Find the value of x that makes Triangle DEF~ triangle XYZ.

Answers

Answer 1

Answer:

x = 4

Step-by-step explanation:

DE / XY = EF / YZ

5 / 10 = 2x-1 / 14

cross-multiply:

10(2x-1) = 14(5)

20x - 10 = 70

20x = 80

x = 4

Answer 2

The ratio of their corresponding side will remain constant. Then the value of x is 4.

What is the triangle?

Triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.

The two triangles are ΔDEF and ΔXYZ.

It is given that the ΔDEF and ΔXYZ are similar.

Then the ratio of their corresponding side will remain constant. That is

[tex]\rm \dfrac{5}{10} = \dfrac{2x -1 }{14} =\dfrac{11}{5x +2 }[/tex]

From the first two, we have

[tex]\rm \dfrac{5}{10} = \dfrac{2x -1 }{14}\\[/tex]

On simplifying, we have the value of x

x = 4

Which account has the greater principal? Select the correct answer below and fill in the answer boxes to complete your choice.

Answers

Answer:

Step-by-step explanation:

I=Prt

11.25=A(0.03)(15/12)

11.25=A(0.0375)

A=11.25/(0.0375)

A=$300

25=B(0.05)(15/12)

25=B(0.0625)

B=25/(0.0625)

B=$400

So account B has the greater principal.

The cost c in dollars of manufacturing x bicycles at a production plant is given by th function shown below C(x)=5x^2-1000x+63,500. How many bicycles must be manufactured to minimize the cost

Answers

Answer:

100 bicycle

Step-by-step explanation:

Given the cost c in dollars of manufacturing x bicycles at a production plant expressed as C(x)=5x^2-1000x+63,500.

x is the number of bikes

To minimize the cost, dC/dx = 0

dC/dx = 10x - 1000

Since dC/dx = 0

0 = 10x - 1000

-10x = -1000

x = 1000/10

x = 100

Hence the number of bicycles that must be manufactured to minimize the cost is 100 bicycle

(3x - 1)/28 = (x + 7)/24

24(3x - 1) = 28(x + 7)

72x - 24 = 28x + 196

Suppose you make coffee and it starts off just too hot to drink, so you put it in the refrigerator temporarily to cool it off. If the original temperature is 190 degrees Fahrenheit and the refrigerator is 36 degrees Fahrenheit, what will the temperature of the coffee be after 3 minutes? (k = 0.12)

Answers

Answer:

Step-by-step explanation:

f(x)= 36( 1 - 0.12)^x. F(x)= 36(0.88)^3. f(x)= 95.04 190-95.05 = 94.95 degree.

Because the temperature is going down, we will use (1-0.12) instead of (1+0.12). X=3 because it is what temperature after 3 min. x= time.

find the length of the missing side

Answers

Answer: 55.4

Step-by-step explanation:

Remember soh cah toa

tangent = adjacent/opposite

angle is 18 degrees

Opposite is 18

Adjacent is x

So tangent of 18 degrees = 18/x

Use calculator to find tangent of 18 =0.3249

So 0.3249 = 18/x

Reciprocal both sides

3.0777 = x/18

Multiply both sides by 18

x = 55.3983

Given line 1, with coordinates (-7,-3) and (4,7), and line
2 with coordinates (7,-7) and (-3, 4), find the slope of line 2

Answers

Answer:

-11/10 (fraction) or -1.1 (decimal)

Step-by-step explanation:

The slope formula is m=(y2-y1)/(x2-x1)

x1 = 7

x2 = -3

y1 = -7

y2 = 4

So, it’s: (4 - (-7))/(-3-7)

= (4+7)/(-3-7)

= (11)/(-10)

= -11/10 or -1.1

A missing piece of a board game, a circular disk, had an area of 100,608.7, the replacement disks are listed using circumferences, what size circumference should be ordered 1. 1,124.12 mm 2. 0.7 mm 3. 179 mm 4. 1,263,645.774 mm

Answers

Answer:

1,124.12 mm

Step-by-step explanation:

Steps to answering this question :

First determine the radius of the circle from the area of the circle

Use the radius determined above to calculate the circumference

Area of a circle = nr²

where r = radius

n = pi = 3.14

100,608.7mm = nr²

to determine the radius, divide both sides of the equation by 3.14

32,040.98726mm = r²

Find the square root of 32,040.98726mm

√32,040.98726mm

r = 179mm

Circumference of a circle = 2nr

2 x 179 x 3.14 = 1,124.12 mm

Weapons of war could now be made on a mass scale because of the development of factories and assembly lines. Also, new technologies could be adapted and applied to make advanced weaponry that could cause massive casualties. For instance, the plane would become the perfect technology used to drop bombs. The industrialization and modernization of weapons made it easier for the Allies and Central Powers to kill. Hence, WWI become known as one of the bloodiest wars of all time. The total number of military and civilian casualties in World War I was more than 38 million; there were over 17 million deaths and 20 million wounded. Interestingly, early in the war, the Allies and Central Powers would both be forced to dig trenches in order to avoid being killed by new weapons of war and be over taken. Hundreds of miles of trenches stretched across the frontlines. Trench warfare would become a way of life for both sides as well as a key defensive strategy. The use of trenches would also cause a stalemate in the war where both sides struggled to make progress in the war. The use of trenches in the war would lead to designers and military engineers to develop many strange weapons and contraptions in an effort to gain an advantage in the war. Brewster Body Shield.
