Simplify the following expression: a + 2c − 5b − c + a − b 2a − 6b + 2c 2a − 6b + c a − 6b + c a − 5b + 2c

Answer:

The temperature of the solution after 3 hours rounded to the nearest whole degree is -6 C

Step-by-step explanation:

From the question, the temperature of the chemical solution at the start of the experiment is -14.96 C.

Now, if the temperature increases by 2.9 C each hour,

Then, after 3 hours, the temperature of the chemical solution would have increased by

2.9 C/h × 3 h

8.7 C

Hence, the temperature of the chemical solution would have increased by 8.7 C after 3 hours.

The temperature of the chemical solution after 3 hours will be

-14.96 C + 8.7 C

= -6.26 C

≅ -6 C (to the nearest whole degree)

Answer: About 175 homeruns

Step-by-step explanation:

For every 135 games played, he hit 22 home runs, which makes an average of 1 home run every 6.136 games. Take that number and divide 1075 by it.

1075 / 6.136 = about 175.

Carlos Gonzales hits 175 runs in his total of 1075 games in his career.

Ratio basically compares quantities, that means it shows the value of one quantity with respect to the other quantity.

If a and b are two values, their ratio will be a:b,

Given that,

Number of games played by Carlos Gonzales = 135.

And runs hit by Carlos Gonzales = 22 runs.

To find the runs hit by Carlos Gonzales in 1075 games,

Use ratio property,

In 135 games = 22 runs hit,

in 1 game = 22 / 135 runs hit,

In 1075 games = (22/135)x1075 = 175.18 = 175 (approx)

The runs hit by Carlos Gonzales in 1075 games is 175.

Answer: The sum of the average ticket prices for movies B, D and E is $25.75.

Step-by-step explanation:

$7.57 + $8.46 + $9.72 = $25.75.

To convert mm to m, divide by 1000:

794/1000 = 0.794 m

1 day = 24 hours

1 hour = 3600 seconds

24 x 3600 = 86,400 seconds in a day

Answer:

Step-by-step explanation:

To convert 794mm into m

1000mm = 1m

794mm = xm

m = 794/1000

m = 0.794m

One day to secs is

Answer:

Coordinates of the point P are [tex](-\frac{29}{7},-1)[/tex]

Step-by-step explanation:

If a point P(x, y) divides the line AB into the ratio of m : n, coordinates of this point will be,

x = [tex]\frac{mx_2+nx_1}{m+n}[/tex]

y = [tex]\frac{my_2+ny_1}{m+n}[/tex]

In the given question m : n = 3 : 4

And the coordinates of A and B are (-5, -4) and (-3, 3) respectively.

x = [tex]\frac{3(-3)+4(-5)}{3+4}[/tex]

x = -[tex]\frac{29}{7}[/tex]

y = [tex]\frac{3(3)+4(-4)}{3+4}[/tex]

y = -1

Therefore, coordinates of the given point P are [tex](\frac{29}{7},-1)[/tex].

Answer:

x = sqrt(17)

Step-by-step explanation:

Since this is a right triangle we can use the Pythagorean theorem

a^2 + b^2 = c^2

Let the unknown side be x

8^2 + x^2 = 9^2

64 + x^2 = 81

Subtract 64 from each side

x^2 = 81-64

x^2 =17

Taking the square root of each side

x = sqrt(17)

Answer:

x = √17

Step-by-step explanation:

Your question have a right triangle.

So, we could use the Pythagorean Theorem.

Pythagorean Theorem is a² + b² = c².

So, 8² + n² = 9².

8² is 64, and 9² is 81.

So, 'n' is 81 - 64.

Let's see... 81 - 64 is 17.

So, It is √17.

Because when you use the Pythagorean Theorem, it is 8² + (√17)² = 9².

Otherwise, 64 +  (√17)² = 81.

And, √17 is 4.12 when rounding to a hundredth.

Step-by-step explanation:

For us to represent the inequality of the equation for the number of hours worked. let us identify the parameter involved the.

daily earnings in tips = $15

normal daily pay=>$110

number of hours worked is represented by h

Hence the equation for the pay is

15 h + 9 >=110

Note: we use the >= symbol in the equation because $110 is the minimum amount Serena will always receive any amount she must receive must always be greater than $110

Answer:

a = 30°

Step-by-step explanation:

Sum of the angles in a triangle is 180°

32° + 2a - 17 + 180° - ( a + 45° ) = 180°

32 + 2a - 17 = a + 45

a = 45 + 17 - 32

Step-by-step explanation:

By the property of intersecting tangent and secant outside of the circle, we have:

x° = 1/2[(4x+5)° - 50°]

2x° = [(4x+5)° - 50°]

2x° = (4x-45)°

2x = 4x - 45

45 = 4x - 2x

45 = 2x

x = 45/2

x = 22.5

Something like this

Step-by-step explanation:

distance √(-1 - 5)² + (-6 - -4)² = √36 + 4 = √40 = 6.32

slope = 2/-6 = -1/3

distance (-1,-4) to (0, -4.63)

√(-1 - 0)² + (-4 - -4.63...)² = √1.4 = 1.18

6.32 - 1.18 = 5.14
