$10 in = 0.83 ft= \frac{5}{6} ft\\
A=6* (\frac{5}{6}) ^{2}=4.17$

So the answer is A. 4.17 sq ft.

Answer: A. 4.17 sq ft

Step-by-step explanation:

The total surface area of cube is given by :_

$T.A.=6(side)^2$

Given: The side of cube = 10 in.

We know that 1 feet = 12 inch

∴ $1\ in.=\frac{1}{12}\ ft$

Therefore, the side of cube = $10\times\frac{1}{12}\ ft=\frac{10}{12}\ ft$

Then the total surface area of cube is given by :_

$T.A.=6(\frac{10}{12})^2\\\\=6(\frac{100}{144})\\\\=4.16666666667\approx4.17\ sq\ ft$

Simplify the expression below. (–7x + 4) – (2x – 8)

Elanso [62]

Answer:

- 9x + 12

Step-by-step explanation:

Given

(- 7x + 4) - (2x - 8) ← distribute parenthesis by 1 and - 1

= - 7x + 4 - 2x + 8 ← collect like terms

= - 9x + 12

The differential equation of a certain system is 20⁢y′⁢′+c⁢y′+80⁢y=0

Sholpan [36]

Answer:

c=80

Step-by-step explanation:

Based on my reading the critical damping occurs when the discriminant of the quadratic characteristic equation is 0.

So let's see that characteristic equation:

20⁢r^2+c⁢r+80⁢=0

The discriminant can be found by calculating b^2-4aC of ar^2+br+C=0.

a=20

b=c

C=80

c^2-4(20)(80)

We want this to be 0.

c^2-4(20)(80)=0

Simplify:

c^2-6400=0

Add 6400 on both sides:

c^2=6400

Take square root of both sides:

c=80 or c=-80

Based on further reading damping equations in form

a⁢y′⁢′+b⁢y′+C⁢y=0

should have positive coefficients with b also having the possibility of being zero.

HELP ME PLEASE True or false: z=−5 is a solution to the inequality −2|z−3|<−20.

Dovator [93]

your question: 

True or false: z=−5 is a solution to the inequality −2|z−3|<−20.

answer: 

-2|z-3|<-20

-------. -----

-2 -2

|z-3|<10

equation 1: equation 2:

z-3<10. z-3>-10

z<13 z>-13

So false, z=-5 is not a solution to the inequality.

hope this helps, have a great day! :)

A jar of natural peanut butter normally cost four dollars today it's on sale for $3.60 what is the percentage of the discount

kakasveta [241]

$4 is the original price of the jar consisting of peanut butter so therefor it = 100%. It's for sale at $3.60, so we divide $4 by 100% so we get the percentage for each cent and then we times it by 3.60 to get the percentage for $3.60 which is 90%. Now we subtract 90% from 100% to get the discounted percentage for 40cents :)
