Answer:
112.5 km
Step-by-step explanation:
The lorry needed 45 minutes to travel the remaining 0.4 of the journey and was traveling at 60 km/hr.
First, convert minutes to hours:
45 min × (1 hr / 60 min) = 0.75 hr
Now use distance equation:
distance = rate × time
0.4d = 60 × 0.75
d = 112.5
The distance between the towns is 112.5 km.

Linear function A and linear function B both have the same input values as shown below. Why will the output values for linear function A always be different than the corresponding output values for linear function B? The initial values of the two functions are different, and the rates of change of the two functions are also different. The initial values of the two functions are different, and the rates of change of the two functions are the same. The initial values of the two functions are the same, and the rates of change of the two functions are different. The initial values of the two functions are the same, and the rates of change of the two functions are also the same.
Answer:The initial values of the two functions are different, and the rates of change of the two functions are the same.
Step-by-step explanation:
The values will start out different. When you apply the rate of change, because they have the same rate of change, you don't risk them coming out with the same value if the values ended up being just right, they will always remain different.
The differences in the output values for linear function A and function B are a result of varying y-intercepts and slopes in each function. When plotted on a graph, these differences become apparent.
Explanation:The output values for linear function A and function B will differ because of variations in their respective initial values (or y-intercepts) and their rates of change (or slopes). When you plot these output values against the shared input values as a graph of y as a function of x, these differences can be seen visually. For instance, consider the linear equation y = mx + b, where m represents the slope of the line and b is the y-intercept. If function A and B have different y-intercepts or slopes, the output values will differ for the same set of input values.

Answer:
the profit will be $172
Step-by-step explanation:
The function given is:
p(x) = 2(x-9)^2 + 100
Where x is the price of the each shirt.
if each shirt is sold for $15, hen x = 15.
the profit will be:
p(15) = 2(15-9)^2 + 100
p(15) = 2(6)^2 + 100
p(15) = 2(36) + 100
p(15) = 72 + 100
p(15) = 172
So, the profit will be $172

Leonardo put a $600 ring on layaway by making a 10% down payment and agreeing to pay $65 a week. How many weeks will it take your nardo to pay off the ring?
Answer: 9 weeks
Step-by-step explanation:
Final answer:
Leonardo will take 9 weeks to fully pay off the $600 ring after making a 10% down payment and weekly payments of $65.
Explanation:
The question is asking how many weeks it will take Leonardo to pay off a ring valued at $600 with a 10% down payment and subsequent weekly payments of $65.
First, calculate the down payment Leonardo makes: 10% of $600 equals $60. Subtract the down payment from the original price to find out the remaining amount Leonardo has to pay, which is $600 - $60 = $540.
Next, divide the remaining amount by the weekly payment: $540 divided by $65 per week equals approximately 8.31, which rounds up to 9 weeks since you can't make a fraction of a payment.
Therefore, it will take Leonardo 9 full weeks to pay off the ring.

Which of the following could be the graph of this equation?
Answer: OPTION C.
Step-by-step explanation:
Given a function f(x), the range of the inverse of f(x) will be the domain of the function f(x) and the range of the domain of f(x) will be the range of the inverse function.
For example, if the point (2,1) belongs to f(x), then the point (1,2) belongs to the inverse of f(x).
Observe that in the graph of the function f(x) the point (-3,1) belongs to the function, then the point (1,-3) must belong to the inverse function.
Therefore, you need to search the option that shown the graph wich contains the point (1,-3).
Observe that the Domain f(x) is (-∞,0) then the range of the inverse function must be (-∞,0).
This is the graph of the option C.

Find the graph of the inequality y>-1/6x+1
what we do is, we simply draw the graph for its EQUALITY counterpart, namely [tex]\bf y=-\cfrac{1}{6}x+1[/tex].
then we check the regions on both sides of the graph, in this case we can check say the point (0,0) for simplicity, and
[tex]\bf y>-\cfrac{1}{6}x+1\qquad (0,0)~~ \begin{cases} x=0\\ y=0 \end{cases}\implies 0>-\cfrac{1}{6}(0)+1\implies 0>1[/tex]
now, is 0 > 1? is 0 really greater than 1? nope, is smaller, thus the area where the point (0, 0) is at is the false region, so that's the area we do NOT shade, thus the other region must be the true region and that's the one we shade.
the ">" sign means, that "y" is greater than, NOT equals to but greater, thus the values at the borderline are not included, and thus is a dashed line.

Final answer:
To construct the perpendicular bisector of AB, connect the intersections of the circles drawn from A and B with the same radius using a straightedge.
Explanation:
The student has asked what the best next step is in the construction of the perpendicular bisector of a line segment AB. The correct answer is C, which states that you should use a straightedge to draw a line segment that connects the intersections of the circles. This will create the perpendicular bisector of AB. The process involves drawing two circles with the same radius from points A and B, such that each circle goes through the other point, and then connecting the two points where the circles intersect with a straight line. This line will be the perpendicular bisector because it will be perpendicular to AB and divide it into two equal parts, hence bisecting AB.

Which matrix is the product of a 3 × 3 identity matrix and the scalar 3?
Answer:
[tex]\left[\begin{array}{ccc}3&0&0\\0&3&0\\0&0&3\end{array}\right][/tex]
Step-by-step explanation:
In order to find out the resulting matrix, we will have to multiply the identity matric and the scalar 3:
The 3x3 identity matrix is:
[tex]\left[\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}\right][/tex]
Multiplying with scalar 3:
[tex]3\left[\begin{array}{ccc}1&0&0\\0&1&0\\0&0&1\end{array}\right][/tex]
The scalar will be multiplied by each element of the matrix.
Multiplying zeros with scalar 3 will give us zero. So the resulting matrix will be:
[tex]\left[\begin{array}{ccc}3*1&0&0\\0&3*1&0\\0&0&3*1\end{array}\right] = \left[\begin{array}{ccc}3&0&0\\0&3&0\\0&0&3\end{array}\right][/tex]
So the resultant matrix will be a scalar matrix with 3 at diagonal positions..

C. 7x^2 -2x-6
D. 7x^2- 8x-6
Answer:
Let's simplify step-by-step.
7x^2−3x+5x−6
=7x^2+−3x+5x+−6
Combine Like Terms:
=7x^2+−3x+5x+−6
=(7x^2+2x+−6 )
Answer:
=7x^2+2x−6
Final answer:
The sum of (7x² - 3x) and (5x - 6) is found by combining like terms, resulting in 7x² + 2x - 6, which is option C.
Explanation:
To solve the algebraic addition (7x²-3x) + (5x-6), you need to combine like terms.
First, identify and group like terms from both expressions. Like terms are those that have the same variable raised to the same power.
Combine the coefficients (numerical values) for each group of like terms.
Now, let's go through each step:
For the x2 terms: 7x2 (from the first polynomial) has no like term in the second polynomial, so it remains as is.
For the x terms: -3x (from the first polynomial) and +5x (from the second polynomial) combine to give 2x.
Lastly, the constant terms: -6 (from the second polynomial) also has no like term in the first polynomial, so it remains as is.
By combining these, the result is 7x² + 2x - 6, which corresponds to option C.
Which is the better buy?
A. 1,323 ounces of topsoil for $410.13
B. 8 pounds of topsoil for $78.08
Answer:
Option. A
Step-by-step explanation:
Covert Ounces to Pounds, or vice versa, I went with pounds.
1323 ounces = 82 pounds.
find the pound to dollar rate
A; 82 ÷ 410.13 = about 5
B; 8 ÷ 78.08 = 9.76
The better buy is A. 1,323 ounces of topsoil for $410.13.
To determine which is the better buy, we need to calculate the price per ounce for both options and then compare them.
First, let's calculate the price per ounce for option A:
1,323 ounces of topsoil for $410.13.
Price per ounce for A = $410.13 / 1,323 ounces.
Now, let's calculate the price per ounce for option B:
Since 1 pound is equal to 16 ounces, 8 pounds of topsoil is equal to
8 × 16 = 128 ounces.
8 pounds of topsoil for $78.08.
Price per ounce for B = $78.08 / 128 ounces.
Next, we compare the price per ounce for both options:
Price per ounce for A = $410.13 / 1,323 ounces $0.310 / ounce.
Price per ounce for B = $78.08 / 128 ounces $0.609 / ounce.
Since the price per ounce for option A ($0.310) is less than the price per ounce for option B ($0.609), option A is the better buy. The customer gets more topsoil for their money with option A.

The IPhone 7 costs about $220 for Apple to make, but they cost about $700 in stores. What is the markup percentage of the IPhone 7? (Round to the nearest
Answer:
The markup percentage of the IPhone 7 is $218.18%.
Step-by-step explanation:
The IPhone 7 costs for Apple to make = $220
The cost in stores = $700
The difference between costing price and selling price = 700 -220 = $480
The markup percentage of the IPhone 7 = [tex]\frac{480}{220}[/tex] × 100
= $218.18
The markup percentage of the IPhone 7 is $218.18%.
The markup percentage of an iPhone 7 is calculated by finding the difference between the selling and cost price, dividing this by the cost price and then multiplying by 100. According to these steps, the markup percentage of the iPhone 7 is approximately 218%.
Explanation:The markup percentage indicates how much an item's price has increased from its original cost to make. It is calculated by finding the difference between the selling price and the cost to make, then dividing that by the cost to make, and then multiplying it by 100 to get the percentage.
To calculate the markup percentage of the iPhone 7:
Determine the difference between the selling price and the cost price. In this case, $700 (selling price) - $220 (cost price) = $480. Now divide the difference by the cost to make. $480 / $220 = 2.18. Finally, multiply by 100 to get the percentage. 2.18 * 100 = 218% (rounded to the nearest whole number).
Therefore, the markup percentage of the iPhone 7 is 218%.
