Answer: Assuming the unit is dollars, the answer would be $5,010.
Explanation:
Step 1: 8000-300 is 7700.
Step 2: 7700-290 is 7410
Step 3: 7410-400 is 7010
Step 4: 7010-2000 is 5010
So, the answer is Anna has $5,010 dollars left after giving Jim $300, buying shoes for $290, a suit for $400 and spending $2,000 dollars on a new phone.
The common ratio of the GP is 3/2.
Step-by-step explanation:
- Step 1: Find first and second terms to find the common ratio, r = a(2)/a(1)
⇒ a(1) = 3^1-1/2^1 = 3^0/2 = 1/2
⇒ a(2) = 3^2-1/2^2 = 3^1/4 = 3/4
- Step 2: Find the common ratio
⇒ r = a(2)/a(1) = 3/4 ÷ 1/2 = 3/4 × 2/1 = 3/2
Answer: Step function (or staircase function)
This is because the graph resembles steps or a staircase.
Each step is a horizontal line as described by the pricing chart.
- From x = 0 to x = 25, we'll have a horizontal line y = 3.50
- From x = 25.01 to x = 75, we have a horizontal line y = 5.95
- From x = 75.01 to x = 125, we have a horizontal line y = 7.95
- From x = 125.01 and onward, we have a horizontal line y = 9.95
The diagram below shows this. Note how the horizontal lines are separate pieces that are not connected by vertical lines. Vertical lines are not allowed in functions.
Answer:

Step-by-step explanation:
Given expression

To solve for
for the given expression.
Solution:
We multiply each term with the least common multiple of the denominators of the fraction in order to remove fractions.
The multiples of the denominators are:
3 = 3,6,9,<u>12</u>,15
6 = 6,<u>12</u>
4 = 4,8,<u>12</u>
The least common multiple = 12.
Multiplying each term with 12.


Using distribution.

Simplifying.

Adding
both sides.


Adding 51 both sides.


Dividing both sides by 15.


Simplifying fractions.

∴
