Let the speed of the current be y and the speed of Micah's sailing speed be x. Then 4.48/(x + y) = 0.32
4.48/(x - y) = 0.56
0.32x + 0.32y = 4.48 . . . (1)
0.56x - 0.56y = 4.48 . . . (2)
(1) x 7 => 2.24x + 2.24y = 31.36 . . . (3)
(2) x 4 => 2.24x - 2.24y = 17.92 . . . (4)
(3) - (4) => 4.48y = 13.44
y = 3
From (1), 0.32x + 0.32(3) = 4.48
0.32x = 4.48 - 0.96 = 3.52
x = 3.52/0.32 = 11
Therefore, the speed of the current is 3 miles per hour. Answer is 3 miles per hour
Answer: Interest rate is $360.00
Step-by-step explanation:
Equation:
I = Prt
P= $600.00
R= 2%
T= 30
I = 600 × 0.02 × 30 = 360
I = $ 360.00
The simple interest accumulated
on a principal of $ 600.00
at a rate of 2% per year
for 30 years is $ 360.00.
The equation in slope-intercept form is:
y=4x-23
Step-by-step explanation:
The given equation is:
The given equation is in point-slope form. we have to convert it to the slope-intercept form.
the slope intercept form is:
So,
Subtracting 3 from both sides
The equation in slope-intercept form is:
y=4x-23

Answer:
It is the one you have selected. "The exact number of children on the playground each day."
Step-by-step explanation:
The stem and leaf plot shows each amount of children specifically. The histogram has the ages in groups. The stem and leaf plot is more specific and shows the inside information while the histogram only shows the number of children and frequency put in groups. I also took the quiz and got this right.
Hope this helps! Make sure to give me brainiest if somebody else answers.
