he temperature at noon at a ski resort is 3°F. The temperature drops 8°F by midnight.
What is the temperature at midnight?

Answer: -10.49.

Step-by-step explanation:

Using order of operations PEMDAS:

4(-8+4.5)/ 6.25 + (-8.25)

= 4 * -3.5 / 6.25 - 8.25

= -14/6.25 - 8.25

=  -2.24 - 8.25

= -10.49.

Answer:

[tex]y = 6x + C[/tex]

Step-by-step explanation:

Given the system of equations

dx/dt = 6x − y  ............. 1

dy/dt = 36x − 6y ............ 2

Divide equation 2 by 1;

[tex]\dfrac{dy/dt}{dx/dt} = \dfrac{36x-6y}{6x-y} \\\\\dfrac{dy/dt}{dx/dt} = \dfrac{6(6x-y)}{6x-y}\\ \\\dfrac{dy/dt}{dx/dt} = 6\\\\\dfrac{dy}{dt}* \dfrac{dt}{dx} = 6\\\dfrac{dy}{dx} = 6[/tex]

cross multiply

[tex]dy = 6dx\\[/tex]

integrate both sides of the expression

[tex]\int\limits {dy} = \int\limits {6} \, dx \\\\y = 6x + C[/tex]

Hence the general solution to the system of equation is [tex]y = 6x + C[/tex]

Answer is D

B every integers a real number

C every integers is also an interration number.

Answer:

[tex]d = \frac{w}{48}[/tex]

If  [tex]\frac{1}{48} \\[/tex] is constant, say k

Then,

[tex]d = kw[/tex]

∴ d ∝ w

Hence, weight is proportional to the density

Step-by-step explanation:

From the question,

Let w denote the weight of the rock in pounds

s denote the size of the rock in cubic inches and

d denote the density of the rock in pounds per cubic inch.

First, we will write the equation connecting w, s, and d.

We get

[tex]density (pounds/inch^{3} ) = \frac{weight(pounds)}{size (inch^{3}) }[/tex]

That is,

[tex]d = \frac{w}{s}[/tex]

Now, given a 48-cubic-inch rock with weight w pounds, to show the proportional relation between the weight and the density, we will write

[tex]d = \frac{w}{48}[/tex]

If  [tex]\frac{1}{48} \\[/tex] is constant, say k

Then,

[tex]d = kw[/tex]

∴ d ∝ w

Hence, density is proportional to the weight OR weight is proportional to the density

Step-by-step explanation:

Answer:

L= 0.83 in

Step-by-step explanation:

Width= 1.2 in when length = 1 in

Required

Determine the length when width = 1 in

First, we need to determine the ratio

Ratio = [tex]\frac{Width}{Length}[/tex]

Ratio = [tex]\frac{1.2}{1}[/tex]

Ratio = 1.2 ---(1)

Let the required length be represented with L

So:

Ratio = [tex]\frac{Width}{Length}[/tex]

Ratio = [tex]\frac{1}{L}[/tex] ---(2)

Equate (1) and (2)

[tex]\frac{1}{L}[/tex] = 1.2

Multiply through by 1.2

L * [tex]\frac{1}{L}[/tex] = 1.2 * L

1 = 1.2 * L

Divide through by 1.2

L = [tex]\frac{1}{1.2}[/tex]

L = 0.83 in (Approximated)

Step-by-step explanation:

The answer is actually the last one :)

Using binary to decimal conversion, it is found that the numbers have the same values.

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

0011

Converting from decimal, the number is given by:

[tex]0011 = 1\times2^0 + 1\times2^1 + 0\times2^2 + 0\times2^3 = 1 + 1 + 0 + 0 = 2[/tex]

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

000011

Converting from decimal, the number is given by:

[tex]000011 = 1\times2^0 + 1\times2^1 + 0\times2^2 + 0\times2^3 + 0\times2^4 + 0\times2^5 = 1 + 1 + 0 + 0 + 0 + 0 = 2[/tex]

In both cases, the result of conversion is 2, thus, they have the same value.

A similar problem is given at https://brainly.com/question/7978210

To transform a binary number to a decimal number we need to multiply each of the components of the binary number by 2 to the power of the place value minus one, and sum all of that.

Based on this, we will see that 0011 and 000011 have the same value.

For example, the number 01 will be:

[tex]0*2^1 + 1*2^0 = 1[/tex]

The number 1010 will be:

[tex]1*2^3 + 0*2^2 + 1*2^1 + 0*2^0 = 1*8 + 1*2 = 10[/tex]

Now let's convert the two given numbers to decimals:

0011

[tex]0*2^3 + 0*2^2 + 1*2^1 + 1*2^0 = 3[/tex]

000011

[tex]0*2^5 + 0*2^4 + 0*2^3 + 0*2^2 + 1*2^1 + 1*2^0 = 3[/tex]

So exactly like in decimal numbers, adding zeros to the left side does not affect the value.

Answer:

$9

Step-by-step explanation:

$260-$170=90

90/10=9

We know that $17 * 10 = $170

c = amount of money to rent a locker.

$170 + 10c = $260

Subtract $170 from both sides.

10c = $90

Divide both sides by 10

c = $9

It cost $9 for one person to rent a locker.

Step-by-step explanation:

Using the digits 8,4,7,2,9 and 0 to write a whole Number with 7 in the thousands place and 2 in the tens place :

The whole number is 6 digits long

100 thousand

10 thousand

Thousand = 7

Hundred

Tens = 2

Unit

Also the whole number is less than 500,000

Hence, number in the 100 thousand place is less Than 5,

Hence digit in the 100 thousand place = 4

Placing either 8 or 9 in the ten thousand place will mean That Josh's whole number is greater than 480,000

Step-by-step explanation:

Recall that [tex]\cos x[/tex] is bounded between -1 and 1 for all real [tex]x[/tex], so that

[tex]-1\le \cos(5t)\le 1[/tex]

[tex]\implies-\dfrac1{5t}\le\dfrac{\cos(5t)}{5t}\le\dfrac1{5t}[/tex]

Now take the limit of each side of the inequality:

[tex]\displaystyle\lim_{t\to\infty}\left(-\dfrac1{5t}\right)\le\lim_{t\to\infty}\dfrac{\cos(5t)}{5t}\le\lim_{t\to\infty}\dfrac1{5t}[/tex]

The bounding limits are both 0, so by the squeeze theorem the desired limit is also 0.

Step-by-step explanation:

Answer:

5). x = -1

6). x = 2

Step-by-step explanation:

5). AC = (x + 10)

    AB = 5

    BC = (2x + 6)

    By segment addition postulate,

    AC = AB + BC

    (x + 10) = 5 + (2x + 6)

    x + 10 = 2x + 11

    2x - x = 10 - 11

    x = -1

6). AC = 19

    AB = 9x + 7

    BC = -3x + 20

    By segment addition postulate,

    AC = AB + BC

    39 = 9x + 7 + (-3x + 20)

    39 = (9x - 3x) + (7 + 20)

    39 = 6x + 27

    6x = 39 - 27

    6x = 12

    x = 2

    x = 2
