Together teammates pedro and ricky got 2685 base hits last season. Pedro had 275 more than ricky. How many hits did each player have?
Answers
Pedro = 1,480 hits
Ricky = 1,205 hits
Explanation:
2685(total) - 275(extra hits Pedro had) = 2,410
Take 2,410 and divide by 2 (Pedro and Ricky) = 1,205
1,205 (Ricky) + 1,205+275(Pedro)

A transformation of rectangle ABCD results in rectangle A’B’C’D
Which transformation maps the pre-image to the image
Answers
In a dilation, the size of the object can be changed while keeping its shape, which is the case in this scenario.
A transformation of rectangle ABCD results in rectangle A’B’C’D. We need to identify which transformation maps the pre-image to the image.Two-dimensional transformations can be classified into four main categories; translations, reflections, rotations, and dilations. We will evaluate each of these to determine which of them maps the pre-image to the image.
TranslationsA translation is a transformation that moves an object in a straight line without changing its shape or orientation. It involves moving an object by a fixed distance in a particular direction. The image is congruent to the pre-image. This transformation does not result in a rectangle ABCD being transformed to A’B’C’D.
It results in a rectangle that has the same size and shape as the pre-image being moved to a different location.ReflectionsA reflection is a transformation that flips an object across a line without changing its shape or orientation. A reflection through a line known as the x-axis, or the y-axis results in a mirror image of the object.
This transformation does not result in a rectangle ABCD being transformed to A’B’C’D.RotationsA rotation is a transformation that turns an object about a fixed point. The fixed point is known as the center of rotation. The angle through which the object is rotated is known as the angle of rotation. A rotation does not change the size or shape of an object, but it changes its orientation. This transformation does not result in a rectangle ABCD being transformed to A’B’C’D.
DilationsA dilation is a transformation that changes the size of an object. The size change is described by a scale factor. The scale factor is greater than 1 for an enlargement and between 0 and 1 for a reduction. The center of dilation is the point about which the object is enlarged or reduced. This transformation does not result in a rectangle ABCD being transformed to A’B’C’D.After evaluating each of the four types of transformations, we can conclude that the transformation that maps the pre-image rectangle ABCD to the image rectangle A’B’C’D is a dilation.

A large trucking company wants to estimate the proportion of its tracker truck population with refrigerated carrier capacity. A random sample of 200 tracker trucks is taken and 30% of the sample have refrigerated carrier capacity. The 95% confidence interval to estimate the population proportion is _______.
Answers
Answer:
The 95% confidence interval to estimate the population proportion is (0.2365, 0.3635).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of \(\pi\), and a confidence level of \(1-\alpha\), we have the following confidence interval of proportions.
\(\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}\)
In which
z is the zscore that has a pvalue of \(1 - \frac{\alpha}{2}\).
For this problem, we have that:
\(n = 200, \pi = 0.3\)
95% confidence level
So \(\alpha = 0.05\), z is the value of Z that has a pvalue of \(1 - \frac{0.05}{2} = 0.975\), so \(Z = 1.96\).
The lower limit of this interval is:
\(\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3 - 1.96\sqrt{\frac{0.3*0.7}{200}} = 0.2365\)
The upper limit of this interval is:
\(\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.3 + 1.96\sqrt{\frac{0.3*0.7}{200}} = 0.3635\)
The 95% confidence interval to estimate the population proportion is (0.2365, 0.3635).

G(8.3,-1.4) is the midpoint between B(x,y) and L(-5.9,8). Find the coordinates of B
Answers
The coordinates of B is (22.5, -3.6)
How to find the coordinates of B?The points are given as:
G = (8.3,-1.4)
B = (x,y)
L = (-5.9,8).
The midpoint is calculated as:
G = 0.5 * (x1 + x2, y1 + y2)
So, we have:
(8.3,-1.4) = 0.5 * (x - 5.9, y + 0.8)
This gives
(16.6,-2.8) = (x - 5.9, y + 0.8)
Solve for x and y
x - 5.9 = 16.6
y + 0.8 = -2.8
Evaluate
x = 22.5
y = -3.6
Hence, the coordinates of B is (22.5, -3.6)

A girl is currently 5 years older than her younger brother and 3 years younger than her older brother. Two years from the current time, the product of the ages of the brothers will be twelve times the age of the girl. What is the current age of the older brother ?
Answers
The current age of the older brother is 16 years while that of the girl is 13 years.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the girl age, y the younger brother age and z the older brother age. Hence:
x = y + 5
y = x - 5 (1)
Also:
z = x + 3 (2)
In two years time:
(y + 2)(z + 2) = 12(x + 2)
(x - 5 + 2)(x + 3 + 2) = 12(x + 2)
(x - 3)(x + 5) = 12(x + 2)
x² + 2x - 15 = 12x + 24
x² - 10x - 39 = 0
x = -3 and x = 13
Age must be positive, hence x = 13
z = x + 3 = 13 + 3 = 16 years
The current age of the older brother is 16 years while that of the girl is 13 years.

A man decides to take out $70 per month from his savings account. After 63 months, he has $2720 in his account. Identify the slope and point, then write a linear equation in point-slope form which models the amount in the savings account in terms of the number of months.
Answers
Answer:
the Point are: ( 63, 2720 )
Slope is : - 70
linear equation in point-slope : y = 7130 - 70x
Step-by-step explanation:
given the data in the question;
let x represent number of months he is taking money from his account
so
y = 70x + 2720
so total amount in his account will be;
⇒ 70×63 + 2720
= $7,130
for each month, ( say x in number) he takes out $70,
let y be amount in account at (x) month, so;
y = 7130 - 70x
the Point are: ( 63, 2720 )
Slope is : - 70

5^(2x-1)+5^(x+1)=250
how do you solve?

Answers
Answer:
x = 2
Step-by-step explanation:
Exponential Equations
Solve:
\(5^{2x-1}+5^{x+1}=250\)
Separate each exponential:
\(5^{2x}5^{-1}+5^{x}5^{1}=250\)
Operating:
\(\displaystyle \frac{5^{2x}}{5}+5^{x}5=250\)
Multiplying by 5:
\(5^{2x}+25\cdot5^x=1250\)
Rearranging:
\(5^{2x}+25\cdot5^x-1250=0\)
Recall that:
\(5^{2x}=(5^{x})^2\)
\((5^{x})^2+25\cdot5^x-1250=0\)
Calling
\(y=5^{x}:\)
\(y^2+25y-1250=0\)
Factoring:
\((y-25)(y+50)=0\)
There are two possible solutions:
y=25
y=-50
Since
\(y=5^{x}\)
y cannot be negative, thus:
\(5^{x}=25=5^2\)
The solution is:

Clarence walks 3.1 miles around Lake Johnson every day for five days.
If it takes him a total of 6 hours to walk the 15.5 miles, what is his
average time per day?
minutes per day.
Answers
Answer:
Average time per day = 1.2 hours per day
Average time per day = 72 minutes per day
Step-by-step explanation:
To find Clarence's average time per day, we need to divide the total time he takes to walk the 15.5 miles by the number of days he walks, which is five.
Let's calculate his average time per day:
Average time per day = Total time / Number of days
Since Clarence takes a total of 6 hours to walk the 15.5 miles, we'll divide 6 by 5 to find his average time per day:
Average time per day = 6 hours / 5
Average time per day = 1.2 hours per day
To convert hours to minutes, we'll multiply the average time per day by 60:
Average time per day = 1.2 hours * 60 minutes
Average time per day = 72 minutes per day
Therefore, Clarence's average time per day is 72 minutes.

A salesperson is paid an 8.25% commission on sales when the invoice is
pald. This month's paid invoices totaled $49,900. What is the salesperson's
commission for this month?
Answers
Answer:
The salesperson's commission for this month is: $4116.75
Step-by-step explanation:
Given
Current month's paid invoice's total = $49,900
Commission = 8.25% = 0.0825
To determine
What is the salesperson's commission for this month?
The salesperson's commission for this month can be determined by multiplying the invoice's total i.e. $49,900 with the commission percentage of 0.0825.
Thus,
Commission amount = 49,900 × 8.25%
= 49,900 × 0.0825 ∵ 8.25% = 0.0825
= $4116.75
Therefore, the salesperson's commission for this month is: $4116.75

also:
length-6= 2×width
length=2width +6
now you can put the length we found, in the second equation:
54-width=2width+6
54-6=2width+width
48=3width
width=16
now do the exact same thing with one of the equations we created in the beginning.

or this:

as the 1st one is simpler, I use that:

To solve the equation -3 + m = 9, we can isolate the variable m by moving the constant term -3 to the other side of the equation.

To move -3 to the other side, we can add 3 to both sides of the equation:
-3 + 3 + m = 9 + 3
Simplifying, we have:
m = 12
Therefore, the value of m that satisfies the equation -3 + m = 9 is m = 12.
