Answer:
that would be 1305.5
Step-by-step explanation:
D. Because the 3 is the rate and the 6 is what was already there.
Answer:
Step-by-step explanation:
∠ABD = 100
∠ABC + ∠CBD = ∠ABD
4x + 2 + 3x - 7 = 100
4x + 3x +<u>2 -7 </u>= 100 {Combine like terms}
7x <u> -5 </u> = 100
Add 5 to both sides
7x = 100 +5
7x = 105
Divide both sides by 7
x = 105/7
x = 15
∠CBD = 3x - 7
= 3*15 - 7
= 45 - 7
∠CBD = 48
At that rate, cyclists will cover a distance of 57 meters in 3 seconds.
The ratio of two related quantities expressed in several units is known as a rate.
Speed is the ratio of the distance traveled in a period of time. Speed is given by:
Speed = distance/time
The cyclist's speed, given that he completes 380 meters in 20 seconds, will be:
Speed = distance/time
s = d/t
v = 380 m / 20 s
v = 19 m/s
If he travels at this rate, at 3 seconds, the distance is:
Speed = distance/time
Distance = Speed × time
d = s × t
d = 19 m/s × 3 s
d = 57 m
Therefore,
At that rate, the cyclist will travel a total distance of 57 meters in 3 seconds.

For this case we have the following polynomial:
Rewriting the polynomial we have:
From here, we can solve the polynomial using the quadratic equation
We have then:
Therefore, the solutions are:
