The tuition costs, C, for a local community college are modeled by C(h) = 250 + 200h, where h represents the number of credit hours taken. The local state university has tuition costs, S, modeled by the function S(h) = 300 + 180h. How many credit hours will a student have to take for the two tuition costs to be equal? Round the answer to the nearest tenth of an hour. 250 + 200h = 300 + 180h 250 + 200h = 300 + 180h − 180h − 180h 250 + 20h = 300 h = credit hours

What is the answer for 3{5[10+5(500-100)+399]}

Answers

Okay. Handle 500-100 first. That brings it to 3{5[10+5(400)+399]}. Next, Handle 5(400). That brings you to 3{5{10+2,000+399]}. Then handle all the addition. That leads to 3[5(2,409)]. Next, configure 5(2409). That leads to 3(12045). Then do that one which ends as 36,135 for a final answer.

Adam is going to cook a turkey for 14 people and wants to allow ¾ lb of turkey for each person. 1lb = 450 g
How much would a turkey cost for 14 people? £

Answers

Missing info:
Turkey Sizes: 
small - 2kg - 3.9kg 
medium - 4kg - 5.4kg 
large - 5.5kg - 7.2kg 
extra large - 7.3kg - 9.2kg 

Turkey Prices: 
Small / Medium - £5.99 per kg 
Large / Extra Large - £4.99 per kg 

3/4 lb x 14 persons = (3*14)/4 = 42/4 = 10.5 lbs

1 lb = 450 grams

10.5 lbs * 450grams/lb = 4,725 grams

1 kg = 1000 grams

4,725 grams * 1kg/1000 grams = 4725 kg / 1000 = 4.725 kg.

4.725 kg is under the Medium size of the Turkey.

Medium sized turkey costs £5.99 per kg.

4.725 kg * £5.99 per kg = £28.30

A turkey would cost  £28.30 for 14 people.

Find the value of k such that (k, k) is equidistant from (−2, 0) and (0, 5). k =____

Answers

To find the value of k such that (k, k) is equidistant from (-2, 0) and (0, 5), we can use the distance formula.

The distance between two points (x1, y1) and (x2, y2) is given by the formula:

Distance = √((x2 - x1)² + (y2 - y1)²)

Let's calculate the distances from (k, k) to (-2, 0) and (0, 5) and set them equal to each other:

√((k - (-2))² + (k - 0)²) = √((k - 0)² + (k - 5)²)

Simplifying this equation:

√((k + 2)² + k²) = √(k² + (k - 5)²)

Squaring both sides of the equation to eliminate the square roots:

(k + 2)² + k² = k² + (k - 5)²

Expanding and simplifying:

k² + 4k + 4 + k² = k² + k² - 10k + 25

2k² + 4k + 4 = 2k² - 10k + 25

Rearranging terms:

4k + 4 = -10k + 25

Combining like terms:

14k = 21

Dividing both sides by 14:

k = 21 / 14

Simplifying the fraction:

k = 3 / 2

Therefore, the value of k that makes (k, k) equidistant from (-2, 0) and (0, 5) is k = 3/2.

Answers

(-x+7)/(2x+4)+(2x+5)/(2x+4) =(-x+7+2x+5)/(2x+4)=( x+12)/(2x+4)
(-x+7)/(2x+4) + (2x+5)/(2x+4)=(x+12)/(2x+4)
