 × 100) + (2 × 1) + (6 × 110) + (4 × 1100) = 900 + 2 + 660 + 4400

900 + 2 + 660 + 4400 = 5962

(9 × 100) + (2 × 1) + (6 × 110) + (4 × 11000) = 900 + 2 + 660 + 44000 = 45562

(9 × 100) + (2 × 10) + (6 × 110) + (4 × 11000) = 900 + 20 + 660 + 44000

900 + 20 + 660 + 44000 = 45580

None of your options work.

The answer would be:

(9 × 100) + (2 × 1) + (6 × 0.1) + (4 × 0.001)

900 + 2 + 0.6 + 0.004

902.604

Hence, The solution is: the expanded form of this number 902.604 is:

(9 × 100) + (2 × 1) + (6 × 0.1) + (4 × 0.001)

Answers

Answer:

the value of x n lengh of pq is 12.6

Answer:

12.6

Step-by-step explanation:

They are similar, so their lengths are the same. Except that The second one is bigger, therefore, you need to find the scale in which it is bigger.

7.2 ÷ 4 = 1.8 (line RS ÷ line LM because they are the correlating sides)

3.6 ÷ 2 = 1.8 (line RQ ÷ line LK because they are the correlating sides)

5.4 ÷ 3 = 1.8 (line SP ÷ line MJ because they are the correlating sides)

This tells us the scale is 1.8. So you just multiply 7 by 1.8 to get 12.6

This can be represented as: y = 1.8

7y = x

7(1.8) = x

12.6 = x

The surface area of the sphere is 192 cm^2
so the radius is ______ cm
and the volume would be _____ cm^3

Answers

Answer:

radius = 3.91 cm; volume = 250.4 cm^3

Step-by-step explanation:

Surface area formula = 4πr^2
Since you have everything except the radius, r, divide the surface area, 192 cm^2, to get the radius.
After you’ve done that, take the radius, 3.91, substitute it into the formula for volume.
Formula for volume is = 4/3πr^3

What is the value of x and y?

Answers

Answer:

x = 5/4

y = 15/16

Step-by-step explanation:

y = 3/4x

5/2 x + 2y = 5

Substitute the first equation into the second equation

5/2x + 2(3/4x) = 5

5/2x + 3/2x = 5

Combine like terms

8/2x = 5

4x = 5

Divide by 4

4x/4 = 5/4

x = 5/4

Now find y

y = 3/4 x = 3/4 ( 5/4) = 15/16

X=5/4
Y=15/16
Those are the values

In the figure d, e, and f are parallel lines. What is the value of x?

Answers

Answer:

x = 150

Step-by-step explanation:

Corresponding angles

180 - 60 = x-30

120 = x-30

150 = x

X=150

Explanation:
You take 180 as a straight line is 180° and you make the equation 180-60=x-30 Then you subtract 180 and 60 which equals 120 then add 30 to both sides and the equation after that should look like 150=X and thats your answer.

180-60=x-30
120=x-30

150=X

In triangle ABC, the length of side AB is 19 inches and the length of side BC is 28 inches. Which of the following could be the length of side AC?
A.
52 inches
B.
7 inches
C.
42 inches
D.
49 inches

Answers

Answer: C) 42 inches

=========================================================

Explanation:

Let's say we have a triangle with sides x,y,z

Also, let's further say we know that x = 19 and y = 28 (from AB and BC respectively).

The third missing side z can't be nailed down to a single number, but we can establish a possible range. That range is

y-x < z < y+x

28-19 < z < 28+19

9 < z < 47

So any number between 9 and 47, excluding both endpoints, will work as a possible side length for the third missing side.

Something like 7 inches is too small, so we rule out choice B. Choice D is ruled out since 49 inches is too big. Same goes for choice A also.

The only thing left is choice C. The 42 is between 9 and 47

In other words, 9 < 42 < 47 is true.

So that's why the third missing side could be 42 inches.

Side note: I'm using a modification of the triangle inequality theorem.

The answer is c which is 42 inches hope this helped

you and 5 of you friends go out to dinner. the total bill is $89. the group also wants to leave a 15% tip. if the total bill and tip are split evenly, approximately, how much will each person pay?

Answers

About $17.05,
Since 89/100= 1% of the total bill= 0.89
0.89*15= the total tip= 13.35
Add the total bill and the tip together would be $102.35,
And then you divide that between the 5 of your friends and you, so
102.35/6 which would equal to $17.0583 (3 repeating) for each person.

Each person would pay $20.47. 15% tip= $13.35 + $89= $102.35/5= 20.47
