Answer:
Step-by-step explanation:
If a fractions denominator is a one that means the fraction is equal to the numerators whole number in this case we have 2/1 since the denominator is a 1 that means the whole fraction is equal to 2 because the numerator is 2.
Hope this helps.
Answer:
2.03403 * 10^2
Step-by-step explanation:
Here, we want to write the given number in standard form
Firstly, we need to write the number in the normal form;
Mathematically, that will be;
203.403
Now, to write in standard form, we move the zero to the back of the first non-zero digit which is 2
What we have in this case will be:
2.03403
How many times did we move the decimal point?
The decimal point was moved two times
So, what we have is that the number two will become a power of 10
So therefore, we have it that;
2.03403 * 10^2
Kindly note that if the movement was to the left, the power becomes a negative number on 10
Answer:
x = 12/5
Step-by-step explanation:
take the square of both sides
(x^2+49) = (x+5)^2
x^2 + 49 = (x+5) (x+5)
x^2+49= x^2 + 10x + 25
10x + 25 = 49
10x = 24
x = 12/5

Answer:
Length = 9units
Width = 7units
Step-by-step explanation:
It is said that the length is 2units more than the width
Assume that the width is x, then the length will be 2 + x
ie
Width = x
Length = 2 + x
Area of the rectangle = 63units
Area of rectangle = l * b
l - length of the rectangle
b - width of the rectangle
A = l * b
63 = (2 + x) * x
63 = ( 2 + x) x
63 = 2x + x^2
Let's rearrange it
x^2 + 2x - 63 = 0
Let's find the factor of 63
A factor that can be multiplied to give -63 and that can be added to give +2
Let's use -7 and +9
x^2 - 7x + 9x - 63 = 0
Separate with brackets
( x^2 - 7x) + ( 9x - 63) = 0
x( x - 7) + 9(x - 7) = 0
( x + 9)(x - 7) = 0
( x + 9) = 0
( x - 7) = 0
x + 9 = 0
x = -9
x - 7 = 0
x = 7
Note: the length of a rectangle can not be negative
So therefore,
x = 7
Length = 2 + x
= 2 + 7
= 9units
Width = x
= 7units
