A baseball team has a goal of hitting more than 84 home runs this season. They average 7 home runs each game and have already hit 35 home runs so far. How many more games, x, will it take the baseball team to reach its home run hitting goal if they continue to average 7 home runs per game?
Final answer:
The baseball team needs to play 7 more games to exceed its goal of 84 home runs, based on their current average of 7 home runs per game.
Explanation:
The baseball team has hit 35 home runs and wants to hit more than 84. To find how many more games it will take, we first calculate the total number of home runs needed to surpass 84, which is 84 - 35 = 49 home runs. Since the team averages 7 home runs per game, we divide the remaining home runs needed by the average per game to find x, the number of games needed: 49 home runs / 7 home runs per game = 7 games.
Therefore, the baseball team needs to play 7 more games to reach its goal, assuming the average stays constant.

A bouncing ball reaches a height of 27 feet at its first peak, 18 feet at its second peak, and 12 feet at its third peak. Describe how a sequence can be used to determine the height of the ball when it reaches its fourth peak.
Answer:
so on the fourth bounce the ball will reach a height of 8 feet
Step-by-step explanation:
There is a common ratio of 2/3 between the height of the ball at each bounce so the bounce height from a geometric sequence 27,18,12 two-thirds of 12 is 8 so on the fourth bounce the ball will reach a height of 8 feet

It takes 40 min for a bus to travel the 36 miles from Framingham to Worcester. A car traveling from Worcester to Framingham moves 1.5 times as fast as the bus. If the car and the bus start moving towards each other simultaneously, after how many minutes will they meet?
The velocity of the bus is:
velocity (bus) = 36 miles / 40 min
velocity (bus) = 0.9 miles / min
Since the car is 1.5 times faster, so the velocity of the car is:
velocity (car) = 1.5 * 0.9 miles / min
velocity (car) = 1.35 miles / min
At the meeting point, the sum of the distance is equal to 36 miles. Therefore:
1.35 t + 0.9 t = 36
2.25 t = 36
t = 16 min
So they will meet after 16 minutes.
You have a map where indy and fort wayne are 13 centimeter apart. kokomo and indy are 6.5 cm apart on the map. if you know that indy and fort wayne are actually 120 miles apart, how far apart would indy and kokomo be in real life? express your answer rounded to the nearest tenth of a mile
The distance between Indy and Kokomo be in real life is given by the proportion A = 60 miles
What is Proportion?The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
The proportional equation is given as y ∝ x
And , y = kx where k is the proportionality constant
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Given data ,
Let the proportion be represented as A
Now , the value of A is
Let the distance between Indy and Fort Wayne in map = 13 cm
Let the distance between Indy and Fort Wayne in real = 120 miles
And , let the distance between Kokomo and Indy map = 6.5 cm
So , the proportion is
120 / 13 = A / 6.5
Multiply by 6.5 on both sides , we get
A = 120 / 2
A = 60 miles

Show how to multiply 6 x 298 using friendly numbers and then using properties and mental math.Write about which method you like better and why
Final answer:
To multiply 6 x 298 using friendly numbers, you multiply 6 by 300 and then subtract 12, getting 1788. Using properties and mental math, you break 298 into 200 + 90 + 8, multiply each by 6, and add the results together to get the same answer, 1788. The second method is preferred for its accuracy and reinforcement of the associative property.
Explanation:
To multiply 6 x 298 using friendly numbers, we can adjust 298 to a number that is easier to multiply, such as 300. This method involves approximation for ease of calculation. Here's how it would look:
First, multiply 6 by 300 to get 1800 (since 6 x 3 = 18, and then we add two zeros because we're multiplying by 300).Since we multiplied by 2 more than the original number (298 + 2 = 300), we subtract 2 times 6 from the result (which is 12) to correct for our approximation.Therefore, the final result is 1800 - 12 = 1788.Using properties and mental math, we can use the distributive property to break 298 into more manageable numbers. Here's the step-by-step process:
Break 298 into 200 + 90 + 8.Multiply each part by 6: (6 x 200) + (6 x 90) + (6 x 8).Calculate each multiplication separately: 1200 + 540 + 48.Add the results together: 1200 + 540 + 48 = 1788.I prefer the second method because it guarantees accuracy and still takes advantage of the associative property to simplify calculations without approximations. Additionally, this type of mental math helps to reinforce an understanding of multiplication as a series of simpler, added-together parts.

which is longer 84 inches or 12 feet
which is the longer length 29ft or 9 yards
To compare 29 feet and 9 yards, convert 9 yards to feet, which equals 27 feet. Since 29 feet is greater than 27 feet, 29 feet is longer.
To determine which length is longer between 29 feet and 9 yards, we need to convert one of the measurements to the same unit. We know that 1 yard is equal to 3 feet. Therefore, to convert 9 yards to feet:
9 yards x 3 feet/yard = 27 feetComparing the two lengths, 29 feet is longer than 27 feet.
Thus, 29 feet is the longer length.

Given that the points (-1, 6), (3, 6), (3, 1), and (-1, 1) are vertices of a rectangle, how much shorter is the width than the length?
Answer:
1 unit shorter
Step-by-step explanation:
By plotting the given points in the coordinate plane,
We get a rectangle ABCD having vertices,
A(-1,6), B (3,6), C (3,1), D (-1,1)
By the distance formula,
Shorter side or width of the rectangle,
[tex]AB=\sqrt{(3-(-1))^2+(6-6)^2}=\sqrt{4^2+0}=4\text{ unit}[/tex]
Longer side or length of the rectangle,
[tex]BC=\sqrt{(3-3)^2+(1-6)^2}=\sqrt{5^2}=5\text{ unit}[/tex]
The difference between length and width,
[tex]BC - AB = 5 - 4 = 1\text{ unit}[/tex]
Hence, the width of rectangle is 1 unit less than the length.

Find the solution to the linear system of differential equations {x′y′==−5x+3y−18x+10y satisfying the initial conditions x(0)=4 and y(0)=11
The problem given is a linear system of differential equations with initial conditions, but the system is not properly defined and appears to have a typo. Normally, such a system would be in the form x' = ax + by and y' = cx + dy, with initial conditions that would determine the particular solution.
Explanation:This question is about solving a linear system of differential equations with initial conditions, specifically the system {x′y′==−5x+3y−18x+10y with the initial conditions x(0)=4 and y(0)=11. However, there seems to be a typo, as the system is not properly defined and doesn't make sense as written. Under normal conditions, such a system would be in the form x' = ax + by and y' = cx + dy, where a,b,c,d are constants and x' and y' are the derivatives of x and y respectively.
Additionally, the initial conditions x(0)=4 and y(0)=11 would serve to define the particular solution for the system of differential equations. Correcting and resolving such typos would be the first step in progressing towards a solution.

Kwan's parents bought a home for $50,000 in 1997 just as real estate values in the area started to rise quickly. Each year, their house was worth more until they sold the home for $309,587. Model the growth of the home's value from 1997 to 2007 with both linear and an exponential equation. Graph the two models below.
A. First let us start with the linear model.
The equation is in the form of y = m x + b
Calculating for the slope m:
m = (309,587 – 50,000) / (2007 – 1997)
m = 25,958.7
Subsituting:
y = 25,958.7 x + b
Taking x = 1997, y = 50,000. Solve for b:
50,000 = 25,958.7 (1997) + b
b = -51,789,523.9
The complete equation is therefore:
y = 25,958.7 x - 51,789,523.9
B. The exponential model has the following form:
y = a b^x
where a and b are constants
Taking x1= 1997, y1 = 50,000; x2 = 2007, y2 = 309,587
50,000 = a b^1997
309,587 = a b^2007
Combining in terms of a:
50,000 / b^1997 = 309,587 / b^2007
b^2007 / b^1997 = 309,587 / 50,000
b^10 = 6.19174
b = 1.2
Substituting:
y = a 1.2^x
Solving for a:
50,000 = a 1.2^1997
a = 3.75 x 10^-154
The complete equation is:
y = 3.75 x 10^-154 * 1.2^x
