Answer:
60 compounding periods
Step-by-step explanation:
The proper formula for compound interest is A = P(1 + r/n)^(nt), where r is the interest rate as a decimal fraction, n is the number of times that interest is compounded in 1 year, and t is the number of years.
In this problem, we don't need to calculate the Amount, but only the number of compounding periods. That is nt, which here is 12*5, or 60.
Find each percent change. Round to the nearest tenth of a percent. State if it is an increase or decrease. From 79 miles to 84 miles
A) 6.3% decrease
B) 5% increase
C) 6% decrease
D) 6.3% increase
Answer:
the answer is d.
Step-by-step explanation:
first, you want to use the formula,
new value - original value
____________________
original value * 100
you see that 84 is the new value and 79 would be the original value. substitute the numbers in. this is a increase since you will get a positive value.
84 - 79
______
79 * 100
now we solve it.
5
__
79 * 100
you can either solve the fraction first then multiply that by 100 or multiply the numerator by 100 first then divide that by 79, each way works.
500
____
79 = approximately 6.3% increase (this is not a exact value, just rounded)
or
5
__
79 = approximately 0.063 (this is not a exact value, just rounded)
0.063 * 100 = 6.3% increase

A line that passes through the points (-3,5) and (6,10)
Answer:
y = 5/9x + 19/3
Step-by-step explanation:
slope: 10 - 5 / 6 - (-3) = 5/9
point-slope form:
y - 5 = 5/9(x + 3)
y -5 = 5/9x + 4/3
y = 5/9x + 6 1/3

A pack of 5 of board games costs $75.
If there is a direct proportion between the price (y) and number of board games (2), which equation represents the
situation?
A
y = 2
y = 15.2
y = 52
y = 75.00
Answer:
C. y=5x
Step-by-step explanation:
I'm pretty sure that it's y=5x, because it says that y represents the price, and that 2 represents that amount of board games. The price is $75, and the number of board games is 5. So the answer should be y=5x.

The radius of a basketball is 10 inches, and the radius of a soccer ball is 9 inches. How much greater is the volume of the basketball than the soccer ball? Round the nearest tenth.
Answer:
The basketball volume is 1135.2 in³ greater than the soccer ball volume.
Step-by-step explanation:
Basketball volume is V = (4/3)πr³, or V = (4/3)(3.14)(10 in)³ = 4188.79 in³
Soccer ball volume is V = (4/3)πr³, or V = (4/3)(3.14)(9 in)³ = 3053.63 in³
Subtract the smaller from the larger to determine how much greater the large ball volume is:
4188.79 in³ - 3055.63 in³ = 1135.2 in³
Answer:
1135.2
Step-by-step explanation:
1135.2

Answer:
A) 180 square feet.
Step-by-step explanation:
The two rectangles are congruent, therefore having the same area.
The area of a rectangle, or any quadrilateral for that matter, is Length x Width.
12 * 4 = 48
There are two, so multiply this number by 2 and you get 96.
The formula for a trapezoid's area is height * 1/2 * (base 1 + base 2)
The height given is 6 feet. The 1st base is 10 feet, and the longer base is 10 + 4 + 4, this equals 18
The formula is now
[tex]6 * \frac{1}{2} (18 + 10)\\6 * \frac{1}{2} (28)\\6* 14\\=84[/tex]
Now in total, 84 + 96 = 180.

Este curso nuestro instituto tiene 473 alumnos. Si nos dicen que respecto al curso anterior se ha producido un aumento de inscripciones del 10 %, ¿cuántos alumnos había el curso anterior?
Answer:
En el curso anterior había 430 alumnos.
Step-by-step explanation:
El curso tiene 473 alumnos. Nos dicen que respecto al curso anterior se ha producido un aumento de inscripciones del 10 %. Entonces, siendo x la cantidad de alumnos que había en el curso anterior, se puede plantear la ecuación:
x + 0.1*x= 473
Resolviendo se obtiene:
1.1*x=473
x= 473 ÷1.1
x= 430
En el curso anterior había 430 alumnos.
The school orchestra is creating a CD of their last concert. The total cost to make the CD is $300 plus $2.50 per CD. They are selling the CDs for $10 each. How many CDs will they need to sell to make a profit?
Answer:
They need to sell more than 40 CDs to make a profit.
Explanation:
They will make a profit when the sales are higher than the cost and with the information provided, you can write the following inequality:
10x>300+2.5x, where x is the number of CDs sold
Now, you can solve for x:
10x-2.5x>300
7.5x>300
x>300/7.5
x>40
According to this, the answer is that they need to sell more than 40 CDs to make a profit.
Dennis stood on a 9 foot ladder to measure the sunflower. How much taller is the tallest sunflower than the ladder?
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]Ladder = 9ft[/tex]
[tex]Tallest\ Sunflower = x[/tex]
Required
How much taller is the tallest
To get this, we simply calculate the difference between the height of the tallest sunflower and the ladder.
i.e.
[tex]Difference = Tallest\ Sunflower - Ladder[/tex]
[tex]Difference = x - 9[/tex]
-----------------------------------------------------------------------------------------------------
If for instance, the tallest is 13ft, then it is 4ft taller.
Because:
[tex]Difference = 13ft - 9ft[/tex]
[tex]Difference = 4ft[/tex]

22-9x=9x+10
Answer:
x= 2/3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
22−9x=9x+10
22+−9x=9x+10
−9x+22=9x+10
Step 2: Subtract 9x from both sides.
−9x+22−9x=9x+10−9x
−18x+22=10
Step 3: Subtract 22 from both sides.
−18x+22−22=10−22
−18x=−12
Step 4: Divide both sides by -18.
x=2/3
