Jimmy purchased 15 tickets to a concert and spent $140. He purchased some children's tickets and some adult tickets. The childre

fiasKO [112]

Answer:

Jimmy purchased 8 of the children's ticket and 7 of the adult's ticket.

Step-by-step explanation:

Let c = children tickets

Let a = adult tickets

Given the following data;

Number of tickets = 15

Total amount spent = $140

Cost of each children ticket = $7

Cost of each adult ticket = $12

*Translating the word problem into an algebraic equation (system)*

For the total number of tickets;

$c + a = 15$ .........equation 1

For the total amount spent;

$7c + 12a = 140$ ..........equation 2

*Solving the linear equation by using the substitution method*

Making c the subject in equation 1:

$c = 15 - a$ .......equation 3

Substituting "c" into equation 2;

$7(15 - a) + 12a = 140$

Simplifying the equation, we have;

$105 - 7a +12a = 140$

$105 + 5a = 140$

Rearranging the equation, we have;

$5a = 140 - 105$

$5a = 35$

$a = \frac {35}{5}$

a = 5 (For the $12 adult ticket).

To find the number of children tickets;

Substituting "a" into equation 3;

$c = 15 - 7$

c = 8 (For the $7 children ticket).

Which expressions can be used to find m∠ABC? Check all that apply.

valina [46]

Answer:

$\cos^{-1}(\frac{6.3}{9.8})$

$\sin^{-1}(\frac{7.5}{9.8})$

Step-by-step explanation:

Recall the mnemonics SOH-CAH-TOA

The sine ratio is the length of the opposite side expressed over the hypotenuse.

$\sin m\angle ABC=\frac{7.5}{9.8}$

Take the sine inverse of both sides to get;

$m\angle ABC=\sin^{-1}(\frac{7.5}{9.8})$

The cosine ratio is the length of the adjacent side expressed over the hypotenuse.

$\cos m\angle ABC=\frac{6.3}{9.8}$

Take the cosine inverse of both sides to get;

$m\angle ABC=\cos^{-1}(\frac{6.3}{9.8})$

If we are given the value of α. How can we find the value of β?

Cloud [144]

Answer:

β = 140 - α

we know that the "missing" angle is 40° since 40 + 140 = 180

we also know that the total sum of angles in a triangle is 180

so β = 180 - 40 - α

or β = 140 - α
