Answer:

DE=18

Step-by-step explanation:

The reason is because that parallelogram ABCD has most of the sides equal to each other.

The length of DB = 36 and half of 36/2 gets us DE.

DE=36/2=18

DE=18 also equals to BE=18

Diagonals of a parallelogram bisect each other

So

Putting DE=BE

The equation n = 30/t is an illustration of an inverse variation

The points on the graph are: (1,30), (2,15), (3,10) and (4,7.5)

The equation is given as:

n = 30/t

When t = 1, we have:

n = 30/1

n = 30

When t = 2, we have:

n = 30/2

n = 15

When t = 3, we have:

n = 30/3

n = 10

When t = 4, we have:

n = 30/4

n = 7.5

So the points on the graph are:

(1,30), (2,15), (3,10) and (4,7.5)

Answer:

  a)  1.6×10⁻⁶

  b)  2×10⁷

Step-by-step explanation:

You want the product or quotient in standard form of ...

The rules of exponents apply:

  (a^b)(a^c) = a^(b+c)

  (a^b)/(a^c) = a^(b-c)

A number is said to be in scientific notation if there is one digit to the left of the decimal point, and the multiplier is expressed to an appropriate power of 10. The power of 10 may need to be adjusted so the decimal point is in the correct place. In general, the power of 10 represents the place value of that most-significant digit.

In the US, a number is written in standard form as a sequence of digits with an optional decimal point. Integers are written so the least-significant digit has a place-value of 1.

Elsewhere, a number is written in standard form when it is written in scientific notation.

We have given both forms a number here, so you will need to choose the one that is standard form where you are.

The product is (8×2)×10^(-3-4) = 16×10^-7 = 1.6×10^-6

= 0.0000016

The quotient is (6/3)×10^(2-(-5)) = 2×10^7

= 20,000,000

The constant of variation given that  r varies directly with p and inversely with the product of s and t is one-half

r ∝ p ∝ 1/st

r ∝ p / st

r = Kp / st

Cross multiply

r × st = Kp

Divide both side by p

K = rst / p => constant of variation

K = rst / p

K = (18 × 1/6 × 2) / 12

K = 6 / 12

K = 1 / 2 = one-half

Answer:

The value of a side = 5

Step-by-step explanation:

By using PGT theoram

H² = P² + B²

=> 13² = a² + 12²

=> 13² - 12² = a²

=> 169 -144 = a²

=> 25 = a²

=> √25 = a

=> 5 = a

Answer:

a = 5

Step-by-step explanation:

using Pythagoras' identity in the right triangle.

the square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

a² + 12² = 13²

a² + 144 = 169 ( subtract 144 from both sides )

a² = 25 ( take square root of both sides )

a = [tex]\sqrt{25}[/tex] = 5

Answer:

Jeremy is 12 years old

Step-by-step explanation:

Jeremy age=X

Sister age=Y

1. X+Y=29 (sum of their ages)

2. X=Y-5 (he is 5 years younger than his sister)

*Substitute eq 2 into eq 1

Y-5+Y=29

2Y=29+5

2Y=36 (divide both sides by 2)

Y =17

Substitute value of Y into eq 1 to find X

X+17=29

X=29-17

X= 12

Checking answer:

12+17=29

17-5=12

Hence why Jeremy is 12

Answer:

y= 1/5 x -1

Step-by-step explanation:

Find two points ( any two of the three given)

find the slope between   5,0   and   10, 1

    ( 1-0)/(10-5)   = m = slope   = 1/5

so the line is of the form   y = mx + b :

                                            y = 1/5 x + b     sub in any point to calculate 'b'

                                             1 = 1/5 (10) + b

                                                    b = -1

y = 1/5 x -1   is your answer

Answer:

Surface Area = 96

Step-by-step explanation:

Area of Triangle: Area = 1/2 * Base * Height

Area = 1/2 * 6 * 2 = 6

Area = 6

Area of Rectange: Area = Length * Height

Area = 7 * 3 = 21

Area = 7 * 6 = 42

Area = 21

Surface Area = TopTri + BotTri + LeftRect + MidRect + RightRect

Surface Area = 6 + 6 + 21 + 42 + 21 = 96

The probability of getting less than 40% of employees wearing khaki pants in a random sample of 50 employees is 0.18.

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

P(E) = Number of favorable outcomes / total number of outcomes

In a large company, 45% of the employees wear khaki pants on a daily basis.

40% of employees wearing khaki pants in a random sample of 50 employees

So, 40% of 45% x 50

Answer:

y-intercept= (0,7) and rate of change=

Step-by-step explanation:

The y-intercept of a graph is the point on the graph where it intersects the y-axis or where x=0. In this case it is (0,7) so that is the y-intercept. The rate of change is equal to y2-y1 divided by x2-x1. Basically, just pick 2 random points on the line and subtract their y coordinates, then subtract their x-coordinates and divide the answers with each other. So, one point is (0,7) and another point is (2,4). Therefore, rate of change is 7-4 divided by 0-2. This gives us a rate of change of -3/2

Answer:

Step-by-step explanation:

The graph that represents the function

f(x) = (x + 4)(x + 1)(x - 3)

crosses the x-axis three times: at x = -4, x = -1, and x = 3

because we apply the zero product rule and found the roots -4, -1, and 3

x+ 4= 0 → x = -4

x+1 = 0 → x = -1

x-3 = 0 → x = 3

Hi!

The area of the entire figure is 76 units squared.

NOTE: This question has two different shapes: a rectangle, and a triangle.

Rectangle Formula:

Length * Width = Area

[tex]LW=A[/tex]

Triangle Formula

(Base * Height) / 2 = Area

[tex]\cfrac{bh}{2}=A[/tex]

Let's first get the rectangle's area:

[tex]LW=A[/tex]

[tex]8*7=A[/tex]

[tex]56=A[/tex]

The area of the rectangle is 56.

Now, for the top triangle:

[tex]\cfrac{bh}{2} =A[/tex]

[tex]\cfrac{8*2}{2} =A[/tex]

[tex]8=A[/tex]

The area of the top triangle is 8.

Now, for the bottom triangle.

[tex]\cfrac{bh}{2} =A[/tex]

[tex]\cfrac{8*3}{2} =A[/tex]

[tex]12=A[/tex]

The area of the bottom triangle is 12.

Now, add them all together:

[tex]56+8+12=76[/tex]

The shape ABCDE is a regular pentagon with five sides, such that the five sides are congruent

The angle BAE is a vertex angle, and it is calculated using:

BAE = 180 * (n - 2)/n

Where n= 5; i.e. the number of sides.

This gives:

BAE = 180 * (5 - 2)/5

Evaluate

BAE = 108°

Hence, the measure of angle BAE is 108°

When the vertices A and B are joined together, the shape becomes a trapezoid.

Hence, the name of the quadrilateral ABCD is a trapezoid.

See attachment for the new figure.

From the attached figure, we have:

∠EDX + ∠EDC = 180° ---- the sum of angles on a straight line

Where:

∠EDC = ∠BAE = 108°

So, we have:

∠EDX + 108° = 180°

Subtract 108° from both sides

∠EDX = 72°

Hence, the measure of angle EDX is 72 degrees

The quadrilateral BDXE is a parallelogram.
