Look at the rectangle and the square:
A rectangle PQRS and square LMNO are drawn side by side. The length SR of the rectangle is labeled as 12 inches, and the width QR is labeled as 6 inches. The side LM of the square is labeled as 6 inches
Sam says that the length of diagonal SQ is two times the length of diagonal OM.
Is Sam correct? Justify your answer and show all your work. Your work should state the theorem you used to find the lengths of the diagonals.
Answer:
False
Step-by-step explanation:
Let's consider the triangle SQR. We know it is right-angle because part of the rectangle PQRS. We can use the Pythagorean theorem:
[tex]SQ^{2} = RQ^{2} + SR^{2} \\SQ^{2} = 36 + 144 = 180\\SQ = \sqrt{180} = 13,4[/tex]
We can do the same for the square in which ON = 6 because it's a square:
[tex]OM^{2} = MN^{2} + ON^{2} \\OM^{2} = 36 + 36 = 72\\OM = \sqrt{72} = 8.5[/tex]
Now let's compare them:
8.5 X 2 = 17 so OM X 2 is not equal to SQ
The sentence is false.

Find the value of the following expression 100 - 2(x + 5) when x = 10 *
Answer:
70
Step-by-step explanation:
100 - 2(x + 5) = 100 - 2x - 10 = 90 -2x
90 - 2x
90 - 2×10
90 - 20 = 70

the area of a yard is 192 yd2 what is the perimeter
Answer:
if its a square this is your answer 36864 if its a rectangle this is your answer 384
Step-by-step explanation:
u really didnt give enough info and im not sure if that 2 is a typo but if ur finding the area of a square thats the asnswer
Answer:
the perimeter is 32sqrt(3) yd, or approximately 55.4 yd
Step-by-step explanation:
A square has 4 congruent sides, so if the length of 1 side is s, the perimeter is 4s. Also, the area of a square is the side squared, or A = s^2.
A = s^2
s^2 = 192 yd^2
Take the square root of both sides.
s = sqrt(192)
s = sqrt(64 * 3)
s = 8sqrt(3)
P = 4s
P = 4 * 8sqrt(3) = 32sqrt(3)
Answer: the perimeter is 32sqrt(3) yd, or approximately 55.4 yd

Find the period.
Principal = 9300 rupees
Annual rate of interest = 13%
Total amount = 17,763
Period = _____ years
Answer:
The Time period of the Amount is 5 years 3 days .
Step-by-step explanation:
Given as :
The principal = p = Rs 9300
The annual rate of interest = r = 13%
The Total amount after t years = A = Rs 17,763
Let The time period = t years
From Compound Interest method
Amount = principal ×
Or, A = p ×
Or, Rs 17,763 = Rs 9300 ×
Or, =
or, 1.91 =
Taking Log both side
1.91 = ( )
or, 0.2810 = t × 1.13
or, 0.2810 = t × 0.0530
∴ t -
I.e t = 5.30 years
So, The time period = t = 5 years 3 days
Hence The Time period of the Amount is 5 years 3 days
