Answer:
Cost per Electricity Unit= $0.61
Cost per Gas Unit= $0.22
Step-by-step explanation:
Suppose,
Cost per Electricity Unit: e
Cost per Gas Unit: g
for the first month condition, equation would be
![600*e+100*g=388...........................................(i)](https://tex.z-dn.net/?f=600%2Ae%2B100%2Ag%3D388...........................................%28i%29)
and for the next month condition, equation would be like
![400*e+150*g=277...........................................(ii)](https://tex.z-dn.net/?f=400%2Ae%2B150%2Ag%3D277...........................................%28ii%29)
By solving both linear equations simultaneously, we get
e=0.61 and g=0.22
Answer:
When y = 5; x = 2
Step-by-step explanation:
What we have to do here is to first go to the point y = 5 on the y-axis
Now, the next thing is to trace this to the plot
The tracing will meet the plot at a point
At this point, we can now drop a line to the x-axis
By this, we can get that at y = 5; then x = 2
Now, we want to check the validity from the linear equation given
That would be;
y = -x + 7
y = -2 + 7
y = 5
This holds according to the linear equation given
Answer:
1/64
Step-by-step explanation:
10 = ½
20 = ¼
30 = ⅛
40 = 1/16
50 = 1/32
60 = 1/64
Step-by-step explanation:
4x + 2 + 3x + 3 = 180 (straight angle)
4x + 3x + 2 + 3 = 180
7x + 5 = 180
7x = 175
x = 25°
Answer:
0.25
Step-by-step explanation:
A man who is a taster and has a non-taster mother can only be heterozygous (Tt) for the trait since his mom is homozygous recessive (tt).
A man who is a taster marries a woman who is a taster with five siblings, three of whom are non-tasters. Thus the woman can be said to be to be heterozygous. This is because, for her parents to be able to produce her non- tasters siblings, both have to have one copy each of the recessive allele (t) and since she is a taster (T), it means one or both of her parents possess one copy of the dominant trait (T). This accounts for her being an heterozygote (Tt).
the man who is Tt marries a woman who is also Tt. Chances that the children of this marriage will be non-tasters will be 1/2 x 1/2 = 1/4 = 0.25
