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

andre [41]

<h2>Answer:</h2>

The score range for the smallest percent of students is:

400 to 700

<h2>Step-by-step explanation:</h2>

From the pie chart or circle graph that is provided to us the smallest percent of the students are 10%

( Since 10% is smallest among 14%,42%,34% and 10%)

and we may observe that the smallest region is denoted or represented by the dark blue region and the range of the score of blue region that is given to us is:

400 to 700

Hence, the answer is:

400 to 700

the diameter of a cylinder is 14cm.the height of the cylinder is 9cm. calculate the Volume and curved surface area

kicyunya [14]

Answer:

The volume is 1386 cm³ and curved surface area is 396 cm².

Step-by-step explanation:

Given that,

The diameter of a cylinder is 14 cm

Height of the cylinder is 9 cm

We need to find the volume and curved surface area .

If r is the radius, r = 14/2 = 7 cm

Volume of a cylinder is given by :

$V=\pi r^2 h\\\\V=\dfrac{22}{7}\times (7)^2 \times 9\\\\V=1386\ \text{cm}^3$

The curved surface area of the cylinder is given by :

$A=2\pi r h\\\\A=2\times \dfrac{22}{7}\times 7\times 9\\\\A=396\ \text{cm}^2$

So, the volume is 1386 cm³ and curved surface area is 396 cm².
