Answer:
David earns $1,020 a week, and his weekly profit is $670.
Step-by-step explanation:
Since David walks six dogs per day, and each dog is $20, he earns a total of $120 per day from those six dogs. Also, knowing that he walks the six dogs five days a week, he earns $600 from walking the six dogs for five days per week alone. Using this same logic for the three dogs he walks seven days a week, we can conclude that he gets $60 from walking those three dogs. Knowing he walks those three dogs seven days a week, he gets $420 from walking those three dogs. Combining the totals gives us $1,020, the amount of money he earns per week. Since his weekly expenses are $350, we subtract that from $1,020 to get his weekly profit: $670.
the number of people who own computers has increased 23.2% annually since 1990. if half a million people owned a computer in 1990 predict how many people will own a computer in 2015
The no. of people own computer in 2015 are 92.0953 million.
What is compound interest?The interest charged on a loan or deposit is known as compound interest. In our day-to-day lives, it is the concept we use the most. The amount's compound interest is based on both the principal and the interest earned over time. This is the primary distinction between simple and compound interest.
Given annually increase rate of computers = R = 23.2%
people own computer in 1990 = 1/2 million = 0.5 million
let no. of people own computer in 2015 be x
compound interest for annually increase in rate is p[tex](1 + R/100)^{t}[/tex]
where t = time and R = rate
Time = 2015 - 1990 = 25 years
x = 0.5(1 + 23.2/100)²⁵
x = 0.5(1.232)²⁵
x = 0.5 × 184.1906
x = 92.0953 million
Hence 92.0953 million people own computer in 2015.

10. Which transformations result in a preimage and image with opposite orientations?
1 point
Dilations only
Translations and rotations
Rotations and reflections
Reflections and glide reflections
In geometry, reflections and glide reflections are transformations that result in a preimage and an image with opposite orientations. This happens because a reflection flips an object over a line, creating a mirror image with reverse orientation. A glide reflection combines a translation and a reflection, also leading to opposite orientation.
Explanation:In mathematics, particularly in geometry, when we talk about a preimage and an image, we refer to the original shape and the shape after transformation respectively. The transformation that results in a preimage and image with opposite orientations is reflections and glide reflections. A reflection is a transformation that flips a figure over a line, thus turning it into its mirror image. This reverses the orientation of the figure. A glide reflection involves a translation (or glide) followed by a reflection. Again, the result will have an orientation opposite to the original (or preimage).

Which statement describes a parallelogram that must be a square?
A. A parallelogram with a pair of congruent consecutive sides and diagonals that bisect each other.
B. A parallelogram with a pair of congruent consecutive sides and diagonals that are congruent.
C. A parallelogram with a right angle and diagonals that are congruent
D. A parallelogram with diagonals that bisect each other.
Answer: B. A parallelogram with a pair of congruent consecutive sides and diagonals that are congruent.
Step-by-step explanation:
We know that a parallelogram is a quadrilateral having congruent opposite sides and its diagonals bisect each other.
A square is a kind of parallelogram having all its consecutive sides equal and both diagonals congruent to each other.
Its all 4 angles are right angle.
let's check all the statements :
A. A parallelogram with a pair of congruent consecutive sides and diagonals that bisect each other.
→It can be rhombus ∵ it also has same characteristics.
B. A parallelogram with a pair of congruent consecutive sides and diagonals that are congruent.
→ It only occurs in square.
C. A parallelogram with a right angle and diagonals that are congruent .
→ it can be a rectangle ∵ it has all its angles right angle and diagonals are congruent.
D. A parallelogram with diagonals that bisect each other.
→ It is the basic property of parallelogram , it can describe a rhombus or rectangle both.
The statement that must be true is (b) A parallelogram with a pair of congruent consecutive sides and diagonals that are congruent.
A parallelogram has parallel and congruent opposite sides
However, the following must be true about parallelograms that can be regarded as squares:
There are congruent consecutive sidesThe diagonals are congruentHence, the true statement is (b)

How does the graph of g(x) = 1/x+4-6 compare to the graph of the parent function f(x)=1/x ?
We are given a parent function f(x) as:
[tex]f(x)=\dfrac{1}{x}[/tex]
and the transformed function g(x) is given by:
[tex]g(x)=\dfrac{1}{x+4}-6[/tex]
We know that the transformation of the type:
f(x) → f(x+a)
is either a shift a units to the left or to the right depending whether a is positive or negative respectively.
Also, the transformation of the type:
f(x) → f(x)+a
is the shift of the function f(x) either upward or downward depending on whether x is positive or negative respectively.
Here the function g(x) is:
[tex]g(x)=f(x+4)-6[/tex]
This means that the function g(x) is a shift of the function f(x) 4 units to the left and then it is translated 6 units downward.
Also we may see by the graph.
If a car rental costs $35 per day plus $0.79 per mile, and you are traveling for 4 days, 389 miles, how much is the total rental?
Answer:
Total rent costing for traveling for 4 days, 389 miles is $447.31
Step-by-step explanation:
Given : a car rental costs $35 per day plus $0.79 per mile.
We have to find the total rent costing for traveling for 4 days, 389 miles.
Since, Cost of car rent per day is $35
Thus, Cost of car rent for 4 days is $ 35 × 4 = $140
Also, Cost of car rent per miles is $0.79
Thus, Cost of car rent for 389 miles is $ 0.79 × 389 = $307.31
Thus, total car rental cost = Cost of car rent for 4 days + Cost of car rent for 389 miles.
Total car rental cost = $140 + $307.31
Total car rental cost = $447.31
Thus, total rent costing for traveling for 4 days, 389 miles is $447.31

A business owes $8000 on a loan. Every month, the business pays 12 of the amount remaining on the loan.
How much will the business pay in the sixth month?
The business will pay $506.99 on the loan in the sixth month, after making monthly payments of 12% of the remaining balance on an $8000 loan.
Explanation:To determine how much the business will pay in the sixth month on a loan where they pay off 12% of the remaining balance each month, we need to use a decay formula. This is a type of exponential decay since the amount owed is decreasing by a fixed percentage each month. The formula to find the remaining balance after each payment is:
Balance after n payments = Initial amount * (1 - rate)^n
Starting with an initial loan amount of $8000 and a monthly payment rate of 12% (or 0.12 in decimal form), we calculate the remaining balance each month until the sixth month:
Month 1: 8000 * (1 - 0.12) = 8000 * 0.88 = $7040 remainingMonth 2: 7040 * 0.88 = $6195.20 remainingMonth 3: 6195.20 * 0.88 = $5455.78 remainingMonth 4: 5455.78 * 0.88 = $4801.09 remainingMonth 5: 4801.09 * 0.88 = $4224.96 remainingMonth 6: 4224.96 * 0.88 = $3717.97 remainingNow we can find out how much will be paid in the sixth month by calculating 12% of the balance at the end of the fifth month:
Sixth month payment = 12% of 4224.96
Sixth month payment = 0.12 * 4224.96
Sixth month payment = $506.99
The business will pay $506.99 in the sixth month.
