the answer is 16 because .80 times 20 is 16
Answer:
The pair of triangles that are congruent by the ASA criterion isΔ ABC and Δ XYZ.
The pair of triangles that are congruent by the SAS criterion is Δ BAC and ΔRQP.
Step-by-step explanation:
Two triangles are congruent by ASA property if any two angles and their included side are equal in both triangles .In triangles Δ ABC and Δ XYZ the equal side 5 is between the two equal angles. So these triangles are congruent by ASA criterion.
Two triangles are congruent by SAS if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle .In triangles Δ BAC and ΔRQP. the included angles A and Q are equal and hence the triangles are congruent by SAS criterion.
Answer: C
Step-by-step explanation:
divide 342 by 7 and round to the nearest whole number
Answer:
1st sphere has r1 = 6
=> Surface area S1 = 4 x pi x r1^2 = 4 x pi x 6^2 = 144pi
=> Volume V1 = (4/3) x pi x r1^3 = (4/3) x pi x 6^3 =288pi
2nd sphere has r1 = 15
=> Surface area S1 = 4 x pi x r1^2 = 4 x pi x 15^2 = 900pi
=> Volume V1 = (4/3) x pi x r1^3 = (4/3) x pi x 15^3 =4500pi
=> S1/S2 = 144pi/900pi = 0.16
=> V1/V2 = 288pi/4500pi = 0.064
Hope this helps!
