Answer:
A
Step-by-step explanation:
the total is 25.92 and Elaina buys 2.57 eggs. So, you would have to first subtract 2.57 from 25.92 . Then she buys 5 bags of potatoes for x price.
This means that 23.35 (25.92-2.57) will have to be divided by 5 to get the price of 1 bag of potatoes.
x= 4.67

X. 120 Y. 30 Z. 36.5
Step-by-step explanation:
X. 360-107-133= 120
Y. Length of AB is equal to 120, so angles y and C are equal to 60. 60/2= 30

Step-by-step explanation:
Given the expression
(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
= 60.6*10^4
= 6.06*10^1*10^4
= 6.06 * 10^5

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°

Find the selling price. Cost to store: $20 Mark-up: 15% What is the selling price?
Answer:
$23
Step-by-step explanation:
First, we find what is 15% of $20.
0.15 times 20 is 3. Therefore, we know there was a markup of $3.
Then, we add the mark-up to the cost to store, and get $23.
So, the selling price is $23.

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 )

Prove
that BUGS is a trapezoid with coordinates B(-2,-1), U(0,3), G(3,2) and S(4,-3).
Answer:
Proved
Step-by-step explanation:
Given
[tex]B =(-2,-1)[/tex]
[tex]U = (0,3)[/tex]
[tex]G = (3,2)[/tex]
[tex]S = (4,-3)[/tex]
Required
Prove BUGS is a trapezoid
Given the coordinates, to prove a trapezoid; all we need to do is to check if one pair of sides is parallel.
Taking BU and GS as a pair
First, we calculate the slope using:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
For BU
[tex]B =(-2,-1)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]U = (0,3)[/tex] --- [tex](x_2,y_2)[/tex]
So, we have:
[tex]m = \frac{3 - -1}{0- -2}[/tex]
[tex]m = \frac{4}{2}[/tex]
[tex]m = 2[/tex]
For GS
[tex]G = (3,2)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]S = (4,-3)[/tex] --- [tex](x_2,y_2)[/tex]
So, we have:
[tex]m = \frac{-3-2}{4-3}[/tex]
[tex]m = \frac{-5}{1}[/tex]
[tex]m = -5[/tex]
The slope of BU and GS are not the same; hence, they are not parallel.
Taking BS and GU as a pair
Calculate the slope
For BS
[tex]B =(-2,-1)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]S = (4,-3)[/tex] --- [tex](x_2,y_2)[/tex]
So, we have:
[tex]m = \frac{-3 - -1}{4- -2}[/tex]
[tex]m = \frac{-2}{6}[/tex]
[tex]m = -\frac{1}{3}[/tex]
For GU
[tex]G = (3,2)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]U = (0,3)[/tex] --- [tex](x_2,y_2)[/tex]
So, we have:
[tex]m = \frac{3-2}{0-3}[/tex]
[tex]m = \frac{1}{-3}[/tex]
[tex]m = -\frac{1}{3}[/tex]
The slope of BS and GU are the same; hence, they are parallel.
BUGS is a trapezoid because BS and GU have the same slope
5. A 50-inch piece of wire is bent into the shape of a rectangle. Find the dimensions of the rectangle
of maximum area that can be formed from the wire,
Answer:
length = 12.5 in, width = 12.5 in, Area = 156.25 in²
Step-by-step explanation:
To get the maximum area, the wire can be shaped into a square. We can say that the length and width of the rectangle must be equal to each other, and call this value "x".
Therefore, we can write an equation for the perimeter:
2x + 2x = 50 4x = 50 x = 12.5The area of the rectangle is calculated using the formula:
A = lwOr in our case, the area of the rectangle is the area of a square:
A = x²Substitute x = 12.5 into this equation.
A = (12.5)² A = 156.25The maximum area that can be formed from the wire is 156.25 in², and the dimensions of the rectangle are 12.5 x 12.5 in.
