Answer:
3.76 × 10^4
Step-by-step explanation:
<em>1. Work out what they are.</em>
1.26 × 10^4 = 12600 (check your calculator to see if I'm right)
To get this, I multiplied 1.26 by 10,000. This is because 10^4 is 10000 (it has 4 zeros). Or you could move the decimal point forward 4 spaces.
2.50 × 10^4 = 25,000
By doing the same thing above.
<em>2. Add them together</em>
12,600 + 25,000 = 37,600
<em>3. Change the answer into its scientific notation</em>
To do this we need to divide 37,600 by a number to make it less than 10, but still keeping the digits. This always ends in zeros by the way (e.g. 100, 1,000, 100,000).
37600 ÷ 10,000 = 3.76
Next:
Scientific notations always have times 10 to the power of something (× 10^x). So we put that in:
3.76 × 10^x what is x?
x is the number of of times you multiply by 10 to get back to 36700. This is 4 times.
(This is the same as multiplying by 10,000 as it has 4 zeros. This is also the same as moving the decimal point 4 spaces)
So your final answer is: 3.76 × 10^4
Set the equations equal to each other and solve for the variable x. then use the answer from x and plug it in to the equations and you should get an answer
3x=63
63÷3=x
21=x
x=21
that is the value of x
73 is the answer to the top equation and the bottom equation in the triangle. Meaning the equations are equal to each other when you have 21 plugged in for the variable x.
make sure to put your label if it asks for it. it means the book or the teacher. go by what the teacher says if it is different from what the book says
Answer:
Option (4)
Step-by-step explanation:
Definition of a ray states that a segments which connects two points but extending only in one direction infinitely is called as Ray.
Opposite rays will have a common end but the direction of the arrows will be different.
Therefore, from the picture attached,
Opposite rays will be PA and PB.
Option (4) will be the correct option.
The area of the parallelogram is mathematically given as
A = 7 square units Option B
<h3>What is the area of the parallelogram?</h3>
Generally, the equation for a parallelogram is mathematically given as
A=bH
Where
b=4.123
and
H=1.75
Hence
A=3*1.75
A=7.2square units
In conclusion, a parallelogram
A = 7 square units
