Answer:

The answer is C!

Answer:

increase

3520268 - 3433145= 87123

87123/3433145 = 0.02537702

0.02537702 X 100 = 2.5%

Answer:

3% increase

Step-by-step explanation:

When multiplying the same number is raised to different exponents add the exponents together:

332^-6 x 332^3 = 332^(-6 +3) = 332^-3

Then when a number is raised to a negative exponent, change the exponent to a positive value and make the number a fraction, as the denominator, with 1 as the numerator:

332^-3 = 1/332^3

1/332^3 = 1/36594368

Answer:

y+2=.25(x+3)

Step-by-step explanation:

The point slope form is shown as follows

y-y₁=m(x-x₁)

We know that the slope (m) is equal to .25 and that x₁=-3 and y₁=-2

We can plug this in and get

y-(-2)=.25(x-(-3))

Simplify the signs to get

y+2=.25(x+3)

Answer:

One serving of Grapefruit juice has 41 more mg of Vitamin C than one serving of Tomato juice

Step-by-step explanation:

This question is asking for a comparison of the amount of Vitamin C is Grapefruit juice, 86 mg, and Tomato juice, 45 mg. Because the question is worded so that whichever juice has the most Vitamin C is put first, Grapefruit juice must be put first. The next part is asking for the difference in the amount of Vitamin C between Grapefruit and Tomato juice, which can be found by simplifying an expression such as 86-45. This leaves the answer being 41, which will be put in the second box. Finally, the third box is asking for the juice with the lowest amount of Vitamin C, which is the tomato juice.

Answer:

1 square unit

Step-by-step explanation:

Plug in s = 1/4 into the formula.

A = 16(1/4)^2

= 16(1/16) (since 4^2=16)

= 1 (cancel out the 16s)

Answer:

-248.15°C

Step-by-step explanation:

An object in a laboratory is cooled to 25 Kelvin. What is the temperature of the object in degrees Celsius?

The formula that converts from Kelvin to degrees Celsius =

Celsius = (Kelvin – 273.15)

Kelvin = 25K

Hence:

°C = 25 - 273.15

°C = -248.15°C

Therefore, the temperature of the object in degrees Celsius is -248.15°C

Answer: C

Step-by-step explanation:

Answer:

In equation A, x= -1 and y= 3

In equation B, x= 12 and y= 16

Step-by-step explanation:

Given the expression

(x + yi) + (4 – 7i) = 3 – 4i

We are to find the value of x and y

Expand the equation;

(x + yi) + (4 – 7i) = 3 – 4i

x + yi + 4 – 7i = 3 – 4i

x+4+yi-7i = 3 - 4i

x+4 + (y-7)i = 3-4i

Equate the real part

x+4 = 3

x = 3-4

x = -1

Equate the imaginary part;

y - 7 = -4

y = -4 + 7

y = 3

In equation A, x= -1 and y= 3

For equation B:

(x + yi) - (-6 + 14i) = 18 + 2i

x+yi+6-14i = 18+2i

x+6+(y-14)i = 18+2i

x+6 = 18

x = 18-6

x = 12

Equate the imaginary part;

y - 14 = 2

y = 2 + 14

y = 16

Hence In equation B, x=12 and y= 16

Answer:

Step-by-step explanation:

Given the expression

(x + yi) + (4 – 7i) = 3 – 4i

We are to find the value of x and y

Expand the equation;

(x + yi) + (4 – 7i) = 3 – 4i

x + yi + 4 – 7i = 3 – 4i

x+4+yi-7i = 3 - 4i

x+4 + (y-7)i = 3-4i

Equate the real part

x+4 = 3

x = 3-4

x = -1

Equate the imaginary part;

y - 7 = -4

y = -4 + 7

y = 3

In equation A, x= -1 and y= 3

For equation B:

(x + yi) - (-6 + 14i) = 18 + 2i

x+yi+6-14i = 18+2i

x+6+(y-14)i = 18+2i

x+6 = 18

x = 18-6

x = 12

Equate the imaginary part;

y - 14 = 2

y = 2 + 14

y = 16

Hence In equation B, x=12 and y= 16

I had the same question, not sure if you still need it.

Answer:

3 units

4 1/2 or - 1 1/2

Step-by-step explanation:

Given that :

Value of n is a distance of 3 units from 1 1/2 on a number line.

Recall that a number line may be divided into two parts that is the left and righmosr portions with 0 as the mid point.

Hence a value of 3 units from 1 1/2 may be to the right (positive) or to the left(negative side of the line).

Therefore :

1 1/2 + 3 = 4 1/ 2

1 1/2 - 3 = - 1 1/2

The value n will result in a distance of 3 units in either way and could be either 4 1/2 or - 1 1/2

Answer:

0.156

Step-by-step explanation:

4.5 x 10.4 = 48.6 and that divided by 300 give u ur answer.

Hope this helps!

The value of the expression (4.5 x 10^4) divided by (300) is 150.

"It is an expression which is made up of variables, constants and some mathematical operations."

For given example,

We have been given an expression (4.5 x 10^4) divided by (300)

We need to find the value of given expression.

(4.5 x 10 ^4) divided by (300)

=  (4.5 × 10000)/300

= 45000/300

= 150

Therefore, the value of given expression (4.5 x 10^4) divided by (300) is 150.

[tex]x\le \:-2\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:-2\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-2]\end{bmatrix}[/tex]

Please check the attached number line graph.

The number line clearly indicates that the graph is heading towards negative infinity from -2.

Step-by-step explanation:

Given the inequality expression

x ≤ -2

The inequality symbol ' ≤ ' means 'less than or equal to'.

Thus,

x ≤ -2 means x is less than or equal to -2.

In other words,

[tex]x\le \:-2\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:-2\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-2]\end{bmatrix}[/tex]

Hey there!

In order to simplify this expression, all we have to do is multiply 4 times x and -2:

4x-8

Notes:

[tex]\circ[/tex] We can't simplify this expression anymore, because 4x and -8 are not like terms.

[tex]\circ[/tex] A negative times a positive is a negative.
