Question: Meghan has created a diagram of her city with her house, school, store, and gym identified. A. How far is it from the gym to the store? B. Meghan also wants to walk to get some exercise, rather than going to the gym. She decides to walk along arc AB. How far will she walk? Round to 3 decimal places.
Answer:
a). Distance between the gym and store 9.25 m
b). Meghan will walk 5.637 m along the arc AB.
Step-by-step explanation:
a). Theorem of intersecting chords inside the circle,
When two chords intersect each other in a circle multiplication of their segments are equal.
3×7 = 4a
a = [tex]\frac{21}{4}[/tex]
a = 5.25 m
Distance between the gym and store = 4 + 5.25
= 9.25 m
b). Length of an arc = [tex]\frac{\theta}{360}\times (2\pi r)[/tex]
[tex]\widehat{AB}[/tex] = [tex]\frac{64.6}{360}\times 2\pi (5)[/tex]
= [tex]\frac{646\pi }{360}[/tex]
= 5.6374 m
≈ 5.637 m
Therefore, Meghan will walk 5.637 m along the arc AB.

6-5 solving rational equations 8/x+3=1/x+1
Answer:
x = -5/7
Step-by-step explanation:
8/(x+3)=1/(x+1)
Using cross products
8*(x+1) = 1*(x+3)
Distribute
8x+8 = x+3
Subtract x from each side
8x-x +8 = x+3-x
7x +8 =3
Subtract 8 from each side
7x+8-8 = 3-8
7x = -5
Divide by 7
7x/7 = -5/7
x = -5/7

L'(–2, 1), M'(–3, 5), and N'(–6,4)
L'(–1, 2), M'(–5, 3), and N'(–4,6)
L'(2, 1), M'(3, 5), and N'(6,4)
Answer:
fourth option
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y), thus
L(2, - 1 ) → L'(2, 1 )
M(3, - 5 ) → M'(3, 5 )
N(6, - 4 ) → N'(6, 4 )

Determine the value of x in the figure. answers: A) x = 9 B) x = 6 C) x = 4.5 D) x = 3
Answer:
D
Step-by-step explanation:
The marks through each of the sides of the triangle denote that all of the side lengths of the triangle are equal, or that it is an equilateral triangle. Therefore:
7x+9=x+27
6x+9=27
6x=18
x=3
Therefore, the correct answer is choice D. Hope this helps!
Answer:
x=3
Step-by-step explanation:
The sides are the same length
x+27 = 7x+9
Subtract x from each side
x+27-x = 7x-x+9
27 = 6x+9
Subtract 9 from each side
27-9 = 6x
18 = 6x
Divide by 6
18/6 = 6x/6
3 =x
The distance between city A and city B is 22 miles. The distance between city B and city C is 54 miles. The distance betweeb city A and city C is 51 miles. What type of trianglr is created by the three cities?
Answer:
the triangle is an obtuse
Step-by-step explanation:
draw it out
Answer: Acute Triangle
Step-by-step explanation:
54 is the hypotenuse because it is the longest side.
Square all of the sides.
So
54^2=2916
51^2=2601
22^2=484
Now you have 2916=2601+484
Add the two on the right and they will be greater than 2916.
Because of that, you will have an acute triangle because 22^2+51^2>54^2

What is Geometric Progression?A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.
The nth term of a GP is aₙ = arⁿ⁻¹
The general form of a GP is a, ar, ar2, ar3 and so on
Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )
Given data ,
Let the geometric progression be represented as A
Now , the value of A is
A = -200 , -300 , -450 , -675 ...
The common ratio of the GP = second term / first term
On simplifying , we get
r = -300 / -200
r = 3/2
r = 1.5
Therefore , each term is 1.5 times the previous term
Hence , the GP is solved

A train travels at a speed of 45 kmph. In 48 minutes, how much distance will it travel? ( with explanation )
Answer:
36 km
Step-by-step explanation:
By dividing 45 by 60 you make it into .75 per minute therefore by multiplying by 48 you get your answer which is 36 km
Answer:
36 km
Step-by-step explanation:
We are given a speed in km per hour. Since 1 hour = 60 minutes, we can find the speed in km per minute.
45 kph = 45 km/hour = 45 km/(60 minutes) = 0.75 km/minute
Now that we know the speed in km per minute, we multiply the speed by 48 minutes to find the distance traveled in 48 minutes.
0.75 km/minute * 48 minutes = 36 km
Which statement justifies that ∠K ≅ ∠N? answers: A) ΔHKL ≅ ΔHMN by ASA; but the two angles aren't congruent because they aren't corresponding angles. B) The two angles aren't congruent. C) ΔHKL ≅ ΔHMN by ASA; ∠K ≅ ∠N because they're corresponding angles in congruent triangles. D) ΔHLK ≅ ΔHMN by AAS; ∠K ≅ ∠N because they're corresponding angles in congruent triangles.
Answer:
Correct answer is:
D) ΔHLK ≅ ΔHMN by AAS; ∠K ≅ ∠N because they're corresponding angles in congruent triangles.
Step-by-step explanation:
We are given the diagram, in which there are 2 triangles namely [tex]\triangle HLK, \triangle HMN[/tex].
1. Side KH = Side NH
2. [tex]\angle L \cong \angle M[/tex]
From the given figure, we can derive that:
[tex]\angle KHL \cong \angle NHM[/tex]
Property used: Vertically opposite angels made by two lines crossing each other are equal.
So, we have two angles ([tex]\angle L \cong \angle M[/tex] and [tex]\angle KHL \cong \angle NHM[/tex])of the triangle as same and one side equal from the two given triangles [tex]\triangle HLK, \triangle HMN[/tex].
So, we can say that the two triangles are congruent.
[tex]\triangle HLK \cong \triangle HMN[/tex]
The side is not between the two equal angles, so it is AAS congruence.
And Congruent triangles have their corresponding angles equal.
Therefore, option D) is true :
ΔHLK ≅ ΔHMN by AAS; ∠K ≅ ∠N, because they're corresponding angles in congruent triangles.
Answer:
ΔHLK ≅ ΔHMN by AAS; ∠K ≅ ∠N because they're corresponding angles in congruent triangles.

3 Euros can be exchanged for 22.41 Kroners. How many Euros can be exchanged for 100 Kroners?
Answer:
13.39 Euros
Step-by-step explanation:
The ratio between Euros and Kroners is 3:22.41. This means for every 3 Euros we get 22.41 Kroners. This also means for every Euro we get 22.41/3 = 7.47 Kroners. To calculate the number of Euros that can be exchanged for 100 Kroners, we simply divide 100 Kroners by our conversion factor. 100/7.47 = 13.3868809

A ball is kicked off the ground with a velocity of 15 m/s at an angle of 30° horizontally. What is the horizontal distance the ball travels before returning to the ground?
a.15.5 m
b.17.5 m
c.19.5 m
d.21.5 m
Answer:
The horizontal distance the ball travels before returning to the ground is 19.5 m
Step-by-step explanation:
Formula of range of horizontal distance =[tex]\frac{u^2 Sin 2 \theta}{g}[/tex]
Where u is the initial velocity
g is gravity
We are given that A ball is kicked off the ground with a velocity of 15 m/s at an angle of 30° horizontally.
So, u = 15 m/s
[tex]\theta = 30^{\circ}[/tex]
g = 10
So, the horizontal distance the ball travels before returning to the ground = [tex]\frac{15^2 Sin 2(30^{\circ})}{10}=19.48 \sim 19.5 m[/tex]
Hence The horizontal distance the ball travels before returning to the ground is 19.5 m
A group of friends buys 15 movie tickets for a total of $147.66, which
includes a 7% sales tax.
Before tax, how much did a single movie ticket cost?
Answer: $9.20
Step-by-step explanation:
Divide the full tax price by the sales tax (7% or .07) plus 1 (always add 1 to the tax) thus
$147.66 / 1.07 = $138.00
So $138.00 is the full price without tax.
Now divide $138.00 by the amount of tickets (15) to find a single ticket price before tax!
138.00/15 = $9.20
Remember to always add 1 to the tax percentage above when dividing to get the *pre-tax* price.
