Answer:

Step-by-step explanation:

The equation that best represent the volume of the cylinder in cubic inches is V = π4²h.

A cylinder is simply a 3-dimensional shape having two parallel circular bases joined by a curved surface.

The volume of a cylinder is expressed as;

V = π × r² × h

Where r is radius of the circular base, h is height and π is constant pi.

Given that;

V = π × r² × h

V = π × (4)² × h

V = π4²h

Therefore, the equation that best represent the volume of the cylinder in cubic inches is V = π4²h.

Answer:

5(7+3)

Step-by-step explanation:

Because 7+3=10 and 10x5=50. And also 35+15=50 so 50 and 50

Hey there!

35 + 15

= 50

Option A.

7(5 + 2)

= 7(5) + 7(2)

= 35 + 14

= 49

49 ≠ 50

Option B.
5(6 + 3)

= 5(6) + 5(3)

= 30 + 15

= 45

45 ≠ 50

Option C.

5(7 + 3)

= 5(7) + 5(3)

= 35 + 15

= 50

50 = 50

Option D.
7(5 + 3)

= 7(5) + 7(3)

= 35 + 21

= 56

56 ≠ 50

Therefore, the answer should be:

Option C. 5(7 + 3)

Good luck on your assignment & enjoy your day!

The solution of the given inequality is  x/10 + 6 ≥ 8 will be x ≥  20.

Inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.

Given inequality is:-

x / 10  +  6 ≥  8

Put the value of x = 20

20 /10 +  6  ≥ 8

2  +  6   ≥   8

8    ≥    8

So the value of x will be greater than 20 or equal to 20.

Therefore the solution of the given inequality is  x/10 + 6 ≥ 8 will be x ≥  20.

  b)  £5.40

Step-by-step explanation:

In this context, "of" means "times".

__

  1/4 × £42 = £(42/4) = £10.50

__

  2/5 × £13.50 = £(2·13.50/5) = £(27/5) = £5.40

Additional comment

The symbol "£" is a currency symbol identifying the units of the associated number. For algebraic purposes, any symbol representing units can be treated as though it were a variable.

In this question of means multiplication.

Let us start solve this question

Question 1

[tex] \small\rm{ \dfrac{1}{4} \: of \: £ \: 42}[/tex]

First we will convert whole number into a fraction

(Any number can be converted to fraction if you use 1 as the denominator)

[tex] \small\sf{ \dfrac{1}{4} \: \times \: \dfrac{42}{1}}[/tex]

Now we will multiply the numerators and denominators.

[tex] \small\sf{ \dfrac{42}{4} = £10.50 } [/tex]

Question 2

[tex] \small\rm{\dfrac{2}{5} \: of \: £ \: 13.50}[/tex]

First we will convert whole number into a fraction

[tex] \small\sf{ \dfrac{2}{5} \times \dfrac{13.50}{1} } [/tex]

Now we will multiply the numerators and denominators.

Step-by-step explanation:

The height of a trapezoid is the distance between the parallel bases.

__

Here, one base lies on the horizontal line y=5, and the other lies on the horizontal line y = -6. The distance between them is ...

  5 -(-6) = 5 +6 = 11

You can also find this distance by counting the grid squares between the two parallel lines.

The height of the trapezoid is 11 units.

_____

Additional comment

The base lengths are ...

  AB = 2 -(-5) = 7

  CD = 8 -(-7) = 15

The area is 1/2(b1 +b2)h = (1/2)(7 +15)(11) = 121 square units.

Answer:

you need to width x height x length b

Step-by-step explanation:

Length, width, and height are measurements that allow us to indicate the volume of geometric bodies. The length (6 cm) and the width (10 cm) correspond to the horizontal dimension. On the other hand, the height      (5 cm)refers to the vertical dimension.

Answer:

1/4

Step-by-step explanation:

If total ride is 48 minutes, then she should have covered 1/4 the distance in 12 minutes cuz in 24 minutes she would cover 1/2 and in 36 minutes should would cover 3/4 and in 48 minute should cover the ride 1.

Answer:

f(x + 2) = 4x² + 16x + 13

Step-by-step explanation:

f(x) = 4x² - 3

Then

f(x + 2) = 4(x + 2)² - 3

           = 4(x² + 4x + 2²) - 3

           = 4(x² + 4x + 4) - 3

           = 4x² + 16x + 16 - 3

           = 4x² + 16x + 13

Three possibilities

For red line

If h is negative then and k is positive then

then they will have two vertical asymptotes one on positive x and other on negative x

If h is negative and k is negative then the side part underroot with x turns negative I e x-(something) then they will form parabolas

You may look purple one

For all values of negative sum of h and k

example √x-k

The graph is parabola (Green one)

For h and k are equal the denominator yields √x and it stops at origin on downwards .(Blue one)

For all values of positive sum of h and k eg denominator as √x+k the graph will be like red one

[tex]1 + 1 = 2[/tex]

Step-by-step explanation:

1 + 1 is equal to 2 because it is- at least that's what we believe the answer to be. It doesn't have to, but it is just what we as humans have come to recognize because it is internationally accepted.

Heck, you don't need to be a genius to understand that when you inherently have exactly one more of a thing, you have more of it. Numbers are just a way to represent more (or less if we're talking negatives). Now, we'll probably never understand why mathematics is so beautifully synchronized with our world, but it is, and we as a sentient species have come to recognize that for the longest time.

Numbers are abstract, as long as you are consistent, anything can be a number if you give it value. [tex]1+1[/tex] doesn't have to equal [tex]2[/tex], if we wanted we could make it equal to [tex]:)[/tex]. [tex]1 + 1 =\ :)[/tex]

Or calculating integrals:

[tex]\int\limits^{0.5}_{0} {8xe^{:)x}} \, dx\\= \frac{xe^{:)x}}{:)}-\int\limits{\frac{e^{:)x}}{:)}} \, dx\\= 4xe^{:)x} - :)e^{:)x} + C = (4x-:))e^{:)x} + C\\=(4x-:))e^{:)x}|^{0.5}_{0}\\= (4(0.5)-:))e^{:)(0.5)} - (4(0)-:))e^{:)(0)}\\= :)[/tex]

Answer:

693.19 m^2.

Step-by-step explanation:

This consists of 2 triangles and 3 rectangles,

Surface area = 2 * 1/2 * 3 * 9 + 9*31 + 3*31 + 9.49*31

=  27 + 279 + 93 + 294.19

= 693.19 m^2

Answer:

  406.3 cm²

Step-by-step explanation:

The total surface area is the sum of the base area and the lateral area. The lateral area is the sum of the areas of the 6 congruent triangular faces.

__

Each triangular face has a base of 8 cm and a slant height of 10 cm. Its area is ...

  A = 1/2bh

  A = 1/2(8 cm)(10 cm) = 40 cm²

Then the area of 6 faces is 6×40 cm² = 240 cm².

The base area is given.

The total area is the sum of the lateral area and the base area:

  total area = 240 cm² +166.3 cm² = 406.3 cm²

The surface area is about 406.3 cm².

Step-by-step explanation:

-2 1/3 - ( - 5)

We are subtracting a negative which is like adding

-2 1/3 + (  5)

The signs are different so we subtract and take the sign of the larger

5 - 2 1/3

Borr from the 5

4 3/3 - 2 1/3

2 2/3

The sign of the larger was positive so the answer is positive
