Which of the following options have the same value as 2%, percent of 90?

Liula [17]

Answer:

B) $0.02\times 90$

E) $\frac{2}{100} \times 90$

Step-by-step explanation:

Given expression:

2% of 90

Evaluating the expression:

$\frac{2}{100} \times 90$

⇒ $0.02\times 90$

⇒ $1.8$

Evaluating each choices given to check if the value matches with the value of given expression.

A) $0.2\times90$

⇒ $18$

B) $0.02\times 90$

⇒ $1.8$

C) $200\times 90$

⇒ $18000$

D) $2\times 90$

⇒ 180

E) $\frac{2}{100} \times 90$

⇒ $0.02\times 90$

⇒ $1.8$

∴ We see that the value of expressions in options B and E matches with the value of the given expression i.e. 1.8

jason rod his bike 26 miles at a constant speed foe 2 hours. how long will it take him to ride 104 miles at the same speed

mr Goodwill [35]

Find how many miles he rode for 1 hour, by dividing the distance he rode by the time he rode:

26 miles / 2 hours = 13 miles per hour.

Now divide the distance you want to find the time for by his rate:

104 miles / 13 miles per hour = 8 hours.

If a rectangle has an area of 2x^2+7x+3 find the perimeter

nikdorinn [45]

Perimeter of a rectangle = 6x + 8

Solution:

Given area of a rectangle = $2x^2+7x+3$

Let us first factor the given polynomial.

$2x^2+7x+3=2x^2+x+6x+3$

$=(2x^2+x)+(6x+3)$

Taking out common terms in the above expression

$=x(2x+1)+3(2x+1)$

Taking out common term $2x+1$ in the above expression

$=(2x+1)(x+3)$

$2x^2+7x+3=(2x+1)(x+3)$

Area of a rectangle = l × b

Therefore, $l=2x+1$ and $b=x+3$

Perimeter of a rectangle = 2(l + b)

$=2[(2x+1)+(x+3)]$

$=2(2x+1+x+3)$

$=2(3x+4)$

$=6x+8$

The answer is same if you take l = x + 3 and b = 2x + 1.

Hence, perimeter of a rectangle = 6x + 8.
