Find the area of this trapezoid. Be sure to include the correct unit in your answer.14 ft16 ft7 ft17 ft

goblinko [34]

The area of a trapezoid can be found through the formula

$A=\frac{a+b}{2}\cdot h$

where a and b are the bases and h the height, then,

$\begin{gathered} A=\frac{14+7}{2}ft\cdot7ft \\ A=10.5ft\cdot7ft \\ A=73.5ft^2 \end{gathered}$

Write the standard equation of the circle with center (-14, -3) that passes through the point (-5,3),

grin007 [14]

Answer:

$(x + 14)^2 + (y + 3)^2 = 117$

Step-by-step explanation:

Equation of a circle:

The equation of a circle with center $(x_0,y_0)$ is given by:

$(x - x_0)^2 + (y - y_0)^2 = r^2$

In which r is the radius.

Center (-14, -3)

This means that $x_0 = -14, y_0 = -3$

$(x - x_0)^2 + (y - y_0)^2 = r^2$

$(x - (-14))^2 + (y - (-3))^2 = r^2$

$(x + 14)^2 + (y + 3)^2 = r^2$

Passes through the point (-5,3),

This means that when $x = -5, y = 3$ . We use this to find the radius squared. So

$(x + 14)^2 + (y + 3)^2 = r^2$

$(-5 + 14)^2 + (3 + 3)^2 = r^2$

$r^2 = 117$

So, the equation of the circle is:

$(x + 14)^2 + (y + 3)^2 = r^2$

$(x + 14)^2 + (y + 3)^2 = 117$

Klaus was replacing the roof on his house. He used 420 nails to attach all the pieces of wood. Each piece of wood needed 7 nails

Sladkaya [172]

Answer:

Step-by-step explanation:

if 7 nails are required for each piece of wood, you must determine how much wood you have in total by dividing the amount of nails by 7.

If you have used 40 nails out of sixty, you 20 left because

60-40=20
