Step-by-step explanation:

Area of the square:

a^2: 4^2=16in^2

Area of the circle:

πr^2: π(4.5)^2= 63.6

Area of white part:

63.6 - 16 = 47.6

Probability of landing on square:

16/63.6 = 0.25

Probability of landing on white part:

63.6/16 = 3.975

Answer:

f(-4) = -8

Step-by-step explanation:

f (x) = 2x

Let x=-4

f(-4) =2*-4

      = -8

Answer:

The answer is -8.

Step-by-step explanation:

f(x)=2x

f(-4)=2(-4)

f(-4)=-8.

Answer:

x = 16°

Step-by-step explanation:

We can see that AB is a straight line. The sum of angles on a straight line adds up to 180°

∠ACD + ∠DCE + ∠ECD = 180° (sum of angles on a straight line)

∠ACD = x, ∠DCE = 148,  ∠ECD = x

substituting the respected values for the angles gives:

x + 148 + x = 180

2x + 148 = 180

subtracting 148 from both sides:

2x + 148 - 148 = 180 - 148

2x = 32

Dividing both sides by 2, to get x:

2x/2 = 32/2

x = 16°

Answer:

8

Step-by-step explanation:

You can solve this by creating a linear equation.

Slope: 2.50

Y-intercept: 4.70

y=2.50x+4.70

Since we know that the total fare was 24.70 we can plug it into the y.

24.70=2.50x+4.70

Now solve for the equation.

20=2.50x

8=x

So he went 8 miles with the taxi.

Total number or mile taxi run is 8 miles.

Given that;

Pick up charge = $4.7

Charges per mile = $2.5 per mile

Total fare = $24.7

Find:

Number of mile taxi ride

Computation:

Total fare = Pick up charge + [Total number or mile taxi run][Charges per mile]

24.7 = 4.7 + [Total number or mile taxi run][2.5]

[Total number or mile taxi run][2.5] = 24.7 - 4.7

[Total number or mile taxi run][2.5] = 20

Total number or mile taxi run = 20 / 2.5

Total number or mile taxi run = 8 miles

Answer:

b^8

Step-by-step explanation:

Answer:

b^8, with m = 8

Step-by-step explanation:

Apply the algebraic rule: (x^a)/(x^b) = x^(a-b)

Note: This rule is true because we can cancel all b factors that occur in both numerator and denominator.

From this rule, we know that (b^10)/(b^2) = b^(10-2)

b^(10-2) can be written b^8

Set of events " rolling a six-sided cube and drawing 6 marbles out of a bag " have an equally like chance of occurring.

Option B is correct.

Probability of series of experiments shown below;

A. When spinning a spinner with 3 sections then probability of one section is [tex]\frac{1}{3}[/tex] .

 When tossing a coin, then probability of getting head or tail is [tex]\frac{1}{2}[/tex]

So that, set A has not equally like chance of occurring.

B. When rolling six-sided cube, probability of getting one number is [tex]\frac{1}{6}[/tex]

   When one marble is drawn out of 6 marble in a bag, then  probability is [tex]\frac{1}{6}[/tex]

Therefore, set B has equally like chance of occurring.

Answer:

Step-by-step explanation:

Step-by-step explanation:

13.

Supplementary angles = 180º (theorem)

Set <ABD + <DBC = 180º

2x + (x+24) = 180º

add like terms = 3x+24=180

3x=156

x = 52

now plug in x for both angles

<ABD = 2(52) = 104

<DBC = 52+24 = 76

14.

complementary angles = 90º (theorem)

set <EFG + <GFH = 90º

y-32 + y = 90

2y - 32 = 90 : combine like terms

2y = 122

y = 61

now plug in y for both angles

<EFG = 61-32 = 29

<GFH = 61

15.

Vertical angles are equal to each other (theorem)

<PQR = <TRS

38 = 5w-7

45 = 5w

w = 9

plug into <TRS

<TRS = 5(9) - 7 = 38

(Also since you know that <PRQ is 38 and that the measure has to be the same for both angles, it can be assumed without algebra that <TRS would be 38º)

The radius of the circle is 17 feet. Then the area of the circle is 907.46 square feet.

It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.

Let r be the radius of the circle. Then the area of the circle will be given as,

A = πr² square units

The diameter of the circle is 34 feet. Then the radius of the circle is calculated as,

r = 34 / 2

d = 17 feet

The area of the circle is calculated as,

A = πr²

A = 3.14 x 17 x 17

A = 907.46 square feet

Answer:

Step-by-step explanation:

200 of 10 was 5 percent

Answer:

£ 105.

Step-by-step explanation:

Since it is required to decrease £ 120 by 12.5%, to perform this subtraction the following mathematical operation must be performed:

100 - 12.5 = 87.5

100 = 120

87.5 = X

87.5 x 120/100 = X

10,500 / 100 = X

105 = X

Thus, decreasing £ 120 by 12.5% you get a total of £ 105.

The answer is B. 35 mph

Speed is shown as distance/time

If you pick a point, for example 70 miles and divide it by the time which is 2 hours, then you get 35 miles per hour
