Boris rented a truck for one day. There was a base fee of $16.95, and there was an additional charge of 89 cents for each mile driven. Boris had to pay $131.76
when he returned the truck. For how many miles did he drive the truck?

Answers

Boris drove the truck 129 miles. You take how much the base fee (16.95) and subtract it from the total of how much he had to pay (131.79). The problem would look like $131.79 - $16.95 = $114.84. Then would would take 114.84 and divide it by the cost of one mile. This problem would look like $114.84 divided by $0.89 = 129. This means the driver drove 129 miles! I hope this helps!

Step-by-step explanation:

Which of the following statements are true about inverse matrices?

All square matrices have inverses.

If A and B are inverse matrices, then A and B must be square matrices.

The determinant of a singular matrix is equal to zero.

If A and B are inverse matrices, then A + B = I.

If A and B are inverse matrices, then det(A)xde(B)=0

Any zero matrix does not have an inverse.

If B = A–1, then A = B–1.​

Answers

B = A–1, then A = B–1.​ This statement is true. The inverse of a matrix is unique, so if B is the inverse of A, then A must be the inverse of B.

what is matrix ?

An arrangement of integers in both columns and rows is known as a matrix. learns about matrices' components and dimensions and first presents them. A matrix is a rectangular grid with integers arranged in rows and columns.

The statements that are true about inverse matrices are:

Not all square matrices have inverses. A square matrix only has an inverse if its determinant is not equal to zero. If the determinant of a square matrix is zero, it is called a singular matrix and does not have an inverse.

If A and B are inverse matrices, then A and B must be square matrices. This is because only square matrices can have inverses.

The determinant of a singular matrix is equal to zero. This is because the determinant of a matrix is related to the linear independence of its columns or rows. A singular matrix has linearly dependent columns or rows, which means its determinant is zero.

If A and B are inverse matrices, then A + B = I. This is not necessarily true. In general, the sum of two inverse matrices is not necessarily the identity matrix.

If A and B are inverse matrices, then det(A) x det(B) = 1. This statement is almost true, but the correct statement is det(A) x det(B) = det(AB) = 1.

Any zero matrix does not have an inverse. This is because the determinant of a zero matrix is zero, and therefore it is singular and does not have an inverse.

If B = A–1, then A = B–1.​ This statement is true. The inverse of a matrix is unique, so if B is the inverse of A, then A must be the inverse of B.

Twice the difference of a number and 2 is added to 6 and the result is 4 more than 3 times the number.

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

Given the statement:

''Twice the difference of a number and 2 is added to 6 and the result is 4 more than 3 times the number''.

Let us break down the statement into an algebraic expression.

First Portion:

Let the number be: n

The difference of a number n and 2: n -2

Twice the difference of a number n and 2: 2(n-2)

Twice the difference of a number and 2 is added to 6 = 2(n-2) + 6

Second Portion:

3 times the number n:  3n

4 more than 3 times the number: 3n + 4

Combine the First portion and Second Portion:

Twice the difference of a number and 2 is added to 6 and the result is 4 more than 3 times the number:

2(n - 2) + 6 = 3n + 4

Therefore, the required algebraic expression is:

2(n - 2) + 6 = 3n + 4

BONUS SOLUTION to determine the number n

Let us solve the expression

2(n - 2) + 6 = 3n + 4

2n - 4 + 6 = 3n + 4

flip the equation

3n + 4 = 2n - 4 + 6

3n + 4 = 2n + 2

3n - 2n = 2 - 4

n = -2

Thus, the value of n = -2

Find the geometric mean of sqrt 77 and sqrt 343.

Answers

Answer:

12.75

Step-by-step explanation:

The computation of the geometric mean of sqrt 77 and sqrt 343 is given below:

As we know that

Geometric mean = [tex]\sqrt{ab}[/tex]

where

a is the first number = [tex]\sqrt{77}[/tex]

And, the b is the second number = [tex]\sqrt{343}[/tex]

Now first we have to convert into a number

For a it, is = 8.78

And, for b, it is = 18.52

Now the geometric mean is

[tex]= \sqrt{8.78 \times 18.52}[/tex]

= 12.75

(0.85). 32 represents the final price of the cake in dollars because...​

Answers

Answer: 1. $45*1.07 | $45(1.07) 2. (0.85)*32 represent the final price of the cake in dollars because (0.85) is the 15% off in decimals.

Step-by-step explanation:

1 if you multiply 45 by 1.07 it will be 48.15 and that's the final cost of the book, same with $45(1.07) is just another way to represent the multiplication.

2 As I said the 0.85 represent the 15% off, and when you multiply it will be less.

a bus accelerates from 2 m/s to 10 m/s in 5 seconds. What was its average acceleration?

Please Help

Answers

Answer:

I believe the answer is 4. Please correct me if I’m wrong.

Step-by-step explanation:

Answer:  1.6 m/s^2

================================================

Work Shown:

A = old velocity = 2 m/s

B = new velocity = 10 m/s

C = change in time = 5 seconds

D = average acceleration

D = (change in velocity)/(change in time)

D = (B-A)/C

D = (10-2)/5

D = 8/5

D = 1.6 m/s^2

The acceleration 1.6 m/s^2 means that the velocity is increasing by 1.6 m/s for every second.
