Answer:
The height of the prism is 16 yards
Step-by-step explanation:
To get the height of the prism, we simply divide the volume of the prism by its base area
Mathematically, we have this as;
128/8 = 16 yards
Let the oranges cost = x
Let the apples cost = y
According to given conditions, equation becomes:
.... (1)
.....(2)
Multiplying equation (1) by 8 and equation (2) by 12 to get y
96x+48y=43.04 .... (3)
96x+60y=44.16 .... (4)
Now subtracting both equations we get,
12y = 1.12
y = 0.093
Hence, cost of 1 apple = $0.093
As 12x+6y=5.38
12x+6(0.093)=5.38
12x=4.822
x = 0.40
Hence, cost of 1 orange = $0.40
Answer: Fourth option is correct.
Step-by-step explanation:
Since we have given that
Mean of sample = 65.3
Standard deviation = 5.2
We need to find the 90% confidence interval for the mean.
So, z = 1.64
And the interval would be
Hence, Fourth option is correct.
Answer:
you go this! i ant expain but its mostly false and rue but sorry
Step-by-step explanation:
Let
x----------> length of the long side of rectangle
y---------> length of the short side of rectangle
P----------> perimeter of rectangle
we know that
x=5y-------------> equation 1
P=2x+2y---------> 72=2x+2y---------> equation 2
then
I substitute 1 in 2
72=2*(5y)+2y----------> 72=10y+2y----------> y=72/12---------> y=6
the answer is
the length of the short side of rectangle is 6 m
