Answer:

A transversal is a line that intersects two or more coplanar lines at different points. Two angles are corresponding angles if they occupy corresponding angles. Two angles are alternate exterior angles if they lie outside the two lines on opposite sides of the transversal.on:

Answer:

The perimeter of Δ ABC is 20 + 2 $\sqrt{10}$ units ⇒ Last answer

Step-by-step explanation:

The perimeter of any triangle is the sum of the lengths of its three sides

The formula of distance between two points is $d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

In Δ ABC

∵ A = (3 , 4) , B = (-5 , -2) , C = (5 , -2)

∵ AB = 10 units

∵ AC = 2 $\sqrt{10}$

- To find its perimeter find the length of BC

∵ $x_{1}$ = -5 and $y_{1}$ = -2

∵ $x_{2}$ = 5 and $y_{2}$ = -2

- By using the formula above

∴ $BC=\sqrt{(5--5)^{2}+(-2--2)^{2}}=\sqrt{(5+5)^{2}+(-2+2)^{2}}$

∴ $BC=\sqrt{(10)^{2}+(0)^{2}}=\sqrt{100}$

∴ BC = 10 units

To find the perimeter add the lengths of the three sides

∵ P = AB + BC + AC

∴ P = 10 + 10 + 2 $\sqrt{10}$

- Add like terms

∴ P = 20 + 2 $\sqrt{10}$

The perimeter of Δ ABC is 20 + 2 $\sqrt{10}$ units

Jessica wants to calculate her grade in her accounting class.she has four test grades (82, 65, 71, and 77) and a homework grade

Aleks04 [339]

To solve the problem, get the percentage of each test by multiplying the score and the percentage then add it all up:

82 * .25 (highest test grade) + 65* .15 (lowest test grade) + 71*.20 (each test remaining) + 77*.20 (each test remaining) + 92*.20 (homework grade)

= 20.5 + 9.75 + 14.2 + 15.4 + 18.4 = 78.25 or 78% in whole number

Which diagram best shows how fraction bars can be used to evaluate One-half divided by one-fourth? A fraction bar labeled 1. Und

Leto [7]

Answer:

Step-by-step explanation:

The description is too ambiguous to reconstruct the diagram. You need to post the actual diagram.

That diagram is just one way to view division by a fraction. An easier way: DIVIDING by a fraction is the same as MULTIPLYING by the upside-down fraction. For example,

(1/2) ÷ (1/4) = (1/2) × (4/1) = 2

That doesn’t help you answer this particular question, though.

The graph represents the function where electricity usage in kilowatts per hour of a clock radio varies directly with the number

geniusboy [140]

Answer:

Reasonable estimation for constant of variation is 0.25 kWh per day.

Step-by-step explanation:

We are given the following information in the question:

The graph represents the function where electricity usage.

Electricity usage in kilowatts per hour of a clock radio varies directly with the number of days.
The x-axis shows the number of days and usage in kilo-watt per hour is showed on the y-axis.
Some coordinates of the graph are: (0,0), (2,0.5) and (6,1.5)

Formula for constant of variation:

$\displaystyle\frac{y_2-y_1}{x_2-x_1}$

Putting the values from the coordinates (2,0.5) and (6,1.5), we get:

$\displaystyle\frac{1.5-0.5}{6-2} = \frac{1}{4} = 0.25\text{ kilowatt-hours per day}$

Hence, reasonable estimation for constant of variation is 0.25 kWh per day.
