Answers
Answer:
C. 2.50x+10
Step-by-step explanation:
if x represents the miles driven and it is 2.50 per mile driven then 2.50x is the first part of the equation. If there is a fee of 10 then that adds to the miles driven

Answer:
y = 9/2x - 7y = 2/3xStep-by-step explanation:
Slope intercept form
y = mx + b1. Slope = 9/2, point (2,2)
2 = 9/2*2 + b ⇒ b = 2 - 9 ⇒ b = -7y = 9/2x - 72. Slope = 2/3, point (3,2)
2 = 2/3*3 + b ⇒ b = 2 - 2 = 0y = 2/3xAnswer:
y = 9/2x - 7
y = 2/3x
Step-by-step explanation:
Question 1:
y = mx + b
y = 9/2x + b
2 = 9/2(2) + b
2 = 9 + b
-7 = b
y = 9/2x - 7
Question 2:
y = mx + b
y = 2/3x b
2 = 2/3(3) + b
2 = 2 + b
0 = b
y = 2/3x

In a sale, normal prices are reduced by 20%.
Andrew bought a saddle for his horse in the sale.
The sale price of the saddle was £220.
Calculate the normal price of the saddle.
Answers
Answer:
the normal rice of saddle is £275
Step-by-step explanation:
normal prices are reduced by 20% to get sale price
this can be shown that
normal price = 100%
and sale price is 80% of normal price (100%-20%)
therefore we can use cross multiplication
% amount( £)
80 : 220
100 : x
80x = 22000
x = 22000/80
x = 275
the normal rice of saddle is £275

After two consecutive years of 6% losses, what rate of return in the third year will produce a cumulative gain of 7%? Note: Please make sure your final answer(s) are in percentage form and are accurate to 2 decimal places. For example 34.56%. Rate of return = 0.00 %
Answers
The rate of return of approximately 17.95% in the third year would produce a cumulative gain of 7% after two consecutive years of 6% losses.
To solve the problem completely, let's calculate the rate of return required in the third year to achieve a cumulative gain of 7% after two consecutive years of 6% losses.
1. Calculate the total loss over the two years:
Total loss = (1 - 0.06) * (1 - 0.06) = 0.9416
2. Calculate the target cumulative gain:
Cumulative gain = 1 + 0.07 = 1.07
3. Set up the equation to solve for the rate of return:
1 + Rate of return = Cumulative gain / (1 - Total loss)
4. Substitute the values into the equation:
1 + Rate of return = 1.07 / (1 - 0.9416)
1 + Rate of return = 1.07 / 0.0584
5. Solve for the rate of return:
Rate of return = (1.07 / 0.0584) - 1
Rate of return ≈ 17.95%
Therefore, a rate of return of approximately 17.95% in the third year would be needed to achieve a cumulative gain of 7% after two consecutive years of 6% losses.

Suppose that 12% of test scores for the unit 1 test were above 85 and 8% were below 70. Assuming a normal
distribution, what is the mean and standard deviation of the distribution of test scores?
Answers
Answer:
Mean = 78.2
Standard deviation = 5.8
Step-by-step explanation:
Mathematically z-score;
= (x-mean)/SD
From the question;
12% of test scores were above 85
Thus;
P( x > 85) = 12%
P(x > 85) = 0.12
Now let’s get the z-score that has a probability of 0.12
This can be obtained from the standard normal distribution table and it is = 1.175
Thus;
1.175 = (85 - mean)/SD
let’s call the mean a and the SD b
1.175 = (85-a)/b
1.175b = 85 - a
a = 85 - 1.175b ••••••••(i)
Secondly 8% of scores were below 70
Let’s find the z-score corresponding to this proportion;
We use the standard normal distribution table as usual;
P( x < 70) = 0.08
z-score = -1.405
Thus;
-1.405 =( 70-a)/b
-1.405b = 70-a
a = 70 + 1.405b ••••••(ii)
Equate the two a
70 + 1.405b = 85 - 1.175b
85 -70 = 1.405b + 1.175b
15 = 2.58b
b = 15/2.58
b = 5.81
a = 70 + 1.405b
a = 70 + 1.405(5.81)
a = 78.16
So mean = 78.2 and Standard deviation is 5.8

For the hyperbola z² - y² = 3, the following statements are true: The intercepts of the hyperbola are (±√√3, 0). The foci (focus points) of the hyperbola are (±√6,0). The oblique asymptotes are y = ±x.
The given hyperbola equation z² - y² = 3 can be analyzed to determine its properties.
1. The intercepts of the hyperbola are the points where it intersects the coordinate axes. For this hyperbola, the x-intercepts are (±√√3, 0), where z = 0 and y = 0.
2. The foci (focus points) of a hyperbola are the fixed points inside the curve that determine its shape. For this hyperbola, the foci are located at (±√6,0).
3. Oblique asymptotes are lines that the hyperbola approaches as the distance from the origin increases. For this hyperbola, the oblique asymptotes are y = ±x.
Therefore, among the given options, the statements that are true for the hyperbola z² - y² = 3 are: The intercepts of the hyperbola are (±√√3, 0), the foci (focus points) are (±√6,0), and the oblique asymptotes are y = ±x.

Complete the equation for the standard form of the line that has an x-intercept of –4 and a y-intercept of 3. I asked this before but I still didn't get the answer that I wanted. :(
Answers
Answer: 3x - 4y = -12
Step-by-step explanation:
Intercept form is x/a + y/b = 1, where a is the x-intercept and b is the y-intercept. From the question we have:
x-intercept = -4 (a = -4)
y-intercept = 3 (b = 3)
So we can plug this into the intercept form equation:
x/a + y/b = 1
x/-4 + y/3 = 1
(The LCM of -4 and 3 is -4x3 = -12, so we can multiply both sides of the equation by -12 to get rid of the denominators)
-12x/-4 + -12y/3 = -12 (Cancelling)
3x + (-4y) = -12
3x - 4y = -12
In their last game, the New England Patriots scored 9 points in the first half. In the second half, they scored three less than two times the points in the first half. What is the ratio of the points scored in the second half to the total number of points scored? Give your ratio using a colon.
Answers
Answer:
In the first half, they scored 9 points.
in the second half, they scored:
-3 + 2*9 = 18 - 3 = 15 points.
The total number of points scored is 9 + 15 = 24 points.
Now we want to know:
"What is the ratio of the points scored in the second half to the total number of points scored?"
The ratio between two numbers a and b is written as:
a:b
In this case, the ratio will be:
15:24
But we should simplify this ratio, we can divide both sides by the same number and the ratio will remain unchanged.
As both numbers are multiples of 3, we can divide both sides by 3.
15/3 = 5.
24/3 = 8
Then:
15:24 = 5:8
The ratio is 5:8

Trevor is a car salesman.
He bought a car for £5000
Currently he is holding a sale with 35% off the price of all cars.
Trevor wants to sell the car so that he makes a 10% pro\it on the price he paid.
How much should Trevor advertise the car for?
Answers
Answer:
£3575
Step-by-step explanation:
If Trevor bought the car for £5000, he wants to make a 10% profit on it.
His profit will be 10% of £5000 which is (10/100) x 5000 = £500.
So, his total cost for the car and profit will be £5000 + £500 = £5500.
Since Trevor is holding a sale, he is offering a 35% discount on the car. Therefore, the discounted price of the car will be:
Discount = 35/100 x £5500 = £1925
The price at which Trevor should advertise the car is the original price minus the discount:
Advertised price = £5500 - £1925 = £3575
Therefore, Trevor should advertise the car for £3575.
. marcos has 78 toy cars. he arranges the toy cars into 6 equal groups. how many toy cars are in each group? complete the diagram started below to show your work.
Answers
Marcos has a total of 78 toy cars, and he wants to arrange them into 6 equal groups.
To determine the number of toy cars in each group, we divide the total number of toy cars by the number of groups: 78 ÷ 6 = 13. Therefore, there will be 13 toy cars in each group.
This can be represented as 78 divided by 6 equals 13. By dividing the total number of toy cars by the number of groups, Marcos ensures that each group has an equal distribution of toys.
This allows for a fair and balanced arrangement of the toy cars, making it easier for Marcos to organize and manage them.
