3i = 105
To make i by itself, divide both sides by i.
i = 35
There you have it, 35 is the answer.
Answer:
Step-by-step explanation:
- Number of dimes = d, each d = 10 c
- Number of quarters = q, each q = 25 c
- Total = $2 = 200 c
<u>Equations according the given:</u>
<u>Solve for q by substitution:</u>
- 10(q + 6) + 25q = 200
- 10q + 60 + 25q = 200
- 35q = 140
- q = 140/35
- q = 4
<u>Find the value of d:</u>
Nathaniel has 10 dimes and 4 quarters
Answer:
31.5
Step-by-step explanation:
Hi, there.
For this question, we can apply the Pythagorean theorem
.
I'm sure you've seen this equation before, and they kind of tried to trip you up with this problem. Trust me, it's easier than it looks. Let's break it down.
Lengths a and b both have the value of 48, which means that the value s in
is 48, because the length of the hypotenuse is the same as the length and height squared multiplied by 2.
Plug in the value for c: ![a^2 + b^2 = (\sqrt{2s^2})^2](https://tex.z-dn.net/?f=a%5E2%20%2B%20b%5E2%20%3D%20%28%5Csqrt%7B2s%5E2%7D%29%5E2)
Plug in the value for s:
![(\sqrt{2(48^2)})^2](https://tex.z-dn.net/?f=%28%5Csqrt%7B2%2848%5E2%29%7D%29%5E2)
Do the innermost exponents first:
![(\sqrt{2(2304)})^2](https://tex.z-dn.net/?f=%28%5Csqrt%7B2%282304%29%7D%29%5E2)
The square root symbol and the power of 2 cancel each other out, so we are left with:
s =
, so the hypotenuse is 4608 inches.
Answer:
PST=80
Step-by-step explanation:
So we know that angle R=130 and because this is a parallelogram we can assume angle SPQ also equals 130 and knowing that we can find that angle RQP and RSP are equal both equal to 50 and since we know that RSP=50 we know SPT is also 50 because of alternate angles. SPT is an equilateral triangle so we also know that angle T is 50 degrees. All triangles degrees equal 180 so we can set up the problem the angle SPT(50) + the angle STP(50) + The angle PST(x) = 180 50+50=100 so it is 100+x=180 -100 PST(x)=80
