Hey there!

A quadrilateral has 360 degrees. So add all the degrees together to 360. 9x+1+5x-12+8x+61+90=360. 90 degrees is in the bottom left corner. Combine like terms. 22x+140=360. Subtract 140 from each side. 22x=220. Divide 22 on each side to get x=10. Plug in 10 for x in angle D. 5(10)-12=38. The measure of angle D is 38 degrees.

I hope this helps!

the food pantry distribution 10 oz bags of rice if 3 5 lb bags are donated to the pantry how many 10 ounce bags can be made ​
dolphi86 [110]

Answer:

24 bags can be made from three 5 pounds bags.

Step-by-step explanation:

Given that:

Three 5 pound bags are donated.

Total weight of bags = 3*5 = 15 pounds

We know that:

1 pound = 16 ounces

15 pounds = 16*15 = 240 ounces

A bag weighs 10 ounces.

Number of bags = \frac{240}{10}

Number of bags = 24 bags

Hence,

24 bags can be made from three 5 pounds bags.

"Find the value of the derivative (if it exists) at each indicated extremum. (If an answer does not exist, enter DNE.) f (x) = c
Oliga [24]
\bf f(x)=cos\left( \frac{\pi x}{2} \right)\implies \cfrac{df}{dx}=\stackrel{chain~rule}{-sin\left( \frac{\pi x}{2} \right)\cdot \frac{\pi }{2}}

now, what is the value of the derivative at any extrema on the original function?  well, by definition, if the original function has an extrema anywhere, the derivative will be the derivative of a horizontal tangent line to it, and by definition it'll be 0.

4(x-7)=2x-6 (show work)
irina [24]

Answer:

x = 11

Step-by-step explanation:

Given

4(x - 7) = 2x - 6 ← distribute parenthesis on left side

4x - 28 = 2x - 6 ( subtract 2x from both sides )

2x - 28 = - 6 ( add 28 to both sides )

2x = 22 ( divide both sides by 2 )

x = 11
