"Yes" the point (25, 75) lie on the straight line y=3x
The equation f of straight line is y = mx + c
where m is slope of line and c is intercept
Given straight equation is
y = 3x.....(1)
If we compare this equation with straight line equation. we get,
m = 3 and 0 is intercept,
Given point are (25, 75).
put these given point in equation (1)
75 = 3 (25).
75 = 75.
Therefore, the given statement is true.

Answer: 1
Step-by-step explanation:
The formula for calculating the sum of a Geometric series if the common ratio is greater than 1 is given as :
=
Where is the sum of terms , a is the first term , r is the common ratio and n is the number of terms.
From the question:
= 3280
a = ?
r = 3
n = 8
Substituting this into the formula , we have
3280 =
3280 =
Multiply through by 2 , we have
6560 = a ( 6560)
divide through by 6560, we have
6560/6560 = a(6560)/6560
Therefore : a = 1
The first term of the series is thus 1
Answer:
1
Step-by-step explanation:
The number of miles that she drives in 6 minutes will be 5 miles.
Speed is defined as the length traveled by a particle or entity in an hour. It is a scale parameter. It is the ratio of length to duration.
We know that the speed formula
Speed = Distance/Time
Frieda drove 20 miles in 24 minutes. The speed is calculated as,
S = 20 / 24
S = 5/6 miles per minute
The number of miles that she drives in 6 minutes is calculated as,
D = 5/6 x 6
D = 5 miles
