x + 300 = 450 is the correct answer. This is becuause the unknown amount, x, is how much she put in the bank. $450 is her total, so it would be equal to 450. If she already had 300, you need to firgure out what she added to 300 to make the answer 450, so the correct answer is x + 300 = 450.
During the 2011 season, a quarterback passed for 302 yards per game. He played in all 16 regular season games that year.
a. For how many total yards did the quarterback pass?
b. If he matches this passing total for each of the next 13 seasons, how many yards will he pass for in his career?
Answer:
(a). 4,832
(b). 62,816
Step-by-step explanation:
We have been given that during the 2011 season, a quarterback passed for 302 yards per game. He played in all 16 regular season games that year.
(a). To find the total yards passed by quarterback, we will multiply total number of games in one season by yards passed in one game.
[tex]\text{Total yards passed by quarterback in one season}=16\times 302[/tex]
[tex]\text{Total yards passed by quarterback in one season}=4,832[/tex]
Therefore, the quarterback passed 4,832 yards in one season.
(b). To find the total yards passed by quarterback in his career, we will multiply total number of yards passed in one season by 13.
[tex]\text{Total yards passed by quarterback in hos career}=13\times 4,832[/tex]
[tex]\text{Total yards passed by quarterback in hos career}=62,816[/tex]
Therefore, the quarterback passed 62,816 yards in his career.
Final answer:
The quarterback passed for a total of 4,832 yards during the 2011 season and is projected to pass for 62,816 yards in his entire career.
Explanation:
The questions can be answered as -
a. To find the total yards the quarterback passed during the 2011 season, we need to multiply the average yards per game by the number of games played.
Since he passed for 302 yards per game and played in all 16 regular season games, the total yards passed would be 302 x 16 = 4,832 yards.
b. If the quarterback matches this passing total for each of the next 13 seasons, we can find the total yards he will pass for in his career by multiplying his average yards per game by the number of games played in each season and then adding up the totals.
Since he passed for 4,832 yards in the 2011 season and plays 16 games per season, the total yards he will pass for in his career would be 4,832 x 13 = 62,816 yards.

An architect designs a rectangular flower garden such that the width is exactly two-thirds if the length. If 240 feet of antique picket fencing are being used to enclose the garden, find the dimensions of the garden.
Answer:
The length of the rectangular flower garden is 72 feet and the width is 48 feet
Step-by-step explanation:
Let
L ----> the length of the rectangular flower garden in feet
W ---> the width of the rectangular flower garden in feet
we know that
The perimeter of the rectangular flower garden is
[tex]P=2(L+W)[/tex]
we have that
[tex]P=240\ ft[/tex]
so
[tex]240=2(L+W)[/tex]
Simplify
[tex]120=(L+W)[/tex] -----> equation A
[tex]W=\frac{2}{3}L[/tex] ----> equation B
Substitute equation B in equation A and solve for L
[tex]120=(L+\frac{2}{3}L)[/tex]
[tex]120=\frac{5}{3}L[/tex]
[tex]L=120(3)/5[/tex]
[tex]L=72\ ft[/tex]
Find the value of W
[tex]W=\frac{2}{3}(72)[/tex]
[tex]W=48\ ft[/tex]
therefore
The length of the rectangular flower garden is 72 feet and the width is 48 feet

An audio books club charges an initial joining fee of $20.00. The cost per audio book is $15.00. The graph shows the cost of belonging to the club as a function of audio books purchased. How will the graph change if the cost per audio book goes up by $1.00?
(The new function is shown by the dotted line.)
Answer:
The new function will have a steeper slope
Step-by-step explanation:
Let
x ----> the number of audio books purchased
y ---->the cost of belonging to the club in dollars
we know that
case 1 (Originally)
[tex]y=15x+20[/tex] ----> equation A
case 2 ( the cost per audio book goes up by $1.00)
The new equation is
[tex]y=(15+1)x+20[/tex]
[tex]y=16x+20[/tex]
The slope of the new function is greater than the slope of the original function
[tex]16\frac{\$}{audio\ book}>15\frac{\$}{audio\ book}[/tex]
The new function will have a steeper slope
The graph in the attached figure
If the cost per audio book goes up by $1.00, the graph will shift upward by $1.00 for every point on the graph.
Explanation:The graph represents the cost of belonging to an audio books club as a function of the number of audio books purchased. The x-axis represents the number of audio books and the y-axis represents the total cost. The initial joining fee of $20.00 is a fixed cost and stays the same regardless of the number of audio books purchased. The cost per audio book is $15.00. If the cost per audio book goes up by $1.00, the graph will shift upward by $1.00 for every point on the graph. This means the new function will be a parallel line to the original function, but shifted up by $1.00.

-2x + 2y = 6 and 4x + 2y= -5 solve by substitution
The solution to the system of equations by substitution is [tex]\( x = -\frac{11}{6} \)[/tex] and [tex]\( y = \frac{7}{6} \)[/tex].
To solve the system of equations by substitution, we can solve one equation for one variable and then substitute that expression into the other equation.
Given the system of equations:
1) [tex]\( -2x + 2y = 6 \)[/tex]
2) [tex]\( 4x + 2y = -5 \)[/tex]
From equation (1), we can solve for [tex]\( y \)[/tex] in terms of [tex]\( x \)[/tex]:
[tex]\[ -2x + 2y = 6 \][/tex]
[tex]\[ 2y = 2x + 6 \][/tex]
[tex]\[ y = x + 3 \][/tex] ... (i)
Now, substitute [tex]\( y \)[/tex] from equation (i) into equation (2):
[tex]\[ 4x + 2(x + 3) = -5 \][/tex]
Expand and solve for [tex]\( x \)[/tex]:
[tex]\[ 4x + 2x + 6 = -5 \][/tex]
[tex]\[ 6x + 6 = -5 \][/tex]
[tex]\[ 6x = -11 \][/tex]
[tex]\[ x = -\frac{11}{6} \][/tex]
Now, substitute [tex]\( x = -\frac{11}{6} \)[/tex] into equation (i) to find [tex]\( y \)[/tex]:
[tex]\[ y = -\frac{11}{6} + 3 \][/tex]
[tex]\[ y = -\frac{11}{6} + \frac{18}{6} \][/tex]
[tex]\[ y = \frac{7}{6} \][/tex]
So, the solution to the system of equations is:

dougs monthly salary was $1250 when he recieved a 5% raise. Six months later he recieved another 2% raise. What is his annual salary after recieving both raise?
Final answer:
After receiving a 5% and then a 2% raise, Doug's annual salary becomes $16,065.
Explanation:
Let's calculate Doug's annual salary after receiving both raises. Initially, Doug's monthly salary was $1250. After a 5% raise, his new monthly salary becomes $1250 × 1.05 = $1312.50.
Six months later, he receives another 2% raise, which makes his monthly salary $1312.50 × 1.02 = $1338.75.
To find his annual salary after both raises, we simply multiply his final monthly salary by 12 (the number of months in a year).
Initial monthly salary = $1250
First 5% raise = $1250 + 0.05 × $1250
Second 2% raise = (first raise + 0.02 × first raise)
Multiply the final salary by 12 to get the annual salary
$1338.75 × 12 = $16,065.
Therefore, Doug's annual salary, after receiving both a 5% and 2% raise, is $16,065.

Answer:
6 meters by 9 meters
Step-by-step explanation:
Step 1: Formula for perimeter of rectangle
Rectangle's perimeter = 2 (length) + 2 (width)
Rectangle's perimeter = 2 (length + width)
Step 2: Find the length and width in terms of x
Width = x
Length = 1.5 times width
Length = 1.5x
Step 3: Find x
Perimeter = 2(length + width)
30 = 2 (1.5x + x)
30/2 = 2.5x
15/2.5 = x
x = 6
Step 4: Find the length and width
Width = x = 6 meters
Length = 1.5x = 1.5(6) = 9 meters
Therefore, the dimensions of the room are 6 meters and 9 meters.

Answer:
5120oz/12=426.667 ounces.
Step-by-step explanation:
We know 1 pound = 16 oz. If we want to find out how many ounces are in 320 lbs, we must multiply 16 by 320 = 5120 ounces. Now we must divide by 12 to see how much she ate per month. 5120 divided by 12 is 426.667 or 426 and 2/3 ounces per month.
Alternatively, we can set up a proportion 1 lb / 16 ounces = 320 lb / x ounces. We cross multiply 1 times x = 320 times 15. On the left hand side we just have x and on the right hand side we get 5120. Hence, x=5120 ounces per year. To find how many she ate per month we must divide by 12 since there are 12 months in a year. So it comes out to 426 and 2/3 ounces per month.
Here are the equations: (1lb)(320lb)=(16oz)(320oz) implies 320lb=5120oz. Then divide 5120oz 12 to get how much she ate per month: 5120oz/12=426.667 ounces.

One trail through the park is 6.45 miles long. Another trail is 2.08 miles longer than the first trail. What is the combined distance of both trails
Final answer:
To find the combined distance of both trails, add the lengths of the two trails together. One trail is 6.45 miles long and the other is 2.08 miles longer.
Explanation:
To find the combined distance of both trails, we need to add the lengths of the two trails together. We know that one trail is 6.45 miles long, and the other trail is 2.08 miles longer than the first trail. So, the length of the second trail is 6.45 + 2.08 = 8.53 miles. To find the combined distance, we add the lengths of both trails: 6.45 + 8.53 = 14.98 miles.

Answer:
The true statement is: The probability that a randomly selected player on Team C is 10 years old is [tex]\frac{5}{16}[/tex].
Step-by-step explanation:
According to the table the total number of 10 years old players on Team C is 5 and the total number of all ages players (8, 9 and 10 years old) on Team C is 16, so the probability that a randomly selected player on Team C is 10 years old is 5/16.
The probability that a randomly selected player on Team C is 10 years old is 5/16.
What is Probability?This is defined as the numerical descriptions of how likely an event is to occur and is often measured in fraction.
Total number of 10 years old players on Team C = 5
Total number of all ages players (8, 9 and 10 years old) on Team C = 16
Therefore probability = 5/16
