Find the perimeter of the square
Answers
Answer:
156
Step-by-step explanation:
4x + 3 = 3(2x - 5)
4x + 3 = 6x - 15
3 = 2x - 15
2x = 18
x = 9
4(9) + 3
= 36 + 3
= 39
39 * 4 = 156
Hope it helps!
Answer: 156 inches
Step-by-step explanation:
So we know that all of the sides are equal to each other.
Now we need to know what x equals.
4x + 3 = 3(2x -5)
4x + 3 = 6x - 15
3 = 2x -15
18 = 2x
9 = x
Plug 9 into one of the equations.
4(9) + 3
36 + 3 = 39
39 * 4 = 156
Perimeter = 156 inches

[~S & (R V S) ] ≡ (Q ⊃ S) where A = T, S = F, R = F, Q = T
Answers
[~S & (R V S)] ≡ (Q ⊃ S) is true when A = T, S = F, R = F, and Q = T by substituting the propositional variables.
What is truth table?A truth table is a table used to determine the truth values of a compound proposition, which is a logical statement made up of simpler propositions using logical operators such as "and" (represented by "&"), "or" (represented by "V"), "not" (represented by "~"), conditional (represented by "⊃"), and biconditional (represented by "≡").
According to question:Let's substitute the given truth values for the propositional variables in the given statement:
[~F & (F V F)] ≡ (T ⊃ F)
Using the truth table for conjunction (represented by "&") and disjunction (represented by "V"), we can simplify the left-hand side of the equivalence:
[T & F] ≡ (T ⊃ F)
Using the truth table for conditional (represented by "⊃"), we can simplify the right-hand side of the equivalence:
F ≡ F
Since both sides of the equivalence have the same truth value, the statement is true.
Therefore, [~S & (R V S)] ≡ (Q ⊃ S) is true when A = T, S = F, R = F, and Q = T.

Which of the following are negative reciprocals?

B. 3/4 & -3/4
C. 3/4 & 4/3
D. 3/4 & 3/4
Answers
Answer:
option A is the answer because -4/3 is both negative and reciprocal of 3/4
Answer:
A. 3/4 & -4/3
Step-by-step explanation:
Negative reciprocal is the negative of the value and the numerator/denominator is switched to denominator/numerator.
For example, -7/15.
-7 is the numerator because -7 is above 15. But if we switch that, it will become -15/7. If we turn it from negative to positive or positive to negative, which in this case is negative to positive, since negative x negative is positive, it will become 15/7.

Answers
Answer:
Step-by-step explanation:
The domain and range of a linear function is always real numbers (T or F)
It is True. This is because of a couple of reasons.
1.) You cannot divide by 0.

The range is determined by the domain in a linear function, and thus it must always consist of real numbers.

For a $200,000 mortgage, with an interest rate of 4% paid over 20 years, the monthly payment is $1,211.96. After one month, what is the balance of the loan? Give your answer to the nearest dollar.
Answers
The balance on the loan will be $198,908.
Based on the information given, the amount of interest for the first month will be:
= $200,000 × 0.0412
= $666.67
During the first month, the amount subtracted from the loan will be:
= $12111.96 - $666.67
= $545.29.
The interest accrued for the second month will be:
= $199454.71 × 0.0412
= $664.85
Therefore, the balance on the loan after the second month will be:
= $199454.71 - $547.11

The question we have to solve is:

Miss Lianto mowed 2 7 of her lawn. Her son mowed 1 3 of it. Who mowed most of the lawn? How much of the lawn still needs to be mowed?
HURRY!!!!!!!!!!!!!!!!!!!!!!!!!
Answers
8/21 of the lawn still needs to be mowed.
To compare fractions, we need a common denominator. The least common multiple of 7 and 3 is 21.
Miss Lianto's fraction: (2/7) x (3/3) = 6/21
Son's fraction: (1/3) x (7/7) = 7/21
To calculate how much of the lawn still needs to be mowed, we can subtract the combined fractions mowed from the total:
Combined fractions mowed: 6/21 + 7/21 = 13/21
So, Remaining fraction: 1 - 13/21 = 8/21
Therefore, 8/21 of the lawn still needs to be mowed.

You deposit $50,000 into a bank account that earns 2.5% simple interest annually.
How much will be in the account at the end of 4 years?
Answers
Step-by-step explanation:
To calculate the amount of money in the account at the end of 4 years, we can use the formula for simple interest:
I = P * r * t
Where:
I = Interest earned
P = Principal amount (initial deposit)
r = Annual interest rate (as a decimal)
t = Time period (in years)
Plugging in the given values, we get:
I = $50,000 * 0.025 * 4
I = $5,000
This means that over the course of 4 years, the account will earn $5,000 in interest.
To find the total amount in the account at the end of 4 years, we simply add the interest earned to the initial deposit:
Total amount = $50,000 + $5,000
Total amount = $55,000
Therefore, at the end of 4 years, there will be $55,000 in the account if you deposit $50,000 into a bank account that earns 2.5% simple interest annually.
