Answer:
The first number should be a number between 1 and 10 (see explanation)
Step-by-step explanation:
For a number to be in scientific notation, a number between 1 and 10 has to be multiplied by a power of 10.
36.5 is not between 1 and 10, alternatively, you can rearrange it:
3.65 x 10^7 <----This would be the correct scientific notation
Answer:
<em>D. 30</em>
Step-by-step explanation:
6 ÷ 1/5 <em>-given expression</em>
6 x 5 <em>-use the </em><em>keep, change, flip </em><em>method, where you</em><em> keep</em><em> the </em><u><em>first </em></u><em>number, </em><em>change</em><em> the </em><u><em>division sign</em></u><em> to a </em><u><em>multiplication sign</em></u><em>, and </em><em>flip</em><em> the f</em><u><em>raction</em></u><em> that comes after the symbol.</em>
<em>6 x 5 = 30</em>
<em>30 is the answer</em>
Answer: 1.
Given: S is the midpoint of RT
PR=PT
To Prove: PRS=PTS
Step-by-step explanation:
If PR=PT in a triangle PRT, then the triangle is isosceles triangle.
Therefore, ∠PRT=∠PTR (opposite angles of an isosceles triangle are equal)
In ▲PRS and ▲PTS
PR=PT
∠PRT=∠PTR
PS=PS (PS is common)
therefore, ▲PRS≅▲PTS
Therefore, ∠PRS=∠PTS
Hence proved.
Answer: 2.
Given: E is the midpoint of AB and CD.
To Prove: AEC=BED
Step-by-step explanation:
If AB and CD are the diagonals of rectangle, then
diagonals AB=CD, sides AC=BD and AD=BC
In ▲AEC and ▲BED,
∠AEC=∠BED(vertically opposite angles)
AE=BE
AC=BD
therefore, ▲AEC≅▲BED
Therefore, ∠AEC=∠BED
Hence Proved.
Answer:
21.6 feet
Step-by-step explanation:
Assuming the desk is a rectangular shape, you would find the perimeter of his desk.
x = 2(6.5 + 4.3)
OR
6.5 + 6.5 + 4.3 + 4.3
=21.6
Hope this helped! :)
If the length of the garden is 5 more than twice the width, then length = 2 X width + 5.
P = 70
L= 2W + 5
P = 2 X (L + W)
70 = 2 X ((2W+5) + W))
You can take the + 5 out at this point by multiplying it by the 2 outside the brackets (5 for each length)
70 - (2X5) = 2X ((2W) + W)
70 - 10 = 2 X (2W + W)
60 = 2 (3W)
60 = 2*3W
60 = 6W
10 = W
The width is 10.
So what's the length? 2W + 5
Length = 2 * 10 + 5
Length = 25.
Length is 25, width is 10.
Check: 70 = 2 (25 + 10)
70 = 2(35)
70 = 70
Correct!
