Find the diagonal of a square with a perimeter of 28 inches

Answers

Answer 1

Answer: Perimeter of a square = 4 x the length of one side = 28 in.
Length of one side = 7 in.
Length of the diagonal = square root of (7² + 7²) = 7√2 = 9.899 in (rounded)

Answer 2

Answer: $a-side\ of\ square\n\nperimeter\ is\ 28in\n\n4a=28\ \ \ \ /:4\na=7\ (in)\n\nThe\ diagonal\ (d)\ equal\ a\sqrt2\n\nd=7\sqrt2\ inches.$

Imagine slicing a triangular prism, perpendicular to the two bases.
You would basically just be lopping off some congruent triangle from each base.
The now-exposed inside of the prism would be a rectangle.

What is the excluded value?a/b-2

1. a=0
2. b=2
3. b=-2
4. none of the above

Answers

Answer: The correct option is (2) $b=2.$

Step-by-step explanation: We are given to find the exclude value for the following algebraic expression:

$E=(a)/(b-2)~~~~~~~~~~~~~~~~~~~~~~(i)$

We know that

for a rational expression, we must exclude those values for which the denominator of the fraction becomes zero.

So, in equation (i), the excluded value will be given by

$b-2=0\n\n\Rightarrow b=2.$

Thus, the required excluded value is $b=2.$

Option (2) is CORRECT.

b - 2 = 0 since you cannot divide by 0
b = 2 solve for b. this is where the function is undefined

between 6am and 10am re temperature rose by 5 fahrenheit between 10am and 2pm the temperature rose by 6 fahrenheit between 2pm and 6pm the temperature rose by 0 celsius would you be able to tell how much the temperature rise since 6am why or why not

Answers

Yes, we can able to know the temperature difference from 6 AM to 6 PM.
We need to convert all the temperature into one unit.

6 AM - 10 AM ---> 5 F = -15 C
10 AM - 2 PM ---> 6 F = -14.44 C
2 PM - 6 PM ---> 0 C.

So the total increase is 15C

125apples were shared between jerry and kay. kay received 20% less than jerry.

Answers

if that is the case, then Jerry got 60% and Kay received 40%, because together they make the 100%, or in equations:
kay + jerry = 100%
kay = jerry - 20%
substitute:
jerry - 20% + jerry = 100%
2*jerry = 120%
jerry = 60%
kay = jerry - 20% = 60% - 20%
kay = 40%
if you want to know the amount of apples each has:
kay = 40%(125) = 0.4(125)
jerry = 60%(125) = 0.6(125)
