The main tank has a radius of 70 feet. What is the volume of the quarter sphere sized tank round your answer to the nearest whole number. You must explain your answer using words and show all work for full credit.

Answer:

12

Step-by-step explanation:

[tex] \frac{4}{3} = \frac{x}{9} \\ \\ \implies \: 3x = 4 \times 9 \\ \\ \implies \: 3x =36 \\ \\ \implies \: x = \frac{36}{3} \\ \\ \implies \: x =12[/tex]

Answer:

12

Step-by-step explanation:

or;4/3=X/9

or;3x=4×9

or;3x=36

or;X=36/3

Therefore;X=12

The equation ,[tex]-2x^2+5xy-7y^2+9x-7y+13=0[/tex] represents a conic. The discriminant is is -31 , so the represents an ellipse .

A curve obtained by a cone and a plane is called conic .

Here given equation is

[tex]-2x^2+5xy-7y^2+9x-7y+13=0[/tex]

we know that discriminants of equation

[tex]$$A x^{2}+B x y+C y^{2}+D x+E y+F=0$$[/tex]

is [tex]$$D=B^{2}-4 A C$$[/tex]

and if

D<0  it's ellipse

D=0 it's parabola

D>0 It's  hyperbola

Here, the is

[tex]$$D=5^{2}-4(-2)(-7)=-31$$[/tex]

Hence it's an ellipse

Answer:

80

Step-by-step explanation:

i gotchuuuuu

okok so a really easy way that this can be done is by not doing the full trapezoid, but splitting it up into 2 triangles and 1 rectangle

area of triangle: 1/2BH

area of rectangle: LW

Ookie so first the triangles:

both have the exact same measurements:

7 is the base, and the height is 8. Even tho it doesn't say 8 on one of them, we can visually see that it is the same height.

So, for BOTH triangles, 8*7=56, divided by 2=28.

Now, the rectangle:

width is 3, and length is 8.

8*3=24.

ADD TOGETHER: 28+28+24=80

AREA=80

Answer:

80

Step-by-step explanation:

area of the two triangles

= (7x8)/2x2

= 56

area of the rectangle

= 8x3 = 24

area of the trapezoid

= 56+24

=80

Answer:

0.0073

Step-by-step explanation:

<3

Answer:

0.0025

Step-by-step explanation:

This is because , you have the number 75, and dividing that by 3 is 25, but since our number is 0.75, that means we are adding the 2 zeros from our 300 and add it on to be to 0.0025, this won’t work in some situations.

Hope that helps!

Answer:

50.24 cm^2

Step-by-step explanation:

The formula for the area of a circle is A = πr^2

The radius is half of the diameter so r = 4

So now you can solve:

A = 3.14(4)^2

= 50.24 cm^2

Answer:

  14

Step-by-step explanation:

The triangle inequality is usually expressed as ...

  a +b > c

for any permutation of a, b, c.

Here, that would mean ...

  1 + 14 > c

  c < 15

The largest whole-number value that the third side (c) can have is 14.

_____

Additional comments

Some authors write the triangle inequality as ...

  a +b ≥ c

If you use that version, the longest side could be 15. Such a "triangle" would look like a line segment, and have zero area.

__

We can also check the shortest length:

  c +1 > 14

  c > 13

The smallest whole-number value for the shortest side is also 14. That is, the only triangle with whole-number side lengths of 1 and 14 will be an isosceles triangle with two sides of length 14.

Answer:

a = 92° , b = c = 143°

Step-by-step explanation:

a and 88° are same- side interior angles and sum to 180° , that is

a + 88° = 180° ( subtract 88° from both sides )

a = 92°

b and 37° are same- side interior angles and sum to 180° , then

b + 37° = 180° ( subtract 37° from both sides )

b = 143°

b and c are corresponding angles and are congruent , then

c = b = 143°

Greeting Card = 3.79

Total Cost = 5.11

Post cards = x

Equation

Total Cost = Greeting Card + 4x

Solution

Substitute the gives into the equation

5.11 = 3.79 + 4x                       Subtract 3.79 from both sides

5.11 - 3.79 = 3.79 - 3.79 + 4x  Combine

1.32 = 4x                                  Divide by 4

1.32/4 = 4x/4

x = 33

Step-by-step explanation:

The left side of the equation HAS TO BE GREATER THAN 3

So we take each ordered pair (x,y), plug it into the expression of left side of inequality and see which one is GREATER THAN 3. That's our answer.

A:

0.5x - 2y

0.5(-2) -2(0.5) = -2

NO

B:

0.5x - 2y

0.5(2) -2(1) = -1

NO

C:

0.5x -2y

0.5(2) -2(-1) = 3

NO

D:

0.5x -2y

0.5(-2) -2(-0.5) = 0

NO

None of them are solutions. C would have been a solution if the inequality had an "EQUAL SIGN" -- but it doesn't. Maybe the question is wrong, but if the question is right, then there is no correct answer.
