Answer: 1. d.
2. a. (5, 28)
3. a: C(n) = 0.90 n - 0.40
Step-by-step explanation:
1. Here x represents the saving of one day.
Thus, the total saving for 7 day = 7 x
And, my goal is to save at least $350.00 ( According to the question)
⇒
⇒ ( by dividing both sides by 7 )
Therefore, Option d is correct.
2. since, if a point satisfies an equation then we can say that it is the solution of the equation.
(5,28) satisfies y= 5x + 3
Because at x = 5, 5×5 + 3 = 25 + 3 = 28
except this point other points (28, 5), (4, 20) and (3, 19) are not satisfying given equation of line.
Therefore, only (5,28) is the solution of line.
⇒ Option a is correct.
3. Here n represents the number of tunas.
And, according to question the cost of one tuna = $0.90
⇒ Cost of n tunas = $ 0.90n
But again according to the question,
I have a coupon for $0.40 off your total purchase.
Thus, $ 0.40 will be less from my total purchasing cost.
⇒ The cost of n tunas = $ (0.90 n - 0.4)
Option a is correct.
Answer:
Yes, The pole will fit through the door because the diagonal width of the door is 10.8 feet, which is longer than the length of the pole.
Step-by-step explanation:
Using the Pythagorean Theorem, ( ) we can measure the hypotenuse of a right triangle. Since the doorway is a rectangle, and a rectangle cut diagonally is a right triangle, we can use Pythagorean Theorem to measure the diagonal width of the doorway.
Plug in the values of the length and width of the door for a and b. The c value will represent the diagonal width of the doorway:
Since 117 is equal to the value of c multiplied by c, we must find the square root of 117 to find the value of c.
Yes, The pole will fit through the door because the diagonal width of the door is 10.8 feet, which is longer than the length of the pole, measuring 10 feet.
