Answer:

25 x 0.84 ^ h = X

After 4 hours there will be 12.45 milligrams of the medicine, and after 8 hours there will be 6.20 milligrams of it.

Step-by-step explanation:

Given that a particular medicine decays at a rate of 16% every 4 hours, if a person takes a 25 mg dose, to write a function that represents the amount of medicine after h hours, and determine how much is left after 4 hours and 8 hours, the following calculations must be performed:

100 - 16 = 84

25 x 0.84 ^ h = X

25 x 0.84 ^ 4 = X

25 x 0.4978 = X

12.45 = X

25 x 0.84 ^ 8 = X

25 x 0.2478 = X

6.20 = X

Therefore, after 4 hours there will be 12.45 milligrams of the medicine, and after 8 hours there will be 6.20 milligrams of it.

Step-by-step explanation:

ASSUME the pyramid is a square right pyramid.

height = 15"

base side length = 11"

(Following edited/corrected thanks to cwrw238)

Slant height

= sqrt(5.5²+15²)   using Pythagoras theorem

= sqrt(255.25)

=  15.98"

Answer:

Slant height = 15.98 in to nearest hundredth.

Step-by-step explanation:

Use Pythagoras theorem.

The triangle we want  has a height of 15 , base of 1/2*11 = 5.5 and we need the length of the hypotenuse.

h^2 = 5.5^2 + 15^2 = 255.25

h = 15.976.

Answer: Choice A)  Add 3.8 to both sides of the equation

Explanation:

If we knew the value of w, then we would replace it and apply PEMDAS.

However, we don't know the value of w, so we undo each step of PEMDAS going backwards.

We start with the "S" of PEMDAS, and undo the subtraction. To undo subtraction, you apply addition. To undo that "minus 3.8" we add 3.8 to both sides.

Answer:

Add 3.8 to both sides of the equation.

Step-by-step explanation:

The method of inverse operations is the process in which one systematically undoes operations in an equation so that one can solve for an unknown quantity in an equation. Typically, one does inverse operations in the opposite order of the order of operations. Remember, the order of operations is as follows,

1. Parenthesis

2. Radicals and Exponents

3. Multiplication and Division

4. Addition and Subtraction

When solving an equation, one uses the order of operations from least to greatest do operations with step (1) first, then step (2), and so on. However, when doing inverse operations, one uses the order of operations from greatest to least. Therefore, one does the opposite of the operations with step (4) first, then step (3), and so on.

In the given equation,

1.2m - 3.8 = 12.4

One has an operation of subtraction, when doing inverse operations, this is the first. The opposite of subtraction is addition, therefore one will add (3.8) to both sides to undo this operation.

Answer: $1.24, $2.22

Step-by-step explanation:

Suppose one yoyo and 1 toy car costs x and y respectively.

According to question

5 yoyos and 2 toy cars costs $10.64

[tex]\Rightarrow 5x+2y=10.64\quad \ldots(i)[/tex]

4 yoyos and 4 toy car costs $13.84

[tex]\Rightarrow 4x+4y=13.84\quad \ldots(ii)[/tex]

Solve (i) and (ii)

[tex]x=1.24,y=2.22[/tex]

Thus, 1 toy car costs $2.22

Answer: [tex]x=2[/tex]

Step-by-step explanation:

Let's solve your equation step-by step

[tex]3(4-2x)=x-2[/tex]

First we need to use the distributive property

[tex](3)(4)-(3)(2x)=x-2\\-6x+12=x-2[/tex]

Now let's subtract x from both sides

[tex]-6x+12-x=x-2-x\\-7x+12=-2[/tex]

Next let's subtract 12 from both sides

[tex]-7x+12-12=-2-12\\-7x=-14[/tex]

Finally divide both sides by -7

[tex]\frac{-7x}{-7} =\frac{-14}{-7} \\x=2[/tex]

The answer is 3.2

Hope this answer is right!

Step-by-step explanation:

so first we do 50-11.50-3.75+5. to simplify it 55-15.25

if u do the math that equals 39.75

to double check 39.75+15.25=55

Answer:

4x+8y=64

8x+16y=128

4x/4=64-8y/4

X=64-8y/4

x=16-8y

8(16-8y)=128

128-64=128

-64y/-64=128-128

y=0

x=16-8(0)

X=16

Answer and Step-by-step explanation:

A) The first three terms are:

5, 8, 11

B) The tenth term is 32

You find the answer by plugging in the value for n. So for A), you would plug in 1, 2, and 3 (the first 3 terms), then to find the tenth term, you plug in 10 for n.

Answer:

The answer is below

Step-by-step explanation:

The ramp has the form of a triangle. The height of the ramp is the vertical side of a triangle, the top of the frame is the hypotenuse while the length of the ramp is the base side of the triangle.

Let the hypotenuse be b, length be a and height be c Hence:

b² = a² + c²

b² = 3² + 5²

b² = 9 + 25

b² = 34

b = 5.83 feet

B) The plywood needs to be 5.83 feet long

C) Since the top of the ramp is 10 feet, let us assume the height of the ramp to be 6 feet, hence, the length of the ramp a is:

10² = a² + 6²

100 = a² + 36

a² = 64

a = 8 feet

Answer:

0.1007

Step-by-step explanation:

Given :

Average gain, μ = 0.8

Standard deviation, σ = 0.7

Number of companies, n = 20

Obtaining the standardized value ;

Zscore = (x - mean) / (σ/√n)

Zscore = (1 - 0.8) / (0.7/√20)

Zscore = (0.2 / 0.1565247)

Z = 1.27775

Using the Z probability calculator :

P(Z > 1.27775) = 0.10067

P(Z > 1.27775) = 0.1007 ( Z probability calculator)

(x-4)²+(y-6)² =100 is the equation of the circle with a center of (4,6) and a radius of 10 units

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

The standard equation of a circle is (x-h)²+(y-k)² =r²

In the equation (h, k) represents the center of the circle.

r is the radius of the circle.

From given that circle with a center of (4,6) and a radius of 10 units.

We need to find the equation of the circle.

Substitute h=4, k=6 and r=10

We get  (x-4)²+(y-6)² =10²

Hence,   (x-4)²+(y-6)² =100 is the equation of the circle with a center of (4,6) and a radius of 10 units.

Answer:

The area of the shaded region is: 32.25m^2

Step-by-step explanation:

Given

See attachment for rectangle and semicircles

Required

The shaded region

We have:

[tex]l =30[/tex] --- length of the rectangle

This means that the diameters of the three circles add up to 30m.

So, the diameter of 1 is:

[tex]d = l/3[/tex]

[tex]d = 30/3[/tex]

[tex]d = 10[/tex]

The area of one circle is:

[tex]A_1 = \pi * \frac{d^2}{8}[/tex]

[tex]A_1 = 3.14 * \frac{10^2}{8}[/tex]

[tex]A_1 = 3.14 * \frac{100}{8}[/tex]

[tex]A_1 = 39.25m^2[/tex]

The area of the three circles is:

[tex]A_2 = 3 * A_1[/tex]

[tex]A_2 = 3 *39.25m^2[/tex]

[tex]A_2 = 117.75m^2[/tex]

The area of the rectangle is:

[tex]A_3 = 30 * r[/tex]

Where r is the radius of the circle

And

[tex]r =d/2[/tex]

[tex]r =10/2[/tex]

[tex]r =5[/tex]

So, we have:

[tex]A_3 = 30 * r[/tex]

[tex]A_3 = 30 * 5[/tex]

[tex]A_3 = 150[/tex]

So, the shaded region is:

[tex]A_4 = A_3 - A_2[/tex]

[tex]A_4 = 150 - 117.75[/tex]

[tex]A_4 = 32.25m^2[/tex]
