Y~1/x² (Pardon the proportionality sign)

Y=k/x²

K=yx²

Substitute the values

K=4×3²

k=36

Y=k/x²

K=yx²

Substitute the values

K=4×3²

k=36

The total number of students is 100

And 30 students are 15 years old

To turn it to angle,

30/100×360

That's 108°

And 30 students are 15 years old

To turn it to angle,

30/100×360

That's 108°

Drawing the triangle, you have the angle of 60° the adjacent 30 and opposite x

We are looking for x so we use the function that has these three values that's tan

Tan 60= opposite/adjacent

Tan 60= x/30

X= tan 60 x 30

That's 51.96m

Factorize completely the expression abx\(^2\) + 6y – 3ax – 2byx. | Mathematics Past Questions

Collect terms that look closest to each other

(abx²-2byx)(6y-3ax)

What's common?

bx(ax-2y)-3(-2y-ax)

Note: always make sure the terms in both brackets are same to know if you're getting it

Collect the ones outside the brackets

(ax-2y)(bx-3)

(abx²-2byx)(6y-3ax)

What's common?

bx(ax-2y)-3(-2y-ax)

Note: always make sure the terms in both brackets are same to know if you're getting it

Collect the ones outside the brackets

(ax-2y)(bx-3)

Express the product of 0.0014 and 0.011 in standard form. | Mathematics Past Questions

Turn them to standard form first

14×10^-⁴ and 11×10^-³

Multiply 14 by 11 that's 154

Multiply the standard forms too

So, 10^-⁴ × 10^-³=10^-³-⁴= 10^-7

The answer is 154×10^-7 then turn it to the form of the options that's 1.54×10^-5

14×10^-⁴ and 11×10^-³

Multiply 14 by 11 that's 154

Multiply the standard forms too

So, 10^-⁴ × 10^-³=10^-³-⁴= 10^-7

The answer is 154×10^-7 then turn it to the form of the options that's 1.54×10^-5

A pyramid is constructed on a cuboid. The figure has | Mathematics Past Questions

Just count the number of lines to draw the image...you get 16...that's 16 edges

It has 9 faces and 9 vertices

It has 9 faces and 9 vertices

Let's say the original price is 100₦

X sold it at a profit of 20% to y

20/100×100 that's 20₦ +100. =₦ 120

Y bought at 120...then y sold at a loss of 20%

So

20/100×120 is 24

120-24=96₦

Y sold it at 96 naira to z

So

96:100 24:25

X sold it at a profit of 20% to y

20/100×100 that's 20₦ +100. =₦ 120

Y bought at 120...then y sold at a loss of 20%

So

20/100×120 is 24

120-24=96₦

Y sold it at 96 naira to z

So

96:100 24:25
