What is the height of the trapezoid?
The area of the trapezoid is given by the formula A= (a+b)/ 2 * h
in this question a= 8, b= 10, A= 108 inches², and h is what we have to find, substitute what we have got into the formula and you will have:
108= (8+10) /2 *h
108= 9 *h
h= 108/9
h= 12 inches
a).100 b).150 c).175 d).200 e).250
2. 4x+16y=-19, -8x+2y=10
3. 2x+6y=-2, -x+2y=6
4. -8x-y=-13, 5x-3y=-10
5. -4x+6y=4, -x+8y=1
6. -x+y=-5, 7x-3y=23
7. -9x-5y=26, 4x-4y=-24
Answer:
Step-by-step explanation:
Cm : km
1 : 2.3
x : 69 Cross multily
2.3x = 69
x =
x = 30cm
the distance between the two towns on the map is 30cm
Answer:
30 cm
Step-by-step explanation:
69/2.3 = 30
