Step-by-step explanation:
When Rachel puts gas in her car, she records the distance that she has driven since her last
fill-up and the number of gallons of gas that her car has used. She uses this information to
predict the amount of gas that her car will use to travel different distances,
g=0.04 times d
Step-by-step explanation:
if you multiply 0.04 with every number under the d column then you’ll get the outcome of each number under g
The relationship between the number of gallons of gas that the car uses g, and the number of miles the car has driven d, is given by the equation g=0.04d. Since the values of g and d are linearly connected.
Which is said to be a Linear equation?A linear equation is an algebraic equation that has the highest degree as 1.The general form of the linear equation is [tex]y=ax+c[/tex]. Where y is the dependent variable and x is the independent variable.So, as the value of x increases the value of y also increases linearly and forms a straight line.Given data:It is given that,
A table of content about the distance traveled by Rachel and the gas used for that distance.
The distance is given in miles as d and the gas is given in gallons as g
The values of d given in the table are 14, 70, 109, and 140. Here the order is increasing.
The values of g given in the table are 0.56, 2.8, 4.36, and 17.6. Here also the order is increasing.
Finding the relationship between g and d:Since the values of g and d are increasing linearly and g is depending on d, consider a linear equation as follows:
[tex]g=ad+c[/tex]
Finding a and c from the obtained equation:
From the table, when d=14, g=0.56 and d=70, g=2.8
On substituting these values in the equation we get
0.56=14a+c
2.8=70a+c
Subtracting 1st equation from the 2nd equation,
2.8-0.56=(70a+c)-(14a+c)
⇒ 2.24=56a
⇒ a=0.04
On substituting a value in any of the equations we get
0.56=(0.04)(14)+c
⇒ c=0
Thus, the required equation becomes g=0.04d. This says that the g and d values are linearly related to each other.

Suppose that the amount of algae in a pond doubles every 3 hours. If the pond initially contains 50 pounds of algae, how much algae will be in the pond after 8 hours.In this exponential situation, what would the y-intercept be? CHOICES:
(0,3)
(0,2)
(0,50)
(0,8)
Answer:
After 8 hour there will be 317.64 pounds of algae.
y-intercept: (0, 50)
Step-by-step explanation:
At time = 0 hours, there are 50 pounds of algae, after 3 hour there will be 100 pounds of algae, after 6 hour there will be 200 pounds of algae, and so on.
Exponential growth is modeled by the following equation:
y = x0*(1 + r)^t
where x0 is the amount of algae at the beginning, r is the rate of change, and y is the amount of algae after t hours. Replacing with data:
100 = 50*(1 + r)^3
2 = (1 + r)^3
ln(2) = 3*ln(1 + r)
r = exp(ln(2)/3) - 1
r = 0.26
This result can be checked as follows
y = 50*(1 + 0.26)^6 = 200
After 8 hours:
y = 50*(1 + 0.26)^8 = 317.64
The y-intercept corresponds to t = 0
y = 50*(1 + 0.26)^0 = 50
kenneth drove 177.55 miles in 3 7/20 hours. what was his average speed
Kenneth's average speed, we divide the total distance by the total time traveled. In this case, Keneth's average speed was approximately 52.91 miles per hour.
Kenneth's average speed, you can use the formula:
Average Speed = Total Distance/Total Time.
In this case, Kenneth drove 177.55 miles in 3 7/20 hours.
First, convert the mixed number time to an improper fraction:
3 7/20 = 67/20.
Now, substitute the values into the formula:
Average Speed = 177.55 / (67/20).
To divide by a fraction, multiply by its reciprocal:
Average Speed = 177.55 * (20/67).
Average Speed ≈ 52.91 miles per hour.
Therefore, Keneth's average speed was approximately 52.91 miles per hour.

Mandy paints four square walls that are ten feet on each side. Which expression represents the total square footage that Mandy painted?
4 × 10 squared
4 squared × 10
4 × 10 × 2
10 squared + 4
Answer:
i think its c
Step-by-step explanation:
Final answer:
The correct expression for the total square footage that Mandy painted is 4 × 10 squared, which totals 400 square feet when calculated.
Explanation:
The expression that represents the total square footage that Mandy painted when she paints four square walls that are ten feet on each side is 4 × 10 squared. To understand why, let us analyze a related problem where Marta has one square with a side length of 4 inches and another larger square with dimensions that are twice the first square, which means the side length of the larger square is 8 inches (4 inches × 2).
The area of a square is calculated by squaring its side length, so the smaller square has an area of 16 square inches (4 inches squared), and the larger square will have an area of 64 square inches (8 inches squared). This demonstrates that the area of the larger square is four times larger than the area of the smaller square, as the scale factor of the side lengths is squared to obtain the ratio of the areas.
Similarly, for Mandy's wall painting, each wall is 10 feet by 10 feet, so the area of one wall is 10 feet squared, which equals 100 square feet. Since there are four walls, the total area is 4 × 100 square feet, or 400 square feet in total. The correct expression for the total square footage Mandy painted is 4 × 10 squared.

True or false: the Pythagorean theorem can be applied to every triangle
The Pythagorean theorem can only be applied to right triangles.
Explanation:The Pythagorean theorem can be applied to right triangles only.
It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
So, while the Pythagorean theorem cannot be applied to every triangle, it can be used to find the length of one side of a right triangle given the lengths of the other two sides.

the perimeter of an equilateral triangle is 150cm. If the length of the altitude of the triangle is x√3cm, what is the value of x?
Answer:
X = 25
Step-by-step explanation:
To solve this question, we'll first of all find determine the side length of the triangle from the perimeter.
Perimeter of an equilaterial triangle = 3 * s
S = side length
Perimeter = 150cm
150 = 3s
S = 150 / 3
S = 50cm
The side lengths are 50cm each since they are all equal.
To find x,
We have to divide the triangle equally into two different part.
Check the first attachment for better illustration on how the equilaterial triangle is.
Check the second attachment for better illustration on the triangle when its divided into a right angle triangle.
From the right angle triangle, we can use pythagorean theorem to solve for x
a² = b² + c²
a = 50cm
b = 25cm
c = x√(3)
50² = [x√(3)]² + 25²
2500 = x² * 3 + 625
2500 - 625 = 3x²
1875 = 3x²
X² = 1875 / 3
X² = 625
X = √(625)
X = 25

An amusement park's cost for cotton candy is $1.50. The markup rate for cotton candy is
300%. What is the price of cotton candy at the park?
Answer:
The answer is $6
Hope this helps!
The price of cotton candy at the park is $6.00.
The markup rate of 300% means the price is increased by three times the cost. So, $1.50 * 3 = $4.50 is the markup cost. Adding the original cost to the markup cost gives $1.50 + $4.50 = $6.00.

Sanjay has 59 toy cars. 12 of the cars are blue and 23 of the cars are red. The rest of the cars are white.
How many more toy cars are white than blue? Enter the answer in the box.
toy cars
Answer: 12
Step-by-step explanation: 12+23 = 35
59-23 is 24
24 is the number of white cars so if 12 of the cars are blue, you just subtract 12 from 24 giving you 12 as the difference between white and blue cars
Final answer:
Sanjay has 12 more white toy cars than blue. There are 24 white cars in total after subtracting the number of blue and red cars from the total.
Explanation:
Sanjay has a total of 59 toy cars, of which 12 are blue and 23 are red. To find out how many toy cars are white, we need to subtract the number of blue and red cars from the total number of cars.
Total number of cars = 59
Number of blue cars = 12
Number of red cars = 23
Subtract the number of blue and red cars from the total:
59 - 12 - 23 = 59 - 35 = 24
So, there are 24 white cars.
To find out how many more white cars there are than blue cars, subtract the number of blue cars from the number of white cars:
24 (white cars) - 12 (blue cars) = 12
Therefore, there are 12 more white toy cars than blue toy cars.

171 = a(1-8/27)/(1/3)
171 = a(19/27)/(1/3)
171 = a × 19/27 × 3/1
171 = a × 19/9

Study the following diagram, where points C and D lie on circle A.
Point B lies in the exterior of circle A.

The diagram as described in the problem, where segment B C equals negative 2 x plus 85 and segment B D equals 5 x minus 48.
What is the length of BC¯¯¯¯¯¯¯¯?
Enter the correct value.
Answer:
Triangle ACB = Triangle ADB
=> BC = BD
=> -2x+85 = 5x - 48
=> x = 133/7 = 19
=> BC = -2 x 19 + 85 = 47
If we are provided with the value of AC or CD, we can calculate the length of BC is 47
Let's first determine the lengths of segment BC and BD in terms of x using the given expressions:
BC (B C¯¯¯¯¯¯¯¯) = -2x + 85
BD (B D¯¯¯¯¯¯¯¯) = 5x - 48
Now, as ACB and ADB are right angles, we can utilize the property of perpendicular chords intersecting a circle to find the value of x. When two chords intersect inside a circle, the product of their segments is equal. Therefore, we can set up the following equation:
BC * BD = (AC * CD) [Property of perpendicular chords intersecting]
Substitute the values:
=> BC = BD
When we simplify this one, then we get,
-2x+85 = 5x - 48
Then the value of x is calculated as,
x = 133/7 = 19
BC = -2 (19) + 85 = 47
