A veichle uses 150 litres of petrol in 45 minutes. How many litres of petrol will it use in 1 hour 15 minutes?
The amount of petrol consumed in one hour will be 200 liters.
A ratio is a group of sequentially ordered numbers a and b expressed as a/b, where b is never equal to zero. When two objects are equal, a statement is said to be proportional.
In 45 minutes, an automobile uses 150 gallons of gasoline.
Consequently, the rate of gasoline consumption in liters per minute will be
= 150 / 45
= 10 / 3 Liters per minute
We are aware that an hour is made up of 60 minutes.
The amount of gasoline that will be used in an hour will then be
= (10 / 3) x 60
= 10 x 20
= 200 liters
Thus, 200 liters of gasoline will be burned in an hour.

use multiplication to show how how many twenty fourths equal 3/6
Answer:
10 times
Step-by-step explanation:
To figure this out, the first thing we will do is to find the LCM (Least Common Multiple). We will do this by making a list of the denominators that we have right now. Right now we have [tex]\frac{20}{4}[/tex] and [tex]\frac{3}{6}[/tex]. We will use 4 and 6 to make a list to find our multiple that is in both lists. (That comes up first)
Multiples of 4: 4, 8, 12, 16, 20, 24, 28, 32...
Multiples of 6: 6, 12, 18, 24, 30, 36, 42...
Now, we just realized that we have 24 that are in common with both 4 and 6. Now we will multiply both the numerator and denominator by the same number to have the denominator equal 24.
[tex]\frac{20}{4} * \frac{6}{6}[/tex] = [tex]\frac{120}{24}[/tex] & [tex]\frac{3}{6} * \frac{4}{4}[/tex] = [tex]\frac{12}{24}[/tex]
Now that we have [tex]\frac{120}{24}[/tex] and [tex]\frac{12}{24}[/tex]. We will read the question again about how many [tex]\frac{3}{6}[/tex] equal to [tex]\frac{20}{4}[/tex]. Since we have our fractions, we will add [tex]\frac{12}{24}[/tex] multiple times until we get [tex]\frac{120}{24}[/tex].
[tex]\frac{12}{24} + \frac{12}{24} + \frac{12}{24} + \frac{12}{24} + \frac{12}{24} + \frac{12}{24} + \frac{12}{24} + \frac{12}{24} + \frac{12}{24} + \frac{12}{24} = \frac{120}{24}[/tex]
Therefore, [tex]\frac{3}{6}[/tex] equals to [tex]\frac{20}{4}[/tex] 10 times.
In a certain country 23% of the population has a college degree and 7% of those people have an advanced degree (masters of above). If the country has 3,000,000 people than how many people have advanced degree?
Answer: 48300
Step-by-step explanation:
23 % of 3.000.000 is [tex]\frac{3.000.000*23}{100} = 690.000[/tex]
So, 690.000 have college degree.
7 % of 690.000 is [tex]\frac{690.000* 7}{100} = 48.300[/tex]
So, 48.300 people have advanced degree.

How to show that the two shaded regions are equalgiven data
ACD is a sector of a circle
From the figure we deduce that arc AC with line O is a quadrant of a circle. Hence the area of the shaded part of the quadrant is:
= area of a circle /4 - area of the right angle triangle
where area of a circle = pi r^2
area of triangle = 1/2 * base * height = bh/2
Area of the shaded part of the quadrant
= ( pi * r^2) / 4 - bh/2
base AO = radius of the circle = height CO
this forms an isosceles triangle and base angles of an isosceles triangle are equal. < A = < C = x
< A + < C + 90 = 180
x = 45 degrees
area of sector
= ∅/360 * pi*r^2
= (45 / 360) * (pi*r^2)

After a tax of 22%, a car sells for $9800.
What was its original price?
Before a tax of 22 %, the product has an original price of $ 8032.79.
How to determine the original price of a product
In this problem we find the case of a product that is sold including a given tax, that is, the price of the product before taxes. The original price can be found by means of the following equation, which is in terms of resulting price and tax rate:
C = C' / (1 + r / 100)
Where:
C - Original price, in monetary unit.C' - Resulting price, in monetary unit.r - Tax rate, in percentage.If we know that C' = $ 9800, r = 22 %, then the original price of the product is:
C = 9800 / (1 + 22 / 100)
C = 9800 / (122 / 100)
C = 9800 / 1.22
C = $ 8032.79

The diagram shows a prism. The cross section of the prisim is a right-angled triangle. The base of the triangle has length 5cm. The prisim has length 25cm. The prisim has volume 750. Work out the height of the prisim.
The height of the triangular prism is calculated as: 12 cm.
How to Find the Height of a Right-Triangular Prism?The volume of a right-triangular prism = 1/2(base of triangular face)(height of triangular face)(length of the triangular prism).
Given the following:
Base length of the triangular face = 5 cmVolume of the right-triangular prism = 750 cubic cmLength of the right-triangular prism = 25 cmHeight of the right-triangular prism (height of the triangular face) = hPlug in all the values into the volume formula for the triangular prism:
750 = 1/2(5)(h)(25)
750 = (1 × 5 × h × 25)/2
750 = (125h)/2
Multiply both sides by 2
750 × 2 = (125h)/2 × 2 [multiplication property of equality]
1,500 = 125h
Divide both sides by 125
1,500/125 = 125h/125 [division property of equality]
12 = h
h = 12 cm
Thus, the height of the prism that has a base of the triangle measuring 5cm, a prism length of 25 cm., and a volume of 750 cubic cm is determined as 12 cm.
