At a horseback riding competition in the Olympics, each rider receives a score from 2 judges’
scores. Maddy was one of the riders in the competition. If one judge awarded Maddy a score
of 87, and Maddy’s final score was 84.5, what score did the other judge award Maddy?
Answers
Answer: 82
Step-by-step explanation:
Let the score that the other judge gave Maddy be M
We get the equation
(87+M)/2 = 84.5

A science test, which is worth 100 points, consists of 24 questions. Each question is worth either 3 points or 5 points. If x is the number of 3-point questions and y is the number of 5-point questions, the system shown represents this situation.
x + y = 24
3x + 5y = 100
What does the solution of this system indicate about the questions on the test?
The test contains 4 three-point questions and 20 five-point questions.
The test contains 10 three-point questions and 14 five-point questions.
The test contains 14 three-point questions and 10 five-point questions.
The test contains 20 three-point questions and 8 five-point questions.
Answers
Answer:
10 three-point questions and 14 five-point questions.
Step-by-step explanation:
x+y = 24
3x+5y = 100
We can solve this system of equations using elimination. In order to do this, let's first multiply the first equation by 3...
3x+3y=72
3x+5y=100
Now, subtract the first equation from the second equation...
2y=28
Divide both sides by 2
y=14
Plug this back into any of the equations to solve for x...
x+14=24
x=10

James is trying to save money for college. When
he is 5 years old, his uncle puts $750 into a
savings account for him. The money should
increase by 5% each year until he needs it for
college.
Write an exponential model for this situation.
Answers
Answer:
[tex]y=(750)1.05^t[/tex], where [tex]t[/tex] is the time (in years) from investment
Or [tex]y=(750)1.05^{t-5}[/tex], where [tex]t[/tex] is the age of James
Step-by-step explanation:
exponential model: [tex]y=ab^t[/tex], where [tex]t[/tex] is the time (in years) from investment
when t = 0, y = 750
[tex]\implies 750=ab^0[/tex]
As [tex]b^0=1[/tex]
[tex]\implies 750=a[/tex]
Therefore, [tex]y=750b^t[/tex]
If the savings increase by 5% each year, then b = 105%.
105% = 105/100 = 1.05
Therefore, b = 1.05
So final model: [tex]y=(750)1.05^t[/tex], where [tex]t[/tex] is the time (in years) from investment
Or, we can write this as [tex]y=(750)1.05^{t-5}[/tex], where [tex]t[/tex] is the age of James

Nancy mistakenly measured the temperature of a heated liquid to be 48°C. The actual
temperature of the headed liquid was 50°C. What was the percent error?
Answers
Answer:
4.17% (nearest hundredth)
Step-by-step explanation:
percent change = [ (difference between initial value and final value) ÷ initial value] x 100

Determine the slope and the y-intercept of the following equation.
2x + 7y = 8
Answers
Answer:
the slope = -2/7
the y-intercept = 8/7
Step-by-step explanation:
Rewrite the equation to a slope-intercept form:
7y = 8 - 2x
7y = -2x + 8
[tex]y=-\frac{2}{7}x+\frac{8}{7}[/tex]
so the slope = -2/7
the y-intercept = 8/7

If 9x + 12 = 48 what is x-10?
Answers
Answer:
x - 10 = -6
Step-by-step explanation:
9x + 12 = 48
Subtract 12 from both sides.
9x + 12 = 48
- 12 - 12
+ 12 and - 12 cancel out. 48 - 12 is 36.
9x = 36
Divide 9 from both sides.
9x = 36
÷ 9 ÷ 9
9 ÷ 9 cancels out. x is left. 36 ÷ 9 is 4.
x = 4
Knowing x = 4, solve the equation.
x - 10 = ?
Plug in 4.
4 - 10 = -6
4 - 10 equals -6. This is your answer.
Hope this helped!
Answer:
i)
9x + 12 = 48
or,9x=48-12
or,9x=36
or,x=36/9

What’s the length of this missing leg?
Answers
Answer:
b = 4.5 mm
Step-by-step explanation:
using Pythagoras theorem:
a² + b² = c²
4² + b² = 6²
b² = 6² - 4²
b² = 36 - 16
b² = 20
b = √20
b = 4.5
Pythagoras theorem:
a² + b² = c²
4² + b² = 6²
b² = 6² - 4²
b² = 36 - 16
b² = 20
b = [tex] \sqrt{20}[/tex]

Some people attended a small concert last Saturday. 70 of those people sat in the balcony
of the theater. This was 35% of the people who attended. How many people were at the
concert?
Answers
Answer:
200
Step-by-step explanation:
If 'a' is the total attendance, the given relation is ...
70 = 0.35a . . . . . . 70 is 35% of attendance
Dividing by the coefficient of 'a', we find the attendance was ...
70/0.35 = a = 200
200 people were at the concert.
Stringed instruments like guitars and pianos create a note when a string vibrates back and forth. The distance that the middle of the string moves from the center is called the amplitude (a), and for a guitar, it starts at 0.75 mm when a note is first struck. Amplitude decays at a rate that depends on the individual instrument and the note, but a decay rate of about 25% per second is typical. Calculate the time it takes for an amplitude of 0.75 mm to reach 0.1 mm.
The amplitude will reach 0.1 mm in about 7 seconds.
The amplitude will reach 0.1 mm in about 7 seconds.
The amplitude will reach 0.1 mm in about 15 seconds.
The amplitude will reach 0.1 mm in about 15 seconds.
The amplitude will reach 0.1 mm in about 1.5 seconds.
The amplitude will reach 0.1 mm in about 1.5 seconds.
The amplitude will reach 0.1 mm in about 3 seconds.
Answers
The the product of the initial amplitude and the exponential decay rate
of raised to the power of the time taken give the amplitude of 0.1 mm.
Correct option:
The amplitude will reach 0.1 mm in about 7 secondsWhat is the exponential decay rate and how is it used?The given parameters are;
The initial amplitude = 0.75 mm
The decay rate, i = 25%
Required:
The time it takes the guitar to decay to 0.1 mm.
Solution:
The series of the sizes of the amplitude that has constant decay uses an
exponential decay formula.
When the amplitude is 0.1 mm, we have;
y = a·rⁿ
Where;
r = 1 - i
a = 0.75
n = The time taken
Which gives;
r = 1 - 0.25 = 0.75
y = 0.1 = 0.75 × 0.75ⁿ
[tex]\dfrac{0.1}{0.75} = \mathbf{0.75^{n}}[/tex]
[tex]n = \dfrac{ln\left( \dfrac{0.1}{0.75} \right)}{ln(0.75)} \approx \mathbf{7.0}[/tex]n = 7.0
The time it takes the amplitude to reach 0.1 mm is 7 seconds.Learn more about exponential growth and decay formula here:
