1.08 seconds because if you use cross multiplication by putting 3 over 225 = x over 81, using cross multiplication is 3 times 81 and 225 times x. So then you have 3 times 81 is 243 then divide by 225 to get x and you get 1.08 secs
Answer: 1/3
Step-by-step explanation:
Answer:
3+5+4=12units3
Step-by-step explanation:
A prism has a length of 3 units, height of 5 units, and width of 4 units. 3 + 5 + 4 = 12 Units cubed 3(4) + 5 = 17 Units cubed.
Answer:
No its independent
Step-by-step explanation:
because you'll have to divide and stuff
Answer:
Area of ΔQRS = 2.3 square inches
Step-by-step explanation:
From the given information,
<S + <Q + <R = ![180^{o}](https://tex.z-dn.net/?f=180%5E%7Bo%7D)
51 + 44 + <R = ![180^{o}](https://tex.z-dn.net/?f=180%5E%7Bo%7D)
95 + <R = ![180^{o}](https://tex.z-dn.net/?f=180%5E%7Bo%7D)
<R =
- 95
= ![85^{o}](https://tex.z-dn.net/?f=85%5E%7Bo%7D)
<R = ![85^{o}](https://tex.z-dn.net/?f=85%5E%7Bo%7D)
Applying the Sine rule, we have;
=
= ![\frac{s}{SinS}](https://tex.z-dn.net/?f=%5Cfrac%7Bs%7D%7BSinS%7D)
Using
= ![\frac{s}{SinS}](https://tex.z-dn.net/?f=%5Cfrac%7Bs%7D%7BSinS%7D)
= ![\frac{2.3}{Sin51}](https://tex.z-dn.net/?f=%5Cfrac%7B2.3%7D%7BSin51%7D)
r = ![\frac{2.3*Sin85}{sin51}](https://tex.z-dn.net/?f=%5Cfrac%7B2.3%2ASin85%7D%7Bsin51%7D)
= 2.9483
r = 2.9 inches
Also,
= ![\frac{s}{SinS}](https://tex.z-dn.net/?f=%5Cfrac%7Bs%7D%7BSinS%7D)
= ![\frac{2.3}{Sin51}](https://tex.z-dn.net/?f=%5Cfrac%7B2.3%7D%7BSin51%7D)
q = ![\frac{2.3*Sin44}{Sin51}](https://tex.z-dn.net/?f=%5Cfrac%7B2.3%2ASin44%7D%7BSin51%7D)
= 2.0559
q = 2.0 inches
From Herons formula,
Area of a triangle = ![\sqrt{s(s-q)(s-r)(s-s)}](https://tex.z-dn.net/?f=%5Csqrt%7Bs%28s-q%29%28s-r%29%28s-s%29%7D)
s = ![\frac{2.3 + 2.0 + 2.9}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2.3%20%2B%202.0%20%2B%202.9%7D%7B2%7D)
= 3.6
Area of ΔQRS = ![\sqrt{3.6(3.6-2.0(3.6-2.9)(3.6-2.3)}](https://tex.z-dn.net/?f=%5Csqrt%7B3.6%283.6-2.0%283.6-2.9%29%283.6-2.3%29%7D)
= 2.2895
Area of ΔQRS = 2.3 square inches
