Write 30/8 as a simplified mixed number.
plz hury plz plz plz
Answer:
3 3/4
Explanation:
30/8 is 3.75 which is equal to 3 3/4
or you can see that 8 goes into 30 completely 3 times and then you have 6/8 left over, which simplifies down to 3/4 because 6/2= 3 and 8/2= 4
Paula walked ¾ mile in 10 minutes. Hannah walked ⅘ mile in 15 minutes. What was the difference in their speeds, in miles per hour?
Answer:
1 3/10 (SORRY IF ThIS IS WRONG)
Step-by-step explanation:
3/4 mile x 6 = 4 1/2
(we multiply by 6 because to get 60 minutes/1 hour you need to multiply 10 minutes by 6)
60/15=4
(we will multiply by 4 because we need that to get 1 hour)
4/5 x 4 = 3 1/5
4 1/2 - 3 1/5 = 4 5/10 - 3 2/10 (we do that so we can subtract easier)
4 5/10 - 3 2/10 = 1 3/10
Kyle held a balloon 8 feet off the ground, straight above his head. Ava is standing 15 feet directly to the right of Kyle.Which equation can be used to find the value of x?
Answer:
Step-by-step explanation:
to get from (1, 7) to (2, 5) you move down two and to the right one
so from (2, 5) go down two and to the right one and you are at (3, 3)
The value of x is 17 unit.
What is Pythagoras theorem?The Pythagorean theorem, or Pythagorean theorem, illustrates the relationship between the three sides of a right-angled triangle. The square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle, according to the Pythagorean theorem.
We know,
Kyle held a balloon 8 feet off the ground.
Ava is standing 15 feet directly to the right of Kyle.
So, height = 8 ft and distance = 15 ft
Using Pythagoras theorem
x² = 8² + 15²
x² = 64+ 225
x = 17 unit
Thus, the value of x is 17 unit.

A community swimming pool has a deep end and a shallow end. The volume of water in the deep end can be represented by (2x2+12x+10) ft3 and the volume of the water in the shallow end can be represented by (4x2−100)ft3.
Write an expressions (simplified) that represents the total volume of the water in the pool in ft 3
The total volume of water in the pool is (6x² + 12x - 90) ft³.
What is Volume?Volume is a three-dimensional quantity used to calculate a solid shape's capacity. That means that the volume of a closed form determines how much three-dimensional space it can fill.
A fish tank, for example, is 3 feet long, 1 foot wide, and 2 feet tall. To calculate the volume, multiply the length by the breadth by the height, which is 3x1x2, which equals six.
Given:
The volume of water in the deep end can be represented by
= (2x² + 12x + 10) ft³
and, the volume of the water in the shallow end can be represented by (4x² −100) ft³.
The total volume of water in the pool = ( 6x^3 + 12x^2 - 90x ) ft^3
So, The total volume of water in the pool
= volume of water in the deep + volume of the water in the shallow end
= (2x² + 12x + 10) + (4x² −100)
= 2x² + 4x² + 12x + 10 - 100
= 6x² + 12x - 90

Why were the Great Pyramids built? How large of an undertaking was this?
Answer:
I only know the first one well. I don't want to answer the others and maybe give false info.
Step-by-step explanation:
Egyptians were very well known to be very interested in Spirits and Gods.
Their whole dynasty was built on the dawn of their Gods. There were many, like the Greek and Roman Gods. One of the sun, one of the underworld....etc..
The pharaohs believed themselves to be god. (Due to their immense power)
Egyptians believed that after death there was an Afterlife. In that afterlife, there was games, other people (spirits), homes (graves). This might sound weird but in the graves especially of Pharaohs they placed beds, tables, chairs, games..etc..

Values of the elements in the Matrix are A₂₁ = -2, A₂₂ = 0, A₂₃ = 4, A₃₃ = 5.
What is the matrix?
A collection of numbers lined up in rows and columns to form a rectangular array is called a matrix. The elements, or entries, of the matrix, are the integers. In addition to many other areas of mathematics, matrices have numerous applications in the fields of engineering, physics, economics, and statistics.
given, the sum of each row is equal to the sum of each column equals the sum of all diagonals.
Since, the sum of column C₁ = 3 + -2 + 1 = 2
the sum of Row R₁ = 3 + A₂₁ + 1 = 4 + A₂₁
Since this is equal to the sum of column C₁
thus, 4 + A₂₁ = 2
A₂₁ = -2
the sum of column C₂ = A₂₁ + A₂₂ + 4
C₂ = -2 + A₂₂ + 4
C₂ = A₂₂ + 2
Since this is equal to the sum of column C₁
2 = A₂₂ + 2
A₂₂ = 0
the sum of Row R₂ = -2 + A₂₂ + A₂₃
R₂ = -2 + 0 + A₂₃
Since this is equal to the sum of column C₁
2 = -2 + A₂₃
A₂₃ = 4
the sum of Row R₃ = -1 + 4 + A₃₃
R₃ = -3 + A₃₃
Since this is equal to the sum of column C₁
2 = -3 + A₃₃
A₃₃ = 5
therefore, the values of the matrix's elements are A₂₁ = -2, A₂₂ = 0, A₂₃ = 4, A₃₃ = 5.
