Jordana made a mistake when she calculated the length of side B.
Jordana did not make any mistakes in her work.
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.
What is a scale factor?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.

A new car is purchased for $ 41 , 000 $41,000 and over time its value depreciates by one half every 3 years. What is the value of the car 17 years after it was purchased, to the nearest hundred dollars?
Answer:
$800
Step-by-step explanation:
A = P [tex](0.5)^{t}[/tex]
Because it's every 3 years, you need to find how many 3 years in the 17-year-period of time.
17/3 = 5.666...
P is initial amount:
A = $41, 000 [tex](0.5)^{5.666...}[/tex]

An airplane flies from point A to point B. Point A is 40 kilometers from a ground signal at point C. Point
B is 56 kilometers from the same ground signal. If AB = 80 kilometers, find the measure of ACB to
the nearest degree.
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°

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

In order to increase by 4.1%, you must multiply whatever number you have by the decimal: 1.041.
Say the number we want to increase by 4.1% is x. Then:
x + (4.1%) * x = x(1 + 4.1%) = x(1 + 0.041) = 1.041x
So, you would multiply by 1.041.

A certain drug dosage calls for 21 mg per kg per day and is divided into two doses (1 every 12 hours). If a person weighs 181 pounds, how much of the drug should they get each dosage?
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.
Explanation: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.

Step-by-step explanation:
First we will find the volume of the square at the bottom
V = s^3 where s is the side length
V = 5^3
V = 125 in^3
Then we will find the volume of the rectangular prism at the top
V = l*w*h
V = 12*3*3
V =108 in^3
The total volume is the sum of the two volumes
V = 125+108

The value of x is_degrees
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
180
