Answer:
x = 2.8
Step-by-step explanation:
x/7 = 0.4
multiply both sides by 7
0.4*7 = 2.8
x = 2.8
A binomial is an expression that has two terms.
(1) Has a single term
(2) Has two terms
(3) Has three terms
(4) Has a single term
So the only binomial out of the answers is (3)
Answer:
The sum of 4 times a number and -3 added to 9 times the number is:
4x + (-3 + 9x)
Step-by-step explanation:
Determine what each of the words means
"the sum of" - you are going to be adding the following two numbers.
"4 times a number" - Let x be the number, so, 4x is the first number.
"and -3 added to" - again, it's going to be addition of this number and the following number.
"9 times the number" - let x be the number, so, 9x is the second number in the second addition.
Now that we know what it all means, put it together:
4x + (-3 + 9x)
I really hope this helps you =)
Answer: $45451
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = 25000
r = 3% = 3/100 = 0.03
n = 4 because it was compounded 4 times in a year.
t = 20 years
Therefore,
A = 25000(1+0.03/4)^4 × 20
A = 25000(1+0.0075)^80
A = 25000(1.0075)^80
A = $45451
Answer:
B. A hill that rises 2 feet for every 15 feet of run.
Step-by-step explanation:
The two must have COPs. We'll narrow them down.
For A, we divide 10 by 2.
For B, we divide 15 by 2.
B has the larger number, so it is B.
