Answer:

Part a) The estimate amount of medicine is 30.0 grams

Part b) The actual amount of medicine is 29.925 g. The difference between the  estimate and the actual amount, is 0.075 g

Part c) 5.985 grams

Part d) 6 grams

Step-by-step explanation:

The complete question is

Dr. Mann mixed 10.357 g of chemical A, 12.062 g of chemical B, and 7.506 g of chemical C to make 5  doses of medicine.

a. About how much medicine did he make in grams? Estimate the amount of each chemical by  rounding to the nearest tenth of a gram before finding the sum. Show all your thinking.

b. Find the actual amount of medicine mixed by Dr. Mann. What is the difference between your  estimate and the actual amount?

c. How many grams are in one dose of medicine? Explain your strategy for solving this problem.

d. Round the weight of one dose to the nearest gram

Part a) round  to the nearest tenth of a gram first

Chemical A

10.357 g -----> 10.4 g

Chemical B

12.062 g -----> 12.1 g

Chemical C

7.506 g -----> 7.5 g

To find out the estimate amount of medicine sum the three values

10.4+12.1+7.1=30.0 g

therefore

The estimate amount of medicine is 30.0 grams

Part b)

The actual amount of medicine is

10.357+12.052+7.506=29.925 g

To find out the difference between your  estimate and the actual amount, subtract the actual amount from the estimate

30.0-29.925=0.075 g

Part c) To find out how many grams are in one dose of medicine, divide the actual amount of medicine by five

29.925 g/5=5.985 g

Part d) Round the weight of one dose to the nearest gram

we have

5.985 g ------> 6 g

Answer:

45 less than twice a number is 5 times that number

Step-by-step explanation:

n = 15

Use one of the four fundamental arithmetic operations to add, subtract, multiply, or divide two or more integers. For challenging computations, we use the PEMDAS approach.

Given five times n is equals to 45 less than twice the number of n.

hence,

5 * n = 2* n + 45

3* n = 45

n = 15

Therefore the value of the n in the given problem is 15.

Answer:

x>-13/6

Step-by-step explanation:

First you multiply inside the bracket by -5 on left side. You get

-15x-20<6-3x

Then you place the like terms on same sides for which you add 3x to both side to get rid of 3x from right side and you add 20 to both sides to get ride of 20 from left side

-15x+3x<20+6

then you solve for x

-12x<26

x<-26/12

x> -13/6 (the inequality sign changes due to multiplication by a negative number)

Answer:  The correct option is

(A) [tex]\dfrac{1}{9}.[/tex]

Step-by-step explanation:  Given that y is directly proportional to x, and y = 6 when x = 54.

We are to find the constant of proportionality.

According to the given information, we can write that

[tex]y\propto x\\\\\Rightarrow y=kx~~~~~~~~~~~[\textup{where k is the constant of proportionality}]\\\\\Rightarrow k=\dfrac{y}{x}~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

When y = 6 and x = 54, then from equation (i), we get

[tex]\dfrac{6}{54}=k\\\\\Rightarrow k=\dfrac{1}{9}.[/tex]

Thus, the required value of the constant of proportionality is [tex]\dfrac{1}{9}.[/tex]

Step-by-step explanation:

Final answer:

The constant of proportionality for dollars earned per hour worked is 6.25, and the constant of proportionality for hours worked per dollar earned is 0.16.

Explanation:

To find the constant of proportionality for dollars earned per hour worked, we can use the formula y = kx, where y is the amount earned and x is the number of hours worked. Given that Lucy earned $25 for 4 hours of work, we can substitute these values into the equation:

25 = k * 4

Solving for k, we divide 25 by 4:

k = 25 / 4 = 6.25

Therefore, the constant of proportionality for dollars earned per hour worked is 6.25.

To find the constant of proportionality for hours worked per dollar earned, we can rearrange the equation to x = my, where x is the number of hours worked and y is the amount earned. Substituting the values, we get:

4 = m * 25

Solving for m, we divide 4 by 25:

m = 4 / 25 = 0.16

Therefore, the constant of proportionality for hours worked per dollar earned is 0.16.

Answer:

10/7

Step-by-step explanation:

Step 1: Subtract 12x from both sides.

−2x+5−12x=12x−15−12x

−14x+5=−15

Step 2: Subtract 5 from both sides.

−14x+5−5=−15−5

−14x=−20

Step 3: Divide both sides by -14.

−14x/14=−20/14

x=10/7

You get 10 over 7 because you simplify 20 over 14 by dividing them by 2 which would give you 10/7.

1. Expression 1: [tex]\((3x^2 - 6x + 11) \cdot (10x^2 - 4x + 6)\)[/tex]:[tex]\[30x^4 - 72x^3 + 34x^2 - 44x + 66\][/tex]

2. Expression 2: [tex]\((-3x^2 - 5x + 3) \cdot (-10x^2 - 7x + c)\)[/tex]:[tex]\(30x^4 + 71x^3 + 5x^2 - 21x + 3c\).[/tex]

3. Expression 3: [tex]\((12x^2 + 6x - 5) \cdot (5x^2 + 8x - 12)\)[/tex]: [tex]\(60x^4 + 126x^3 + 53x^2 + 40x - 60\).[/tex]

the expressions step by step:

1. Expression 1: [tex]\((3x^2 - 6x + 11) \cdot (10x^2 - 4x + 6)\)[/tex]

  To multiply these two expressions, we'll use the distributive property (also known as the FOIL method). Multiply each term in the first expression by each term in the second expression and then combine like terms.

  - Multiply the first terms: [tex]\(3x^2 \cdot 10x^2 = 30x^4\)[/tex]

  - Multiply the outer terms: [tex]\(3x^2 \cdot (-4x) = -12x^3\)[/tex]

  - Multiply the inner terms: [tex]\((-6x) \cdot 10x^2 = -60x^3\)[/tex]

  - Multiply the last terms: [tex]\((-6x) \cdot (-4x) = 24x^[/tex]2\)

  Now add up all the results:

  [tex]\[30x^4 - 12x^3 - 60x^3 + 24x^2 + 11 \cdot 10x^2 - 11 \cdot 4x + 11 \cdot 6\][/tex]

  Combine like terms:

[tex]\[30x^4 - 72x^3 + 34x^2 - 44x + 66\][/tex]

So, the equivalent expression is:[tex]\(30x^4 - 72x^3 + 34x^2 - 44x + 66\)[/tex].

2. Expression 2: [tex]\((-3x^2 - 5x + 3) \cdot (-10x^2 - 7x + c)\)[/tex]

  Follow the same steps as above to multiply the expressions:

  - Multiply the first terms: [tex]\((-3x^2) \cdot (-10x^2) = 30x^4\)[/tex]

  - Multiply the outer terms: [tex]\((-3x^2) \cdot (-7x) = 21x^3\)[/tex]

  - Multiply the inner terms: [tex]\((-5x) \cdot (-10x^2) = 50x^3\)[/tex]

  - Multiply the last terms: [tex]\((-5x) \cdot (-7x) = 35x^2\)[/tex]

  Combine the results:

[tex]\[30x^4 + 21x^3 + 50x^3 + 35x^2 + 3 \cdot (-10x^2) + 3 \cdot (-7x) + 3c\][/tex]

  Combine like terms:

[tex]\[30x^4 + 71x^3 + 35x^2 - 30x^2 - 21x + 3c\][/tex]

  Simplify further:

[tex]\[30x^4 + 71x^3 + 5x^2 - 21x + 3c\][/tex]

  So, the equivalent expression is: [tex]\(30x^4 + 71x^3 + 5x^2 - 21x + 3c\).[/tex]

3. Expression 3: [tex]\((12x^2 + 6x - 5) \cdot (5x^2 + 8x - 12)\)[/tex]

  Apply the same process:

  - Multiply the first terms:[tex]\(12x^2 \cdot 5x^2 = 60x^4\)[/tex]

  - Multiply the outer terms: [tex]\(12x^2 \cdot 8x = 96x^3\)[/tex]

  - Multiply the inner terms:[tex]\(6x \cdot 5x^2 = 30x^3\)[/tex]

  - Multiply the last terms:[tex]\(6x \cdot 8x = 48x^2\)[/tex]

  Combine the results:

  [tex]\[60x^4 + 96x^3 + 30x^3 + 48x^2 + 5 \cdot 5x^2 + 5 \cdot 8x - 5 \cdot 12\][/tex]

  Combine like terms:

  [tex]\[60x^4 + 126x^3 + 53x^2 + 40x - 60\][/tex]

  The equivalent expression is: [tex]\(60x^4 + 126x^3 + 53x^2 + 40x - 60\).[/tex]

Answer: The answers C

Step-by-step explanation: Use Desmos to find it

Answer:

Option C.

Step-by-step explanation:

If a line passes through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], then the equation of line is

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

From the given graph it is clear that the related line passes thorough the points (0,2.5) and (2,-1.5).

The equation of related line is

[tex]y-2.5=\frac{-1.5-2.5}{2-0}(x-0)[/tex]

[tex]y-2.5=\frac{-4}{2}(x)[/tex]

[tex]y-2.5=-2x[/tex]

Add 2.5 on both sides.

[tex]y-2.5+2.5=-2x+2.5[/tex]

[tex]y=-2x+2.5[/tex]

Th sign of inequality is either ≤ or ≥ because the related line is a solid line. It means the points on the line are included in the solution set.

Let the required inequality is

[tex]y\geq -2x+2.5[/tex]

(1,1) is included in the shaded region. So, the above inequality is true for (1,1).

[tex]1\geq -2(1)+2.5[/tex]

[tex]1\geq 0.5[/tex]

The assumed inequality is true for (1,1). So, the required inequality isn [tex]y\geq -2x+2.5[/tex].

Therefore, the correct option is C.
