If K is the midpoint of ER, EK = z+5,and ER=4x+2,What is the length of K R?

Answers

Answer:

KR = 9

Step-by-step explanation:

If K is the midpoint of ER, then EK = KR and ER = 2(EK).

Given:

ER = 4x + 2EK = x + 5

         ER = 2(EK)

⇒ 4x + 2 = 2(x + 5)

⇒ 4x + 2 = 2x + 10

⇒ 2x + 2 = 10

⇒ 2x = 8

⇒ x = 4

As EK = KR  and EK = x + 5  and x = 4:

⇒ KR = 4 + 5    

KR = 9

EK+KR=EREK+EK=ER2(EK)=ER2(x+5)=4x+22x+10=4x+2-2x=-8x=4

KR:-

A gardener uses a triangular prism clay pot to plant flowers. The triangular base is 3 units along the base and 5 units high. The pot has a height of 16 units high. What is the volume of the pot.

Answers

to find:

the volume of the pot.

solution:

bolume of a triangular prism= BH

area of a triangle= 1 / 2 × base × height

B = 1 / 2 × b × h

b = 3 units

h = 5 units

B = 1 / 2  × 3 × 5

B = 15 / 2

B = 7.5 units²

H = 26 units

 B = 7.5 units²

V = 7.5 × 26

V= 195 unit³

so, the volume of the pot is 195 unit³.

Prices for bicycles are given below
The price of a red bike is the price of a blue bike is 2/3
The price of a green bike is 5/4
Since the price of a green bike is $210 more than the price of a blue bike, how much does a red bike cost?
A) $360 B) $440 C) $560 D)$720

Answers

Answer:

C) $560

Step-by-step explanation:

Suppose that: r=price of red bike ,  b=price of blue , g=price of green.

Given: r=(2/3)b   g=(5/4)b  g=210+b  

Solution:

(5/4)b=210+b                   (g=g)

(5/4)b-b=210                   (take b as common factor)

b((5/4)-1)=210                  

b(0.25)=210  

b=210/0.25=$840    (so the price of blue bike is 840$)

Substitute b in equation of r:

r=(2/3)b=(2/3)(840)=560

so red bike costs $560.

Using sampling concepts, it is found that a systematic sampling of 500 words would be achieved as follows:

B. Randomly select one of the first 200 words and then every 200th word thereafter for the sample.

How are samples classified?

Samples may be classified as:

Convenient: Drawn from a conveniently available pool.Random: All the options into a hat and drawn some of them.Systematic: Every kth element is taken. Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.Stratified: Also divides the population into groups. Then, a equal proportion of each group is surveyed.

In this problem, he wants a systematic sampling, hence he should choose every kth word, which means that the answer is between options a and b.

He will choose 500 words out of 100,000, hence the value of k is given by:

k = 100000/500 = 200.

Which means that option B is correct.

What is an equation of the the line that passes through the point (-1,4) and is parallel to the line x+y=4

This is so important!! Ive tried everything

Answers

Answer:

y = -x + 3

Step-by-step explanation:

the equation is parallel to the line

y + x = 4

y = 4 - x

parallel means the same slope. So our new equation has a slope of -1

Now, the equation of a line is given by y = mx + b where m is the slope.

y = -x + b

now we plug in the points given in the question to find b.

4 = 1 + b

b = 3

so the final answer is y = -x +3

make sure to comment if you need any further guidance.

Parallel lines have same slope. Write the given equation in y = mx + b form
x + y = 4
y = -x + 4
m = -1

Equation of the required line:
y= -1x + b
Now plug-in (-1,4) in the above equation
4 = -1 * (-1) + b
4 = 1 + b
4 -1 = b
b = 3
Equation:
y = -x + 3

Answers

Step-by-step explanation:

a geometric sequence means that every term is created by multiplying the previous term by a certain constant factor. this factor is called the "common ratio".

so,

6×r = 18

r = 18/6 = 3

and a quick check tells us this works also for the next terms (18×3 = 54, 54×3 = 162), so it is indeed a geometric sequence with common ratio 3.

a0 = 6

a1 = a0 × 3 = 6×3 = 18

a2 = a1 × 3 = a0 × 3×3 = 6×3² = 54

an = a0 × 3^n = 6 × 3^n

so,

f(x) = 6×3^x, x is integer, x >=0

Determine the coordinate of the point where
y=3x+6 crosses the x-axis.

Answers

Answer:

(- 2, 0 )

Step-by-step explanation:

to find where the line crosses the x- axis, let y = 0 in the equation and solve for x.

0 = 3x + 6 ( subtract 6 from both sides )

- 6 = 3x ( divide both sides by 3 )

- 2 = x

the line crosses the x- axis at (- 2, 0 )

Given ↓The equation y=3x+6To Find ↓The point where the equation → y=3x+6 ← crosses the x-axis.

Calculations ↓ Let y be 0

Instead of y write 0:

0=3x+6

Now all we have to do is solve for x :

0=3x+6

Subtract 6 on both sides :

-6 = 3x

Switch the order :

3x = -6

Divide by 3 on both sides :

x = -2

Now that we know the x coordinate of the point, we should find the y coordinate, which is always equal to 0.

apothem = 15

Area of a Hexagon

The area of a hexagon with apothem 15 can be calculated by first finding the length of the side of the hexagon.

Length of hexagon can be found using trigonometric ratio;

[tex]a = x\sqrt{3}[/tex]

Making x the subject of formula

[tex]x = \frac{a}{\sqrt{3} }\\x = \frac{15}{\sqrt{3} }\\x = 8.660[/tex]

And then the length of the side is 2x

[tex]s = 2 * 8660 = 17.32[/tex]

The perimeter of the hexagon is;

[tex]p = 6s \\p = 6 * 17.32=103.92[/tex]

And the area is given as

[tex]A = \frac{1}{2} * perimeter * apothem\\A = \frac{1}{2} * 103.92 * 15\\A = 779.4unit^2[/tex]

The area of the hexagon is 779.4 squared unit.

Area of the pentagon

The area of the pentagon can be found using several methods, but we can simply find the angle between the sides if we divide the pentagon into 10 pieces and then substitute the formula.

Total area of a pentagon is 360 degree.

[tex]\theta = \frac{360}{10} = 36^0\\[/tex]

The area of a pentagon is given as

[tex]A = \frac{5s^2}{4 tan \theta} \\A = \frac{5 * 7^2}{4* tan36} \\A = 84.303cm^2[/tex]

The area of the pentagon is 84.303cm^2

From the calculations above, the area of the hexagon and pentagon area 779.4cm^2 and 84.303cm^2 respectively

What is 7/8 - 1/4 in simplest form?

Answers

Answer: 5/8

Step-by-step explanation:

You could convert 1/4 to 2/8 because the numbers you're subtracting have a common factor of 2. After subtracting 2/8 from 7/8, you're left with 5/8.

Answer:

7/8 - 1/4 = 5/8

Step-by-step explanation:

The equation is 7/8 - 1/4 = ?

So you need to have a common denominator for both fractions in order to subtract the two.

In order to make 7/8 and 1/4 have a common denominator, multiply 1/4 by 2. Then it becomes 2/8.

Now you can subtract the two fractions because they both have a common denominator.

7/8 - 2/8 = 5/8

-11b+7 = 40−11b+7=40

Answers

Answer:

b=-3

Step-by-step explanation:

The equation, -11b + 7 = 40, can be solved using the properties of equality.

Solving For b

First, subtract 7 from both sides

-11b = 33

Then, divide both sides by -11

b = -3

Checking the Answer

We can check our answer by plugging the answer back into the original equation.

First, rewrite the equation with the answer

-11(-3) + 7 = 40

Next, multiply out the terms

33 + 7 = 40

Then, add together like terms

40 = 40

Because this is a true statement, the answer must be correct.

Order: abc 1500 mg. stock: abc 2.2 g/3 ml. how many ml(s) will you give? (round the answer to the nearest tenth)

Answers

The amount of ml required for the 1500mg order is 2.1ml

Conversion of grams to milligram

Conversion factors are used to convert units from one form to another.

Using the conversion factor

2.2g = 2200mg

x = 1500mg

Find the ratio of the expressions

2.2/x = 2200/1500
2200x = 2.2 * 1500
2200x = 3300
X = 3300/2200
x = 1.5grams

Since the dosage is 2.2 g/3 ml, then for 1.5grams

Volume required = 1.5*3/2.2
Volume required = 2.1 ml

Hence the amount of ml required for the 1500mg order is 2.1ml

The approximate length of the actual object is 1465 ft, which is closest to option D.

What is a scale factor?

The ratio of the scale of an original thing to a new object that is a representation of it but of a different size is known as a scale factor (bigger or smaller).

First, let's convert the length of the model from millimeters to inches:

372.5 mm = 372.5/10 cm = 37.25/2.54 in ≈ 14.65 in

Next, we can use the scale of the model to find the length of the actual object in feet:

0.5 in. = 50 ft.

So, 1 in. = 100 ft.

Therefore, the length of the actual object in feet is:

14.65 in x (100 ft/in) = 1465 ft

Therefore, the closest length is 1467 feet.

How to apply rigid transformations on geometrical loci

Rigid transformations are transformations in which Euclidean distances are conserved in every point of the geometrical locus. Reflections and translations are sound examples of rigid transformations.

Based on all the information given in the statement, we must apply the following vectorial formula to each vertex of the rectangle EFGH:
