65= t - 5 - 7 what is t
Nookie1986 [14]

Answer: t = 77

Step-by-step explanation:

    To solve for t, we will simplify and isolate the variable.

Given:

    65 = t - 5 - 7

Combine like terms:

    65 = t - 12

Add 12 to both sides of the equation:

    77 = t

PLEASE HELP!!!!<br><br> f(x)= {____for____<br> {____for____
hammer [34]

9514 1404 393

Answer:

  f(x)=\left\{\begin{array}{ccc}3&\text{for}&-5\le x < 0\\1-x&\text{for}&0

Step-by-step explanation:

The left section is defined at x = -5, but not at x = 0, so the interval for that definition is -5 ≤ x < 0. The function value on that interval is constant: 3.

The right section is defined a x = 5, but not at x = 0, so the interval for that definition is 0 < x ≤ 5. That section is a straight line with a slope of -1 and a y-intercept of 1. The function value on that interval can be written -x+1.

Then the piecewise definition is ...

  f(x) = {3, for -5 ≤ x < 0; -x+1, for 0 < x ≤ 5}

The surface area of a triangular pyramid is 1836 ft2.
Archy [21]
A triangular pyramid has 4 triangular faces. If all 4 have the same area, then one of them has area 1/4 of the surface area, 1836. That gives 459 sq ft as the area of one of the triangular faces.
