Answer:
A 5% raise can be written as 1.05 so the new salary is 25100 * 1.05 = $26355.
Answer:
1) 15 feet per second
2) distance after 3 seconds 45 feet
3) slower
Step-by-step explanation:
1) 30/2 = 15
2) 15 x 3
3) 55/4 = 13.75 < 15
The scooter travels 15 feet after 1 second, 45 feet after 3 seconds, 60 feet after 4 seconds, and 75 feet after 5 seconds. The speed of the scooter is 15 feet per second. The skateboard is going slower than the scooter.
To complete the double number line, we need to determine the distance the scooter travels after 1, 3, 4, and 5 seconds. Since the scooter travels 30 feet in 2 seconds at a constant speed, we can determine the distance for each time by finding the proportion:
After 1 second: 30 feet / 2 seconds = 15 feet
After 3 seconds: 30 feet / 2 seconds * 3 seconds = 45 feet
After 4 seconds: 30 feet / 2 seconds * 4 seconds = 60 feet
After 5 seconds: 30 feet / 2 seconds * 5 seconds = 75 feet
The speed of the scooter is the same as its constant speed, which is 30 feet / 2 seconds = 15 feet per second.
The distance the scooter travels after 3 seconds is 45 feet.
Since the scooter traveled 30 feet in 2 seconds, and the skateboard traveled 55 feet in 4 seconds, we can compare their speeds. The scooter traveled 30 feet in 2 seconds, which means its speed is 30 feet / 2 seconds = 15 feet per second. The skateboard traveled 55 feet in 4 seconds, so its speed is 55 feet / 4 seconds = 13.75 feet per second. Therefore, the skateboard is going slower than the scooter.

convenience samples survey each participant once, and voluntary samples survey each participant numerous times.
convenience sampling is a method of random sampling, and a voluntary sample is not.
convenience sampling is not a probability-based method, and voluntary sampling is.
Answer: A convenience sample is structured based on accessibility to the researcher, and a voluntary sample is based on participant interest.
Step-by-step explanation:
For the conventional sample the researcher chooses a sample that is readily available in some non-random way. Thus, it is structured based on accessibility to the researcher.
But for the voluntary sample the researcher puts out a request for participants of a population to join the sample, and participants decide whether or not to be in the sample. Thus, it is based on participant interest.
On creating and solving the linear inequality based on the given conditions, the charity needs at least 1000 race entries to raise at least $55,000.
Linear inequalities are the expressions where any two values are compared by the inequality symbols such as, '<', '>', '≤' or '≥'. These values could be numerical or algebraic or a combination of both.
Let the number of race entries be x.
5000 + 55x + 10000 - 15x >= 55000
40x >= 40000
x >= 1000
The charity needs at least 1000 race entries to raise at least $55,000.

The area and perimeter of an isosceles trapezoid with a 60° base angles and bases 9 and 13 is 38.105 squared units and 24 units respectively.
The area of the isosceles trapezoid is the space occupied by it. It can be find out using the following formula,
Permiter of the isosceles trapezoid is the total length of the boundary by which it is enclosed. It can given as,
Here (a,b) are the base side (c) is the side of leg and (h) is the height.
The image of the given isosceles trapezoid is attached below. Let the value of leg is x units. Thus using right angle property the cos theta is,
And the height of this trapezoid is,
Thus the area of the solid is,
The perimeter of the solid is,

Be sure to include the correct unit in your answer.
The volume of the cylindrical tank with a radius of 5.5ft and a height of 12ft can be calculated using the formula V=πR²h. When we plug in the values, we get a volume of 1139.82ft³ which rounds up to 1140ft³.
The volume of a cylindrical tank is calculated by the formula V = πR²h, where R is the radius and h is the height. In this case, the radius of the tank is 5.5ft and the height is 12ft. Let's plug these values into our formula.
Volume = π × (5.5ft)² × 12ft = 3.14 × 30.25ft² × 12ft = 1139.82ft³
When we round this to the nearest whole number, we get a volume of 1140 cubic feet for the tank.
