A rectangular prism is 3 ft long 4 ft wide and 2 ft tall. What is the length of the longest diagonal?
Answer: Pythagorean Theorem in 3 D
sqrt ( 3^2 + 4^2 + 2^2) =
sqrt ( 9 + 16 + 4) =
sqrt( 29) = 5.3852 approximately
Step-by-step explanation:
The longest diagonal is about 8.9 inches. The longest length is going to be between the two longest lengths, the width and the height. The Pythagorean theorem is a^2 + b^2 = c^2. Plug the width and height into a and b of the Pythagorean equation. (4)^2 + (8)^2 = c^2. Now simplify the equation. 16 + 64 = c^2. 80 = c^2. Now find the square root of each side. (sqrt)80 = (sqrt)c^2. If you simplify this, you will find that c is equal to about 8.9 inches.
Solve the quadratic equation. Simplify if possible:
-5 (x + 3) 2 = -80
Answer:
Step-by-step explanation:
(x +y)² = x² + 2xy +y²
-5(x + 3)² = -80
-5(x² + 2*x*3 + 3²) = -80
-5(x² + 6x + 9) = -80
Divide the equation by (-5)
x² + 6x +9 = -80/-5
x² + 6x + 9 = 16
x² + 6x + 9 - 16 = 0
x² + 6x - 7 = 0
x² - x + 7x - 7 = 0
x(x - 1) + 7(x - 1) = 0
(x - 1)(x + 7) = 0
x -1 = 0 ; x + 7 = 0
x = 1 ; x = -7

Erwin Elementary decided to plant a garden. They set up a rectangle that was
20.75 meters by 15.8 meters. What is the perimeter of the garden? *
Answer:
P = 73.1 m
Step-by-step explanation:
The length of a rectangle, l = 20.75 m
The width of a rectangle, b = 15.8 m
We need to find the perimeter of the garden. The formula for the perimeter of a rectangle is given by :
P = 2(l+b)
Substitue all the values,
P = 2(20.75+15.8)
P = 2(36.55)
P = 73.1 m
So, the perimeter of the garden is 73.1 m.

51668 to the nearest hundred
Answer:
51700
Step-by-step explanation:
So basically you take the last three numbers. the middle 6 is over 5 so you round the first 6 to 7 and the rule for that is 5 or above round up 4 or below round down
51668 to the nearest hundred is 51700
How to round number to nearest hundred ?
1. Identify the hundreds digit of the number.
2. Identify the next smallest place value.
3. We have to find out,is that digit greater than or equal to five!
4. Increase the hundred digit by 1 if greater or equal to 5 & decrease if less than 5. And every digit after it, becomes zero.
What is the required number ?Given number is 51668
Hundreds digit number is 6.
Next smallest place value is 6, which is greater than 5.
So, After increasing hundred digit by 1,The required number is 51700

Silvia was growing some plants. She measured the height, in inches, of the plants and made this line plot to show her data.
Answer:
5
Step-by-step explanation:
Add all the fractions greater than 1/4 inches
The number of times of Silvia plants should have the height that should be more than 1 by 4 is 6.
Calculation of the number of times;Since the equivalent to 1 by 4 should be like 2/8, 3/12, 4/16 etc. Here the fractions that come after 1 by 4 so it should be more than 1 by 4. So now we have to determine the count and also the x in the column for the measurements so based on this, we can get 6.
Therefore, The number of times of Silvia plants should have the height that should be more than 1 by 4 is 6.

to solve this, you have to multiply both sides by 2 to cancel out the two on the left. you’ll be left with -7w = 84. then, you divide both sides by -7 to isolate the variable, which is w. you’ll end up with w=12.
