To find the unit rate you need to take the amount and divide it by the weight. In this case 2.99/14 = $0.214/lb
Answer:
a = 5.2 units, c = 11.1 units to the nearest tenth.
m < A = 27 degrees.
Step-by-step explanation:
c / sin 100 = 9 / sin 53
c = 9 * sin 100 / sin 53
c = 11.098.
m < A = 180 - 153 = 27 degrees.
a / sin 27 = 9 / sin 53
a = 9 * sin 27 / sin 53
a = 5.166.
Answer:
x = 53
Step-by-step explanation:
The angle labeled with the expression "2x - 20 " and the angle with the measure of 86 degrees are opposite interior angles.
Opposite interior angles are congruent
This means that 2x - 20 = 86
This is our equation.
We now solve for x using basic algebra
2x - 20 = 86
step 1 add 20 to each side
-20 + 20 cancels out
86 + 20 = 106
now we have 2x = 106
step 2 divide each side by 2
2x / 2 = x
106 / 2 = 53
we're left with x = 53
Answer:
The value of y is 89.55 at x=15 and 60.69 at x=9.
Step-by-step explanation:
The equation of best fit line is
where, y is scores of two students after x working hours.
We need to find the score after 15 and 9 hours.
Substitute x=15 in the given equation.
Substitute x=9 in the given equation.
Therefore, the value of y is 89.55 at x=15 and 60.69 at x=9.
