Answer:
32/9
Step-by-step explanation:
2*(2)(8/9) = 4*8/9 = 32/9
Step-by-step explanation:
You are finding the whole
0.7 × 20 = 14
or
70% of 20 = 7/10 x 20 = 7/10 x 20/1 = 140/10
140/10
140/10 = 14/1
The minimum number of questions he need to do are 14
I'm not sure if you are finding the part or the whole
let me know if im wrong
Answer:
x-intercept of the graph of the function is,
Step-by-step explanation:
Given the function: ......[1]
x-intercept defined as the graph crosses the x-axis.
Substitute value of y = 0 in [1] and solve for x;
or
Take the inverse cotangent of both sides of the equation and solve for x;
3x = arccot (0)
We know the exact value of
then;
Divide both sides by 3 we get;
Since, the cotangent function is positive in the first and third quadrants.
The period of the function is so values will repeat every radians in both directions.
we have;
Therefore, the x-intercept of the graph of the function is ;
for every integer n;
A ratio is like a fraction, so since you are provided with the numbers its easy to put it into a ratio
depth is 3.8km
width is 7600km
ratio is 3.8:7600
