1. Diameter= 14-2-2 = 10 feet

2. 11x 14 = 154

1/2 x 3.14 x 5^2 = 39.25

Area = 154-39.25 = 114.75 square feet

3. 114.75 x 1.50 = $172.13

4b+3=−9 i need help it is inportant

Fantom [35]

Answer:

b=-3

Step-by-step explanation:

4b+3=-9

-3 -3

subtract 3 from both sides like so. 3-3 cancels out. -9-3=-12.

4b=-12

youre left with 4b=12 so DIVIDE 4b by 4 and -12 by 4

4b/4=-12/4

4b divided by 4 is 1. -12 divided by 4 is -3

b=-3

plug -3 in for b to make sure its correct

4(-3)+3=-9

-12+3=-9

-9=-9

Step-by-step explanation:

Solve for y in the first equation.

$y=\frac{4}{3}$ , replace y with $\frac{4}{3}$

Solve for in the first equation.

$x = \frac{8}{3}, y = \frac{4}{3}$

Help me please. Find the measures of CAD and DAE

VladimirAG [237]

well, we know the "sum" of both angles is 90°, notice the rectangle in the corner, so we can say that the angles are simply complementary angles, thus

$\left( \cfrac{3}{2}x+20 \right)+2x=90\implies \stackrel{\textit{multiplying both sides by }\stackrel{LCD}{2}}{2\left( \cfrac{3}{2}x+20 + 2x \right)=2(90)} \\\\\\ 3x+40+4x=180\implies 7x+40=180\implies 7x=140\implies x=\cfrac{140}{7} \\\\\\ x = 20~\hfill \stackrel{\measuredangle CAD}{\cfrac{3}{2}20+20\implies 50}\qquad\qquad \stackrel{\measuredangle DAE}{2(20)\implies 40}$
