“Three decimal places” is the same as “the nearest thousandth.” So, for example, if you are asked to round 3.264 to two decimal places it means the same as if your are asked to round 3.264 to the nearest hundredth. Some questions, like the example below, will ask you to “show your answer correct to two decimal places."
A triangle interior angles add up to 180
so we have 3:4:5
the ratio of the angles
3+4+5=12
therefor 180=12 units
divide by 12
15=1 unit
subsitute
find the smallest unit
3
3 times 15=45
answer is 45 degrees
Answer:
3
Step-by-step explanation:
Answer:
1.14 days (approximately)
Step-by-step explanation:
Family drives 350 miles per day
Let d = days
Equation: 350d = 400
d = 400/350
d is approximately 1.14 days
If you want to answer it without decimals, you should say around 2 days since it's going to take more than one day to travel.
I already answered this question, if you look back in your questions you should find this answered along with another one. I'll do it again just in case you don't find it.
Answer:
{y,x} = {-4,-2}
Expanation:
Solve by Substitution :
// Solve equation [1] for the variable y
[1] y = 2x
// Plug this in for variable y in equation [2]
[2] -2•(2x) - 8x = 24
[2] - 12x = 24
// Solve equation [2] for the variable x
[2] 12x = - 24
[2] x = - 2
// By now we know this much :
y = 2x
x = -2
// Use the x value to solve for y
y = 2(-2) = -4
