Answer:
37
Step-by-step explanation:
First, we need to find the sum of all the numbers of the dice. The expression 3(1 + 2 + 3 + 4 + 5 + 6), or 3(21) does that for us. 3 × 21 = 63. So the sum of all of the numbers of the dice is 63. But we already know 7 of the numbers there: 2, 3, 1, 6, 5, 4, 5. In the expression 3(21), we counted these numbers as well. So now we can add these 7 numbers together then subtract them from 3(21), or 63. We can write the expression 3(21) - (2 + 3 + 1 + 6 + 5 + 4 + 5), or 3(21) - 26 = 63 - 26 = 37.
Answer:
136 cm²
Step-by-step explanation:
I'm going to split the net into:
2x 7 cm by 2 cm rectangles
2x 6 cm by 7 cm rectangles
2x 6 cm by 2 cm rectangles
The 2x means there's 2 of them.
Let's find the area of the 2x 7 cm by 2 cm rectangles:
2*7*2=
4*7=
28 cm²
Let's find the area of the 2x 6 cm by 7 cm rectangles:
2*6*7=
2*42=
84 cm²
Let's find the area of the 2x 6 cm by 2 cm rectangles:
2*6*2=
12*2=
24 cm²
Adding all these areas together gives us the surface area of the net:
28+84+24=136 cm²
The volume of box B is (A) 864 cubic meters.

What is volume?</h3>
- The amount of three-dimensional space enclosed by a closed surface is expressed as a scalar quantity.
- For example, the space occupied or contained by a substance or 3D object.
- Volume is frequently mathematically quantified using the SI-derived unit, the cubic meter.
To find the volume of box B:
- We have been assigned a volume of 32 cubic meters.
- The cubic root of 32 yields the box's dimensions, which are 3.1748 x 3.1748 x 3.1748 meters.
- Meters when the dimensions are tripled: 9.5244 x 9.5244 x 9.5244
= 864 cubic meters.
Therefore, the volume of box B is (A) 864 cubic meters.

Answer:
208
Step-by-step explanation:
Given that;
Given that;
y= a(1 - b)^t
Where;
wherein y is the final amount, a is the original amount, b is the decay factor, and x is the amount of time that has passed.
To obtain the constant b,
y= ae^-bt
Substituting values;
1000 = 3000 e^-b(50)
1000/3000 = e^b(50)
0.33 = e^b-(50)
ln (0.33) = ln(e^b(-50))
-1.1 = -50b
b= 1.1/50
b= 0.022
After two hours or 120 minutes;
y= 3000(1 - 0.022)^120
y= 207.8661772
y= 208
Answer:
y = 4
since you cant have y = 0x + 4, you drop the x and have a straight line (slope of 0) that runs all along the y point of 4.
