Mazyrski [523]

Answer:

9

Step-by-step explanation:

Let corn tortillas be represented by c, flour tortillas be represented by f and the total number of packages be t

such that

t = c + f .... eq 1

ratio of c to t = 7 : 16 = 7/16

Therefore, t = 16, c = 7

substitute the value of t in eq 1

16 = 7 + f

f = 16 - 7

f = 9

Answer:

$\huge\boxed{9}$

Step-by-step explanation:

$\sf (2^8 * 3^{-5} * 6^0)^{-2 } (\frac{3^{-2}}{2^3} )^4*2^{28}$

Rule of exponents $a^0 = 1$ , $1/a^m = a^{-m}$

=> $\sf 2^{8*-2} * 3 ^{-5*-2} * 3 ^{-2}* 2^{-3*4} * 2^{28}$

=> $\sf 2 ^ {-16} * 3^{10} * 3^{-8} * 2 ^{-12}* 2^{28}$

Combining same bases

=> $\sf 2 ^ {-16} * 2 ^{-12}* 2^{28}* 3^{10} * 3^{-8}$

When bases are same , powers are to be added

=> $\sf 2 ^{-16-12+28} * 3^{10-8}$

=> $\sf 2^{-28+28} * 3^2$

=> $\sf 2^0 * 3^2$

=> $\sf 3^2$

=> 9

20.7 degrees C
Step-by-step explanation:
Here's the easiest way to solve. Grab a calculator, or a piece of paper. (its simple math) SOOOO, The start is 19.4. Then, it rises 3.8. So add that to 19.4. That gives you 23.2, BuT, it falls again, back down 2.5 degrees. so take 23.2, and subtract 2.5 from it. That should give you 20.7 degrees.
