Answer: 17.928666 inches

Step-by-step explanation:

It moves at 2.394 inches per minute. To find the distance you would just multiply by the time. This is because the formula for distance is:

distance = rate x time

So you have: 2.394 x 7.489 = 17.928666 inches

Answer:

d=17.928666 inches

Step-by-step explanation:

The rate is 2.394 inches per minutes

The time is 7.489 minutes

We can find the distance using

d=rt where d is the distance, r is the rate and t is the time

d = (2.394) * (7.489)

d=17.928666 inches

(All problems are connected with eachother.) Directions: Mr. Clark's backyard vegetable garden is circular, centered at point A,

jonny [76]

Check the picture below. part 1 and 2 are there.

part 3)

$\bf \textit{arc's length}\\\\
s=\cfrac{r\theta \pi }{180}\implies \cfrac{180s}{r\pi }=\theta \qquad 
\begin{cases}
\theta =\textit{angle in degrees}\\
r=radius\\
----------\\
s=12.2\\
r=\sqrt{\frac{315}{\pi }}
\end{cases}
\\\\\\
\cfrac{180\cdot 12.2}{\pi \sqrt{\frac{315}{\pi }}}=\theta \implies 69.8075^o\approx \theta \implies 70^o\approx\theta$

$\bf \textit{area of a sector of a circle}\\\\
A=\cfrac{\theta \pi r^2}{360}\quad 
\begin{cases}
r=\sqrt{\frac{315}{\pi }}\approx 10\\
\theta \approx 70
\end{cases}\implies A=\cfrac{70\cdot \pi \cdot 10^2}{360}$

Let U={b, c, d, e, f, g, h} and A={b, f, g, h}. Use the roster method to write the set A'

podryga [215]

The roster method to write the set A' will be {c, d, e}.

Sets are groups of clearly specified components. The number of items in a finite set is denoted by a curly bracket.

Let U = {b, c, d, e, f, g, h} and A = {b, f, g, h}.

The roster method to write the set A' will be given as,

A' = U - A

A' = {b, c, d, e, f, g, h} - {b, f, g, h}

A' = {c, d, e}

The roster method to write the set A' will be {c, d, e}.

More about the sets link is given below.

How would i do both of these, show work pls

Alex_Xolod [135]

Answer:

-12.5%

-14.29%

Step-by-step explanation:

For #2:

Original price is $2.00, that price decreased by $0.25 is $1.75. First figure out what $0.25 out of $2.00 is as a percent:

0.25/2.00 = 0.125 = 12.5%

Then, since the price DECREASED by $0.25, the percent would be negative.

For #4:

Original price is $3.50, that price decreased by $0.50 is $3.00. Like #2, you need to figure out what $0.50 out of $3.50 is as a percent:

0.50/3.50 = 0.1429 = 14.29%

Then, since the price DECREASED by $0.50, the percent would be negative.

What are the solutions of 3x2 + 6x + 6 = 0<br><br> –2 ± i<br> –2 ± 2i<br> –1 ± i<br> 1 ± i

velikii [3]

C) Quick way:

3x^2+6x+6=0 ---> x^2+2x+2=0,

sum of solutions is the 'x' coefficient multiplied by -1: (-1+i)+(-1-i)=-2-->2
Product is the independent term: (-1+i)(=1+i) = (-1)^2-i^2 = 1+1=2

Takes longer to write it down!
