Answers

Answer 1

Answer:

a≤9

Step-by-step explanation:

Answer 2

Answer:

a ≤ 9

Step-by-step explanation:

2a-5 ≤ 13

add +5 then divide both sides by 2 to isolate the variable

step 1: 2a-5+5 ≤ 13+5 → 2a ≤ 18

step 2: 2a/2 ≤ 18/2 → a ≤ 9

A craft club makes 95 identical paperweights to sell. They collect $230.85 from selling all of the paperweights. If the profit the club collects is two times as much as the cost to make each one, what does it cost the club to make each paperweight?

Answers

Answer: It costs $1.22 to make each paperweight.

Step-by-step explanation:

Given : Selling price of 95 identical paperweights = $230.85

Then, Selling price of 1 paperweight = (Selling price of 95 identical paperweights) ÷ 95

= $ (230.85 ÷ 95) = $ 2.43

Now, selling price of each paperweight = 2 x ( cost of each paperweight)

⇒ cost of each paperweight = (selling price of each paperweight ) ÷ 2

⇒ cost of each paperweight = $ 2.43 ÷ 2 = $ 1.215 ≈ $ 1.22

Hence, it costs $1.22 to make each paperweight.

Distance Formula: [tex]\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Step-by-step explanation:

Step 1: Define

Point (5, 1)

Point (9, -6)

Step 2: Identify

x₁ = 5, x₂ = 9

y₁ = 1, y₂ = -6

Step 3: Find distance d

Simply plug in the 2 coordinates into the distance formula to find distance d

Substitute in points [DF]:                    [tex]\displaystyle d = \sqrt{(5-9)^2+(1+6)^2}[/tex]

Here,

two points are (5,1) and (9,-6)

So,

x1=5

x2=9

y1=1

y2= -6

we know that,

Distance formula:- [tex]\bold{D=\sqrt{(x_2 - x_1 )^2+(y_2 - y_1)^2} }[/tex]

According to the question,

Distance between (5,1) and (9,-6)

[tex]\bold{D=\sqrt{(5-9)^2+(1-\{-6\})^2} }[/tex]

[tex]\bold{D=\sqrt{(5-9 )^2+(1+6)^2} }[/tex]

so,

option C is correct..

Determine the intercepts of the line.
y- 6 = 4(x + 5)
y-intercept:

x-intercept:

Answers

Answer:

x intercept: -13/2

y intercept: 26

Step-by-step explanation:

x intercept of the line is the point where y = 0

Substitute y = 0 into the expression;

0 - 6 = 4(X+5)

-6 = 4x + 20

4x = -6-20

4x = -26

x = -26/4

x = -13/2

y intercept is the point where x = 0

y - 6 = 4(0+5)

y-6 = 20

y = 20+6

y = 26

Answer:

The value of x in terms of b is: [tex]\mathbf{x=-\frac{6}{2b}}[/tex]

The value of x when b is 3 is: x = -1

Step-by-step explanation:

We are given the function: [tex]-2(bx-5)=16[/tex]

First we need to find

The value of x in terms of b

We need to find value of x

[tex]-2(bx-5)=16[/tex]

Multiply -2 with terms inside the bracket

[tex]-2bx+10=16[/tex]

Subtract 10 from both sides

[tex]-2bx+10-10=16-10\\-2bx=6[/tex]

Divide both sides by -2b

[tex]\frac{-2bx}{-2b}=\frac{6}{-2b}\\x=-\frac{6}{2b}[/tex]

So, The value of x in terms of b is: [tex]\mathbf{x=-\frac{6}{2b}}[/tex]

The value of x when b is 3

We have the equation for the value of x in terms of b:

[tex]\mathbf{x=-\frac{6}{2b}}[/tex]

Put b = 3

[tex]x=-\frac{6}{2(3)}\\x=-\frac{6}{6}\\x=-1[/tex]

So, The value of x when b is 3 is: x = -1

The measure of an interior angle of a regular polygon is 174. Find the number of sides in the polygon.

Answers

Answer:

60 sides

Step-by-step explanation:

The formula for the sum of the interior angles of a polygon with n sides is 180(n -2). The problem also tells you that each angle is 174, so the sum of the interior angles would also be 174n.

Then, you get the equation

180(n - 2) = 174n

180n - 360 = 174n

6n = 360

n = 60 sides.

the measure of one angle of the angles in a linear is 30 less than one-half the measure of the other angle. Find the measure of each angle.

Answers

Answer:

140° and 40°

Step-by-step explanation:

let x be one angle then the other is [tex]\frac{1}{2}[/tex] x - 30

Since the angles are a linear pair, theis sum is 180° , then

x + [tex]\frac{1}{2}[/tex] x - 30 = 180, that is

[tex]\frac{3}{2}[/tex] x - 30 = 180 ( add 30 to both sides )

[tex]\frac{3}{2}[/tex] x = 210 ( multiply both sides by 2 to clear the fraction )

3x = 420 ( divide both sides by 3 )

x = 140

and [tex]\frac{1}{2}[/tex] x - 30 = [tex]\frac{1}{2}[/tex] (140) - 30 = 70 - 30 = 40

The 2 angles are 140° and 40°

The perimeter of a triangular shaped garden is 24 feet. The third side is one more than four times the first side. The second side is three more than the first side
What is the length of the longest side of the garden?

Answers

Answer:

14 1/3 feet

Step-by-step explanation:

let 's' = shortest side

let '4s + 1' = longest side

let '3 + s' = middle side

s + 4s + 1 + 3 + s = 24

6s + 4 = 24

6s = 20

s = 20/6 or 3 1/3

longest side: 4 · 10 + 1

If b = 110 what is the value of g
IM BEING TIME PLZ HELP THANK YOU

Answers

Answer:

its 120 degrees

Step-by-step explanation:

add up all the know angles (110.60,70) then take that number and subtract it from 360, (360 is the number you get if you add all sides four sided shape)  

The measure of the value of g is, 60° by definition of alternate angles of parallel lines.

What are Parallel lines?

Parallel lines are those lines that are equidistance from each other and never intersect each other. and, Parallel lines are lines in a plane that are always the same distance apart and never intersect. But Perpendicular lines are lines that intersect at a right (90 degrees) angle.

We have to given that;

Two parallel lines are shown in image.

And, The measure of b = 110°

Here,

By the figure, we have;

A transverse line cut the parallel lines.

And, Both angles 60 and g are alternate angles of parallel lines.

We know that;

The alternate angles of parallel lines are equal to each other.

Hence, The value of measure of g = 60°

So, We get by the definition of alternate angles of parallel lines,

⇒ The measure of g = 60°
