Suppose a video store charges nonmembers $4 to rent each video. A store membership costs $21 and members pay only $2.50 to rent each video. For what number of videos is the cost the same?
Answer:
You need to rent
14
videos, and you'll pay the same amount for both. Renting
15
will make the membership a better method of payment.
Explanation:
We can create an equation. Say the number of videos you rent is given by
n
. We can write that, if we rent
n
videos without membership, we'll have to pay
4
n
. If we rent the same amount of videos with membership, we'll have to pay
21
+
2.5
n
.
To find the value of
n
such that the amount you pay without membership is equal to the amount you pay with, we write:
4
n
=
21
+
2.5
n
1.5
n
=
21
n
=
21
1.5
n
=
14
You need to rent
14
videos, and you'll pay the same amount for both. Renting
15
will make the membership a better method of payment.

A 35-foot ladder is leaning against the side of a building and is positioned such that the base of the ladder is 21 feet from the base of the building. How far above the ground is the point where the ladder touches the building?
Answer:
height = 28 feet
Step-by-step explanation:
using the Pythagorean theorem:
height = 35² - 21²
height² = 1225 - 441 = 784
height = 28 feet

Step-by-step explanation:
I'm assuming you have learned basic trigonometry: SOH CAH TOA. In this diagram to find the angle x we are given the opposite side and the hypotenuse, therefore we will use SOH. sinθ = opp/hyp. Plugging in those values we get sinθ = 5/11 -> θ = sin⁻¹ (5/11) = 27.03569179° = 27°

Answer: 60 is the answer.
Step-by-step explanation: We can use the total sum, 180.
To get the missing angle, add the 2 angles, 60 and 60.
60 + 60 = 120.
Then subtract from 180.
180 - 120 = 60.
Hence, 60 is the answer.
Let me know if you have any questions.

write three to the power of two sevenths in radical form and explain?
Answer:
4782969
Step-by-step explanation:
Answer:
[tex]\sqrt[7]{3^{2}}[/tex]
Step-by-step explanation:
[tex]3^{2/7}[/tex]
^ That is 3 to the 2/7ths power. We know that. Now it needs to be in radical form. That takes a bit of thinking.
If you have a power that is less than one (like 1/2) it is can be written as a root. So say you're given [tex]2^{1/2}[/tex]. That is the same exact thing as saying [tex]\sqrt{2}[/tex]. It's the same thing. You can say it either way.
In the same way, a squared power, like [tex]2^{2}[/tex], is the same as representing it like a fraction, like [tex]2^{2/1}[/tex]. They both mean the same thing.
So by pointing these out, a fraction power = the power / the root.
If that makes sense.
So, with this in mind, let's look at what we have again.
[tex]3^{2/7}[/tex]
So we can split it up to say that 3 is raised to a 2nd power times a 1/7th power.
So we know what a 3 to the 2nd power is: [tex]3^{2}[/tex].
And since we have a fraction that's also included, we now know that is a root. So we can represent that like this: [tex]\sqrt[7]{3}[/tex].
But those two answers need to be combined. We can do that like this: [tex]\sqrt[7]{3^{2}}[/tex]
Answer: [tex]\sqrt[7]{3^{2}}[/tex]
So there it is! I hope that helped you!!

And thx
Answer:
9 (partly to do with the amount of sticks)
Hope this helps :)
Answer:
[tex]\frac{2}{5}[/tex]
Step-by-step explanation:
probability (P) is calculated as
P = [tex]\frac{favourableoutcome}{numberofpossibleoutcomes}[/tex]
Here favourable outcome is a purple brick
number of possible outcomes = 6 + 5 + 4 = 15
P(purple brick ) = [tex]\frac{6}{15}[/tex] = [tex]\frac{2}{5}[/tex]

Answer:
B
Step-by-step explanation:
Pythagorean theorem states that a²+b²=c²
Through observation, I assumed that 8 was the hypotenuse
I sqaured both the known lengths of the leg and hypotenuse and plugged them into the equation: a²+36=64
I subtracted 36 from 64 leaving me with 28=a²
Then in order to isolate the variable I had to apply square root to both values, cancelling the "²" and leaving me with √28=a
