Answer:
The length of the park is approximately 1.77 kilometers
Step-by-step explanation:
The law of cosines is most appropriate when the measures of two sides and the included angle formed n=by the path of motion is known
The given parameters of the question are;
The distance from Mark's house to the edge of the park, a = 0.9 km
The distance from the far side of the park to Mark's house, c = 1.6 km
Whereby the included angle between lines, 'a' and 'c' is the ∠B = 85°, by cosine rule, we have;
b² = a² + c² - 2·a·c·cos(B)
Where;
b = The length of the park in kilometers
By plugging in the known values of 'a', 'b', and 'c', we get;
b² = 0.9² + 1.6² - 2 × 0.9 × 1.6 × cos(85°) ≈ 3.11899146089
∴ b = √(3.11899146089) ≈ 1.76606666377
Therefore, the length of the park, b ≈ 1.77 km.

Answer:
Step-by-step explanation:
A = 3M
J = 2A
J = 6M
Marie = M
Andre = 3M
Jane = 6M
6M+3M+M = 840
10M = 840
M= 84 Pounds
Andre = 3M
Andre = 84*3
Andre has 252 pounds of apples.

The area of the rectangle below is 18 square units. What is the width of the rectangle? Write and solve a division equation to find the width of the rectangle.
Answer:
24/5 or 4 and 4/5
Step-by-step explanation:
3 and 3/4=15/4
18 divided by 15/4=4 and 4/5
4 and 4/5=24/5
24/5 times 15/4=18

Answer:
any number between 83 and 0. [tex]0\leq x\leq 83[/tex]
Step-by-step explanation:
the number 1,548.4484 has the last two digits of 84.
And since the number has to be less than the other number and you can only switch the last two digits in the decimal's place. It has to be less than 84
Hope that helps :)
Answer:
the digit is 4, because that has 4484 but just put 4444

Here's the solution,
figure 1.
by using trigonometry,
=》
[tex] \sin(60) = \dfrac{5 \sqrt{3} }{y} [/tex]
=》
[tex] \dfrac{ \sqrt{3} }{2} = \dfrac{5 \sqrt{3} }{y} [/tex]
=》
[tex] \dfrac{1}{y} = \dfrac{ \sqrt{3} }{2 \times 5 \sqrt{3} } [/tex]
=》
[tex] \dfrac{1}{y} = \dfrac{1}{10} [/tex]
=》
[tex]y = 10[/tex]
And,
=》
[tex] \cos(60) = \dfrac{w}{y} [/tex]
=》
[tex] \dfrac{1}{2} = \dfrac{w}{10} [/tex]
=》
[tex]w = 5[/tex]
So, values are :
y = 10w = 5figure 2.
Since, it's an isosceles triangle, w = y,
So, by pythagoras theorem :
=》
[tex] {w}^{2} + {y}^{2} = (7 \sqrt{2} ) {}^{2} [/tex]
=》
[tex] {w}^{2} + {w}^{2} = 98[/tex]
=》
[tex]2 {w}^{2} = 98[/tex]
=》
[tex] {w}^{2} = 49[/tex]
=》
[tex]w = \sqrt{49} [/tex]
=》
[tex]w = 7[/tex]
and we know, w = y, so their values will be equal to 7 units.

Find x and y
Show all the work
Answer:
x=27°
y=4 units
Step-by-step explanation:
To find x:
The sum of all the angles in a quadrilateral is 360°. In a rhombus (you know it's a rhombus because it's a quatrilateral where all the sides are congruent), opposite angles are congruent. Because you're given that the measure of ∠T is 127°, you also know that m∠V=127°. You also know that m∠U=m∠S=(2x-1)°.
Using this information, set up an equation.
127+127+(2x-1)+(2x-1)=360
You can just divide both sides by 2 to get:
127+(2x-1)=180
Then, just solve for x.
127+2x-1=180
2x+126=180
2x=54
x=27°
To find y:
All the sides are given to be congruent. That's what the little marks on the sides mean, and that's how we knew it was a rhombus earlier.
So SV=VU=UT=TS
SV=6y-5
VU=3y+7
Since SV=VU:
6y-5=3y+7
Solve for y.
3y=12
y=4

Is algebra.
Answer:
B
Step-by-step explanation:
The first one is a binomial. It has two different terms on either side of the middle minus sign. y is raised to the 4 th power so that is degree 4. The answer is b
The second problem is ordered as 4 3 1 2
The powers determine the degree. The terms are all different and the number of terms is determined by the powers of the letters in the terms.

Sam paid $8.28 for 18 stamps. At this rate, how much would it cost Sam to buy 12 stamps?
Answer: $5.52
Step-by-step explanation:
Given: Sam paid $8.28 for 18 stamps.
Thus, the cost of 18 stamps = $8.28
Then the cost of 1 stamp=
Thus, the cost of 1 stamp=$0.46
With the same rate , the cost of 12 stamps=
Therefore, the cost of 12 stamps= $5.52
hence, it costs $5.52 to Sam to buy 12 stamps.
8.28÷18 = 0.46
0.46 is the cost if 1 stamp
cost of 12 stamps= 0.46×12 = $5.52

ZY=√{45²-27²)=36
sin X=ZY/XY=36/45=0.8
Cos X=XZ/XY=27/45=0.6
Tan X= YZ/XZ=36/27=1.33
Angle X and Angle Y are complementary angles. Given Angle Y is equal to 1/5th Angle X. Find the value of Angle X in degrees
Answer:
75 degrees
Step-by-step explanation:
Complementary angles equal 90 degrees together. That is the case with angle X and Y. Set an equation to describe the situation.
Y=1/5X
X=5Y
Now, set another equation:
X+Y=90
Substitute the first equation into the second one.
5Y+Y=90
6Y=90
Y=15
Substitute this once again:
X+15=90
X=75
