7. The milligrams of aspirin in a person's body is given by the equation a = 500 - (3/4)
where t is the number of hours since the patient took the medicine.

b. In the equation, what does the 500 tell us about the situation?

c. In the equation, what does the tell us about the situation?

d. Graph the equation for values of t between 0 and 4.

Answer: A. 40%

amount achieved: 600/1000 = 3/5

amount not achieved = 2/5

2/5 as percent is 40%

Answer:

25; 15^2+20^2=625. 25^2=625, therefore the answer is 25.

Can you post a picture of the triangle? it would make this way easier.

Answer:

B = -1

Your answer would be C

Answer:

b = -1

Step-by-step explanation:

-3(2x - 3) + 5x = bx + 9

-3 x 2x = -6x

-3 x -3 = 9

-6x + 9 + 5x = bx + 9

-6x + 5x = -1x

-1x + 9 = bx + 9

(cancel out everything except -1 and b)

-1 = b

Answer:

It would be B (15x + 20x)

Answer:

3.913%

Step-by-step explanation:

We are given that Sheila earned is commission $900 for selling $23,000 worth of jewelry, and we are asked to find the rate of her commissions as a percent.

The rate of commissions would basically just be what percent of the money made does she get. Since Sheila sold $23,000 worth of jewelry and got $900 for doing so, her rate of commission would be:

900 ÷ 23,000 ≈ 0.03913

Which expressed as a percent is:

3.913%

So her rate of commissions would be 3.913%.

I hope you find my answer to be helpful. Happy studying.

Answer: True for all x

Step-by-step explanation:

4x - 6 + 2x = 3(2x-2)

Group Like Terms: 4x+2x - 6 = 3(2x-2)

Add Similar Elements (4x+2x=6x): 6x - 6 = 3(2x-2)

Expand: 3(2x-2) ; 6x - 6

6x - 6 = 6x - 6

Add 6 to Both Sides: 6x - 6 + 6 = 6x - 6 + 6t: 6x - 6x = 6x - 6x

Simplify: 6x = 6x

Subtract: 6x - 6x

Simplify: 0 = 0

Both sides are equal in this equation, therefore all values for x is true.

Answer:

26.75 so 27

Step-by-step explanation:

214 divided by 8 = 26.75

Answer:

27 boxes

Step-by-step explanation:

214 ÷ 8 = 26.75

Because you can't get .75 of a box, Jacob needs at least 27 boxes.

Answer:

3a+5b

Step-by-step explanation:

Variable 1:  a = candy corn

Variable 2: b = chocolate

Inequality 1:  60 ≥ 3a + 5b

Inequality 2: 20 ≤ 3a + 5b

The inequalities are as such because Josh needs to spend no greater than $60.  He must also buy at least 20 bags of candy.  The candy corn costs $3, while the chocolate costs $5.  An expression for the total cost of the candy would be 3a + 5b.

Answer:

Width=6 Length=36

Step-by-step explanation:

The stage is rectangular since the length is not equal to width.

We use the formula (Width × Length) to obtain the area of any rectangle.

But the Length is 6 times the Width, therefore we equate the formula for the area of stage as

Width × 6Width = 216

we get Width as 6 and 6width which is the length as 36

Answer:

The fourth vertex must be located at [tex]Z(x,y) = (4, -1)[/tex]. The graph of the figure is included below.

Step-by-step explanation:

Let be [tex]X(x,y)[/tex], [tex]Y(x,y)[/tex], [tex]Z(x,y)[/tex] and [tex]W(x,y)[/tex] so that a rectangle is formed. Hence, we must satisfy the following conditions:

[tex]X(x,y) = (a, c)[/tex] (1)

[tex]Y(x,y) = (a, d)[/tex] (2)

[tex]Z(x,y) = (b, c)[/tex] (3)

[tex]W(x,y) = (b, d)[/tex] (4)

[tex]a < b[/tex] (5)

[tex]c < d[/tex] (6)

If we know that [tex]a = -1[/tex], [tex]b = 4[/tex], [tex]c = -1[/tex], [tex]d = 1[/tex], then we have the following points:

[tex]X(x,y) = (-1, -1)[/tex]

[tex]Y(x,y) = (-1, 1)[/tex]

[tex]Z(x,y) = (4, -1)[/tex]

[tex]W(x,y) = (4,1)[/tex]

Then, the fourth vertex must be located at [tex]Z(x,y) = (4, -1)[/tex].

Given:

The area model for [tex]2.1\times 3.2[/tex].

To find:

The value of [tex]2.1\times 3.2[/tex] and the missing values in the area model.

Solution:

2.1 can be written as 2 and 0.1 on the left side of the area model.

3.2 can be written as 3 and 0.2 on the top of area model.

Area of the four parts of the area model are:

[tex]2\times 3=6[/tex]

[tex]2\times 0.2=0.4[/tex]

[tex]0.1\times 3=0.3[/tex]

[tex]0.1\times 0.2=0.02[/tex]

The complete area model is shown below.

After adding all areas of the area model, we get

[tex]6+0.4+0.3+0.02=6.72[/tex]

Therefore, the value of [tex]2.1\times 3.2[/tex] is 6.72 and the missing values of the area model are 0.3 and 0.02 respectively.
