An adult takes 400mg of vitamin c. Each hour, the amount of vitamin c in the person’s system decreases by about 29%. How much vitamin c is left after 6 hours?

Answer:

10 is your answer for c.

Step-by-step explanation:

Isolate the variable c. Note the equal sign, what you do to one side, you do to the other.

Subtract 3c from both sides:

3c (-3c) - 10 = 2c (-3c)

-10 = 2c - 3c

-10 = -c

Isolate the variable, c. Divide -1 from both sides:

(-c)/-1 = (-10)/-1

c = -10/-1

c = 10

c = 10 is your answer.

Answer:

X = 25

Step-by-step explanation:

To solve this question, we'll first of all find determine the side length of the triangle from the perimeter.

Perimeter of an equilaterial triangle = 3 * s

S = side length

Perimeter = 150cm

150 = 3s

S = 150 / 3

S = 50cm

The side lengths are 50cm each since they are all equal.

To find x,

We have to divide the triangle equally into two different part.

Check the first attachment for better illustration on how the equilaterial triangle is.

Check the second attachment for better illustration on the triangle when its divided into a right angle triangle.

From the right angle triangle, we can use pythagorean theorem to solve for x

a² = b² + c²

a = 50cm

b = 25cm

c = x√(3)

50² = [x√(3)]² + 25²

2500 = x² * 3 + 625

2500 - 625 = 3x²

1875 = 3x²

X² = 1875 / 3

X² = 625

X = √(625)

X = 25

Answer:

Volume of air in the tank =1,044 Liter

Step-by-step explanation:

Given:

Tank volume = 8 Liter

Pressure = 141 atm

Temperature = 22°C = 273° + 20° = 295° K

Find:

Volume of air in the tank = ?

Computation:

[tex]\frac{Pressure\times Tank\ volume}{Tempreture} =\frac{Pressure\times Air\ volume}{Tempreture}\\\\\frac{141\times 8}{295} =\frac{1\times Air\ volume}{273.15}\\\\\frac{1,128}{295} =\frac{Air\ volume}{273.15}\\\\Air\ volume=1,044.45[/tex]

Volume of air in the tank =1,044 Liter

Answer:

1,044 Liter

Step-by-step explanation:

Answer:

Triangle ACB = Triangle ADB

=> BC = BD

=> -2x+85 = 5x - 48

=> x = 133/7 = 19

=> BC = -2 x 19 + 85 = 47

If we are provided with the value of AC or CD, we can calculate the length of BC is 47

Let's first determine the lengths of segment BC and BD in terms of x using the given expressions:

BC (B C¯¯¯¯¯¯¯¯) = -2x + 85

BD (B D¯¯¯¯¯¯¯¯) = 5x - 48

Now, as ACB and ADB are right angles, we can utilize the property of perpendicular chords intersecting a circle to find the value of x. When two chords intersect inside a circle, the product of their segments is equal. Therefore, we can set up the following equation:

BC * BD = (AC * CD) [Property of perpendicular chords intersecting]

Substitute the values:

=> BC = BD

When we simplify this one, then we get,

-2x+85 = 5x - 48

Then the value of x is calculated as,

x = 133/7 = 19

BC = -2 (19) + 85 = 47

Answer:

(Use right triangle)

1) find the height of the waterfall (opposite side) to the nearest foot.

draw the triangle.  distance from  far side of the pool to the top of the waterfall is the hypotenuse given to be 230.

sinx = opp/hyp

sin54 = opp/230

opp = 230sin54

opp = approx 186 ft

2) find the width across the pool (adjacent side) to the nearest foot.

cosx = adj/hyp

cos54 = adj/230

adj = 230cos54

adj = approx 135 ft

Answer: 135 ft

The value of x is 135.2 feet.

To understand more, check below explanation.

From given figure,

It is observed taht, a right angle triangle is formed in the given figure.

Angle of elevation = 54 degree

Hypotenuse  = 230 feet

We have to find base i.e x

Apply cosine of angle,

               [tex]cos (54)=\frac{x}{230}\\ \\x=230*cos(54)\\\\x=230*0.587\\\\x=135.2ft[/tex]

The markup rate of 300% means the price is increased by three times the cost. So, $1.50 * 3 = $4.50 is the markup cost. Adding the original cost to the markup cost gives $1.50 + $4.50 = $6.00.

Answer:

The first term of the series is 81

Step-by-step explanation:

The sum of the nth term of a geometric sequence is expressed as shown;

Sn = a(1-rⁿ)/1-r for r<1

a is the first term

r is the common ratio

n is the number of terms

Given Sn = 171

r = 2/3

n = 3

a =?

Substituting the values in the equation

171 = a(1-(2/3)³)/1-2/3

171 = a(1-8/27)/(1/3)

171 = a(19/27)/(1/3)

171 = a × 19/27 × 3/1

171 = a × 19/9

Cross multiplying

171×9 = 19a

1539 = 19a

a = 1539/19

a = 81

The first term is 81

Answer:

308.44 miles

Step-by-step explanation:

If the two locations are on the same basic longitude, then they are both on a great circle.

Distance along great circle [tex]=\dfrac{\theta}{360^\circ}X2\pi R[/tex]

Where:

[tex]\theta=$Angular difference\\R=Radius of the earth[/tex]

Since they are on the same polar axis (North), we subtract.

Angular Difference =39° 8' 46"-34° 43'41"=4°25'5"

Therefore:

[tex]Distance =\dfrac{4\°25'5''}{360^\circ}X2*4000*\pi \\=308.44 \:miles[/tex]

The Pythagorean theorem can only be applied to right triangles.

The Pythagorean theorem can be applied to right triangles only.

It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.

So, while the Pythagorean theorem cannot be applied to every triangle, it can be used to find the length of one side of a right triangle given the lengths of the other two sides.

Answer:

After 8 hour there will be 317.64 pounds of algae.

y-intercept: (0, 50)

Step-by-step explanation:

At time = 0 hours, there are 50 pounds of algae, after 3 hour there will be 100 pounds of algae, after 6 hour there will be 200 pounds of algae, and so on.

Exponential growth is modeled by the following equation:

y = x0*(1 + r)^t

where x0 is the amount of algae at the beginning, r is the rate of change, and y is the amount of algae after t hours. Replacing with data:

100 = 50*(1 + r)^3

2 = (1 + r)^3

ln(2) = 3*ln(1 + r)

r = exp(ln(2)/3) - 1

r = 0.26

This result can be checked as follows

y = 50*(1 + 0.26)^6 = 200

After 8 hours:

y = 50*(1 + 0.26)^8 = 317.64

The y-intercept corresponds to t = 0

y = 50*(1 + 0.26)^0 = 50

Answer: [tex]y = -3x - 10[/tex]

Step-by-step explanation:

You can substitute the value "-3" for x and "-1" for y in each of the equations given. Whichever equation is correct when simplified is the line that the point (-3, -1) lies on:

[tex]-1 = -4(-3)-6\\\\-1=3(-3)+9\\\\-1=-3(-3)-10\\\\-1=5(-3)-1[/tex]

Simplifying the right side of each equation:

First equation: -1 = 6

Second equation: -1 = 0

Third equation: -1 = -1

Fourth equation: -1 = -16

The correct answer is "[tex]y = -3x - 10[/tex]".
