Answer:
B. m∠b + m∠d + m∠e = 180°
(Total angle in a triangle)
C. (m∠a + m∠b) - m∠d = m∠b
(Alternate angles)
E. (m∠a + m∠b + m∠c) = (m∠b + m∠d + m∠e)
(Supplementary angles)
Answer:
70
Step-by-step explanation:
You have to use ratios. If 5 of 12 members bought water, then x of 168 members will buy water.
70 members will buy bottled water.
<span>X/9=-5
First: To get your x alone, and to get rid of your fraction you would multiply each side by 9.
You would get: x=-45 <That would be your answer

Answer:
135°
Step-by-step explanation:
Interior angle= (n-2)/n ×180°
n= no. of sides
so,
putting the value of n which is 8
(8-6)/8 × 180
=135°
1 yard = 3 feet = 36 in
so 1 in = 1/36 yard, 1 ft = 1/3 yard.
The volume of the layer of the topsoil, is:
5 in * 23 ft * 17 ft = 5 *(1/36)*23*(1/3)*17*(1/3) yard cubed =
(5*23*17)/(36*3*3)= 1955/324=6.034 yard cubed.
The store only sells increments of 1/4 = 0.25 cubic yards.
we need 6.034/0.25=24.136
So we need to buy 25 (24 will not be enough) increments of 1/4 cubic yards.
Answer: 25 increments of 1/4 cubic yard, that is 25*0.25=6.25 cubic yards.
