In 8-10, a teacher gave a test with 50 questions, each worth the same number of points. donovan got 39 out pf 50 questions right. marcci score was 10 percentage points higher than donovan's. what was marcis score? explain. how many more questions did marci answer correctly.

Marcis answered 44 questions correctly that was 5 more than Donovan.

Step-by-step explanation:

Teacher gave a test paper with 50 questions, each worth the same number.

Donovan got 39 points out of 50 points.

Percentage marks that Donovan got =

=

= 78%

If Marcis scored 10% more then his percentage of marks will be = 78 + 10 = 88%

Now we will calculate the marks Marcis obtained.

Since 88% means, out of 100 marks Marcis scored 88 but the test paper was of total 50 marks then the marks scored by Marcis will be

=

= 44

Marcis scored more than Donovan = 44 - 39 = 5

9) i can't see the angle so whatever it is just do this: cos(angle) x hypotenuse and then use that answer and they hypotenuse and plug it into this: (answer you just got)^2 + b^2 = (hypotenuse)^2. the first answer will be the answer of the adjacent side and the second answer after this equation will be the opposite side.

10) y = 14 x = √147 or 12.12435565

11) x = 4.8

12) x = 4.2

13) x = 9.3

14) pq: 13.2

qr : 17.6

angle p: 53º

15) angle c: 54.3º

angle a: 35.7º

16) h = 21040

v = 1841

step-by-step explanation:

10) 7/sin(30) = 14 = y

7^2 + b^2 = 14^2

49 + b^2 = 196

b^2 = 196 - 49

√b^2 = √147

x = √147

11) cos(70) x 14 = 4.788282007

x = 4.8

12) tan(25) x 9 = 4.196768923

x = 4.2

13) sin(31) x 18 = 9.270685348

x = 9.3

14) pq: sin(37) x 22 = 13.23993051

pq: 13.2

qr: cos(37) x 22 = 17.56998122

qr : 17.6

angle p: 180 - (37 + 90) = 53º

15) cos-1(7/12) = 54.31466529

angle c: 54.3º

angle a: 180 - (90 + 54.31466529) = 35.68533471

angle a: 35.7º

16) 4 x 5280 = 21120

cos(5) x 21120

h = 21039.63202

h = 21040

sin(5) x 21120

v = 1840.729287

v = 1841
