Slope = (4 + 8)/(-1 - 2)
slope = 12 / -3
slope = -4
answer
C. -4
Answer:
72
Step-by-step explanation:
90 = 125%
90 ÷ 5 = 25% = 18
18 x 4 = 72
EXPLANATION
If a_1 = 5 and a_n = n*a_n-1 - 4 the value of a_3 is given by the following relationship:
The answer is 8
9514 1404 393
Answer:
21, 3
Step-by-step explanation:
Let the first and second numbers be x and y, respectively. Then we have ...
x + y = 24 . . . . their sum is 24
x = 8y -3 . . . . . the first is 3 less than 8 times the second.
Substituting for x in the first equation, we have ...
(8y -3) +y = 24
9y = 27 . . . . . . . . add 3
y = 3 . . . . . . . . . . divide by 9
x = 8(3) -3 = 21
The two numbers are 21 and 3.
Answer:
108 cubes
Step-by-step explanation:
A rectangular prism with a volume of 4 cubic units is filled with cubes with side lengths of 1/3 . How many 1/3 unit cubes does it take to fill the prism?
Step 1
We find the volume of the cubes
Side length = 1/3 units
Volume of a cube = Side length ³
Hence,
(1/3 units)³ = 1/27 cubic units
Step 2
A rectangular prism with a volume of 4 cubic units.
The number of 1/3 unit cubes that would fill this rectangular mrism is calculated as:
4 cubic units ÷ 1/27 cubic units
= 4 ÷ 1/27
= 4 × 27/1
= 108 cubes
