Answer 1

Answer:

[tex] x = \dfrac{-1 \pm \sqrt{11}}{2} [/tex]

Step-by-step explanation:

(2x - 3)² - 14 = 2x(x - 7)

4x² - 12x + 9 - 14 = 2x² - 14x

2x² + 2x - 5 = 0

[tex] x = \dfrac{-2 \pm \sqrt{2^2 - 4(2)(-5)}}{2(2)} [/tex]

[tex] x = \dfrac{-2 \pm \sqrt{4 + 40}}{4} [/tex]

[tex] x = \dfrac{-2 \pm 2\sqrt{11}}{4} [/tex]

[tex] x = \dfrac{-1 \pm \sqrt{11}}{2} [/tex]

What is the value of x in the equation −6 + x = −3? (5 points) Group of answer choices −9 −3 9 3

Answers

Answer:

The value of x is 3

Step-by-step explanation:

=> −6 + x = −3

=> x = -3+6

=> x = 3

-6 + x = -3
So first you add the 6 to both sides

-6 + x = -3
+6 +6

The 6 will cancel

So your answer is
x= 3

The more people living in an area, the more likely it is that public buses will be used. city a has a population of 51,242 and covers an area of 89.22 mi2. city b has a population of 50,178 and covers an area of 8.12 mi2. which statement about use of public buses in the cities is most likely true? the residents of city a are more likely to use public buses because their city has a greater population density. the residents of city b are more likely to use public buses because their city has a greater population density. the residents of both cities are equally likely to use public buses because both population densities are about the same. the residents of both cities are unlikely to use public buses because both population densities are too high.

Answers

The population density of city-B is greater, so, the public bus must be used for city-B.

What is the population density?

Population density (in agriculture: standing stock and standing crop) is a measurement of population per unit area.

The total population of city A= 51,242

The total area of city A =89.22 mi^2

The population density of city A is given by;

[tex]\rm Population \ density=\dfrac{Total \ population }{Total \ Area}\\\\ Population \ density=\dfrac{51,242}{89.22}\\\\ Population\ density=574.3331[/tex]

The total population of city B = 50178

The total area of city B =8.12 mi^2

The population density of city B is given by;

[tex]\rm Population \ density=\dfrac{Total \ population }{Total \ Area}\\\\Population \ density=\dfrac{50178}{8.12}\\\\Population \ density=6179.55665[/tex]

Hence, the population density of city-B is greater, so, the public bus must be used for city-B.

Answer:

[tex]\boxed{\bf \angle A=84^o}[/tex]

Step-by-step explanation:

From the given diagram, we can see that ∠B & ∠C are corresponding angles, which means that they are equal. The two angles that form a straight line are supplementary angles (the sum of two supplementary angles is 180°).

[tex]\bf 5x+34^o+\angle C=180^o[/tex]

[tex]\bf 5x+34^o+\angle B=180^o[/tex]

[tex]\bf 5x+34^o+2x+76^o=180^o[/tex]

Now, let's solve for x :-

[tex]\bf (5x+34^o)+(2x+76^o)=180^o[/tex]

[tex]\bf (5x+2x)+(34+76)=180^o[/tex]

[tex]\bf 7x+110=180^o[/tex]

[tex]\bf (7x+110)-110^o=180-110^o[/tex]

[tex]\bf 7x=70^o[/tex]

[tex]\bf \cfrac{7x}{7} =\cfrac{70}{7}[/tex]

[tex]\boxed{\bf x=10^o}[/tex]

Now, in order to find ∠A will substitute the value of x into the expression:-[tex]\bf \angle A=5x+34^o[/tex]

[tex]\bf \angle A=5(10)+34^o[/tex]

[tex]\bf \angle A=84^o[/tex]

Hunter earned a grade of 66% on his multiple choice math final that had a total of 200 problems. How many problems on the final exam did Hunter get wrong?

Answers

Since the total number we are dealing with is 200, and our final percentile grade is a 66%, we can estimate already that he missed under half the questions, which means he has a score that is over 100/200, or 50%. But its not too much higher because 130/200 would be a little too much, however if we add two more points we would have a 132/200, which is equivalent to 66%

There are 68 problems on the final exam did Hunter get wrong.

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

Hunter earned a grade of 66% on his multiple choice math final that had a total of 200 problems.

Now,

Since, Hunter earned a grade of 66% on his multiple choice math final that had a total of 200 problems.

Hence, The correct problem = 66% of 200

= 66/100 x 200

= 66 x 2

= 132

Thus, The incorrect question = 200 - 132

= 68

Therefore, There are 68 problems on the final exam did Hunter get wrong.

An equation is an expression that shows the relationship between two or more numbers and variables.

From the circle graph, percentage of the people surveyed exercise once a week or less = 100% - (10% + 40% + 20% + 14%) = 16%

Determine if \sqrt{41}
41

is rational or irrational and give a reason for your answer.

Answers

Assume √41 is rational, so that there exist integers p, q such that

[tex]\sqrt{41} = \dfrac pq[/tex]

and p/q is irreducible. Taking squares, this would mean

[tex]41 = \dfrac{p^2}{q^2} \implies p^2 = 41q^2[/tex]

This tells us that 41 is a factor of p², which in turn means 41 is a factor of p because 41 is prime. We can consequently write p = 41n for some integer n. But then

[tex]p^2 = (41n)^2=41q^2 \implies 41n^2 = q^2[/tex]

which says 41 also divides q² and hence divides q as well. In other words, p/q is reducible, so we have a contradiction.

PLS HELP ASAP

Answers

Answer:

15/8 Hours

Step-by-step explanation:

To start, I would find see how long it takes to walk a mile.

1/3 · 3 = 1

1/4 · 3 = 3/4

So we now know that walking one mile takes 45 minutes. Next, I multiplied 1 mile by 2.5 and repeated the same process with the time.

3/4 · 5/2 = 15/8

Therefore, it takes 15/8 hours to walk 2.5 miles.

The face value of the largest 20-year term policy which Maria can buy without spending more than $300 annually is $158,000.

What is face value?

Face is the term used in finance, is used for the amount which has to be paid to the policyholder at the time of maturity.

Maria, age 28, wants to pay no more than $300 a year in life insurance.

The period for this policy is 20-year term.

Annual life insurance premium (per 1,000 dollars of face value) for age 28.

A 10-year term for female is 1.28, A 15 year term for female is 1.54, A 20 year term for female is 1.89, A whole life for female is 9.46.

For the 20 year term for female is 1.89 and annular premium is $300. Thus, the face value is,

[tex]\rm Face \; Value=\dfrac{300}{1.89}\times1000\\\rm Face \; Value\approx158000[/tex]

Thus, the face value of the largest 20-year term policy which Maria can buy without spending more than $300 annually is $158,000.
