A total of 328 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was three times the
number of adult tickets sold. How many adult tickets were sold?

Answers

Answer:

246 adult tickets were sold

Step-by-step explanation:

System of equations:

Variables:

x = number of adult tickets sold

y = number of student tickets sold

There were a total of 328 tickets sold, thus:

x + y = 328

The number of student tickets sold was three times the number of adult tickets sold, thus:

y = 3x

Substituting in the first equation:

x + 3x = 328

Simplifying:

4x = 328

Dividing by 4:

x = 328/4

x = 82

y = 3*82= 246

246 adult tickets were sold

3b^2-22b-16

Answer:

3b^2 -22b -16

Step-by-step explanation:

(3b+2)(b-8)

FOIL

first :3b*b = 3b^2

outer : 3b *-8 = -24b

inner: 2*b = 2b

Two chemical plants, one at Macon and one at Jonestown, produce two types of fertilizer, low phosphorus (LP) and high phosphorus (HP). At each plant, the fertilizer is produced in a single production run, so the two types are produced in fixed proportions. The Macon plant produces 1 ton of LP and 3 tons of HP in a single operation, and it charges $600 for what is produced in one operation, whereas one operation of the Jonestown plant produces 1 ton of LP and 1 ton of HP, and it charges $1,000 for what it produces in one operation. If a customer needs at least 100 tons of LP and 180 tons of HP, how many production runs from each plant should be ordered to minimize the cost.

Step-by-step explanation:

A person places $85800 in an investment account earning an annual rate of 8.5%,

compounded continuously. Using the formula V = Pert, where V is the value of the

account int years, P is the principal initially invested, e is the base of a natural

logarithm, and r is the rate of interest, determine the amount of money, to the nearest

cent, in the account after 9 years.

Answers

Answer:

$184383.7

Step-by-step explanation:

We are given that

Principal, P=$85800

Rate of interest, r=8.5%=0.085

Time, t=9 years

We have to find the amount of money after 9 years

[tex]V=Pe^{rt}[/tex]

Using the formula

[tex]V=85800e^{0.085\times 9}[/tex]

[tex]V=184383.7[/tex]

Hence, the amount of money after 9 years=$184383.7

Answers

Answer:

x = 10°, y = 20°

Step-by-step explanation:

Fill in the missing angle measures, 20° and 70°.

7x = 180 - 90 - 20

7x = 70

x = 10

2y = 180 - 7x - 5x - 20 = 40

y = 20

X=10
Y=20

Explanation-you would take 20+90 then subtract that from 180 which gives you 70 and 7x10 is equal to 70. 70+110=180. If x=10 then 5x would give you 50, then you add 20 and get 70. Then you add another 70 because the angle between the green line and black line is equal to 7x. This would give you 140. So 2y would have to be 2(20) which give you the remaining 40.
