Two identical number cubes are shown in the picture below. The edge length of these number cubes is 4 centimeters: What is the combined volume of the 2 dice shown above in cubic centimeters?
Answer:
d. 128 cm^3
Step-by-step explanation:
to find the volume its length time width times heights; so 4 cm times 4 cm time 4 cm which is 64. Since the dice are the same size you add 64 cm^3 to 64 cm^3 to get 128 cm^3
okay yes i need a lot of help okay
Answer:
either 78.4cm or 288.4cm
Step-by-step explanation:
rectangle area
A = 15x4
A = 60
Area of 2 triangles
A = 4.6x4/2
A = 9.2x2
A = 18.4
18.4 + 60 = 78.4cm
Maybe the answer
Area of 2 rectangles
A = 15x4
A = 60
A = 15x14
A = 210
Area of 2 triangles
A = 4.6x4/2
A = 9.2x2
A = 18.4
60 + 210 + 18.4 = 288.4cm
either answer hope one is right
Answer:
228.4
Step-by-step explanation:
Both triangle surface:
4x4.6 and then divide by 2 = 9.2
That will be the surface for one triangle
But there are two triangles so we times that by 2
That will be 18.4
Both big rectangle surface: (the top and bottom ones)
15x5=75
But we have two rectangles
So we times that by two and the answer will be =150
Smaller rectangle: (the one between two triangles)
4x15=60
Okay, now we add them all up, the triangles and rectangles
60+150+18.4=228.4

Which relationship is always correct for the angles x, y, and z of triangle ABC? (1 point)
A triangle ABC has angle ABC labeled as y, angle ACB labeled as z, and the exterior angle at A labeled as x.
x + z = y
y + z = x
x + y + z = 180 degrees
x + y + z = 90 degrees

Coach Cliffman made a deposit of $1,800 into an account that earns 2% annual compound interest. Find the amount of interest that Coach Cliffman earned after 3years.
Answer: 5508$
Step-by-step explanation:
So to find interest your formula is this:
Int=interest rate (percent)*principal
So your problem would be: int=.02*1800
This equals 36. Since its interest, you add your interest (36) and your principal (1800) and get 1836. Now, since you need to find the interest for 3 years, you multiply 1836 by 3.
Step-by-step explanation:
