Which graph shows the line of best fit for the data ?

172.7=3.14d Solve for d

Serga [27]

Answer:

55

Step-by-step explanation:

Divide both sides by 3.14 to get d by itself.

172.7 / 3.14 = 55 = d

Pls help Given: △ABC, CM⊥ AB, BC = 5, AB = 7 CA = 4 sqrt(2) Find: CM

babymother [125]

Answer:

The general plan is to find BM and from that CM. You need 2 equations to do that.

Step One

Set up the two equations.

(7 - BM)^2 + CM^2 = (4*sqrt(2) ) ^ 2 = 32

BM^2 + CM^2 = 5^2 = 25

Step Two

Subtract the two equations.

(7 - BM)^2 + CM^2 = 32

BM^2 + CM^2 = 25

(7 - BM)^2 - BM^2 = 7 (3)

Step three

Expand the left side of the new equation labeled (3)

49 - 14BM + BM^2 - BM^2 = 7

Step 4

Simplify And Solve

49 - 14BM = 7 Subtract 49 from both sides.

-49 - 14BM = 7 - 49

- 14BM = - 42 Divide by - 14

BM = -42 / - 14

BM = 3

Step Five

Find CM

CM^2 + BM^2 = 5^2

CM^2 + 3^2 = 5^2 Subtract 3^2 from both sides.

CM^2 = 25 - 9

CM^2 = 16 Take the square root of both sides.

sqrt(CM^2) = sqrt(16)

CM = 4 < Answer

scoundrel [369]

Answer:

2664.3

Step-by-step explanation:

The volume of a sphere is

V = 4/3 πr³

Multiply the radius (which is the diameter divided by 2), 8.6 by itself 3 times, and them multiply it by pi and 4/3 to achieve a volume of 2664.31 or aproximatley 2664.3.

A tiling company completes two jobs. The first job has $1200 in labor expenses for 40 hours worked, while the second job has $15

artcher [175]

The closest i can think of that makes since is 1560=30(52)+b, mainly because
30 x 52 = 1560 so that's what i think it is and if im wrong sry.

Shaka and ajani playa a game shaka scores 30%of maximum points and misses the record by 15 points ajani gets 40% of maximum pint

stellarik [79]

Step-by-step explanation:

First, we should focus on their records and percents.

Shaka: 30%, -15 points.

Ajani: 40% +35 points.

When we subtract 35 and -15, we get the difference of 50.

We know 10% is 50 point difference, 20% is 100 point difference, 30% is 150 point difference, etc.

But that's not correct.

It has to be in the Negatives.

It cannot be positive under 30%.

Since 30% is -15 points, we subtract 50 for 20%, then another 50 for 10%.

Our Correct work is:

0% = -0, 10% = -115, 20% = -65, (30% = -15, 40% = 35.)

- We are correct.

Then, since we are correct, we keep going.

30% = -15, 40% = 35, 50% = 85, 60% = 135, 70% = 185, 80% = 235, 90% = 285, 100% (Or Maximum Point): 335.

Therefore, the Maximum Point is 335 points.

Best of Luck to you!
