Answer:
cube root of 123 (approx 4.97)
Step-by-step explanation:
volume of a cube is LxWxH, and since it is a cube, all measurements are equal
The height of the box is 4.973 inch whose volume is 123 cubic inches.
It is given that the volume of a box is 123 cubic inches.
It is required to find the height of the box.
What is volume?It is defined as a three-dimensional space enclosed by an object or thing.
We have:
Volume of a box = 123 cubic inches
Here we are assuming the box is a shape of cube.
We know that the volume of a cube:
[tex]\rm V= a^3[/tex] where a is the side of cube
In the cube all the dimensions are same.
Now,
[tex]\rm 123 =a^3 \ \ or \\\\ a = \sqrt[3]{123}[/tex](∵ V = 123)
a = 4.973 inch
Since in the cube all the dimensions are same, therefore
The height of the cube = 4.973 in
Thus, the height of the box is 4.973 inch whose volume is 123 cubic inches.

Step-by-step explanation:
- 8x -3(4x-y)+7y
First distribute,
-3(4x)= -12x
-3(-y)= y

x=127°y=53°Step-by-step explanation:
to understand thisyou need to know about:polygontips and formulas:sum of any polygon interior angles:(n-2)×180°the given shape is a heptagona line contains 180°let's solvestep-1: find the sum of the polygon interior angles
=(7-2)×180°
=5×180°
=900°
step-2: find x
according to the question
113+112+123+168+99+148+x=900
=>773+x=900
=>x=900-773
therefore
x=127
according to the question
127+y=180
=>y=180-127
therefore
y=53

The first buses to X and Y leave a bus station at 7 am
Buses to X leave every 25 minutes.
Buses to Y leave every 20 minutes.
When will the buses to X and Y next leave at the same time?
Multiples of a number are the numbers that a number can be divided by without any remainder.
The buses X and Y will leave at the same time by 8:40 am
To calculate when buses X and Y will leave at the time, we would have to find the Lowest Common Multiple of 20 and 25 minutes.
Find and list multiple until the first common multiple is found. This is the lowest common multiple.
Multiples of 20:
20, 40, 60, 80, 100, 120, 140
Multiples of 25:
25, 50, 75, 100, 125, 150
Therefore,
LCM(20, 25) = 100
The LCM is 100 minutes
Converting 100 minutes
60 minutes = 1 hour
100 minutes = ?
Cross Multiply
100 minutes x 1 hour / 60 minutes
= 1 2/3 hours.
This can be rewritten as :
= 1 hr 40 minutes
Adding this to 7am
7 am + 1 hr 40 minutes = 8 : 40am
Therefore, the buses X and Y will leave at the same time by 8:40 am

Step-by-step explanation:
Bruno is a manager at a factory that makes in-line skates. The
equation 200x – y + 500 = 0 relates y, the number of pairs of
skates the factory has in the warehouse and x, the number of
hours after Bruno starts his shift.
Show that the equation is a linear equation by writing
it in slope-intercept form. Show your work.
Answer:
Slope- intercept form y = 200 x + 500
Step-by-step explanation:
Given that the equation
200x - y + 500 = 0
where y, the number of pairs of skates the factory has in the warehouse, and x be the number of hours
The slope-intercept form
y = m x +C
Given equation 200x - y + 500 = 0
200 x + 500 =y
y = 200 x + 500
Slope of the equation m = 200 and y-intercept 'C' = 500

What dose 3 3/4 represent on the map? Pls help im not caught up on the algebra thing Btw 1 inch is equivalent to 12 miles on the map
Answer:
45 miles
Step-by-step explanation:
Complete Question
What does 3 3/4 inches represent on the map?
1 inch is equivalent to 12 miles on the map
From the above question, the scale on the map is given as:
1 inch = 12 miles
Hence, 3 3/4 inches = x miles
Cross Multiply
1 inch × x miles = 3 3/4 inches × 12 miles
x miles = 3 3/4 inches × 12 miles/1 inch
x miles = 15/4 × 12 miles
x miles = 45 miles
Therefore, 3 3/4 inches represents 45 miles on the map.

in a maths class,the girl to boy ratio is 7:5 if there are 20 boys,how many girls are there?
Answer:
28:20
Step-by-step explanation:
you just multiply 5 by 4 because 20 divided by 4 is 5 and then multiply 7 by 4
Answer:
Let total students be ‘X’
No of girls = (X-20)
Girls/Boys=7/5=(X-20)/20
7(20) =5(X-20)
140=5X-100
5X=240
X = 240/5
X =48
So, Total Students are 48
No of girls = (X-20) = 48-20 = 28
