Vilka [71]

Answer:

24 birds

Step-by-step explanation:

Let b represent the number of birds at the shelter on Wednesday. Then the cost of care for the 41 animals is ...

5b +7.5(41 -b) = 247.50

-2.5b +307.50 = 247.50 . . . . . simplify

-2.5b = -60 . . . . . . . . . . . . . . . . subtract 307.50

b = 24 . . . . . . . . . divide by -2.5

The number of birds at the shelter on Wednesday was 24.

Scientific Notation:<br> what’s (2.2 x 10 to the -4) - (3 x 10 to the 2)

Marrrta [24]

Answer:

$2.23\times10^4$

Step-by-step explanation:

In order to get the answer to this question you need to turn the scientific notations into standard form then subtract the two standard forms.

$(2.2\times10^{-4})-(3\times10^2)$

Turn the notations into standard form:

$2.2\times10^{-4} = .00022$

$3\times10^2=300$

$.00022-300=22300$

$=22300$

Turn into notation form:

$22300 = 2.23\times10^{4}$

Hope this helps.
