Ava and Taha are staring up at a UFO. Ava is directly east of the UFO and Taha is directly west. Ava is 205 feet from the UFO and Taha is 195 feet from the UFO. Ava and Taha are 166 feet from each other. Find Ava's angle of elevation to the UFO in degrees.
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°
Solve the equation 5y – 7x = 7 for y. 7 7 Oy x+ o y = 35x + 35 Оу — als 7 5 o y= 35 – 35x
Answer:
1st option
Step-by-step explanation:
Given
5y - 7x = 7 ( add 7x to both sides )
5y = 7x + 7 ( divide the terms by 5 )
y = [tex]\frac{7}{5}[/tex] x + [tex]\frac{7}{5}[/tex]
A rectangle with positive are has length represented by the expression 3x^2+5x-8 and width by 2x^2 +6x write an expression in terms of c for the perimeter and area of the rectangle give your answer in standard polynomial form and show your work
Answer:
[tex]c=10x^2+22x-16\\A=6x^4+28x^3+14x^2-48x[/tex]
Step-by-step explanation:
Given
Length is [tex]l=3x^2+5x-8[/tex]
Width is [tex]w=2x^2+6x[/tex]
Perimeter of the rectangle is the sum of the sides
[tex]\Rightarrow c=2(3x^2+5x-8+2x^2+6x)\\\Rightarrow c=2(5x^2+11x-8)\\\Rightarrow c=10x^2+22x-16[/tex]
Area is given by
[tex]\Rightarrow A=(3x^2+5x-8)(2x^2+6x)\\\Rightarrow A=6x^4+18x^3+10x^3+30x^2-16x^2-48x\\\Rightarrow A=6x^4+28x^3+14x^2-48x[/tex]

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

graph all vertical and horizontal asymptotes of the rational function.
Answer:
Below in bold.
Step-by-step explanation:
When x = 4 the denominator = 0 so the vertical asymptote is x = 4.
When x approaches negative and positive infinity f(x) approaches zero so the horizotal asymptote is y = 0 ( the x-axis).

A jar contains 18 marbles that are all the same size. It contains 7 purple, 3 green, and 8 orange marble. What is the probability of picking a green marble? Type your probability as a fraction in the simplest form.
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.

A cylindrical cake with a height of 5 inches has a 30 degree slice removed. If the volume of the removed slice is 40 inches what is the approximate radius of the cake
Answer: [tex]5.52\ in.[/tex]
Step-by-step explanation:
Given
Height of cylindrical cake is [tex]h=5\ in.[/tex]
[tex]30^{\circ}[/tex] slice is removed
Volume of the slice is [tex]V=40\ in.^3[/tex]
Area of slice is
[tex]\Rightarrow \dfrac{30^{\circ}}{360^{\circ}}\times \pi r^2\\\\\Rightarrow \dfrac{\pi r^2}{12}[/tex]
Volume of slice will be multiplication of area and height
[tex]\Rightarrow V=A\times h\\\\\Rightarrow 40=\dfrac{\pi r^2}{12}\times 5\\\\\Rightarrow \pi r^2=\dfrac{40\times 12}{5}\\\\\Rightarrow r^2=\dfrac{40\times 12}{3.142\times 5}\\\\\Rightarrow r^2=30.55\\\Rightarrow r=5.52\ in.[/tex]
Hence, the radius of the cake is [tex]5.52\ in.[/tex]

(8.08×106)×(7.5×10−2)
This can also be expressed as;
(8.08*7.5) * (10^6*10^-2)
= 60.6*10^4
= 606000
express in scientific form;
606000

Suppose the total cost, C, of renting a car is

equation best describes this relationship if
d represents the number of days the car is
rented?
F C = 100d - 25

HC=25d - 100
J C= 25d + 100
Answer:
the last one
Step-by-step explanation:
the 100 dollars is an initial fee so it won't be multiplied at all. the 25 is daily so you would multiply that by each day which is d. you would add the 100 dollars because it wants to know the total price in the end. I hope this helps and I am truly sorry if it is not right.

Amelia volunteers at her town's animal shelter. Every day, she puts out 10 ounces of food for each of the 8 dogs. If dog food comes in 25-pound bags, how many days will one bag of dog food last?
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.
