Answer:
Each shirt costs 12$
Step-by-step explanation:
Simple steps :)
1. Times 4 by 5 which equals 20
2. Next subtract 20 by 44 which is 24
3. Now take 24 and divide by 2 (Since there are 2 shirts) this is you answer
One shirt costs 12$
Hope this helped have a GOOD day :)
Answer:
x = - 6
Step-by-step explanation:
Equation
1/3 * (-9x +12) = 22 Multiply both sides by 3
Solution
3 * 1/3(-9x + 12) = 22*3
- 9x + 12 = 66 Subtract 12 from both sides.
-9x = 66 - 12 Combine
-9x = 54 Divide by -9
x = 54/-9
x = - 6
1. Rewrite the expression in terms of logarithms:

Then differentiate with the chain rule (I'll use prime notation to save space; that is, the derivative of <em>y</em> is denoted <em>y' </em>)




2. Chain rule:




Since
, we can cancel one factor of sine:

3. Chain rule:




4. If you're like me and don't remember the rule for differentiating logarithms of bases not equal to <em>e</em>, you can use the change-of-base formula first:

Then

So we have




and we can use the double angle identity and logarithm properties to condense this result:

5. Differentiate both sides:





6. Same as with (5):






7. Looks like

Compute the second derivative:


Set this equal to 0 and solve for <em>x</em> :





Answer:
A. 7,6,14
Step-by-step explanation:
Rules for side lengths of triangle.
1. Any side should be less then the sum of the other two angles.
2. The same side should be greater than the subtraction of the other side lengths(bigger side - smaller side)
A.
7 < 6+14 . Correct
7> 14-6 . Incorrect
This cannot be a solution (impossible)
B.
4<4+4 . Correct
4>4-4 . correct
This is a solution (equilateral triangle)
C.
6<6+2 . Correct
6>6-2 . Correct
This is a solution (isosceles triangle)
D.
7<8+13 . Correct
7>13-8 . Correct
This is a solution (scalene triangle)

Ratio of their volumes = a³ : b³
Ratio of their surface areas =
<u>Step-by-step explanation:</u>
Two square pyramids are similar with their edges are in the ratio of a : b.
Volume of a square pyramid with edge and h = a is given by the formula,
=
= 
Volume of a square pyramid with edge b and h = b is given by the formula,
=
= 
Ratio of their volumes = a³ : b³ since h/3 gets cancelled.
Total surface area of square pyramid with the edge a =

Total surface area of square pyramid with the edge b =

Ratio of the surface area =
