Answer:
Step-by-step explanation:
Add them all up 15 if one is taken out and no replaced OR put back in, then the second draw will have 14 beads.
4 x 6 = 24
15 x 14 = 210
Answer:
∠a = <u>51°</u>
∠b = <u>48°</u>
∠c = <u>70°</u>
Step-by-step explanation:
∠c = 180° - 110° = <u>70°</u> (Angles on a straight line add up to 180°)
∠ADB = 180° - (110° + 19°) = <u>51°</u> (Angles on a triangle add up to 180°)
∴ ∠a = <u>51°</u> (Alternate angles are equal)
∠A = 180° - (51° + 62°) = <u>67°</u> (Angles on a triangle add up to 180°)
∠CAB = 67° - 19° = <u>48°</u>
∴ ∠b = <u>48°</u> (Alternate angles are equal)
Answer:
r <5 u do 31-6 than divided by 5r
Step-by-step explanation:
1. first multiply -1 times all elements of matrix A
2. then multiply 1/3 by all elements of matrix B
3. then add each corresponding entries to get the result.
from step 1. matrix A will be
-4 -2. -1. -3
-2. 0. 1. -3
step 2. matrix B will be
3. -1. -2. -4
3. -10. 10. -1
add each corresponding elements to get
-1. -3. -3. -7
1. -10 11. -4
