Answer:
for the -4-2y=28
Step-by-step explanation:
you would add 4 to the other side to be -2y=28+4 then divide the whole equation by -2 so it would be y = -14 - 2
that all i know
The two numbers would be 36 and 56
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.
<h3>The distance between the pair of points is 2.8 units</h3>
<em><u>Solution:</u></em>
Given that,
Points are W(2, 5), U(4, 3)
<em><u>Distance between two points is given as:</u></em>
From given,
<em><u>Substituting the values we get,</u></em>
Thus the distance between the pair of points is 2.8 units
Answer:
B = 42.7 degrees, C = 102.3 degrees and c = 18.7.
Step-by-step explanation:
We use the Sine Rule:
a / sin A = b / sin B
11 / sin 35 = 13 / sin B
11 sin B = 13 sin 35
sin B = 13 sin 35 / 11 = 0.677863
B = 42.7 degrees.
So C = 180 - 42.7 - 35
= 102.3 degrees.
c / sin 102.3 = 11 / sin 35
c = 11 sin 102.3 / sin 35
= 18.7.
