Answer:
D. 1.5
Step-by-step explanation:
One basic property you need to keep in mind while solving theses type of questions is as follows :
<u>The length of tangents from an external point on a circle are equal</u>. For simplicity a figure illustrating this property is attached.
- Length of RS = 6 ; Length of AS = RS - AR = 6-x
Consider S as external point and tangents as SA and SB, so SB=SA=6-x
- Length of ST = 9 ; Length of TB = ST - SB = 9 - (6-x) = 3+x
Consider T as external point and tangents as TB and TC, so TC=TB=3+x
- Length of TU = 7 ; Length of UC = TU - TC = 7 - (3+x) = 4-x
Consider U as external point and tangents as UC and UD, so UD=UC=4-x
- Length of UV = 15 ; Length of VD = UV - UD = 15 - (4-x) = 11+x
Consider V as external point and tangents as VD and VE, so VE=VD=11+x
- Length of VR = 14 ; Length of RE = VR - VE = 14 - (11+x) = 3-x
Now, Consider R as external point and tangents as RA and RE, so
RA = RE
x = 3 - x
2x = 3
x = ![\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D)
x = 1.5
Answer:
80 / 89
Step-by-step explanation:
Please see attached photo for explanation.
In the attached photo, the following data were obtained:
<I = θ
Hypothenus = 89
Opposite = 80
Sine <I =?
Sine ratio of <I can be obtained as follow:
Sine θ = Opposite / Hypothenus
Sine <I = 80 / 89
Thus, the ratio of sine <I is 80 / 89
Answer:
8 Liters
Step-by-step explanation:
Percentage of Alcohol in water= 2L X 0 =0
Percentage of Alcohol to be added = xL X 0.9 =0.9x
- New Volume =(x+2) Liters
- Desired Concentration = 0.72%
Therefore:
0+0.9x=0.72(x+2)
0.9x=0.72x+1.44
Collect like terms
0.9x-0.72x=1.44
0.18x=1.44
Divide both sides by 1.44
x=8 Liters
Therefore, Shanice must add 8 Liters of 90% alcohol solution to create the desired mixture
