Answer:

44 in

Step-by-step explanation:

The circumference of the tire will be the same as the distance the unicycle moves in one complete revolution.

Find the circumference with the formula C = [tex]\pi[/tex]d, where d is the diameter

Plug in the values:

C = [tex]\pi[/tex](14)

C = approx. 44 in

Answer:

Lower quartile - (20+32) divided by 2 = 26

Median - (43+46) divided by 2 = 44.5

Answer:

d ≈ 8.5

Step-by-step explanation:

Distance Formula: [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Simply plug in our 2 coordinates into the formula:

d = √[(5 + 3)² + (-2 - 1)²]

d = √[(8)² + (-3)²]

d = √(64 + 9)

d = √73

d = 8.544

d ≈ 8.5

Answer:

10

Step-by-step explanation:

2^0 = 1

5^1  = 5

4^3 = 4 x 4 x 4

=> 16 x 4

=> 64

=> 1 + 5 + 64 / 7

=> 6 + 64 / 7

=> 70 / 7

=> 10

So, the answer is 10

Answer:

The answer is 90 degrees

Step-by-step explanation:

Both A and B make a right angle, which is 90 degrees.

Hope it helped :)

The value of m∠A + m∠B is 90°

It is defined as the angles when two lines intersect each other and at the intersecting point, some pair of angles are formed which we call vertically opposite angles, as the name describes that they have vertically opposite angles.

Three lines intersect to form 5 angles such that:

From the top left ∠B made and after this 90° made.

∠D = 124°

From the figure, we can clearly see ∠A = ∠C (vertically opposite angles)

We can calculate ∠C = 360°-90°-90°-124° ⇒ 56°

Also ∠A = 56°

and ∠B = 90° - 56° ⇒ 34°

Now we can calculate the sum of the angle ∠A+∠B = 56+34 ⇒ 90°

Thus, the value of m∠A + m∠B is 90°

Answer:

0.6048

Step-by-step explanation:

Given the following :

Assume a normal distribution :

Mean (m) = 105

Standard deviation (sd) = 20

Find the probability that a randomly selected adult has an IQ between 88 and 122 .

Z = (x - m) / sd

For IQ score of 88:

Z = (88 - 105) / 20

Z = (-17) / 20

Z = - 0.85

For IQ score of 122:

Z = (122 - 105) / 20

Z = (17) / 20

Z = 0.85

P(-0.85<Z<0.85) = P(Z < 0.85) - P(Z < - 0.85)

P(-0.85<Z<0.85) = (0.8023 - 0.1977)

P(-0.85<Z<0.85) = 0.6048

[tex]60 \div 5 = 12[/tex]

[tex]8 \times 12 = 96km[/tex]

Answer:

96 kilometers

Step-by-step explanation:

Let's set up a proportion using the following setup.

scale / actual = scale / actual

The scale is 5 cm to 60 km.

5cm / 60 km= scale/ actual

The distance on the map is 8 cm, but the actual distance is unknown. Therefore, we can say the actual distance is x km.

5 cm/ 60 km= 8 cm/ x km

5/60=8/x

Cross multiply. Multiply the numerator of the first fraction by the denominator of the second. Then, multiply the denominator of the first by the numerator of the second.

(5*x)=(8*60)

5x=8*60

5x=480

5 and x are being multiplied. The inverse of multiplication is division. Divide both sides of the equation by 5.

5x/5=480/5

x=480/5

x=96

x= 96 km

The actual distance between the two points is 96 kilometers.

Answer:

12950

Step-by-step explanation:

comedy : 20% => 20 × 18500 ÷ 100 = 3700

drama : 23% => 23 × 18500 ÷ 100 = 4255

other : 27% => 27 × 18500 ÷ 100 = 4995

all together: (20 + 23 + 27) × 18500 ÷ 100 = 3700+4255+4995 = 12950

The solution is 12950.

A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

here, we have,

from the given graph, we get,

comedy : 20%

=> 20 × 18500 ÷ 100

= 3700

drama : 23%

=> 23 × 18500 ÷ 100

= 4255

other : 27%

=> 27 × 18500 ÷ 100

= 4995

so, we get,

all together: (20 + 23 + 27) × 18500 ÷ 100

                   = 3700+4255+4995

                   = 12950.

2 - [tex]\sqrt{3}[/tex]

Step-by-step explanation:

Using the addition formula for tangent

tan(A - B) = [tex]\frac{tanA-tanB}{1+tanAtanB}[/tex] and the exact values

tan45° = 1 , tan60° = [tex]\sqrt{3}[/tex] , then

tan15° = tan(60 - 45)°

tan(60 - 45)°

= [tex]\frac{tan60-tan45}{1+tan60tan45}[/tex]

= [tex]\frac{\sqrt{3}-1 }{1+\sqrt{3} }[/tex]

Rationalise the denominator by multiplying numerator/ denominator by the conjugate of the denominator.

The conjugate of 1 + [tex]\sqrt{3}[/tex] is 1 - [tex]\sqrt{3}[/tex]

= [tex]\frac{(\sqrt{3}-1)(1-\sqrt{3}) }{(1+\sqrt{3})(1-\sqrt{3}) }[/tex] ← expand numerator/denominator using FOIL

= [tex]\frac{\sqrt{3}-3-1+\sqrt{3} }{1-3}[/tex]

= [tex]\frac{-4+2\sqrt{3} }{-2}[/tex]

= [tex]\frac{-4}{-2}[/tex] + [tex]\frac{2\sqrt{3} }{-2}[/tex]

= 2 - [tex]\sqrt{3}[/tex]

Answer:

97.98

Step-by-step explanation:

The area of the parallelogram PQR is the magnitude of the cross product of any two adjacent sides. Using PQ and PS as the adjacent sides;

Area of the parallelogram = |PQ×PS|

PQ = Q-P and PS = S-P

Given P(0,0,0), Q(4,-5,3), R(4,-7,1), S(8,-12,4)

PQ = (4,-5,3) - (0,0,0)

PQ = (4,-5,3)

Also, PS = S-P

PS = (8,-12,4)-(0,0,0)

PS = (8,-12,4)

Taking the cross product of both vectors i.e PQ×PS

(4,5,-3)×(8,-12,4)

PQ×PS = (20-36)i - (16-(-24))j + (-48-40)k

PQ×PS = -16i - 40j -88k

|PQ×PS| = √(-16)²+(-40)²+(-88)²

|PQ×PS| = √256+1600+7744

|PQ×PS| = √9600

|PQ×PS| ≈ 97.98

Hence the area of the parallelogram is 97.98
