What is the greatest common factor of these? 27y^7x^8w^4 and 18y^3w^6

1 answer:

3 0

First, look at the coefficients. They are 18 and 27, which means the final answer will have the coefficient of 9, since its the GCF in between them.

Look at the xs. Since there aren't any in the second expression, it's not part of the answer.

Now, look at the ys.
The GCF in between y^7 and y^3 is y^3.

Finally, look at the ws.
The GCF in between w^4 and w^6 is w^4.

Put them all together, and the answer is 9y^3w^4

Hope this helps!

Co linear points have same slope
Points (1,3), (-4,7), and (-29,K)
m1,2=7-3/-4-1=-4/5

m2,3=K-7/-29+4
m2,3=K-7/-25

-4/5=K-7/-25
4/5=K-7/25
4=K-7/5
20=K-7
K=27

Eduardo and Paul are leaving the same airport in Florida. Eduardo’s flight to Jamaica is 273 miles long. Paul's flight to Hondur

k0ka [10]

Answer:

B. 41.8° is the correct answer

Step-by-step explanation:

We are given that,

Length of Eduardo's flight path = 273 miles

Length of Paul's flight path = 357 miles

Distance between their destinations = 238 miles.

Now, using the law of cosines, we get,

$238^2=273^2+357^2-2\times 273\times 357\times \cos \theta$

i.e. $56644=74529+127449-194922\times \cos \theta$

i.e. $56644=201978-194922\times \cos \theta$

i.e. $194922\times \cos \theta=145334$

i.e. $\cos \theta=0.7456$

i.e. $\theta=\arccos 0.7456$

i.e. θ = 41.8°

Hence, the angle between their flight paths is 41.8°.

Can someone help me with is and please explain thanks

Andrew [12]

The answer is b because the pattern of these terms r that odd numbers r positive and even numbers are negative. 50 is even so it is negative, while 51 is odd so it is positive. Remember that negative numbers are below zero. If u add something to a negative number it is like subtracting positive numbers. -51+50 is -1. Because if 51 was positive it would be 51 minus 50. The answer is b. If u dont understand or if it is wrong tell me. :D

Wesley Estimated 5.82-4.21 to be about 2. Is this an overestimate or an underestimate?

Bezzdna [24]

I'd say neither because 5.82-4.21 equals to 1.61, and it does not go above 2 as an overestimate. In addition, it's not an underestimate because 1.61 rounds up to 2. If you can't put that as an answer, you can say its an underestimate because it does not meet the real standards of being 2.

Solve the following, round the solution to the nearest tenth. 57.7r + 23.23 =2.57

Ann [662]

57.7r + 23.23 =2.57

Subtract 23.23 from both sides:

57.7r = -20.66

Divide both sides by 57.7

r = -20.66 / 57.7

r = -0.358

round to nearest tenth = 0.4
