When you are rounding to a certain place value, first identify the place value you are rounding to by underlining it. The digit to the immediate right of that number will determine whether you add 1 to the underlined digit or it remains the same.
For example....
1. 7.445 rounded to the nearest tenth. Underline the first 4 after the decimal and circle the 4 that is to the right. Answer this question....is the number that is circled 5 or greater? If the answer is YES, add one to the underlined digit. If the answer is NO, leave the underlined number the same and change all remaining digits to the right of it to ZERO. Most of the time, those ZEROs will simply vanish because they are unnecessary.....
7.445 = 7.4 rounded.
2. 7.999 rounded to the nearest tenth. This one is a bit trickier....but you'll still follow the same process. Underline the first 9 next to the decimal and circle the 9 immediately to the right. The answer to the question is yes, so you'll add one to the underlined digit. This will cause it to become a zero and you'll add 1 to your whole number. BUT....keep that 0 there because it's in the tenths place. All of the other digits will vanish.
7.999 = 8.0 rounded.
Follow that same process for the remainder of your questions and you will have mastered the art of ROUNDING!!!!
Hope that's clear and GOOD LUCK!
Answer:
32.1
Step-by-step explanation:
d=sqrt ((x2-x1)^2+(y2-y1)^2 )
Find length of AB
d=sqrt((2-(-4))^2+(0-5)^2)
d=sqrt(6^2+(-5)^2)
d=sqrt(36+25)
d=sqrt(61)
d= around 7.8
Find length of BC
d=sqrt((4-(-4))^2+(10-5)^2)
d=sqrt(8^2+5^2)
d=sqrt(64+25)
d=sqrt(89)
d= around 9.4
Find length CD
d=sqrt((8-4)^2+(7-10)^2)
d=sqrt(4^2+(-3)^2)
d=sqrt(16+9)
d=sqrt(25)
d=5
Find length DE
d=sqrt((4-8)^2+(5-7)^2)
d=sqrt((-4)^2+(-2)^2)
d=sqrt(16+4)
d=sqrt(20)
d= around 4.5
Find length EA
d=sqrt ((4-2)^2+(5-0)^2 )
d=sqrt(2^2+5^2)
d=sqrt(4+25)
d=sqrt(29)
d= around 5.4
P=7.8+9.4+5+4.5+5.4
P=32.1
X=1
Just pluck in the 1 into x and there’s is the answer
For the left you’re rising 6 & running -2. For the right your rising -6 & running 2.
1. To the question whether it is a good idea to design a drink can from a solid nonmetal, the answer is <u>No, because nonmetals lack luster</u>.
<h3>The Luster in Nonmetal</h3>
Non-metals do not have luster because they cannot reflect light from their surface with their dull appearances. Diamond and iodine are two exceptions to lustrous non-metals.
2. The reason it is not a good idea designing a drink can from a solid nonmetal is <u>No, because nonmetals are brittle.</u> Generally, solid nonmetals are known to be <u>dull and brittle</u>. They can easily break into pieces.
Thus, non-metals are <u>not ductile or malleable</u>.
