Answer:

-1/2 is your answer.

Step-by-step explanation:

The slope formula is (y_2 - y_1)/(x_2 - x_1)

The y's are -3 and 2, while the x's are 9 and -1.

(-3-2)/(9-(-1))=-5/10=

-1/2 is your answer.

Find the value of x. If necessary, round to the nearest tenth A= 49 sq. In

Romashka-Z-Leto [24]

Answer:

Step-by-step explanation:

Alright, lets get started.

Area is given as 49 square inches.

The formula for area A = $\frac{1}{2}*base*height$

base is given as x

Height is given as x

Hence area is A

A = $\frac{1}{2}*x*x = 49$

Multiplying 2 in both sides

$x^2=98$

Taking square root on both sides

$x=9.9$

hence the answer is x = 9.9 in : Answer

Hope it will help :)

Answer:

Option A - Permutation; number of ways = 210

Step-by-step explanation:

Given : At a competition with 7 runners, medals are awarded for first, second, and third places. Each of the 3 medals is different.

To find : How many ways are there to award the medals?

Solution :

There are 7 runners but medals are three.

The first runner up got first medal as one is locked.

The second runner up got second medal as second is locked.

The third runner up got the third medal.

So, There is a permutation.

Number of ways to award the medals is $^7P_3$

We know, $^nP_r=\frac{n!}{(n-r)!}$

Substitute the values,

$^7P_3=\frac{7!}{(7-3)!}$

$^7P_3=\frac{7\times 6\times 5\times 4!}{4!}$

$^7P_3=210$

Therefore, Option A is correct.

Permutation; number of ways = 210
