Answer:

Less than 25%

Step-by-step explanation:

1189 divided by 967 is 1.229576008...

1.229576008... multiplied by 967 is 1189

This number, 1.229576008..., is a multiplier

To be exact it increases by 22.9576008...%

That is less than 25%

<h3>Given:</h3>

This week= 967 people

Last week= 1189 people

<h3>To find:</h3>

The percentage decrease.

<h3>Solution:</h3>

\% \: decrease =  - 100 \times  \frac{(final - initial)}{initial}

\% \: decrease =  - 100  \times \frac{(967 - 1189)}{1189}

\% \: decrease =  - 100 \times  \frac{ - 222}{1189}

\% \: decrease = 18.67115223 \: \%

\% \: decrease = 18.7 \: \%

So it's less than 25%

Answer:

13) 7 + x/2 = 10

14)  2x - 5 = 7

15) 4x - 1 = 11

16) 6x - 6 = 12

17) x/3 + 10 = 12

18) 2x + 7 = 1

19) 9 + x/7 = 11

20) 8(n - 3)

Step-by-step explanation:

The quotient of x and 2 = x ÷ 2 = x/2

The product is the result of multiplying two or more other numbers

The sum is the result of adding two or more numbers

The difference is the result of subtracting one number from another

13) 7 + x/2 = 10

14)  2x - 5 = 7

15) 4x - 1 = 11

16) 6x - 6 = 12

17) x/3 + 10 = 12

18) 2x + 7 = 1

19) 9 + x/7 = 11

20) 8(n - 3)

<u>Algebra I</u>

  • Range is the set of y-values that are outputted by function f(x)

Step-by-step explanation:

According to the graph, our line's y-values span from 2 to 14. Since both 2 and 14 are open dot, they are exclusive from the range:

Interval Notation: (2, 14)

Caleb is making lemonade and cookies for the school bake sale. He has 10 cups of
Goryan [66]

Answer:

He can make only one batch of cookies.

Step-by-step explanation:

Just by mental math you can say he can make maximum one batch of cookies.

Total sugar = 10 cups

sugar used for lemonade = 2 cups

leftover sugar = 8 cups

For 1 batch of cookie sugar needed = 11/2

which means 5 and 1/2 cups

And he's just left with 8 cups of sugar after lemonade

8 - 5 1/2 = 2 1/2 which is not enough for 2nd batch

That means the maximum number of cookies batches is 1.

Another way to solve it by inequality:

2+Il/2 X <u><</u> 10

11/2 X <u><</u> 8

11X <u><</u> 16

X <u><</u> 1 6/11

So he can make only one batch of cookies.

What are the real and complex solutions of the polynomial equation? x^3-8=0. with imaginary numbers
seraphim [82]

Answer:

Solutions are 2,  -1 +  0.5 sqrt10 i  and -1 - 0.5 sqrt10 i

or 2,  -1 +  1.58 i  and -1 - 1.58i

(where the last 2 are equal to nearest hundredth).


Step-by-step explanation:

The real solution is x = 2:-

x^3 - 8 = 0

x^3 = 8

x = cube root of 8 = 2

Note that a cubic equation must have  a total of 3 roots ( real and complex in this case).  We can find the 2 complex roots by using the following identity:-

a^3 - b^3 = (a - b)(a^2 + ab + b^2).

Here  a = x and b = 2 so we have

(x - 2)(x^2 + 2x + 4) = 0

To find the complex roots we solve x^2 + 2x + 4 = 0:-

Using the quadratic formula x = [-2 +/- sqrt(2^2 - 4*1*4)] / 2

= -1 +/- (sqrt( -10)) / 2

= -1 +  0.5 sqrt10 i  and -1 - 0.5 sqrt10 i

Find the area A of the sector of a circle of radius 90 in formed by central angle 1/6 radian.
miv72 [106K]

Answer:

2121 in^{2} Rounded to the nearest inch.

Step-by-step explanation:

A = \pi r^{2}  Is the formula for a circle, but we only have a portion of a circle so we will have to adjust the formula for a part of the circle.

A = \frac{\frac{\pi }{6} }{2\pi } \pi r^{2}  The \frac{\pi }{6} is the part of the circle and the whole circle is 2\pi

\frac{\frac{\pi }{6} }{2\pi } is the same as \frac{\pi }{6}÷\frac{2\pi }{1} Which is the same as \frac{\pi }{6} x \frac{1}{2\pi } Which is the same a \frac{1}{12}

A = \frac{1}{12}\pi90^{2}

A = \frac{1}{12}(3.14)(90)(90) = 2119.5.  When you use the \pi on your calculator you get a slightly different number.  This is due to rounding.

A = 2120.575041
