Answer:

C: Jordana made a mistake when she calculated the length of side B.

Step-by-step explanation:

Jordana made a mistake while calculating the length of side B.

A scale factor is a factor by which dimensions of an object are enlarged or diminished.

One parallel length i.e. side A of original isosceles trapezoid = 12cm

One parallel length  i.e. side A of reduced isosceles trapezoid =4cm

So, scale factor = 4/12 =1/3

Other parallel length i.e. side B of original isosceles trapezoid =

So, the other parallel length i.e. side B of reduced isosceles trapezoid = 36*1/3 = 12cm

The side lengths of the reduced isosceles trapezoid = 30*1/3 = 10cm

So, the perimeter of the reduced isosceles trapezoid =4+12+10+10 =36cm

While Jordana calculated the length of side B as 4.

Thus, Jordana made a mistake while calculating the length of side B.

Answer:

Measurement unit for F = (Nutrients • Moisture)/Pollutants.

Option C is correct

Step-by-step explanation:

From the question, we are given the formula; F = NM/P

where;

N is the amount of nutrients in the soil

M is the amount of moisture in the soil.

P is the amount of pollutants in the soil

From the definition of the terms above, the units of the can be expressed as;

N = nutrients

M = moisture

P = pollutants

Thus, the measurement unit for fertility is;

F = NM/P = (Nutrients • Moisture)/Pollutants

Answer:

6 hrs

Step-by-step explanation: If Im reading corectly your saying that Mrs. Perry is painting for 4 hours plus Mr. Chesah painting for 2 hours (half of 4 hours) Add them up and get 6 hrs.  I hope this is what you meant.

To find out how long it would take Mrs. Perry and Mr. Chesah to paint the office together, we can use the idea of work completion rate. When two people work together, their work completion rates are added. Therefore, if they work together, it would take them 1 hour and 20 minutes to paint the office.

To find out how long it would take Mrs. Perry and Mr. Chesah to paint the office together, we can use the idea of work completion rate. Let's say that Mrs. Perry can paint 1 office in 4 hours, which means her work completion rate is 1/4 offices per hour. Since Mr. Chesah can paint the same office in half the time, his work completion rate is 1/2 offices per hour.

When two people work together, their work completion rates are added. So, the combined work completion rate of Mrs. Perry and Mr. Chesah is 1/4 + 1/2 = 3/4 offices per hour.

To determine how long it would take them together to paint Perry's office, we can take the reciprocal of the combined work completion rate. This gives us 4/3 hours, which is equivalent to 1 hour and 20 minutes. Therefore, if they work together, it would take them 1 hour and 20 minutes to paint the office.

The common difference of the sequence is -7

Step-by-step explanation:

Because each time the the numbers are going down by minus 7

The common difference of this sequence is, - 7

And, One formula for the sequence is,

⇒ a (n) = 67 - 7n

And, The tenth term for this sequence is,

⇒ a (10) = - 3

An arithmetic sequence is the sequence of numbers where each consecutive numbers have same difference.

Given that;

The sequence is,

⇒ 60, 53, 46, 39, 32, 25, ...

Now, The common difference of this sequence is,

⇒ 53 - 60

⇒ - 7

And, One formula for the sequence is,

⇒ a (n) = a + (n - 1) d

⇒ a (n) = 60 + (n - 1) (- 7)

⇒ a (n) = 60 - 7n + 7

⇒ a (n) = 67 - 7n

And, The tenth term for this sequence is,

⇒ a (n) = 67 - 7n

⇒ a (10) = 67 - 7 x 10

⇒ a (10) = 67 - 70

⇒ a (10) = - 3

Thus, The common difference of this sequence is, - 7

And, One formula for the sequence is,

⇒ a (n) = 67 - 7n

And, The tenth term for this sequence is,

⇒ a (10) = - 3

Answer:

x=19

Step-by-step explanation:

The total angle in a straight line is 180 degrees.

To work this out you would first add 7 and 4 to -2, this gives you 9. Then you would minus 9 from 180, which gives you 171. This is because you are removing the extra numbers and so all you are left with is the x's. Then you would add 5x and x and 3x, which gives you 9x. Then you would divide 171 by 9, which gives you 19.

1) Add 7 and 4 and -2.

[tex]7+4+(-2)=9[/tex]

2) Minus 9 from 180.

[tex]180-9=171[/tex]

3) Add 5x and x and 3x.

[tex]5x+x+3x=9x[/tex]

4) Divide 171 by 9.

[tex]171/9=19[/tex]

5) [tex]x=19[/tex]

The sum of all the angles is 180 degrees because this is a supplementary angle.

5x + 4 + x - 2 + 3x + 7 = 180

Now you can combine like terms:

(5x + x + 3x) + (4 - 2 + 7) = 180

9x + 9 = 180

Now you must isolate x:

9x + 9 - 9 = 180 - 9

9x + 0 = 171

9x = 171

9x/9 = 171/9

x = 19

Check:

5(19) + 4 + 19 - 2 + 3(19) + 7

95 + 4 + 19 - 2 + 57 + 7

Answer:

  112°

Step-by-step explanation:

The law of cosines can be used to find angle C from the three side lengths. The usual formulation of that law is ...

  c^2 = a^2 + b^2 -2ab·cos(C)

Then the angle C can be found to be ...

  C = arccos((a^2 +b^2 -c^2)/(2ab))

For the given side lengths,

  C = arccos((40^2 +56^2 -80^2)/(2·40·56)) = arccos(-1664/4480)

  C ≈ 112°

Answer:

Step-by-step explanation:

Answer C (x + 1) is correct; if we let x + 1 equal 0, we get the root (x-intercept) -1, which appears on this graph

X + 1 must be a factor of the polynomial graphed

How to find the factor

The factor is solved using the points where the graph intersects the x-axis.

This points are called the roots

Examining the graph the roots are x = -1 and x = 4

Hence x + 1 must be a factor

Step-by-step explanation:

To determine the amount of the drug per dosage, we need to convert the weight of the person from pounds to kilograms and multiply it by the dosage of 21 mg per kg per day. Then, we divide the total amount by 2 to get the amount of the drug per dosage.

To determine the amount of the drug per dosage, we need to convert the weight of the person from pounds to kilograms. Since 1 kilogram is equal to 2.2 pounds, we can divide the weight in pounds by 2.2 to get the weight in kilograms. In this case, 181 pounds is approximately 82.27 kilograms.

Next, we multiply the weight in kilograms by the dosage of 21 mg per kg per day. This gives us the total amount of the drug needed per day. In this case, the total amount is approximately 1728.67 mg.

Since the drug is divided into two doses every 12 hours, we divide the total amount by 2 to get the amount of the drug per dosage. Each dosage should be approximately 864.34 mg.

Final answer:

To determine the amount of the drug that should be given each dosage, convert the weight from pounds to kilograms and multiply by the dosage of 21 mg per kg per day. The person should receive approximately 862.05 mg of the drug each dosage.

Explanation:

To determine the amount of the drug that should be given each dosage, we first need to convert the weight of the person from pounds to kilograms. 181 pounds is approximately equal to 82.10 kilograms. Next, we multiply the weight in kilograms by the dosage of 21 mg per kg per day. Thus, the person should receive approximately 1724.10 mg of the drug per day. Because the dosage is divided into two doses, they should receive approximately 862.05 mg of the drug each dosage.
