The area of a triangular block is 16 squre inches. If the base of the triangle is twice the height, how long are the base and th

klemol [59]

The area of a triangle can be calculated using the formula

1/2 (base) (height)

Let's substitute our known values, letting x represent the value of the height of the triangle.

16 = 1/2* x* 2x

Let's Simplify!

16 = x^2

Finally, lets take the square root of both sides, to get rid of the exponent on the right side of the equation.

x= positive OR negative 4.

However, because x is equal to the height, we know that it can't be negative, so we know that it is positive 4.

The height of the triangle = 4 inches
The base of the triangle = 2h = 8 inches

Last question of my homework pls <3

dimaraw [331]

Answer:

J(2, 5 )

Step-by-step explanation:

Using the section formula

$x_{J}$ = $\frac{1(-2)+2(4)}{2+1}$ = $\frac{-2+8}{3}$ = $\frac{6}{3}$ = 2

$y_{J}$ = $\frac{1(1)+2(7)}{2+1}$ = $\frac{1+14}{3}$ = $\frac{15}{3}$ = 5

Thus J = (2, 5 )

P is the set of natural numbers that are less than 12

Damm [24]

Answer:

{ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 }

Step-by-step explanation:

As per the definition, a natural number is a counting number (non-fractional number) that is greater than zero, but not equal to zero.

A set of natural numbers below 12 (but not including 12, because such isn't specified) would henceforth be;

{ 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 }
