Find the measure of the missing angle.
a
20°

Answer:

Arc length = 54.85mm

Step-by-step explanation:

360/32 = 11.25

11.25 * 559 = 6288.75

6288.75 * 3.14 = 19746.675

19746.675/ 360 = 54.851875

Rounded to the nearest hundredth

Arc length = 54.85mm

The length of the arc is 54.9mm

Data given;

To solve this question, we have to use the formula of length of an arc which is given as

L = θ/360 * 2πr

To find the angle between each spoke, let's divide 360 by 32

[tex]\theta = 360/32\\\theta = 11.25^0[/tex]

Now that we have the value of the angle, let's substitute it and solve for the length of the arc.

[tex]L_a_r_c = \theta/360 * 2\pi r\\L_a_r_c = \frac{11.25}{360} * 2 * 3.14 * 279.5\\L_a_r_c = 54.9mm[/tex]

The length of the arc is approximately 54.9mm

Answer:

2.75

Step-by-step explanation:

absolute value means it is always positive so in this case it stays the same

Answer:

2.75

Step-by-step explanation:

The absolute value of any number is it's positive variant. For example, the absolute value of -100 is 100. The absolute value of 100 is also 100.

Thus, the absolute value of 2.75 is simply 2.75

Answer:

£10

Step-by-step explanation:

With these 'sharing' ratio questions, first work out the total amount of parts in the ratio:

1:3:5 = 1 + 3 + 5 = 9 parts

Now divide the total amount of parts by the total amount of money shared :

90 / 9 = 10

Now multiply by the appropriate value, in this case, aahil.

aahils value is 1.

1 × 10 = £10

Answer:

The fourth answer, WBD is correct.

Step-by-step explanation:

As you can see the three points W, B and D all fall on the same line, which means that they are indeed colinear.

Answer:

W, B and D all fall on the same line, which means that they are indeed colinear.

Step-by-step explanation:

Answer:

y ≤ x - 1

Step-by-step explanation:

from 2 points (0, -1) and (1, 0) we can find the slope = 1 and the y-intercept = -1

therefore, the slope-intercept form of this line is:  y = x - 1

since it's an inequality, we replace the equal sign with an inequality symbol

we choose '≤' because the line is solid (as opposed to dashed) and all points in the shaded area are less than when plugged into the equation

y ≤ x - 1

Check:

select a point in the shaded region, example (2, 0)

2 is the x-value and 0 is the y-value

plug in to see if the inequality is true:  0 ≤ 2 - 1  True

Answer:

AB=12 this is the diameter radius would be 6 unit  

Step-by-step explanation:

The length of the radius of the circle is 1.909.

The circumference of a circle is the length of the boundary of the circle. If we cut open the circle and straighten it the length of the boundary will be the measure of the circumference of the circle.

The circumference of a circle is measured in units of length like meter, centimeter, etc. The formula for calculation of circumference is,

Circumference = 2πR

Where R is the radius of the circle,

π (pi) is a constant value.

The value of π = 3.1415926535897.

According to the question

Clearly the arc ACB is the half the circumference of the circle

⇒ [tex]\frac{1}{2} 2\pi r=6[/tex]

⇒ [tex]r = \frac{6}{\pi }[/tex]

⇒ r = 1.909

Hence, the length of the radius of the circle is 1.909.

Answer:

81 pencils

Step-by-step explanation:

1. Set up variables

Pencils = p

notebooks= n

2. Set up a system of equations

p+n= 135                             (The amount of supplies bought)

1.75n +0.35p = 122.85       (Equation for the cost)

3. Solve the system of equations (I'll use substitution)

    a)p= 135-n  (I just rearranged it)

    1.75n + 0.35p= 122.85

     b) Substitute the first equation into the second)

    1.75n + 0.35(135-n) = 122.85

     c) Solve!

    1.75n + 47.25 - 0.35n = 122.85

    1.4n = 75.6

     n= 54

Serena bought 54 notebooks!

4. Substitute the number of notebooks into the first equation

p +n = 135

p + 54= 135

p = 81

Serena bought 81 pencils!!!

I hope this helps!!!!

Answer:

Serena purchased 81 pencils

Step-by-step explanation:

Let x = the number of pencils Serena bought

Let 135 - x = the number of notebooks Serena bought

1.75(135 - x) + .35x = 122.85       Multiply both sides of this equation by 100.

175(135 - x) + 35x = 12,285

23,625 - 175x  + 35x = 12,285

-140x = -11,340

x = 81 pencils
