How many gallons of fuel does Roselyn need for her journey? Choose 1 answer: Choose 1 answer: A 2.52, point, 5 gallons B 3.1.25, point, 125 gallons C 0.20, point, 2 gallons D 5 gallons
The number of gallons of fuel Roselyn need for her journey is:
D. 5 gallons
Step-by-step explanation:It is given that:
Roselyn wants to drive her car at a speed of 60 miles per hour for 1.25 hours.
This means that the total distance she covers in 1.25 hours is:
[tex]60\times 1.25=75\ \text{miles}[/tex]
( Since, we know that speed is defined as the ratio of distance to time.
i.e.
[tex]Speed=\dfrac{Distance}{Time}\\\\i.e.\\\\Distance=Speed\times Time[/tex] )
Also, Her car has a fuel efficiency of 15 miles per gallon.
i.e.
She could cover 15 miles with 1 gallon of fuel.
Hence, in order to cover 75 miles.
i.e. to cover (15×5) miles she needs (1×5) gallons of fuel
i.e. she needs 5 gallons of fuel to cover 75 miles.
Write the equation of the parabola in vertex form.
vertex (0,4), point (1,-3)
f(x)=
The equation of the parabola in vertex form is f(x) = -7x^2 + 4
Explanation:To write the equation of a parabola in vertex form, we use the formula f(x) = a(x - h)^2 + k where (h, k) represents the vertex. In this case, the vertex is (0,4) so our equation becomes f(x) = a(x - 0)^2 + 4 which simplifies to f(x) = ax^2 + 4. To find the value of a, we substitute the coordinates of the point (1,-3) into the equation and solve for a. Plugging in these values, we get -3 = a(1)^2 + 4, which simplifies to -3 = a + 4. Solving for a, we find that a = -7. Therefore, the equation of the parabola in vertex form is f(x) = -7x^2 + 4.

One side of a triangle is increasing at a rate of 9 cm/s and a second side is decreasing at a rate of 2 cm/s. if the area of the triangle remains constant, at what rate does the angle between the sides change when the first side is 21 cm long, the second side is 36 cm, and the angle is π/6? (round your answer to three decimal places.)
The rate at which the angle between the sides of the triangle is changing is 4/9 radians per second.
Explanation:In this problem, we are given that one side of the triangle is increasing at a rate of 9 cm/s and a second side is decreasing at a rate of 2 cm/s. We need to find the rate at which the angle between the sides is changing.
To solve this, we can use the formula:
angle_rate = (-side2_rate/side1)*(cos(angle))/(sin(angle))
Substituting the given values:
angle_rate = (-(-2)/9)*(cos(π/6))/(sin(π/6))
Simplifying, we get:
angle_rate = 4/9
Therefore, the rate at which the angle between the sides is changing is 4/9 radians per second.

Emily dropped a coin from rest, and the distance traveled by the coin is given by the formula below, where s is the distance the coin has fallen, g is a constant representing Earth's gravity, and t is the duration of time over which the coin falls. Emily measured the distance in feet, the time in seconds, and now wants to calculate the value of g. What must be the units of g?
To match the units of distance in feet and time in seconds, the units of the gravitational constant g must be feet per second squared (ft/s^2). On Earth, g is roughly 32.17 ft/s² in U.S. Customary units.
When Emily drops a coin from rest, the distance traveled by the coin (s) can be used to calculate the acceleration due to gravity (g) when the time (t) the coin took to fall is known. The formula provided suggests that distance is equal to 0.5 times gravity acceleration times the square of time (s = 0.5 * g * t²).
Given that Emily measured the distance in feet and the time in seconds, the units for g must be compatible with these measurements. Since distance is in feet and time is squared in seconds, the unit for g must be feet per second squared (ft/s²) to ensure that all units cancel out correctly, leaving us with the unit of distance in feet. On Earth's surface, the value of g using U.S. Customary units is approximately 32.17 ft/s².

The distance from town A to town B is divided into 8 equal parts. So far, a bus has traveled 12 Miles. How far apart are town A and town B? Explain
Town A and Town B are 1.5 miles apart.
Explanation:The distance between town A and town B can be found by multiplying the distance traveled by the number of equal parts that make up the whole distance. In this case, the bus has traveled 12 miles out of 8 equal parts. To find the total distance, we can set up a proportion:
12 miles / 8 parts = x miles / 1 part
Cross-multiplying gives us:
8x = 12 miles
Dividing both sides by 8 gives us:
x = 1.5 miles
Therefore, town A and town B are 1.5 miles apart.
does 6% of a pound weigh more than an ounce
Answer:
6% of a pound does not weigh more than 1 ounce.
Step-by-step explanation:
First, we will calculate 6% (0.06) of 1 pound.
0.06 × 1 lb = 0.06 lb
1 pound is equal to 16 ounces. 0.06 pounds, expressed in ounces is:
0.06 lb × (16 oz/ 1 lb) = 0.96 oz
6% of a pound = 0.96 oz
0.96 oz < 1 oz
Due to the transitive property, we can affirm that 6% of a pound does not weigh more than 1 ounce.
