Answer:

P = 45.16 meters

Step-by-step explanation:

Let the perimeter by P

31% of P is 14 meters

P*31% = 14 meters

Change to decimal form

P*.31 = 14

Divide each side by .31

P*.31/.31 = 14/.31

P =45.16129032

Rounding to the nearest hundredth

P = 45.16 meters

Answer:

I think the answer is C. 324 but i'm not sure. lemme know if i'm wrong and what the correct answer is

Step-by-step explanation:

The area of the given Circle C is; 324π

From the attached diagram, we see that;

WX is the radius of circle X and is equal to 8 units

Similarly, ZY is radius of circle Y and is equal to 10 units.

Thus, diameter of circle X = 8 * 2 = 16 units

Diameter of circle Y = 10 * 2 = 20 units

Thus;

Diameter of circle C = 20 + 16 = 36 units

Area of Circle C = π * 36²/4

Area of Circle C = 324π

Answer:

The answer is "[tex]\bold{y=4x+17}[/tex]".

Step-by-step explanation:

In the given statement the graph is missing. So, the correct solution to this question can be described as follows:

Given

graph point: [tex]\bold{(2, 25)}[/tex]

Line points: [tex]\bold{(0,10), \ \ and \ \ (10,50)}[/tex]

The Formula of slope:

[tex]\boxed{M= \frac{y_2-y_1}{x_2-x_1}}\\\\\Rightarrow x_1= 0, y_1= 10 \\\\\Rightarrow x_2= 10, y_2=50\\\\\Rightarrow M= \frac{50-10}{10-0}\\\\\Rightarrow M=\frac{40}{10}\\\\\Rightarrow M= 4\\[/tex]

Assuming  point: (x,y)

Graph point: (2,25)

M= 4

Equation:

[tex]\Rightarrow \frac{25-y}{2-x}=4\\\\\Rightarrow 25-y=4(2-x)\\\\\Rightarrow 25-y=8-4x\\\\\Rightarrow y= 4x-17\\[/tex]

Answer:

Step-by-step explanation:

let length of first piece = x in

length of second piece = 2x

length of third piece = 5x

x+2x+5x= 16

8x =16

x =16/8

x=2

length of :

first piece =2 inches

second piece = 4 inches

third piece = 10 inches..

please mark me as the brainliest..

Answer:

2, 4, 10 in

Step-by-step explanation:

The first piece is x thus the second piece is 2x ( twice as long as first ) and

the third piece is 5x ( five times as long as the first )

Add the 3 together and equate to 16

x + 2x + 5x = 16, that is

8x = 16 ( divide both sides by 2 )

x = 2

Thus

first piece = x = 2 in

second piece = 2x = 2 × 2 = 4 in

third piece = 5x = 5 × 2 = 10 in

Step-by-step explanation:

Answer:

x = 3/2            x = -5/2

Step-by-step explanation:

(2x+3) ^2 - 4(2x+3) - 12 = 0

Let m = 2x+3

m^2 - 4m - 12 = 0

Factor

(m-6) (m+2) = 0

Using the zero product property

m-6 = 0    m+2 =0

m = 6    m = -2

Substitute m = 2x+3 back into the equation

2x+3 = 6        2x+3 = -2

2x = 3            2x = -5

x = 3/2            x = -5/2

Answer:

Option A

Step-by-step explanation:

A type II error occurs when the researcher fails to reject the bull hypothesis when it is false.

In this study, the

null hypothesis is H0:µ = 0.82 while the alternative hypothesis is H1:µ > 0.82

Thus, the type II error will be that the fish is accepted by the FDA when in fact it had more than 0.82 ppm of mercury.

The data table is attached below.

Step-by-step explanation:

The average of a set of data is the value that is a representative of the entire data set.

The formula to compute averages is:

[tex]\bar x=\frac{1}{n}\sum\limits^{n}_{i=1}{x_{i}}[/tex]

Compute the average for drop 1 as follows:

[tex]\bar x_{1}=\frac{1}{3}\times[10+11+9]=10[/tex]

Compute the average for drop 2 as follows:

[tex]\bar x_{2}=\frac{1}{3}\times[29+31+30]=30[/tex]

Compute the average for drop 3 as follows:

[tex]\bar x_{3}=\frac{1}{3}\times[59+58+61]=59.33[/tex]

Compute the average for drop 4 as follows:

[tex]\bar x_{4}=\frac{1}{3}\times[102+100+98]=100[/tex]

Compute the average for drop 5 as follows:

[tex]\bar x_{5}=\frac{1}{3}\times[122+125+127]=124.67[/tex]

The data table is attached below.

The average of the numbers in the data table will be 10, 30, 59.33, 100, and 124.67.

The average for drop 1 will be:

= 1/3 × (10 + 11 + 9)

= 10

The average for drop 2 will be:

= 1/3 × (29 + 31 + 30)

= 30

The average for drop 3 will be:

= 1/3 × (59 + 58 + 61)

= 59.33

The average for drop 4 will be:

= 1/3 × (102 + 100 + 98)

= 100

The average for drop 5 will be:

= 1/3 × (122 + 125 + 127)

= 124.67

We know that i^2 = -1 so replace it

Answer:

The sum of the first 650 terms of the given arithmetic sequence is 2,322,775

Step-by-step explanation:

The first term here is 4

while the nth term would be ai = a(i-1) + 11

Kindly note that i and 1 are subscript of a

Mathematically, the sum of n terms of an arithmetic sequence can be calculated using the formula

Sn = n/2[2a + (n-1)d)

Here, our n is 650, a is 4, d is the difference between two successive terms which is 11.

Plugging these values, we have

Sn = (650/2) (2(4) + (650-1)11)

Sn = 325(8 + 7,139)

Sn = 325(7,147)

Sn = 2,322,775

Step-by-step explanation:

So we need to divide the volume of the cylindrical glasses by the cylindrical jugs to see how many we can fill.

The equation to find the volume of a cylinder is Height*Area of Circle

To find the area of a circle is: [tex]\pi r^{2}[/tex]

In this senario "r" (radius) is 3 (d/2)

Volume for cylindrical glass:

hx[tex]\pi r^{2}[/tex]

= 10x 3.14x 3^2

= 10x3.14x 9

= 282.6[tex]cm^{3}[/tex]

Now for the cylindrical jug:  r= 5 and h=18

hx[tex]\pi r^{2}[/tex]

= 18x3.14x5^2

= 18x3.14x25

= 1413[tex]cm^{3}[/tex]

Now finally we divide them:

1413/282.6

= 5

So they can fill 5 cylindrical glasses :)

Answer:

x=1, y = -3

Step-by-step explanation:

2x -y=-11

6x + y = 3​

Add the two equations together

2x -y=-11

6x + y = 3​

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

8x  = 8

Divide by 8

8x/8 = 8/8

x= 1

Now find y

6x+y = 3

6(1) +y = 3

6+y =3

Subtract 6 from each side

6+y-6 = 3-6

y = -3
