Answer:

320 "if rounded"

Step-by-step explanation: you find out what number times itself equals 6500 which is 80.623 "rounded to 80" then you add up all the sides "80+80+80+80" or "8x4"  which would be 320 but you have to do nearest tenth so your answer would be 322.4.

Answer:

1. Three collinear points are R, X, and Q

2. Plane V is a quadrilateral

3. The three segments are PQ, RX, and XQ

4. The two rays are Xr and QS

5. The five lines (each taken alone) are Xr, QS, PQ, RX, and XQ

Step-by-step explanation:

1. Collinear points are points that lie in or can be located on the same line

2) A quadrilateral is a four sided two-dimensional shape

3) A line segment is a line portion between two end points

4) A ray is a line with one end point that extends to infinity in a direction

5) A line is a one dimensional straight geometric figure that extends to infinity in both directions.

Answer:

4) d = 60; e = 90

5) f = 30

6) h = 120

Step-by-step explanation:

4)

d + d + d = 180

3d = 180

d = 60

e + e + e + e = 360

4e = 360

e = 90

5)

70 + (180 - 100) + f = 180

70 + 80 + f = 180

f = 30

6)

45 + 75 + (180 - h) = 180

300 - h = 180

-h = -120

h = 120

Answer:

(x,y)=(-2,-1)

Step-by-step explanation:

4x - y = -7: 8x-2y=-14

8x-2y=-14

-8x + 4y = 12

add these two:

2y=-2

y=-1

plug in the y:

-8x-4=12

-8x=16

x=-2

Answer:

$23.20 and $29

Step-by-step explanation:

We can set up a simple equation to solve this problem.

4x + 5x = 52.2

9x = 52.2

x = 5.8

To find out how much each person received, we multiply 5.8 with the ratio numbers 4 and 5. That gives us $23.20 and $29, respectively.

Answer:

Step-by-step explanation:

The 2-point form of the equation for a line is useful when you are given two points to work with:

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

The independent variable (x) is apparently "algae blooms" and is to be represented by "a". The dependent variable (y) is "number of fish" and is to be represented by "f". So, we have ...

  f = (4 -10)/(25 -10)(a -10) +10

  f = -6/15(a -10) +10

  f = -2/5a +14 . . . an equation for the scenario

Four a=4, the fish population is predicted to be ...

  f = -2/5(4) +14 = 12.4

There will be about 12 fish when there are 4 algae blooms.

==============================================

Explanation

Let x be some positive real number such that

leading to the ratio

ST:TU:UV = 6x:2x:3x = 6:2:3

Note how I effectively started with 6:2:3 and multiplied all parts of the ratio by x to get 6x:2x:3x

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

The parts of the ratio add up to the longest segment SV

ST+TU+UV = SV

6x+2x+3x = 22

11x = 22

x = 22/11

x = 2

Therefore,

Note how ST+TU+UV = 12+4+6 = 22, which is the length of SV. This helps confirm we have the correct x value.

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

The last step is to find the length of TV

TV = TU+UV

TV = 4+6

TV = 10

Or you could do

ST + TV = SV

12+TV = 22

TV = 22-12

TV = 10

[tex]B = \frac{3}{2} * 21,356[/tex]

Step-by-step explanation:

Given

Represent Jimmy with J and Bob with B

[tex]J = 21,356[/tex]

[tex]B = 1\frac{1}{2} * J[/tex]

Required

Determine the expression for B

[tex]B = 1\frac{1}{2} * J[/tex]

Substitute 21,356 for J

[tex]B = 1\frac{1}{2} * 21,356[/tex]

Convert Mixed fraction to improper

[tex]B = \frac{3}{2} * 21,356[/tex]

The above is an expression for B

Solving further, we have

[tex]B = \frac{3 * 21,356}{2}[/tex]

[tex]B = \frac{64068}{2}[/tex]

[tex]B = 32034[/tex]

Answer:

240

Step-by-step explanation:

Right now, Marlon's average is (210 + 225 + 254 + 231 + 280) / 5 = 240. To maintain that average, the sum of Marlon's scores after 6 games must be 240 * 6. Currently, the sum of Marlon's scores is 240 * 5 so he must score a 240 * 6 - 240 * 5 = 240(6 - 5) = 240 * 1 = 240 for his last game.

Answer:

Volume of toy = 63.8 in² (Approx)

Step-by-step explanation:

Given:

Height of cone (h) = 3 in

Height of cylinder (H) = 15 - 3 = 12 in

Radius (r) = 1.25

Find:

Volume of toy

Computation:

Volume of cylinder = πr²H

Volume of cylinder = (22/7)(1.25)(1.25)(12)

Volume of cylinder = 58.92 in²

Volume of cone = (1/3)πr²h

Volume of cone = (1/3)(22/7)(1.25)(1.25)(3)

Volume of cone = 4.91 in²

Volume of toy = Volume of cylinder + Volume of cone

Volume of toy = 58.92 in² + 4.91 in²

Volume of toy = 63.8 in² (Approx)

Answer:

(2·4)² = 64  /  (6*2)² = 144

Step-by-step explanation:

Follow PEMDAS :

Parenthesis first, so:

2 * 4

==> 8

Then Exponent:

8 ^2

==> 64

(2·4)² = 64

Do the same for (6:2)² :

Parenthesis first :

6 * 2

==> 12

Then Exponent:

12^2

==> 144

(6:2)² = 144

Answer:

Step-by-step explanation:

First, multiply the numbers inside the parenthesis. So

1. 2*4 = 8

2. 6*2 = 12

Next, Use the exponents

1. 8^2

2. 12^2

Finally, solve using exponents.

1. 8^2 = 64

2. 12^2 = 144

So 64 and 144 is the answer.

Answer:

[tex]\bold{y=1.5\times 2^x+4}[/tex]

Step-by-step explanation:

Equation for an exponential function is given as following:

[tex]y=ab^x+c[/tex]

Where b is the common ratio and  

c is the horizontal asymptote (y value)

a is the coefficient of exponential term of [tex]x[/tex]

[tex](x,y)[/tex] are the points on the function.

Here, we are given that:

Common ratio, b = 2

Horizontal asymptote at y, c = 4

So, the equation becomes (let us put the values of b and c):

[tex]y=a\times 2^x+4[/tex]

We need the value of a. Let us put value of (x,y) as (2,10).

[tex]10=a\times 2^2+4\\\Rightarrow a\times 4 =10-4 =6\\\Rightarrow a =\dfrac{6}{4} =\bold{1.5}[/tex]

So, the final equation of the exponential function is:

[tex]\bold{y=1.5\times 2^x+4}[/tex]

Answer:

1. The coordinates of the image you want to transform

2. The change in y

3. The change in x

Step-by-step explanation:

If we transform an image, we are moving it around the coordinate plane.

In order to transform, we need the original coordinates of the image so that we know where to start.

We also need to know the change in y because when we transform a shape it can go up and down.

We also need to know the change in x because when we transform a shape it can go left and right.
