Answer: BXC =70°

Step-by-step explanation:

XBC= isosceles so XBC=XCB

XBC=55° (isosceles triangle)

BXC+XBC+XCB=180° (angles in a triangle =180°)

BXC=180°- (55°+55°)

BXC=180°-110°

BXC=70°

The probability of answering correctly if you make a random guess is:

P = 1/5 = 0.2

If you make a random guess, then you have no idea of which could (or couldn't) be the correct answer. Thus, all the 5 options have the exact same probability of being the correct one.

From this, the probability of answering correctly the question is given by the quotient between the number of correct answers (we assume is only one) and the total number of options (5).

So the probability is:

P = 1/5 = 0.2

Answer: 4

The ratio in which the chocolates are divided into types can be seen as splitting the chocolates into 1+2+2 = 5 equal parts. Since there are 20 chocolates, each part corresponds to 20/5 = 4 chocolates. Thus, there are 1*4=4 chocolates with nuts, 2*4=8 plain chocolates, and 2*4=8 chocolates with caramel. Now, the three boys are dividing the chocolates into 3+1+1 = 5 equal parts. Thus, each part again corresponds to 4 chocolates. So, Andy will receive 3*4=12 chocolates, Bert will receive 1*4=4 chocolates, and Charles will receive 1*4=4 chocolates. Because neither Andy nor Charles can eat nuts, and there are four chocolates with nuts, and Bert receives four chocolates, Bert must take all of the chocolates with nuts. Charles receives four chocolates total, and, since he prefers caramel, he will take four of the eight caramels. This leaves eight plain chocolates and four caramels to make up Andy's twelve chocolates. Thus, Andy receives 4 pieces of chocolate with caramel.

Answer:

Area = A = 65.999999999997 cm

Step-by-step explanation:

Circumference = 66 cm

Circumference = 2πr

So        2πr = 66 cm

     r = 66/2π =10.509554140127

Area of circle  = πr²   = 3.14(10.509554140127)²

Area = A = 65.999999999997

Answer:

x = 68

Step-by-step explanation:

The formula for calculating the sum of interior angles of a polygon is: (n - 2) x 180° (where n is the number of sides)

This polygon has 5 sides, so the sum of the interior angles:

(5 - 2) x 180° = 540°

To find x, add together all the angle expressions, equate to 540 and solve for x:

                                                       U + V + W + Y + Z = 540

                       (x - 8) + (3x - 11) + (x + 8) + x + (2x + 7) = 540

Gather like terms:  x + 3x + x + x + 2x - 8 - 11 + 8 + 7 = 540

Combine like terms:                                           8x -4 = 540

Add 4 to both sides:                                               8x = 544

Divide both sides by 8:                                             x = 68

Answer:

a) negative

b) -7/6

Step-by-step explanation:

The x value increased, but the y value decreased so the line goes down and has a negative slope

(y₁-y₂)/(x₁-x₂) is the slope where (x₁,y₁) and (x₂,y₂) are points on the line

Answer: 1.19

Step-by-step explanation: To convert this mixed number (fraction) to a decimal just follow these two steps:

Step 1: divide numerator (19) by the denominator (100): 19 ÷ 100 = 0.19

Step 2: add this value to the the integer part: 1 + 0.19 = 1.19. So,

1 19/100 = 1.19

Rounded values:

1 19/100 = 1 rounded to 0 decimal places

1 19/100 = 1.2 rounded to 1 decimal place1

I don't know how to show my answer on a computer.

Answer:

It has 15 sides.

Step-by-step explanation:

( n-2 ) × 180 / n = 156

180n - 360 = 156n .

180n - 156n = 360

24 n = 360

n = 360/24 = 180/12 = 90/6 = 15 .

n = 15 sides.

Answer:

the number is three

Step-by-step explanation:

6÷2 is equal to 3, so you do 3x5 which is equal to 15.

The value of sinD, sin E and cos D are 4/5, 3/5 and 3/5 respectively

According to SOH CAH TOA identity;

From the figure

Hypotenuse = 15

For sinm<D

sin D = EF/DE
sin D = 12/15

sinD = 4/5

For the trig function sin E

sin E = FD/DE
Sin E = 9/15

sinE = 3/5

For the trig function cos D:

cos D = FD/DE
cos D = 9/15

cos D = 3/5

Hence the value of sinD, sin E and cos D are 4/5, 3/5 and 3/5 respectively
