Milan bought 3 CDs that were each the same price. Including sales tax, he paid a total of $44.40. Each CD had a tax of $1.30. What was the price of each CD before tax?
Answer:
$13.5
Step-by-step explanation:
Given data
We are given that the tax per CD is $1.30
Hence for the 3 CDs the total tax = 3*1.3= $3.9
Also, the cost of the three CDs before tax = 44.4-3.9
=$40.5
Hence the cost of each CD before tax is
=40.5/3
=$13.5

Kiran is playing a video game. He earns 3 stars for each easy level he completes and 5 stars for each difficult level he completes. He completes more than 20 levels total and earns 80 or more stars
Answer:
10 easy levels and 10 difficult levels
Step-by-step explanation:
Given data
let the number of easy levels be x
and the number of difficult levels be y
so
x+y= 20----------1
and
3x+5y= 80------2
from 1
x=20-y
put this in 2
3(20-y)+5y= 80
60-3y+5y=80
2y=80-60
2y=20
y= 20/2
y= 10
put y= 10 in 1
x+10=20
x=20-10
x= 10
Hence Kiran played 10 easy levels and 10 difficult levels

Answer:
91.7 inches to 1 decimal place
Step-by-step explanation:
We will use Pythagoras's theorem to find the height of the pyramid.
The height of the Pyramid forms a right-angled triangle with half of the base and the slant height.
We can get half the length of the base by dividing the length of one side of the base = 20.4 by 2 = 10.2in
slant height = 92.3in
Therefore height = [tex]\sqrt{92.3^{2} -10.2^2} =91.73in[/tex]
The height of the pyramid is 91.73inches to 1 decimal place
find the value of X, please!
Answer:
x=42°
Step-by-step explanation:
We know that 2 of the legs are congruent, so the angles opposite them will be congruent.
The angles of a triangle add up to 180°
This can be represented by [tex]96+2x=180[/tex]
[tex]2x=84[/tex]
[tex]x=42[/tex]
Hope this helps :-)
Answer: 42 degrees
Step-by-step explanation: Since this is an isosceles triangle, your remaining two angles will be equal
There are 180 degrees in any triangle
Since you have already used 96 degrees, you must subtract to find what is remaining
180-96=84
Since your remaining two angles are equal, you can half 84 to find your answer
84/2=42
Both x and your one remaining angle should be 42
X=42

No they are not unequal... i. e. the two wires A and B are equal .
[tex]\frac{1}{3}[/tex] of A = [tex]\frac{1}{3}[/tex] of B

Are the graphs of y = -2x + 4 and y = (1/4)x -2 parallel, perpendicular, or neither? *
Answer: Neither
Step-by-step explanation:
For this to be paralell it would need to have the same slope. (They don't have the same.) For this to perpandicular it would have to reciporcal ( Ex: -2 reciporcal would -1/2 or 1/4 reciprocal would have to be 4)
Answer:
neither
Step-by-step explanation:
For two lines to be parallel, their slopes must be equal.
For two lines to be perpendicular, their slopes must have a product of -1. (The only exception is a vertical line and a horizontal line which are perpendicular, but the product of their slopes is not -1.)
When the equation of a line is written in the slope-intercept form,
y = mx + b,
m is the slope.
y = -2x + 4 has a slope of -2.
y = (1/4)x -2 has a slope of 1/4.
Clearly, -2 and 1/4 are not equal, so the lines are not parallel.
Now we find the product of the slopes.
(-2) * (1/4) = -2/4 = -1/2
The product of the slopes does not equal -1, so the lines are not perpendicular.
Answer: neither
When you flip a biased coin the probability of getting a tail is 0.2.
How many times would you expect to get tails if you flip the coin 240 times?
Answer:
48
Step-by-step explanation:
Multiply 0.2 × 240 = 48.
It's a very biased coin, so the outcome will be considerably less than the 120 we would expect from a fair coin.

Out of 15,000 voters in a constituency, 60% voted. Find the percentage of voters who did not vote. Can you now find how many actually did not vote?
Answer:
40 did not vote
6000 people did not vote
Step-by-step explanation:
1 % of 15,000 = 150
150 * 40 = 40% of 15,000 = 6000
Jessica makes $1500 a month at her job. If she saves 20% of it each month, how much savings will she have after one year? Remember that there are 12 months in one year!
$3,600
Step-by-step explanation:
You'd multiply 1,500 with .20 which equals 300. You'd then multiply 300 and 12 together to make $3,600.
What is the coefficient of m in the sum of (23m−34)( 3 2 m− 4 3 ) and (−16m−r)(− 6 1 m−r) ?
Answer:
77r - 2077
Step-by-step explanation:
To find the the sum of (23m−34)( 3 2 m− 4 3 ) and (−16m−r)(− 6 1 m−r)
First open the bracket
23m × 32m - 23m × 43 - 34 × 32m + 34 × 43
736m^2 - 989m - 1088m + 1462
736m^2 - 2077m + 1462
Open the second bracket
16m × 61m + 16m × r + r × 61m + r × r
976m^2 + 16mr + 61mr + r^2
976m^2 + 77mr + r^2
Adding both equations together
736m^2 - 2077m + 1462 + 976m^2 + 77mr + r^2
1712m^2 + 77mr - 2077m + 1462 + r^2
1712m^2 + m( 77r - 2077 ) + 1462 + r^2
Therefore The coefficient of m is 77r - 2077

Help me with my maths question and you get good luck 10 years
Answer:
Step-by-step explanation:
Let all the measurements be in same unit.
200 cm = 2 m
2000 mm = 2 m
Let distance jumped by Jack = x m
Distance jumped by Jerzy = x + 2
Distance jumped by Abdullah = (x+ 2) + 2 = x + 4
Total = 12.69 m
x + x +2 +x +4 = 12.69
x +x + x + 2 + 4 = 12.69
3x + 6 = 12.69
3x = 12.69 - 6
3x = 6.69
x = 6.69/3
x = 2.23 m
distance jumped by Jack =2.23m
Distance jumped by Jerzy = 2.23 + 2 = 4.23 m
Distance jumped by Abdullah = 2.23 + 4 = 6.23 m
