Please Help!!!!!!!! I just need the answer.

Answer:

Volume of the prop = 706.5 in³

Step-by-step explanation:

Volume of the prop given in the picture = Volume of hemisphere + Volume of the cone

Volume of the hemisphere = [tex]\frac{2}{3}\pi r^{3}[/tex]

where 'r' = radius of the hemisphere

For r = 5 in,

Volume of the hemisphere = [tex]\frac{2}{3}(3.14)(5)^{3}[/tex]

                                             = 261.67 in³

Volume of a cone = [tex]\frac{1}{3}\pi r^{2}h[/tex]

Here r = radius of the circular base

h = height of the cone

For 'r' = 5 in and h  17 in.

Volume of the cone = [tex]\frac{1}{3}(3.14)(5)^2(17)[/tex]

                                  = 444.83 in³

Volume of the prop = 261.67 + 444.83

                                 = 706.5 in³

Answer:

125x + 165 = y

Answer:

y = - 4x + 5

Step-by-step explanation:

(y-1)/ (5-1) = (x-1)/(-1)

y-1 / 4 = -x+1

y-1 = -4x+4

y = - 4x + 5

Answer:

4

Step-by-step explanation:

From the question,

Since both rectangle has a scale factor of 2,

L₁/L₂ = 2

Where L₁ and L₂ are the length of the first and second rectangle respectively

L₁ = 2L₂................ Equation 1

Also,

W₁/W₂ = 2............ Equation 2

Where W₁ and W₂ are the Width of the first and second rectangle respectively

W₁ = 2W₂

Area of a rectangle = Length × width

Area of first rectangle = L₁×W₁ = 2L₂×2W₂ = 4L₂W₂

Area of second rectangle = L₂×W₂= L₂W₂

The ratio of area = Area of the first rectangle/Area of the second rectangle = 4L₂W₂/L₂W₂ = 4

Answer:

4.925

Step-by-step explanation:

first you minus 20.8 from 1.1, after that you divide 19.7 by 4 and that's is how you would get 4.925.

Answer:

8,14,9 = yes

8 + 14 > 9 ✅

17,4,13 = yes

17 + 4 > 13 ✅

9,9,9 = yes

9 + 9 > 9 ✅

22,23,60 =  no

22 + 23 > 60 ❌

Step-by-step explanation:

we remove 76 in the numerator and in the denominator because they're the same number

The solution of the expression is,

⇒ 80 / 81

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

The expression is,

⇒ 76/81 x 80/76

Now, We can solve as;

⇒ 76/81 x 80/76

⇒ (76 × 80) / (81 × 76)

⇒ 80 / 81

Thus, The solution of the expression is,

⇒ 80 / 81

Answer:

5/6= 10/12

12/100<10/12

Answer:

Step-by-step explanation:

[tex]\frac{8}{2x} =\frac{x}{6} \\2x^{2} =8 \times 6\\x^{2} =24\\x= \pm 2\sqrt{3} \\BD=2 \sqrt{3}\\FG=2 *2 \sqrt{3}=4\sqrt{3}[/tex]

Subtract the deductible from the total:

350 - 150 = 200

Takashi then needs to pay 20% of what is left.

200 x 0.20 = 40

Takashi has to pay the 150 deductible plus 40 for a total of $190

Answer:

The speed of the car is 75 mph.

The speed of the truck is 56 mph.

Step-by-step explanation:

Call the speed of the truck (x) miles per hour. As per the given information, the car is (19) miles per hour faster. Thus, one can form expressions to represent the speeds of the vehicles.

car = ( x + 19 ) mph

truck = ( x ) mph

Using the formula, ( (speed) * (time) = (distance) ), one can say that the speed of the car, times the time it took plus the speed of the truck times the time will equal the distance between the two vehicles:

(( car speed )( time )) + (( truck speed )( time )) = ( distance between vehicles )

Substitute,

( ( x + 19 ) ( 8 ) ) + ( ( x ) ( 8 ) ) = 1048

Simplify,

8x + 152 + 8x = 1048

16x + 152 = 1048

       -152     -152

16x = 896

/16     /16

x = 56

Add (19) to find the speed of the car:

truck speed + 19

= 56 + 19

= 75

The speed of the car is 75 mph.

The speed of the truck is 56 mph.

Answer:

The truck traveled at 81

mph. The car traveled at 100

mph.

Answer:

The volume of existing cage = length x widht x height = 3 x 2 x 3 = 18 cubic ft

Now she wants cage with volume four times of this cage

New Volume = V1 = 18 x 4 = 72 cubic ft

Keeping length same = 3 ft

Length x width x height = V1

3 x Width x height = 72

Width x height = 72 /3

Width x height = 24

Now multiple of 24 must be the width and height.

Taking width = 6 ft and height = 4 ft, we will get our answer

Proof:

Length x width x height = V1

3 x 6 x 4 = 72
