(d) Jim walks three miles in 45 minutes. How long does it take for him to walk 5 miles?​
kramer

Answer:

  • 5 miles = 75 minutes

Step-by-step explanation:

<u>We know that:</u>

  • 3 miles = 45 minutes

<u>Solution:</u>

  • 3 miles = 45 minutes
  • => 1 mile = 45/3 minutes
  • => 5 miles = 45/3 x 5
  • => 5 miles = 15 x 5
  • => 5 miles = 75 minutes

Hence, it takes 75 minutes for Jim to walk 5 miles.

Vladimir says that the equation of the line that passes through points (negative 5, negative 3) and (10, 9) is y = four-fifths x
love history [14]

Answer:

Vladimir and Robyn both are correct.

Step-by-step explanation:

Let us check whether the points (-5,-3) and (10,9) are on the line y = \frac{4}{5}x + 1 or not.

The equation of the straight line passing through the given points (-5,-3) ans (10,9) is \frac{y - 9}{9 + 3} = \frac{x - 10}{10 + 5}

⇒ 5(y - 9) = 4(x - 10)

⇒ 5y = 4x + 5

⇒  y = \frac{4}{5}x + 1 .............. (1)

So, Vladimir is correct.

Now, Robyn says that the line passes through the points (-10,-7) and (-15,-11).

Then, both of the points satisfy the equation (1).

Therefore, Vladimir and Robyn both are correct. (Answer)

The function f(x)= -6x+11 has a range given by {-37,-25,-13,-1}.Select the domain values of the function from the list 1,2,3,4,5
andreev551 [17]
The range is {-37,-25,-13,-1}. So you need to figure out what four numbers from this list of numbers (1,2,3,4,5,6,7,8), when applied to this
function, ( f(x)=-6x+11 ), equals these numbers that are in the range {-37,-25,-13,-1}.

So you apply each of these numbers (1,2,3,4,5,6,7,8) into the function (f(x)=-6x+11)
one by one.

f(1)=-6(1)+11=5
f(2)=-6(2)+11= -1
f(3)=-6(3)+11= -7
f(4)=-6(4)+11= -13
f(5)=-6(5)+11= -19
f(6)=-6(6)+11= -25
f(7)=-6(7)+11= -31
f(8)=-6(8)+11= -37
As you can see, f(2),f(4),f(6),and f(8) equal the numbers that are in the range {-37,-25,-13,-1}.

A company produces birthday cards and get well cards at a ratio of 6 to 5 how many birthday cards can ve expected if 60 get well
Alik [6]

The number of birthday cards made is 72.

<h3>Description of ratios</h3>

Ratio expresses the relationship between two numbers. It shows the frequency of the number of times that one value is contained in another number. The sign used to represent ratios is :

<h3>Determining the total cards made. </h3>

Total card = (sum of ratios x number of get well cards) / ratio of get well cards

(11 x 60) / 5 = 132

<h3>Number of birthday cards made </h3>

6/11 x 132 = 72 cards
