Bilal has made a box in the shape of a cuboid with sides 4cm, 5cm and 32cm. He wants to make another different shaped box but with the same volume. This box will have a height of 10cm and a square base. What will be the length on the base?
Answer:
64
Step-by-step explanation:
v=l×b×h
4×5×32
640
v=hb
640=10x
10x=640
x=640/10
x=64
Answer:
4 x 5 x 32 = 640
640/10=64
since length squared = area of square we square root
64 square root is 8
10 x 8 x 8 = 4 x 5 x 32

The graphed line shown below is y = negative 3 x + 6. On a coordinate plane, a line goes through points (1, 3) and (2, 0). Which equation, when graphed with the given equation, will form a system that has no solution? A)y = 3 x + 6 B)y = negative 3 (x + 6) C)y = negative 3 (x minus 2) D)y = 3 (x minus 2).
Answer:
y = -3 (x + 6) when graphed with the given equation, will form a system that has no solution
Step-by-step explanation:
Given line equation: [tex]y=-3x+6[/tex]
We are supposed to find Which equation, when graphed with the given equation, will form a system that has no solution.
We know that a system of two linear equations has no solution if and only if the two equations have the same slope, but not the same y-intercept.
General equation of line = [tex]y=mx+c[/tex]
A)y = 3 x + 6
So, Slope = 3
B)y = -3 (x + 6)
y=-3x-18
So, slope=-3
C)y=-3(x-2)
y=-3x+6
So, Slope = -3
D)y=3(x-2)
Slope =3
So, B has the same slope but different intercept
So,y = -3 (x + 6) when graphed with the given equation, will form a system that has no solution
Answer:
B) y= -3(x+6)

D 2,000 X 100
write an equation that can be used to find the value of x.
Answer:
x=29
Step-by-step explanation:
Since you have a 90° angle drawn, all of those angles added together has to equal 90. To solve this you add all of them to get 3x+3=90°. First, subtract the 3 to get the x variable on one side. After this, you get 3x=87. Then, divide by 3 to get x=29. To check this, plug in 29 for x in the equation and add them altogether, it should equal 90° :)
A bag contains 21 red marbles, 4 white marbles, and 3 gray marbles. Do you randomly pick out a marble recorded color and put it back in the bag. You repeat this process 84 times. How many white or gray marbles do you expect to get?
Answer:
28
Step-by-step explanation:
you add 21, 4, and 3 to find the total
then you find how many are white or gray
7/28= 1/3
1/3 times 84
84 times 1 divided by 3
84/3

x=3 (divide 3)
Answer:
4x=20 and x+7=19
Step-by-step explanation:
4x=20. To solve this you divide both sides by 4 and get x=5.
x+7=19. To solve this you subtract both sides by 7 and get x=12

In mathematics, the term which is being divided is called a dividend. The term by which the dividend is getting divided is called a divisor. The quotient is the term we get after dividing the dividend by a divisor.
Here in this case, the dividend is written.
-x² x x
which in the equation form is written as
-x² + x + x
add the x terms to simplify
-x² + 2x
The divisor is given as x, divide the equation by x:
(-x² + 2x)/x
(-x²/x) + (2x/x)
-x+2
Which is the quotient.

The following blueprint of a kitchen has dimensions of 8 inches by 8 inches. The island has been highlighted in red.
The island's actual dimensions are feet by feet. If the scale of the blueprint is 1 inch = feet, what are the dimensions of the island on the blueprint?
Answer:
so assuming 1 3/4 feet by feet means 1 3/4 feet by 1 foot,
island actual dimentions=1 3/4 feet by 1 foot
scale=1 inch=1 feet
logically, blueprints are smaller so for every real foot, 1 inch is drawn on the scale
so change every foot to inch
so the island on the blueprint=1 3/4 inch by 1 inch

What is the value for y?
Enter your answer in the box.
Answer:
y = 14
Step-by-step explanation:
The sum of the angles in a triangle add to 180 degrees
50 + 2x+ 5y + 10 = 180
We know that 2x = 50 since they are the base angles of sides that have the same length, they must be the same
50 + 50 + 5y+10 =180
Combine like terms
110 + 5y =180
Subtract 110 from each side
110+5y-110 = 180-110
5y = 70
Divide each side by 5
5y/5 =70/5
y = 14
5) What is the difference between a debit card and a credit card? What are some advantages and disadvantages of using a credit card?
Answer:The difference is that a debit card has a Visa® or Mastercard® logo on its face. When you use a debit card, the money is deducted from your checking account.

The required volume of the given cylinder is 2260.8 cubic centimeters.
What is the volume of a cylinder?The volume of a cylinder is equal to the product of the area of the circular base and the height of a cylinder. The volume of a cylinder is defined as the space occupied by the cylinder as the volume of any three-dimensional shape is the space occupied by it
V = πr²h
where 'r' is the radius of the base (circle) of the cylinder
'h' is the height of the cylinder
As per the given question, we have data as:
Radius(r) = 6 cm
Height(h) = 20 cm
Volume of cylinder = πr²h
Volume of cylinder = 3.14 × (6)² × 20
Volume of cylinder = 3.14 × 36 × 20
Volume of cylinder = 2260.8 cm³
Thus, the required volume of the given cylinder is 2260.8 cubic centimeters.

Discount amount=Discount % of MP
= 30% of 45
=$13.5
Again,
Sale price(SP)=MP-Discount
= 45-13.5
=$31.5
