Bike sprockets and chain.

Which of the following gear ratios will have the highest overall speed?


2.26

2.87

3.5

4.63

Answer:

16 units squared

Step-by-step explanation:

First, calculate the distance between (0, 0) and (0, 4). The distance is in y, so there are 4 units in-between.

Next, calculate the distance between (0, 0) and (4, 0). This time, the distance is in x, but it is still four.

We know the dimensions of the shape are 4x4 so we just multiply.

4*4=16

Answer:

Image result for Three vertices of a rectangle are (6,1), (3,1), and (3,8). What are the coordinates of the fourth vertex?

One would be to divide the rectangle into two triangles, then use the Pythagorean Theorem to find the distances between the points, and finally use Heron's formula to find the areas of the two triangles.

To find the area of a triangle where you know the x and y coordinates of the three vertices, you'll need to use the coordinate geometry formula: area = the absolute value of Ax(By - Cy) + Bx(Cy - Ay) + Cx(Ay - By) divided by 2.

You need a place holder in both the dividend and the divisor when dividing polynomials.

Answer:

Four of those parts will have 144 degrees

Explanation:

                          A full circle will always have 360 degree

If the circle is divided into 10 equal parts,

The angle shall divide in 10 parts:

Each slice angle: [tex]\frac{360}{10}[/tex] = 36 degrees.

1 parts has 36 degrees; so:

Four parts will have: 36 * 4 = 144 degrees.

Answer:

930 feet

Step-by-step explanation:

[tex]=310yards\\\\=310yards*3\\\\=930feet[/tex]

Note that to convert the yards into feet we must multiply the value by 3.

Answer:

930 feet

Step-by-step explanation:

There are 3 feet in 1 yard. It is given to you to convert 310 yards into feet. Since 3 feet = 1 yard, simply multiply 3 with the given yards to obtain the feets:

310 yards x (3 feet/1 yard) = 930 feet/310 yards.

930 feet is your answer.

Answer:

  5.  x = 7

  6.  x = 13; YZ = 28

Step-by-step explanation:

It can help to start by writing the similarity statement for each figure. To do that, you can identify corresponding features, then work around the figure in a direction that maintains the correspondence of the vertices. Here the figures are dilated, and problem 5 has the figure rotated. Since there is no reflection involved, the corresponding vertices remain in clockwise order.

Once you have written the similarity statement, you can identify the values given for corresponding parts. Here, the values are all for side lengths (not angles). Corresponding sides will have their vertices in the same relative position in the similarity statement.

Working counterclockwise from the acute angle, we have ...

  KNML ~ PSRQ

Then corresponding sides are ...

  KN = 7x -9 . . . . PS = 60

  NM = not given . . . . SR = not given

  ML = 4x +4 . . . . RQ = 48

  LK = not given . . . . QP = not given

Now, you can write a proportion that involves corresponding sides. The main point here is to put corresponding parts in the same relative locations in the proportion. We can write this a couple of ways:

  KN/ML = PS/RQ   ⇔   (7x -9)/(4x +4) = 60/48

or

  KN/PS = ML/RQ   ⇔   (7x -9)/60 = (4x +4)/48

We note here that solution is generally easier if the variable is put in the numerator of the expression. We might choose the latter form for that reason. We might choose the first form because we know we can reduce the fraction 60/48 to 5/4, simplifying the problem a bit.

Using the second form of the proportion, we can solve it as follows:

  (7x -9)/60 = (4x +4)/48

  4(7x -9) = 5(4x +4) . . . . . . multiply by the LCM of 60 and 48, which is 240

  28x -36 = 20x +20 . . . . . eliminate parentheses

  8x = 56 . . . . . . . . . . . add 36-20x to both sides

  x = 7 . . . . . . . . . divide by 8

__

Counterclockwise from S, the similarity statement can be written ...

  ΔSYZ ~ ΔSRT

Corresponding parts are ...

  SY = not given . . . . SR = not given

  YZ = 2x +2 . . . . RT = 3x -7

  ZS = 40-5 = 35 . . . . TS = 40

A suitable proportion is ...

  (2x +2)/35 = (3x -7)/40

  8(2x +2) = 7(3x -7) . . . . . . . . multiply by 280

  16x +16 = 21x -49 . . . . . . eliminate parentheses

  65 = 5x . . . . . . . . . add 49-16x to both sides

  x = 13 . . . . . . . divide by 5

  YZ = 2x +2 = 2(13) +2

  YZ = 28

x = 56.5 and rounded to the nearest tenth is still gonna be 56.5 but to the nearest TENS is 60 (Please give brainliest!!)

Step-by-step explanation:

His is a right triangle so you can use SOH CAH TOA :

Sine = opposite/ hypotenuse

Cosine= adjacent/ hypotenuse

Tangent = opposite/ adjacent

here you have the hypotenuse and are looking to solve for the adjacent side to angle measure 28

so you can set this up like this: cos(28)= x/64

now multiply both sides by 64 and you'll get x = 56.5 just make sure your calculator is in degrees not radians

Step-by-step explanation:

Answer:

Equation 1:  8x + 10y = 123.4

Equation 2:  5x + 9y = 97.2

cost of a burrito = $7.30

cost of a sandwich = $6.30

Step-by-step explanation:

Let x = cost of a sandwich

Let y = cost of a burrito

Equation 1:  8x + 10y = 123.4

Equation 2:  5x + 9y = 97.2

Rewrite equation 1 to make y the subject, then substitute into equation 2 and solve for x:

8x + 10y = 123.4

⇒ 10y = 123.4 - 8x

⇒ y = 12.34 - 0.8x

5x + 9(12.34 - 0.8x) = 97.2

⇒ 5x + 111.06 - 7.2x = 97.2

⇒ 13.86 = 2.2x

⇒ x = 6.3

So cost of a sandwich = $6.30

Substituting x = 6.3 into equation 2 and solving for y:

5(6.3) + 9y = 97.2

⇒ 31.5 + 9y = 97.2

⇒ 9y = 65.7

⇒ y = 7.3

So cost of a burrito = $7.30

Answer:

8x + 10y = 123.40

5x + 9y = 97.20

OR

40x + 50y = 617

-40x - 72y = -777.6

x = $6.30

y = $7.30

Step-by-step explanation:

we can write this system of equations:

8x + 10y = 123.40

5x + 9y = 97.20

using the 'elimination method', we can multiply the first equation by 5 and the second equation by -8 to get:

5(8x + 10y) = 123.4(5)

40x + 50y = 617

-8(5x + 9y) = 97.2(-8)

-40x - 72y = -777.6

now we can add the new equations and solve for 'y':

40x + 50y = 617

-40x - 72y = -777.6

-22y = -160.6

y = 7.30

now we can substitute 7.3 for 'y' so we can solve for 'x':

8x + 10(7.3) = 123.4

8x + 73 = 123.4

8x = 50.4

x = 6.30

Answer:

x = 2 , y = -3

Step-by-step explanation:

by elimination method

+5y in equation 1 cancel -5y in equation 2

2x - 8x = -11 - 1

-6x = -12

divide both sides by - 6

- 6x/ -6 = -12/-6

x = 2

substitute x = 2 into equation ii

- 8 (2) - 5y = - 1

- 16 - 5y = - 1

collect like terms

- 5y = -1 + 16

- 5y = 15

divide both sides by -5y

-5y/-5y = 15/-5y

y = - 3
