Hello :
(sec²x - 1) / sec²x = (sec²x / sec²x) -1/sec²x
= 1 -1/sec²x
= 1- (1/secx)²
= 1 -cos²x
= sin²x
Answer:
First, you need to find the number 2/5 on the number line.
Now, you want to find (3/4) times (2/5)
Then the distance between 0 and the point you found earlier needs to be divided into four equal parts (because the denominator is 4)
sAnd because we have the factor (3/4), with a numerator equal to 3, we move from the origin 3 of these parts to the right, the point at where you arrived is the point (3/4)*(2/5)
Another way, which should give you the exact same point, is:
First locate the point (3/4) on the number line.
Now, you want to find (3/4) times (2/5)
The distance between zero and the denominator needs to be divided into 5 parts (because the denominator is 5)
Because the numerator is 2, you need to move, from the origin, two of these parts to the right.
The point where you end is the product (3/4)*(2/5)
3. Let a taco's cost be t and the cost of a glass of milk be m:t + m = 2.1, 2t + 3m = 5.15. This is choice D.
4. The only difference is that 4 has been added to the y-value, so the graph remains congruent, but it is moved up along the y-axis, which is choice H.
5. The total number of sandwiches sold is 500, so the fraction of ham-and-cheese sandwiches is 75/500 = 3/20. Since an entire circle is 360 degrees, the fraction for the ham-and-cheese sandwiches is (3/20)(360) = 54 degrees, which is choice C.
Answer:
If i do the math correctly then 7 times 4 = 28, 28 times 2 = 56.
So 56 miles in 2 hours.
