Answer:
2 $
Step-by-step explanation:
let the original price be x
price after 10% discount = 3.60$
The original price of 2 pens is 4$
original price of one pen = 4/ 2
<u>= 2 $</u>
Answer:
5 d) 9 1/3
6 d) 2
Step-by-step explanation:
Proportions:
5
7 ⇒ 4
BY ⇒3
BY = 7*4/3
BY = 28/3
28/3 = 27/3 + 1/3 = 9 1/3
BY = 9 1/3
6
12 ⇒ 3
8 ⇒ SX
SX = 3*8/12
SX = 2
Answer:
Step-by-step explanation:
Please use " ^ " to denote exponentiation: f(x) = x^2 + 4x - 21.
This function has a graph which is a parabola that opens up.
Its vertex is found by completing the square:
x² + 4x + 4 - 4 - 21, or
(x + 2)² - 25
Comparing this to the standard equation
(x - h)² + k, we see that h = -2 and k = -25.
Thus, the vertex (and the minimum of this function) is (-2, -25).
Thus, the range is [-25, ∞ ). This being a polynomial function, it has no restrictions on the domain: the domain is (-∞, ∞ )
Answer:
The circle's area is 380.13 square miles.
Step-by-step explanation:
A = pie * r^2 = pie * 11^2 = 380.13
I hope this somewhat helped you find your answer.
(a) The equation for estimating the weight W of the Golden Delicious apples is W + 20 = 44.
(b) The weight of the Golden Delicious apples is 24 pounds.
- <em>Let the weight of the Golden Delicious apples = W</em>
- <em>Weight of the Honeycrisp apples = 20 lb</em>
- <em>Total weight of the apples = 44 lb</em>
The equation for estimating the weight W of the Golden Delicious apples is calculated as follows;
<em>Weight of Golden delicous apples </em><em>+ </em><em>Weight of Honeycrisp </em><em>= </em><em>Total weight of the apples</em>
W + 20 = 44
The weight of the Golden Delicious apples is calculated as follows;
W + 20 = 44
<em>collect similar terms together;</em>
W = 44 - 20
W = 24 lb
