market stall holder bought a variety of coloured 'hoodies to sell. Each hoodie costs the stall holder $20 and she intends to sell them to the public at a mark up of 65%
write the percentage mark up value as:
1) fraction in simplest form
2) decimal
Answer:
20 x 0.65 = 13
20 + 13 = 33
20 x 65/100 = 13

Tiles with the letters A, B, C, D, E, F, G, and H written on them are placed in a bag. Malik draws out one letter at random. Which statements about the situation are true? Check all that apply.
The number of possible outcomes is 8.
The probability of drawing the tile with E written on it is 1/4
P(vowel) = 1/4
P(vowel) + P(consonant) does not = 1
Choosing one letter at random is a simple event.
Answer:
P(vowel) = [tex]\frac{1}{4}[/tex]
Choosing one letter at random is a simple event.
Step-by-step explanation:
P(vowel) = [tex]\frac{1}{4}[/tex]
This is because there are 2 vowels so the probability [tex]\frac{2}{8}[/tex] is which can be simplified to [tex]\frac{1}{4}[/tex] .
Moreover, Choosing one letter at random is a simple event.
The definition of a simple event is one that can only happen in one way, or in other words, it has a single outcome.
Malik's probability of drawing one letter at random is 1/4.
Probability calculation:P (vowel) = [tex]\bold{ \frac{1}{4}}[/tex] It's good to select one letter at random. P(vowel) = [tex]\bold{ \frac{1}{4}}[/tex]Since there are two vowels, the probability is [tex]\bold{ \frac{2}{8}}[/tex], is equal [tex]\bold{ \frac{1}{4}}[/tex].Furthermore, picking one letter at random is an easy procedure.A simple event is one that can only happen one way or has just one conclusion.Find out more about the probability here:

Charles and Seth are building a ramp for Sasha and Samantha. The base of the triangle is 11ft and it's height is 5ft. How long is the diagonal of the ramp?
Answer: 12.1 ft
Step-by-step explanation:
A ramp represents a right-angled triangle so Pythagorean formula can be used to find the diagonal length which will also be the hypotenuse.
c² = a² + b²
Where:
c = hypotenuse
a = base
b = Height
c² = 11² + 5²
c² = 121 + 25
c² = 146
c = √146
c = 12.1 ft
Please help! (20 points)
Find the values of A and B in each triangle: show your work
Answer:
soh cah toa
to find a use sin =opp/hyp
sin 32=opp or a /hyp
sin 32*hyp=9.53
then to find b you can pythagorean theorem or just use cah or cos =adj/hyp
same process as above only using cos instead of sin
you get 15.3
then a^2+b^2=c^2
9.53^2+15.3^2=18^2 just to check or to use to find either a or b given c and either a or b

-2(v - 2) = -3 – 2v
Answer:
no solution
Step-by-step explanation:
Given
- 2(v - 2) = - 3 - 2v ← distribute left side
- 2v + 4 = - 3 - 2v ( subtract 4 from both sides )
- 2v = - 7 - 2v ( add 2v to both sides )
0 = - 7 ← not possible
This indicates the equation has no solution

What is the y-intercept of y=5x-2
Answer:
the y intercept is -2
Step-by-step explanation:
the y intercept is always the value on the end
Answer slope-intercept form is y = mx+ b y = m x + b, where m m is the slope and b b is the y-intercept. y = mx +b y = m x + b Find the values of m m and b b using the form y = mx+b y = m x + b.

What are the solutions to (3x - 2) (4x + 1) = 0?
9514 1404 393
Answer:
x = 2/3, -1/4
Step-by-step explanation:
The zero product rule tells you a product will be zero only if one or more factors is zero. The solutions to this equation are the values of x that make one or the other of the factors be zero.
3x -2 = 0
3x = 2
x = 2/3 . . . . makes the first factor zero
__
4x +1 = 0
4x = -1
x = -1/4 . . . . makes the second factor zero
__
The solutions are ...
x = 2/3 or x = -1/4

Prove that √sec²
Given:
Consider the given statement is
[tex]\sqrt{\sec^2\theta+\text{cosec}^2\theta}=\tan \theta+\cot \theta[/tex]
To prove:
The given statement.
Solution:
We have,
[tex]\sqrt{\sec^2\theta+\text{cosec}^2\theta}=\tan \theta+\cot \theta[/tex]
Taking LHS, we get
[tex]LHS=\sqrt{\sec^2\theta+\text{cosec}^2\theta}[/tex]
[tex]LHS=\sqrt{\dfrac{1}{\cos^2\theta}+\dfrac{1}{\sin^2\theta}}[/tex]
[tex]LHS=\sqrt{\dfrac{\sin^2\theta+\cos^2\theta}{\sin^2\theta\cos^2\theta}}[/tex]
[tex]LHS=\sqrt{\dfrac{1}{\sin^2\theta\cos^2\theta}}[/tex] [tex][\because \sin^2\theta+\cos^2\theta=1][/tex]
[tex]LHS=\dfrac{1}{\sin\theta\cos\theta}[/tex]
[tex]LHS=\dfrac{\sin^2\theta+\cos^2\theta}{\sin\theta\cos\theta}[/tex] [tex][\because \sin^2\theta+\cos^2\theta=1][/tex]
[tex]LHS=\dfrac{\sin^2\theta}{\sin\theta\cos\theta}+\dfrac{\cos^2\theta}{\sin\theta\cos\theta}[/tex]
[tex]LHS=\dfrac{\sin\theta}{\cos\theta}+\dfrac{\cos\theta}{\sin\theta}[/tex]
[tex]LHS=\tan \theta+\cot \theta[/tex]
[tex]LHS=RHS[/tex]
Hence proved.

Find the value of x. If needed round to the nearest tenth (one decimal place)
Answer:
x = 8.7
Step-by-step explanation:
The triangles are congruent, which means that the sides are proportional to each other. Line DE and line BE are proportional to each other. This means that:
8 = 12
We can simplify this down to
2 = 3
Now that we have this proportion we can apply it to Lines AE and EC
2(13) = 3x
26 = 3x
8.67 = x
Therefore x is equal to 8.67 (or 8.7 rounded)
Check:
8/12 = 0.6667
8.6667/13 = 0.6667
Since both are the same, the answer is correct.
I hope this helps!!
