bob sells televisions. he earns a fixed amount for each television and an additional $25 if the buyer gets an extended warranty. If sells 12 televisions with extended​ warranties, earns 900 How much is the fixed amount earns for each​ television

Answers

Answer:

$50

Step-by-step explanation:

25x12=300 (the amount he makes on the extended warranties)

900-300=600 (total fixed price on all 12 tvs)

600/12=$50

can someone write this equation is slope intercept form?​

Answers

Answer:

To find the slope use the distance formula. The distance formula is Y2-Y1/X2-X1.

300-100/10-2

200/8

25

So, the equation so far is y=25x+b. To  find the y-intercept, substitute one of the points into the equation.

100=25(2)+b

100=50+b

b=50

The equation of the line is y=25x+50.

:)

Answer:

y = 25x + 50

Step-by-step explanation:

The graph shows this line passing through (2, 100) and (10, 300).  Here x changes from 2 to 10, a 'run' of 8, and y changes from 100 to 300, a 'rise" of 200.  Hence the slope of this line is m = rise / run = 200/8 = 100/4 = 25.

The basic slope-intercept form is y = mx + b.  We know that m = 25.  Taking coordinate values from (2, 100), we let x = 2 and y = 100:

100 = 25(2) + b, or 100 = 50 + b.  

Therefore, the y-intercept is 50, and the desired equation in slope-intercept form is

y = 25x + 50

Step-by-step explanation:

Given:

Joakin = 0.3 Miles from Keith

Layla lives 0.4 times as far as Joakim

Solution:

If Joakin lives 0.3 miles from keith and Layla lives 0.4 times as far from keith as Joakim that mean to multiply 0.3 by 0.4.

0.3 x 0.4 = 0.12

Hence, Layla live 0.12 Miles from Keith.

My friend has $280 to spend on a fence for her rectangular garden. She wants to use cedar fencing which costs $13/foot on one side, and cheaper metal fencing which costs $7/foot for the other three sides.

What are the dimensions of the garden with the largest area she can enclose?

length for cedar side = ___foot

width for other side = ___foot

What is the largest area that can be enclosed?

area = ____foot-squared

If necessary, round your answers accurate to two decimal places.

Answers

What are the dimensions of the garden with the largest area she can enclose?

The dimensions of the garden with the largest area she can enclose are length for cedar side = 7 foot and width for other side =  10 foot

Let L = length of the fence and W = width of the fence.

Also, let L be the length of cedar fencing.

Since we require one side of cedar fencing and the other 3 sides of cheaper metal fencing, and the cedar fencing costs $13/foot and the cheaper material costs $7/foot, the total cost of fencing is C = 13L + 7L + 2W × 7

= 13L + 7L + 14W

= 20L + 14W.

Since the total amount my friend wants to spend on fencing is $280, C = 280.

So, 20L + 14W = 280

10L + 7W = 140 (1)

Also, the area of the rectangular area is A = LW

From (1), L = (140 - 7W)/10

Substituting L into A, we have

A = LW

A = (140 - 7W)W/10

A = 14W - 0.7W²

To find the value of W that makes A maximum, we differentiate A with respect to W.

So, dA/dW = d(14W - 0.7W²)/dt

dA/dW = 14 - 1.4W

Equating it to zero, we have

14 - 1.4W = 0

14 = 1.4W

W = 14/1.4

W = 10 feet

To determine if this value maximizes A, we differentiate dA/dW with respect to W.

So, d²A/dW² = d(14 - 1.4W)/dW = -1.4

Since d²A/dW² = -1.4 < 0, W = 10 feet is a maximum point.

Since L = (140 - 7W)/10,

substituting W = 10 into the equation, we have

L = (140 - 7W)/10

L = (140 - 7 × 10)/10

L = (140 - 70)/10

L = 70/10

L = 7 feet

So, the dimensions of the garden with the largest area she can enclose are length for cedar side = 7 foot and width for other side =  10 foot

What is the largest area that can be enclosed?

The largest area that can be enclosed is area = 70 foot-squared

Since the area A = LW

Substituting the values of L and W into the e quation, we have

A = LW

A = 7 × 10

A = 70 ft²

So, the largest area that can be enclosed is area = 70 foot-squared

An investigator at a crime scene found a triangular piece of torn fabric. The investigator remembered that one of the suspects had a triangular hole in their coat. Perhaps it was a match. Unfortunately, to avoid tampering with evidence, the investigator did not want to touch the fabric and could not fit it to the coat directly.
a) If the investigator measures all three side lengths of the fabric and the hole, can the investigator make a conclusion about whether or not the hole could have been filled by the fabric?
b) If the investigator measures two sides of the fabric and the included angle and then measures two sides of the hole and the included angle can he determine if it is a match? Explain.

Answers

9514 1404 393

Answer:

  a) yes

  b) yes

Step-by-step explanation:

a) Triangles can be proven congruent by the SSS postulate, so knowing the three side lengths is sufficient to demonstrate the piece will fit in the hole.

__

b) A triangle can be solved (completely specified) if two sides and the included angle are known. Those measurements on the fabric and the hole allow all side lengths and angles of the triangles to be determined completely. Hence the triangles can be shown congruent as a result.

_____

Additional comment

Showing SSS congruence generally means demonstrating corresponding sides are the same length. However, the three side lengths completely specify the triangle. The side lengths can always be made corresponding if they are listed in some order, for example, shortest to longest.

Showing SAS congruence requires that corresponding sides and angles be shown congruent. However, an SAS specification of a triangle is sufficient to permit determination of all sides and angles. Specifically, the third side length can be found using the Law of Cosines, and the remaining angles can be found from either the Law of Sines or the Law of Cosines.

Answers

Answer:

Feudalism is a system of land ownership and duties. It was used in the Middle Ages. With feudalism, all the land in a kingdom was the king's. However, the king would give some of the land to the lords or nobles who fought for him, called vassals. The term feudal system is often used in a much more general way in political rhetoric to indicate an outdated, exploitative system of government.

Step-by-step explanation:

Hope it helps

Answer:

The feudal system was introduced to England following the invasion and conquest of the country by William I, The Conqueror. Feudalism did not always work as well in real life as it did in theory, and it caused many problems for society. The feudal system is a type of social and political system in which landholders provide land to tenants in exchange for their loyalty and service. The feudal systen developed because people needed prorection from invaders since the Roman Empire had fallen. The feudal system started at the top with the kimg granting his lamd to a baron for soldiers all the way down to a peasant getting land to grow crops.
