Answer:

The change in temperature was of -16ºF, that is, a decrease of 16ºF.

Step-by-step explanation:

At noon, the temperature was of 82°F.

By midnight the temperature had fallen to 66°F.

Change:

Final value subtracted by initial value, so

66ºF - 82ºF = -16ºF

The change in temperature was of -16ºF, that is, a decrease of 16ºF.

Answer:

It takes Garret 15 mins to remove one ft of hem.

(cause 4" for 5 mins x 3 = 12" for 15 mins)

He should multiply the number of minutes by 5 to determine the number of minutes to remove 5 ft of hem.

(15 x 5 = 75)

It will take 75 mins to remove 5 ft of hem.

Step-by-step explanation:

Step 1: Define

5(2x - 8) + 15 = -15

Step 2: Solve for x

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Here we see that -15 does indeed equal -15.

∴ x = 1 is the solution to the equation.

Answer: x=1

Step-by-step explanation:

Let's solve your equation step-by-step.

5(2x−8)+15=−15

Step 1: Simplify both sides of the equation.

5(2x−8)+15=−15

(5)(2x)+(5)(−8)+15=−15(Distribute)

10x+−40+15=−15

(10x)+(−40+15)=−15(Combine Like Terms)

10x+−25=−15

10x−25=−15

Step 2: Add 25 to both sides.

10x−25+25=−15+25

10x=10

Step 3: Divide both sides by 10.

10x/10=10/10

Answer:

A. 1200

Step-by-step explanation:

Speed in meter per minute

= (216*1000)/(3*60)

= 216000/180

= 1200

Answer:

A. 1200

Step-by-step explanation:

Distance travelled (d)

= 216 km

= 216000 m

time taken (t)

= 3 hours

= 3 * 60

= 180 min

Speed (s)

= d / t

= 216000/180

= 1200 m / min

The speed of the car is 1200 metres per minute.

In general, the multiplication proceeds the way it would if i were a variable. The difference is that i² can be replaced by -1.

Answer: 7

Step-by-step explanation:

The leading coefficient is the number before the term with the highest power in your polynomial. The coefficient is just a number or constant that is before a variable in your expression.

In this case, the highest degree in this polynomial is five. If we look at the coefficient of that term, we see that it is seven.

Answer:

uhh which 1

Step-by-step explanation:

The expressions are simplified and factored in as below.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

The expressions are simplified as,

1.

5x + 3x

= 8x

2.

2x + x

= 3x

3.

6x + 8x

= 14x

4.

9x + 3x

= 12x

5.

7x + 4x

= 11x

6.

10x + x

= 11x

7.

3x + 2 + 4x

= 7x + 2

8.

15x + 3 + x

= 16x + 3

9.

2x + 5 + 6x

= 8x + 5

10.

7x + 2x + 4

= 9x + 42

11.

18x + 3x + 9

= 21x + 9

12.

6x + x + 8

= 7x + 8

13.

21x + 15y

= 3(7x + 5y)

14.

2x + 14y

= 2(x + 7y)

15.

15x + 10y

= 5(3x + 2y)

16.

12x + 18y

= 6(2x + 3y)

17.

10x + 30y

= 10(x + 3y)

18.

6x + 14y

= 2(3x + 7y)

19.

8x + 16y

=  8(x + 2y)

20.

45x + 27y

= 9(5x + 3y)

21.

54x + 48y

= 3 (18x + 16y)

Thus,

The expressions are simplified and factored in as above.

Answer:

The equation is given by:

[tex]D(t) = 80 + 9\sin{0.2618t}[/tex]

Step-by-step explanation:

Sine function:

Has the following format:

[tex]y = A\sin{bx}[/tex]

In which A is the amplitude and [tex]\frac{2\pi}{b}[/tex] is the period.

Suppose you know the temperature is 80 degrees at midnight and the high and low temperature during the day are 89 and 71 degrees

This means that the amplitude of the sinusoidal variation function is 89 - 80 = 80 - 71 = 9. This means that [tex]A = 9[/tex]

During a 24-hour day, which means that the period is 24. So

[tex]\frac{2\pi}{b} = 24[/tex]

[tex]24b = 2\pi[/tex]

[tex]b = \frac{2\pi}{24}[/tex]

[tex]b = 0.2618[/tex]

So the variation is:

[tex]V(t) = 9\sin{0.2618t}[/tex]

Assuming t is the number of hours since midnight, find an equation for the temperature, D, in terms of t.

Initial temperature of 80, so:

[tex]D(t) = 80 + V(t) = 80 + 9\sin{0.2618t}[/tex]

Answer:

The slope is 1/2

Step-by-step explanation:

The number accompanied by the variable is the slope. It is in y=mx+b format, and m is the slope.
