The edge length of a cube is 3.5 inches. Find the surface area of the cube.
Nataliya [291]
A cube has all sides the same length, check the picture below.

since the cube is just 6 squares stacked up to each other at the edges, we can simply get the area of each square and sum them up, and that's the surface area of the cube.

(3.5 · 3.5) + (3.5 · 3.5) + (3.5 · 3.5) + (3.5 · 3.5) + (3.5 · 3.5) + (3.5 · 3.5) .

The radius of a circular disk is given as 21 cm with a maximum error in measurement of 0.2 cm. (a) Use differentials to estimate
sergiy2304 [10]

Answer with Step-by-step explanation:

We are given that

Radius of circular disk=r=21 cm

dr=0.2 cm

a.Area of circular disk=A=\pi r^2

d A=2\pi rdr

d A=2\pi (21)(0.2)=8.4 \pi cm^2

d A=8.4\times 3.14

Where \pi=3.14

d A=26.38 cm^2

b.Relative error=\frac{dA}{A}=\frac{26.38}{\pi (21)^2}

Relative error=0.0191

Percentage(%) error=0.0191\times 100=1.91%

Solve the system of linear equations by substitution. y=2x+5 and y=3x-1
Doss [256]
Plug in the second equation into the first equation for y.
y = 2x + 5 \\ y = 3x - 1 \\ 3x - 1 = 2x + 5
Now put the variable on one side and constants on the other
3x - 1  + 1 - 2x = 2x - 2x + 5 + 1 \\ x = 6
Now plug that back into one of the original equations
y = 2x + 5 \\ y = 2(6) + 5 \\ y = 12 + 5 \\ y = 17
So now you know
x = 6 \\ y = 17
Its always a good idea to check
17 = 2(6) + 5 \\ 17 = 17 \\ 17 = 3(6) - 1 \\ 17 = 17

math question, help. I got two different answers for this and I don’t know which one is correct. please include steps
Katena32 [7]

Answer:

  16/(3(x+1))

Step-by-step explanation:

We can factor the denominator of the second term, which lets us see how to combine terms:

\displaystyle\frac{7}{x+1}-\frac{5}{3x+3}=\frac{7}{x+1}-\frac{5}{3(x+1)}\\\\=\frac{3\cdot 7}{3(x+1)}-\frac{5}{3x+3}=\frac{21-5}{3(x+1)}=\frac{16}{3(x+1)}
