Answer:

Option B. False

Step-by-step explanation:

Here three segments have been given of length of 8, 7, 15 and we have to tell whether a triangle will be formed or not.

Since we know a triangle is only possible when sum of two sides is greater than the third side.

That means in the segments A,B,C

(A+B) > C ⇒ (8+15) > 7

(B+C) > A ⇒ (15+7) > 8

(A+C) > B ⇒ (8+7) not greater than 15

Therefore Option B. False is the answer.

False because 7+8=15. The two sides need to add up to more then the hypotenuse

What is the coordinate of point P on the line segment AB that is 3/4 of the distance from A to B for A(2,5) and B(6,9)?

Brut [27]

Answer:

p is (3.71, 6.71)

Step-by-step explanation:

Given that p is at the distance of 3/4 from A to B

it mean that point p divides the line AB into 3:4 ratio.

and

if there are two points (x1,y1) and (x2,y22) which is divided by point p in the ratio m:n then

coordinates of point p (x,y) is given

p (x = (n*x1+m*x2)/m+n , y = (n*y1+m*y2)/m+n )

________________________________________________

Given the points AB

A(2,5)

B(6,9)

m:n = 3:4

thus,

p (x = (4*2+3*6)/7 , y = (4*5+3*9)/7 )

p (x = (26/7 , y = 47/7 )

P ( x = 3.71, y = 6.71)

Thus, coordinates of point p is (3.71, 6.71) which is at 3/4 of the distance from A to B for A(2,5) and B(6,9)/

A trapezoid has a perimeter of 14 feet. What will the perimeter be if each side length is increased by a factor 7? 21 feet 98 fe

natka813 [3]

Answer:

Correct choice is B

Step-by-step explanation:

Let a, b, c and d be the trapezoid's sides lengths.

The perimeter of the trapezoid is the sum of all sides lengths, thus,

$a+b+c+d=14\ ft.$

If each side length is increased by a factor 7, then new sides have lengths 7a, 7b, 7c and 7d. The perimeter of new trapezoid is

$7a+7b+7c+7d.$

Use the distributive property for this expression:

$7a+7b+7c+7d=7(a+b+c+d).$

Since $a+b+c+d=14\ ft,$ then

$7a+7b+7c+7d=7(a+b+c+d)=7\cdot 14=98\ ft.$
