Answer:
The distance at which the timekeeper is the race car at the start is 50 feet.
Step-by-step explanation:
You know that the car's distance from the timekeeper is represented by
y=293*x +50
where x is time in seconds and y is distance in feet from the timekeeper's position.
You want to determine how far the timekeeper is from the race car at the start. That is, the distance the timekeeper is from the car when the time is equal to zero. This indicates that x = 0. Replacing x by that value in the expression of the distance of the car from the timekeeper as a function of time and solving:
y=293*0 +50
you get:
y=50
<u><em>The distance at which the timekeeper is the race car at the start is 50 feet.</em></u>
Given that the cost of b burgers and h hot dogs is given by 3.25b + 2h.
Therefore, the cost of 4 burgers and 6 hot dogs is given by 3.25(4) + 2(6) = 13 + 12 = $25.
The equation for r: d = rt would be 'r equals d over t.'
How, you might ask? Well, let's consider this example:
You might already know what d = rt stands for... "Distance equals rate times time", so if you divide the two sides by 't', you would come up with r = d/t. So that would finalize as your answer for this question.
Answer:
Option (3) is the answer.
Step-by-step explanation:
Given question is incomplete; find the complete question in the attachment.
Jewelry made by Nala is a composite figure having three fourth of a circle and two sides of a square.
Perimeter of the whole figure will give us the length of wire needed to design the jewelry.
Perimeter of three fourth of a circle P(circle) = 
Here, r = radius
P(circle) = 
= 14.14 cm
Perimeter of the complete (composite) figure = 14.14 + 3 + 3
= 20.13
≈ 20.1 cm
Therefore, Option (3) is the answer.
