Daddy spends 50% of his salary on rent, 1/4 of the remainder on groceries and keeps the rest. If he keeps $4800, how much is his salary
Answer:
$19,200
Step-by-step explanation:
Daddy spent 3/4 of his salary on things.
This means that you can multiply 4,800*4 to find the salary as 4,800 is 1/4 of the total salary.
4,800*4=19,200

Volume is the measure of 3 dimensional space. The volume of the considered cylinder whose radius is of 3 units, and height of 6 units is V = 54π cubic units.
What is the volume of a cylinder?Suppose that the radius of considered cylinder be 'r' units.
And let its height be 'h' units.
Then, its volume is given as:
[tex]V = \pi r^2 h \: \rm unit^3[/tex]
For this case, we're specified that:
Radius of the considered cylinder = r = 3 unitsThe height of the considered cylinder = h= 6 units.Thus, the volume of this cylinder is:
[tex]V = \pi r^2 h = \pi (3)^2 (6) = 54\pi\: \rm unit^3[/tex]
Thus, the volume of the considered cylinder whose radius is of 3 units, and height of 6 units is V = 54π cubic units.

The work of a student to solve the equation 3(3x − 4) = 8 + 2x + 5 is shown below: Step 1. 3(3x − 4) = 8 + 2x + 5 Step 2. 6x − 7 = 13 + 2x Step 3. 6x − 2x = 13 + 7 Step 4. 4x = 20 Step 5. x = 5 In which step did the student first make an error and what is the correct step? (1 point) Step 2, 9x − 12 = 13 + 2x Step 2, 9x − 4 = 2(6 + x + 3) Step 3, 6x + 2x = 13 + 7 Step 3, 6x − 2x = 13 − 7
Answer:
(a) Step 2. 9x -12 = 13 +2x
Step-by-step explanation:
The distributive property says a factor outside parentheses multiplies each term inside parentheses. It is an error to do addition of the factor, or to miss multiplying a term.
In Step 2 of this "solution", the factor of 3 is erroneously added to each coefficent inside parentheses. It should be multiplied.
Correct Step 2: 9x -12 = 13 +2x
__
The rest of the solution should be ...
Step 3: 9x -2x = 13 +12
Step 4: 7x = 25
Step 5: x = 25/7

Check
3(3(25/7) -4) = 8 + 2(25/7) +5

Moses is creating a large cube sculpture for a city park. He first makes a smaller cube to use as a rough model of his sculpture. The edge lengths of the model are each 25 in. The edge lengths of the sculpture will be 3 times the model's edge lengths. How many times as large is the volume of the sculpture than the volume of the model? Show your work.
From the calculations, the volume of the sculpture is 27 times the volume of the model.
Volume of a cubeThe volume of a cube is obtained using the formula;
Volume = l^3
Where l is the length of each edge. We should note that the lengths of all the edges in a cube are equal.
Hence,
volume of the model = (25)^3 = 15625 in^3
volume of the sculpture = (3 * 25)^3 = 421875 in^3
Ratio of the volume of the sculpture to the volume of the model = 421875 in^3/15625 in^3
= 27:1
Hence, the volume of the sculpture is 27 times the volume of the model.

Which expression is equivalent to -3x+9?
A.-3(x+9)
B.-3(x-3)
C.-3(x+12)
D.3(-x-3)
Explanation:
Use the distributive property to pull out the -3
When going in reverse like this, we divide each term by -3
-3x/(-3) = x
9/(-3) = -3
So -3x+9 = -3(x-3)
We can verify this by multiplying the -3 outside with each term inside
-3 times x = -3x
-3 times -3 = 9
This shows how -3(x-3) turns into -3x+9 again.

Work out the value of x
Answer:
Step-by-step explanation:
Add 87° + 63° = 150°
then set up this equation:
x + 150° = 180°
x + 150° = 180°
- 150° = -150°
x = 30°
When you add 87 + 63 + 30
it should give you 180° if it doesnt equal 180° then recheck your work.
