B

Answer:

B

Step-by-step explanation:

To know which line plot could represent the data, we take the sum of the miles covered by the runners and check if it adds up to 4 miles for each plot :

Plot 1 :

(1/12 * 1) + (1/8 * 2) + (1/6 * 1) + (1/4 * 2) + (1/3 * 1) + (1/2 * 3) = 2.8333

Plot 2 :

(1/6 * 2) + (1/4 * 2) + (1/3 * 2) + (1/2 * 3) + 1 = 3 +1 = 4 miles

Since the sum of the miles ran by the runners equals 4 miles for the second plot, hence, the second plot could represent the data for the runners.

Answer:

33.1

Step-by-step explanation:

First you need to find the area of the circle. The radius is 10 which means that the area is 314. Since a circle has 360 degrees, and the shaded area is 38 degrees, you need to divide 314 by 360 which is 0.87. Then multiply by 38 because the shaded sector is 38. 0.87 x 38 = 33.1.

That is the answer.

Answer:

Step-by-step explanation:

Let older brother age be x and the age difference between the brothers be y

Younger brother's current age = x - y

When older brother's age was at x - y, younger brother's age was x - 2y = 2

When young brother's age will be at x, older brother's age will be x + y = 20

Subtracting the first equation from the second: 3y = 18

y = 6

x = 14

So the older brother is 14 and the younger brother is 8.

Sum of three son's ages now = 15 + 11 + 7 = 33

Daddy's age now = 45

Age difference = 12

Each year, daddy's age goes up by 1 while the sum of three son's ages goes up by 3.

Dividing the age difference by the difference in age gain, 12 / (3 -1) = 12 / 2

= 6

So in 6  years when daddy is 51 and the sum of sons at 21, 17 and 13 will be equal.

Answer:

Step-by-step explanation:

older bro age is x

younger bro age is y

age diff = x - y

it was (x-y) years ago when older bro was at age y

younger bro age then was y - (x - y) =2

2y - x = 2

younger bro will be at age x in (x-y) years

older bro age then will be x + (x-y) = 20

2x - y = 20

4x - 2y = 40

adding 2y - x = 2

3x = 42

x = 14

y = 2*14 - 20 = 8

daddy' age, 45 is 12 over the sum of sons (15, 11 and 7)

in 1 yr, dad age +1 n sum of sons +3 = difference of 2

so in 12/2 = 6 yrs they will be the same

Answer:

20 Hours = 45 Houses

27 = 12 Hours

Step-by-step explanation:

The time taken to wash 45 houses is 20 hours and the number of houses in 12 hours is 27.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Stuart owns a window-washing business. He can wash the windows on 9 houses in 4 hours.

The time taken to wash 45 houses is,

9 houses = 4 hours

1 house = 4 / 9 hours

45 houses = ( 45 x 4 ) / 9 hours

45 houses = 20 hours

The number of houses in 12 hours,

4 hours = 9 houses

1 hour = 9 / 4 houses

12 hours = ( 9 x 12 ) / 4 houses

12 hours = 27 houses

Therefore, the time taken to wash 45 houses is 20 hours and the number of houses in 12 hours is 27.

Answer:

SAS

Step-by-step explanation:

the two triangles have two congruent sides and one congruent angle

The two given triangles are congruent by the side angle side (SAS) property. The correct option is D.

The Side-Angle-Side Congruence Theorem (SAS) defines two triangles to be congruent to each other if the included angle and two sides of one is congruent to the included angle and corresponding two sides of the other triangle.

An included angle is found between two sides that are under consideration.

In the given figure demonstrates two triangles that are congruent by the SAS Congruence Theorem.

Two triangles having two pairs of corresponding sides and one pair of corresponding angles that are congruent to each other is not enough justification for proving that the two triangles are congruent based on the SAS Congruence Theorem.

Therefore, the two given triangles are congruent by the side angle side (SAS) property. The correct option is D.

Formula for Surface Area of cube :

6  x  [tex]a^{2}[/tex]

In our case, the edges are 8, meaning would we would subsuite a with 8 in the equation. We would do 6 x 64, since [tex]8^{2}[/tex] is 64. 6 x 64 is 384, hence our answer is 384.

The Surface Area of the cube is 384 unit².

Surface area is the amount of space covering the outside of a three-dimensional shape.

Given: the edge of the cube, l= 8 units

Surface area of the cube =  6*l²

                                           = 6*8*8

                                           = 6*64

                                          = 384 unit²

Step-by-step explanation:

Triangle FCD is cut from parallelogram ABCD moved with left-hand side. What are the dimensions of the resulting rectangle AEFD?

A parallelogram is a quadrilateral (has four sides and four angles) in which opposite sides are parallel to each other.

A rectangle is a quadrilateral with opposite sides which are parallel and equal to each other. All the angles in a rectangle are at 90 degrees.

From the image, AD = z, FC = x, BF = w and BC = y. Hence:

EB = FC = x.

EF = AD = length = z; AE = FD = height = w

Therefore the dimensions of rectangle AEFD is length z and height w

Answer:

Every integer greater than 1 is either prime or composite.

Step-by-step explanation:

Let us negate this statement.

Assumption - any number greater than 1, is neither prime nor composite.

A prime number has only 2 divisors, and a composite number has at least 3.

Let a number be X such that X >1.

Now X is divisible by 1 (Any integer is divisible by 1)

And X is divisible by X (X/X = 1, if X is not zero)

So by this, we see X has at least 2 divisors, X is either prime, or composite if it has more divisors!

So our assumption is wrong, and every integer greater than 1 is either prime or composite.
