Answer:
Let's solve your system by elimination.
3x+4y=29;6x+5y=43
Multiply the first equation by -2,and multiply the second equation by 1.
−2(3x+4y=29)
1(6x+5y=43)
Becomes:
−6x−8y=−58
6x+5y=43
Add these equations to eliminate x:
−3y=−15
Then solve−3y=−15for y:
−3y=−15
−3y
−3
=
−15
−3
(Divide both sides by -3)
y=5
Now that we've found y let's plug it back in to solve for x.
Write down an original equation:
3x+4y=29
Substitute5foryin3x+4y=29:
3x+(4)(5)=29
3x+20=29(Simplify both sides of the equation)
3x+20+−20=29+−20(Add -20 to both sides)
3x=9
3x
3
=
9
3
(Divide both sides by 3)
x=3

Answer:
The distance for a waggle duration of 4.6 is 51,002.68 units.
Step-by-step explanation:
We are given the following in the question:
The above equation is a regression equation for estimating distance for a waggle duration and x is the duration.
We have to estimate the distance for a waggle duration of 4.6
Putting x = 4.6
Thus, the distance for a waggle duration of 4.6 is 51,002.68 units.
Answer:
The radius is 31.83m
Step-by-step explanation:
200m is the circumference and the formula for circumference is C=2πr. So 200=2πr. Solve for r (radius) by dividing 2π on both sides to get rid of the 2π. so basically 200/2π= 2πr/2π ... the 2π cancel from the left side and you are left with r= 200/2π, now plug that into the calculator and you will find the radius. r=200/2π which should equal 31.83 meters.
Answer:
2 x 0 = 0
Any number multiplied by 0 equals 0.
Step-by-step explanation:
If multiplication tells you how many times to add a certain number, then multiplying by 0 means that you have nothing to add because 0 means nothing. So, 3 x 0 means that you are adding 3 zero, or no, times. ... You get 0 because you're still not adding anything. Nothing added to nothing is still nothing.
