(5.4×10^2)(2.5×10^8)
= (5.4 x 2.5) (10^2 × 10^8)
= 13.5 x 10^10
= 1.35 x 10^11
Answer:
Size 36.
Step-by-step explanation:
Find the fraction (with a denominator of 72) that equals 1/2. In this case, it's 36/72 because 72 divided by 2 is 36. 1/2 = 36/72, so the font size is 36.
PEMDAS
parenthesis, exponents, mult/division, add/subtract
parenthesis: 4+0.2= 4.2
exponents: 10^2= 10×10= 100
new equation: 10-5/100×0.4(4.2)
multiply/divide: 10-(1/20)×.4×4.2
10-(0.05)(0.4)(4.2)
10-0.002×4.2
add/subtract: 10-0.0084 = 9.9916
~this feels like a wrong answer~
Step-by-step explanation:
square of x is x2
Inverse of square of x is 1 / x2
So the equation would be:
y = k / x2
where k is a proportionality constant.
To find the value of k, plug in the known values for x and y: x=3, y=45
45 = k / 32 = k / 9
k=405
Now you have the full equation with proportionality factor.
y = 405 / x2
then, for x=5:
y = 405 / 52 = 405 / 25
y = 16.2
Answer:
9 units²
Step-by-step explanation:
we count the number of units for the length and Width.
Length = 3 units
Width = 3 units.
Area = 3 x 3 = 9 units²
