Answer:
90 seconds
Step-by-step explanation:
To find the time it takes to take a certain amount of steps, divide the given rate by the time.
3/2 = 1.5
This means she takes 1.5 steps every second. Now, we can multiply this rate by 60 to find how far she will go in that time.
1.5 · 60 = 90
Bethany takes 90 steps in 60 seconds.
I hope this helps ^^ Good luck
Answer:
A. 9.6
B. √92
Step-by-step explanation:
<h3>A.</h3>
Rational: 9.6. It is rational because it is a terminating decimal number.
__
<h3>B.</h3>
Irrational: √92 ≈ 9.59166.... It is irrational because it is the square root of an integer that is not a perfect square. All such square roots are irrational.
_____
<em>Additional comment</em>
In general, the n-th root of an integer that is not a perfect n-th power will be irrational. For example, ∛885 ≈ 9.600954766... is irrational, because 885 is not a perfect cube. (9³=729, 10³=1000)
Trig functions of (non-zero) rational angles in radians will be irrational. For example, tan(1.467) ≈ 9.5996286... is irrational.
Answer:
13x+14
Step-by-step explanation:
2(3x+4)+6+7x
Distribute:
=(2)(3x)+(2)(4)+6+7x
=6x+8+6+7x
Combine Like Terms:
=6x+8+6+7x
=(6x+7x)+(8+6)
=13x+14
Answer: x = 2y
Step-by-step explanation:
Let's solve for x.
2(3x+4y)=4x+12y
Step 1: Add -4x to both sides.
6x+8y+−4x=4x+12y+−4x
2x+8y=12y
Step 2: Add -8y to both sides.
2x+8y+−8y=12y+−8y
2x=4y
Step 3: Divide both sides by 2.
<u>2x
</u>
2
=
<u>4y

x=2y
Answer:
x=2y
