B.2008
C.2010
D.2012
Answer:
Step-by-step explanation: 2012
Answer:
The second method is estimating the initial value of the car. Let's assume you were offered to buy a three-year-old car for $12,000. If you input the value into the "3 years" box, the car depreciation calculator will display the initial value of the car - in this case, over $20,500. You can now compare it to the price of a brand new car.

a) (-5±√10)/3 ≈ {-2.721, -0.613}
b) (6±√21)/5 ≈ {0.283, 2.117}
Step-by-step explanation:
a) The relevant coefficients are ...
a = 3, b = 10, c = 5
[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x=\dfrac{-10\pm\sqrt{10^2-4\cdot3\cdot5}}{2\cdot3}=\dfrac{-10\pm\sqrt{40}}{6}\\\\\boxed{x=\dfrac{-5\pm\sqrt{10}}{3}\approx\{-2.721, -0.613\}}[/tex]

Lindsey invests $1500 in one account and $900 in an account paying 4 % higher interest. At the end of one year she had earned $204 in interest. At what rates did she invest?
Answer: She invest 41500 at 7% interest and 900 at 11% interest.
Step-by-step explanation:
Formula for simple interest = [tex]\dfrac{\text{Principal x rate x Time}}{100}[/tex]
Let [tex]P_1=\$1500,\ P_2=\$900\ \ \ \ , r_1=r, \ \ r_2=r+4,\ \ \ t_1=t_2=1[/tex]
Simple interest by first investment = [tex]\dfrac{P_1r_1t_1}{100}=\dfrac{1500(r)(1)}{100}=15r[/tex]
Simple interest by second investment = [tex]\dfrac{P_2r_2t_2}{100}=\dfrac{900(r+4)(1)}{100}=9(r+4)[/tex]
As per given,
Total interest = $204
[tex]\Rightarrow 15r+9(r+4)=204\\\\\Rightarrow\ 15r+9r+36=204\\\\\Rightarrow\ 24r=204-36\\\\\Rightarrow\ 24r=168\\\\\Rightarrow\ r=\dfrac{168}{24}\\\\\Rightarrow\ r=7\%[/tex]
Hence, she invest 41500 at 7% interest and 900 at 11% interest.

Jenna has $30 in her bank account. She needs more than $250 to buy a new pair of sneakers. She is able to save $20 per week. Let w represent the number of weeks she saves. How many weeks will she need to save before she has enough money for the sneakers?
Answer:
30+20w=250
w=11
Step-by-step explanation:
To do this, write this equation because 30 is what she had and 20w is the weeks. We don't know the weeks so use w. Finally, put=250
30+20w=250
To solve this, do 250-30=220
So 20w=220
Divide 220/20
W=11
Answer:
11 weeks
Step-by-step explanation:
The equation would be 20w + 30 = 250
so, we need to solve w.
20w + 30 = 250
- 30 - 30
20w = 220
___ ____
20 20
w = 11

Answer:
Not proportional
Step-by-step explanation:
22/20 does not equal 18/15.
Answer:
B: Not proportional
Step-by-step explanation:
This wouldn't be proportional because for you, you are making 22 heartbeats in 20 seconds and 22-20 is 2. But if you look at your friend, he/she is doing 18 heartbeats in 15 seconds so add 5 so that 23 heartbeats is happening in 20 seconds and 23-20 is 3. If we compare, 3 is not the same as 2 making it not proportional.

A music player was marked down by 1/4 of the original price. If the sales price is $128, what is the original price? If the music player was marked up by ½ before it was placed on the sales floor, what was the price that the store paid for the player? What is the difference between the discount price and the price that the store paid for the music player?
Answer:
Step-by-step explanation:
Let the original price be represented by x.
1. [tex]\frac{1}{4}[/tex] of x = x - 128
[tex]\frac{x}{4}[/tex] = x - 128
x - [tex]\frac{x}{4}[/tex] = 128
4x - x = 4 x 128
3x = 512
x = [tex]\frac{512}{3}[/tex]
= 170.67
x = 170.67
The original price is $170.67.
2. If the price of the music player was marked up by ½ of its original price, its new price would be;
170.67 + (170.67 x ½) = 170.67 +85.335
= 256.005
≅ $ 256.0
The price paid by the store for the music player is still the original price i.e $170.67.
3. The difference between the discounted price and the price paid by the store can be determined by;
price paid by the store - the discounted price of the music player
= $170.67 - $128
= $42.67
A red-tailed hawk dives at a constant rate in which its altitude changes by -7 ½ meters in 0.15 seconds. How long will it take the hawk to dive -70 meters?
Answer:
1.4 seconds
Step-by-step explanation:
If the red-tailed hawk dives at a constant rate in which its altitude changes by -7 ½ meters in 0.15 seconds, the rate at which it changes its altitude is thus -7 ½ meters ÷ 0.15 seconds = -7.5 meters ÷ 0.15 seconds = -50 meters per second = -50 m/s.
Now, If the red-tailed hawk dives to a depth of -70 meters, the time it will take to cover that distance is t = distance/rate = -70 m/-50 m/s = 7/5 s = 1.4 s
So, it will take the red-tailed hawk 1.4 seconds to dive to a distance of -70 meters.
If ABC=DEC, C=55, D=65, and B=2x. x=?
Answer:
X = 30
Step-by-step explanation:
B = E
DEC = 180 degrees/ 65 + E + 55 = 180
E = 60
B = 2x
2x = 60
x = 30
The value of x in the given figure is 32.5.
What is a triangle?It is a two-dimensional figure which has three sides and the sum of the three angles is equal to 180 degrees.
We have,
∠C = 55
∠D = 65
∠B = 2x
∠D and ∠B are alternate angles.
Alternate angles are equal.
65 = 2x
x = 65/2
x = 32.5
Thus,
The value of x is 32.5

Answer:
Choices C and D
Step-by-step explanation:
The most simplest way is just to solve each one and see which two have the same answer as the first expression.
But you could also see that both of the [tex]\frac{4}{7}[/tex] are going to cancel each other out so you are left with [tex]-\frac{8}{9} +\frac{9}{8}[/tex] which is also choice C.
For choice D I distributed the negative one to the insides of the parenthesis that left me with [tex]-\frac{4}{7}-\frac{8}{9}+\frac{4}{7} +\frac{9}{8}[/tex] which is the same expression as the first one.

paid a $25.90 setup fee and $8.15 per shirt to have the shirts made. How many shirts do they need to sell to break even?
If x represents the number of shirts, write an equation to represent the situation.
Write an equation
Answer:2 I think?
Step-by-step explanation:
The required expression for the shirts they need to sell to break even is y = 25.90 + 8.15x.
Given that,
T-shirts made for homecoming that they plan to sell for $10 each.
They paid a $25.90 setup fee and $8.15 per shirt to have the shirts made.
How many shirts do they need to sell to break even is to be determined?
The equation is the relationship between variables and represented as y =ax +b is an example of a polynomial equation.
Let, x represents the number of shirts and y be the total cost for the number of x shirts,
They paid a $25.90 setup fee and $8.15 per shirt to have the shirts made.
Implies,
The total cost of x shirts = $8.15x
Total spend on the manufacturing of x shirts,
y = $25.90 + 8.15x
Thus, the required expression for the shirts they need to sell to break even is y = 25.90 + 8.15x.

LeeAnn is bringing her sick cat Snowball in for a series of appointments at the veterinary clinic. Her total cost over the course of treatment will be $250 for tests and medicine plus $45 per appointment, a. Part A Write an equation to show the total cost, t, she will owe. Part B The clinic offers LeeAnn a 25% discount off of her total cost. Write an equation to show her updated cost. Part C What will be LeeAnn's total discounted cost of Snowball's treatment requires six veterinary appointments? Form B Show your work.
Answer:
Part A: y = $250 + $45x
Part B: U = y * 0.75 or U = ($250 + $45x) * 0.75
Part C: $390
Step-by-step explanation:
Part A: In this scenario, we have fixed costs for the treatment and two variables, one of which is the number of appointments which is represented by the letter x and the total amount of costs which is represented by the letter y in the following equation...
y = $250 + $45x
Part B: Now we have the equation for the total cost we can update it to add the 25% discount. Since this is a discount it means that it is being subtracted from the 100% original price. Therefore, we need to multiply the total cost by the decimal form of 75% (100 - 25) which we can get by dividing the percentage by 100 like, which gives us 0.75. Now we multiply this value by the total cost in order to get the updated cost (U).
U = y * 0.75 or U = ($250 + $45x) * 0.75
Part C: Now we can substitute the number of appointments variable (x) by 6 and solve for U.
U = ($250 + $45x) * 0.75
U = ($250 + $45(6)) * 0.75
U = ($250 + $270) * 0.75
U = $520 * 0.75
U = $390
