Answer:

the walkway is 2 feet wide

Step-by-step explanation:

x=walkway width

(12+2x)(16+2x)=320

192+24x+32x+4x^2=320

simplify

4x^2+56x+192=320

4x^2+56x-128=0

divide by 4

x^2+14x-32=0

factor

(x+16)(x-2)=0

x=-16

x=2

The relationship between women’s whole-number shoe sizes and foot lengths is an arithmetic sequence, where an is the foot length
ad-work [718]

Answer:

The explicit formula for Arithmetic Sequence is a_n=7.02+0.33n

Step-by-step explanation:

Given: Foot length & shoe size in AP.

           a_n is foot length and n is shoe size.i.e., a_{12}=11\:and\:a_7=9.33

To find: Formula for Arithmetic sequence .i.e., a_n

From question,

a_{12}-a_7=11-9.33=1.67

Also, we know that

a_{12}=a_7+5d\\5d=a_{12}-a_7\\5d=1.67\\d=\frac{1.67}{5}\\\\d=0.33        

Now, consider

a_7=a_1+6d\\a_7=a+6d\\a=a_7-6d\\a=9.33-6\times0.33\\a=9.33-1.98\\a=7.35

Thus using formula of a_n we get,

a_n=a+(n-1)d\\a_n=7.35+(n-1)\times0.33\\a_n=7.35+0.33n-0.33\\a_n=7.02+0.33n

Therefore, The explicit formula for Arithmetic Sequence is a_n=7.02+0.33n

The profit earned by a hot dog stand is a linear funsion of the number of hot dogs sold.It cost the owner $48 dollars each morni
Delvig [45]

Answer:

Step-by-step explanation:

If he earns $2 per hot dog sold, then the algebraic expression for this is 2x, where x is the number of hot dogs sold. If he has to put out $48 to buy the supplies, that is represented as -48. The function, then, that represents the profit earned by selling the hot dogs is

y = 2x - 48

How does the volume of a cone change if the height is doubled ?
dexar [7]
If you keep the radius the same and double the height, you find that by experimentation with this a few times, doubles your volume as well.  That means that instead of 1/3 pi r^2 h, we will have 2/3 pi r^2 h.  Your answer B.
