Answer:

  A) r = d/t

  B) 221,760 ft/h

  C) 42 mi/h

  D) miles; the number is more comprehensible

Step-by-step explanation:

A) Given d = rt

Divide by the coefficient of r to solve for r.

  r = d/t

__

B) Fill in the given numbers to find the rate in ft/h.

  r = (665,280 ft)/(3 h) = 221.760 ft/h

__

C) Multiply by the conversion factor (1 mi)/(5280 ft) to convert to miles.

  (221,760 ft/h)(1 mi)/(5280 ft) = 42 mi/h

__

D) For this scenario, miles per hour is a better unit for speed. Many people have seen that speed registered on a speedometer, so have some sense of what it means. Often numbers outside the range of 1 to 1000 are beyond ready comprehension.

Answer:

You can use 0.60 × 90, 3 × 18 works as well.

Step-by-step explanation:

Hmmm....let's see.

You can use 0.60 × 90, 3 × 18 works as well. The answer is 54.

We know this because when finding a percentage of a number you multiply that decimal by the number. 2nd option as well as last option could work. Hope this helps, please mark brainliest!

Answer:

C =(x-3)(x-2)/x

or

x²-5x+6/x

Step-by-step explanation:

2x^2 - 4x - 6/x + 2 * x^2 - 4/2x^2 + 2x

Factorizing the given factors

1) 2x^2 - 4x - 6

= 2x^2 - 6x+2x - 6

= 2x(x-3) +2(x-3)

= (x-3)(2x+2)

2) x^2 - 4

= (x+2) (x-2)

3) 2x^2 + 2x

= 2x( x+1)

Putting the factors

(x-3)(2x+2)/x + 2   *  (x+2) (x-2)/2x( x+1)

= (x-3)(2x+2) (x-2)/2x( x+1)

= 2(x-3)(x+1) (x-2)/2x( x+1)

=(x-3)(x-2)/x

Now multiply

(x-3)(x-2) =x²-5x+6

Then the answer becomes  x²-5x+6/x

Answer:

x = 5.25

Step-by-step explanation:

Solve by substitution by substituting 2x as y into the first equation:

1/2(2x + y) = 21/2

1/2(2x + 2x) = 21/2

Simplify and solve for x:

1/2(4x) = 21/2

2x = 21/2

x = 21/4

x = 5.25

So, x = 5.25

Answer:

x = 5.25

step- by - step explanation

1/2 × ( 2x + y ) = 21/2 .............( 1 )

y = 2x ......................( 2 )

substitute the value of y in ( 1 )

1/2 ( 2x + 2 x ) = 21/2

simplify

1/2 ( 2 x + 2 x ) = 21/2

combine like terms

1/2 ( 4x ) = 22/2

Divide the numbers

1/2 ( 4 x ) = 10.5

divide 4 x by 2

4 x / 2 = 10.5

2 x = 10.5

divide each side by 2

2x/2 = 10.5 / 2

x = 5.25

Answer and Step-by-step explanation:

i^1 = i, i^2 = -1, i^3 = -i, i^4 = 1

Since we know this, we can go to the last instance of the multiply of 4.

For this question, it is 12. 2 more after twelve is 14. Since it is 2, it would be -1.

D. -1 -- This is the answer.

Step-by-step explanation:

2600(.95)^5

if its going down by 5 percent, we minus 5 from 100 and put it in decimal form. any decimal lower than 1.00 will result in a lower number. for 5 years, we place 5 as an exponent

uh sorry if that doesn't make a lot of sense

Answer:

Rectangular prisms are six-sided polygons; three-dimensional shapes of which all sides meet at 90-degree angles, like a box. Cubes are a special type of rectangular prism of which all sides are the same length; this is the key difference between cubes and other rectangular prisms.

Answer:

option on c or under the first answer

C option number line models the expression -1 1/4 - (-1/2)

A number line can be defined as a straight line with numbers placed at equal intervals or segments along its length.

The numbers on the number line increase as one moves from left to right and decrease on moving from right to left.

According to question the given expression is  -1 1/4 - (-1/2)

On solving  -1 1/4 = -5/4 or -1.25

and we can write (-1/2) as -0.5

so the expression is simplified to -1.25 - (-0.5) = -0.75

Thus the correct option is "C"

Answer:

-32..............

......

Answer:

-32.

Step-by-step explanation:

This is basically the same thing as multiplying -2 5 times (-2x-2x-2x-2x-2), and you get -32.

Both operations in the equation are adding so you would add the numbers from left to right.

The first step would be 33 + 46

Answer: 1. 33 + 46

Answer:

y= 3x+4

Step-by-step explanation:

2y-6x=8

add 6x to each side

2y-6x+6x=6x+8

2y= 6x+8

divide each side by 2

2y/2 = 6x/2 + 8/2

y= 3x+4

Answer:

y = 3x+4

Step-by-step explanation:

2y-6x=8

We want to solve for y

Add 6x to each side

2y-6x+6x=6x+8

2y = 6x+8

Divide each side by 2

2y/2 = 6x/2 +8/2

y = 3x+4

Answer:

56 cm^2

Step-by-step explanation:

Surface area is just finding the areas of each face in a figure. As we are given a net of a figure, it is much easier for us to calculate it.

Area of square base (side^2)

4^2 = 16 cm^2

Area of ONE triangular face (1/2 x b x h):

1/2 x 4 x 5 = 10 cm^2

Multiply that by 4 because we have 4 triangular faces: 10 cm^2 x 4 = 40 cm^2

ADD all the areas of triangles and square:

16 cm^2 + 40 cm^2 = 56 cm^2

HOPE THIS HELPS

Given:

The lengths, in inches, of each fish are listed:

9, 13, 9, 21, 18

To find:

The statement that best represents the meaning of the range for these data.

Solution:

The given data values are:

9, 13, 9, 21, 18

Arrange the data values in ascending order.

9, 9, 13, 18, 21

Here, the maximum value is 21 and the minimum value is 9.

We know that,

[tex]\text{Range}=\text{Maximum value}-\text{Minimum value}[/tex]

[tex]\text{Range}=21-9[/tex]

[tex]\text{Range}=12[/tex]

The range of the data set is 12. Therefore, the difference between the shortest and longest fish is 12 inches.

Answer:

Step-by-step explanation:

First, the numbers should be in ascending or descending order . Since, 4 numbers are in ascending order we don't have to do that .

Second, find the "middlest" of them . If there were total of odd numbers it would have been easier but, here is total of even number(4) and mean of 2 middlest number would be its median: (4+4)/2=4 .
