The area of the parallelogram is 40 centimeters
Answer:
-82/3
Step-by-step explanation:
first divide -8/9 by -2/3
-8/9 ➗ -2/3 =-8/9*3/-2 =4/3
multiply 4/3 by -41/2
4/3*-41/2 = -82/3
Answer:
cos 30° =767.6/hypotenus
(make h the subject of the formular)
h = 767.6/cos 30°
h =767.6/0.154
h =4,985
approximately 5,000
Answer:
A
Step-by-step explanation:
6 x 6 = 36
10 x 10 = 100
Let one of the number be x and the other be y
<span>two times the first number plus the second number is 41
</span>2x + y = 41
<span>the first number plus three times the second number is 73
x + 3y = 73
</span>2x + y = 41 --------- (1)
x + 3y = 73 --------- (2)
From (1):
2x + y = 41
y = 41 - 2x ------- sub into (2)
x + 3(41-2x) = 73
x + 123 - 6x = 73
x -6x = 73 - 123
-5x = -50
x = 10 -------- sub into (1)
2 (10) + y = 41
20 + y = 41
y = 41 - 20
y = 21
Ans: x = 10, y = 21
