someone wanna help me fill this out? ​

Answer:

The volume of the metal used is 5277.9 cm³.

Step-by-step explanation:

The volume of a cylinder is given by:

[tex] V = \pi r^{2} h [/tex]

Where:

r: is the radius

h: is the height = 50 cm

The volume of metal ([tex]V_{m}[/tex]) can be found by subtracting the internal volume ([tex]V_{i}[/tex]) from the external volume ([tex]V_{e}[/tex]):

[tex] V_{m} = V_{e} - V_{i} [/tex]

[tex] V_{m} = \pi r_{e}^{2} h - \pi r_{i}^{2} h [/tex]    

The external radius is given by the sum of the internal radius with the tickness:

[tex] r_{e} = t + r_{i} [/tex]

Hence, the volume is:

[tex] V_{m} = \pi*50 cm((2.4 cm + 5.8 cm)^{2} - (5.8 cm)^{2}) = 5277.9 cm^{3} [/tex]

Therefore, the volume of the metal used is 5277.9 cm³.

I hope it helps you!                                                      

Answer: 2.18

Step-by-step explanation:

Angle B= 180- (Angle A + Angle C)

= 180- (70+90)

= 180-160=20

((sin A)/BC)=((sin B)/AC)

((sin 70)/6)=((sin 20)/AC)

(0.9/6)=(0.3/AC)

AC= (6*0.3)/0.9

AC= 2.18

Actually Welcome to the Concept of the functions.

According to the power of the functions, positive power is more than the negative one hence, for any value of x, the value of function y is always positive.

Hence the answer is option D.)

===>

x==> - infinite, y => infinite and x=> infinte, y=> infinite

Step-by-step explanation:

the bottom angles are gonna be the same and a triangle is 180 degrees total so

Answer:

Near the mark at the bottom reading 100 mL

Step-by-step explanation:

We know that 1000 mL = 1 L

It means that 1 liter of a liquid contains 1000 milliliter of the liquid. In other words, in 1 liter there is 1000 mL of the liquid. And milliliter means one thousandth of a liter.  

So when we pour 97 mL of the water in a jar which has a capacity to fill water up to 1 L or 1000 mL, the water filling the jar will come close to the bottom of the jar which is approximately 100 mL .  It will rise up to the mark which reads 100 mL in the jar that is graduated.

over 4

Answer:

38%

Step-by-step explanation:

So first you need to find what 434/700 is because that is when she fell asleep. Divide each side by 2 to get 217/350. Use division to find the decimal. Once you are done with that, you get 0.62. You then subtract 0.62 from 1 because that is the amount of when she fell asleep. 1-0.62=0.38. 0.38 is also 38% so Moussa fell asleep for 38% of the trip.

Hopefully this helps you

Step-by-step explanation:

The ratio and proportion is the mathematical concept that can explain the correlation between the size of a dog and the amount of food it eats. For example dogs weighing 3 to 7 kg should consume 67 to 112 grams of food per day, that is, the amount of food must be proportional to the weight of the dog.

The ratio and proportion are interconnected concepts that allow the understanding of comparison between quantities.

Step-by-step explanation:

area of a rectangle = length x breath

2i) A= lxb

=7.5×2.5 = 18.75 m

2ii) 350cm= 3.5m

120cm = 1.2m

A= lx b

=3.5x1.2

=4.2m
