b. six equilateral triangles

Step-by-step explanation:

The 6 interior angles of the hexagon are supplementary to the exterior angle and are 120 deg. ... Therefore the angles at the center is 360/6 = 60 degrees for each triangle. So all three angles of the six triangles are 60 deg each. So there are 6 equilateral triangles that form the regular hexagon.

olga_2 [115]

Answer:

The actual salary of usman was Rs. 3461.53

Step-by-step explanation:

Given that:

Percent increase in salary = 30%

Total salary percent would be = (100+30)% = 130%

Salary after increment = Rs. 4500

Let,

x be the actual salary before increase.

According to given statement,

130% of x = 4500

$\frac{130}{100}x=4500\\1.3x=4500$

Dividing both sides by 1.3

$\frac{1.3x}{1.3}=\frac{4500}{1.3}\\x=Rs 3461.53$

Hence,

The actual salary of usman was Rs. 3461.53

A rental car company charges $54.35 per day to rent a car and $0.09 for every mile driven. Jayden wants to rent a car, knowing t

SIZIF [17.4K]

The inequality representing d, the total number of days Jayden can rent the car while staying within his budget is 54.35d + 38.25 ≤ 310

Given:

Charge per day = $54.35

Charge per mile = $0.09

Total miles = 425 miles

Amount to spend = at most $310

let

d = number of days

The inequality:

54.35 × d + 0.09 × 425 ≤ 310

54.35d + 38.25 ≤ 310

54.35d ≤ 310 - 38.25

54.35d ≤ 271.75
