s = ½ (u + v) * t and we are told
u = 18 v = 14 and t = 100 so, we put those into the formula:
s = ½ (18 + 14) * 100
s = ½ (32) * 100
s = ½ * 3,200
s = 1,600

The base of a cube is parallel to the horizon. If the cube is cut by a plane to form a cross section, under what circumstance would it be possible for the cross section be a non-rectangular parallelogram?
Answers
The cross-section of a cube can be a non-rectangular parallelogram when the cutting plane is not perpendicular to the cube's base.
The scenario where a cube's cross-section can be a non-rectangular parallelogram occurs when the cutting plane is at an angle other than a right angle to the cube's base. This results in a parallelogram that is not a rectangle, as the cutting plane affects the shape of the cross-section.
When the cutting plane deviates from being perpendicular to the base of the cube, it creates a cross-section that is not a rectangle but can be a parallelogram with unequal angles and sides.
Understanding the geometric implications of the cutting plane's orientation is crucial in visualizing how the cube's cross-section can vary from a rectangular shape to a non-rectangular parallelogram.
Sandy had 161 dollars to spend on 9 books. After buying them she had 17 dollars. How much did each book cost
Answers
If their food and beverages cost $25.30 and there is an 8% meals tax
Answers
Tax = 8% x $23.50
= $18.80
End cost = $25.30 + $18.30
= $44.10
Hope this helps :))
~Top
Answer:
Then they'll pay $27.32
Step-by-step explanation:
In order to determine this, start by multiplying the cost of the meal by the tax amount.
25.30 * 8% = 2.02
Now add the tax to the meal cost
25.30 + 2.02 = 27.32

Which is correct regarding the statement: “If x is an odd integer, then the median of x, x + 2, x + 6, and x + 10 is an odd number”
Answers
the median is the number in the middle when the numbers are arranged in increasing order
if there are an even number of numbers in the set, take the average of the middle 2
we have x,x+2,x+6,x+10
there are 4 numbers, so the median will be the avergage between x+2 and x+6 which is [tex]\frac{x+2+x+6}{2}=\frac{2x+8}{2}=x+4[/tex]
now, if x is odd, then replace x with 2n+1
(2n+1)+4=
2n+1+4=
2n+5=
2n+2(1)+1
even+even+odd=odd
the statement is true
x+2 is also odd (eg: x = 3, so x+2 = 3+2 = 5)
x+6 is also odd for similar reasons above
x+10 is also odd
We have four values. The median is found in the middle, so exactly halfway between x+2 and x+6
Add up x+2 and x+6 to get
(x+2)+(x+6) = 2x+8
Then divide that result by 2. In other words, divide everything by 2
2x/2+8/2 = x+4
The result x+4 is odd since adding any even number to an odd number is going to result in an odd value
So the claim is true
--------------------------------------------------------------------------------
Alternative method:
x is odd so x = 2k+1 where k is any integer
x+2 = 2k+1+2 = 2k+3
x+6 = 2k+1+6 = 2k+7
x+10 = 2k+1+10 = 2k+11
Add up the two middle terms
(x+2)+(x+6) = (2k+3)+(2k+7) = 4k+10
Divide that result in half
4k+10 ---> 4k/2 + 10/2 = 2k+5 = 2k+4+1 = 2(k+2)+1
The expression 2(k+2)+1 fits the form 2m+1 where m = k+2 is an integer
So 2(k+2)+1 is odd making the median to be odd.
This further helps support why the claim is true

Answers
Unit conversion is the conversion of one unit to another unit with its standard conversion.
The actual dimension of the recreation room is 24 feet x 21 feet.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Example:
1 minute = 60 seconds
1 km = 1000 m
1m = 100 cm
1 hour - 60 minutes
We have,
Recreation room dimension on the blueprint:
= 2 inches x 1.75 inches ______(A)
Scale factor:
1 inch = 12 feet
The actual dimension of the recreational room:
1 inch = 12 feet
Multiply 2 on both sides.
2 inches = 24 feet _____(1)
1 inch = 12 feet
Multiply 1.75 on both sides.
1.75 inches = 1.75 x 12 feet
1.75 inches = 21 feet ______(2)
From (1) and (2) and (A) we get,
= 2 inches x 1.75 inches
= 24 feet x 21 feet
Thus,
The actual dimension of the recreation room is 24 feet x 21 feet.

What is the simplified form of the following expression square root 1/121
A 2/121
B 1/242
C 11
D 1/11
Answers
Since a square root is like the opposite of multiplying, you can think of the top and the bottom separately for this too!
First, let's start with the top. The square root of 1 is 1, so the numerator is 1.
Now, let's do the bottom. The square root of 121 is 11, so the denominator is 11.
So, the answer is D, 1/11. You can check your answer by squaring it, and getting 1/121.

___________________

Next, we divide the first term of 2x-1 by the first term of 4x^4-10x³+14x²+7x-19 to get 4x^4/2x=2x³ (since 4/2=2 and to divide exponents you subtract the denominator from the numerator).

You can use a minus sign to make a negative number like -2. what happens if you put a plus sign before a number? what about 2++2?
Answers
Final answer:
A plus sign before a number does not change its value. In the expression 2++2, the two plus signs next to each other are interpreted as a positive number followed by another positive number.
Explanation:
When you put a plus sign before a number, it doesn't change the value of the number.
The plus sign is just a symbol to indicate that the number is positive.
In the expression 2++2, the two plus signs next to each other are not a valid mathematical operation.
Instead, it is interpreted as a positive number followed by another positive number.
So, 2++2 is equal to 2+2, which is 4.
