Answer:
80:280
Step-by-step explanation:
To share £360 in the ratio 2:7, you first find the value of one part by dividing £360 by the total number of ratio parts (9). Then, multiply each part of the ratio by this amount, resulting in £80 and £280.
To share £360 in the ratio 2:7, you first need to understand that the sum of the parts of the ratio (2+7) equals to 9 parts. The amount of £360 should be distributed into these 9 parts.
First, you divide the total amount by the total number of parts:
£360 / 9 = £40.
This result £40 is the value of 1 part. To find the amounts for the ratio 2:7, you multiply each part of the ratio by the value of 1 part:

O A. n1/r = a
✓ B. = a
c. a1/nur
O D. a' = n.
Answer:
B. a = rⁿ
C. a¹/ⁿ = r
Step-by-step explanation:
ⁿ√a = r
The above expression can be simplified as follow:
1. ⁿ√a = r
Recall:
ⁿ√a = a¹/ⁿ
Therefore,
a¹/ⁿ = r
2. ⁿ√a = r
Take the n square of both side
(ⁿ√a)ⁿ = rⁿ
(a¹/ⁿ)ⁿ = rⁿ
a = rⁿ
Answer: the selling price of the television at store B is $1360
Step-by-step explanation:
Assuming the selling price of the television at store B is represented by $B. Store A is selling the television for $800, which is $120 more than half the cost of the television at store B. The equation representing this situation is expressed as
800 = B/2 + 120
Multiplying the left hand side and the right hand side of the equation by 2, it becomes
1600 = B + 240
B = 1600 - 240
B = $1360

What is the slope of the line?
What is the y-intercept?
Answer:
the slope of the line is , and the y-intercept occurs at y = -6 (0, -6) on the plane
Step-by-step explanation:
In order to find the slope and y-intercept, we need to solve for y in the equation, and look at the coefficient accompanying the term in "x" (the slope), and at the pure numerical term (y-intercept):
Therefore the slope of the line is , and the y-intercept occurs at y = -6 (0, -6) on the plane
