The point where two lines meet is known as an angle.

What are some applications of two column proofs?

A two-column proof moves a reader from premise to conclusion by using a table to give a logical argument and assigning each column to carry out a specific task.

Given the following angles from the diagram

m < 2 = m < 4

m < 2 = 100°

Prove that m<3 = 70⁰

m<2 = m<4 (vertically opposite angles)

m<3 and m<4 are supplementary, hence

m < 3 + m < 4 = 180°      ( linear pair )

Substitute m<4 = 110⁰ into the expression

m < 3 + 110 = 180

m < 3 = 180 - 110

m < 3 = 70

Step-by-step explanation:

Answer:

d = 4

Step-by-step explanation:

the nth term of an AP is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

given a₄ = 27 , then

a₁ + 3d = 27 → (1)

Also

a₁ + a₄ = 42 ← substitute a₄ = 27

a₁ + 27 = 42 ( subtract 27 from both sides )

a₁ = 15

substitute a₁ = 15 into (1)

15 + 3d = 27 ( subtract 15 from both sides )

3d = 12 ( divide both sides by 3 )

d = 4

A right angle is an angle of 90 degrees. A right angle is formed when two lines that are perpendicular to each other intersect. A right angle assumes the shape L.

Parallel lines are lines that do not meet or intersect at any point no matter how long they are extended. The sided of most quadrilaterals are parallel to each other and intersect at right angles. For example: squares and rectangles.

In our question, Jacqui will know that each pair of opposite sides are parallel since the corners are right angles, each pair of opposite sides will be perpendicular to the same line. As a result, each pair of opposite sides will be parallel.

The number of more drapery pieces than upholstery pieces does Brandon have is 2.03 pieces

Number of pieces of upholstery fabric = 23 3/5 ÷ 2 5/6

= 118/5 ÷ 17/6

= 118/5 × 6/17

= 708 / 85

= 8 28/85

Number of pieces of drapery fabric = 18 1/2 ÷ 2 5/6

= 37/2 ÷ 17/6

= 37/2 × 6/17

= 222/34

= 6 18/34

= 6 9/17

How many more drapery pieces than upholstery pieces does Brandon have = 708 / 85 - 222/34

= (24072-18204) / 2890

= 5,868 / 2890

During surgery, the average flow rate of the medications administered to the patient is 23 milliliters per hour.

Flow rate, denoted by Q, is defined as the amount of volume V flowing after time t. The formula for flow rate is given by:

Q = V/t

where V is volume and t is time.

For the two medication administered, given the flow rate and time, solve for the volume of each, and its total volume.

V = Q/t

1 : V1 = Q1t1 = (14ml/h)(150 minutes)(1hour/60 minutes)

V1 = 35 ml

2 : V2 = Q2t2 = (30 ml/h)(4hrs)

V2 = 120 ml

Solving for the average flow rate by dividing the sum of the volume to the sum of the time.

Qave = (V1 + V2)/(t1 + t2)

Qave = (35 + 120)ml/(2.5 + 4)hrs

Qave = 23.84615385 ml/h

Answer:

y = x + 1

Step-by-step explanation:

An x-intercept of 1 would have the coordinates (-1, 0)

Slope can be found with rise / run. In this case, rise (the number of units going up) would be 6, because 6 - 0 = 6. The run would also be 6 because 5 - (-1) = 6. Following the formula, the rise divided by the run, 6 / 6 = 1, so the slope is 1.

We also have to consider the y-intercept, hence the intercept in the name Slope Intercept Form ( y = mx + b). You can find this by substituting coordinates for y and x, using the slope, and solving for b.

Either (-1, 0) or (5, 6) can be used.

6 = 5(1) + b

6 = 5 + b

b = 1, because 5 + 1 = 6

0.01045 is rational. A rational number is any integer, fraction, terminating decimal, or repeating decimal.

[tex]\sqrt{\frac{3}{16} }[/tex] = Irrational number because it cannot be expressed as a fraction of two whole numbers and it has no accurate decimal equivalent.

[tex]\sqrt{48}[/tex] = The square root of 48 is not a rational number, as it cannot be expressed in the p/q form.

[tex]\sqrt{\frac{16}{81} }[/tex] = rational. The square root of (16/81) is the same as the square root of 16 divided by the square root of 81. You can divide the fraction inside the radical before or after you calculate the square root. The result will be the same.Here we first calculate the square root of the numerator and the square root of the denominator separately, and then we divide the two:  √16   √81  =    4   9  ≈  0.4444 Alternatively, we first divide 16 by 81 and then do the square root of the quotient:√16/81 ≈ √0.1975 ≈ 0.4444

Question 2:

[tex]\frac{\sqrt{6} }{\sqrt{5} }[/tex] = irrational. Irrational number because it cannot be expressed as a fraction of two whole numbers and it has no accurate decimal equivalent.

[tex]\frac{\sqrt{6} }{5}[/tex] = irrational number because it cannot be expressed as a fraction of two whole numbers and it has no accurate decimal equivalent.

[tex]\sqrt{30}[/tex] = the square root of 30 is not a rational number. It is an irrational number, as it cannot be expressed in the form of p/q.

[tex]\frac{\sqrt{5} }{6}[/tex] = irrational number, as it cannot be expressed in the form of p/q.

[tex]\frac{\sqrt{30} }{5}[/tex] = irrational since there is no exact square root for 30 and 5.

Taxi = 20n

The break-even point is when these are the same.

150 + 5n = 20n

n = 150/15 = 10

So with 10 boxes, it costs the same ($200) either way.

With 11 boxes, the Moving Company costs $205

With 11 boxes, the Taxi would cost $220.

It is cheaper to use the moving company with 11 or more boxes.

and the second equation is

3 x + 1 y = $ 8 -------(2)

We have to find the value of x and y by which we will get to know about the cost of each bag of gummy bears and chocolate bar respectively.

Now we have to multiply the second equation with 3

(3 x + 1 y = $8 ) *

we will get :

9 x + 3 y = $ 24 -------( 3)

After equating equations (1 ) and (3)

Then the area of these triangles is:

[tex]A = b_1*H/2 + b_2*H/2 = (b_1 + b_2)*H/2 = L*H/2[/tex]
