√20 the prime factors are 2, 2, 5 so
-2 * √4 *√5
-2*2*√5
-4√5 is the first part ,
now for √125, use prime factorization ,
all prime factors that make up 125 is
5, 5, 5 so √125 can be separated to √25√5 and √25 = 5 so the second part is 5√5.
now -4√5 - 5√5 = -9√5.
therefore answer is -9√5

Write the algebraic expression described. Recall that two angles are complementary if their sum is 90 degrees. If one angle meas
igor_vitrenko [27]

Answer:

C = 90 - d

Step-by-step explanation:

We know that the sum of complementary angles is 90 degrees

i.e.

Angle 1 + angle 2 = 90°

As it is stated in the question that one angle is d then

d+C = 90

where C is complementary angle of C

This can also be written as:

C = 90 - d ..

A manufacturer makes bags of popcorn and bags of potato chips. the average weight of a bag of popcorn is supposed to be 3.02 oun
Dovator [93]
If these were the given choices:
A. The popcorn bag assembly line is closer to the specifications given because its z-score is closer to the standard mean than the potato chip bag assembly line.
B. The popcorn bag assembly line is closer to the specifications given because its z-score is further from the standard mean than the potato chip bag assembly line.
C. The potato chip bag assembly line is closer to the specifications given because its z-score is closer to the standard mean than the popcorn bag assembly line.
D. The potato chip bag assembly line is closer to the specifications given because its z-score is further from the standard mean <span>than the popcorn bag assembly line.

My answer is: </span>A. The popcorn bag assembly line is closer to the specifications given because its z-score is closer to the standard mean than the potato <span>chip bag assembly line.

Given:
Ave.weight of a bag of popcorn - 3.02 oz
allowable deviation - 0.02 oz

Ave. weight of a bag of potato chips - 5.03 oz
allowable deviation - 0.04 oz

Actual weight of bag of popcorn - 3.03 oz
Actual weight of bag of potato chips - 5.06 oz 

The allowable deviation is very minimal in a bag of popcorn thus its z-score is nearer to the standard mean as compared to the bag of potato chips. </span>
