Answer: b = p - a -c

Step-by-step explanation:

p= a + b + c Solving for b means getting b on one side by itself.

p = a + b + c To solve for b first subtract a from both sides to get,

-b -b

p - a = b + c Now subtract c from both sides to get

-c -c

p - a - c = b

b = p - a -c

A survey showed that 35% of the students prefer plain white milk over chocolate milk. If the school has 1200 students. How many

Pani-rosa [81]

780 students prefer chocolate milk.

Step-by-step explanation:

Let,

the total percentage = 100%

Students who prefer plain white milk = 35%

Students who prefer chocolate milk = 100 - 35 = 65%

Number of students = 1200

No. of students who prefer chocolate milk = 65% of total students

No. of students who prefer chocolate milk = $\frac{65}{100}*1200$

No. of students who prefer chocolate milk = $\frac{78000}{100}\\$

No. of students who prefer chocolate milk = 780

780 students prefer chocolate milk.

PLEASE PLEASE PLEASE HELP I NEED THIS BY 8:00pm!

Likurg_2 [28]

Answer:

1. $85

2. $90.10

3.$108.12

4.$54.06

Step-by-step explanation:

100-15=85 (15% of 100 is 15)

6 percent of 85 is 5.10. So 85 + 5.10=90.10

20 percent of 90.10 is 18.02. So add that to the total. 90.10+18.02=108.12

Now divide by 2 to get how much they each will pay 108.12/2 = 54.06

For an Isosceles triangle of base b and congruent sides, x units long, what is the range of angle measures for the angle measure

olga2289 [7]

Answer:

the desired range is 0° < angle < 180°

Step-by-step explanation:

If 2x were just slightly less than b, then the angle opposite the base would be just less than 180 degrees.

The larger the value of x, the further the intersection of the two congruent sides is moved away from the base b. The angle between these two congruent sides would approach but never equal zero.

Thus, the desired range is 0° < angle < 180°
