If the effective annual interest rate of a loan is 14.6%, what is the nominal annual interest rate, correct to one decimal
place, if interest compounds monthly?
Answer:
13.7%
Step-by-step explanation:
Nominal interest rate = [tex](\sqrt[m]{1 + effective annual interest rate} - 1 \ ) m[/tex]
where m = number of compounding = 12
([tex]\sqrt[12]{1.146}[/tex] - 1 ) x 12 = 0.137054 = 13.7%
To round to one decimal place means that there should be only one figure after the decimal place.

Which equation can you use to find the value of x?
78°
3xº
(x - 2)
3x + 78 + x - 2 = 180
3x = 78
3x = 78 + x - 2
78 = x-2
Answer:
3×=78+×-2

Can you help me step by step
Answer:
n = -7
Step-by-step explanation:
n - 7/4 = 35/12 + 5/3n
subtract n from both sides of the equation:
-7/4 = 35/12 + 2/3n
convert -7/4 to -21/12:
-21/12 = 35/12 + 2/3n
add 21/12 to both sides:
0 = 56/12 + 2/3n
convert 2/3n to 8/12n:
0 = 56/12 + 8/12n
subtract 56/12 from each side:
8/12n = -56/12
multiply both side by 12:
8n = -56
divide both sides by 8:
n = -7

2. Dwayne scored 55 points in the last basketball game, which is 10 points more than his previous personal best. Lebron scored 15 points more than Chris in the
same game. Lebron scored the same number of points as Dwayne’s previous personal best.
Write two algebraic equations, let d represent the number of points Dwayne scored during his previous personal best and c represent the number of Chris’s points.
Answer:
Required equations are:
d + 10 = 55c + 15 = dSolving the first, we get:
d = 55 - 10d = 45Solving the second we get:
c + 15 = 45c = 45 - 15c = 30Can anyone help me pls? Ur a legend if u can!

A right triangle is formed by connecting coordinates (5, -2), (2, -3), and (-1, 6). What is the area of the triangle in square units?
Answer:
the triangle formed from the coords is 3cm by 9cm so try 3 × 9 = 27 then 27 ÷ 2 = 13.5 from the formula a = ½bh?
Step-by-step explanation:
The area of the triangle is equal to 25√2 square units.
What is coordinate geometry?A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.
Given that a right triangle is formed by connecting coordinates (5, -2), (2, -3), and (-1, 6).
The area will be calculated as,
Side = √ [ ( -3 + 2 )² + ( -2 - 5 )² ]
Side = √ ( 1 + 49)
Side = √50
Base = √ [ ( 6 + 3 )² + ( -1-2)² )
Base = √ ( 81 + 9 )
Base = √100
The area will be calculated as,
Area = (1/2) x B x H
Area = (1/2) x √50 x √100
Area = (1/2) x √50 x 10
Area = 5 x √( 25 x 2 )
Area = 25√2 square units

PLEASE HELP ASAP THANK YOUU: A unicycle wheel makes five rotations. The unicycle travels 37.94 feet. Find the diameter of the wheel in inches.
Show your work and write your answer in a sentence.
Answer:
diameter of the wheel = 28.98 in (2 d.p.)
Step-by-step explanation:
Given information:
A unicycle wheel makes five rotationsThe unicycle travels 37.94 feetCircumference of a circle = πd (where d is the diameter)
One rotation of the wheel is equal to the circumference of the wheel.
Therefore, 5 rotations is equal to the sum of 5 circumferences.
To find the diameter of the wheel in feet, equate the expression for 5 circumferences to the total distance traveled and solve for d:
[tex]\begin{aligned}\textsf{5 circumferences} & = \textsf{total distance traveled}\\\implies 5 \pi d & = \sf 37.94\: ft\\d & = \sf \dfrac{37.94}{5 \pi}\\d & = \sf 2.415335416... \:ft \end{aligned}[/tex]
As 1 foot = 12 inches, multiply the found diameter in feet by 12 to calculate the diameter in inches:
[tex]\begin{aligned}d & =2.415335416... \times 12\\\implies d & = \sf 28.98\:\:in\:(2\:d.p.)\end{aligned}[/tex]
Therefore, the diameter of the wheel is 28.98 in (2 d.p.).

Kelli Rae invested $220,000 in a savings account with simple interest. After 10 years, Kelli Rae had $250,000. What is the interest rate on this account?
Answer:
Interest rate = 1.363% (Approx.)
Step-by-step explanation:
Given:
Amount invested P = $220,000
Amount after 10 year = $250,000
Number of year = 10 year
Find:
Interest rate
Computation:
A = P + I
Amount of interest = $250,000 - $220,000
⇒ Amount of interest = $30,000
Amount of interest = PRT
⇒ 30,000 = (220,000)(R)(10)
⇒ 30,000 = (2,200,000)(R)
⇒ R = 0.013636
Interest rate = 1.363% (Approx.)
