3 equivalent ratios can be:
4/10
6/15
8/20?
Answer:
B choice
Step-by-step explanation:

where m = slope and b = y-intercept.
The value of m is 3/4. That means slope is 3/4. Changing 3/4 to - 3/4 will make the slope become negative. Therefore the answer is B.
It makes a 74 degree angle.
The sides of the triangle that are given are the side adjacent to the angle the ladder makes with the ground and the hypotenuse of the triangle.
adjacent/hypotenuse is the ratio for cosine:
cos x = 7/25
To solve this, we will take the inverse cosine:
x = cos⁻¹(7/25) = 73.7 = 74
Answer:
570 miles
Step-by-step explanation:
If Damian rides 38 each week and we want to know how much it was for 15 weeks, then we just multiply the two to get 570 miles in a 15 week period.
Answer:
A. 10 ft
Step-by-step explanation:
Since dimensions of the wall are similar to the dimensions of the window.
Therefore, lengths and widths of wall and window would be in proportion.
So,
