Answer: The number of copies of worksheet needs to be done = 90
Step-by-step explanation:
The expression used to evaluate the number of copies need to make of the worksheet (denoted as 'w') is given as 3(2w - 10).
If w=20, then the number of copies need to make of worksheet = 3(2(20)-10)
i.e. the number of copies need to make of worksheet= 3 (40-10)
i.e. the number of copies need to make of worksheet= 3 (30)
i.e. the number of copies need to make of worksheet= 3 x 30
i.e. the number of copies need to make of worksheet= 90
Hence, if w = 20, then the number of copies of worksheet needs to be done = 90

f the ratio 3x : 5y equals the ratio 7 : 11, then the ratio x : y equals what?
2.3 : 2.2
Given:3x : 5y and 7 : 11
Step-by-step solution:3x : 5y
7 : 11
To find x:
3x = 7
x = 7/3 (Bring 3 over to 7 to divide)
x = 2.3 OR 2/1/3
To find y:
5y = 11
y = 11/5 (Bring 5 over to 11 to divide)
y = 2.2 OR 2/1/5
So,
x = 2.3
y = 2.2
Therefore, the answer is:
x : y = 2.3 : 2.2
Use the graph to write a linear function that relates y to x.
Answer:
y = [tex]\frac{1}{3}[/tex] x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 6, 1) and (x₂, y₂ ) = (3, 4) ← 2 points on the line
m = [tex]\frac{4-1}{3+6}[/tex] = [tex]\frac{3}{9}[/tex] = [tex]\frac{1}{3}[/tex]
The line crosses the y- axis at (0, 3) ⇒ c = 3
y = [tex]\frac{1}{3}[/tex] x + 3 ← linear equation

Mr. Bradley purchased 20 trays of flowers. Each tray had 3 dozen flowers. Mr. Bradley's total for all the flowers was 273.60. All the flowers were the same price. How much did each flowers cost?
Answer: Each flower costs $0.38.
Step-by-step explanation:
1 dozen = 12 units
Flowers in each tray = 3 dozen = 3 x 12 = 36
Flowers in 20 trays = 20 x 36 = 720
Price of 20 trays = $ 273.60
Price of each flower = (Price of 20 trays ) ÷ (Flowers in 20 trays)
= 273.60 ÷ 720
= $ 0.38
Hence, each flower costs $0.38.

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 152,149,146
Answer:
the 30th term is 239
Step-by-step explanation:
The computation of the 30th term is as follows:
As we know that
a_n = a_1 + (n-1)d
where
a_1 is the first number is the sequence
n = the term
And, d = common difference
Now based on this, the 30th term is
= 152 + (30 - 1) × 3
= 152 + 29 × 3
= 152 + 87
= 239
Hence, the 30th term is 239

What is the distance between the points (2, 10) and (-6, 4) on the coordinate
plane?
O A. 10 units
B. 100 units
C. 5 units
D. 50 units
The distance between the points (2,10) and (-6,4) on the coordinate
plane is 10 units. The option A is correct option.
Given that the points are (2,10) and (-6,4) on the coordinate plane.
To find the distance between the given above points on the coordinate plane, the formula use:
[tex]D = \sqrt{((x_2 - x_1)^2 + (y_2 - y_1)^2)}[/tex]
Here, the value of [tex]x_1=2, \ x_2=-6, \ y_1=10[/tex] and [tex]y_2=4[/tex].
Therefore, the distance between the given points on the coordinate plane, put the values in the above given formula to get,
[tex]D = \sqrt{((-6 -2)^2 + (4 -10)^2)}\\D=\sqrt{(-8^2)+(-6)^2} \\D=\sqrt{64+36} \\D=\sqrt{100}\\ D=10 \ units[/tex]
Hence, The distance between the points (2,10) and (-6,4) on the coordinate plane is 10 units. The option A is correct option and the distance is 10 units.
