There is a patch of lily pads on a lake. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake?

Answer:

x²+8x

Step-by-step explanation:

area of rectangle

l×w

(x+8)×x

x²+8x

The area of the rectangle is [tex]X^2 + 8X[/tex].

To find the area of a rectangle, we multiply its length by its width.

In this case, the length is (X + 8)

and the width is X.

so, we have,

Area = Length * Width

Area = (X + 8) * X

To simplify the expression, we need to distribute the X through the parentheses:

Area = X * X + 8 * X

Area = [tex]X^2 + 8X[/tex]

So, the area of the rectangle is [tex]X^2 + 8X[/tex].

Answer:

Option C

Step-by-step explanation:

Since, measure of all sides of the triangle has been given in the picture,

By applying cosine rule in the given triangle,

AC² = AB² + BC² - 2(AB)(BC)cos(B)

11² = 16² + 16² - 2(16)(16)cos(B)

121 = 256 + 256 - 512.cos(B)

121 - 512 = - 512.cos(B)

cos(B) = [tex]\frac{391}{512}[/tex] = 0.763672

B = [tex]cos^{-1}(0.763672)[/tex]

B = 40.2°

Therefore, measure of angle B is 40.2°.

Option C is the answer.

Answer: 5890 meters

Step-by-step explanation:

Given: The highest point in the mountains of Seattle is 5,833 meters above sea level.

The lowest point in the valley is 57 meters below sea level.

in integers it is represented by -57 meters. [we use negative integer to represents "below"]

Difference between the highest and lowest point = Highest point - lowest point

=  5,833 meters -(-57) meters

= (5833 + 57) meters      [a-(-b)= a+b]

= 5890 meters

Hence, the required difference = 5890 meters

Answer:

The perimeter or circumference of a half mirror = 37.68 cm

Step-by-step explanation:

We know that the perimeter of a circular shape is called the 'circumference', with the formula

When the mirror is cut into half, the diameter gets half as well.

We know that radius = r = diameter / 2 = 12/2 = 6 cm

Thus, the perimeter of half of the mirror  = C = 2πr

                                                                           = 2(3.14)6

                                                                            = 37.68 cm

Therefore, the perimeter or circumference of a half mirror = 37.68 cm

Answer: [tex]y=-5x+21[/tex]

Step-by-step explanation:

In slope intercept form : y=mx+c , m= slope , c= y-intercept.

Let [tex]L_1[/tex] be the line passing through (5, -4) and perpendicular to [tex]L_2: 2x-10y=0[/tex].

Rewrite [tex]L_2[/tex] in slope-intercept form

[tex]10y=2x\Rightarrow\ y=0.2x+0[/tex]

Here, Slope of [tex]L_2[/tex] = m = 0.2  

Let n be slope of [tex]L_1[/tex] .

Then  [tex]m\times n=-1[/tex]   [Product of slopes of perpendicular lines is -1.]

[tex]\Rightarrow\ n=\dfrac{-1}{m}=\dfrac{-1}{0.2}\\\\\Rightarrow\ n=-5[/tex]

Equation of a line that passes through (a,b) and have slope 'm' is given by :-

[tex](y-b)=m(x-a)[/tex]

So, Equation of [tex]L_1[/tex] :

[tex](y-(-4))=-5(x-5)\\\\\Rightarrow\ (y+4)=-5x+25\\\\\Rightarrow\ y=-5x+21[/tex]

The light will travel 5,580,000 miles in 30 seconds.

To understand the calculations, check below.

The distance traveled by light is represented by function.

                   [tex]d(t)=186,000t[/tex]

To find the distance traveled by light in 30 seconds.

Substitute t=30 in the given function.

            d(30) = 186,000 × 30

             d(30) = 5,580,000 miles.

Answer:

(7, -3)

Step-by-step explanation:

Solve the system of linear equations

2x − y = 11

x + 3y = −5

by elimination by addition and subtraction.  Multiply the second equation by -2, obtaining

2x - y = 11

-2x - 6y = 10

------------------

     -7y = 21, which yields y = -3

Knowing that y = -3, we can now find the value of x.  Let's use the first equation for this purpose.  Substituting -3 for y, we get:

2x - (-3) = 11, or

2x = 11 + 3, or 2x = 14.  Thus, x = 7.

The solution is (7, -3).

Answer:

They would be 5.5 miles away because if you take 20 divided by 20 to get 1 minute you would have to take 30 divided by 20 to get 1.5 miles per 1 minute. Then you would have to take 1 times 35 to get 35 minutes and you would have to take 1.5 times 35 to get 52.5. Then lastly you would take 58 miles and subtract 52.5 to get 5.5 miles therefor your answer would be 5.5 miles.

Answer:

  18

Step-by-step explanation:

There are two areas where the circles P and C overlap. One is labeled "4" and the other is labeled "3x". The sum of these two values is the number of people who like Pop and Classical  music, 13.

  4 + 3x = 13

  3x = 9 . . . . . subtract 4

  x = 3 . . . . . . divide by 3

__

We are asked to find the number of people who like two types only. The three regions where only two circles overlap are labeled x, 3x, and 6. The answer to the question is the sum of these values.

  like 2 types only: x +3x +6 = 4x +6 = 4(3) +6 = 18

18 students like two types of music only.

Answer:

a. $12,600

b. $21

c. $19

Step-by-step explanation:

a) The cost is $3000 plus $16 per book

For 600 books, we have

3000 + 16(600)

= 3000 + 9600 = $12,600

b) Cost per book will be;

12,690/600 = $21

c) for 1000

= 3000 + 16(1000)

= 3000 + 16,000 = 19,000

cost per book is 19,000/1000 = $19

Answer & Step-by-step explanation:

First write the line equation.

y=mx+b is the format where m=slope, b= y intercept

y=-2x-3

plug each x in to see if they match the point

y= -2(-2) -3 = -4 - 3 = -7 ; the point is (-2,0) so NO

y= -2(-1.5) -3= 3-3 = 0; point is (-1.5, 0) so YES it matches

y= -2(-6) -3 = 12-3 = 0; point matches so YES

y= -2(2) -3 = -4-3 = -7; point is (2, -3) so NO

y = -2(3) -3 = -6-3= -9; point matches so YES

y= -2(-4)-3 = 8-3 = 5; point is (-4, 4) so NO
