Answer:
If Oscar the ostrich travels 126 miles in 3 hours . that means he travels 42 miles in 1 hour. so 42mph
Answer:
x = 120
y = 30
Step-by-step explanation:
Given that RST is equilateral, each of its interior angles will be 60 degrees
Looking at x, it lies on a starting line with one of the interior angles of RST
The sum of angles on a straight line is 180
Thus;
x + 60 = 180
x = 180-60
x= 120
Looking at triangle RSU, the markings indicates that we have an isosceles triangle
For an isosceles triangle, the base angles are equal in value
This means that SRU is also y
Mathematically, the sum of angles in a triangle is 180
Hence;
x + y + y = 180
x + 2y = 180
120 + 2y= 180
2y = 180-120
2y = 60
y = 60/2
y = 30
4 = (-8) + 3x
Firstly, you can rearrange the equation to make it easier to read:
3x - 8 = 4
Add 8 on both sides to isolate the x:
3x = 12
Divide both sides by 3:
x = 4
Answer:
Your answer is 61.
Step-by-step explanation:
Simple enough! We simply round up each cost to the nearest whole dollar. $6.50 can be rounded to $7, $15.75 can be rounded up to $16, $2.25 can be rounded up to $3 (Note we're rounding up, in normal rounding we would round down to $2). Finally, $7.25 can be rounded up to $8.
Next comes simple algebra,
Therfore, your overestimate of the cost would be 61.
