Answer:
Yes
Step-by-step explanation:
Yes. Explanations vary. Sample explanation: The weight itself doubles, so
any measurement of the weight using the same units will also double. We
can also see that by saying if the weight is x pounds, then double that weight
would be 2x pounds. The weight in kilograms will be x ÷ 2.2, and the double
weight will be or (2x) ÷ 2.2 2(x ÷ 2.2), which is also double.
First, i would look at the word sum. what does it mean by sum? the sum of two numbers is what? I think of it as sum=its an addition problem and the sum is what those two numbers added together equal. For example the sum of one and two is thee.
Lets say Matt's number is x.
So we got three numbers here; x, 7.5 and 38.2.
how about i simplyfy; "the sum of his number and 7.5 is 38.2"
What it is saying is that...
x and 7.5's sum is 38.2
if sum means it is an addition problem and 38.2 is the answer to this addition problem between 7.5 and x, even though you want to find x... then if you know this, your neext step is to translate this into an equation.
x plus 7.5 equals 38.2
x+7.5=38.2.
when it is an equation, you must subtract 7.5 by both sides. so it would be x=38.2-7.5
38.2-7.5 is... 30.7
that means x, Matt's number, is 30.7.
to do some these kinds of problems, you have to translate the sentences into an equation.
when it says the word product it is a multiplication problem
when a number is decreased, it is less than the original amount. so you are subtracting from the original number. so it would be "the number minus lets say 2 is equal to lets say four." that would mean the number is 6. x-2=4 is the equation.
I hope this helped out... I don't have the time to explain everything... this info may help...
Answer:
11.31
Step-by-step explanation:
<h3>given:</h3>
The diameter of the circle is 3.6 units.
<h3>to find:</h3>
Value of "a"
<h3>steps</h3>
Circumference of a circle in terms of radius:
Circumference = 2 · π · r = 2 · 3.14 · 1.8 = 11.31 (*)
In terms of diameter:
Circumference = π · d = 3.14 · 3.6 = 11.3 (*)
In terms of area:
Circumference C = √4·π·A = √4·π·10.18 = 11.31 (*)
Lw=A
2l+2w=112
l=6w
2(6w)+2w=112
12w+2w=112
14w=112
w=8
l=48
A=384 ft^2
10*6=60 un the way it is easy
