Inequality: 21d+25≤115

Jim can rent a car for maximum 4 days, therefore, he is not correct in his calculations.

Step-by-step explanation:

Given,

Per day rent = $21.00

Per mile rent = $0.10

Miles to be driven by Jim = 250

Cost of 250 miles = 250*0.10 = $25

Amount Jim can spend = $115.00

Let,

d represent the number of days.

Per day rent*number of days + cost of 250 miles ≤ Total amount to spend

21d+25≤115

Subtracting 25 from both sides

$21d+25-25\leq 115-25\\21d\leq 90$

Dividing both sides by 21

$\frac{21d}{21}\leq \frac{90}{21}\\d\leq 4.28$

Jim can rent a car for maximum 4 days, therefore, he is not correct in his calculations.

Explain why any of the four operations (+x +) placed between the two terms 5 and-3/(radical sign) 8 will result in an irrational

kompoz [17]

To answer this question we will have to understand the nature of $\sqrt{8}$ .

$\sqrt{8}$ can be rewritten as: $\sqrt{2\times 2\times 2} =2\sqrt{2}$ . Now, $\sqrt{2}$ is an irrational number and thus any of the four operations of addition, multiplication, subtraction or division placed anywhere between any of these terms will always result in an irrational number.

The only way irrational numbers can be made rational is by dividing or multiplying the given irrational number by the same irrational number.

(1+5/6)(1-5/6)<br><br> I don't understand it

ipn [44]

(a+b)(a-b) = a^2 - b^2

(1+5/6) (1-5/6) = 1^2 - (5/6)^2 = 1 - 25/36 = 36/36 - 25/36 = (36-25)/36 = 11/36

11/36 is your answer
