Answer:
$15.75
Step-by-step explanation:
y × 100 = 5 × 15
100y = 75
100y ÷ 100 = 75 ÷ 100
y = 0.75
$15 - $0.75
$14.25
y × 100 = 10 × 15
100y = 150
100y ÷ 100 = 150 ÷ 100
y = 1.5
$14.25 + $1.50
$15.75
I kind-of need more specifics here. You didn't give any dimensions, but okay. So if you notice, from the side, any cone just looks like a regular old triangle. And we can treat it like one when trying to find the slant height. Ever heard of the Pythagorean theorem? a squared plus b squared = c squared. so in this case, the hypotenuse, or c-side, will be your slant height. take the square of the distance from the circle-base's center to the apex. add that to the square of the radius of the base. Find the square root (using your calculator) of that sum, and there's your answer.
Answer: (a) 4x + 10(0) = 76
(b) 29questions
Step-by-step explanation: let the correct answer = x.
4points for correct answer each total 4xpoints
Since no penalty for wrong answers, his total points were 76points.
Equation: 4x = 76
x = 19. He scored 19 correct answers.
Total number of questions on the test = 19 correct answers + 10 wrong answers
29 questions
4 days because he drinks 6 in two and 12 in 4 days.
