Can you make 142? Numbers given: 2,9,1,7,2,7,5 Using any combination the numbers above and any operations, get the total to be 142. You need to give me at least 4 different ways. You also need to show me how you know your answer is correct. Only one answer can only use two steps, all the rest must have at least three steps. You have to attempt more than just one operation.

Answers

Answer 1

Answer:

1) 2 × 2 × 5 × 7 + 9 -7×1 = 142

2) 9 × 7 × 2 + 5 × 2 + 7 - 1 = 142

3) 2 × 9² - 7 - 7 - 5 - 1 = 142

4) 2 × 7² + 9 + 7 × 5 × 1 = 142

Step-by-step explanation:

1) 2 × 2 × 5 × 7 + 9 -7×1 = 142

Multiply 2 by 2 by 5 by 7 add to 9 then subtract 7 multiplied by 1

2) 9 × 7 × 2 + 5 × 2 + 7 - 1 = 142

Multiply 9 by 7 by 2 by 7 add to 5 multiplied by 2 then add to 7 and subtract 1

3) 2 × 9² - 7 - 7 - 5 - 1 = 2 × 9² - (7 + 7 + 5 + 1) = 142

Multiply 2 by 9 raised to the power of 2 then subtract  the sum of 7, 7, 5 and 1

4) 2 × 7² + 9 + 7 × 5 × 1 = 142

Multiply 2 by 7 raised to the power of 2 then add 9 and add 7 multiplied by 5 multiplied by 1.

if my mathematics are correct the answer should be 122F

The temperature in degree Fahrenheit is (c) 122

The function is given as:

[tex]C = \frac 59(F - 32)[/tex]

When the temperature is 50 degrees Celsius, it means that:

C =50

Substitute 50 for C in [tex]C = \frac 59(F - 32)[/tex]

[tex]50 = \frac 59(F - 32)[/tex]

Multiply through by 9

[tex]450 = 5(F - 32)[/tex]

Divide both sides by 5

[tex]90 = F - 32[/tex]

In a survey of 2 comma 3002,300 people who owned a certain type of​ car, 1 comma 2651,265 said they would buy that type of car again. What percent of the people surveyed were satisfied with the​ car?

Answers

Answer:

55% of the people surveyed were satisfied with the​ car

Step-by-step explanation:

The proportion of people surveyed who were satisfied with the car is the number of people who said they would buy that type of car again divided by the total number of people survied.

The percentage is the proportion multiplied by 100.

We have that:

2,300 people surveyed

1,265 said they would buy that type of car again.

1265/2300 = 0.55

0.55*100 = 55%

Notice that each denominator is 10 based, which means we only have to move the decimal point according to the total number of zeros have the denominators. If the denominator is 10, we move the decimal point one spot to the left, if the denominator is 1000, we move the decimal point three spots to the left, and so on.

BD−→− bisects ∠ABC such that m∠ABD = (4x−5)∘ and m∠DBC = (3x+2)∘.

Find m∠ABC.

m∠ABC = ∘

Answers

Answer:

[tex]\angle ABC=(46)^{\circ}[/tex]

Step-by-step explanation:

Given: BD bisects [tex]\angle ABC[/tex]

[tex]\angle ABD=(4x-5)^{\circ}\\\angle DBC=(3x+2)^{\circ}[/tex]

To find: [tex]\angle ABC[/tex]

Solution:

A bisector of an angle divides it into angles of equal measures.

As BD bisects [tex]\angle ABC[/tex], [tex]\angle ABD=\angle DBC[/tex]

Put [tex]\angle ABD=(4x-5)^{\circ}\,,\,\angle DBC=(3x+2)^{\circ}[/tex]

[tex]\angle ABD=\angle DBC\\(4x-5)^{\circ}=(3x+2)^{\circ}\\4x-3x=2+5\\x=7^{\circ}[/tex]

So,

[tex]\angle ABD=(4x-5)^{\circ}=(4(7)-5)^{\circ}=(28-5)^{\circ}=(23)^{\circ}\\\angle DBC=(3x+2)^{\circ}=(3(7)+2)^{\circ}=(21+2)^{\circ}=(23)^{\circ}[/tex]

[tex]\angle ABC=\angle ABD+\angle DBC\\=(23)^{\circ}+(23)^{\circ}\\=(46)^{\circ}[/tex]

A bisector divides lines, angles and shapes into equal segments

The measure of angle ABC is 46 degrees

The given parameters are:

m∠ABD = (4x−5)∘ m∠DBC = (3x+2)∘

Given that line BD is the bisector of angle ABC, it means that:

[tex]\angle ABD = \angle DBC[/tex]

and

[tex]\angle ABC = 2\times \angle ABD[/tex]

So, we have:

[tex]4x - 5 = 3x +2[/tex]

Collect like terms

[tex]4x - 3x = 5 +2[/tex]

Evaluate like terms

[tex]x = 7[/tex]

Recall that

[tex]\angle ABC = 2\times \angle ABD[/tex]

So, we have:

[tex]\angle ABC = 2 \times (4x - 5)[/tex]

Substitute 7 for x

[tex]\angle ABC = 2 \times (4\times 7 - 5)[/tex]

[tex]\angle ABC = 2 \times (28 - 5)[/tex]

[tex]\angle ABC = 2 \times 23[/tex]

[tex]\angle ABC = 46[/tex]

Hence, the measure of angle ABC is 46 degrees

The rail fare £16.25 is increased by 5%; how much does the fare now co st?

Answers

Given our current rail fare of £16.25, we are looking for the price of the rail fare after a 5% increase.

To find the value of a 5% increase, we can multiply the rail fare by 1.05 since it is 5% added to the total value.

Or, we can multiply the rail fare by 5 and then divide by 100 to get how much will be added onto it.

Let's do both of them:

Increase: 5%

Equation: 1.05 x 16.25

1.05 x 16.25 = 17.06 rounded to the nearest cent

Rail Fare after 5% increase:  £17.06

Increase: 5%

Equation: (5 x 16.25)/100

81.25/100 = .81 rounded to nearest cent

Then, we add them together.

16.25 + 81 = 17.06

Rail Fare after 5% increase:  £17.06

The number of posters that Jason needs to sell so that the cost and revenue are equal will be 80. Option B is correct.

What is a function?

A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.

The amount of revenue in dollars, y, that Jason receives from selling x posters is given by the equation y = 4x. The cost of producing x posters is given by the equation y = (1/2)x + 280.

Then the number of posters that Jason needs to sell so that the cost and revenue are equal will be given as,

4x = (1/2)x + 280

4x - (1/2)x = 280

(7/2)x = 280

7x = 560

x = 80

The number of posters that Jason needs to sell so that the cost and revenue are equal will be 80.
