Bev earns $2 a week for taking out her neighbor’s trash cans. Complete the table of values. Then state the domain and range.

Eduardwww [97]

Domain : $\{1,2,3,4\}$

Range: $\{2,4,6,8\}$

Explanation:

It is given that Bev earns $2 a week.

Thus, for n number of weeks, we shall multiply $2 with n.

Where $n=1,2,3,4$ is the number of weeks.

For 1 week, Bev earns $2n=2(1)=2$ ⇒ $2

For 2 weeks, Bev earns $2n=2(2)=4$ ⇒ $4

For 3 weeks, Bev earns $2n=2(3)=6$ ⇒ $6

For 4 weeks, Bev earns $2n=2(4)=8$ ⇒ $8

Thus, we can see that the domain is the number of weeks.

Hence, Domain : $\{1,2,3,4\}$

Also, the money earned is the range.

Hence, Range: $\{2,4,6,8\}$

The Jones family went to a play and paid $74 for 2 adults and 2 children. The Tucker family went to the same play and paid $86 f

Sveta_85 [38]

The answer is $25.

x - the price of an adult ticket
y - the price of a child ticket

The Jones paid $74 for 2 adults and 2 children: 2x + 2y = 74
The Tuckers paid $86 for 2 adults and 3 children: 2x + 3y = 86

This is the system of two equations:
2x + 2y = 74
2x + 3y = 86
____
Multiply the first one by (-1)
2x * (-1) + 2y * (-1) = 74 * (-1)
2x + 3y = 86
____
-2x - 2y = -74
2x + 3y = 86
____
Sum the equations:
2x - 2x + 3y - 2y = 86 - 74
y = 12
____
Substitute y in the first equation to find x:
2x + 2 * 12 = 74
2x + 24 = 74
2x = 74 - 24
2x = 50
x = 50/2
x = 25

So, the price of the adult ticket is $25 and the price of the child ticket is $12.

What is the volume of this triangular Pyramid photo attached

storchak [24]

To find the volume of a triangular pyramid, the formula is:

$V=\frac{1}{3}(Area\text{ }of\text{ }thebase)(height)$

So we start by finding the area of the base, which is in the shape of a right triangle in this case.

The area of a right triangle is equal to 1/2 x base x height.

$\begin{gathered} A=\frac{1}{2}bh \\ \\ A=\frac{1}{2}(5)(6) \\ \\ A=15\text{ square feet} \end{gathered}$

We use this area to find the volume.

$\begin{gathered} V=\frac{1}{3}Ah \\ \\ V=\frac{1}{3}(15)(6) \\ \\ V=30\text{ cubic feet} \end{gathered}$

The volume of the triangular pyramid is 30 cubic feet.

Find the measurement parallelogram. I need help please, thank you. I need explanation

blondinia [14]

Answer:

2.) 145°

4.) 50°

Step-by-step explanation:

2.) First find the measure of Angle Y, since they are supplementary;

∠Z + ∠Y = 180

35 + ∠Y = 180

∠Y = 180 - 35

∠Y = 145°

So ∠X would be 145° as well

4.) First find the measure of Angle F, since they are supplementary;

∠C + ∠F = 180

130 + ∠F = 180

∠F = 180 -130

∠F = 50°

So ∠E would be 50°

(I didn't explain it much in detail, since this question is similar to the previous that i answered :)

Hope this helps!
