A man buys a washing machine whose price VAT (value added Tax ) is Birr 175. lts VAT is charged at 15 % ,how much did the man actually pay?
9514 1404 393
Answer:
Birr 1341.67
Step-by-step explanation:
The tax is 15% of the price (p), so we have ...
0.15p = 175
p = 175/0.15 = 1166.67
When the tax is added, the total comes to ...
1166.67 +175 = 1341.67
The man actually paid Birr 1341.67.
if you start at 89 degrees and it decreases 5% each hour what would it be at in 3 hours
Answer:
A = 76.3 degrees after 3 hours
Step-by-step explanation:
An exponential function is needed here:
A = P(1 - 0.05)^3, where this (1 - 0.95) reflects a DECREASE of 5%/hour.
Then: A = (89 degrees)(0.95)^3, or
A = 76.3 degrees after 3 hours
HELP PLEASE! What is the slope of the line shown?
Answer:
A. -4/11
Step-by-step explanation:
Slope formula: [tex]\frac{y^2 - y^1}{x^2 - x^1 }[/tex]
Using the two points substitute the coordinates into this formula
6-2 = 4
4 - 7 = -11
Put 4 over -11 because it is the y value
[tex]-\frac{4}{11}[/tex]
The price of 1 kg of silver on 1st January 2010 was $607
By 1st January 2015, the price of 1 kg of silver had decreased by 9.4%
Work out the price of 1 kg of silver on 1st January 2015.
Give your answer correct to the nearest dollar
Answer:
550
Step-by-step explanation:
9.4/100 multiplied by 607 is 57
subtract this from 607 and the answer is 549.9, to the nearest dollar is 550
a number is two more than another number in number form?
From the information in the word problem we are able to set up the following inequality:
3y + 2 - y = 12 | where x is the larger number of two numbers in a set (x, y)
We know this because the problem states that [x = 3y + 2] or 3 times the smaller number plus two.
We also know that x - y = 12.
So, we substitute x in [x - y = 12] with 3y + 2 that we found out above, and we get the following:
3y + 2 - y = 12
Now, we solve the inequality
3y + 2 - y = 12
-> subtract 2 from both sides :: 3y - y = 10
-> subtract y from 3y :: 2y = 10
-> divide both sides by 2 :: y = 5
So now we have y, the smaller number, which is equal to 5. Next, to find x we simply plug y=5 back in to either the value of x, [3y + 2], or the inequality of x - y = 12. I will show both:
x - y = 12
-> substitute y for 5 :: x - 5 = 12
-> add 5 to both sides :: x = 17
OR
3y + 2 = x
-> substitute y with 5 :: 3(5) + 2 = x
-> multiply 3, 5 :: 15 + 2 = x
-> add 15, 2 :: 17 = x
So there you have it:
x = 17 , y = 5
You can go back and use these values to check your answer and make sure they work with the word problem.
Remember to look for the setup to an inequality in the word problem. Anything that says BLANK times this number, or 4 less than that number, is trying to set you up with an inequality problem.

The slope of any vertical line is?
Answer:
The slope of any vertical line is undefined.
Step-by-step explanation:
The slope of a line is the change in Y divided by the change in X. The slope of a horizontal line = 0 (not undefined). The slope of a vertical line is undefined, however. Hope this helps; have a great day!

A farmer is going to plant more than 50 acres in corn this year.
If a represents the number of acres planted in corn, write an inequality to describe all possible values of a.
a>50A is greater than 50
a<50a<50
a≥50A is greater than or equal to 50
a≤50
Answer:
+ 1) is an even number.
Take any n ∈ N, then n is either even or odd.
• Suppose n is even ⇒ n = 2m for some m ⇒ n(n + 1) = 2m(n + 1) ⇒ n(n + 1) is even.
• Suppose n is odd ⇒ n+ 1 is even ⇒ n+ 1 = 2m for some m ⇒ n(n+ 1) = 2nm ⇒ n(n+ 1)
is even. QED

Which of the following would not be a line in solving the equation:
7x-8-5x = 52
12x = 60
12x = 44
12x - 8 = 52
x = 5
Answer:
Step-by-step explanation:
Let's actually solve the equation. By doing so we should readily see which of the given equatins are not part of the solution.
7x - 8 - 5x = 52 becomes 2x - 8 = 52 if we consolidate the x terms. Next, we consolidate the constant terms on the right, obtaining 2x = 60.
Then x = 30 is the solution.
12x = 60 would not be part of the solution.
12x = 44 would not either.
12x - 8 = 52 would not either.
x = 5 would not be part of the solution.
Again: The solution is x = 30.

Parallelogram L M N O is shown. Angle N is (5 x) degrees and angle L is (3 x + 40) degrees. In parallelogram LMNO, what is the measure of angle M? 20° 60° 80° 100°
Answer:
80degrees
Step-by-step explanation:
Find the diagram attached
From the diagram, the opposite angle of the parallelogram are equal hence;
5x= 3x+40
5x - 3x = 40
2x = 40
x = 40/2
x = 20degrees
Also <M + <N = 180
<M + 5x = 180
<M + 5(20) = 180
<M + 100 = 180
<M = 180-100
<M = 80degrees
Hence the measure of angle M is 80degrees
Answer:
80

A shop has a fridge in a sale.The shop gives an extra 10% off the sale price of the fridge. Oliver says,"Altogether this is a saving of 30%"Is he correct?
Answer:
He is incorrect
Step-by-step explanation:
Given
[tex]Price\ off = 10\%[/tex]
Required
Is the total savings, 30%
From the question, we understand that the price of is 10%.
Since there is no other deduction to the original price of the fridge, then the 10% represents the total savings.
Hence: 30% savings is incorrect.
