ozzi

Answer:

y = 6x - 2

Step-by-step explanation:

slope intercept form is y = mx + b

m = slope

b = y-intercept

They give us the slope (m) which is 6 and the y-intercept (b) which is -2. PLug it into the equation

y = mx + b

y = 6x - 2

Simple Interest Rate Formula: $\displaystyle A = P(1 + r)^t$

A is final amount
P is principle (initial) amount
r is rate
t is time (in years)

Step-by-step explanation:

Step 1: Define

P = 7200

r = 0.75% = 0.0075

t = 5

Step 2: Solve for A

Substitute in variables [Simple Interest Rate Formula]: $\displaystyle A = 7200(1 + 0.0075)^5$
(Parenthesis) Add: $\displaystyle A = 7200(1.0075)^5$
Evaluate exponents: $\displaystyle A = 7200(1.03807)$
Multiply: $\displaystyle A = 7474.08$

Solving with percent and percent problems

Marysya12 [62]

Well, if 0.4% was defected, then 99.6% of the parts are good, because 100-0.4 is 99.6. Multiply 99.6% with 54650, and you get 54431.4. You should round down, because you can't have parts of parts. So, 54431 parts were good.

How do you round to two decimal places ?? i just have the normal answers btw. asap!! :(

Evgen [1.6K]

Answer:

Step-by-step explanation:

Look at the 3rd decimal digit (the digit after the hundredths).

if it is the digit is less than 5 then round the number down by taking away the decimal point of the number after the 2nd decimal place;

However if it is 5 or more then round the number up by adding one on to the hundredths digit and removing the rest of the decimal part of the number after it

For example,4.749 rounds up to 4.75 because the 3rd decimal digit is a 9.

I hope this helps ^^
