4 + 5 log5 x = 38
5log5 x = 38/4 = 9.5
log5 x = 9.5/5 = 1.9
x = 5^1.9
x = 21.28 to nearest hundredth

Use scientific notation to find 508,000,000,000 x 0.0000073. Write the answer in scientific and in standard form.

Answer:

3.7084 x 10^6 (scientific form)

3,708,400 (standard form)

Step-by-step explanation:

Expressing these numbers in scientific notation:

508,000,000,000 = 5.08 x 10^11

0.0000073 = 7.3 x 10^-6

Hence,

508,000,000,00 x 0.0000073

= (5.08 x 10^11) x (7.3 x 10^-6)

= 5.08 x 7.3 x 10^11 x 10^-6

= 37.084 x 10^ [11 + (-6)]

= 37.084 x 10^5

= 3.7084 x 10 x 10^5

= 3.7084 x 10^6 (scientific form)

= 3,708,400 (standard form)

Answer:

Step-by-step explanation:

Area of a triangle:

$A=\frac{b*h}{2}$

In our case:

b=4

h=2

Plug in what we know:

$A=\frac{(4)(2)}{2} \\A=4units$

Find the matching solution:

A.) it is 1/2 the area of a rectangle of length 4 units and width 2 units

X B.) it is twice the area of a rectangle of length 4 units and width two units

X C.) it is 1/2 the area of a square of side length 4 units

X D.) it is twice the area of a square of side length 4 units
