Find The Volume Of The Given Shape. Round Your Answer To The Nearesthundredth If Necessary.

Answers

Answer 1

Answer:

65.97m³

Step-by-step explanation:

This is a right circular cone, so we will be using V = (1/3)(π)(r²)h

r = radius = 3m

h = height = 7m

V = (1/3)(π)(3m²)(7m) = 65.97m³

The bracket means to multiply.

What are the area and perimeter of a rectangle?

We know the perimeter of any 2D figure is the sum of the lengths of all the sides except the circle and the area of a rectangle is the product of its length and width.

From the given information each Pavel has an area of 4.5 square feet.

And the area of the driveway can be obtained by multiplying the length and width of the driveway which is,

= (21×18) sq feet.

= 378 sq feet.

Therefore, The number of pavers needed is,

= (378/4.5).

= 84 pavers.

Find the distance between C(-5,4) and Q(2,0)

Answers

9514 1404 393

Answer:

  √65 ≈ 8.06

Step-by-step explanation:

The distance formula is used for the purpose.

  d = √((x2 -x1)² +(y2 -y1)²)

  d = √((2 -(-5))² +(0 -4)²) = √(7² +(-4)²) = √(49 +16)

  d = √65 ≈ 8.0622577

The distance between C and Q is √65, about 8.06 units.

Are 25 milligrams lighter or heavier than 25 centigrams
Please help it's for homework and it says explain too so please help

Answers

Answer:

25 mg. is lighter than 25 cg.

Step-by-step explanation:

Well,

The prefix "milli" means thousandth and the prefix "centi" means hundredth.  So a milligram will be one-tenth of a centigram.

10 mg. = 1 cg.

25 mg. = 2.5 cg.

2.5 cg. < 25 cg.

25 mg. is lighter than 25 cg.

Answer:

25 milligrams are lighter, because 1 milligram equivales to 1 gram multiplied by 100.

Add a grocery store bananas cost $.90 each and oranges cost $.80 each Ava has $15 to spend if Ava wants to buy an equal amount of bananas and oranges at most how many of each can't you buy

Answers

Answer:

9

Step-by-step explanation:

We are given that

Cost of each banana=$0.90

Cost of each orange=$0.80

Ava have total money=$15

We have to find the number of each if Ava wants to buy an equal amount of bananas and oranges at most.

Let x be the number of each.

According to question

[tex]0.9x+0.8x=15[/tex]

[tex]1.7x=15[/tex]

[tex]x=\frac{15}{1.7}[/tex]

[tex]x=8.8\approx 9[/tex]

[tex]x=9(approximately)[/tex]

Hence, number of banana bought=9

Number of oranges bought=9

11. The slope of a line is 1/5. Label the two right
triangles with dimensions that would allow the
triangles to lie on the same line.

Answers

Answer:

Step-by-step explanation:

If the slope is 1/5, we can interpret this as rise/run = 1/5.  We could (if we wished to do so) find the hypotenuse by using the Pythagorean Theorem:

hypo = +sqrt( 1^2 + 5^2)

In this case we dilate the triangle defined by the slope 1/5:  

2/10,        1/10/(1/2),           10/50,        etc.,       all represent right triangles whose hypotenuses lie on the same line (the line with slope 1/5).

The two right triangles are shown in the graph

What are coordinates?

The coordinates in rectangular cartesian system are of the form -

(x, y)

where -

{x} - distance along x - axis.

{y} - distance along y - axis.

Given is the slope of the line as - {m} = 1/5.

Refer to the graph attached. The line -

y = (1/5)x

is plotted. It can be seen that (0, 0) and (10, 2) lie on the line.  For two right triangles to lie on the same line, draw two perpendiculars from point (10, 2) along the {x} axis and {y} axis. Refer to the triangles shown in the graph.

Therefore, two right triangles are shown in the graph.

An isosceles triangle has two congruent side lengths of 20 centimeters. The base of the triangle is 10 centimeters. Find the height of the

Answers

Answer:

(half of base)² + (height)² = (20)²

Step-by-step explanation:

In an isosceles triangle, the angle bisector from the 3rd angle to the opposite side is a perpendicular bisector, so you split the isosceles triangle into two congruent right triangles.

This technique of 'splitting the isosceles' is used a LOT.

You have $20 and earn $0.75 for each cup of orange juice you sell. Write an equation that represents the total amount A (in dollars) you have after selling j​ cups of orange juice.

Answers

Answer:

A= 20 + 0.75*j

Step-by-step explanation:

Giving the following information:

You have $20 and earn $0.75 for each cup of orange juice you sell.

To calculate the total amount of dollars (A), we need to use the following formula:

A= 20 + 0.75*j

j= number of cups

For example, for 15 cups:

A= 20 + 0.75*15

A= $31.25
