Work out the area of a triangle of bass 12 cm and height 7 cm
Answers
The best thing to do is to multiply the answers then half them.
7*12= 84
84/2= 42
Therefore, the area is 42cm2
Hope this helps :)

Help The sum of two numbers is 200 and the two numbers are in a ratio of 4:6.Find the larger number.
A number x is decreased by 45. The result is then divided by 12. Then 20 is added to this new result to give a final result of five times the difference of 32 and the number x
Answers
(This is a little difficult but I've got it)
((x - 45)/12) + 20 = 5(32 - x)
(I made the equation a little more complex than I should have but that equation should still work if you were to solve for x)
Hey there!!
Let's get this step by step
x is decreased by 45 = x - 45
Result is divided by 12 = ( x - 45 ) / 12
Then, 20 is added to the result
[ ( x - 45 ) / 12 ] + 20
Result =
Five times the difference of 32 and x = 5 ( 32 - x )
Hence, the equation
[ ( x - 45 ) / 12 ] + 20 = 5 ( 32 - x )
( x - 195 ) / 12 = 160 - 5x
Multiply 12 on both sides
x - 195 = 12 ( 160 - 5x )
x - 195 = 1920 - 60x
Add 60x on both sides and add 195 on both sides
61x = 2115
divide by 61 on both sides
x = 34.67
x = 34.7
Hence, the required answer is 34.7 this can be rounded to 35
Hope my answer helps!

Answer:Concept Development: We have learned why scientific notation is indispensable in science. This means that we have to
learn how to compute and compare numbers in scientific notation. We have already done some computations, so we
are ready to take a closer look at comparing the size of different numbers.
Step-by-step explanation:There is a general principle that underlies the comparison of two numbers in scientific notation: Reduce everything
to whole numbers if possible. To this end, we recall two basic facts.
1. Inequality (A): Let and be numbers and let > . Then < if and only if < .
2. Comparison of whole numbers:
a. If two whole numbers have different numbers of digits, then the one with more digits is greater.
b. Suppose two whole numbers and have the same number of digits and, moreover, they agree digitby-digit (starting from the left) until the
th place. If the digit of in the ( + )
th place is greater than
the corresponding digit in , then > .

Answer:
Since 0 in ln(3x) - 0 is not a logarithm, the property of logarithms cannot be used here.
The difference shown cannot be written as a quotient of logarithms.
The step ln(x2) = ln(3x) - (0) reduces to
ln(x2) = ln(3x).
The possible solutions are 0 and 3, with 0 being extraneous.

4-7x=18
Now you move the 4 onto the other side of the equal bars.
4-4-7x=18-4
Do the total.
-7x=14
Now you divide 14 by -7.
x=-2
There you have it.
