You estimate that there are 45 marbles in a jar. The actual amount is 82 marbles. Find the percent error. Round to the nearest t
Nataly_w [17]

Answer:

45.1

Step-by-step explanation:

The original amount is 82

But the wrong amount is 45

So we will have to calculate the percentage for the error

82-45

37

So %error= 37/82 ×100

=3700/82

=45.121~45.1( to nearest tenth)

So the final answer is 45.1%

A theater has 28 rows of 38 seats downstairs and 14 rows of 26 seats upstairs.How many seats does the theater have?
Triss [41]
For downstairs- 28 x 38= 1064

For upstairs- 26 x 14= 364

All together- 1064 + 364= 1428


So.... 1428 seats in total.

Hope this helped! :)

UNO [17]

Answer:

y=-6.6 and y=10.6

Step-by-step explanation:

The given ellipse has equation:

\frac{(y-2)^2}{64}+\frac{x^2}{9}=1.

The center of this ellipse is (h,k)=(0,2)

We use the equation: a^2-b^2=c^2 to determine the foci.

\implies 64-9=c^2

\implies 55=c^2

\implies c=\pm \sqrt{55}

The directrices are given by y=k\pm\frac{a^2}{c}

y=2\pm\frac{64}{\sqrt{55}}

y=2\pm8.6

y=2-8.6 and y=2+8.6

The equation of the directrices are:

y=-6.6 and y=10.6

The correct answer is D
