d) Another student answers 21 questions.
6 are correct. How many points does she score?

A = 75 points

B = -50

C = 0 Points

D = -20

Step-by-step explanation:

C)

10 time 3 = 30

minus 10 (because he only got 10 right) =20

minus another 20 because he only answered 15 = 0

C = 0 Points

D)

6 times 3 = 18

19 wrong = 38

-38 - 18 = -20

D = -20

answer:  

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
