Answer:
[tex]\sqrt{22.25}[/tex]
Step-by-step explanation:
4 ^ 2 is 16
2.5 ^ 2 is 6.25
16 + 6.25 is 22.25
The square root of 22.25 is undefined so...
[tex]\sqrt{22.25}[/tex]
22.5 = e(squared)
e = square root 22.5
= 4.74

Kendra and Dalisay practice archery. Kendra hits the target 3 times for every 5 misses. Dalisay hits the target 5 times for every 7 misses. Who hits the target more?
Answers
Using proportions, it is found that Dalisay hits the target more.
What is a proportion?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.

Alyssa is getting gas for her car. Her car’s 15-gallon tank has 1/5 a tank of gas left. If gas costs $2.699 per gallon, how much will she pay for gas, rounded to the nearest cent?
Answers
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

Under a dilation, are the pre-image and the image always,

Answers
Answer:
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.

Identify the number of vertices, edges, and faces of the polyhedron. Use your results to verify Euler's formula.
Answers
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

Kristine observes the top of a lookout tower from a point 220 ft from its base.
If the indicated angle of elevation measures 37º, how tall is the tower? Give your answer to the nearest tenth of a foot.
Answers
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:
[tex]\theta[/tex] = the angleO = the side opposite the angleA = the side adjacent the angleFrom inspection of the diagram:
[tex]\theta[/tex] = 37°O = height of tower (let's call this h)A = 220 ftSubstituting 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)

A camera lens magnifies an object 10 exponent 3 times. The length of an object is
10 exponent -4 centimeter. What is its magnified length?
Answers
Answer:
10^3/10^-4
Step-by-step explanation:
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
What is magnified length?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.
