Answer:

49.59°

Step-by-step explanation:

Using trigonometry, we can obtain AVA's angle of elevation to UFO

Using the relation :

Tanθ = opposite / Adjacent

Tan θ = 195 / 166

θ = tan⁻¹(195÷166)

= 49.59°

The scale factor of the dilation of the given object is 4.

The scale factor of dilation of an object is determined by taking the ratio of image length to corresponding object length.

The scale factor of the dilation of the object is calculated as follows;

[tex]S.D = \frac{32\pi \ cm^2}{8\pi \ cm^2} \\\\S.D = 4[/tex]

Thus, the scale factor of the dilation of the given object is 4.

Answer:

5 days

Step-by-step explanation:

dogs, combined, eat 80 ounches of food daily

there are 16 ounces in one pound so there are 25x16, or 400 ounces, in a 25-pound bag

400/80 = 5

25-pound bag would last 5 days

One bag of dog food volunteered by Amelia, Which have quantity of 25 pounds  will last for 5 days.

What is ratio?

Ratio is mathematical term, which we use for comparing two or more terms. basically it indicates that how much big or small is number in compared to another.

Given that,

Every day, Amelia puts out 10 ounces of food for each of the 8 dogs.

Dog food comes in 25-pound bags.

And it is know that,

1 pound = 16 ounce;

so by that way it can state that,

Dog food for 25-pound bag will be equal to;

25*16

400 ounce.

Everyday requirement of dog food is 8*10 = 80 ounce/day

Number of days food will  last= Available quantity/Everyday requirement

Number of days food will  last= 400/80

Number of days food will  last= 5 days

Hence, One bag of food will be enough for 5 days.

Answer:

58 :)

Step-by-step explanation:

the two angles make up a right angle with is 90 degrees so 90 minus 32 is 58.

Answer:

SO we can see that x is part of a 90 degree angle

whats also included in the 90 degree angle alongside x is 32 so the equation will look like this

x+32=90

just solve from here

90-32=58 = x

Hello! answer: 276

I dont know for sure though cause the model looks different from what I've seen before so answer at your own risk but I'm pretty sure this is right Hope that helps!

Ok so what I did was base × height for the rectangles because thats the formula for those those I got 70 for both the left and right the left isn't showing but I'm assuming its there its 70 for both because 14 × 5 = 70 then for the bottom is 112 because 14 × 8 = 112 then the two triangles are 12 each because 8 × 3 = 24 then divide by 2 because thats what you do for triangles then I just add all these numbers up so... 70 + 70 + 112 + 12 + 12 = 276

Answer:

[tex]x = 3.7[/tex]

Step-by-step explanation:

We can find the side of the hypotenuse by applying pythagorean theorem.

[tex] {5}^{2} + {5}^{2} = {x}^{2} [/tex]

[tex]25 + 25 = {x}^{2} [/tex]

[tex]50 = {x}^{2} [/tex]

[tex]x = 5 \sqrt{2} [/tex]

Now we can apply pythagorean theorem on the other triangle

[tex](5 \sqrt{2} ) {}^{2} + {x}^{2} = {8}^{2} [/tex]

[tex]50 + {x}^{2} = 64[/tex]

[tex] {x}^{2} = 14[/tex]

[tex]x = \sqrt{14} [/tex]

[tex]x = 3.7[/tex]

Answer:

Step-by-step explanation:

use Pythagoras's   theorem  to find the hypontenuse of the isosceles triangle on the right side.

hyp = sqrt [ 5^2 + 5^2 ]

hyp = sqrt [ 50 ]

hyp = 7.0710678

now we know the adjacent side of the triangle on the left , since it's the same as the hypotenuse of the triangle on the right.

SOH CAH TOA ( to remember how the trig funct. fit on triangles)

CAH  Cos(Ф) = adj / hyp

cos(Ф) = 7.0710678 / 8

Ф = arcCos(  7.0710678 / 8 )

Ф = 27.8855668°

TOA  Tan(Ф) = x / 7.0710678

Tan( 27.8855668° ) =  x / 7.0710678

7.0710678 * Tan( 27.8855668° ) = x

3.741657 = x

x = 3.7  ( to the nearest 10th )

Answer:

1/6

Step-by-step explanation:

3 out of 18 marbles are green. 3/18 can be reduced to 1/6 because both 3 and 18 are divisible by 3.

3/3=1

18/3=6

1/6

The probability of picking a green marble is 1/6.

To find the probability of picking a green marble, we need to consider the total number of marbles and the number of green marbles in the jar. The jar contains a total of 18 marbles, and out of these, there are 3 green marbles.

The probability of an event happening is calculated by dividing the number of favorable outcomes (in this case, the number of green marbles) by the total number of possible outcomes (the total number of marbles in the jar).

So, the probability of picking a green marble can be written as:

P(green marble) = Number of green marbles / Total number of marbles

Substituting the values, we get: P(green marble) = 3 / 18

To simplify this fraction, we can divide both the numerator and denominator by their greatest common divisor, which is 3. Dividing both 3 and 18 by 3, we get: P(green marble) = 1 / 6

Therefore, the probability of picking a green marble from the jar is 1/6. This means that if you randomly pick a marble from the jar, there is a 1 in 6 chance that it will be green.
