Answer:
(2) The motorcycle cost $12,000 when purchased.
Step-by-step explanation:
In the standard exponential equation, y = ab^x, a is the original value.
Since the equation is V(t) = 12,000(0.75)^t, a is 12,000.
This means that the original value was 12,000.
So, the motorcycle cost $12,000 when it was first purchased.
The correct answer is (2) The motorcycle cost $12,000 when purchased.
Dentro de 15 años la edad de Carlos será el doble de la edad de Ana. Hace 6 años la edad de Carlos era el triple de la de Ana. Calcular la suma de sus edades y dar como respuesta la suma de cifras de este resultado
Answer:
Ana tiene 27 años mientras que Carlos, tiene 69 años
La suma de las edades es: 27+69 = 96
La suma de las cifras de este resultado es 9+6 = 15
Step-by-step explanation:
Vamos a hacer una linea temporal para ubicarnos en tiempo.
AÑO 2021, Ana tiene una edad A mientras que Carlos tiene una edad C
15 años para adelante
AÑO 2036, la edad de Carlos es el doble de la de Ana
C = 2A
Si nos vamos 6 años para atrás
AÑO 2015, la edad de Carlos es el triple de la de Ana
C = 3A
Como de 2015 a 2036 pasan 21 años, podemos plantear que
La edad de Carlos + 21 va a ser 2 veces la edad de Ana, traducido:
C + 21 = 2A, pero en 2015, ya sabemos que la edad de Carlos es el triple de la de Ana, entonces:
3A + 21 = 2A. Si despejamos:
3A - 2A = -21
A = |21| Ésta es la edad de Ana. (Ponemos valor absoluto porque una edad no puede ir negativa.
Si Ana en 2014 tiene 21 años, Carlos tiene 63 (el triple) por lo que sumamos 6 años y llegamos al presente:
En 2021, Ana tiene 27 años (21+6), mientras que Carlos tiene 69 (63+6). Edades actuales.
Nos corremos 15 años al futuro, por lo que llegamos al año 2036.
Carlos pasa a tener 84 años (69+15) y Ana, 42 (27+15) donde verificamos que la edad de Carlos, es el doble que la de Ana, 84/42 = 2.
Finalmente la suma de las edades es: 27+69 = 96
La suma de las cifras de este resultado es 9+6 = 15

The area of a kite is 120cm2. The length of one diagonal is 20cm. What is the length of the other diagonal?
Answer:
12cm
Step-by-step explanation:
The area of a kite is the product of the diagonals divided by 2:
A = (d1 * d2)/2
You can substitute what we have:
120 = (20 * d2)/2
And solve.
240 = 20 * d2
d2 = 12cm
The length of the other diagonal is 12cm.
What is area ?Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.
here, we have,
SOLUTION:
Step 1:
In this question, we are given the following:
The area of a kite is 120. One of the diagonals is 20.
What is the length of the other diagonal?
Step 2:
The details of the solution are as follows:
we know that,
The area of a kite is the product of the diagonals divided by 2:
A = (d1 * d2)/2
You can substitute what we have:
120 = (20 * d2)/2
And solve.
240 = 20 * d2
d2 = 12cm
CONCLUSION:
The length of the other diagonal = 12 cm.

Find the missing value for the parallelogram
Answer:
y = 85°
z = 35°
x = 60°
Step-by-step explanation:
y) 180 - 120 = 60, therefore:
180 - (35 + 60)
=> y = 85
z)
=> z = 35
x)
180 - (35 + 85)
=> x = 60
Hope this helps!
Answer:
to find y
you find the bottom right angle
which is 180-120 = 60
then you do 60+35 = 95
then 180 -95 because the sum of all angles in a triangle is 180
so the answer is 85 = y
There is a rule where the alternate angles between the parallel lines are identical
if y = 85 that means that the angle next to 35 is 85
same for angle z, if the top right 35, that means that angle z = 35
Now you add 35 + 85 = 120
180 - 120 = 60 = angle x
In summary
x=60
y=85
z=35
Hope that answers your question

Answer:
c) 152
Step-by-step explanation:
A central angle is equal to the measure of its corresponding arc.
∠AOB is a central angle and arc AB is its corresponding arc
Thus, ∠AOB ≅ Arc AB
Which means that because arc AB = 152, ∠AOB also equals 152
Given AB CD find the value of X

Answer:
x=60
Step-by-step explanation:
there is a law that says that the 124 angle and the unknown equation are equal, i just dont remember what that law is. but you can create the equation 124=2x+4 to solve for x, subtract 4 over and now you have 120=2x, divide by 2 and you will finish with 60=x

In an enclosure, there are 8 yellow chicks and 6 black and white chicks. The door opens and two chicks escape. What is the probability that both chicks were yellow?
Answer:4/13
Step-by-step explanation:
Number of yellow chicks = 8
Number of black and white chicks = 6
Total number of chicks = 8+6 = 14
The probability of the first yellow chick escaping will be 8 out of 14.
The probability of the second yellow chick escaping will be 7 out of 13 since there'll be 13 chicks left after the first yellow excaped.
Therefore, the probability that both chicks were yellow will be:
= 8/14 × 7/13
= 4/7 × 7/13
= 4/13
Therefore, the probability is 4/13.
estimate 63.730+ 32.73 by first rounding each number to the nearest whole number
Answer:
97
Step-by-step explanation:
Round each number to the nearest whole number (the digit directly left to the decimal point.) Note that if the digit to the right of the decimal point is 5 or greater, round up; if it is 4 or lower, round down:
63.730 rounded to the nearest one is 64.
32.73 rounded to the nearest one is 33.
Add:
64 + 33 = 97
97 is your answer.

4) In A ABC, m B = 25°, b = 12 and c = 21. Find all possible m2 C to the
nearest degree.
Answer:
47.7° or 132.3°
Step-by-step explanation:
In A ABC, m B = 25°, b = 12 and c = 21. Find all possible mC to the
nearest degree.
We solve the above question using Laws of sines.
The formula is given as
b/sin B = c/sin C
b = 12
B = 25°
c = 21
C = ?
Hence:
12/sin 25 = 21/sin C
Cross Mulitiply
= 12 × sin C = sin 25 × 21
sin C = sin 25 × 21/12
C = arc sin (sin 25 × 21/12)
C = 47.7°
The second possible value of C =
180° - 47.7°
= 132.3°
Therefore, all the possible values of mC = 47.7° or 132.3°

Roberta invested $600 $ 600 into a mutual fund that paid 4% 4 % interest each year compounded annually. Write an exponential function of the form =() y = a ( b ) x to describe the value of the mutual fund then use that function to determine the value of the mutual fund in 15 15 years.
Answer:
600 X (1.04)^15
$1080.57
Step-by-step explanation:
The formula for calculating future value:
FV = P (1 + r) n
FV = Future value
P = Present value
R = interest rate
N = number of years
600 X (1.04)^15 = $1080.57

Use the fraction strips to compare 2/4 and 5/8. use the drop-down menus to explain your comparison.
Comparing 2/4 and 5/8 is the same as comparing the length of ____ of the 1/4 sections and _____ of the 1/8 sections.
The sections of 2/4 is _____ the length of 5/8. Therefore, 2/4 < 5/8.
Answer:
[tex]\frac{2}{4} = 2 *\frac{1}{4} \\[/tex]
So the length of 2 of the 1/4 sections.
[tex]\frac{5}{8} = 5* \frac{1}{8}[/tex]
So the length of 5 of the 1/8 sections.
Now,
[tex]\frac{2}{4} = x *\frac{5}{8}\\\\x = \frac{2}{4} * \frac{8}{5} = \frac{16}{20} = \frac{4}{5}[/tex]
Therefore 2/4 is 4/5 the length of 5/8.
