Answer:

Surface Area: [tex]18ft^3[/tex]

Volume: [tex]44ft^2[/tex]

Step-by-step explanation:

Volume Formula --> base * height

[tex](4.5 * 2) * 2 = 9*2=18ft^3[/tex]

Surface Area Formula --> 2(width*length + height*length + height*width)

[tex]2((2*4.5) + (2*4.5)+(2*2)) = 2(9+9+4) = 2(22) = 44ft^2[/tex]

Answer:

Volume = 18 ft³

Surface area = 44 ft²

Step-by-step explanation:

Volume

Volume of a cuboid = base length × base width × height

Given:

Substitute given values into formula:

⇒ Volume = 4.5 × 2 × 2 = 18 ft³

Surface Area

Surface area = 2(base width × height) + 2(base length × height) + 2(base length × base width)

                      =2(2 × 2) + 2(4.5 × 2) + 2(4.5 × 2)

                      = 8 + 18 + 18

                      = 44 ft²

FROM MATH MULLIGAN

What is Lens Focal Length

Focal length, usually represented in millimeters (mm), is the basic description of a photographic lens. It is not a measurement of the actual length of a lens, but a calculation of an optical distance from the point where light rays converge to form a sharp image of an object to the digital sensor or 35mm film at the focal plane in the camera. The focal length of a lens is determined when the lens is focused at infinity.

Lens focal length tells us the angle of view—how much of the scene will be captured—and the magnification—how large individual elements will be. The longer the focal length, the narrower the angle of view and the higher the magnification. The shorter the focal length, the wider the angle of view and the lower the magnification.

The magnified length of the object is 10⁻¹ m

An image is said to be magnified when its size is greater than that of the object, and it is said to be diminished when its size is smaller than that of the object.

Given that,

A microscope magnifies an object 10³ times. The length of an object is 10⁻⁴ meters. The magnified length is:

10³ × 10⁻⁴ m

We can solve this by applying the Product of Powers Property. This property states that to multiply powers having the same base, we have to add the exponents.

10³ × 10⁻⁴ m

= 10³⁺⁽⁻⁴⁾ m

= 10³⁻⁴ m

= 10⁻¹ m

Hence, the magnified length is 10⁻¹  m.

Answer:

a) 6.10

Step-by-step explanation:

if you want to figure out the total number spent, then you simply add together the two amounts to get:

3.25+2.85=6.10

p.s. dont post such simple questions on brainly

Answer: a. $6.10

Step-by-step explanation:

2.85 + 3.25 = (2+3)+(.85+.25) = (5)+(1.10)=6.10
therefore, $6.10 is the right answer

Answer: Nancy is 12

Nancy = 5/6N =10

Step-by-step explanation:

Elizabeth = 5/6N

5/6N = 10

Divide both sides by 5/6

Using proportions, it is found that Dalisay hits the target more.

A proportion is a fraction of a total amount.

Kendra hits the target 3 times for every 5 misses, that is, she hits the target 3 out of 8 times, hence her proportion is:

pK = 3/8 = 0.375.

Dalisay hits 5 out of 12 times, hence:

pD = 5/12 = 0.4167.

Due to the higher proportion, Dalisay hits the target more.

Answer:

165.8 ft (nearest tenth)

Step-by-step explanation:

We can use the tan trig ratio to calculate the height of the tower.

[tex]\sf tan(\theta)=\dfrac{O}{A}[/tex]

where:

From inspection of the diagram:

Substituting these values into the trig tan ratio:

[tex]\sf \implies tan(37)=\dfrac{h}{220}[/tex]

Multiply both sides by 220:

[tex]\sf \implies 220tan(37)=h[/tex]

[tex]\sf \implies h=220tan(37)[/tex]

[tex]\sf \implies h=165.781891[/tex]

Therefore, the height of the tower is 165.8 ft (nearest tenth)

Answer:

50%

Step-by-step explanation:

Step one:

By convention, the dimension of a shape is described as

Lenght first, followed by width

Hence

lenght = 4 in

Width = 6 in

Step two:

Therefore, to achieve a new width of 3 in, the initial width must be divided by 2, which is a 50% reduction.

3/6*100

0.5*100

=50%

Answer:its 75 percent

Answer:

$32.39

Step-by-step explanation:

She has a 15-gallon tank and it has 1/5 a tank of gas left (so about 3/15)

Because she needs to refill it and already has 1/5, she'll only need to pay for 4/5 a tank of gas (12/15).

So the equation should be 12 times $2.699.

12 × 2.699 = 32.388

Then, round to the nearest cent.

32.388 = $32.39

Never congruent

Step-by-step explanation:

A dilation is a transformation that makes an image that is thr same shape as the original, but a DIFFERENT SIZE.

Congruent shapes means they both have the same shape AND size.

Answer:

The Last option

Step-by-step explanation:

We see this figure has eight faces, so we already know the answer choice is D, because answer choice D is the only option with 8 faces.

Now let's prove this using Euler's Formula

F = Faces

V = Vertices

E = Edges

We see 12 vertices, 8 faces, and 18 edges. Now plug in the formula.

F + V = E + 2

8 + 12 = 18 + 2

20 = 20
