Suppose you loan $320 to a friend and charge them 11% annual interest. If they don't pay any back, how many years will it take for them to owe you $2,000? Round your answer to the nearest hundredth (2 places after the decimal).
Step-by-step explanation:
For them to owe you a total of$2000 then an interest of $2000-320=$1680 must have accrued over the time T
T=$1680×100/320×11
T=47.7272...≈47.73 to the nearest hundredth
Proof,
Interest after 47.7262...years which is converted to 525/11 years
=($320×11×525/11)/100
=$1680
therefore total amount which will be owed at that time =principal+interest accrued
=$320+1680=$2000

Step-by-step explanation:
A pickup truck carrying 10 to the power of 3 identical brick weighs 6770 pounds. If the empty truck weighs 6133 pounds, what is the weight of each brick?
Answer:
0.637 pounds per brick
Step-by-step explanation:
Given that:
A pickup truck carrying:
10³ identical brick weighs 6770 pounds
If the empty truck weighs 6133 pounds
The weight of each brick can be calculated as follows:
The weight of each brick = The weight of the full pick up truck - the weight of the empty truck
The weight of each brick = 6770 - 6133
The weight of each brick = 637
The pickup truck carrying 10³ identical brick = 1000 identical brick
Thus, the weight of each brick = 637/10³
Thus, the weight of each brick = 0.637 pounds per brick

Stephanie wants to find out how much a visit to an amusement park will cost her. The amusement park charges a $20 admission fee, as well as $0.50 for each ride, r. The expression 0.50r + 20 represents this situation. Evaluate this expression when r = 15. Explain what this value means in terms of the context of Stephanie's visit to the amusement park.
Answer:
Step-by-step explanation:
0.50(15)+20=x
7.50+20=x
27.5=x
Therefore, x means how much the visit to the amusement park will cost her.

2. First he sold half so but we dont know the starting number so we put x/2 then we have to add 6 and we get 16
I need help with the range
Answer:
[-9, 0]
Step-by-step explanation:
The range is the y values that the equation/line covers.
The line's lowest point is -9 and the line's highest point is 0. The values are defined (no open circle at the highest point) so we use brackets.
Nathan is planning to ride his bike for 24 minutes. If he rides at a rate of 3 miles per hour, how far will he travel?
Answer:
1.2 miles in 24 minutes
Step-by-step explanation:
3 miles per hour = .05 miles per minute
24 x 0.05 = 1.2
Remember that speed is defined as the rate of change of the position respect to the time, thus we can define the relation:
Distance = Spee*Time.
Using this we will get the solution: distance = 1.2 miles
Let's see how to get the solution:
We start with the given information:
Nathan rides for 24 minutes.His speed is 3 miles per hour.So we got a time and we also have a speed, but the time units in these are different.
So knowing that:
1 hour = 60 minutes
(1 hour/60 minutes) = 1
Then we can write:
24 minutes = (24 minutes)*(1 hour/60 minutes) = 0.4 hours
Then we have:
time = 0.4 hours
speed = 3 miles per hour.
Then, using the first equation, we get:
distance = (3 miles per hour)*0.4 hours = 1.2 miles.

The power, P (watts), of a car engine is proportional to the square of its speed, s(m/s) When s= 30 P= 1500 Work out the speed (to 1 DP) when the power is 1715 watts
Answer:
S = 32.1 m/s
Step-by-step explanation:
P = 1,500
S = 30
since P is proportional to S², then we must first determine S² = 900
900 / 1,500 = S² / 1,715
(900 x 1,715) / 1,500 = S²
1,543,500 / 1,500 = S²
S² = 1,029
S = √1,029 = 32.08 m/s ≈ 32.1 m/s
At the Atlanta United game, a ball flew into the stands. A fan launches the ball at 19.6 feet per second (ft/s) from a 60 ft tall bleacher. The equation for the soccer ball's height, s, at time, t, seconds after the launch is s(t) = −4.9t2 + 19.6t +60. When does the ball hit the ground?
Answer:
6.03s
Step-by-step explanation:
Given the equation for the soccer ball's height, s, at time, t, seconds after the launch expressed as
s(t) = −4.9t2 + 19.6t +60
The ball hits the ground when s(t) = 0
Substitute s(t) = 0 into the expression
0= −4.9t2 + 19.6t +60
Multiply through by -10
0 = 49t²-196t-600
49t²-196t-600 = 0
Factorize
t = 196±√196²+4(600)(49)/2(49)
t = 196±√38416+117600/98
t = 196±√156016/98
t =196±394.99/98
t = 196+394.99/98
t = 590.99/98
t = 6.03secs
Hence the ball bit the ground after 6.03seconds later

How do I solve 4x+23>-21
Answer:
Inequality Form:
x>-11
Step-by-step explanation:
Interval Notation:
(-11,\infty )
Answer:
Step-by-step explanation:
4x + 23 > -21
4x > -21 -23 (moving 23 to the right side of equation changes the +23 to -23
4x > -44 (adding -21 to -23)
x > -11 (dividing both sides of equation by 4, this keeps the equation the same
Solution: x > -11 (x is greater than negative 11)

Nicholas found the 13th term of the geometric sequence 15, 30, 60, 120 the following way:
A(13) = 15 * 213
A(13) = 15 * 8,192
A(13) = 122,880
Is Nicolas correct? Why or why not? (Make sure to justify your answer) If Nicolas is incorrect please state the correct solution.
Answer: No. Nicolas is wrong.
Step-by-step explanation:
The formula for calculating nth term of a geometric sequence is given as:
= ar^n-1.
where a = first term = 15
r = common ratio = 30/15 = 2
n = 13
Using the formula,
= ar^n-1
= 15 × 2^(13-1)
= 15 × 2^12
= 15 × 4096
= 61440
The 13th term is 61440. Nicolas is wrong.
