Answer:
-0.4 should be in between 0 and -0.5, however be as close to -0.5 as possible while not being ON -0.5.
3 4/5 should be in between 3 and 4, so you can split 4/5 into 8/10 which are equal to each other. Then you can pretend to split the 3 and 4 gap into 10 equal pieces. After you split the gap, count 8 parts to the left of 3.
Step-by-step explanation:
I hope you understand what I mean.
Let the smaller number be x
The bigger number is 5x
5x(x) = 180
5x² = 180
x² = 180÷5
x²=36
x=√36
x = 6
x=6
5x = 6 x 5
5x = 30
So the two numbers are 6 and 30
Answer:
4
Step-by-step explanation:
Two ways to solve this - either divide 140 by 35 (140/35 = 4)
or keep adding 35 until you reach 140: 35+35+35+35 = 140
Answer:
at y = 18 units
Step-by-step explanation:
An arch has the equation y=-2/81x^2+18. Find it’s maximum height
This is a parabolic function
Maximum at the vertex
x = -0/(2*(2/81)) = 0
max at y = 18 units
The answer is -3 because
-|28|= -28 now the problem looks like -28+(-5)^2
(-5)^2=25
-28 +25= -3
