The student population at a university is currently 400. The expected annual rate of increase is predicted to be 0.02. What will the population be in 5 years? Round your answer to the nearest whole number

Answers

Answer 1
Answer:

Answer: 440

Step-by-step explanation:

Current population =400

0.02 increase= 2% increase

2% increase per year= 2/100 ×400 = 8

For 5 years, 8× 5= 40 additional students

Population in 5years will be current population + expected population = 400+ 40= 440

Evaluate the square root of x^2 - 5x when x = 7. Round your answer to the nearest hundredth

Answers

X^2-5x, given x=7,

(7)^2-5(7)=14

sqrt(14)=3.74
OK, 72−(5)(7)=14
Its 14 because you plug in the sevens then you get 49-35 which is 14. Hope this answer helps you and mark as brainliest! :)

7k-6k=16 solve for k

Answers

K=16.
7(16)-6(16)= 16
K = 16. You subtract the 7k and 6k. Then divide 16 by 1 and 1k by 1. The 1k cancels out so it’s just 16

△XYZ is mapped to △X'Y'Z' using the rules (x, y)→(x+5, y−3) followed by (x, y)→(−x, −y) . Which statement describes the relationship between △XYZ and △X'Y'Z'?


△XYZ is congruent to △X'Y'Z' because the rules represent a translation followed by a rotation, which is a sequence of rigid motions.

△XYZ is not congruent to △X'Y'Z' because the rules do not represent a sequence of rigid motions.

△XYZ is congruent to △X'Y'Z' because the rules represent a rotation followed by a reflection, which is a sequence of rigid motions.

△XYZ is congruent to △X'Y'Z' because the rules represent a rotation followed by a translation, which is a sequence of rigid motions.

Answers

Given that △XYZ is mapped to △X'Y'Z' using the rules (x, y)→(x+5, y−3) followed by (x, y)→(−x, −y) .

We know that (x,y) => (x+h,y+k) type operation represents translation so rule (x, y)→(x+5, y−3)  will cause translation.

We know that (x,y) => (-x,-y) type operation represents rotation about origin so rule (x, y)→(−x, −y) will cause rotation.

So combining both results and comparing with given choices. we find that only 1st choice "△XYZ is congruent to △X'Y'Z' because the rules represent a translation followed by a rotation, which is a sequence of rigid motions."

is correct.

MIDDLE SCHOOL

The seventh grade class supplied bags of snacks and beverages for the school dance They supplied19 more beverages than bags of snacks The dance was supplied with a total of 371 items.

Answers

Answer:

The number of number of bags of snacks = m  = 176

The number of beverages supplied = m + 19  = 176 +9 = 185

Step-by-step explanation:

Let us assume the number of bags of snacks = m

So, the number of beverages supplied = m + 19

Total number of items supplied  =  371

⇒ Number of (snacks + beverages) supplied=  371

⇒   m + (m +19)  = 371

or, 2 m = 371 - 19 =  352

or, m =  352 / 2 = 176  

⇒  m  = 176

Hence the number of number of bags of snacks = m  = 176

So, the number of beverages supplied = m + 19  = 176 +9 = 185
