Catherine has $54. She plans to spend more than $20 of the money for a painting canvas. The rest will go toward paints. Each tub

Mariana [72]

There is a fixed cost of $20 at the beginning, then each of the x tubes of paint costs $8.50. This means that all the tubes of paint will cost 8.5x. The total cost (including the canvas) will be 20 + 8.5x. The maximum amount is 54, so the inequality is:
20 + 8.5x <= 54
Solving gives:
8.5x <= 34
x <= 4
So the maximum number of tubes of paint is 4.

Please help me on this problem !

Answer:

8.485

Step-by-step explanation:

This is a right isosceles triangle, thus the angles for side a and b are going to be the same, all the angles must all add up to equal 180, thus 180 - 90 = 90 then 90 ÷ 2 = 45 so we now know that angle a and b are 45°, with that said we can now find out what the vale of x is.
Calculates 2 sides based on 3 given angles and 1 side.

a = c·sin(A)/sin(C) = 8.48528 = 6 $\sqrt{2}$

b = c·sin(B)/sin(C) = 8.48528 = 6 $\sqrt{2}$

Area = $\frac{ab·sin(C)}{2}$ = 36

Perimeter p = a + b + c = 28.97056

Semiperimeter s = $\frac{a + b +c}{2}$ = 14.48528

Height ha = $\frac{2×Area}{a}$ = 8.48528

Height hb = $\frac{2×Area}{b}$ = 8.48528

Height hc = $\frac{2×Area}{c}$ = 6

Median ma = $\sqrt{(a/2)^{2} + c2 - ac·cos(B)}$ = 9.48683

Median mb = $\sqrt{(b/2)^{2} + a2 - ab·cos(C)}$ = 9.48683

Median mc = $\sqrt{(c/2)^{2} + b2 - bc·cos(A)}$ = 6

Inradius r = $\frac{Area}{s}$ = 2.48528

Circumradius R = $\frac{a}{2sin(A)}$ = 6

Find the range of the data.<br><br> 41, 64, 97, 12, 8, 8

enot [183]

Answer:

Step-by-step explanation:

<h2>How do you find the range of a data set?</h2><h3><u>first put you're data set from lowest to highest, then subtract your highest by your lowest value</u></h3><h3>Data:</h3>

8, 8, 12, 41, 64, 97

<u>We can clearly see that our highest value is 97, and our lowest in 8.</u>

<h3>97 - 8 = <u>89</u></h3><h2>Hence our range of data is 89.</h2>
