A tabletop in the shape of a trapezoid has an area of 5,369 square centimeters. Its longer base measures 131 centimeters, and th

Illusion [34]

Answer:

The height of the trapezoid = 45.5 cm

Step-by-step explanation:

Here, the length of the base = 131 cm

The length of the shorter side = 105 cm

Let us assume the height = h

Also, area of the trapezoid = 5,369 sq. cm

Now, AREA OF THE TRAPEZOID = $\frac{1}{2} \times \textrm{(Sum of parallel sides)} \times h$

$\implies 5,369 = \frac{1}{2} \times (131 + 105) \times h\\\implies h = \frac{5,369 \times 2}{236} = 45.5$

or, h = 45.5 cm

Hence the height of the trapezoid = 45.5 cm

Find (2.2 x 107)(5 x 108) (2.5 x 103)(8.8 x 105) expressed in scientific notation.

jarptica [38.1K]

Answer:

Scientific notation of the multiplication is $2.42\times 10^{25}$

Step-by-step explanation:

$(2.2\times 10^{7})(5\times 10^{8})(2.5\times 10^{3})(8.8\times 10^{5} )$

= $(2.2\times 5\times 2.5\times 8.8)10^{(7+8+3+5)}$

[Since $10^{a}\times 10^{b}=10^{(a+b)}$ ]

= $242\times 10^{23}$

= $2.42\times 10^{25}$

Therefore, the scientific notation of the multiplication is $2.42\times 10^{25}$
