Write 4×10-2 as a decimal.

galina1969 [7]

Answer:

4x10=40-2=38

38% = 0.38 in decimal form. Percent means 'per 100'. So, 38% means 38 per 100 or simply 38/100. If you divide 38 by 100, you'll get 0.38 (a decimal number).

Answer:

<h2>25 square inches </h2>

Step-by-step explanation:

Given, 

Parallel sides of the trapezium = 3in, 7in

Height of the trapezium = 5in

Therefore, 

Area of the trapezium

$= \frac{1}{2} \times sum \: of \: parallel \: sides \times height$

$= \frac{1}{2} \times (7 + 3)in \times 5in$

$= \frac{1}{2} \times 10in \times 5in$

= 5in × 5in

$= {25in}^{2}$

Hence,

Area if the trapezium is 25 square inches (Ans)

Crank

Answer:

b. 2 cans of ink

Step-by-step explanation:

In order to calculate the number of cans you need to paint the complete wall, you first calculate the area of the wall by using the information about its width and height:

$A=(5m)(2,5m)=12.5m^2$

With one can you can paint 10m^2 of wall, with two cans you can paint 20m^2, which is enough to paint the wall of 12.5m^2.

Then, you need only two cans of ink
