The scientific notation:

$a\cdot10^k\\\\1\leq a < 10,\ k\in\mathbb{Z}$

$7\underbrace{5,000,000,000.}_{\leftarrow10}=7.50000000000\cdot10^{10}=7.5\cdot10^{10}$

Answer:

distance is 6.4 units

Step-by-step explanation:

use a^2+b^2=c^2 to find the hypotenuse which is the distancr

you can count the sides base is 4 and height is 5 Square the numbers

16+25= c^2

41=c^2

find the square root of 41 to get rid of the squared

which is 6.40 so 6.40= c and c is the distance

$\frac{1}{ cos^{2} \alpha } + \frac{1}{ sin^{2} \alpha } = \frac{ sin^{2} \alpha + cos^{2} \alpha }{ sin^{2} \alpha * cos^{2} \alpha } = \frac{1}{sin^{2} \alpha * cos^{2} \alpha}$

Answer:

244.

Step-by-step explanation:

We have been given that Allie wants to subtract 341-97 mentally. First she adds 3 to 97 to get 100. We are asked to determine Allie's next step and the difference of both numbers.

Allie's next step would be add 3 to 341 because adding same quantity to both numbers will keep the ratio same.

After adding 3 to 341 Allie would get $3+341=344$ .
