I need help on this problem! <br><br> g(h+2/3)=1 for h
Tju [1.3M]

Answer:

g(h +  \frac{2}{3} ) = 1 \\  \\ gh +  \frac{2}{3} g = 1 \\  \\ gh = 1 -  \frac{2}{3} g \\  \\  h = (1 -  \frac{2}{3} g )  \div g \\  \\ h = (1 -  \frac{2}{3} g ) \times   \frac{1}{g}  \\  \\ h =  \frac{1}{g}  -  \frac{2}{3}

A pair of $195 boots are discounted 40% If the boots are reduced in price by an additional 66 2/3% what will the discount price
UNO [17]
First, find the 40% discount.
40% of 195 is 78
195 x 0.40 = 78
Subtract that from 195
195 - 78 = 117
Now, find 66 2/3% of 117, since it is an additional reduction after the original discount.
2/3 = 0.667, so 66 2/3% is 66.667%
117 x 0.66667 = 78.00039
And subtract that from 117
117 - 78.00039 = 38.99961, which in dollars would be $38.99. (hundredths, etc. of a cent are usually just dropped; no rounding involved.)
The discount price would then be $38.99

Someone plz help!!!!!! ​
aliina [53]

Answer: X = 7√2

Step-by-step explanation:

Let first Consider triangle BDC,

Cos C = adjacent/ hypothenus

Cos C = 7 / x ...... (1)

Also, let consider triangle ABC

Cos C = adjacent / hypothenus

Cos C = x / 14 ....... (2)

Since angle C is the same, equate equation 1 to 2

7/ x = x / 14

Cross multiply

X^2 = 98

Make x the subject of formula

X = sqrt (98)

X = sqrt ( 49 × 2 )

X = sqrt (49) × sqrt (2)

X = 7 sqrt(2)

X = 7√2
