Answer:

the cone holds only 1/3 as much water as the cylinder, which comes to 29 gallons

Step-by-step explanation:

Let the radius in both cases be r and the height in both cases h.

Cylinder volume is (area of base)(height), and

Cone volume is (1/3)(area of base)(height).

Thus, the cone holds only 1/3 as much water as the cylinder, which comes to 29 gallons.

Answer:

x=13.7

Step-by-step explanation:

CD=CB=6

AC=AD+CD => AC=9+6 => AC=15

AC^2= AB^2 + BC^2 => 15^2 = X^2 + 6^2 => 225 = X^2 + 36 => X^2 = 225 - 36 => X^2 = 189 => X=13.7

The value of x or measure of the tangent line is 13.7 units

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

We have to find the value of x

CD=CB =6 units

CA=CD+DA

CA=9+6

=15 units

By pythagoras theorem

6²+x²=15²

36+x²=225

x²=225-36

x²=189

x=13.7=14

Hence, the value of x or measure of the tangent line is 13.7 units

Answer:

BA

Step-by-step explanation:

Here, we want to get the hypotenuse side

The hypotenuse represents the longest side

it is the side that faces the largest angle in a right triangle

The largest angle in a right triangle is the right angle which is the angle 90

It is like the square at a corner at the vertex C

The side facing it here is the the length AB (BA)

Answer:

1) y = -3

2) y = 0

Step-by-step explanation:

1) When x = 2

4x – 3y = 17

4(2) - 3y = 17

8 - 3y = 17

-3y = 17 - 8

-3y = 9

y = -3

2) When x = 4

–2x + y = –8

-2(4) + y = -8

-8 + y = -8

y = -8 + 8

y = 0

Answer:

the part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.

Step-by-step explanation:

Answer:

algebra is basically where you have math, and you have to find an unknown number that is represented by a letter

Step-by-step explanation:

I have attached an image showing the sketch and the questions to answer.

Answer:

7) $1.28 per brick paver

8) 64 Sq.inches

9) $0.02 per Sq.inches

10) 0.4444 Sq.ft

11) 120 Sq.ft

12) Number of paver to cover patio = 270

Cost of that number = $345.6

Step-by-step explanation:

7) from the image attached, we can see that a box of 12 pavers cost $15.36.

Thus,cost of each brick paver = 15.36/12

>> $1.28 per brick paver

8) we see on the right of the image attached that the dimension of the brick paver is 8 inches length and 8 inches width.

Thus; square inches is the area = 8 × 8 = 64 Sq.inches

9) 1 paver has an area of 64 Sq. Inches. Thus, 12 pavers has an area of;

12 × 64 = 768 Sq.inches

Since cost of 12 pavers is $15.36

Thus coat per Sq inches of the pavers = 15.36/768 = $0.02 per Sq.inches

10) To find the Sq.ft each paver would cover, we will first convert the dimensions of the paver to ft.

Thus;

Length of 8 inches = 8/12 ft

Width of 8 inches = 8/12 ft

Area = (8/12) × (8/12)

Area = 4/9 Sq.ft = 0.4444 Sq.ft

11) The patio measures;

Length = 12 ft

Width = 10 ft.

Thus;

Area = 12 × 10 = 120 Sq.ft

12) Each paver has an area of 4/9 Sq.ft.

Thus;

Number of pavers to cover the patio = area of patio/area of each paver

Number of pavers to cover patio = 120/(4/9) = 270 pavers

12 pavers cost $15.36

Thus, 270 pavers will cost;

270 × 15.36/12 = $345.6

Answer:

A=36 ft²

Step-by-step explanation:

the formula for the area of a triangle is given as (b*h)/2, where b is the base and h is the height

we are given the a height of 3 and a base of 24

so we can plug what we know into the formula

A=(3*24)/2

multiply

A=72/2

divide

A=36 ft²

Answer:

-38a^2 - 10a - 25

Step-by-step explanation:

The highest power of a is a^2.  Combine the a^2 terms:

(-9 - 17 - 12)a^2 = -38a^2

Now combine the a terms:

(-8 - 9 + 7)a = -10a

Finally, combine the constants:  -8 - 17 = -25

Summing up these three results, we get:

-38a^2 - 10a - 25

Answer:
