Answer:

25 days

Step-by-step explanation:

lets the blank = x

Convert 72% to decimal: 0.72

How many and what type of solutions does the equation have?

ella [17]

Answer: C

Step-by-step explanation:

Simplify to 4x^2 + 12x + 5 = 0 so that all the terms are on one side.

Do a part of the quadratic formula to see.

You only need to do the $-b^2-4ac$ part. If it is negative, that means there are irrational solutions. If it is positive, it has two solutions. If it is 0, it has 1 solution.

$12^2-4(4)(5) = 64$

It is positive so it has two solutions.

Find all the missing elements

Roman55 [17]

Answer:

$b = 5.5$

$c = 11.2$

Step-by-step explanation:

Given:

A = 96°

B = 25°

C = 59°

a = 13

Required:

b and c

SOLUTION:

Use Sine Rule to find the measure of a and b, respectively.

✍️Thus, to find b, use,

$\frac{a}{sin(A)} = \frac{b}{sin(B)}$

Plug in the values

$\frac{13}{sin(96)} = \frac{b}{sin(25)}$

Multiply both sides by sin(25)

$\frac{13}{sin(96)} \times sin(25) = \frac{b}{sin(25)} \times sin(25)$

$\frac{13 \times sin(25)}{sin(96)} = b$

$b = 5.5$ (nearest tenth)

✍️To find c, use,

$\frac{a}{sin(A)} = \frac{c}{sin(C)}$

Plug in the values

$\frac{13}{sin(96)} = \frac{c}{sin(59)}$

Multiply both sides by sin(59)

$\frac{13}{sin(96)} \times sin(59) = \frac{c}{sin(25)} \times sin(59)$

$\frac{13 \times sin(59)}{sin(96)} = c$

$c = 11.2$ (nearest tenth)

Can someone please help me with the equation part of this question?

Let the price of a student ticket be t. That makes the price of an adult ticket t + 3, as adult tickets are three more dollars than student tickets. Now we have:

student ticket = t
adult ticket = t + 3

To model the scenario that Mr. Williams bought 7 student tickets and 6 adult tickets, set the sum of the products of those numbers and the ticket costs equal to 83 (the cost of all tickets combined) and solve algebraically for t.

83 = 7t + 6(t + 3)
83 = 7t + 6t + 18
83 = 13t + 18
65 = 13t
5 = t

Remember, t represents the cost of one student ticket, thus one student ticket costs 5 dollars, and one adult ticket costs 5 + 3 dollars or 8 dollars.

Answer:
The price of one adult ticket is $8.
