At 1 pm one day the temperature inside a freezer was -20°C
The freezer broke down.
The temperature inside the freezer went up by 4°C every hour after 1pm.
At what time did the temperature inside the freezer reach 0°C?

the ship is 472 m from the lighthouse

Step-by-step explanation:

from the question, we can know ∠OAS = 90°-23° =67° and AO = 200m

OS = A0 • tan 67°

= 200 m • 236°

= 472 m

Explanation:

Let x be the unknown positive integer.

The square roots of x are [tex]\sqrt{x}[/tex] and [tex]-\sqrt{x}[/tex], representing the positive and negative square roots respectively.

Taking the difference of those means we subtract:

[tex]\text{PositiveRoot}-\text{NegativeRoot} = \sqrt{x} - (-\sqrt{x}) = \sqrt{x}+\sqrt{x} = 2\sqrt{x}[/tex]

Set that equal to 40 and solve for x

[tex]2\sqrt{x} = 40\\\\\sqrt{x} = 40/2\\\\\sqrt{x} = 20\\\\x = 20^2\\\\x = 400[/tex]

Therefore, the integer we're after is 400.

The positive square root of such is [tex]\sqrt{x} = \sqrt{400} = \sqrt{20^2} = 20[/tex]

And the negative square root is [tex]-\sqrt{x} = -\sqrt{400} = -\sqrt{20^2} = -20[/tex]

The difference of which is:

(Positive Root) - (Negative Root) = 20-(-20) = 20+20 = 40

This helps confirm the answers.

Answer:

31

Step-by-step explanation:

p = 8

p + 23

= 8 + 23

= 31

31 is the answer.

The answer is B. Since the graph increases by 4 on the y-axis as x increases by 1, the constant of proportionality is 4.

Answer:

-1/8

Step-by-step explanation:

(-1/2)^3 = (-1/2) * (-1/2) * (-1/2) = -1/8

Answer:

Since yearly, without the bonus, you would make a certain amount by multiplying $2,000 to a year, which is 12 months.

2000 × 12 = 24,000 a year.

That would be $24,000 a year.

Next, we can add 10,000 to the amount, since you are not getting paid that much for a year. It is just a "...plus...", a bonus.

24,000 + 10,000 = 34000

Therefore, the yearly salary rate will be $34,000 a year.

Let's separate this out and multiply the coefficients first, then the variables.

2 1/3 = 7/3

7/3 * -3/7 = -1

(a^2)(x)(a^3)(x^2)

When we multiply terms with exponents, we ADD the exponents.

(a^5)(x^3)

Answer: (-1)(a^5)(x^3)

Coefficient: -1

a.) Initial cost of renting the car is $100

b.) rate of change is slope, that is :

c.) Cost = C and distance = d

the equation will be :

==========================================================

Explanation:

m = number of men

w = number of women

The ratio of men to women is 7 to 5, meaning that m/w = 7/5

Cross multiply to get 5m = 7w.

Then divide both sides by 5 to end up with m = 7w/5 which is the same as m = 1.4w

We'll use this equation later.

------------------

Since there are 336 total workers, we know that:

m+w = 336

1.4w+w = 336 .... replace m with 1.4w

2.4w = 336

w = 336/(2.4)

w = 140 women work at the company

and m = 1.4*w = 1.4*140 = 196 men work at the company as well.

------------------

Checking the answer:

m+w = 196+140 = 336

m/w = 196/140 = (7*28)/(5*28) = 7/5

This helps confirm we have the correct value of w.

Answer:

82

Step-by-step explanation:

33 + (-5) - (-70) - 26

33 - 5 + 70 - 26

- and - = +

- and + = -

+ and - = -

33 -5 = 28

28 + 70 = 108

108 - 26 = 82

Answer:

x= -11

Step-by-step explanation:

Rearrange terms

[tex]-1=\frac{5+x}{6} into -1=\frac{x+5}{6}[/tex]

Multiply all terms by the same value to eliminate fraction denominators

[tex]-1=\frac{x+5}{6} \\6(1)=6(\frac{x+5}{6} )[/tex]

Cancel multiplied terms that are in the denominator

[tex]6(-1)=6 (\frac{x+5}{6} )6(-1)=x+5[/tex]

Multiply the numbers

[tex]6(-1)=x+5\\-6=x+5[/tex]

Subtract 5 from both sides of the equation

[tex]-6=x+5\\-6-5=x+5-5[/tex]

Simplify

(6x3)(1/2)=9

Answer:

a) line 3 because the coefficient of the term 5x, the slope is the greatest slope.

b) line 1 and 4 are parallel because they have the same slope: 2

c) line 1 with line 2 and line 4 with line 2 are perpendicular lines because their slopes are reciprocals negative.

d) line three crosses the y line at point 11

Step-by-step explanation:

Line 1. y = 2x - 3

Line 2: y = -2x + 3

Line 3: y = 5x + 11

Line 4: y = 2x - 10
