7 0

Answer:

Correct me if I'm wrong, but I'm pretty sure it is 7.

Step-by-step explanation:

because to find area you multiply length * width so 10 times 7 is 70?

5n + 34 = -2 ( 1 - 7n) this is due by midnight. NO LINKS PLEASE!

kodGreya [7K]

Answer :

n = 4

Step-by-step explanation:

5n + 34 = -2(1-7n)

first distribute

5n + 34 = -2(1) -2(-7n)

5n + 34 = -2+14n

-5n

then get all of n to the same side

36 = 9n

isolate the variable

36/9 = 9n/9

4 = n

Answer:

Probability ≈ 0.1071

Step-by-step explanation:

Consider steps below;

$Total Possible Outcomes - 8C5,\\\\8! / 5! ( 8 - 5 )!,\\1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 / ( 1 * 2 * 3 * 4 * 5 )( 1 * 2 * 3 ),\\\\6 * 7 * 8 / 6 = Combinations - 56,\\\\$

$Number Of Outcomes - 6C5,\\\\6! / 5! ( 6 - 5 )!,\\1 * 2 * 3 * 4 * 5 * 6 / ( 1 * 2 * 3 * 4 * 5 ) ( 1 ),\\720 / 120 * 1,\\\\Outcomes - 6$

$Conclusion ; Solution - 6 / 56 = ( About ) 0.1071\\Hope That Helps!$

Solution; Probability ≈ 0.1071

A car traveling east at 40.0 m/s passes a trooper hiding at the roadside. The driver uniformly reduces his speed to 25.0 m/s in

Anni [7]

Step-by-step explanation:

It is given that,

Initial speed of the car, u = 40 m/s

Final speed of the car, v = 25 m/s

Time taken, t = 3.5 s

(a) We need to find the magnitude and direction of the car’s acceleration as it slows down. It can be calculated using formula as :

$a=\dfrac{v-u}{t}$

$a=\dfrac{25-40}{3.5}$

$a=-4.28\ m/s^2$

The acceleration is in the opposite direction of motion i.e. west.

(b) Let s is the distance the car travel in the 3.5-s time period. It can be calculated using the third equation of motion as

$s=\dfrac{v^2-u^2}{2a}$

$s=\dfrac{25^2-40^2}{2\times (-4.28)}$

s = 113.9 meters

Hence, this is the required solution.

The sum of two consecutive odd integers is 28. What are the integers?

Fantom [35]

The correct option is B): "Let x = 1st integer. Let x + 2 = 2nd integer."
Given that "The sum of two consecutive odd integers is 28."

Now the difference between two odd numbers is 2. So this means that one odd number has to be greater than the other by 2.

Let the smaller number be 'X' therefore the bigger number will be 'x+2' thus x + (x+2) = 28

therefore, x + x + 2 = 28 now we subtract "2" from both the sides
therefore, 2x = 26 now dividing throughout by 2 we get:

x = 13 therefore, x + 2 = 13+2
= 15

therefore, the numbers are 13 AND 15
