Answer:
No
Step-by-step explanation:
30% is the same as 3/10
3/7 is about the same as 43%
There is a difference among the percentage so no it's not correct
Yes, the value 30% of 70 is the same as 3/7 of 70.
What is an expression?Expression in maths is defined as the relation of numbers variables and functions by using mathematical signs like addition, subtraction, multiplication, and division.
To show this mathematically, we can start by calculating 30% of 70:
30% of 70 = (30/100) x 70
= 0.3 x 70
= 21
Now, let's calculate 3/7 of 70:
3/7 of 70 = (3/7) x 70
= 30/100 x 70
= 0.3 x 70
= 21
As we can see, both calculations give us the same result of 21. Therefore, 30% of 70 is the same as 3/7 of 70.

You deposit $500 in an account that earns 6.5% annual interest compounded yearly. Write a function that represents the balance y (in dollars) after x years.
Answer:
f(x)=.65+y
Step-by-step explanation:
.
The function for compound interest is A = 500 ( 1.065 )ˣ
What is Compound Interest?Compound interest is interest based on the initial principle plus all prior periods' accumulated interest. The power of compound interest is the ability to generate "interest on interest." Interest can be added at any time, from continuously to daily to annually.
The formula for calculating Compound Interest is
A = P ( 1 + r/n )ⁿᵇ
where A = Final Amount
P = Principal
r = rate of interest
n = number of times interest is applied
b = number of time periods elapsed
Given data ,
Let the compound interest amount be represented as A
Now , the interest rate r = 6.5 %
The number of times the interest is applied = yearly
The principal amount P = $ 500
n = 1 ( compounded yearly )
t = x ( number of years )
So, the function that represents the balance y (in dollars) after x years is:
y ( x ) = 500 ( 1 + 0.065/1 )ˣ
On simplifying , we get
y ( x ) = 500 ( 1.065 )ˣ
Hence , the function is A = 500 ( 1.065 )ˣ

Answer:
No solutions
Step-by-step explanation:
4(2r + 3) = 15r - 11 + 1 - 7r
Distribute:
8r + 12 = 15r - 11 + 1 - 7r
Combine like terms:
8r + 12 = 8r - 10

Mare has a monthly cell phone plan that has a fixed charge of $12 per month plus
$0.30 per text message. Marie wants to spend no more than $40 per month on her
call phone. Which inequality represents the number of text messages, X, that Marie
Please hurry
You need to multiply the cost per text message by the number of messages (x) add that to the fixed charge.
The total of those need to be less than or equal to the amount she wants to spend.
The equation would be written as:
0.30x + 12 <= 40
Solve for x. 3 - √x = 0
Answer:
x = 9
Step-by-step explanation:
3 - √x = 0
Subtract 3 from both sides of the equation
3 - 3 - √x = 0 - 3
-√x = -3
Divide both sides by -1
-√x / -1 = -3 / -1
√x = 3
Take the square of both sides
(√x) ² = 3²
X = 9

Two trains leave the station at the same time, one heading east and the other west. The eastbound train travels at 80 miles per hour. The westbound train travels at 90 miles per hour. How long will it take for the two trains to be 204 miles apart?
Do not do any rounding.
Answer:
one hour and 12 minutes
Answer:
1 hour and 12 minutes
Step-by-step explanation:
Let's say x = time it takes for the trains to be 204 miles apart.
Speed = Distance/Time,
Time = Distance/Speed,
x = 204/ (80 + 90) = 204/170 = 1 and 1/5 hours or 1 hour and 12 minutes
