There are two numbers such that , if both of them are individually increased by 5 and then by the same percentage as they were i

QveST [7]

Let the two numbers be x and y.
Let m = the fraction (or percentage) for increasing the numbers.

Increase x by 5, multiply (x+5) by (1+m), and set it qual to 36.
(x + 5)*(1 + m) = 36

Increase y by 5, multiply (y+5) by (1+m), and set it equal to 36.
(y+5)*(1+m) = 36

Therefore
(x+5)*(1+m) = (y+5)*(1+m)
x + 5 = y + 5
x = y
x - y = 0

Answer: 0.
The difference between the two numbers is zero.

No matter what the indices are just follow the law of indices for division:

xᵃ ÷ xᵇ = xᵃ - ᵇ. Most importantly the base x must be the same.

Find the height of the triangle 10 points!

Scorpion4ik [409]

By the 6 trigonometric ratios in a right triangle

(sine, cosine, tangent, cotangent, secant, cosecant)

we have the following:

$\displaystyle{ sin20^o= \frac{opposite \ side}{hypothenuse}= \frac{x}{10}$

So, $x=10\cdot sin20^o$

sin20° must be given, or can be found using a calculator:

Using the calculator of our pc: Calculator- view:Scientific- press 20 then sin button, we find : sin20°=0.342

$x=10\cdot sin20^o=10\cdot0.342=3.42$

Answer: A)3.4

Use the net below to determine the surface area of the cylinder. (Use 3.14 for Tr.)

baherus [9]

Option D:

Surface area of the cylinder = 753.6 cm²

Solution:

To find the surface area of the cylinder:

Given data:

Radius of the cylinder = 6 cm

Height of the cylinder = 14 cm

The value of π = 3.14

Surface area of the cylinder = $2 \pi r^{2}+2 \pi r h$

$=2\times 3.14\times6^2+2\times3.14\times 6 \times14$

= 226.08 + 527.52

= 753.6 cm²

Surface area of the cylinder = 753.6 cm²

Option D is the correct answer.
