Natalee wanted to demonstrate the volume of a square pyramid. To do this, she took a hollowed out pyramid that has a base of 25 square inches and a height of 5 inches and filled it with water. She then dumped this water into a hollowed out cube that has a volume of 125 cubic inches. Enter the amount of times that she will need to dump the water from the pyramid into the cube to completely fill the cube
Answers
Answer:
The answer is below
Step-by-step explanation:
Natalee transferred water from a square pyramid to a cube. To calculate how many times she will need to dump the water from the pyramid into the cube to completely fill the cube, we divide the volume of the cube by the volume of the square pyramid. Hence:
Number of times = volume of cube / volume of pyramid
The perimeter of the pyramid base = 25 in, hence the length of one side of the bae = 25 / 4 = 6.25 in
Volume of square pyramid = base² × (height / 3) = (6.25 in)² * (5 in / 3) = 65.1 in³
Volume of cube = 125 in³
Number of times = 125 in³ / 65.1 in³ = 1.92
The amount of times that she will need to dump the water from the pyramid into the cube to completely fill the cube is 1.92.
What is volume?The capacity of a container of any shape is called the volume.
Natalee transferred water from a square pyramid to a cube. Then,
Given is the perimeter of the pyramid base = 25 in
So, the length of one side of the base b= 25 / 4 = 6.25 in
Volume of square pyramid = b² × (h/ 3) = (6.25 in)² * (5 in / 3) = 65.1 in³
Volume of cube = 125 in³
Number of times = volume of cube / volume of pyramid
Number of times = 125 in³ / 65.1 in³ = 1.92

Answer:
-121X
Step-by-step explanation:
In an equation, x= the slope, and the number that comes after is the y intercept. So 200 would be where the line starts, and would have a negative slope of -121x

Step-by-step explanation:
Set the equations equal to each other since the lines are parallel.
(x+20)=(4x-5)
-x +5 -x +5
25/3 = 3x/3
x = 25/3
The equation will be (x+20)°+(4x-5)°=180.
(x+20)+(4x-5)=180
5x+15=180

You work as a cashier for a grocery store and earn $5 per hour. You also mow lawns and earn $10 per hour. You want to earn at least $50

Which system of inequalities, along with y0 andx
0, would you use to solve the real-world problem?
Answers
The required inequalities are x + y ≤ 10 and 5x + 10y ≥ 50
What is an inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given that, You work as a cashier for a grocery store and earn $5 per hour. You also mow lawns and earn $10 per hour. You want to earn at least $50 per week, but would like to work no more than 10 hours per week.
Let, you work at grocery story (x), and you work mowing lawns (y)
You want to work no more than 10 hrs
So, first inequality will deal with hrs.
x + y ≤ 10....(i)
A less than or equal to sign tells that you do not want to work more than 10 hrs, but you can still work 10 hrs, so we include the equal sign as well.
And,
Grocery store (x) earning $5 per hr and lawn mowing (y) earning $10 per hr, making at least $50...
Now we will make an inequality dealing with the $
5x + 10y ≥ 50.....(ii)
A greater than or equal to sign tells that, you want to make 50 or more, so we include the equal sign.
So, the inequalities are :
x + y ≤ 10
5x + 10y ≥ 50

Layla emptied out her change jar to buy a new binder for school. She found 147 coins consisting of dimes and nickels that totaled $11.65. Write a system of equations that could be used to determine how many dimes, d, and how many nickels, n, Layla had in her change jar.
Answers
Answer:
d + n = 147
0.10d + 0.05n = 11.65
d = 86, n = 61
Step-by-step explanation:
Let
Number of dimes = d
Number of nickels = n
Total coins = 147
Total value = $11.65
d + n = 147 (1)
0.10d + 0.05n = 11.65 (2)
From (1)
d = 147 - n
Substitute d = 147 - n into
0.10d + 0.05n = 11.65
0.10(147 - n) + 0.05n = 11.65
14.7 - 0.10n + 0.05n = 11.65
- 0.10n + 0.05n = 11.65 - 14.7
-0.05n = -3.05
n = -3.05 / -0.05
= 61
n = 61
Substitute n = 61 into
d + n = 147
d + 61 = 147
d = 147 - 61
d = 86

how to solve using Substitution or Elimination?
y=3x-1
y=2x+2
Answers
By elimination:
y = 3x - 1
y = 2x + 2
Subtract the second equation from the first
0 = x - 1
y = 2x + 2
Subtract the first equation from the second
0 = x - 1
y = x + 3
Subtract the first equation from the second again
0 = x - 1
y = 4
Subtract x from both sides of the first equation
- x = - 1
y = 4
Divide the first equation by (-1)
x = 1
y = 4
So, the solution is x = 1 and y = 4 {or: (1, 4)}PLEASEE answer correctly !!!!!!!!!!!! Will mark brainliest !!!!!!!!!!!!!!!!!!!
