Answer:
them some expensive pencils
Answer:
D
Step-by-step explanation:
It has the correct ration of red wax to white wax.
If for every 12 mL of red wax there's 5mL of white wax, with 36 mL, which is triple the amount a pink crayon calls for, then we also have to triple the white wax. 5 mL times 3 is 15 mL. Therefore, D is correct.
Answer:
1. 3, and 2. m x n
Step-by-step explanation:
1. for an upper triangular 2x2 matrix i.e. (a,0,c,d), three (03) unknown elements a, c, and d are needed to be specified.
2. for m x n matrix, m*n elements are needed to be specified.
I remember foing this i think it is x>453
I am not 100 percebt sure
The formulas for arc length and area of a sector are quite close in their appearance. The formula for arc length, however, is related to the circumference of a circle while the area of a sector is related to, well, the area! The arc length formula is

. Notice the "2*pi*r" which is the circumference formula. The area of a sector is

. Notice the "pi*r squared", which of course is the area of a circle. In our problem we are given the arc length and the radius. What we do not have that we need to then find the area of a sector of the circle is the measure of the central angle, beta. Filling in accordingly,

. Simplifying by multiplying by 360 on both sides and then dividing by 36 on both sides gives us that our angle has a measure of 60°. Now we can use that to find the area of a sector of that same circle. Again, filling accordingly,

, and

. When you multiply in the value of pi, you get that your area is 169.65 in squared.
