deposited $7,500 into a savings account 5 years ago. The simple interest rate is 2%. How much money did earn in interest?
Answer:
$750
Step-by-step explanation:
simple interest equation is:
I (interest) = P (principal) x R (interest rate, as a decimal) x T (time, in years)
I = 7500 x .02 x 5
I = 750
Form 8B were investigating how a metal bar expands while being heated. The bar
was originally 30 cm in length and it expanded to 31.75 cm.
Calculate the percentage increase in length. Give your answer correct to 1 decimal
place.
Answer:
5.8%
Step-by-step explanation:
to work out percentage increase:
(new value - original value) ÷ original value and times it all by 100
((31.75-30) ÷ 30) × 100
=5.8% (1dp)
A shop has a sale that offers 20% off all prices.On the final day reduce all the sale prices by 25%.Linz buys a radio on the final day.Work out the overall percentage reduction on the price of the radio
Answer:
40%
Step-by-step explanation:
Original price = x
Sale = 20% off
20% / 100 = 0.2 to convert from a percent to a decimal
Sale = x - 20% of x = x - 0.2x = 0.8x
Sale price = y = 0.8x
Reduction of sale prices = 25% = 0.25
Reduction = y - 25% of y = y - 0.25y = 0.75y
End price in terms of original price (x):
0.75y = 0.75(0.8)x
= 0.6x
End price = 0.6 or 60% of original price, coming out to a 100-60 = 40% overall percentage reduction
what is _ percent of 100 is 14
Answer:
It should be 14 percent.
Step-by-step explanation:
14 percent is just 14/100, which if you multiply by 100 gives you 14.
14%
Step-by-step explanation:
Whenever you have anything over 100 (e.g 40/100) that number is always gonna be 40. Like multiplying by 1. 9*1 is 1. Assume the 9 is 90 and assume the 1 is 100. It's always gonna be the numerator instead of the denominator.

Point slope form question
How would I turn (2,-5) (-3, 10) into a point slope equation?
Answer:
y+5=-3(x-2)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(10-(-5))/(-3-2)
m=(10+5)/-5
m=15/-5
m=-3
y-y1=m(x-x1)
y-(-5)=-3(x-2)
y+5=-3(x-2)

Step-by-step explanation:
A bacterial population has an exponential growth rate of 11.2% per hour. If there were 480 bacteria initially, what would the bacterial population be after 5 hours
The number of bacterial population after 5 hours is; 816
The formula for the exponential growth of the population is;N(t) = N_o(1 + r)^(t)
Where;
N(t) is number of bacteria after t hours
N_o is number of bacteria initially
r is growth rate
t is time
We are given;N_o = 480
r = 11.2% = 0.112
t = 5
Thus;N(5) = 480(1 + 0.112)^(5)
N(5) = 816.14
Approximating to a whole number gives; N(5) = 816 bacteriaRead more about exponential growth at; https://brainly.com/question/15316908

Julio won a contest. His cash prize is given to him in the following way:
On the first day, Julio will receive $0.25.
For each successive day, the amount of money Julio receives doubles.
a. Write an explicit formula to represent the amount of money, f (d), in dollars, Julio receives d days after the first day.
b. How much money will Julio receive on the tenth day?
Julio will receive $ 128 on the tenth day.
Given that Julio won a contest, and his cash prize is given to him in the following way: On the first day, Julio will receive $ 0.25, and for each successive day, the amount of money Julio receives doubles, to determine an explicit formula to represent the amount of money, f (d), in dollars, Julio receives d days after the first day, and determine how much money will Julio receive on the tenth day, the following calculations must be performed:
0.25 x 2 ^ D = F 0.25 x 2 ^ 9 = F 0.25 x 512 = F 128 = F
Therefore, Julio will receive $ 128 on the tenth day.

Write the equation of the line that is perpendicular to y=3x-6 and passes through the point
x, y
(2,0)
Perpendicular is the negative reciprocal so the slope is -1/3
Need to know b and the full equation
With work please. Thank you!
Answer:
y=-1/3x+2/3 (please mark brainliest)
Step-by-step explanation:
start with y=3x+6
you can get the slope of the perpendicular line by dividing the slope by -1,
so the slope of the new line is -1/3.
using the point and the slope of the new line, we can put it into point-slope form:
y-y₁=m(x-x₁)
y-0=-1/3(x-2)
simplify:
y=-1/3x+2/3
this is the final equation in the form y=mx+b

Answer:
1 1/8 mile
Step-by-step explanation:
when it says altogether most of the time you're supposed to add.
When you add fractions you need to have both denominator (number below the line) be the same. and sense 1/2 and 4/8 are equal we will replace it.
you add the numerators (top numbers) and keep the denominator (bottom number)
[tex]\frac{4}{8} + \frac{5}{8} = \frac{9}{8} =1\frac{1}{8}[/tex]
Sense the numerator is bigger you subtract the bottom number from the top number and put a 1 in front of the fraction.
