Answer:

{\huge{\pink{\underline{\underline{Solution:}}}}}

As we know,sum of angles on a straight line is 180 degree..

(5z-4)+90+39=180

=>5z-4+90+39=180

=>5z-4+129=180

=>5z+125=180

=>5z=180-125

=>z=55÷5

Hence,the value of z=11 degree

<u>Answer:</u>

Height of cables = 23.75 meters

<u>Step-by-step explanation:</u>

We are given that the road is suspended from twin towers whose cables are parabolic in shape.

For this situation, imagine a graph where the x-axis represent the road surface and the point (0,0) represents the point that is on the road surface midway between the two towers.

Then draw a parabola having vertex at (0,0) and curving upwards on either side of the vertex at a distance of x = 600 or x = -600, and y at 95.

We know that the equation of a parabola is in the form y=ax^2 and here it passes through the point (600, 95).

y=ax^2

95=a \times 600^2

a=\frac{95}{360000}

a=\frac{19}{72000}

So new equation for parabola would be y=\frac{19x^2}{72000}.

Now we have to find the height (y)of the cable when x= 300.

y=\frac{19 (300)^2}{72000}

y = 23.75 meters

Lemon goes to the store and buys a game station for $25. The store is running a discount of 15%. What is the price of the game s
TEA [102]

Answer:

$21.25

Step-by-step explanation:

1. Convert the 15% to a decimal by dividing by 100.     15 ÷ 100 = 0.15

2. Multiply the $25 by the decimal of 15%.                    25 × 0.15 = 3.75

3. Subtract your previous answer (3.75) from the original price of the game station.        25 - 3.75 = 21.75

4. Therefore the price of the game station after the discount is $21.75.
