Angles a, b, and c are all 60°. A triangle’s angles add up to 180, and if the triangle is equilateral, each angle must be 60 (180/3). Angle d is 120° because b and d form a supplementary angle (180°), so 180-60 is 120. Angle e and f and 30°. Angles c and e form complementary angles (90°), so 90-60=30. For f, if the triangle adds up to 180, 180-120-30 = f. The 120 comes from d and the 30 comes from e. This leaves f as 30.

The rectangle below has an area of 15k^4 + 35k^3 + 20k^2. The width of the rectangle is equal to the greatest common monomial fa
RSB [31]

 The greatest common factor is the biggest number that divides evenly into each one of the numbers without a remainder...the only thing that's different about our situation is that we have variables in addition to regular number (but the same logic applies...we need to find the biggest variable that goes into k^4 , k^3 , and k^2 ).

 

The biggest number that goes into 15, 35 and 20 is the number 5. The biggest variable that goes into k^4 , k^3 , and k^2 is k^2

 

Combining the number and the variable, we get that the greatest common monomial factor is 5k^2

 

Since area is length x width, and we just figured out that width is 5k2 , all we have to do to find length is divide 15k4+35k3+20k2 by 5k2 , and we get that the length is 3k^2+7k+4

 

So the width is 5k^2 and the length is 3k2+7k+4

a sphere with a radius of 15cm has the same volume as a cylinder with a radius of 5 cm.what is the height od the cylinder
damaskus [11]

Answer:

180cm

Step-by-step explanation:

Vol of sphere = (4/3) pi r^3 and vol of cylinder = pi r^2 h

so

(4/3) pi 15^3 = pi (5)^2 h

(4/3) * 15^3 = 25h

h =  [(4/3) * 15^3 ] / 25  =  180 cm

QUESTION 1: A prism has a surface area of 100 in2. Which sentence describes the effect of measuring the surface area in square f
telo118 [61]
The answer is A in both cases. Changing the units does not change the measurement, only the number representing the measurement. (Some numbers are easier to work with than others, which is why some units are preferred for certain measurements.)


Question 1.
   A. <span>The surface area stays the same, but the number representing the surface area decreases.

Question 2.
   </span><span>A. The surface area stays the same, but the number representing the surface area increases.
