The gcf of 170 and 210 is 10.
The simplified mathematical expressions with the first factor to the nearest tenth are:
7.8 x 10
3.3 x
2.1 x
3.7
<h3>What are the
simplified mathematical expressions ?</h3>
Scientific notation is used to simplify large numbers in smaller numbers. In order to write a number in scientific notation , the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.
(8.6 x ) . (9.1 x )
= (8.6 x 9.1) x
= 78.26 x
= 7.8 x 10
(6.9 x ) . (4.8 x )
= 33.12 x
3.3 x
(3.7 x ) . (4.6 x ) ÷ (1.4 x ) . (5.7 x )
= 1.7 x 10 ÷ 8 x10²
0.21 x
2.1 x
(3.1 x ) . (5.3 x ) ÷ (7.3 x ) . (6.1 x ) = 3.7

The scale factor 0.05 refers to length, so for area the scale factor is 0.05²=0.0025.
We then multiply: 220 ft²*0.0025=0.55 ft² (choice A)
Answer:
162°
Step-by-step explanation:
a circle has 360°, or the angle of a whole circle is that
so 45% of 360 =
0.45 times 360 = 162
Answer:
It can hold up to of waste
<em></em>
Step-by-step explanation:
Given
-- Diameter
-- height
Required
Determine the amount of waste it can hold
This simply means that we calculate the volume of the cylindrical container.
And this is calculated using:
Where
and
So, we have:
<em>Hence, it can hold up to </em><em> of waste</em>
