Write the radio 5:15 in a percentage

Answer:

Restrict values of  x  to .  Then the surface area function is one-to-one and has an inverse.

Write  y  instead of S(x).  Interchange  x  and  y, then solve for  y.

This function could be used to find the edge of a cube with a given surface area.  For example, if the area is  x = 54, then the edge is

Answer:

A(7,4)

Step-by-step explanation:

-2/3 is the slope and the slope is the rise over the run, and we know it passes through the point (1,8).

Next, we can create a chart/table

X int-1+3=4, 4+3=7

Y int-8-2=6,6-2=4

1st point: (4,6)

2nd point: (7,4)

Hope I helped, have a nice day :)

Answer:

90 mph

Step-by-step explanation:

To get miles per hour ([tex]m/h[/tex]), we just need to divide. [tex]360/4[/tex] gives us [tex]90/1[/tex], meaning the train travelled 90 miles in one hour. This is the same as going 90 mph. Hope that explained things :)

Answer:

x = 52

Step-by-step explanation:

An isosceles triangle is a triangle with two congruent sides, meaning two sides have the same measure. One property of an isosceles triangle is the base angles theorm. This theorem states that the angles opposite the congruent sides in an isosceles triangle are cognruent. Applying this theorem to the given triangle, one can state the following:

52 = x

Answer:

I think the answer is 52 so x=52

Answer:

x=3

Step-by-step explanation:

15/x=10/2

Simplifying the right side

15/x = 5

Multiply each side by x

15/x *x = 5x

15 = 5x

Divide each side by 5

15/5 = 5x/5

3 =x

Answer:

2/7 and 7/5

Step-by-step explanation:

Answer:

  (x, y) = (12, -12)

Step-by-step explanation:

The two equations can be added to solve for x.

  (-5x -5y) +(6x +5y) = (0) +(12)

  x = 12 . . . . . . . . simplify

  -5(12) -5(y) = 0 . . . substitute into the first equation

  12 +y = 0 . . . . . . . divide by -5

  y = -12 . . . . . . . . subtract 12

The solution is (x, y) = (12, -12).

Answer:

[tex]a_{n}[/tex] = - 3n - 3

Step-by-step explanation:

The nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 6 and d = a₂ - a₁ = - 9 - (- 6) = - 9 + 6 = - 3 , then

[tex]a_{n}[/tex] = - 6 - 3(n - 1) = - 6 - 3n + 3 = - 3n - 3

Answer:

2 degrees / hour

Step-by-step explanation:

The average rate of change is

f(x2) - f(x1)

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

x2 -x1

We know that x2 is 6pm so f(x2) is 101

We know that x1 is 10 am so f(x1) is 85

101 -85

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

6 pm - 10 am

16 degrees

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

8 hours

2 degrees / hour

Answer:

We have this proportion....

36 / 12 = x / 9 where x is the model door height

Cross-multiply

36*9 = 12 * x

324 = 12 *x divide both sides by 12

27 = x and that's the model height in centimeters

Answer:

Each slice of bread costs $0.06.

Step-by-step explanation:

To find how much each slice of bread costs, you need to divide the cost (0.90) by how many slices there are (15). When you divide the two, you get 0.06. To check your answer you can do 0.06x15 and that will equal $0.90.

Answer:

0.9/15=$0.06 per slice

Also what is this 1910 when did a loaf of bread cost 90 cents????

Answer:

47yd

Answer:

x = 9

Step-by-step explanation:

These are alternate exterior angles and alternate exterior angles are equal if m is parallel to n

6x+5 = 7x-4

Subtract 6x from each side

6x -6x+5 = 7x-6x-4

5 = x -4

Add 4 to each side

5+4 =x-4+4

9 =x

Answer:

103 chairs

Step-by-step explanation:

cost = fee + cost per chair * number of chairs

410 = 100 + 3*c

Subtract 100 from each side

410-100 = 100+3c-100

310 = 3c

Divide by 3

310/3 = 3c/3

103.3=c

We cannot rent part of a chair so we round down

103 chairs

6x+4y=16

<=> -y=-1

2x+y=5

<=> y=1

2x+1=5

<=> y=1

2x=4

<=> y=1

Answer:

t=6

Step-by-step explanation:

h(t) = -16t^2 +64t + 192

We want h(t) =0

0 = -16t^2 +64t + 192

Factor out -16

0 = -16 (t^2 -4t -12)

Factor.  What terms multiply to -12 and add to -4   -6*2 = -12  -6+2 = -4

0 = -16(t-6)(t+2)

Using the zero product property

0=t+2     0=t-6

t = -2   t=6

But t=-2 happens before the event occurs   so the solution is t=6
