Anika is hiking on a rectengular trail at the nation park there are four resting spots along the corners of the trail on the map they are marked with coordinates of -2,2) 1,2) 1,-2) and -2,-2 if rach unit represents 1 mile find the perimiter of the trail in miles using the coordinates
Answer:
The perimeter is 14 units
Step-by-step explanation:
Given
[tex]A = (-2,2)[/tex]
[tex]B = (1,2)[/tex]
[tex]C = (1,-2)[/tex]
[tex]D = (-2,-2)[/tex]
Required
Determine the perimeter
To do this, we simply calculate the distance between the sides of the rectangle i.e. AB, BC, CD and DA.
Distance (d) is calculated using:
[tex]d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}[/tex]
For AB
[tex]A = (-2,2)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]B = (1,2)[/tex] --- [tex](x_2,y_2)[/tex]
[tex]AB = \sqrt{(-2 - 1)^2 + (2 - 2)^2} = \sqrt{9} = 3[/tex]
For BC
[tex]B = (1,2)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]C = (1,-2)[/tex] --- [tex](x_2,y_2)[/tex]
[tex]BC = \sqrt{(1-1)^2 + (2--2)^2} = \sqrt{16} = 4[/tex]
For CD
[tex]C = (1,-2)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]D = (-2,-2)[/tex] --- [tex](x_2,y_2)[/tex]
[tex]CD = \sqrt{(1 - -2)^2 + (-2 -- 2)^2} = \sqrt{9} = 3[/tex]
For DA
[tex]D = (-2,-2)[/tex] --- [tex](x_1,y_1)[/tex]
[tex]A = (-2,2)[/tex] --- [tex](x_2,y_2)[/tex]
[tex]DA = \sqrt{(-2--2)^2 + (-2-2)^2} = \sqrt{16} = 4[/tex]
So, the perimeter (P) is:
[tex]P = AB + BC + CD + DA[/tex]
[tex]P = 3 +4 + 3 + 4[/tex]
[tex]P = 14[/tex]
The perimeter is 14 units
Your goal is to fill a right circular cylinder shaped bucket with water. The bucket has a radius of 6 inches and a height of 12 inches. If you use a right circular cone with a 3 inch radius and a 4 inch height, how many scoops of water will it take to fill the bucket ?
Answer:
36
Step-by-step explanation:
to answer this question :
determine the volume of the cylinder and the cone. Divide the volume of the cylinder by the volume of the coneVolume of a cylinder = nr^2h
n = 22/7
r = radius = 6
h = height = 12
(22/7) x (6^2) x (12) = 1357.71 in^3
Volume of a cone 1/3(nr^2h)
n = 22/7
r = radius = 3
h = height =
4
(1/3) x (22/7) x (3^2) x (4) = 37.71
1357.71 / 37.71 = 36 times

hey i just need an answer and possibly a step by step thanks !!!
Answer: 1517.54
Step-by-step explanation:
So we can divide solving this question into two parts: the 2% compound interest and the 5% compound interest.
We know that the compound interest equations is A = P(1+r/n)^nt where:
A is final amount
P is principal (initial) amount
r is interest rate
n is number times interest compounded
t is number of time periods
Given this, in the 2% compound we know:
A = ?
P = 1200
r = 2%
n = 1 (because it didn't say how many times compounded so we assume 1)
t = 2
This becomes:
A = 1200 (1 + (0.02/1))^ 1 * 2
A = 1248.48
Because we switching to 5% from 2%, we can assume that the final amount from the 2% will be the initial amount in the 5%. Thus:
A = ?
P = 1248.48
r = 5%
n = 1
t = 4 (because there were 6 years in total and we used 2 years for 2%)
This becomes:
A = 1248.48 (1 + (0.05/1))^ 1 * 4
A = 1517.54
Is [tex]\frac{x^{2}}{2}[/tex] an equation that can be simplified? If so, what is its simplified form?

Mateo decide pedir un préstamo de 600 soles durante 2 años a un banco el cual le ofrece una tasa de interés anual de 16%calcula al interés simple y el monto total que pagará al término de 2 años
Answer:
192 and 792
Step-by-step explanation:
Given that
The principal is 600 soles
The Time period is 2 years
The Rate of interest is 16%
We need to find out the simple interest and the total amount paid at the end of 2 years
As we know that
SImple interest is
= Principal × rate of interest × time period
= 600 × 16% × 2
= 192
And, the amount is
= Principal + interest
= 600 + 192
= 792

Plz help me! Brainlist will be picked.
Answer:
$2.96
Step-by-step explanation:
1.15x = 3.40 x = last year's price. If there price was exactly the same, I would put 1x, but this year's price is 15% or .15 higher.
1.15x = 3.40 Divide both sides by 1.15 and round to the nearest cent.
x = 2.96
Check:
Last year + 15% (.15)
2.96 + .15(2.96)
2.96 + .44 rounded to the nearest cent
3.40

2410.26
Step-by-step explanation:
This is a bit complicated but, you have to take 3.5% of 2,250 (2,250*0.035=78.75). Then add 78.75 to the total (2,250) (2328.75 new total). Next take 3.5% of the new total and repeat that process and you end up with 241.26.
A.45
B.30
C.90
D.180
E.40
F.55
G.130
H.50
Answer:
m<4=40
Step-by-step explanation:
Supplementary angles form 180 degrees
m<3 is vertical to the 50 degree angle which is equal.
so. m<3=50
m<5=90
90+50=140
180-140=40
m<4=40

Answer: other than 7
Step-by-step explanation:
Given
Equation is [tex]x^2+7=x^2+?[/tex]
For an equation to have no solution, the missing number can be any number other than 7
because if we put 7 then it justifies the equation i.e. [tex]7=7[/tex] while on the other hand for a number other than 7, it does not justify the equation.
