Answer: By moving from sea level to Mexico City air pressure is reduced by 25%.
Step-by-step explanation:
Hi, to answer this we have to apply a decrease rate formula
P0 (1-r)^x
Where:
p0= initial pressure
r = decrease rate. (0.4 = 0.4/100=0.004 decimal form)
x = feet (hundredths, since the air pressure decays every 100 feet we have to divide the input value by 100)
Replacing with the values given
P0 (1- 0.4/100)^(7340/100) =
P0 (0.996)^73.4 =
P0 ( 0.75)=
The air pressure at Mexico City compared to the sea level is 75% (0.75 x 100 =75%)
To obtain the percent decrease
100% -75% =25%
There are two ways in
finding the place value of 2 in 5,670,249,114
First by breaking down the numbers:
5,670,249,114 = 5,000,000,000 +
600,000,000 + 70,000,000 + 200,000
+ 40, 000 + 9,000 + 100 + 10 + 4
which means the Value of 2
is 200, 000<span>2. Second, by using the ones words:
5,670,249,114 = 5 billion + 6 hundred million + 70 ten million + 2 hundred thousand + 4 ten thousand + 9
thousands + 1 hundreds + 1 tens + 4 ones
which means the Value of 2 is 2
hundred thousand
</span>
It would be, 33%.
Hope this helps!
Answer:30.48
Step-by-step explanation:
Answer:
centre = (4,-2)
radius = 3
Step-by-step explanation:
The centre-radius form of the circle equation is in the format
(x – h)² + (y – k)² = r²,
with the centre being at the point (h, k) and the radius being "r"
Given in the question an expression which can be write as
<h3> (x – 4)² + (y – (-2))² = 3²</h3>
So, by translating we can say that
centre = (4,-2)
and
radius = 3
