Answer:
1. 2/5
Step-by-step explanation:
When it says the ratio is 5 to 2, that means 5 is always first:
5 : 2 is correct
5/2 is correct
10 : 4 is correct (multiplied 2 on both sides)
2/5 is incorrect because 2 is first. That means that this ratio would be 2 to 5, not 5 to 2.
Answer:
y=1x-2
Step-by-step explanation:
it is parallel so the slope stays the same at 1, and it goes through the point (3, -2), so the y intercept is -2.
Ok so basically it's asking for two numbers that are basically the same except one has a bigger hundreds place. So I'm just going to use a random number.
987,654
and
987,554
Do u see the difference? the second number has 5 in the hundreds place while the first number has 6 in the hundreds name so the first number is bigger.
All angles in a triangle add up into 180. Therefore, if one of them is 90 (the right angle), and the other is 55, you can work out the last angle by doing 180 - 90 - 55 = a.
a = 35 degrees.
Angle b can be worked out by knowing the fact that a straight line has an angle of 180 degrees. We know that angle a is 35, so angle b will be 180 - a, so you do 180 - 35, which is 145 degrees.
b = 145 degrees.
Angle c is the same as angle a (they share a line), so it's 35 degrees too.
