Calcula la longitud en YARDAS de
un trayecto A que mide 100 metros
y la longitud en
YARDAS de un trayecto B que mide 18.50
Answer:
Las longitudes solicitadas en yardas son:
Trayecto A = 109.361 yardas.Trayecto B = 20.231785 yardas.Step-by-step explanation:
Para hacer la conversión de unidades que requieres en el ejercicio, debes saber que:
1 metro = 1.09361 yardasCon ese factor de conversión tú puedes hacer reglas de tres para calcular las medidas que requieres. En el caso del trayecto A:
Si:
1 metro = 1.09361 yardas100 metros = XEntonces:
[tex]x=\frac{100m *1.09361yardas}{1m}[/tex]Cancelamos metros y obtenemos:
x = 100 * 1.09361 yardasx = 109.361 yardasEn este caso, el trayecto A en yardas corresponde a 109.361 yardas. El mismo procedimiento puede aplicarse para el trayecto B:
Si:
1 metro = 1.09361 yardas18.50 metros = XEntonces:
[tex]x = \frac{18.50m*1.09361yardas}{1m}[/tex]Cuando se cancelan los metros se obtiene:
x = 18.50 * 1.09361 yardasx = 20.231785 yardasAsí, el trayecto B en yardas corresponde a 20.231785 yardas.

Answer:
19/20 is the correct answer
Answer:
19/20 quart
Step-by-step explanation:
the denominator should be the same so find some thing that is common to 4 and 5 so 20 and find what 4 in to 20 go 5 times so multiply 5×3=15 and 4×1=4 so add them together 15+4 = 19 so put 19 and 20 together equal 19/20

Step-by-step explanation:
A $40,000 car depreciates in value about 18% per year for the life of the car. Determine the value of the car after 7,8, and 9 years. What is the rate of decay?
Answer:
Value after:
7 years = $9971.42
8 years = $8176.56
9 years = $6704.78
Rate of decay = 18%
Step-by-step explanation:
A $40,000 car depreciates in value about 18% per year for the life of the car.
Determine the value of the car after 7,8, and 9 years. What is the rate of decay?
The formula for Depreciation is
FV = PV( 1 - r)^t
Where
FV = Future value
PV = Present value = $40,000
r = Depreciation rate = 18% = 0.18
t = time in years
a) After 7 years
$40,000 (1 - 0.18)⁷
= $9971.4188227
= $9971.42
b) After 8 years
$40,000 (1 - 0.18)⁸
= $8176.5634346
= $8176.56
c) After 9 years
$40,000 (1 - 0.18)⁹
= $6704.7820164
≈ $6704.78
= $9971.42
The Rate of decay = 18%
y = x + 2
y = 2x - 5
what is x and y
Answer:
x= 7 y= 9 (7,9)
Step-by-step explanation:
solve by using system if equations. multiply top answer by 2, giving u 2y=2x+4 and y=2x-5 subtract the equations. y=9 (the x cancels out) then put 9 in for y. 9=x+2. subtract 2. giving u 7. and now x =7

X, Y and Z are three points on a map. Y is 75km and on a bearing of 200° from X. Z is on a bearing of 150°, from Y. Z is due south of X. Calculate the distance between X and Z rounded to 1 DP.
Answer:
The distance between X and Z is approximately 114.9 km
Step-by-step explanation:
The given parameters are;
The distance of Y from X = 75 km
The bearing of Y from X = 200°
The bearing of Z from Y = 150°
The bearing of Z from X = 180°
In triangle XYZ, we have;
∠YZX = 180° - (130° + 20°) = 30°
By sine rule, we have;
(75 km)/sin(30°) = XZ/(sin(130°))
XZ = sin(130°) × (75 km)/sin(30°) ≈ 114.9 km
The distance between X and Z ≈ 114.9 km. to one decimal place.

A school has 320 girls and 250 boys the probability of a girl being left handed is 0.2 the probability of a boy being left handed is 0.1 estimate the amount of left handed people there are in the school
320 girls & 250 boys
0.2 probability 0.1 probability
320 x 0.2 = 64
250 x 0.1 = 25
64 + 25 = 89
There are approximately 89 students in the school that are left-handed.
Answer
89% of the people are left handed
Step-by-Step Explanation
To find this you have to first do 320 x 0.2
320 x 0.2= 64
To find it for boys you have to do 250 x 0.1.
250 x 0.1= 25
SO, the answer is 89%. 64% of girls and 25% of boys
