30. The perimeter of a rectangle is 292 feet. The length of the rectangle is 4 feet less than 5 times the width. What is the length and width of the rectangle?
a. length = 121, width = 25b. length = 114.3, width = 23.7
c. length = 25, width = 121d. length = 121.7, width = 24.3
Final answer:
To find the dimensions of the rectangle, the problem was solved by setting up and solving equations based on the given perimeter and the relationship between the length and the width. It was found that the width is 25 feet and the length is 121 feet.
Explanation:
To solve the problem, we first need to set up equations based on the information given. We are told the perimeter of a rectangle is 292 feet and that the length (L) is 4 feet less than 5 times the width (W). The formulas for the perimeter (P) of a rectangle is P = 2L + 2W. The relationship between the length and the width can be expressed as L = 5W - 4.
Substituting the second equation into the first, we get: 292 = 2(5W - 4) + 2W.
Simplifying, we find that 292 = 10W - 8 + 2W, leading to 300 = 12W. Therefore, W = 25 feet. Substituting back to find L, we find that L = 5(25) - 4 = 121 feet.
Thus, the width of the rectangle is 25 feet, and the length is 121 feet, which corresponds to option C).
The lizards in the show eat 250 crickets per week.About how any crickets do the lizards eat each day?Explain.
Each day the lizards eat about 36 crickets when we round to the nearest whole number
To calculate how many crickets the lizards eat each day, we need to divide the weekly intake by the number of days in a week. The lizards eat 250 crickets per week. There are 7 days in a week.
So, we divide 250 by 7 which equals approximately 35.71 crickets per day.
Therefore, each day the lizards eat about 36 crickets when we round to the nearest whole number, since you can't have a fraction of a cricket.

what is 5y-4=-3x in standard form
The required standard form is 5y + 3x = 4 of the given linear equation.
What is the standard form of a linear equation?A linear equation in one variable indicates an equation with just one variable. This indicates that there is just one solution to this linear equation. The standard or generic form of linear equations in one variable is expressed as follows:
Ax + B = 0
In this equation, A and B are integers, and x is a variable.
Ax + By = C is the standard form for a line equation. In this situation, using the equation 5y-4=-3x B=5 and A=-3 and C=-4, we may add both -4 and -3x to both sides to get Ax and By on the same side, and we get 5y+3x=4.
Thus, the required standard form is 5y + 3x = 4 of the given linear equation.

The product of the expressions (3p⁴)³ * (p²)⁷ is 27p²⁶
How to evaluate the product of the expressions
From the question, we have the following parameters that can be used in our computation:
(3p⁴)³ * (p²)⁷
Expanding the brackets, we have
(27p¹²) * (p¹⁴)
Remove the brackets
So, we have
27p¹² * p¹⁴
Evaluate using the law of indices
27p²⁶
Hence, the product of the expressions is 27p²⁶

Which of the following is being constructed in the image?
A) a line perpendicular to a given lune through a point on the line
B) a line segment that is congruent to a given line segment
C) a perpendicular bisector of a line segment
D) a line parallel to a given line through a point not on the line
Answer:
A) a line perpendicular to a given line through a point on the line.
Step-by-step explanation:
Perpendicular means at a 90 degree angle.
As we can see, the arcs are crossing on a dotted line that is going through a point, and is perpendicular to the line the point is on.

A computer password is to consist of 6 letters, none of which are used more than once. For security reasons, the letters Q and Z are not to be used in the first position. How many different passwords are possible?
The total number of possible 6-letter computer passwords, without repetition and with restrictions on the first letter, is 7,893,600.
Explanation:The question involves finding out the number of possible combinations for a 6-letter computer password where no letter is repeated and the letters 'Q' and 'Z' are not allowed in the first position.
For the first letter, we have 24 options (26 letters in the alphabet minus the two restricted letters, 'Q' and 'Z'). For the second letter, since the first letter has already been chosen and cannot be repeated, there are 25 options left. This pattern continues, reducing by one each time, leaving 24 options for the third, 23 for the fourth, 22 for the fifth, and 21 options for the sixth letter. The total number of possible passwords is calculated by multiplying all options together; hence, the answer will be 24 * 25 * 24 * 23 * 22 * 21.
The calculation yields a result of 7,893,600 possible passwords.
To find the number of different passwords possible, multiply the number of choices for each position: 24 * 25 * 24 * 23 * 22 * 21 = 39,825,600.
Explanation:To find the number of different passwords that are possible, we can break down the problem into steps:
First position: Since Q and Z cannot be used in the first position, there are 24 possible letters that can be used.Second position: Once the first position is determined, there are 25 letters remaining to be used in the second position (since Q and Z can now be used).Third position: There are 24 letters remaining to be used in the third position, since one letter has already been used in the first position.Fourth position: There are 23 letters remaining to be used in the fourth position.Fifth position: There are 22 letters remaining to be used in the fifth position.Sixth position: There are 21 letters remaining to be used in the sixth position.To find the total number of possible passwords, we multiply together the number of choices for each position: 24 * 25 * 24 * 23 * 22 * 21 = 39,825,600. Therefore, there are 39,825,600 different passwords that are possible.
