Mathematics
1 answer:
pashok25 [27]3 years ago

Answer and Step-by-step explanation:

<u>The second option (5d = 55)</u>

This works because Arianna wants to <u><em>divide</em></u> the amount of dominos to her <em><u>5</u></em> friends. We do this by dividing 55 by 5.

d will then equal 11 (d = 11).

Estimate the result by rounding the numbers to the second decimal before performing the operation. Then also round your answer t
umka2103 [35]

Answer:

40615

Step-by-step explanation:

Note, rounding off decimals involves observing if the said decimal is up to the value of 5. If it is, then it can be rounded up, if not, its rounded off.

Since we need to round the numbers to the second decimal before performing the operation, we will have, 8123÷0.2

Note, 8123 has no decimal so we ignore

But 0.211 has a second decimal which is the first 1 so because it's not up to 5, we round it off to 0.

Hence we have 8123 ÷ 0.2= 40615.0

Since our answer has no decimal, we leave it like that.

0.00952 in scientific notation
goldenfox [79]

Answer:

hopefully tht example will help u

Step-by-step explanation:

To change 0.0002 to scientific notation, move the decimal to the right 4 places so that you get 2. The exponent on the base 10 will be -4 because the decimal was moved to the right 4 places. So 0.0002 in scientific notation is 2×10−4.

If theta is a positive acute angles find theta when <br>2 sin^2 theta + 3 cos theta =3​
MArishka [77]

Answer:

Theta = 0, 60 degrees.

Step-by-step explanation:

2 sin^2 theta + 3 cos theta = 3​

Using the identity sin ^2 theta = 1 - cos^2 theta :

2(1 - cos^2 theta) + 3 cos theta  = 3

2 - 2cos^2 theta) + 3 cos theta  = 3

2 cos^2 theta - 3 cos theta   + 3 - 2 = 0

2 cos^2 theta - 3 cos theta   + 1 = 0

(2 cos theta - 1)(cos theta - 1) = 0

cos theta = 1/2 , cos theta = 1

Theta = 60 degrees or theta = 0
