Answer:15
Step-by-step explanation:
Answer:
22 × = 125 .71
Step-by-step explanation:
22 ×
={[ ( 22 × 7) + 6] ÷ 7 } ×
= ×
=
=
= 125 .71
You can solve this by finding all of the factors of 28 and seeing which ones add up to 22 when doubled.
The factors of 28 are as follows:
28 x 1 28(2) + 1(2) = 56 + 2 = 58 ≠ 22
14 x 2 14(2) + 2(2) = 28 + 4 = 32 ≠ 22
7 x 4 7(2) + 4(2) = 14 + 8 = 22
The dimensions of the rectangle are 4 x 7.
Answer:
sinQ=cosR
Step-by-step explanation:
First we need to find out the measure of ∠R.
The sum of all the angles in a triangle add up to 180. Therefore:
∠Q+∠R+∠S=180
66+∠R+90=180
∠R=180-156
∠R=24°
Since ∠Q≠∠R, sinQ≠sinR. So the first option is incorrect - let's try the second one.
sinQ=cosR
sin66=cos24
0.9135454576=0.9135454576
So the second equation is the correct relation.
6/0.25 = 24
1/0.9 = 1.11111111111...........
8/0.75 = 10.6666666666666.........
8/0.7 = 11.428571..........
2/0.4 = 5
1/ 1/6 = 6
9/ 0.75 = 12
6/0.8 = 7.5
