Answer:
y ≈ 5.2
Step-by-step explanation:
∠ F = 180° - (42 + 48)° ← sum of angles in a triangle
∠ F = 180° - 90° = 90°
Thus Δ DEF is right at F
Using the sine ratio in the right triangle
sin48° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{DF}{DE}[/tex] = [tex]\frac{y}{7}[/tex] ( multiply both sides by 7 )
7 × sin48° = y , then
y ≈ 5.2 ( to the nearest tenth )

Jillian buys 3.6 meters of fabric. The fabric costs $5.75 for each meter.
How much does Jillian spend for the fabric?
A. $9.35
B. $17.25
C. $18.57
D. $20.70
Total amount spend by Jillian for the fabric is $20.7.
What is division?Division is a process of splitting a number into two or more equal parts.
Given is that Jillian buys 3.6 meters of fabric. The fabric costs $5.75 for each meter.
Assume that Jillian spend ${x} for the fabric.
Total length of fabric bought by Jillian = 3.6 meters
Cost of 1 m of fabric = $5.75
So, we can write the total cost of fabric as -
x = 3.6 x 5.75
x = 20.7
Therefore, total amount spend by Jillian for the fabric is $20.7.

Which ordered pair describes a point that is located 5 units to
the right of the origin and 2 units below the x-axis?
Answer:
(5,-2)
Step-by-step explanation: the right of the origin is a positive number and below is negative there fore if you go right 5 it would be 5 and down 2 would be -2 .
The ordered pair describes a point that is located 5 units to the right of the origin and 2 units below the x-axis are (5, -2).
What is the coordinate grid?A coordinate grid has two perpendicular lines, or axes labeled just like number lines. The horizontal axis is usually called the x-axis. The vertical axis is usually called the y-axis. The point where the x- and y-axis intersect is called the origin.
Given a statement for coordinates a point that is located 5 units to
the right of the origin and 2 units below the x-axis,
so the left side of the x-axis is the negative value of x and the right side of x-axis is the positive values of x.
5 units to the right, which is the coordinate of x is 5
and the upper of x-axis is the positive side of the y-axis and down of x-axis is the negative side of the y-axis,
2 units below the x-axis, which is coordinate of y is -2
point is (5, -2).
Hence the coordinates of points are (5, -2).

Answer:
Step-by-step explanation:
∠B and ∠D are same side interior angles and are supplementary angles ( they add up to 180°) because AB ║CD are cut by transversal BD
5x +4x = 180
9x =180
x= 20
∠B = 5*20 =100°

What is the vertex for the quadratic
y = 2(x-3)^2 - 4? Type as (h.k)
Answer:
(3,-4)
Step-by-step explanation:
You can find the vertex where x = -b/2a
To find the values of a and b, it would be easier to write the equation in standard form, which is y = ax^2 + bx + c
y = 2(x^2 - 6x + 9) - 4
y = 2x^2 - 12x + 18 - 4
y = 2x^2 - 12x + 14
In this equation, a = 2 and b = -12.
So let's plug that into x=-b/2a
x = -(-12)/2(2)
x = 12/4
x = 3
Now we have the x, we can just plug that into the original equation and get the y coordinate for the vertex.
y = 2(x - 3)^2 - 4
y = 2(3 - 3)^2 - 4
y = -4
