The length of a rectangle is 2 ft shorter than 5 times its width, x. The area of the rectangle is less than 100 f12.

Ierofanga [76]

Answer:

Step-by-step explanation:

Area of rectangle = length x width

length = 5x - 2

width = x

area = (5x - 2) × x

100 = 5x² - 2x

the width would be less than the area of the rectangle, thus the inequality sign to be used is <

5x² - 2x < 100

6) A demand curve for a product is the number of items the consumer will buy at different prices. At a price of $2 a store can s

ExtremeBDS [4]

Given :

When price is $2 dollars he sells 2400 units .

When price is $8 dollars he sells 600 units .

To Find :

If x represents the price of trucks and y the number of items sold, write an equation for the demand curve.

Solution :

Two points are given :

$(x_1,y_1)=(2,2400)$

$(x_2,y_2)=(8,600)$

Now , slope is given by :

$m=\dfrac{y_2-y_1}{x_2-x_1}\\\\m=\dfrac{2400-600}{2-8}\\\\m=\dfrac{-1800}{6}\\\\m=-300$

Now , the equation of line containing these two points and slope -300 is :

$(y-y_1)=m(x-x_1)\\\\y-600=-300(x-8)\\\\y=-300x+2400+600\\\\y=-300x+3000$

Therefore , equation for the demand curve is $y = -300x +3000$ .

Hence , this is the required solution .

Mr. Ramirez gave his class

Angelina_Jolie [31]

Answer:

38 pages per hour

Step-by-step explanation:

Rate of reading = $\frac{\text{Total number of pages read by Davida}}{\text{Time taken to read}}$

By substituting the given values in the question,

Total number of pages read by Davida = $28\frac{1}{2}$ = $\frac{57}{2}$

Time taken by Davida = 45 minutes

Since, 1 minute = $\frac{1}{60}$ hours

Therefore, 45 minutes = $\frac{45}{60}=\frac{3}{4}$ hours

Rate of reading = $\frac{\frac{57}{2}}{\frac{3}{4} }$

= $\frac{57}{2}\times \frac{4}{3}$

= 38 pages per hour

Therefore, rate of reading by Davida is 38 pages per hour.

tyler read 15 pages of a book. Ann read 9 pages of the same book. Did Tyler read 4 more pages than Ann? Explain

Slav-nsk [51]

No because fifteen minus nine is six, so Tyler read six more pages than Ann.
