Therefore, it will take Jessica 20 minutes to bike to Gar-Field High at 10 miles per hour.
What is speed?Speed is the measure of how quickly an object, or a person is moving in a certain direction. It is defined as the distance traveled per unit of time, typically expressed in meters per second (m/s) or kilometers per hour (km/h).
For example, if a car travels a distance of 100 kilometers in 2 hours, its speed would be 50 km/hour (100 km ÷ 2 hours = 50 km/h). Similarly, if a person runs 100 meters in 10 seconds, their speed would be 10 meters per second (100 meters ÷ 10 seconds = 10 m/s).
Speed is a scalar quantity, meaning it has only magnitude and no direction. However, velocity is a related concept that includes both speed and direction.
) The direct variation equation for the relationship between the number of cups of flour and the number of cookies can be written as:
\(number of cookies = k x cups of flour\)
where k is the constant of variation.
To find k, we can use the given information: 68 cookies require 4 cups of flour.
So,\(k = 68/4 = 17.\)
Therefore, the direct variation equation is:
\(number of cookies = 17 x cups of flour\)
b) To find how many cups of flour are needed to make 85 cookies, we can use the direct variation equation we just found:
\(number of cookies = 17 x cups of flour\)
Plugging in the given value of number of cookies:
\(85 = 17 x cups of flour\)
Solving for cups of flour, we get:
\(cups of flour = 85/17 = 5\)
Therefore, 5 cups of flour would be needed to make 85 cookies.
c) The inverse variation equation for the relationship between time and speed can be written as:
\(time = k/speed\)
where k is the constant of variation.
To find k, we can use the given information: it takes Jessica 50 minutes to bike to Gar-Field High at 4 miles per hour.
\(So, k = 50 x 4 = 200.\)
Therefore, the inverse variation equation is:
\(time = 200/speed\)
To find how long it will take her if she rides at 10 miles per hour, we can plug in the given speed:
\(time = 200/10 = 20 minutes.\)

The work done by the force of friction is μmgd.
The work done by the applied force is equal to the displacement of the block (d) multiplied by the component of the force parallel to the displacement. If the applied force is F and the angle between the force and the displacement is θ, then the component of the force parallel to the displacement is Fcos(θ).
Therefore, the work done by the applied force is given by dFcos(θ). The force of friction will also do work, which is equal to the displacement of the block multiplied by the force of friction. The force of friction is given by μN, where N is the normal force and is equal to the weight of the block (mg). Therefore, the work done by the force of friction is μmgd, where d is the displacement.
Correct Question :

Pearl writes down seven consecutive integers, and adds them up. The sum of the integers is equal to $\frac{21}{4}$ times the largest of the seven integers. What is the smallest integer that Pearl wrote down?
Answers
The smallest integer that Pearl wrote down is -12.Let's assume the smallest integer that Pearl wrote down is represented by the variable "x."
According to the given information, the sum of the seven consecutive integers is equal to $\frac{21}{4}$ times the largest integer.
The sum of consecutive integers can be expressed as the sum of an arithmetic series. The sum of an arithmetic series can be calculated using the formula:
Sum = (n/2)(first term + last term)
In this case, the first term is x and the last term is x + 6 (since there are seven consecutive integers). Therefore, the sum of the integers can be written as:
Sum = (7/2)(x + (x + 6))
Simplifying the equation:
(7/2)(2x + 6) = (21/4)(x + 6)
Multiplying both sides by 4 to eliminate the fractions:
14x + 42 = 21x + 126
Subtracting 14x from both sides:
42 = 7x + 126
Subtracting 126 from both sides:
-84 = 7x
Dividing both sides by 7:
-12 = x.

The sugar sweet company will choose from two companies to transport as sugar to market. The first company charges 4500 to rent trucks plus an additional fee of 175.25 for each third of sugar per second copy charges 3995 to rent trucks plus an additional fee of 200.50for each total of sugar.
Answers
The two companies charge the same when the amount of sugar is 20 thirds per second and the cost when the two companies charge the same is $8,125.
What is amount?
Amount is a term used to describe the quantity or size of something. It can refer to a specific quantity of a substance, such as an amount of money or an amount of a particular material, or it can refer to a more abstract concept, such as an amount of time or effort.
To find the amount of sugar for which the two companies charge the same, we need to set the two costs equal to each other and solve for the amount of sugar.
Let x be the amount of sugar in third per second. Then, the cost C1 charged by the first company is:
C1 = 4500 + 175.25x
And the cost C2 charged by the second company is:
C2 = 3995 + 200.50x
To find the amount of sugar for which the two companies charge the same, we set C1 equal to C2:
4500 + 175.25x = 3995 + 200.50x
Solving for x, we get:
25.25x = 505
x = 20
Therefore, the two companies charge the same when the amount of sugar is 20 thirds per second.
To find the cost when the two companies charge the same, we can substitute x = 20 into either of the cost equations. Let's use C1:
C1 = 4500 + 175.25x
C1 = 4500 + 175.25(20)
C1 = 8125
Therefore, the cost when the two companies charge the same is $8,125.

Q: A baseball is hit into the air by the Blue Jays' batting coach.
It's height h, in meters, after t seconds is h = - 4.9t² + 27.44t + 0.584
(a) write the equation in vertex form by completing the square
b) How high off the ground was the ball when it was hit?
c) When does the ball reach it's maximum height? what is it's maximum height?
d) For how long is the ball in the air ? Round answer to 1 decimal place
Answers
The ball is in the air for approximately 2.8 + √7 seconds, which rounds to 5.2 seconds when rounded to one decimal place.To write the equation in vertex form, we need to complete the square.
The given equation is h = -4.9t² + 27.44t + 0.584. We can rewrite it as:
h = -4.9(t² - 5.6t) + 0.584
Now, we want to complete the square inside the parentheses. To do this, we need to add and subtract the square of half the coefficient of t. In this case, the coefficient is -5.6, so we have:
h = -4.9(t² - 5.6t + (5.6/2)² - (5.6/2)²) + 0.584
Simplifying, we get:
h = -4.9((t - 2.8)² - 2.8²) + 0.584
Expanding further:
h = -4.9(t - 2.8)² + 4.9(2.8)² + 0.584
Thus, the equation in vertex form is: h = -4.9(t - 2.8)² + 34.328
b) The ball's height when it was hit can be found by evaluating the equation at t = 0:
h = -4.9(0 - 2.8)² + 34.328
h = -4.9(-2.8)² + 4.328
h = -4.9(7.84) + 34.328
h ≈ 0.784 meters
To find the time at which the ball reaches its maximum height, we can use the fact that the maximum height occurs at the vertex of the parabolic equation. The vertex of a parabola in the form h = a(t - h₀)² + k is given by (h₀, k). Comparing this to our equation, we can see that the vertex occurs at t = 2.8 and h = 34.328. Therefore, the ball reaches its maximum height at 2.8 seconds, and the maximum height is 34.328 meters.
The total time the ball is in the air can be determined by finding the time it takes for the ball to reach the ground. When the ball hits the ground, its height is 0. To find this time, we can set the equation equal to 0 and solve for t:
0 = -4.9(t - 2.8)² + 34.328
4.9(t - 2.8)² = 34.328
(t - 2.8)² ≈ 7
t - 2.8 ≈ ±√7
t ≈ 2.8 ± √7
Since time cannot be negative in this context, we can ignore the negative value.

A total of 600 advertisements were sold for a certain magazine. If 20 percent of the first 200 sold were in color, 40 percent of the next 300 sold were in color, and 80 percent of the last 100 sold were in color, what percent of the 600 advertisements were in color?
Answers
Answer:
40%
Step-by-step explanation:
First, find how many of the first 200 were in color:
200(0.2)
= 40
Then, find how many of the next 300 were in color:
300(0.4)
= 120
Find how many of the last 100 were in color:
100(0.8)
= 80
Then, add these all together to find how many were in color:
40 + 120 + 80
= 240
Then, divide 240 by 600 to find the percent that were in color:
240/600
= 0.4
So, 40% of the 600 advertisements were in color
