LAST ONE \small \angle L and \small \angle M are supplementary, \small m\angle L=12x+45 and \small m\angle M=18x-30. Determine t
FinnZ [79.3K]

Answer:

m\angle L = 111\degree \\m\angle M = 69\degree

Step-by-step explanation:

Since, angle L and angle M are supplementary.

\therefore m\angle L + m\angle M= 180\degree  \\ \therefore \: 12x + 45 + 18x - 30 = 180 \degree \\ \therefore \: 30x + 15= 180 \degree\\ \therefore \: 30x= 180 \degree - 15 \degree\\ \therefore \: 30x= 165 \degree  \\ x =  \frac{165 \degree}{30}  \\ x = 5.5 \degree \\  \\ m\angle L  = 12x + 45  \\ m\angle L = 12 \times 5.5 + 45 \\ m\angle L  = 66 + 45 \\ \huge \red{ \boxed{ m\angle L  = 111 \degree}} \\  \\ m\angle M=18x - 30 \\ m\angle M=18 \times 5.5 - 30 \\ m\angle M=99 - 30 \\ \huge \purple{ \boxed{ m\angle M=69 \degree}} \\

Why might algebra tiles not be a good tool to use to factor x² + 18x +80
anyanavicka [17]

Answer:

Algebra tiles would not be a good tool to use to factor because you would need to drag an x-squared tile, 18 x-tiles, and 80 plus tiles and  it would take a lot of time to drag that many tiles on the board and there might not be enough space to hold all of them. and do u have time to drag 80 tiles? lol

Helpppp Pleaseeeeee!!!!!
inysia [295]

Hi there,

I’m attaching the same image with more information on the graph.

The 4th mark (the middle dashed line) is marking the mean (70).

The 3rd and the 5th are marking the mean less/plus 1 deviation.

So, 70.5 is the 5th mark.

Taking this into account:

The probability of selecting a container that has less than 70.5 is 0.1% + 2.2% +13.6% 34.1% + 34.1% = 84.1%

The probability of choosing more than 70,5 = 13.6% + 2.2% +0.1% = 15.9%

Good Luck!

Solve the following multiplication problem.<br><br> 11 cu. yd. 17 cu. in. × 135
Gekata [30.6K]

Answer:

69,286,455 cu inches

Step-by-step explanation:

<u>Step 1: Convert yards to inches</u>

1 cu yard = 46656 cu inches

11 cu yard = y cu inches

<em>Cross multiply</em>

y = 11 x 46656

y = 513216 cu inches

<u>Step 2: Find total inches</u>

513216 + 17 = 513233 cu inches

<u>Step 3: Multiply total inches by 135</u>

513233 x 135 = 69,286,455 cu inches
