Answer:

It will take him 1 hour 35 minutes to finish a 10 mile race

Answer is (C)

Cody runs 10-mile in 1 hour 35 minutes.

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Given that;

Cody runs 4 miles in 38 minutes.

Now,

Since, Cody runs 4 miles in 38 minutes.

Hence, The time to run 10 miles = 38 × 10 / 4

                                                  = 380/4

                                                  = 95 minutes

                                                  = 1 hour 35 minutes

Thus, Cody runs 10-mile in 1 hour 35 minutes.

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

Explanation:

Of your original given list, let's write down the parallelograms. They are:

So we cross those off the list since we want a quadrilateral with no sides parallel. A parallelogram, by definition, is a quadrilateral with both pairs of opposite sides that are parallel.

We can also rule out the trapezoids because a trapezoid is a four sided figure (quadrilateral) where we have exactly 1 pair of parallel sides, while the other sides are not parallel.

Lastly, we can rule out the kite because any kite has perpendicular diagonals.

The only thing left is quadrilateral. In my opinion this answer should be more specific and say "quadrilateral that isn't a parallelogram, a trapezoid, or a kite", but I think I see what your teacher was going for here.

Answer:

4 weeks

Step-by-step explanation:

Step one:

ben has 72 followers on his first day.

He averages 10 new followers each week

let the number of weeks be x

and the total followers be y

y= 72+10x--------1

Sarah also started a Twitter account and

has 100 followers on her first day and averages

3 new followers each week

let the number of weeks be x

and the total followers be y

y= 100+3x--------2

Step two:

let us equate the two expression to get the number of weeks x

72+10x=100+3x

collect like terms

10x-3x=100-72

7x=28

divide both sides by 7

x=28/7

x= 4 weeks

Answer:

Each of the domain values, x, should only output a single unique range value, y.

This example is a relation and not a function because the the domain value of -1 output 2 distinct range values.

Step-by-step explanation:

The missing coefficients of x² is 8.

An expression is any mathematical statement which consists of numbers, variables and an arithmetic operation between them. In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

here, we have,

According to the question we have been given the expression which is :

(15x^2+11y^2+8x)-(7x^2+5y^2+2x)=[blank]x^2+6y^2+6x      

In this we have to find the missing coefficient.

To find the missing coefficients we will solve the L.H.S that is

=  (15x^2+11y^2+8x)-(7x^2+5y^2+2x)    

First we will eliminate the brackets we get

   15x^2+11y^2+8x-7x^2-5y^2-2x

Solving the coefficients of  x² terms , y² terms and x terms we get

       = 8x² + 6y² + 6x

Which is equal to the R.H.S

Combining both the equation we get the coefficient of the x² is 8.

Hence the missing coefficient is 8.

Step-by-step explanation:

The value of the expression given as  [3² * 3⁻⁵]/[5⁻²] is 25/27

The expression is given as:

3 squared times 3 to the power of negative 5 end quantity over 5 to the power of negative two

Rewrite properly as:

[3² * 3⁻⁵]/[5⁻²]

Apply the negative exponent law of indices

So, we have

[3² * 3⁻⁵]/[5⁻²] = [5²]/[3⁻² * 3⁵]

Apply the exponent law of indices

[3² * 3⁻⁵]/[5⁻²] = [5²]/[3³]

This gives

[3² * 3⁻⁵]/[5⁻²] = 25/27

Hence, the value of the expression given as  [3² * 3⁻⁵]/[5⁻²] is 25/27

Answer:

x = 8

Step-by-step explanation:

Since there are 3 x's in the graphic, we have to think what times 3 is 24? The answer to that is 8!

The value of x in the diagram is 8.

A tape diagram is a rectangular visual model that resembles a piece of tape, that is used to assist with the calculation of ratios and addition, subtraction, and commonly multiplication.

It is also known as a divided bar model, fraction strip, length model or strip diagram.

From the diagram, you will notice that:

x + x + x = 24

Add the three x:

3x = 24

Divide both sides by 3:

x = 24/3

x = 8

Thus, the value of x is 8.

Answer:

Step-by-step explanation:

You want an inequality to determine how many miles eddie can travel if he has $15 to spend on a taxicab that charges $1.75 for the flat fee and $0.25 for each mile.

The mileage charge is the per-mile charge ($0.25) multiplied by the number of miles (m). It will be $0.25m.

The total charge is the mileage charge plus the flat fee. Eddie wants that to be no greater than $15.

  1.75 +0.25m ≤ 15

We can solve this inequality in 2 steps.

  0.25m = 13.25 . . . . . subtract 1.75

  m = 53 . . . . . . . . . . . divide by 0.25 (or multiply by 4)

Eddie can travel 53 miles if he has $15 to spend.
