Answer:
4. 110 slices
5. B.12.8 mi
Step-by-step explanation:
For question for you divide the number of slices, 176, by the number of loafs, 8. this give give you a total of 22. you then take 22 and multiple if by 5, leaving your answer to 110 slices of bread.
For question 5, you multiple 8 kilometers by 1.6 kilometers, which is 12.8 miles.
I hope this helps :))
Answer:
282 hr <======= see below
Step-by-step explanation:
Distance / rate = time
2.4 x 10^9 mi / 85 m/hr = 28235294 hr
You must have left the power of 10 off of your speed
probably should be 8.5 x 10^6 perhaps? then answer is 282
<h3>If speed was 8.5 x 10^5
then answer becomes ~ 2820 </h3>
Answer:
B. The length of the hallway; D. The weight of the wombat
Step-by-step explanation:
A variable is an <em>unknown</em><em> </em><em>value</em><em> </em>in an equation.
Twelve ounces of tea is a <em>known</em><em> </em><em>value</em>
Seven cups of flour is a <em>known</em><em> </em><em>value</em>
<h3>
<em>The</em><em> </em><em>length</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>hallway</em><em> </em><em>is</em><em> </em><em>unknown</em><em> </em></h3><h3>
<em>The</em><em> </em><em>weight</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>wombat</em><em> </em><em>is</em><em> </em><em>unknown</em><em> </em></h3>
<em>Therefore</em><em> </em><em>B</em><em> </em><em>and</em><em> </em><em>D</em><em> </em><em>are</em><em> </em><em>the</em><em> </em><em>right</em><em> </em><em>answers</em><em> </em><em>;</em><em>)</em><em> </em>
For both of these questions, we have to use PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. This is the order that we need to do things.
1.)
(1 x 2) x 3^2 x 4 + 5
Parentheses - multiplication
2 x 3^2 x 4 + 5
Exponents
2 x 9 x 4 + 5
Multiplication
72 + 5
Addition
<u>77</u>
2.)
8 + 6 x 3 x 4 x 8
Multiplication
8 + 576
Addition
<u>584</u>
