Answer:
1st pic) 17.8
2nd pic) 16.8
3rd pic) 9.1
4th pic) 13.5
Step-by-step explanation:
<u>1st pic:</u> 
(write equation) Cos 27 (cos 27 = 0.89) = 
(new equation) 0. 89 =
(multiply 20 on both sides) 0.89 x 20 = x 20
(solve) 17.8 = x
<u>2nd pic:</u> 
(write equation) tan 40 (tan 40 = 0.84) = 
(new equation) 0.84 =
(multiply 32 on both sides) 0.84 x 20 = x 20
(solve) 16.8 = x
<u>3rd pic:</u>
(write equation) cos 55 (cos 55 = 0.57) = 
(new equation) 0.57 =
(multiply 16 on both sides) 0.57 x 16 = x 16
(solve) 9.1 = x
<u>4th pic:</u>
(write eqaution) tan 42 (tan 42 = 0.90) = 
(new equation) 0.90 =
(multiply 15 on both sides) 0.90 x 15 = x 15
(solve) 13.5 = x
Answer:
she put them in at 2:45
Step-by-step explanation:
because 35 minutes before 3:20 is 2:45
Answer:
Step-by-step explanation:
Using the formula for finding the circumference of a circle.
C = 2πr
r is the radius
radius = diameter/2
radius = 10/2
radius = 5in
C ,= 2(3.14)(5)
C = 20(3.14)
C = 31.4×2
C = 62.8in (for 1 rotation)
For 16 rotations;
C = 16×62.8
C = 1004.8in
The distance covered is 1004.8in
Answer:
x = 0
Step-by-step explanation:
3 x -1 = -3 and 3 x -8x = -24x
-3 + 3( the opposite of the -3 given in the parentheses) = 0
-24x = 0
0/-24 (from -24x)= 0
x = 0
Answer:
3/20
Step-by-step explanation:
Given that :
Share for 5 persons = 3/4 of a whole pizza
Each person gets an equal size of the share :
Hence, share per person :
Portion of pizza / number of persons
3/4 ÷ 5
3/4 * 1/5
= (3*1) / (4*5)
= 3/20
