Since 11/10 is 1.1 you can add that to 22 and get 23.1. Then you can subtract 35 - 23.1 and get
11.9

For this case we must find the solution of the following equation:

$2x-1 = 3x + 2$

If we subtract 3x from both sides of the equation we have:

$2x-3x-1 = 2$

Different signs are subtracted and the major sign is placed

$-x-1 = 2$

We add 1 to both sides of the equation:

$-x=2+1\\-x=3$

We multiply by -1 on both sides of the equation:

$x = -3$

So, the solution is $x = -3$

Answer:

$x = -3$

The speed of cars passing through the intersection of Blossom Hill Road and the Almaden Expressway varies from 14 to 35 mph and

Ivan

Answer:

28.57% probability that the speed of a car is between 17 and 23 mph

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X between c and d is given by the following formula:

$P(c \leq X \leq d) = \frac{d - c}{b - a}$

14 to 35 mph and is uniformly distributed.

This means that $a = 14, b = 35$

What is the probability that the speed of a car is between 17 and 23 mph?

$P(c \leq X \leq d) = \frac{d - c}{b - a}$

$P(17 \leq X \leq 23) = \frac{23 - 17}{35 - 14} = 0.2857$

28.57% probability that the speed of a car is between 17 and 23 mph

The opening in a rectangular door frame measures 9 feet by 3 feet. Each of the four doors described in the table measures 9

Nataliya [291]

Answer:

Door 3 diagonal 3√10 feet

Step-by-step explanation:

The diagonal of a rectangle is the hypotenuse of a right triangle whose legs are the side lengths of the rectangle. That is, the diagonal of a 9 ft by 3 ft rectangle will have length ...

d = √(9² +3²) = √90 = 3√10

Any "9 ft by 3 ft" figure that has a diagonal different from this is not a rectangle. To fit the rectangular opening, we want a rectangular door—one with a diagonal of 3√10 feet.

In triangle ABC, BC=4 centimeters, m angle B=m angle c, and m angle a = 20 degrees. What is AC to two decimal places?

maks197457 [2]

Answer:

The correct answer AC = 11.52

Step-by-step explanation:

From the figure attached with this answer shows the triangle ABC.

BC=4 centimeters, m angle B=m angle c, and m angle a = 20 degrees

To find AC

From the figure we can see that D is the mid point and AD⊥BC

Then BD = CD = 4/2 = 2 cm

<BAD = 10° and <CAD = 10°

By using trigonometric ratio,

sin 10 = CD/AC = 2/AC

AC = 2/sin 10 = 2/0.1736 = 11.52

Therefore the value of AC = 11.52 cm
