a windscreen wiper of a vehicle of length 30 cm clears out an angle of 180 degrees what is the area of the screen cleared take p
zavuch27 [327]

Answer:

Therefore the area of the screen cleared is 1414.28 cm².

Step-by-step explanation:

Given:

a windscreen wiper of a vehicle of length 30 cm

Consider this length as Radius of Semicircle, r = 30 cm

clears out an angle of 180 degrees implies Semicircle Shape

pie=22/7

To Find:

Area of the screen cleared ​

= ?

Solution:

We have

\textrm{Area of Semicircle}=\frac{1}{2}\pi(radius)^{2}

Substituting r and pie we get

\textrm{Area of Semicircle}=\frac{1}{2}\times \frac{22}{7}(30)^{2}=1414.28\ cm^{2}

Therefore the area of the screen cleared is 1414.28 cm².

Irina18 [472]

Answer:

0.66

Step-by-step explanation:

1.00 - 0.34 = 0.66

The probability of certainty is 100%=1

If Probability(p)=0.34

then

0.34+Probability=1

Probability(!p)=1−0.34=0.66

If a TV cost $3960.00 and toes on sale during the following week with a 25% discount, what will be the total cost of the TV? but
Free_Kalibri [48]

we have the price of TV is $3960.if we round off to the nearest tens we get same 3960 because we have 0 at the end which means lesser than 5 so 60 will be the nearest ten.

discount =\frac{25}{100} *3960=990

so $990 will be the discount.

and the cost of TV after discount is 3960-990=$2970

Find the missing coefficient.<br><br> -<br> y2 − [-5y − y(-7y − 9)] − [-y (15y + 4)] = 0
maria [59]
There is only one solution in the given equation -y2 − [-5y − y(-7y − 9)] − [-y (15y + 4)] = 0. In solving this problem, apply first PEMDAS (parenthesis, exponents,multiplication, division, addition, subtraction). Then equation will transform into -y2+5y-7y2-9y+15y2+4y=0. Combine terms with same power and achieve 7y2=0. Divide both sides with 7 and perform square root of zero. Since the root is zero, we have one solution of the given equation which is y=0.
