If m∠A = m∠B and m∠A + m∠C = ∠D, then m∠B + m∠C = ∠D Which property is shown?

Answers

Answer 1

Answer:

Substitution Property

Step-by-step explanation:

So we know that:

[tex]m\angle A=m\angle B[/tex]

And we also know that:

[tex]m\angle A+m\angle C=\angle D[/tex]

And by using a specific property, we get that:

[tex]m\angle B+m\angle C=\angle D[/tex]

Essentially, we substituted B for A.

So, this is an example of the substitution property, where if two sides/angles are congruent, we can substitute them for each other.

BASEBALL The formula for a pitcher's earned run average, or ERA, is a = 9r/p. In
this formula, a is the earned run average, r is earned runs, and p is innings pitched.
b. Find the earned runs for a pitcher with an ERA of 2.63 who has pitched
89 innings.

Answers

Answer:

To find a baseball pitcher's earned run average you can use the formula EI 9r

To find a baseball pitcher's earned run average (ERA), you can use the formula Ei=9r, where E represents ERA, i represents number of innings pitched, and r represents number of earned runs allowed.

9x^2 - 16 = (px+t)(px-t) both p and t are constants. Which of the following could be the value of p

Answers

Answer:

p = 3

Step-by-step explanation:

9x² - 16 ← is a difference of squares and factors in general as

a² - b² = (a + b)(a - b)

Thus

9x² - 16

= (3x)² - 4²

= (3x + 4)(3x - 4)

Compare with (px + t)(px - t)

then p = 3

TOPIC: similtaneous linear equations

p1 + 2q = 3,
p - 2q = 3

Answers

Answer:

q-0

p-3

Step-by-step explanation:

there are two ways to solve elimination or substitution method I'll use the latter

so take the second equation and find an expression equal to p

p-2q=3

p=2q+3

substitute the above expression in the first equation

(2q+3)1+2q=3

open brackets

2q+3+2q=3

collect like terms

4q+3=3

solve

4q=0

q=0

substitute q in any equation you want I'll choose the second

p-(2×0)=3

p-0=3

p=3

Answer:

p = 3 ; q = 0

Step-by-step explanation:

In this linear pair of eqn. in 2 variables , they have a unique solution i.e. they will have only single solution . We know that

[tex]p + 2q=3[/tex] & also [tex]p -2q=3[/tex] . So, we can also equate them as :-

[tex]p + 2q = p-2q[/tex] (∵ Both the eqn. have 3 in their right hand side product )

Solving the eqn. gives,

[tex]=> 2q + 2q = p-p\\=> 4q=0\\=>q=0[/tex]

Putting the value of q in any one of the linear eqn gives ,

[tex]p+2q=3\\=> p+2(0)=3\\=>p+0=3\\=>p=3[/tex]

It can be done as follows :

[tex]5p^3-10p^2+3p-6=(5p^3+3p)+(-10p^2-6)[/tex]

Answer:

38.81%

Step-by-step explanation:

Circle area = п r ²

п = 3.14

r = 4 cm

Circle area = 3.14 * (4cm)²

Circle area = 3.14* 16cm²

Circle area = 50.24cm²

Triangle area = (heigth*width)/2

heigth = 2.5 + 4 = 6.5cm

width = 3 + 3 = 6cm

triangle area = (6.5cm*6cm)/2

triangle area = 39cm²/2

triangle area = 19.5cm²

then:

the probability that a randonly select point whitin the circle falls in the shaded area is:

19.5/50.24 = 0.3881     (aprox)

0.3881*100 = 38.81%

I'm working with varibles on both sides. This is math, also algebra 1. The expression is... 8-4a=16-8a I'm so confused on which side to subtract from. I tried doing +8 on both sides. Please help.

Answers

Answer:

a=2

Step-by-step explanation:

You can have "a" on both sides and still get an answer easily. You start off by adding 8a to the right. That makes 8+4a=16. You then subtract 8 from 16 and get 4a=8. Divide by 4 to get your answer. You get a=2

A=2, you add 8a to both sides and subtract 8 and then divide by 4

I go and come with a strange liberty in Nature, a part of herself. As I walk along the stony shore of the pond in my shirt sleeves, though it is cool as well as cloudy and windy, and I see nothing special to attract me, all the elements are unusually congenial to me. The bullfrogs trump to usher in the night, and the note of the whippoorwill is borne on the rippling wind from over the water. Sympathy with the fluttering alder and poplar leaves almost takes away my breath; yet, like the lake, my serenity is rippled but not ruffled. These small waves raised by the evening wind are as remote from storm as the smooth reflecting surface. Though it is now dark, the wind still blows and roars in the wood, the waves still dash, and some creatures lull the rest with their notes. The repose is never complete. The wildest animals do not repose, but seek their prey now; the fox, and skunk, and rabbit, now roam the fields and woods without fear. They are Natures watchmen, links which connect the days of animated life. . . . Some of my pleasantest hours were during the long rain storms in the spring or fall, which confined me to the house for the afternoon as well as the forenoon, soothed by their ceaseless roar and pelting; when an early twilight ushered in a long evening in which many thoughts had time to take root and unfold themselves. . . .
