Answer:
Rita has three cousins.Step-by-step explanation:
We must reverse this operation in order to solve it.
First, add one cousin to 8.
8 + 1 = 9.
Then, divide 9 by 3.
9 / 3 = 3.
Rita has three cousins.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
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.

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

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
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.

What is the slope of (-3,-2) and (-1,-5)
Answer:
-3/2
Step-by-step explanation:
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
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.
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)

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.
