Hello! I can help you!

12. Okay. 16 1/5 is 16.2 in decimal form. Let’s subtract both numbers. 19.8 - 16.2 = 3.6. Paloma is 3.6 seconds faster than Savannah in the 100m dash.

13. Two lengths that are within the given span of 0.08 and 0.4 are 0.22 and 0.17. 0.22 as a fraction in simplest form is 11/50 and 0.17 as a fraction in simplest form is 17/100.

Does anyone know what the simplest form is? Will give brainiest

Hello from MrBillDoesMath!

Answer:

Choice B.

Discussion:

From the first step

324 x^6 y^ 8 =

2^2 * 3^4 * x^2 * x^4* y^8

so the fourth root of this is

2 ^(2/4)* 3^(4/4) x^(2/4)* x^(4/4)*y^(8/4) =

2^ (1/2) * 3^1 * x^(1/2) * x^(1)* y^ (2) =

(2x)^(1/2) * 3 * x * y^2 =

3 * x * y^2 * sqrt(2x) =

3 * x * y^2 * ( (2x)^2) ^ (1/4)) =

3 * x * y^2 * (4x^2) ^ (1/4)

which is choice B

Thank you,

MrB

1. 4x=3y+3, 6y= 8x+ 36.

GaryK [48]

4x=3y+3 and 6y= 8x+ 36 and y=3x-1 and y= 6- x/3

4x=3y+3 and 6y= 8x are parallel and y=3x-1 and y= 6- x/3 are perpendicular.

Format of my answer:

[Problem letter] Parallel Lines

- Converse / Reason

!! I am not sure which / what converses you are using, but I gave the reasoning for it. If you see something similar, use the converses you know !!

[a] j & k

- If two lines intersected by a transversal form congruent alternate interior angles, then the lines are parallel

[b] m & n

- If angles are supplementary in this placement, the lines are parallel

[c] l & n

- If angles are equal when they are corresponding, the lines are parallel

[d] l & m

- If two angles that are congruent are vertical, the lines are parallel

[e] j & k

- If two lines intersected by a transversal form congruent corresponding angles, then the lines are parallel

[f] l & n

- If angles are supplementary in this placement, the lines are parallel

[g] l & n

- If two angles that are congruent are vertical, the lines are parallel

[h] -------

[i] l & n

- If two angles that are congruent are vertical, the lines are parallel

[j] -------

[k] -------

[l] j & k

- If two lines intersected by a transversal form congruent corresponding angles, then the lines are parallel

[m] -------

[n] j & k

- If angles are supplementary in this placement, the lines are parallel

[o] -------

-> See attached for more information

Have a nice day! - hopefully these are mostly correct, been awhile since I've done this

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

klasskru [66]

To find LCM
factor and eliminate ones already represented
1=1
2=2
3=3
4=2*2
5=5

1*2*2*3*5=60
