As a result of depreciation, the value of a car is now $19,200. This is four-fifths of its original value. Find the original value of the car. $
Answer:
The original value of the car is $24,000
Step-by-step explanation:
Here, we want to calculate the original value of the car
Let the original value of the car be $x
Now, 4/5 of this value is $19,200
Mathematically, we have it that;
4/5 * x = 19,200
4x = 5 * 19,200
x = (5 * 19,200)/4
x = $24,000
Find the value of x and y! Also their given relationship. Ty!
Answer:
x = 3, y = 30.4
Step-by-step explanation:
From the given diagram;
8x - 3 = 6x+3 (alternate exterior angle are equal)
Collect like terms
8x - 6x = 3 + 3
2x = 6
x = 6/2
x = 3
Also;
8x - 31 + 5y + 35 = 180 (sum of angle on a straight line is 180)
8(3) - 31 + 5y + 35 = 180
5y + 24 - 31 + 35 = 180
5y + 28 = 180
5Y = 180 - 28
5Y = 152
y = 152/5
y = 30.4
Hence x = 3, y = 30.4

Answer:
sinA = 12/13, cosA = 5/13, tanA = 12/5
sinB = 5/13, cosB = 5/13, tanB = 5/12
Step-by-step explanation:
Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
Sin(A) = 12/13
Sin(B) = 5/13
Cos(A) = 5/13
Cos(B) = 12/13
Tan(A) = 12/5
Tan(B) = 5/12
A Ferris Wheel has a radius of 16 feet. How far will you travel if you take a ride that goes around 5 times? Round answer to the nearest hundredth and for pi use π = 22 7 .
Answer:
502.85 feet
Step-by-step explanation:
Given that,
The radius of a Ferris wheel, r = 16 feet
We need to find how far will you travel if you take a ride that goes around 5 times.
Distance = 5×2πr
So,
= 10πr
[tex]=10\times \dfrac{22}{7}\times 16\\\\=502.85\ \text{feet}[/tex]
So, the required distance is 502.85 feet.

Mr. Armstrong went to Target to buy four pairs of dress socks. There was a 30% off sale
on the socks, and his total bill before tax was $14. What was the price of each pair of socks
before the sale?
Answer: $5
Step-by-step explanation:
We should note that since there was a 30% off sale, it means that he paid for 70% (100% - 30%) of the sales price.
Therefore, let the price of the socks be represented as x.
70% of x = 14
70/100 × x = 14
0.7 × x = 14
0.7x = 14
x = 14 / 0.7
x = 20
Therefore, the price of the socks was $20. Since there are 4 pairs, each pair will be:
= $20 / 4
= $5

The slope of the line below is -3.
Answer:
D. y + 7 = -3(x - 5)
Step-by-step explanation:
Point-slope form: y - y₁ = m(x - x₁)
⇒ y - (-7) = -3(x - 5)
⇒ y + 7 = -3(x - 5)
Answer:
B. y + 7 = 3(x - 5).
Step-by-step explanation:
y -y1 = m(x - x1)
y - (-7) = 3(x - 5)
y + 7 = 3(x - 5).

A ball is thrown into the air with an upward velocity of 44 ft/s. It’s height h in feet after t seconds is given by the function h=-16t^2 +44t+5. How long does it take the ball to reach its maximum height? What is the balls maximum height?
9514 1404 393
Answer:
1.375 seconds35.25 feetStep-by-step explanation:
A quadratic function y=ax^2 +bx +c is symmetric about the vertical line x=-b/(2a). That is the x-coordinate of the vertex (maximum or minimum).
Here, we have ...
h = -16t^2 +44t +5
t = -44/(2(-16)) = 11/8 = 1.375
It takes 1.375 seconds for the ball to reach its maximum height.
The height at that time is ...
h = (-16(11/8) +44)(11/8) +5 = (-22 +44)(11/8) +5 = 121/4 +5 = 141/4 = 35.25
The maximum height is 35.25 feet.

Answer:
y=36degrees
Step-by-step explanation:

2y=72
72/2
y=36degrees
Answer:
Step-by-step explanation:
Because these are supplementary angles they must have a sum of 180 degrees.
74+2y+34=180
2y+108=180
2y=72
y=36 degrees

Michelle has four credit cards with the balances and interest rates listed below. If Michelle wanted to pay off all four credit cards in 36 months, what would her total monthly credit card payment be? Credit Card Balance APR #1 $4,380 17% #2 $1,365 19% #3 $2,480 23% #4 $5,000 15% a. $367.36 b. $393.20 C. $475.67 d. $481.44
Answer:
c.
$475.67
Step-by-step explanation:
#4, #1, #3, #2
We will calculate the total amount for each of the credit card and then arrange them in descending order according to their interest after 36 months (3 years)
Interest on Credit card 1 =
= $2233
Interest on credit card 2 =
= $778
Interest on credit card 3 =
= $1656
Interest on credit card 4 =
= 2250
Hence the correct order to pay off all the credit card balances is
#4, #1, #3, #2
Her total monthly credit card payment will be $561.05.
Payment calculationGiven that Michelle has four credit cards with the balances and interest rates listed below, if Michelle wanted to pay off all four credit cards in 36 months, to determine what would her total monthly credit card payment be, calculate the total amount of each card of credit including interest, add all the amounts, and then divide the result by 36:
(4,380 x (1 + 0.17 x 3) + 1,365 x (1 + 0.19 x 3) + 2,480 x (1 + 0.23 x 3) + 5,000 x (1 + 0.15 x 3)) / 36 = X(4380 x 1.51 + 1365 x 1.57 + 2480 x 1.69 + 5000 x 1.45) / 36 = X(6613.8 + 2143.05 + 4191.2 + 7250) / 36 = X20198.05 / 36 = X561.05 = XTherefore, her total monthly credit card payment will be $561.05.

Given:
A figure of a triangle.
To find:
The values of x and y.
Solution:
From the given triangle it is clear that the base angles of the triangle are equal, so the triangle is an isosceles triangle.
Altitude on the base of the isosceles triangle from from the opposite angle is a median. It means, it divides the base in two equal parts.
In the given triangle, the altitude divides the base in two equal parts and the measure of each part is 9 units.
In a right triangle,
[tex]\cos \theta=\dfrac{Base}{Hypotenuse}[/tex]
[tex]\cos 60^circ=\dfrac{9}{y}[/tex]
[tex]\dfrac{1}{2}=\dfrac{9}{y}[/tex]
[tex]1\times y=9\times 2[/tex]
[tex]y=18[/tex]
And,
[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]
[tex]\tan 60^\circ=\dfrac{x}{9}[/tex]
[tex]\sqrt{3}=\dfrac{x}{9}[/tex]
[tex]9\sqrt{3}=x[/tex]
Therefore, the correct option is D.
