The quotient when 0.03 is divided by 0.148 after rounding it off is 0.2.
According to the question,
We have the following information:
0.03 is divided by 0.148
And it can be simply expressed as 0.03/0.148
Now, we have the quotient as:
0.2027
Now, when rounding off the numbers we know that the digits from where we are rounding off we look at the right next to that digit and when that digit is greater than 5 then the digit should be increased by 1 and when that digit is less than 5 then the digit should be the same.
So, we will round it off by taking the underlined digit to be next to first 2:
So, the digit is 0.
Butt if we are taking the underlined digit as 2 to be the next 2 then the digit next to it is 7 which is greater than 5.
Then, we have:
0.2
Hence, the quotient when 0.03 is divided by 0.148 after rounding it off is 0.2.

The shortest side of a right angle triangle is 6cm shorter than the hypotenuse. The difference in length of the other two sides is 3cm. If the shortest side is n - 3, show that 2n squared equals 12n. Hence, n.
The value of n in the right triangle is 12 cm.
How to find the side of a right triangle?The shortest side of a right angle triangle is 6cm shorter than the hypotenuse.
The difference in length of the other two sides is 3cm.
The hypotenuse side is the longest side of a right triangle.
Hence,
hypotenuse side = n - 3 + 6
hypotenuse side = n + 3
Shortest side of the right triangle = n - 3
Other side = n
Therefore, using Pythagoras theorem,
(n + 3)² = (n - 3)² + n²
(n + 3)(n + 3) = (n - 3)(n - 3) + n²
n² + 3n + 3n + 9 = n² -3n -3n + 9 + n²
n² + 6n + 9 = 2n² - 6n + 9
Therefore,
2n² - n² + 9 - 9 = 6n + 6n
n² = 12n
n² - 12n = 0
n(n - 12) = 0
n = 0 and n = 12
Therefore,
n = 12

How to interpret slope on linear graph?The formula to find the slope from two coordinate points is;
m = (y2 - y1)/(x2 - x1)
To get the slope, let us use points A and B;
A(0, 0) and B(1, 0.9)
Thus;
Slope = (0.9 - 0)/(1 - 0)
Slope = 0.9
Let us use points C and D to verify the slope.
Slope = (2.6 - 1.7)/(3 - 2)
Slope = 0.9

The double number lines show the ratio of yards to miles.
How many yards are in 4 miles?
Answer:
Guess it's 7.040 yards in 4 miles
Step-by-step explanation:
8.800÷5= 1.760 in 1 yard
4×1.760=7.040
prove me wrong
Answer:
In both number lines, from 0-8,800 and 0-5 there are 5 notches from the first and last, so what you first want to do is solve for the first number line. You can do this by divideing the largest number by the number of notchest on the line:
8,800/5 = 1760
So the notch after 0 will be 1760. To finish the pattern, you want to add the number you got after dividing the total, by itself, 4 more times, as shown:
1,760 + 1,760 = 3,520
3,520 + 1,760 = 5,280
5,280 + 1,760 = 7,040
7,040 + 1,760 = 8,800
Now the number line will look like this:
0, 1760, 3520, 5280, 7040, 8800
0, 1, 2, 3, 4, 5
Compared to the second number line we find that there are 7,040 yards in 4 miles!

Lucy used 3 3/4 cups of sugar for her lemonade stand. She divided the
sugar, in equal amounts, into 6 pitchers. How much sugar went into each
pitcher?
The amount of sugar that went into each pitcher was 0.375, which was taken from the 3(3/4) cups of sugar utilized for the lemonade stand.
What is the point of dividing?Division allows us to divide a large number of objects into equal-sized groups. Division is represented by the symbol ÷.
Which property is employed in division?We can use the distributive property to divide larger numbers by breaking them down into smaller factors.
It is implied that Lucy made her lemonade stand using 3 3/4 cups of sugar.
Further, she distributed the sugar into 6 pitchers in equal portions.
Therefore, we need to divide the total cups of sugar by 6 to get the value of sugar that went into each pitcher.
sugar went into each pitcher = 3(3/4) ÷ 6
= (9/4) ÷ 6
= 2.25 ÷ 6
= 0.375
Therefore, each pitcher of sugar contained 0.375 of the 3(3/4) cups of sugar utilized for the lemonade stand.

The solution of the system of equation is [tex]e=1 , d= 3[/tex] [tex],f=3[/tex]
How do you solve algebra?The area of mathematics known as algebra is used to help express issues or circumstances into mathematical expressions. We employ integers with definite or fixed values in algebra, such as 2, 7, 0.068, etc. In addition to integers, algebra uses variables like x, y, and z.
The solution is written as below:
Given: d= f
2d + 4e - 3f = 1 --------------1
and - 3d + 2e + 4f = 5----------------------2
Put the value of f as d because it is given,
thus equation becomes; 2d+ 4e - 3d= 1 ⇒ 4e- d= 1 ----3
-3d+2e +4d= 5 ⇒ 2e+ d=5 ----4
Thus on solving 3 and 4 we get;
[tex]4e-d=1\\+2e+d=5\\[/tex]
We get 6e= 6 which implies e= 1
And putting this value of e in equation 3 we get,

Towns A and B are 240 km apart.
A bus takes 80 minutes longer than a car to travel between the two towns.
The car is travelling at 15 km/h faster than the bus which is travelling at × km/h.
(a) Find the time, in hours,

(b) Form an equation in × and
show that it reduces to ×2 + 15x - 2700 = 0
(c) Solve the equation and find the speed of the bus and
the time taken by the car to travel between the two towns.
The time (in hours) taken by the bus and the car to travel between the two towns in terms of x is 5 hours 20 minutes and 4 hours respectively and the equation in x formed is [tex]x^2 + 15x -2700=0[/tex]
Given that:-
Distance between towns A and B = 240 km
A bus takes 80 minutes longer than a car to travel between the two towns.
The car is travelling at 15 km/h faster than the bus which is travelling at x km/h.
Let the speed of the bus be s km/hr and,
The time taken by the car to travel from A to B be t hours.
Hence,
(15+x)*t = (t + 80/60)*x
15t + xt = xt + 4x/3
15t = 4x/3
t = 4x/45 hours.
Hence,
(15 + x)*(4x/45) = 240
x(x + 15)/45 = 60
[tex](x^2 + 15x) = 60*45[/tex]
[tex](x^2 + 15x) = 2700\\x^2 + 15x -2700=0\\x^2-45x+60x-2700 = 0[/tex]
x(x-45) +60(x - 45) = 0
(x - 45)(x + 60) = 0
x = 45,-60
As the time cannot be negative,
x = 45 km/hr
t = (4*45)/45
t = 4 hours (time taken by car)
Time taken by bus = 4 hours + 80 minutes = 5 hours 20 minutes
