Find the measure of arc CB

Answers

Answer:

Arc CB is equals to 160

Step-by-step explanation:

Add all of those numbers and subtracted by 360

Answer:

Step-by-step explanation:

Remark

Be very careful that you understand which arc you are asking for. Arc CB could be the arc made up of 53 + 79 + 68 = 200.

Somehow I get the idea that is not what you want. You want the arc that is not divided up so it is

Arc CB = 360 - Sum of the minor arcs

Arc CB = 360 --  200

Arc CB = 160

A 300$ mountain bike is discounted by 30%, and there is a 8% sales tax. Find the final cost of the mountain

Answers

Answer:

[see below]

Step-by-step explanation:

The bike's original price is 300 dollars. It has been discounted by 30%.

300 * 0.3 = 90

The price would be 90 dollars off.

300 - 90 = 210

$210 would be the subtotal.

There is also an 8% sales tax.

210 * 0.08 = 16.80

210 + 16.80 = 226.80

Hope this helps you!

Answer:

cost of the bike =$300

discount = 30%

Price of the bike ={ (30/100)×300}-300=210

Sales tax= 8%

Final cost =( 8/100)×210=16.80+210=226.80

[tex]x^2-x-6=0[/tex]

Answers

Answer:

x = - 2, x = 3

Step-by-step explanation:

Given

x² - x - 6 = 0

Consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term (- 1)

The factors are + 2 and - 3 , since

2 × - 3 = - 6 and 2 - 3 = - 1 , then

(x + 2)(x - 3) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 3 = 0 ⇒ x = 3

Answer:

[tex]x^2-x-6=0[/tex]

[tex]\left(x+2\right)\left(x-3\right)=0[/tex][tex]x+2=0\quad \mathrm{or}\quad \:x-3=0[/tex][tex]x+2=0[/tex][tex]x+2-2=0-2[/tex]     ← Subtract 2 from both sides[tex]x=-2[/tex][tex]x-3=0[/tex][tex]x-3+3=0+3[/tex]    ← add 3 to both sides[tex]x=3[/tex]

Find the area of each figure. Use 3.14

Answers

Answer:  23.13 square meters

===============================================================

Explanation:

The top and bottom semicircles can be joined to form a full circle. The same can be said about the left and right semicircles. Each circle has diameter 3 and radius 1.5

The area of one circle is

A = pi*r^2

A = 3.14*(1.5)^2

A = 7.065

So two circles doubles to 2*7.065 = 14.13 square meters in area.

Then the last step is to add on the area of the 3 by 3 square (area 3*3 = 9) to get 14.13+9 = 23.13

This area is approximate because pi = 3.14 is approximate. Use more decimal digits in pi to get a more accurate area. However, your teacher wants you to use this specific value so it's best to stick with 23.13

Answer:

23.14

Step-by-step explanation:

The shape is basically two equal-sized circles and a square.

Find the area of the square: 3 x 3 = 9

9 is the area of the square

The formula for finding the area of a circle is pi x radius squared.

3.14 x 1.5 squared = 7.06858

Round to 7.07 and multiply by 2 = 14.14

14.14 (area of both circles) + 9 (area of square) = 23.14

Step-by-step explanation:

6x+1 = 9x-23

add 23 to both sides

subtract 6x from both sides

3x=24

x=8

Answer:

8 =x

Step-by-step explanation:

The angles are the same so

6x+1 = 9x-23

Subtract 6x from each side

6x+1-6x = 9x-6x-23

1 = 3x-23

Add 23 to each side

1 +23 = 3x-23+23

24 = 3x

Divide by 3

24/3 = 3x/3

A triangle and a rectangle are shown below.

The area of the rectangle is 5 times the area of the triangle.

Work out the width(w) of the rectangle

Answers

Answer:

10 cm

Step-by-step explanation:

From the diagram,

Applying,

lw = 5/2(bh)..................... Equation 1

Where l = length of the rectangle, w = width of the rectangle, b = base of the triangle, h = height of the triangle.

make w the subject of the equation

w = 5(bh)/2l............... Equation 2

From the diagram,

Given: l = 12 cm, b = 6 cm, h = 8 cm

Substitute into equation 2

w = 5(6×8)/(2×12)

w = 10 cm

Hence the width of the rectangle is 10 cm

The points (30, 50). (-10, 30) and (-20, s) all lie on the same line. What is the value of s? Show your work.

Answers

Answer:

s = 25

Step-by-step explanation:

First we go from point (30, 50) to point (-10, 30).

Change in x: -10 - 30 = -40

Change in y: 30 - 50 = -20

Since a change in x of -40 results in a change in y of -20, we divide both changes by 4 to get:

a change of -10 in x results in a change of -5 in y.

Now we go from point (-10, 30) to point (-20, s).

The change in x is -20 - (-10) = -10

The corresponding chang ein y must be -5.

y = 30 - 5 = 25

Answer: s = 25
