Then, inches to foot (12 inches in 1 foot)
So, 140/12 which is 11 2/3 feet
Now 11 2/3 * 2.50 for each foot is 29.16 (rounded down, 29$) (not sure if this is right btw)

Given tangent, ZN, to the circle and the arc [tex]\widehat{ZMB}[/tex] = 280°, we have that
the angle formed by the chord BZ and the tangent ZN, ∠BZN is 50°

A tangent to the circle O = ZN
[tex]m \widehat{ZMB}} = \mathbf{280^{\circ}}[/tex]
Required:
Angle ∠BZN
Solution;
Please find attached the drawing of the circle and tangent
From the drawing, we have;
∠BOZ = 360° - 280° = 80°
ΔBOZ is an isosceles triangle, which gives;
∠BZO = ∠ZBO
[tex]\angle BZO = \dfrac{(180^{\circ}- 80^{\circ}) }{2} = \mathbf{50^{\circ}}[/tex]
∠OZN = 90° (by definition of a tangent)
∠OZN = ∠BZO + ∠BZN
∠BZN = ∠OZN - ∠BZO
Which gives;
∠BZN = 90° - 40° = 50°

Q1: No solutions
Q2: x=2, y=-2
Q3: x=1, y=4
Step-by-step explanation:
Q1: Found out 0y = 18 which is impossible therefore no solution.
Q2:
In the first equation: [tex]2x - 4y = 12[/tex]
Let's express x in terms of y by changing the subject. Follow my steps.
[tex]2x = 12+4y[/tex]
[tex]x = \frac{12+4y}{2}[/tex]
Now let's put the x above into the second equation: [tex]-14x-4y=-20[/tex]
It becomes: [tex]-14(\frac{12+4y}{2})-4y=-20[/tex]. Follow my steps.
[tex]-7(12+4y)=-20+4y[/tex]
[tex]-84-28y=-20+4y[/tex]
[tex]-32y=64[/tex]
[tex]y=-2[/tex]
Put y = -2 into the first equation:
[tex]2x-4(-2)=12[/tex]
[tex]2x+8=12[/tex]
[tex]2x=12-8[/tex]
[tex]2x=4[/tex]
[tex]x=2[/tex]
Q3:
Multiply the first equation by 3 and the second equation by 7, so that both are 21x.
1st equation:
[tex]3(7x-3y)=3(-5)[/tex]
[tex]21x-9y=-15[/tex]
2nd equation:
[tex]7(3x+2y) = 7(11)[/tex]
[tex]21x+14y = 77[/tex]
We can now substract the 2nd equation with the 1st equation so that both 21x cancels out and only the variable y remains.
[tex]21x-9y-(21x+14y)=-15-77[/tex]
[tex]21x-9y-21x-14y=-92[/tex]
[tex]-23y=-92[/tex]
[tex]y=4[/tex]
Put y = 4 into the second equation to find x.
[tex]3x+2(4)=11[/tex]
[tex]3x+8=11[/tex]
[tex]3x=11-8[/tex]
[tex]3x = 3[/tex]
[tex]x=1[/tex]

By the time the blizzard was over the temperature had dropped from
17°F to -6°F This was a drop of how many degrees?
Answers
Answer:
23
Step-by-step explanation:
To get to 17 degrees, you need to add 6 to -6 to get to 0.
And to get to 17 from 0, you need to add 17.
So then you add 6 and 17 together.
6+17=23
6+-6=0
6+17=23
This was a drop of 23 degrees.
A recipe for a cookie batch calls for 5/8 cup of flour. There are three and three-fourths cups of flour in a bag in the cupboard. How many batches of cookies can you make?
Answers
Answer:
So a batch is 5/8
There are THREE 3/4th cups of flour in the cupboard.
So 3 three fourths so basically
3/4 * 3 = 9/4 or
3/4 + 3/4 + 3/4 = 9/4
9/4 and each batch is 5/8.
9/4 ÷ 5/8 = 72/20 or 3 1/10

The dimensions on paper are 1.992ft by 5.976ft with a scale factor of 7.53
Step-by-step explanation:
The first step will be to find the diagonal of the rea life mural.
We can use Pythagoras' Theorem to do this.
Diagonal = [tex]\sqrt{15^2 +45^2 }[/tex] =47.43 feet.
Now we have the real-life diagonal, we will now relate the diagonal of the painting outside with the one on paper. We can do this by dividing the two diagonals.
This will be 47.43 / 6.3 units = 7.53.
The scale factor is 7.53
To get the dimensions of the length and the breadth on paper, we divide the outside dimensions by the scale factor.
This will be
Length = 15/ 7.53 = 1.992
Breadth = 45/7.53 = 5.976
Therefore, the dimensions on paper are 1.992ft by 5.976ft with a scale factor of 7.53

How do i write 2x+3y=24 as slope-intercept form?
Answers
Answer:
y = - [tex]\frac{2}{3}[/tex] x + 8
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 )
Given
2x + 3y = 24 ( subtract 2x from both sides )
3y = - 2x + 24 ( divide all terms by 3 )
y = - [tex]\frac{2}{3}[/tex] x + 8 ← in slope- intercept form
The equation 2x+3y=24 in the slope-intercept form can be written as [tex]y = -\frac{2}{3}x+8[/tex]
From the question,
We are to write the given equation in the slope-intercept form
The slope-intercept form of an equation of straight line is written as
y = mx +c
To write the equation, 2x+3y=24, in the slope-intercept form, we will make y the subject of the equation
[tex]2x+3y=24[/tex]
First, subtract 2x from both sides of the equation
That is,
[tex]2x -2x +3y = 24 -2x[/tex]
This becomes
[tex]3y = 24 -2x[/tex]
Now, divide both sides by 3
[tex]\frac{3y}{3} =\frac{24-2x}{3}[/tex]
∴ [tex]y = \frac{24}{3}-\frac{2x}{3}[/tex]
[tex]y = 8-\frac{2}{3}x[/tex]
In the slope-intercept form, we get
[tex]y = -\frac{2}{3}x+8[/tex]
Hence, the equation 2x+3y=24 in the slope-intercept form can be written as [tex]y = -\frac{2}{3}x+8[/tex]
