Answer: 5/3

Step-by-step explanation:

The scale factor is the same as the ratio of the length of a side of the image to the length of the corresponding side in the preimage.

We know that N'Q'=10 and NQ=6, so the scale factor is 10/6 = 5/3.

The width of her bedroom is x - 5

It is important to note that the formula for area of a rectangle is expressed as;

Area = lw

Where;

Now, let's substitute the values into the formula, we have;

2x²-7x-15 = (2x+3)w

Divide both sides by the coefficient of w

w = 2x²-7x-15/(2x+3)

Factorize the numerator

w = 2x²- 10x + 3x - 15/(2x+3)

Factor the common terms of the numerator

w = 2x(x - 10) + 3(x - 5)/(2x+3)

enclose the expressions

w = (2x + 3)(x-5)/(2x+3)

Divide the common terms

w = x - 5 feet

Hence, the value is x - 5

Answer: C

Step-by-step explanation:

First, take the square root of both the numerator and denominator. The numerator would then be equal to 6 a^4 b^2 and the bottom would just be sqrt7c. Since you still have a sqrt in the denominator, rationalize the fraction by multiplying sqrt7c to both the numerator and denominator to get rid of the sqrt. This would leave you with answer choice C.

Answer:

[tex]\frac{6a^4b^2\sqrt{7c}}{7c}[/tex]

Step-by-step explanation:

You can distribute radicals across division such that: [tex]\sqrt[n]{\frac{a}{b}}=\frac{\sqrt[n]{a}}{\sqrt[n]{b}}[/tex]

So you get the expression: [tex]\frac{\sqrt{36a^8b^4}}{\sqrt{7c}}[/tex]

Similarly with division, you can distribute radicals across multiplication such that: [tex]\sqrt{ab}=\sqrt{a}*\sqrt{b}[/tex], and you can do this multiple times

So our expression on top becomes: [tex]\frac{\sqrt{36}*\sqrt{a^8}*\sqrt{b^4}}{\sqrt{7c}}[/tex]

Whenever we take the square root of a base to an exponent, we simply divide the exponent by two. In general if you take the "nth" root of any base to an exponent, you divide the exponent by n, since: [tex](x^a)^b=x^{a*b}[/tex] and radicals such as: [tex]\sqrt[n]{x}=x^{\frac{1}{n}}[/tex], so you're just multiplying the two, which results in a division of "n" which in this case is 2.

So the square root of a^8 simplifies to a^4 after dividing the exponent by 2, which makes since: [tex]a^4*a^4=a^{4+4}=a^8[/tex] which exemplifies the very definition of a square root.

Applying this same logic to b^4 and just simplifying sqrt(36) regularly we get the following expression:

[tex]\frac{6a^4b^2}{\sqrt{7c}}[/tex]

We generally don't want square roots in the denominator, so we rationalize it by multiplying by the sqrt(7c)/sqrt(7c) which just simplifies to one, so we're not actually changing the value but it removes the sqrt(7c) from the denominator

[tex]\frac{6a^4b^2}{\sqrt{7c}} *\frac{\sqrt{7c}}{\sqrt{7c}}\\\\\frac{6a^4b^2\sqrt{7c}}{7c}[/tex]

and this turns out to be our solution!

Multiplying the expression 9x² - (x² - 4)² . 4 + 3x - x² will give -4x⁴ + 40x² + 3x - 64

From the information given, we want to multiply the expression 9x² - (x² - 4)² . 4 + 3x - x². This will be illustrated thus:

Distribute

Multiply the expression 9x² - (x² - 4)² . 4 + 3x - x²

Answer: y=32/x^2

Step-by-step explanation: Please mark brainilest. Since y and x^2 are inversely proportional, x^2(y)=k. K is some constant. Since they gave us an example of x and y, we can calculate k as 4*8=32. So our updated equation is y(x^2)=32. Dividing both sides by x^2 we get y=32/x^2, so we have y in terms of x

Answer:

y = 32x

Step-by-step explanation:

y = k/x^2

8 = k/2^2

8 = k/4

8×4 = 32

k = 32

y = 32x

Answer:

y = -5/9x

Step-by-step explanation:

Two points on the line; (4,-2) & (-5,3)

Finding the slope (m):

m = (3-(-2))/(-5-4)

= 5/-9

= -5/9

y = -5/9x + c

Since it passes through the origin, c = 0.

Hence, y = -5/9x

Using the Law of Detachment, the conclusion is that it is not safe to be out in the open, as the conclusion is true, since the conditional and the hypothesis are true.

The Law of Detachment is a logic axiom which states that if a conditional and the hypothesis are true, then the conclusion is also true.

Supposing a conditional statement p -> q, we have that:

For this problem, the sentence is:

"If there is lighting, then it is not safe to be out in the open."

Hence p and q are given as follows:

If a tumor is injected with 0.2 grams of iodine-125, which has a decay rate of 1.15% per day. The  exponential model representing the number of grams f of iodine-125 remaining in the tumor after t days is: m = m0e^kt.

First is to use this formula to find the t day

t = - ln (2) / k

Where,

k = decay rate = 1.15% or 0.0115

Let plug in the formula

t = - In (2) / - 0.0115

t = 60.27

t = 60 (Approximately)

Now let make use of the exponential model to find the gram

m = m0e^kt

​where,

m0 =0.2 initial mass

t = 60 time in days

k = -1.15 / 100 = -0.0115 (continuous growth rate)

m0e^kt = 0.2×e^[-0.0115×60]

= 0.2×e^(-0.69)

= 0.100g

The quotient is  Fraction 2 and 1 over 2.

A quotient is the value obtained by dividing one particular quantity by another. We can find the quotient when we are solving a division problem by multiplying the first term with the reciprocal of the second term. Reciprocal is the exchange between the numerator value and the denominator value.

(5/7) / (2/7)= (5/7) x (7/2)

By solving a system of equations, we conclude that the cost of a senior citizen ticket is $10, and the cost of a student ticket is $14.

Let's define the variables:

x =  price of a senior citizen ticket.

y = price of a student ticket.

With the given information we can write a system of equations:

10*x + 3*y = 142

14*x + 6*y = 224

To solve if we subtract twice the first equation from the second equation, we get:

(14*x + 6*y) - 2*(10*x + 3*y) = 224 - 2*142

14x + 6y - 20x - 6y = -60

-6x = -60

x = -60/-6 = 10

So each senior citizen ticket costs 10 dollars.

Now that we know the value of x, we can find the value of y:

10*x + 3*y = 142

10*10 + 3*y = 142

3*y = 142 - 100 = 42

y = 42/3 = 14

The total number of leaves that the science display have is 101 leaves.

As per the question, Thomas wants to display leaf specimens for a science fair.  Thomas has 98 leaves.

Total number of leaves Thomas have = 98

Thomas has 98 leaves, which is 3 fewer than the total needed. To calculate the total number of leaves Thomas need in the science display , we need to add 3 leaves in the total number of leaves Thomas have. So, we can write this mathematically as,

Total number of leaves that the science display have = Total number of leaves Thomas have + 3

Total number of leaves that the science display have = 98 + 3 = 101

A light-year, sometimes spelt light year, is a huge measure of length used in astronomy that is comparable to approximately 9.46 trillion kilometers (9.461012 kph) or 5.88 trillion miles (5.881012 mi). A light-year, as defined by the International Astronomical Union (IAU), is the distance that light travels in a vacuum in one Julian year (365.25 days). The phrase light-year is frequently misconstrued as a unit of time since it contains the time-measurement word "year." The light-year is most commonly used in non-specialist contexts and popular scientific publications to indicate distances to stars and other cosmic distances.
