Hi!

$13m=12-m$

$13m+m=12-m+m$

$14m=12$

$\frac{14m}{14}=\frac{12}{14}$

$m=\frac{6}{7}$

Explanation<em><u>: First you had to do is add m to from both sides. It gave us 13m+m=12-m+m. Then you can simplify, it gave us 14m=12. You can also divide by 14 from both sides. It gave us 14m/14=12/14. And the answer is going to be m=6/7 is the right answer. Hope this helps! And thank you for posting your question at here on Brainly. And have a great day! -Charlie</u></em>

( Hint)

To find the curve of best fit, you will need to do exponential regression. Press STAT, then right arrow to highlight CALC, and then press 0:ExpReg . The correlation coefficient is r, which is 0.994 in this case. That means that the equation is a 99.4% match to the data.

Which value is closest to the perimeter of the window

Eddi Din [679]

Answer:

9.82 feet

Step-by-step explanation:

the perimeter of the window is the circumference of a semi-circle with a diameter of 5

P = (πd)/2 (divided in half because it's only half a circle)

P ≈ 3.14(3.5) which is approx 11

11 is closest to 9.82

Explain how to do this math problem all the way threw 6times2 and 7/10

Anestetic [448]

So first multiply the whole numbers.
6x2=12
Now multiply 6 and 7. When multiplying a fraction like this, do the numerator ONLY. So it ends up being 42/10. That can be turned to a mixed number. To do that, find out how many times 10 can go into 42. The highest whole number is 4.
10x4=40 and there's 2 left over. So make it 2/10 which can be simplified to 1/5
Now add.
12+4=16+1/5= 16 1/5

The elevation of a small submarine changes by -3/8 mile after each exploration. After how many explorations will the submarine's

diamong [38]

Answer:

It is after 4 explorations that the submarine's elevation would have changed by -3/2 miles

Step-by-step explanation:

From the question,

The elevation of the submarine changes by -3/8 mile after each exploration.

To determine the number of explorations it will take for the submarine's elevation to have changed by -3/2 miles, we will divide -3/2 miles by the number of miles the elevation of the submarine changes per exploration (that is, -3/8 mile),

That is,

-3/2 miles ÷ -3/8 mile

= $-\frac{3}{2} \div -\frac{3}{8}$

= $-\frac{3}{2} \times -\frac{8}{3}$

= $\frac{24}{6}$

= 4

Hence, it is after 4 explorations that the submarine's elevation would have changed by -3/2 miles.
