Determine whether or not the relation is a function. Please help asap

Answer/Step-by-step explanation:

Q=number of quarters; D=number of dimes

Q+D=30

D=30-Q . Use this to substitute for D below

$0.10D+$0.25Q=$5.85 . Substitute for D from above.

$0.10(30-Q)+$0.25Q=$5.85

$3.00-$0.10Q+$0.25Q=$5.85

$0.15Q=$2.85

Q=19

ANSWER 1: There were 19 quarters.

D=30-Q=30-19=11

ANSWER 2: There were 11 dimes.

CHECK:

$0.10D+$0.25Q=$5.85

$0.10(11)+$0.25(19)=$5.85

$1.10+$4.75=$5.85

Answer:

Step-by-step explanation:

Given, (In picture)

Parallel sides of the trapezoid = 6.5 in,15.1 in

Height of the trapezoid = 5 in

We know that,

Area of a trapezoid,

= 1/2 × Sum of parallel sides × Height

Therefore,

Area of the given trapezoid

[tex] = \frac{1}{2} \times (6.5 \: in \: + \: 15.1 \: in) \times \: 5 \: in[/tex]

[tex] = \frac{1}{2} \times 21.6 \: in \: \times 5 \: in[/tex]

= 10.8 in × 5 in

[tex] = 54 \: {in}^{2} (ans)[/tex]

Step-by-step explanation:

Question 5,

First multiplying with, (-3/4) ÷ (6) × (1 5/9) (mixed number)

=(-3/4) ×(1/6) × (14/9)

=(1/8) × (14/8)

=(-7/36)

So, (a/b) = (-7/36)

Therefore, a = -7

From the information given, the inequality that models the situation is:

[tex]4x + 3y \leq 60[/tex]

The cold water flows at a rate of 4 gallons per minute, hence, the amount after x minutes will be of: [tex]4x[/tex]

The hot water fills at a rate of 3 gallons per minute, hence, the amount after y minutes will be of: [tex]3y[/tex].

The total amount is the sum of these amounts, hence:

[tex]T = 4x + 3y[/tex]

It holds a maximum of 60 gallons, hence:

[tex]T \leq 60[/tex]

[tex]4x + 3y \leq 60[/tex]

Answer:

Step-by-step explanation:

the sum of the interior angles of a triangle is 180°,

so 5x+3x+2x=180°

5x+3x+2x=180°

10x = 180°

x = 18°

find angle L

3 * 18 = 54°

Answer:

a) is not a triangle.

b)

Okay, so I used this method to determine if the measurements will make a triangle.

a+b has to be greater than c. 7+2= 9. So 9 is greater than c

a+c has to be greater than b.  7+ 5= 12. which is greater than b

c+b has to be greater than a. 5+ 2 is 7. which is equal to a.

That means it would not make a triangle. Because c+b must be GREATER than a.
