Coprime numbers:
A Co-prime number is a set of numbers or integers which have only 1 as their common factor.
For eg: (2,3), (11,12), (99,100) and so on; they have 1 as their HCF. The sum of any two coprime numbers is always coprime with the product of the same two coprime numbers. For eg: The sum of 2 and 3 is 5 and the product of 2 and 3 is 6. Hence, 5 and 6 are coprime numbers.
Prime number
A number that can be divided exactly only by itself and 1, for example 7, 17 and 41
-5/8c = 20....multiply both sides by -8/5 (this cancels out the -5/8 on the left
c = 20(-8/5)
c = -160/5
c = - 32
check..
-5/8(-32) = 20
160/8 = 20
20 = 20 (correct)
so c = -32
Answer:
The answer is 30
Step-by-step explanation:
First you have to find 120% of a (12).
Therefore; 14.4 is 80% of b, and we are trying to find 100% of b
we do not know what is 100% therefore we call it *x*. In order to find this unknown value *x* we cross multiply.
This is the same as saying;
100% percent would be 1 because it is the whole number we are trying to find. The 80% would be 4/5. To get 4/5 you can simply break down 80/100 ( this is 80% as a fraction).
so the new equation is: 14.4= 4/5x
We divide both sides by 4/5. Then we will get x tobe equal to 18. Therefore b is 18. We were asked to find (a + b) so.<em> </em><em>1</em><em>8</em><em>+</em><em>1</em><em>2</em><em> </em><em>=</em><em> </em><em>30</em>
Answer:
$400 dollars in five dollar tickets then $399 dollars in seven dollar tickets.
so you do $400+$399=799
Step-by-step explanation:
You do $400÷5=80 then you do $395R4÷7=55 Then you do 55+80=$135.
so 55 adult tickets and then 80 student tickets.
The surface area of square pyramid is the sum of the area of all its sides.
If l is the slant height and base is s each then surface area of pyramid is given by:
Surface area = s2+2xsx l
From the given figure in the question:
S=6 cm ,l= 8cm.
Substituting these values in surface area formula we have:
Surface area = 62+2x6x8
Surface area = 36+96
Surface area =132cm2
