If t is a number between 6 and 9, t+5 is between what two numbers?
Answer:
11 and 14
Step-by-step explanation:
t can be 7 or 8
7+5=12
8+5=13
12 and 13 are between 11 and 14
The number t + 5 is in between 11 and 14.
What is an inequality?"It is a mathematical statement of an order relationship (greater than, greater than or equal to, less than, or less than or equal to) between two numbers or mathematical expressions."
What is addition property of inequality?" Let x, y, and z be real numbers.
If x > y, then x + z > y + z."
For given question,
t is a number between 6 and 9.
So, we have an inequality.
⇒ 6 < t < 9
By addition property of inequality,
⇒ 6 + 5 < t + 5 < 9 + 5
⇒ 11 < t + 5 < 14
Therefore, the number t + 5 is in between 11 and 14.

what is the volume of the rectangular prism
It is all the numbers multiplied together. 135
Answer:
[tex]\Huge\boxed{D.135 cm^3}[/tex]
Step-by-step explanation:
Hello There!
We can find the volume of the figure by using the formula for volume of a rectangular prism
[tex]V=lwh[/tex]
where l = length, w = width and h = height
we are given all of the dimensions so all we have to do is plug in the values
so
V = 3 x 9 x 5
3x9=27
27x5=135
so the volume of the rectangular prism is 135 cm³

What is fraction?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
Given:
It takes an old printer 8 hours to print all the pictures for the yearbook.
A modern printer can do the same job in 5 hours.
If both work together,
it will take,
x(1/8 + 1/5) = 1
x(8 + 5)/40 = 1
8x + 5x = 40
x = 40/13
x = 3.07
x = approximately 3.1 hours.
Therefore, the work will be done in 40/13 hours.

The length of the diagonal drawn by Leah will be 50 feets
Given the Parameters :
Length = 48 feet Width = 14 feetsThe length of the diagonal is the value of the hypotenus in a right angles triangle :
Let the length of the diagonal = d
d = √(length)² + (width)²
d = √48² + 16²
d = √2304 + 256
d = √2560
d = 50.5961 feets

Comment on units
The problem statement tells us "each unit of coordinate plane represents one acre." An acre is a unit of area, so we have to assume this means that each square unit represents one acre. That means each unit on each axis is about 208.71 feet, the dimension that would have to be squared to get an area of one acre--43,560 square feet.
