PÕQ = 40°? [WAEC] A pie chart is divided into four sectors as shown in Fig. 12.46. Each sector represents a percentage of the wh
Serhud [2]

Answer:

126°

Step-by-step explanation:

the total max percent can be 100%

OR

The total value of the pie is 100%

that means all sectors must add upto 100

=> x + x + 21 + 9 = 100

=> 2x + 30 = 100

=> 2x = 70

=> x = 35

therefore, the two large sectors which are both equal to x each represents 35% of the whole.

<u>Angle subtended by one of those large sectors</u> :-

\theta  =  \frac{component \: part}{total}  \times 360

=  \frac{35}{100}  \times 360 \\  = 126

therfore, the central angle of the big sector is<u> 126°</u>

Sara bought a new doll at a 20% off sale and saved $12. What was the regular price of the doll?
nordsb [41]

Answer:

regular price = $15

Step-by-step explanation:

Represent the regular price by d.  Then the discount was 0.20d, and the sale price was (1 - 0.20)d, or 0.80d, which is $12.

Solving for d, we divide both sides by 0.80:

d = regular price = $15

If f(x)f(x) is an exponential function where f(-0.5)=27f(−0.5)=27 and f(1.5)=21f(1.5)=21, then find the value of f(0.5)f(0.5), t
vovikov84 [41]

Given:

f(x) is an exponential function.

f(-0.5)=27

f(1.5)=21

To find:

The value of f(0.5), to the nearest hundredth.

Solution:

The general exponential function is

f(x)=ab^x

For, x=-0.5,

f(-0.5)=ab^{-0.5}

27=ab^{-0.5}          ...(i)

For, x=1.5,

f(1.5)=ab^{1.5}

21=ab^{1.5}          ...(ii)

Divide (ii) by (i).

\dfrac{21}{27}=\dfrac{ab^{1.5}}{ab^{-0.5}}

\dfrac{7}{9}=b^2

Taking square root on both sides, we get

\dfrac{\sqrt{7}}{3}=b

b\approx 0.882

Putting b=0.882 in (i), we get

27=a(0.882)^{-0.5}

27=a(1.0648)

\dfrac{27}{1.0648}=a

a\approx 25.357

Now, the required function is

f(x)=25.357(0.882)^x

Putting x=0.5, we get

f(0.5)=25.357(0.882)^{0.5}

f(0.5)=23.81399

f(0.5)\approx 23.81

Therefore, the value of f(0.5) is 23.81.
