suter [353]3 years ago
8 0

Answer:

257 is the answer

Step-by-step explanation:

If you take and divide 8.23 and 3.19 u come out with a big number but the first three are all that matter. then you need to subtract 8-5 and u get 2.579937 but since your exponent is only 10^3 you get 257.9937, but you can get rid of the numbers after 257.

11. On a math exam, two students scored 95, five students scored 87,
ivolga24 [154]

Answer:

About 76%.

Step-by-step explanation:

To find the average of numbers, you add all of the numbers together and divide the total by the number of numbers. In this case, your numbers would be 95 twice, 87 five times, 73 three times, 63 four times, and 40 once. The total number of numbers is 15, and the total of all of the exam scores if you add them up is 1136. Finally, you would divide 1136 by 15, which would be 75.7333333, which would be an average of about 76%.

What is the answer please
MrRissso [65]

Answer:

Step-by-step explanation:

ΔABE ~ ΔACD

In similar triangles, corresponding sides are in same ratio.

\dfrac{AE}{AD}=\dfrac{AB}{AC}\\\\\\\dfrac{12}{18}=\dfrac{9}{9+x}

\dfrac{2}{3}=\dfrac{9}{9+x}

Cross multiply,

2*(9+x) = 3*9

2*9 + 2*x = 27

18 + 2x = 27

       2x = 27 - 18

       2x = 9

          x = 9/2

x = 4.5

In the arithmetic sequence, -12, -17, -22, -27... which term has a value of -68?​
RSB [31]

Answer:

-68 is not a term in the given sequence

Step-by-step explanation:

The given sequence is -12, -17, -22, -27...

There is a common difference of d=-17--12=-5

The explicit rule for this sequence is f(n)=-12-5(n-1)

Or f(n)=-5n-7

To find the term that has a value of -68 we equate the explicit formula and solve for n.

 -68=-5n-7

 \implies -68+7=-5n

 \implies -61=-5n

n=\frac{61}{5} =12.2

The position should be a natural number.

Since n is a decimal, it tells us that -68 is not a term in the given sequence
