The scale of a map says 4cm represents 5km what distance on the map (in centimeters) represents an actual distance of 4 km?
Answer:
3.2 cm on the map (in centimeters) represents an actual distance of 4 km
Step-by-step explanation:
The scale of a map says 4cm represents 5km
We are supposed to find what distance on the map (in centimeters) represents an actual distance of 4 km
5 km = 4 cm
1 km = [tex]\frac{4}{5} cm[/tex]
4 km = [tex]\frac{4}{5} \times 4 cm[/tex]
4 km = [tex]3.2 cm[/tex]
Hence 3.2 cm on the map (in centimeters) represents an actual distance of 4 km
Using the discriminant, determine the number of real solutions.
2x^2+7x-15=0
- no real solutions
-one real solution
-two real solutions
Answer:
Since discriminant is positive, therefore, the given quadratic equation has two real solutions. Correct answer is the last option.
Step-by-step explanation:
We have been given a quadratic equation and we need to figure out the number of real solutions of the equation.
[tex]2x^{2}+7x-15=0[/tex]
We know that discriminant of a general quadratic equation [tex]ax^{2}+bx+c=0[/tex] is given by [tex]D=b^{2}-4ac[/tex]
For the given quadratic equation [tex]2x^{2}+7x-15=0[/tex], we have [tex]a=2,b=7,c=-15[/tex]. Upon substituting these values in the formula for discriminant, we get:
[tex]D=7^{2}-4(2)(-15)[/tex]
[tex]D=49+120[/tex]
[tex]D=169[/tex]
Since discriminant is a positive number, therefore, the given quadratic equation has two real solutions. Hence, the last option is the correct answer.

Step-by-step explanation:
In △XYZ, XY=XZ
It is isosceles triangle whose equal sides are XY=XZ
We are given,
XY=2a
YZ=3a+1
XZ=5a-12
XY=XZ
So, 2a=5a-12
Solve for a,
2a-5a=-12
-3a=-12
a=4
Now we put a=4 into XY=2a
So, XY=2(4)=8
Answer:
1.In △XYZ, XY=XZ.
We have to Find the length of XY of △XYZ if XY=2a, YZ=3a+1, and XZ=5a−12.
Now, X Y=X Z [given]

A container holds 80,000 ounces of water. There is a small leak in the the container. Every 96 minutes, 1.9 ounces of water leak out. What is the total change in water after 8 hours?
It is known that 60 minutes equals 1 hour.
Therefore, the first thing we do to solve the problem is to calculate how many hours are equivalent to 96 minutes.
For that we calculate:
[tex]96 minutes * \frac{1 hour}{60minutes}=\frac{96}{60}=1.6hours\\[/tex]
Thus:
96 minutes = 1.6 hours.
1.9 ounces of water are lost every 1.6 hours.
Therefore, in 8 hours the amount of water lost is:
[tex]\frac{8hours}{1.6hours}*1.9 = 9.5\\[/tex] ounces of water
After 8 hours, 9.5 ounces of water are lost
Therefore, the amount of water left in the tank after 8 hours is:
[tex]80 000-9.5=79990.5[/tex] ounces

Question 1:
Shop A trainers normal price= £85
[tex]\frac{1}{3}[/tex] is off so it becomes [tex]\frac{1}{3}\times85=28.33[/tex]
So price becomes: [tex]85-28.33=56.67[/tex]
Shop B trainers normal price= £80
30% is off so it becomes: [tex]\frac{30}{100}\times80=24[/tex]
So price becomes: [tex]80-24=56[/tex]
So, Shop B has cheaper trainers.
Question 2:
In a sale all items are reduced by = 30%
On the final day the sale price are reduced by = 20%
On the day before the last day of the sale, the price of the sofa was [tex]0.7\times290=203[/tex]
As given, on the last day of the sale, the price was again reduced to 80% of the price the day before, so price becomes: [tex]0.8\times203=162.40[/tex]
Hence the price was £162.40

Part A: What is the scale factor of the dilation that transforms triangle PQR to triangle P'Q'R'? Explain your answer. (4 points)
Part B: Write the coordinates of triangle P"Q"R" obtained after P'Q'R' is reflected about the y-axis. (4 points)
Part C: Are the two triangles PQR and P''Q''R'' congruent? Explain your answer. (2 points)
ANSWER TO QUESTION 1.
We plot the points:
[tex]P(8,0)[/tex]
[tex]Q(6,2)[/tex]
and
[tex]R(-2,-4)[/tex]
We plot the image triangle also with the points,
[tex]P'(4,0)[/tex]
[tex]Q'(3,1)[/tex]
and
[tex]R(-1,-2)[/tex]
See graph in attachment.
ANSWER TO QUESTION 2.
The scale factor is the ratio of the image length to the object length.
[tex]Scale\: factor=\frac{|P'Q'|}{|PQ|}[/tex].
We need to use the distance formula to determine the two lengths.
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
[tex]|P'Q'|=\sqrt{(3-4)^2+(1-0)^2}[/tex]
[tex]|P'Q'|=\sqrt{(-1)^2+(1)^2}[/tex]
[tex]|P'Q'|=\sqrt{1+1}[/tex]
[tex]|P'Q'|=\sqrt{2}[/tex]
[tex]|PQ|=\sqrt{(6-8)^2+(2-0)^2}[/tex]
[tex]|PQ|=\sqrt{(-2)^2+(2)^2}[/tex]
[tex]|PQ|=\sqrt{4+4}[/tex]
[tex]|PQ|=\sqrt{8}[/tex]
[tex]|PQ|=2\sqrt{2}[/tex]
Therefore the scale factor of the dilation is
[tex]Scale\: factor=\frac{\sqrt{2}}{2\sqrt{2}}[/tex].
[tex]Scale\: factor=\frac{1}{2}[/tex].
ANSWER TO QUESTION 3
For a reflection in the y-axis we negate the x-coordinates. That means we are using the y-axis as our mirror line. The mapping is given as follows:
[tex]P'(4,0)\rightarrow P''(-4,0)[/tex]
[tex]Q'(3,1)\rightarrow Q''(-3,1)[/tex]
and
[tex]R(-1,-2)\rightarrow R''(1,-2)[/tex]
ANSWER TO QUESTION 4
We can see from the diagram that, PQR is bigger than P"Q"R".
The reason is that PQR was reduced by scale factor of half and then reflected in the y-axis to obtain P"Q"R".
Since dilation is not a rigid motion, the two triangles PQR and P''Q''R" are not equal in all respect, therefore they are not congruent.

The Yu family and the Sainz family went on vacation together and each family leased a car. The leasing company charged a flat rental fee for the week, plus a charge for each mile driven. The Yu's drove 222 miles; their car cost $110.30 for the week. The Sainz's drove 147 miles; their car cost $99.05. What is the linear equation that represents the cost of a rental car? Round to the nearest hundredth
Answer:
y = 0.15x+77 is the equation linear connecting total cost y and miles driven x
Step-by-step explanation:
Given that the leasing company charged a flat rental fee for the week, plus a charge for each mile driven.
Let flat rental fee be c and cost per mile driven = m and miles driven = x
Total cost =y
Then y = mx+C is the linear equation.
to find m and c, we use the fact that y =110.30 when x = 222
i.e. 110.30 = c+222x
and similarly 99.05 = c+147x
Subtract to eliminate c
11.25 = 75 x
0.15 =x
Substitute in I equation
110.30 = c+222(0.15)
c = 77
Hence y = 0.15x+77 is the equation linear connecting total cost y and miles driven x
Answer:
y = 0.15x+77

The function "g" is defined as g(x)=5x+a, where "a" is a constant. If g(4)=31, what is the value of "a"?
To find the constant 'a' in the function g(x) = 5x + a, you can substitute the known values into the function. Here, it leads us to the equation 5*4 + a = 31. Solving this equation gives 'a' = 11.
Explanation:The question gives us the value of g(4) and asks us to find the constant 'a' in the function g(x) = 5x + a.
To solve for 'a', we can substitute the known values into the equation. We know that g(4) = 31, and the function g(x) is defined as 5x + a. Therefore, we replace 'x' with 4 in the function. This gives us 5*4 + a = 31.
Solving this equation, we find that 20 + a = 31. By subtracting 20 from both sides of the equation, we can solve for 'a', giving us 'a' = 31 - 20 = 11.

A total of 676 tickets were sold for the school play. They were either adult tickets or student tickets. There were 74 fewer student tickets sold than adult tickets. How many adult tickets were sold?
There were 375 adult tickets sold.
Explanation:This question involves a concept in basic algebra. Let's denote the number of adult tickets as A and the number student tickets as S. From the problem, we know that the total number of tickets sold is 676, so A+S=676. The problem also tells us that there were 74 fewer student tickets sold than adult tickets, so we know that S=A-74.
We can substitute the value of S from the second equation into the first equation which gives us A+(A-74)=676. By solving this equation we find that A=375, so there were 375 adult tickets sold.
Let's denote the number of adult tickets sold as x. Since there were 74 fewer student tickets sold, the number of student tickets sold is x - 74. The total number of tickets sold is the sum of the adult and student tickets, which is 676.
Therefore, we can write the equation:
x + (x - 74) = 676
Simplifying the equation:
2x - 74 = 676
Adding 74 to both sides:
2x = 750
Dividing by 2:
x = 375
So, 375 adult tickets were sold.

I am F years old and my brother is B years older.What was the difference of our ages two year ago?
Answer:
So the difference of ages 2 years ago is [tex]B[/tex] years.
Step-by-step explanation:
The difference of age between me and my brother will not change whether we go back in time or forward in time, it will always be the same difference as of now. In this case it is B years. To further prove this we can do a calculation as below,
If I am F years old and brother is [tex]B[/tex] years older, the age of my brother is,
Age of the brother = [tex]F+B[/tex]
Age of me 2 years ago = [tex]F-2[/tex]
Age of my brother 2 years ago = [tex]F+B-2[/tex]
So the difference of ages 2 years ago can be calculated as,
Age of my brother 2 years ago - Age of me 2 years ago

A bird is flying 43 5/9 feet above the sea. A fish is swimming 23 2/3 feet below the surface of the sea, directly below the bird. What is the vertical distance between the bird and the fish?
Answer:
67.23
Step-by-step explanation:
Please refer to the attachment photo for explanation
Final answer:
The vertical distance between the bird and the fish is 67 2/9 feet.
Explanation:
To calculate the vertical distance between the bird and the fish, we need to add the distance the bird is flying above the sea to the distance the fish is swimming below the sea.
The bird is flying at a height of 43 5/9 feet above the sea, which can be converted to an improper fraction for easier calculation:
43 5/9 = (43×9 + 5)/9 = 392/9 feet
The fish is swimming at 23 2/3 feet below the surface of the sea, which also can be converted to an improper fraction:
23 2/3 = (23×3 + 2)/3 = 71/3 feet
To find the total distance, we add these two fractions:
392/9 (bird's height) + 71/3 (fish's depth)To add these fractions, we need a common denominator. The lowest common denominator for 9 and 3 is 9.
392/9 + 71/3×3/3 = 392/9 + 213/9Total distance = 392/9 + 213/9 = 605/9 feetWhen we convert the improper fraction back to a mixed number, we get:
605/9 feet = 67 2/9 feetSo, the vertical distance between the bird and the fish is 67 2/9 feet.
use the distributive property to write an expression equivalent to 5×(3+4)
Final answer:
To use the distributive property to write an expression equivalent to 5×(3+4), distribute the 5 to both the 3 and the 4 and simplify.
Explanation:
To use the distributive property to write an expression equivalent to 5×(3+4), we need to distribute the 5 to both the 3 and the 4. This means we need to multiply 5 by each number inside the parentheses:
5 × 3 = 15
5 × 4 = 20
So, the expression equivalent to 5×(3+4) is 15 + 20, which simplifies to 35.
Which equation represents a linear function that has a slope of and a y-intercept of –6?
