Angle CMW and angle WML together form angle CML. Angle CMW is a right angle. What must be true about angle CML?

1 answer:

3 0

CML must be an obtuse angle.

Since CMW and WML together form CML, and CMW is a right angle, then CML must be larger than a right angle, which makes it obtuse.

Rus_ich [418]

35+5t=amount in tank A after t minutes
100-8t=amount in tank B after t minutes

same amount

35+5t=100-8t
add 8t both sides
35+13t=100
minus 35 both sides
13t=65
divide by 13 both sides
t=5

Anyone know the answer?

Alborosie

Step-by-step explanation:

${9}^{ \frac{ - 1}{2} } \\ {3}^{2 \times - \frac{1}{2} } \\ {3}^{ - 1} \\ \frac{1}{3}$

Now for another

${27}^{ \frac{ - 2}{3} } \\ {3}^{3 \times \frac{ - 2}{3} } \\ {3}^{ - 2} \\ \frac{1}{9}$

Hope it will help :)❤

The sides of a square field are 32 meters. A sprinkler in the center of the field sprays a circular area with a diameter that co

olga2289 [7]

You find the area not touched by the sprinkler by subtracting the area of the circle from the area of the square. The area of the square is 32*32 which is 1024. The area of the circle is found by multiplying 3.14 by the radius squared. Our radius is half the diameter of 32, so r = 16. A=3.14(16)(16) which gives us an area of the circle to be 803.84. Subtracting the 2 areas, square minus circle, is 1024-803.84=220.16 meters squared.

Marcos purchased a sail boat for $56,900. He anticipates each year the boat will decrease in value by 8.1% from the previous yea

Varvara68 [4.7K]

Answer: $56,900\left( 0.919\right)^x$

Step-by-step explanation:

Given

Marcos purchased a sailboat for $\$56,900$

Each year the boat will decrease in value by $8.1\%$

After 1 year it is

$\Rightarrow 56,900-56,900\times 0.081\\\Rightarrow 56,900\left( 1-0.081\right)\\$

after another year it becomes

$\Rightarrow 56,900\left( 1-0.081\right)-56,900\left( 1-0.081\right)\times 0.081\\\Rightarrow 56,900\left( 1-0.081\right)\cdot \left( 1-0.081\right)\\\Rightarrow 56,900\left( 1-0.081\right)^2$

After $x$ years it is

$\Rightarrow 56,900\left( 1-0.081\right)^x$

$\Rightarrow 56,900\left( 0.919\right)^x$
