I think it's :
Part A ; $30 * (x) + $13
$28 * (x) + $15
Part B ; so $30 * 4 + $13 = $133 vs.
$28 * 4 + $15 = $111 so that would mean company B Would charge the least amount.
Part C ; the difference between company a and company B prices is $22.
three-dimensional graphs wouldn´t give you the right information but two-dimensional graphs would give you the actual size of the shape.
Answer:
x = 9
y = 9√3 = 15.6
Step-by-step explanation:
The triangle given is a right triangle, therefore:
✔️apply trigonometric ratio formula to find x:
Reference angle = 60°
Hypotenuse = 18
Adjacent = x
Thus:
Cos (60) = x/18
Multiply both sides by 18
18×cos(60) = x
9 = x
x = 9
✔️find y by applying pythagorean theorem:
y² = 18² - x² (pythagorean theorem)
y² = 18² - 9² (substitution)
y² = 243
y = √243
y = √(81*3)
y = 9√3 = 15.6
Answer: Histogram
You can eliminate the stem and leaf plot, since it tells you the amount of values.
You can eliminate the dot plot, since it also shows you the number of values.
You can eliminate the frequency table, since it calculates the frequency of a number.
Thus, the answer is the histogram.
