the hallway id 440 inches long. 2.5 feet of the hallways length is not carpeted. What is the length, in inches, of the hall that is carpeted

Answers

2.5 feet = 30 inches.

Let L = length not carpeted

L = 400/30

L = 13.3333333333

L = 13.33 inches

Final answer:

To find the carpeted part of the hallway, convert the length of the uncarpeted part from feet to inches by multiplying it by 12. Then subtract this length from the total length of the hall in inches. Hence, the carpeted part of the hallway is 410 inches long.

Explanation:

The subject of the problem is mathematics and it is about converting feet to inches to solve a subtraction problem. There are 12 inches in a foot. So, the uncarpeted part of the hallway, which is 2.5 feet, is 2.5 * 12 = 30 inches.

Now, we subtract the uncarpeted length from the total length of the hallway to find the carpeted length. The hallway is 440 inches long and if we subtract the 30 inches (uncarpeted part) from it, we will find the length of the carpeted part.

So, 440 inches - 30 inches = 410 inches. Hence, the carpeted part of the hallway is 410 inches long.

james bought a cheeseburger, fries, and a drink for dinner. the cheeseburger was three times the price of the fries and the drink and the fries were the same price. if the entire meal was 12.50, what was the price of each item

Answers

Final answer:

The price of the fries and the drink is $2.50, the price of the cheeseburger is $7.50, and the total price of the meal is $12.50.

Explanation:

Let's say the price of the fries is x. According to the given information, the cheeseburger is three times the price of the fries and the drink, and the fries and the drink have the same price.

So, the price of the cheeseburger would be 3x, and the price of the fries and the drink would be x.

Given that the entire meal costs $12.50, we can set up the following equation: x + x + 3x = 12.50.

Simplifying the equation yields 5x = 12.50. Dividing both sides by 5, we find that x = 2.50.

Therefore, the price of the fries and the drink is $2.50, the price of the cheeseburger is $7.50, and the total price of the meal is $12.50.

The three pieces of data are given.
1/4 miles in 2/3 min
1/8 mile in 1/3 min
3/8 mile in 1 min

Each of them can be though of as a division or a fraction.
If you multiply the numerator and denominator of a fraction, you get an equivalent fraction.

Start with 1/4 mile in 2/3 min.
Divide both the distance and time by 2.
You get 1/8 mile in 1/3 min. This is the second piece of data, so the first and second pieces of data are proportional.

Now start with the second piece of data:
1/8 mile in 1/3 min, and multiply both by 3.
You get 3/8 mile in 1 minute. This is the third piece of data.

That means all pieces of data are proportional.

Chang made $247 for 13 hours of work at the same rate,how many hours would he have to work to make $323?

Answers

247 / 13 = 323 / x....247 to 13 hrs = 323 to x hrs
cross multiply
(247)(x) = (323)(13)
247x = 4199
x = 4199 / 247
x = 17 hrs <===

247 / 13 = 19

He makes $19 an hour.

323 / 19 = 17

He will need to work 17 hours to earn $323.

" [tex]\frac{4829}{900} [/tex] "; or, "5[tex] \frac{329}{900} [/tex]" ;
or, write as: "5.366" .
________________________________________________________
Explanation:
__________________________________
Given: " (1 + 0.12 ÷ 12)12 * 1 ÷ 2− 1 ÷ 0.12 ÷ 12 = ? " ;
___________________________________________

First, start with the "parentheses" ;
______________________________
"(1 + 0.12 ÷ 12) = ??

Start with the division: " 0.12 ÷ 12 = 0.01 " .

"(1 + 0.01)" = (1.01) .

We have: "1.01 (12)
Given: " (1.01)12 * 1 ÷ 2 − 1 ÷ 0.12 ÷ 12 = ? " ;

So, 1.01 * 12 = 12 .12 .
______________________
" 12.12 * 1 ÷  2 − 1 ÷ 0.12 ÷ 12 = ? " ;

Note: Using order of operations, treat this problem as:

" [ (12.12 * 1) ÷  2 ] − [ (1 ÷ 0.12) ÷ 12 ] = ? " ;

→ ( 12.12 ÷ 2 ) − (25/3) ÷ 12 ] = ? " ;

→ ( 6.06) − { (25/3) * 1/12) } = ?

→ ( 6.06) − { ( 25* 1) / (3*12) = ?

→ ( 6.06) − { ( 25* 1) / (3*12) = ?

→ ( 6.06) − (25/36) ;

→ 6 [tex] \frac{6}{100} [/tex] − [tex] \frac{25}{36} [/tex]  ;

→ 6 [tex] \frac{3}{50} [/tex] − [tex] \frac{25}{36} [/tex]  ;

Rewrite " 6 [tex] \frac{3}{50} [/tex] " ; as an improper fraction:

→ " 6 [tex] \frac{3}{50}[/tex] " = "[ (50*6) + 3 ] / 50 = [tex] \frac{303}{50} [/tex] ;
__________________________________________
→ 6 [tex] \frac{3}{50} [/tex] − [tex] \frac{25}{36} [/tex] ;

= [tex] \frac{303}{50} [/tex]  − [tex] \frac{25}{36} [/tex] ;

= [tex] \frac{(303*36)-(25*50)}{50*36} = \frac{10,908-1250}{1800}[/tex] ;

= [tex] \frac{9658}{1800}[/tex] ;
_________________________________
→ Divide EACH SIDE of the "fraction" by "2" ; to simplify:

Short Answers:

Answer for part A: Definition of perpendicular
Answer for part B: Right Angle Congruence Theorem
Answer for part C: Reflexive Property of Congruence
Answer for part D: Definition of Midpoint
Answer for part E: [tex]\triangle SXR \cong \triangle TXR[/tex]
Answer for part F: CPCTC

-------------------------------------------------------------

Explanations:

Part A:

We are given that [tex]\overline{RX} \perp \overline{ST}[/tex] which means, in english, "line segment RX is perpendicular to line segment ST"

By the very definition of perpendicular, this means that the two line segments form a right angle. This is visually shown as the red square angle marker for angle RXT. Angle RXS is also a right angle as well.

---------------------
Part B:

The Right Angle Congruence Theorem (aka Right Angle Theorem) is the idea that if we have two right angles, then we know that they are both 90 degrees so they must be congruent to one another.

---------------------
Part C:

Any line segment is congruent to itself. This is because any line segment will have the same length as itself. It seems silly to even mention something so trivial but it helps establish what we need for the proof.

---------------------
Part D:

We are given "X is the midpoint of segment ST" so by definition, X is in the very exact middle of ST. Midpoints cut segments exactly in half. SX is one half while TX is the other half. The two halves are congruent which is why SX = TX

---------------------
Part E:

Writing [tex]\triangle SXR \cong \triangle TXR[/tex] means "triangle SXR is congruent to triangle TXR". These two triangles are the smaller triangles that form when you draw in segment RX

Side Note: SAS stands for "side angle side". The angle must be between the two sides. The pairing RX and RX forms one of the 'S' letters (see part C), while the pairing SX and TX forms the other 'S' (see part D). The angles between the sides are RXS and RXT (see part B).

---------------------
Part F:

CPCTC stands for "Corresponding Parts of Congruent Triangles are Congruent"

It means that if we have two congruent triangles, then the corresponding parts are congruent. Back in part E, we proved the triangles congruent. For this part, we look at the pieces RS and RT (which correspond to one another; they are the hypotenuse of each triangle). They are proven congruent by CPCTC

If CPCTC is an odd concept to think about, then try thinking about something like this: you have two houses which are completely identical in every way. We can say that those two houses are congruent. If the houses are identical, then surely every piece that makes up the house is identical to its corresponding piece to the other house. For example, the front door to each house is both the same size, shape, color, made of the same material, designed in the same pattern, etc. So the two doors are congruent as well.

1/7 x 2/3 in simplest form

Answers

1/7 × 2/3

multiply the numernators

1 × 2 = 2

multiply the denominator
7 x 3 = 21

1/7 × 2/3 = 2/21

the answer is 2/21

Final answer:

To solve 1/7 x 2/3, you multiply the numerators together and the denominators to get 2/21. However, you can simplify the fraction to get your final answer, which is 1/10.

Explanation:

In mathematics, when you are multiplying fractions, you multiply the numerators together and the denominators together. So, in the case of the problem 1/7 x 2/3, you would multiply 1 (the numerator of the first fraction) by 2 (the numerator of the second fraction), and 7 (the denominator of the first fraction) by 3 (the denominator of the second fraction).

This results in 2/21. However, both 2 and 21 are divisible by 2, so we simplify this fraction to get the answer 1/10.

Ratio tables are like proportional relationships (if you know what that is), and you have to do this:
6:9 is related to a:45 we don't know a, but since the prior ratio is related to this one, you simply take 9 times what is 45. The answer is 5, so then you multiply 6 times 5 to get 30. Then keep building off of that. The next problem will be 48, then 72.
The bottom ratios start with 10:15. 15 times 3 is 45 so 10 times 3 is 30. The next one is 100, then 70. Hope this helps, sorry that it's confusing!

there are 156 students in 6 different classrooms. What is the ratio of students that classrooms? If there are 80 boys what is the ratio of boys to girls?

Answers

156-80=numb of girls
numb of girls: 76

Ratio of boys to girls=80:76
=20:19

Ratio of students in classrooms= 156:6
=26:1

(assuming that each classroom has the same number of students)

The easiest way to find out ratios is to divide the total (in this case, students) by the divider (in this case, the classrooms).

156 ÷ 6 = 26

The ratio of students to classrooms is 26 students per classroom, or 26 : 1.

In this case, you need to figure out how many girls there are first.

156 - 80 = 76

Because you don't want to end up with a decimal, you need to find the GCF.

The factors of 76 are: 1, 2, 4, 19, 38, 76
The factors of 80 are: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

Your GCF is 4, which is number you divide your total number of boys and total number of girls by.

80 ÷ 4 = 20
76 ÷ 4 = 19

The simplest ratio of boys to girl is 20 boys for every 19 girls, or 20 : 19
