Answer:
4 songs: $3.96 8 songs: $7.92
Step-by-step explanation:
- Divide to find out how much it costs for 1 song.
5.94 / 6 = 0.99 <u>Each song costs $0.99</u>
- Now multiply $0.99 by (number of songs)
- 0.99 x 4 = 3.96
- 0.99 x 8 = 7.92
The problem statement says "the graph is shown," but you haven't shared it. Please do that if possible. Thank you.
<span>Heather was asked to graph 2x + 4y = 12 by using slope and y-intercept.
We can quickly put this into slope-intercept form:
12 - 2x
Subtract 2x from both sides: 2x - 2x + 4y = 12 - 2x => y = ------------
4
In simplest form, this is y = 3 - (1/2)x, or (-1/2)x + 3. The slope is -1/2 and the y-intercept is (0,3).</span>
67, 66, 67, and 45, respectively.
Step-by-step explanation:
We apply the pythagorean theorem on ABC.
AC^2=11^2+60^2 = 3600 + 121 = 3721
AC=61
Which means that sin(BAC) = 60/61.
However, sin^2(BAC) + cos^2(BAC)=1.
3600/3721 + cos^2(BAC) = 3721/3721.
cos^2(BAC) = 121/3721.
BAC is an acute angle so the cos is a positve number.
cos(BAC) = 11/61.
Lastly, x/60 = cos(BAC), so x= 660/61
The mean of data is Sally's prediction which is congruent to her cat's weigh:
mean=average weight= (13.5+12.5+10.5+11.2+11.2+10.8+9.5+13.4+11.5+11.8)/10= 11.59 lb is the answer
