s is inversely proportional to t
When s = 0.5, t = 7
Work out s when t = 0.8
Answers
Given:
s is inversely proportional to t.
When s = 0.5, t = 7.
To find:
The value of s when t=0.8.
Solution:
s is inversely proportional to t.
[tex]s\propto \dfrac{1}{t}[/tex]
[tex]s=\dfrac{k}{t}[/tex] ...(i)
Where, k is the constant of proportionality.
Putting s=0.5 and t=7, we get
[tex]0.5=\dfrac{k}{7}[/tex]
[tex]0.5\times 7=k[/tex]
[tex]3.5=k[/tex]
Putting k=3.5 in (i), we get
[tex]s=\dfrac{3.5}{t}[/tex]
This is the equation of proportionality.
Putting t=0.8, we get
[tex]s=\dfrac{3.5}{0.8}[/tex]
[tex]s=4.375 [/tex]
Therefore, the value of s is 4.375 when t=0.8.

Jonny and Faheem share some money in the ratio 3:5. Faheem gets £12 more than Jonny. How much does Jonny get?
Answers
Given:
Jonny and Faheem share some money in the ratio 3:5.
Faheem gets £12 more than Jonny.
To find:
The amount that Jonny gets.
Solution:
Jonny and Faheem share some money in the ratio 3:5.
Let Jonny and Faheem get 3x and 5x.
Different between their amounts is
[tex]5x-3x=2x[/tex]
Faheem gets £12 more than Jonny. It means the difference between their amounts is equal to £12.
[tex]2x=12[/tex]
[tex]x=\dfrac{12}{2}[/tex]
[tex]x=6[/tex]
The amount that Jonny gets is
[tex]3x=3(6)[/tex]
[tex]3x=18[/tex]
Therefore, Jonny gets £18.

A triangle has a base of 18.1 kilometres and a height of 17.4 kilometres. What is the area?
Answers
Answer:
157.47km²
Step-by-step explanation:
Given the following
base of 18.1 kilometres
height of 17.4 kilometres
Area of the triangle = 1/2 * base * height
Area of the triangle = 1/2 * 18.1 * 17.4
Area of the triangle = 314.94/2
Area of the triangle = 157.47km²
Hence the area of the triangle is 157.47km²

4p+5q = 57

Subtract the second equation from the first equation.
4p+5q = 57
-9p-5q = -72
——————
-5p = -15
p = 3
4(3)+5q = 57

The pair of shorts costs £18.90
Helen only has £70 to spend,
Does Helen have enough money to buy the 2 shirts and the pair of shorts?
Answers

yes
Step-by-step explanation:
2*24.50=49 (two shirts)
18.90 (pair of shorts)
49+18.90=67.90
she can spend 70, means she can buy all of those and she still has 2.10
Rita is designing a building shaped like a pyramid that's cut off in a plane parallel to its base (this is called a truncated pyramid). The building has a 64×64 m end text square base and is 36 m tall. The cut off section has an a16×16m square base and is 12 m tall. What is the volume of the building? Round to the nearest cubic meter.
Answers
Answer:
64,512 m3
Step-by-step explanation:
3 1
(base area)(height) = 3 1
(64⋅64)(48) =65,536
The volume of the building is 64512 cubic meters if the pyramid that's cut off in a plane parallel to its base.
What is a right square pyramid?In geometry, it is defined as the shape having a square base with equal sides length and all the vertex of the squares joints at the top which is perpendicular to the center of the square.
We know volume for the right square pyramid is given by:
[tex]\rm V= \frac{1}{3} b\times h[/tex]
Volume for the cut off portion:
[tex]\rm v = \dfrac{1}{3}\times16\times16\times12[/tex]
v = 1024 cubic meters
Volume for the completer pyramid"
[tex]\rm V=\dfrac{1}{3}\times64\times64\times48[/tex]
V = 65536 cubic meters
Volume of the building = 65536 - 1024
= 64512 cubic meters
Thus, the volume of the building is 64512 cubic meters if the pyramid that's cut off in a plane parallel to its base.

That’s because in radicals if there’s a square inside they square root that and put it on the outside. For example for √8, it would be 2√2, since the four can be square rooted, and there is still a 2 left inside the square root. For √48, there is a sixteen inside so you square root the 16 and get 4√3.

Three students have already enrolled for a creative writing class. The teacher will cancel the class if there are fewer than 10 students enrolled. Write three values for numbers of students needed to sign up so that the the creative writing class can be held
Answers
Answer:
7, 10 and 15
Step-by-step explanation:
Given
[tex]S_1= 3[/tex] --- Students already enrolled
[tex]Total = 10\ (less)[/tex]
Required
Determine the additional number of students needed for the teacher not to cancel the class
First, we need to calculate the number of students for the teacher to cancel the class.
Represent this with x.
So, we have:
[tex]S_1 + x < Total[/tex]
Make x the subject
[tex]x < Total - S_1[/tex]
Substitute values for Total and S1
[tex]x < 10 - 3[/tex]
[tex]x < 7[/tex]
This means that if less than 7 additional students come to the class, the teacher will cancel the class.
So, for the teacher not to cancel the class, the students must be 7 or greater (i.e. 7, 8, 9, 10....)
