Yesterday, Rachel went on a bike ride. Her average speed was 9 miles per hour. Today, she went on another ride, this time averaging 14 mlles per hour. In the two days, she biked for a combined total time of 12 hours. Let x be the number of hours she biked yesterday. Write an expression for the combined total number of miles she biked in the two days.
Rachel rode her bike a total distance in miles over the course of two days, as shown by the expression: -5x + 168.
What is meant by term speed of object?Velocity is the pace and directions of an object's movement, whereas speed is really the time rate which an object is travelling along a path. In other words, velocity is a vector, whereas speed is just a scalar value.Let x be the duration of Rachel's bicycle ride yesterday.
Distance = speed * time
According to information provided, Rachel's average speed yesterday was 9 miles per hour.Therefore, the distance travelled in x hours would be: 9x.Additionally, we are informed that Rachel biked nine times in total 12 hours.Therefore, the second day's biking time would be: 12 - x.At a pace of 14 miles per hour, the distance travelled would be: 14(12 - x)The total distance that Rachel would travel is: 9x + 14(12 - x)Thus, the equation becomes.
= 9x + 14(12 - x)
On solving;
= 9x + 168 - 14x
=-5x + 168
Rachel rode her bike a total of miles over the course of two days, as shown by the expression: -5x + 168.

What is ellipse?
An ellipse in mathematics is a plane curve that has two focal points and is such that the sum of the two distances from any point on the curve to the focal points is a constant. It generalizes a circle, a special kind of ellipse in which the two focal points coincide.
Given:
The equation of ellipse is,
[tex]\frac{(x-2)^2}{81}+(\frac{(y+8)^2}{100}=1[/tex]
Since, the general form of ellipse is,
[tex]\frac{(x-h)^2}{a^2}+\frac{(y-k)^2}{b^2}=1[/tex]
where,
(h, k) is the center of ellipse
a is the minor axis
b is the major axis.
Here (h, k) = (2, -8) is the center of the ellipse.
9 is the minor axis and 10 is the major axis of the ellipse.
Also the graph of ellipse connects (2, 2), (11, -8), (2, -18) and (-7, -8) with smooth curve.
Hence, the center of the ellipse is (2, -8).
The endpoints of the major axis are 10 units from the center.
The endpoints of the minor axis are 9 units from the center.
To graph the ellipse, connects (2, 2), (11, -8), (2, -18) and (-7, -8) with smooth curve.

What is proportion?A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 4(for every one boy there are 3 girls) 1 / 4 are boys and 4 / 5 are girls. 0.20 are boys (by dividing 1 by 5). It can also be defined as the size, number, or amount of one thing or group as compared to the size, number, or amount of another.
The cost of 2.5kg of potatoes is £1.40
Therefore the cost of 1kg potatoe = 1.40/2.5 = £0.56
This means that the cost of 4.25 kg = 0.56× 4.25
= £2.38

What two rational expressions sum to 3x−2x2−x−12 ?
Enter your answer by filling in the boxes. Enter your answer so that each rational expression is in simplified form.
Answer and Explanation: To get the two terms on the right to combine into one term, we need the denominators of both terms to be the same. To do this we can plug in x+3 for the bottom left denominator and x-4 for the bottom right denominator. This makes both denominators (x+3)(x-4).
The numerators of both terms on the right just have to add up to 3x-2. One way we could do this is to the right one as 3x and the other as -2 or vice versa.
(x+3)(x-4) simplifies to x^2-x-12 which is why the denominator of the term on the left is that.

A person rides a Ferris wheel that turns with constant angular velocity. Her weight is 520.0 N. At the top of the ride her apparent weight is 1.5N different from her true weight. (a) Is her apparent weight at the top 521.5N or 518.5N Why? (b) What is her apparent weight at the bottom of the ride? (c) If the angular speed of the Ferris wheel is what is its radius?
(a) At the top of the ride, her apparent weight is 518.5 N. This is because, at the top of the ride, the centripetal force acting on her is directed towards the center of the Ferris wheel, which acts in opposition to her weight. Since her weight is 520 N, and the centripetal force is 1.5 N, the net force acting on her is 518.5 N.
Apparent weight, also known as effective weight or net weight, is the weight that an object appears to have when it is in motion. It is the force that an object feels as a result of a combination of its true weight and any additional forces acting on it, such as the centripetal force.
(b) At the bottom of the ride, her apparent weight is 520.5 N. This is because, at the bottom of the ride, the centripetal force acting on her is in the same direction as her weight, so the net force acting on her is the sum of her weight and the centripetal force.
(c) The radius of the Ferris wheel can be determined using the formula v^2 = r * g, where v is the angular velocity, r is the radius and g is the acceleration due to gravity. Given that angular speed and the apparent weight is known, you can use this formula to find the radius.

Gabriel models the volume of a popcorn box as a right rectangular prism. Its dimensions are 2 1/2 in by 2 3/4 in by 5 in. If the box contains 26 cubic inches of popcorn, what percent is full? Round your answer to the nearest whole number if necessary. please really asap brainliest
To find the percent full of the popcorn box, we need to divide the volume of popcorn in the box by the total volume of the box, and then multiply by 100 to convert the result to a percentage.
First we need to find the total volume of the box:
V = l x w x h
V = (2 1/2 in x 2 3/4 in x 5 in) = (5/2 in x 7/4 in x 5 in) = (35/4 in^3) = 8.75 in^3
Now we can calculate the percent full:
percent = (26 in^3 / 8.75 in^3) x 100 = 2.97 x 100 = 297%
The popcorn box is 297% full.
It's worth noting that 297% means that the popcorn box is almost 3 times full

Therefore , the solution of the given problem of ratio comes out to be 300,000.
A ratio is defined.A portion or fraction in mathematics displays how frequently one number is included in another. For instance, if there are eight orange and six lemons in a fruit plate, the proportion of oranges to lemonade is eight to six, or 8:6, which is comparable to the ratios 4:3 or the decimal 1.333.
Here,
We must use our grasp of proportionality to establish the maximum amount of shares that can be owned in this exercise.
The 20 huge variations will allow Blackbird Oil to store a total of 300,000 gallons.
