which of these expressions will return the same value for PV

Answer:

RECT and ANGL are similar triangles with a ratio of 9:16, and for TR, we have TR:24 in the ratio 9:16 so TR = 13.5

Answer:

Use Desmos to find the points:

Answer:

1 / 10

Step-by-step explanation:

Prob of  getting a quarter on the first draw  =  (5/10)

Prob of getting a nickel on the second draw  = (2/10)

So......the overall probability  is   (5/10) (2/10)  =  10 / 100  =    1 / 10

Took the test and this is the correct answer

Answer:

rational

Step-by-step explanation:

Any rational number can be expressed in the form

[tex]\frac{a}{b}[/tex] ← where a and b are integers

Given

[tex]\sqrt{4}[/tex] = - 2 or + 2

Since - 2 =  [tex]\frac{-2}{1}[/tex] and 2 = [tex]\frac{2}{1}[/tex] ← both in rational form, then

[tex]\sqrt{4}[/tex] is rational

Answer:The slope of a line characterizes the direction of a line. To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points.The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

Answer:

Step-by-step explanation:

Use SOH CAH TOA to recall how the trig functions fit on a triangle

SOH: Sin(Ф)= Opp / Hyp

CAH: Cos(Ф)= Adj / Hyp

TOA: Tan(Ф) = Opp / Adj

the above is really helpful if you don't have a brain.  :P

for 7 we only need Pythagoras's theorem, know it?

[tex]c^{2}[/tex] = [tex]a^{2}[/tex] + [tex]b^{2}[/tex]

out of curiosity.. does the above formula seem "impossible" ?  or does it make sense?

[tex]c^{2}[/tex] = [tex]12^{2}[/tex] + [tex]16^{2}[/tex]

[tex]c^{2}[/tex] = 144 + 256

[tex]c^{2}[/tex] = 400

c = [tex]\sqrt{400}[/tex]

c = 20

x= 20

for 8 we do need the above list of trig functions. we want to find the Hyp x and we know an angle and the adjacent side sooo use Cos .. b/c we can see it's got those parts in it

Cos(60) = 18 / x

I'll show you the algebra we need to use to get this formula so that we can find x

A = B / x  ( this is how it looks above )

x = B / A    , now just put in the parts

x = 18 / Cos(60)  now solve it w/ your calculator..  :P Cos(60) happens to be 1/2 so you could have done this w/o your calculator   :/

x = 36

there you go,   :)

Answer:

50

Step-by-step explanation:

as triangle is =180

then , 30 +100 +x =180

130 +x = 180

x= 180-130

=50

Answer:

50 degrees

Step-by-step explanation:

A triangle is 180 degrees and there is already a 30 and 100.

180-30-100=50.

Answer:

[tex]y=8x-781[/tex]

Here, [tex]x[/tex] represents temperature and [tex]y[/tex] denotes rate of chirping per minute.

Step-by-step explanation:

Let [tex]x[/tex] represents temperature and [tex]y[/tex] denotes rate of chirping per minute.

At [tex]106[/tex]°F, a certain insect chirps at a rate of [tex]67[/tex] times per minute.

Take [tex](x_1,y_1)=(106,67)[/tex]

At [tex]108[/tex]°F, they chirp [tex]83[/tex] times per minute.

Take [tex](x_2,y_2)=(108,83)[/tex]

Slope intercept form:

[tex]y-y_1=(\frac{y_2-y_1}{x_2-x_1})(x-x_1)[/tex]

[tex]y-67=(\frac{83-67}{108-106})(x-106)\\\\y-67=(\frac{83-67}{108-106})(x-106)\\\\y-67=(\frac{16}{2})(x-106)\\\\y-67=8(x-106)\\y-67=8x-848\\y=8x+67-848\\y=8x-781[/tex]

Answer:

Subtraction Property of Equality

Step-by-step explanation:

Given

[tex]-x + 1 = -4[/tex]

[tex]-x = -5[/tex]

Required

State which property is used

The word that describes the operation is; subtraction property of equality.

This property states that:

if [tex]x = y[/tex] then

[tex]x - a = y - a[/tex]

So, for the given  equation:

[tex]-x + 1 = -4[/tex]

When the subtraction property of equality is applied

[tex]-x + 1 - 1 = -4 - 1[/tex]

[tex]-x = -5[/tex]

So:

(a) Subtraction Property of Equality is correct

Answer:

45 songs in one year (12months)

Step-by-step explanation:

in one year she will have the following

12 x 3 = 36

+ 9 given

36+9 = 45 songs in one year

if it was decreasing to 11 months or 10 months etc

Then we use this formula

Birthday + (Amount monthly x No of month)

9 + (3 x 11) = 42 in 11 months

or 9 + (3 x 10) = 39 in 10 months
