Answer:

  1872

Step-by-step explanation:

Solving cryptarithm sums requires consideration of the properties of numbers, addition facts in particular.

The largest possible value of F is 1. For that value, there are no choices for RUN that allow A to be 9, so its maximum value is 8. In order for A to be 8, R must be 9, so the largest digit available for S is 7, which requires U = 3. In order for S to be odd, N must be 5 or greater. The largest available digit is 6.

This gives RUN = 936; FAST = 1872.

_____

<em>Additional comment</em>

This is confirmed (suggested) by an exhaustive search. The <em>least</em> possible sum is RUN = 523; FAST = 1046.

A student solved the equation sin2x/cosx=2, 0&lt;=x&lt;=pi and found the answer of pi/2 describe the students error
finlep [7]
For the given equation ⇒⇒⇒ \frac{sin \  2x}{cos \ x} =2
and the given range 0 ≤ x ≤ π
We should note that the zeros of the denominator will be at 
cos x = 0
∴ x =  cos^{-1} 0 =  \frac{\pi}{2}
So, the given equation is undefined at π/2
So, <span>the students error is the division by zero.
</span>

See the attached figure which represents the graph of the given equation and we can see it is undefined at π/2

Answer:

Angle 1 and Angle 5. Option 3 or C.

Step-by-step explanation:

Corresponding angles are formed when a transversal passes through two lines.

So..

Angle 1 and 5 are corresponding.

More help:

Corresponding angle meaning: the angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal.

this will help you find them in the future!

Hope this helps!

Rod is paid $85 to install a screen door and $115 to install a wooden door. In one week he installed 18 doors and was paid a tot
Rainbow [258]

Answer:Rod installed  7 screen doors

Step-by-step explanation:

Step 1

Let the number of screen door = x

And the number of wooden doors = y

since he installed 18 doors , we have that

screen door + wooden doors = 18

x + y = 18------ equation 1

Also the cost to install a screen  door -= $85

and to install a wooden door = $115

And he was therefore paid a total of $1850

Therefore

85x + 115 y = $1860------- equation 2

Step 2----- Solving

x + y = 18------ equation 1

85x + 115 y = $1860------- equation 2

Multiplying equation 1 BY 85

85x + 85y= 1530------- equation 3

85x + 115 y = $1860------- equation 4

subtracting from equation 1 from (2)

115y- 85y= 1860-1530

30y=330

y = 330/30 = 11

To find x

x+ y=18

x= 18-y

x= 18-11= 7

Rod installed  7 screen doors and 11 wooden doors.
