(−5.2)+(−3.8)–{(−1.2)–[(−0.5)–(−0.7)]}

To simplify this problem we will use order of operations. PEMDAS which stands for Parenthesis Exponent Multiplication Division Addition Subtraction

=(−5.2)+(−3.8)–{(−1.2)–[(−0.5)+0.7]}

=(−5.2)+(−3.8)–{(−1.2)–[−0.5+0.7]}

=(−5.2)+(−3.8)–{(−1.2)–[0.2]}

=(−5.2)+(−3.8)–{(−1.2)–0.2}

=(−5.2)+(−3.8)–{−1.2–0.2}

=(−5.2)+(−3.8)–{-1.4}

=(−5.2)+(−3.8)+1.4

=(−5.2)−3.8+1.4

=(−5.2)-2.4

=−5.2-2.4

=-7.6


Hence final answer is -7.6.

Micah places a mirror on the ground 24 feet from the base of a tree. He walks
irina [24]

The height of tree is 8 feet

<h3><u>Solution:</u></h3>

Given, Micah places a mirror on the ground 24 feet from the base of a tree

At that point, Micah's eyes are 6 feet above the ground  

And he is 9 feet from the image in the mirror.  

To find : height of tree = ?

Let "n" be the height of tree

From the question, we can see there is a directly proportional relationship between heights and distances.

Proportional relationships are relationships between two variables where their ratios are equivalent.

\frac{\text { height of micah eyes above ground }}{\text { distance of micah from mirror }}=\frac{\text { height of tree above the ground }}{\text { distance of tree from mirror }}

\begin{array}{l}{\frac{6 \text { feet }}{9 \text { feet }}=\frac{n \text { feet }}{24 \text { feet }}} \\\\ {\frac{6}{9}=\frac{n}{24}} \\\\ {\text { n }=\frac{1}{3} \times 24} \\\\ {\text { n }=8}\end{array}

Hence, the height of the tree is 8 feet

What is, 7 3/10+6 1/3+2 7/10?
snow_lady [41]

7 3/10 + 6 1/3 + 2 7/10

First change them to improper fractions

73/10 + 19/3 + 27/10

now find the common denominator which would be 30

73/10 = 219 /30

19/3 =   190/30

27/10 =  81 /30

now add (219 + 190 + 81) = 490/30

now divide 490 ÷ 30 = 16 1/3

Your answer is 16 1/3

Hope this helps. :)
