The object below is made of solid plastic. It is a cylinder with an indentation at the top
in the shape of a cone.

What is the volume to the nearest tenth of a cubic inch, of the plastic object?​

The Object Below Is Made Of Solid Plastic. It Is A Cylinder With An Indentation At The Topin The Shape

Answers

Answer 1

Answer: 97.6 in3

Step-by-step explanation:

Hi, to answer this question we have to calculate the volume of the cylinder and subtract the volume of the cone:

Volume of a cylinder: π (diameter /2) ^2 (height)

Vcy = π (4 /2) ^2 (8) = π (2) ^2 (8) =100.5 in3

Volume of a cone = 1/3 π (diameter /2) ^2 (height)

V Co = 1/3 π (4/2) ^2 (0.7) = 1/3 π (2) ^2 (0.7) = 2.9 in3

Finally:

Volume of the cylinder - volume of the cone = 100.5-2.9 = 97.6 in3

Converse is the switching of the clauses

- EX: If I just ate mac and cheese, I am happy -> If I am happy, I just ate mac and cheese

First factor 2 from the quadratic:

Now complete the square:

So we have

[tex]2x^2+12x-14=0\implies2(x+3)^2-32=0[/tex]

Solve for x:

The Chain Reaction bike shop is running a special that allows a family to rent all the bikes and equipment they need for an hourly rate and a nonrefundable $15 deposit. The Morales family can rent bikes for 2 hours for $57. The cost of the rental can be represented by a linear function where x represents the number of hours the bikes are rented and y represents the total cost of the rental. What is the equation here and what are the slope and y-intercept?

Answers

Someone pls answer I need this as well

Answer:

y=21x+15, where 21 is the hourly rate and the slope, 15 is the non-refundable deposit, and y is the total amount payed

Step-by-step explanation:

the slope is the hourly rate, the y int is the deposit of 15$

thus,

to find the slope, we can use the equation:

57=m*2+15

42=2m

m=42/2

m=21

thus, the whole equation is:

y=21x+15, where 21 is the hourly rate and the slope, 15 is the non-refundable deposit, and y is the total amount payed

Step-by-step explanation:

The formula of the area of a circle is [tex]\pi r^{2}[/tex] and the diameter is double the amount as the radius, so the radius would be 4 feet. 4 squared is 16. Multiply that by pi to get your answer, 50.265[tex]ft^{2}[/tex].

Find the surface area of the regular pyramid. Write your answer as a decimal. (solved)

Answers

Answer:

The total surface area is 145.12 sq.m.

Step-by-step explanation:

We are supposed to find the surface area of given figure

Length of rectangular part = 15 m

Breadth of rectangular part = 8 m

Area of rectangular part =[tex]Length \times Breadth = 15 \times 8 = 120 sq.m.[/tex]

Diameter of semi circle = 8 m

Radius of semicircle = [tex]\frac{8}{2}=4 m[/tex]

Area of semicircle = [tex]\frac{\pi r^2 }{2}=\frac{3.14 \times 4^2}{2}=25.12 sq.m.[/tex]

Total surface area = 120+25.12=145.12 sq.m.

Hence The total surface area is 145.12 sq.m.

Which is true about the line whose equation is y + 2 = 0?

Answers

Answer:

The y-intercept is -2

Step-by-step explanation:

Based on the equation y + 2 = 0 (y = -2), you can eliminate all answers except for the second one. This is because, the y is the horizontal line, while the x is the vertical line. The value of x does not always equal the value of y, only sometimes. Finally, the slope of y = -2 is 0, not undefined. However, the slope of x = -2 is undefined.

A circular field is set into a square with an 800 m side length. Estimate the field's area.

A square where the vertical distance is labeled 800 meters.

About 5,000 m2
About 50,000 m2
About 500,000 m2
About 5,000,000 m2
About 50,000,000 m2

Answers

Answer:

c = 500,000

This is 6 digit number with 5 zero's.

We just multiply the radius ^2 by pi

D = 800m  R = 400

R^2 = 400 x 400 = 160000

A = 160000π = 502654.824574

We estimate from 160000 and just count the 0's on multiplication as long as the 10's don't change in that estimation.

we can show the workings as the counting loops under the 6 and 0's of 160000. = 5 units+ 1.

= 500,000 m^2

The governor of state A earns ​$49,610 more than the governor of state B. If the total of their salaries is ​$282,720​, find the salaries of each. The governor of state A earns ​$?, and the governor of state B earns ​$?.

Answers

Answer:

The governor of state A earns ​$ 166,165, and the governor of state B earns ​$ 116,555

Step-by-step explanation:

the governor of state A  salary = x+ 49610

the governor of state B salary = x

together : 282720 = x+49610 +x

282720 = 2x + 49610  subtract 49610 from both sides

282720-49610 = 2x

233110 = 2x divide by 2

x = 116555

plug in x in the governor of state A  salary = x+ 49610 = 116555 + 49610 = 166,165

Suppose you have one pyramid with a base that is 10 meters long and 10 meters wide with a slant that is 15 meters. Now, if the length of the base is

Answers

Answer:

The difference between area of pyramids is 125 sq.m.

Step-by-step explanation:

Length of base = 10m

Breadth of base = 10 m

Slant height = 15 m

Area of pyramid = Area of 5 bases

Area of pyramid = [tex]\frac{1}{2} \times 10 \times 15+\frac{1}{2} \times 10 \times 15+\frac{1}{2} \times 10 \times 15+\frac{1}{2} \times 10 \times 15+10 \times 10[/tex]

Area of pyramid = 400 sq.m.

Now the length of base is increased to 15

Length of base = 15m

Breadth of base = 10 m

Slant height = 15 m

Area of pyramid = Area of 5 bases

Area of pyramid =[tex]\frac{1}{2} \times 15 \times 15+\frac{1}{2} \times 15 \times 15+\frac{1}{2} \times 10 \times 15+\frac{1}{2} \times 10 \times 15+10 \times 10[/tex]

Area of new pyramid = 525 sq.m.

Difference between area of pyramids=525 sq.m. - 400 sq.,. = 125 sq.m.

Hence The difference between area of pyramids is 125 sq.m.
