Please give me the correct answer!!!
Neko [114]

Answer:

Step-by-step explanation:

this one is tricky    so b/c the lines are at 90 degees we know that the arcs are similar so set up the parts of the arcs equal to 360 degrees

360 = 130  + 130  + x + x

see each part of the circle ?

then use your mad algebra skilz

100 = 2x

50 = x  

:)  nice.. when I do the math , it seems easy , huh :DDD

If I = PRT/100, MAKE R THE SUBJECT OF THE FORMULA.​
Nonamiya [84]

Answer:

R = \frac{100I}{PT}

Step-by-step explanation:

I = \frac{PRT}{100} ( multiply both sides by 100 to clear the fraction )

100I = PRT ( isolate R by dividing both sides by PT )

\frac{100I}{PT} = R

oksian1 [2.3K]

Answer:

Step-by-step explanation:

Hello!

The variable of interest is

X: mark obtained in an aptitude test by a candidate.

This variable has a mean μ= 128.5 and standard deviation σ= 8.2

You have the data of three scores extracted from the pool of aptitude tests taken.

148, 102, 152

The average is calculated as X[bar]= Σx/n= (148+102+152)/3= 134

I hope this helps!

Can someone please answer this multiple choice questions numbers 2 , 12 and 13 please answer and please please show work
Vinil7 [7]

Answer:

2) D

12) C

13) D

Step-by-step explanation:

2)     4° C at 6:00 PM

     

A)  + 2°  - 6° = - 4°          4°  -  4°  = 0°       0° does not equal 4°        A  \neq Correct

B)   - 5°  + 1° = - 4°           4°  -  4°  = 0°       0°  does not equal 4°      B  \neq Correct

C)  + 6° - 4° =  + 2°          4° + 2° = 6°           0° does not equal 4°      C  \neq Correct  

D)  - 7°   + 7° = 0°            4°  + 0°  = 4°          4°  does equal 4°           D = Correct

The answer to question #2 is D

12)  M = -3

N ---->  M = 8.5 units

The only possible options for N are:

-3 + 8.5 = 5.5

-3 - 8.5 = -11.5

-11.5 is not a choice, so the answer to question #12 is C

13)  Scale: 1 inch = 70 yards

Abe walks 3.5 inches (on the diagram)

Multiply both sides of the scale by 3.5

3.5 * 1 inch = 70 * 3.5

3.5 inches = 245 yards

Abe walked 245 yards

The answer to question #13 is D

Hope this helps :)
