Step-by-step explanation:

you would need to find the square root of the total amount of tiles. luckily 81 is a square number meaning the answer is each side is 9 tiles long.

The amount of medicine in the bloodstream remains at 80 mg for any number of hours after ingestion.

The equation y = 100(0.8) y represents the amount of medicine in the bloodstream and x represents the number of hours since the medicine was ingested.

To understand how the amount of medicine changes over time we can plug in different values for x and calculate the corresponding values of y.

Let's calculate the amount of medicine in the bloodstream at different time intervals:

For x = 0 (immediately after ingestion):

y = 100(0.8) = 80 mg

For x = 1 (1 hour after ingestion):

y = 100(0.8) = 80 mg

For x = 2 (2 hours after ingestion):

y = 100(0.8) = 80 mg

The amount of medicine in the bloodstream remains constant at 80 mg regardless of the number of hours since ingestion.

This indicates that the rate of medicine absorption into the bloodstream is not changing over time in this particular model.

3.75 quarts of paint does Argelis have left with her.

A unit of volume for measuring liquids. 1 gallon = 4 quarts = 8 pints = 16 cups = 128 fluid ounces.

Here, we know that,

1 gallons = 4 quarts

so, 1/2 gallons = 1/2 X 4 = 2 quarts.

and 1/4 gallons = 1/4 X 4 = 1 quarts.

Now, total paint left with Argelis = 1/2 gallons + 3/4 quarts + 1/4 gallons

                                                     =  2 quarts + 3/4 quarts + 1 quarts

                                                    = 3 quarts + 3/4 quarts

                                                    = 15/4 quarts or 3.75 quarts

Thus, 3.75 quarts of paint does Argelis have left with her.

The sum of the internal angles of the polygons are

a) The sum is A = 540°

b) The sum is A = 360°

c) The sum is A = 1800°

The sum of the interior angles of a polygon is given by the formula

Sum of Interior angles of a polygon with n sides is

nθ = 180° ( n - 2 )

where n is the number of sides

θ = angle in degrees

Given data ,

Let the sum of the internal angles of a polygon be represented as A

Now , the value of A is

The sum of exterior angle of n polygon is = 360°

Now ,

a)

The number of sides of the polygon = 5 sides

So , Sum of Interior angles of a polygon with n sides is

nθ = 180° ( n - 2 )

Substituting the value of n = 5 in the equation , we get

nθ = 180° ( 5 - 2 )

nθ = 180° x 3

nθ = 540°

b)

The number of sides of the polygon = 4 sides

So , Sum of Interior angles of a polygon with n sides is

nθ = 180° ( n - 2 )

Substituting the value of n = 4 in the equation , we get

nθ = 180° ( 4 - 2 )

nθ = 180° x 2

nθ = 360°

c)

The number of sides of the polygon = 12 sides

So , Sum of Interior angles of a polygon with n sides is

nθ = 180° ( n - 2 )

Substituting the value of n = 12 in the equation , we get

nθ = 180° ( 12 - 2 )

nθ = 180° x 10

nθ = 1800°

Hence , the sum of the internal angles of the polygon is solved

Answer:

The value of k is 1.

Step-by-step explanation:

x – 1 is a factor of f(x)

This means that:

x - 1 = 0

x = 1

That means that when \(x = 1, y = 0\). We use this to find the value of k.

f(x) = 3x^3 - 4x + k

\(3*1^3 - 4(1) + k = 0\)

\(3 - 4 + k = 0\)

\(k = 1\)

The probability that the next person will purchase one or more costumes as a decimal to the nearest hundredth is 0.443

Out of 217 visitors who came to Nayeli's website, none of them purchased a costume. Therefore, the number of visitors who may purchase a costume is 217 less than the total number of visitors:

Total visitors - No. of visitors who didn't purchase a costume = 217

Total visitors - 217 = No. of visitors who may purchase a costume

Total visitors = 113 + 217+36 = 336

Out of the remaining visitors, 113 purchased exactly one costume, and 36 purchased more than one costume. Therefore, the number of visitors who purchased one or more costumes is:

No. of visitors who purchased one or more costumes = 113 + 36 = 149

Therefore, the probability that the next person will purchase one or more costumes can be expressed as:

Probability = No. of visitors who purchased one or more costumes / Total visitors

Probability = 149 /336 = 0.443

The probability that the next person will purchase one or more costumes as a decimal to the nearest hundredth is 0.443

The decibel measurement for the quiet room is 54 dB.

To determine this, we first need to understand what the threshold of sound is. The threshold of sound is the minimum sound pressure level that can be heard by the human ear, and it is typically measured at 0 dB.

Next, we can use the formula for decibel measurement:

dB = 10 log (I/I0)

where I is the intensity of the sound in the quiet room, and I0 is the threshold of sound.

Since the noise in the quiet room is 500 times as intense as the threshold of sound, we can plug in the values into the formula:

dB = 10 log (500/1)

dB = 10 log (500)

dB = 10 * 2.7

dB = 27

Therefore, the decibel measurement for the quiet room is 27 dB. However, this answer is incorrect because the question states that the noise in the quiet room is 500 times as intense as the threshold of sound, not 500 times the threshold of sound.

To correct this mistake, we need to use the formula for decibel measurement with the correct values:

dB = 10 log (500 * I0/I0)

dB = 10 log (500)

dB = 10 * 2.7

dB = 27

Therefore, the decibel measurement for the quiet room is 27 dB + 27 dB = 54 dB.

Answer:

x = 90

Step-by-step explanation:

The given diagram shows a circle with intersecting chords, KM and JL.

To find the value of x, we can use the Angles of Intersecting Chords Theorem.

According to the Angles of Intersecting Chords Theorem, if two chords intersect within a circle, the angle formed at the intersection point is equal to half the sum of the measures of the arcs intercepted by the angle and its corresponding vertical angle.

Let the point of intersection of chords KM and JL be point P.

As the chords are straight lines, angle x° forms a linear pair with angle JPM.

Note: We cannot use the Angles of Intersecting Chords Theorem to find the value of x directly, since we have not been given the measures of the arcs KJ and ML. Therefore, we need to use the theorem to find m∠JPM first.

From inspection of the given diagram:

Using the Angles of Intersecting Chords Theorem, we can calculate the measure of angle JPM (shown in orange on the attached diagram):

\(\begin{aligned}m \angle JPM &=\dfrac{1}{2}\left(m\overset\frown{JM}+m\overset\frown{LK}\right)\\\\&=\dfrac{1}{2}\left(30^{\circ}+(2x-30)^{\circ}\right)\\\\&=\dfrac{1}{2}\left(30^{\circ}+2x^{\circ}-30^{\circ}\right)\\\\&=\dfrac{1}{2}\left(2x^{\circ}\right)\\\\&=x^{\circ}\end{aligned}\)

As angle JPM forms a linear pair with angle x°, the sum of the two angles equals 180°:

\(\begin{aligned}m \angle JPM+x^{\circ}&=180^{\circ}\\\\x^{\circ}+x^{\circ}&=180^{\circ}\\\\2x^{\circ}&=180^{\circ}\\\\\dfrac{2x^{\circ}}{2}&=\dfrac{180^{\circ}}{2}\\\\x^{\circ}&=90^{\circ}\\\\x&=90\end{aligned}\)

Therefore, the value of x is 90, which means that the two chords intersect at right angles.

The three points which are a solution to the equation are:

(-4,1) , (-6,5) and (-3,-1)

Given:

2x+y=-8

Solving (a): The possible coordinates.

we have:

(x,y) = (-7,-3)

⇒ 2x+y=-7

⇒ 2(-7)+(-3) = -7

⇒ -14-3 = -7

⇒-18=-7

hence (-7,-3) is not a point on the grid.

(b) (-4,1)

we have:

(x,y) = (-4,1)

⇒ 2x+y=-7

⇒ 2(-4)+(1) = -7

⇒ -8+1 = -7

⇒ -7 = -7

hence (-4,1) is a point on the grid.

(c) (-6,5)

we have:

(x,y) = (-6,5)

⇒ 2x+y=-8

⇒ 2(-6)+(5) = 8

⇒ -12+5 = -7

⇒ -7= -7

hence (-6,5) is a point on the grid.

(d) (0,3)

we have:

(x,y) = (0,3)

⇒ 2x+y=-8

⇒ 2(0)+(3) = 8

⇒ 0+3 = -7

⇒ 3= -7

hence (0,3) is not a point on the grid.

(e) (-4,6)

we have:

(x,y) = (-4,6)

⇒ 2x+y=-8

⇒ 2(-4)+(6) = 8

⇒ -8+6 = -7

⇒ -2= -7

hence (-4,6) is not a point on the grid.

(f) (-3,-1)

we have:

(x,y) = (-6,5)

⇒ 2x+y=-8

⇒ 2(-3)+(-1) = -7

⇒ -6-1= -7

⇒ -7= -7

hence (-3,-1) is a point on the grid.

Firstly we determine how many people clara will reach in 40 phone calls.

6 people=12 calls

X people=40 calls.

make X the subject of the formula.

X=(6×40)÷12=20

So clara will reach 20 people in 40 phone calls.

Now lets determine how many people Toby will reach in 40 phone calls.

7 people=13 calls

Y people=40 calls.

Therefore making Y the subject of the formula we have,

Y=(7×40)÷13=21 people.

So toby will reach more people in 40 calls
