Answer: y-100= 0.25(x-160)
Step-by-step explanation:
Given: Charge per mile = $0.25
Total amount driver pays = $100
Number of miles he drove = 160 miles
Total cost = Flat fee + ( Number of miles he drove) (Charge per mile) ...(i)
i.e. 100= Flat fee + (160)(0.25)
⇒ Flat fee = 100 - (160)(0.25)
If y= total cost , x= number of miles, then
y= ( 100 - (160)(0.25))+ (x)(0.25) [Substitute value of flat fee in (i)]
⇒ y= 100 - (160)(0.25)+ (x)(0.25)
⇒ y-100= (x)(0.25)- (160)(0.25)
⇒ y-100= 0.25(x-160)
Hence, the required equation: y-100= 0.25(x-160)
what is the answer for 7(x+2) = 6(x+1)
Answer:
x= -8
Step-by-step explanation:
Simple math
Answer: x = -8
7(x + 2) = 6(x + 1)
⇔ 7x + 14 = 6x + 6
⇔ 7x - 6x = 6 - 14
⇔ x = -8

Step-by-step explanation:
You are at a parade looking up at a large balloon floating directly above the street. You are 60 feet from a point on the street directly beneath the baloon. To see the top of the baloon, you look up at an angle of 53°. To see the bottom of the ballon you look up at an an angle of 29°. Estiamte the height, h, of the balloon to the nearest foot. Answer with only the numeric value
Answer:
The height of the balloon is 46 feet.
Step-by-step explanation:
Let the height from the ground to the top of the balloon be represented by x. Applying the appropriate trigonometric function, we have;
Looking at the top of the balloon,
Tan θ = [tex]\frac{opposite}{adjacent}[/tex]
Tan 53° = [tex]\frac{x}{60}[/tex]
x = 60 x Tan 53°
= 79.6227
x = 79.62 feet
Looking at the bottom of the balloon, let the height from the ground to the bottom of the balloon be represented by y.
Tan θ = [tex]\frac{opposite}{adjacent}[/tex]
Tan 29° = [tex]\frac{y}{60}[/tex]
y = 60 x Tan 29°
= 33.2585
y = 33.26 feet
The height of the balloon = x - y
= 79.6227 - 33.2585
= 46.3642
The height of the balloon is 46 feet.

I NEED HELP ASAP, WILL MARK BRAINLIEST Find the value of y. Round to the nearest tenths place.
Answer:
Side a = 1
Side b = 0.5
Side c = 0.86603 = √3/2
Nearest tenths is 0.9
Step-by-step explanation:
The following is one way to perform the calculation. It may not be the best way.
Calculates 2 sides based on 3 given angles and 1 side.
b = a·sin(B)/sin(A) = 0.5
c = a·sin(C)/sin(A) = 0.86603 = √3/2
Area =
ab·sin(C)
2
= 0.21651
Perimeter p = a + b + c = 2.36603
Semiperimeter s =
a + b +c
2
= 1.18301
Height ha =
2×Area
a
= 0.43301
Height hb =
2×Area
b
= 0.86603
Height hc =
2×Area
c
= 0.5
Median ma = √(a/2)2 + c2 - ac·cos(B) = 0.5
Median mb = √(b/2)2 + a2 - ab·cos(C) = 0.90139
Median mc = √(c/2)2 + b2 - bc·cos(A) = 0.66144
Inradius r =

i rlly need help; finding angles
Answer:
1=35 find angle 2 80+65-180=35
2= 65 vertical angles are congruent ex 115-180
3=29 ex. 90+65-180=29
4= 115 vertical angle congruent
5=65 vertical angles are congruent ex 115-180
6=65 35+80-180=65
7=144
Answer:
∠1 = 35 ; ∠2 = 65 ; ∠3 = 29 ; ∠4 = 115
∠5 = 65 ; ∠6 = 36 ; ∠7 = 144
Step-by-step explanation:
∠4 = 115 {Vertically opposite angles}
∠5 + 115 = 180 {linear pair}
∠5 = 180 - 115
∠5 = 65
∠2 = ∠5 {Vertically opposite angles}
∠2 = 65
∠1 + 80 +∠2 = 180 {Angle sum property of triangle}
∠1 + 80 + 65=180
∠1 + 145 = 180
∠1 = 180 - 145
∠1 = 35
∠5 + ∠7 + 90 + 61 = 360 {angle sum property of quadrilateral}
65 + ∠ 7 + 90 + 61 = 360
∠7 + 216 = 360
∠7 = 360 - 216
∠7 = 144
∠6 + ∠ 7 = 180 {linear pair}
∠6 + 144 = 180
∠6 = 180 - 144
∠6 = 36
∠3 + ∠4 +∠ 6 = 180 {angle sum property of triangle}
∠3 + 115 + 36 = 180
∠3 + 151 = 180
∠3 = 180 - 151
∠3 = 29

Which of the following equations have exactly one solution?
Choose all answers that apply:
(Choice A)
-19x + 18 = -19x + 18
(Choice B)
-19x -18 = -19x + 18
(Choice C)
19x + 18 = -19x + 18
(Choice D)
19x - 18 = -19x + 18
Answer:
Option C and Option D have exactly one solution.
Step-by-step explanation:
The equation will have exactly one solution when it completely solves and we get value of x.
Checking all choices
(Choice A)
-19x + 18 = -19x + 18
-19x+19x=18-18
0=0
(infinite solutions)
(Choice B)
-19x -18 = -19x + 18
-19x+19x=18+18
0≠36
(no solution)
(Choice C)
19x + 18 = -19x + 18
19x+19x=18-18
38x=0
x=0
(One solution)
(Choice D)
19x - 18 = -19x + 18
19x+19x=18+18
38x=36
x=36/38
x=18/19
(One solution)
So, Option C and Option D have exactly one solution.

Acme is selling a 6 pound turkey for $25.50.
Write the rate
What is the unit rate
Answer:
$4.25 each pound
Step-by-step explanation:
To find the unit rate you want to divide the price by the pound
25.50 / 6 = 4.25
Therefore it's $4.25 each pound which is the unit rate

Which statement is a valid claim that could be made using the data in the graph?
Directional selection is occurring because the graph favors an extreme.
Stabilizing selection is occurring because the average is favored.
Disruptive selection is occurring because the two extremes are favored.
Biodiversity variation is occurring because there is an increase in trait variation.
Stabilizing selection is occurring because the average is favored.
If its the same graph im thinking of.
The correct statement is a valid claim that could be made using the data in the graph is,
B) Stabilizing selection is occurring because the average is favored.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Now, On this graph we can observe the workings of the stabilizing selection.
Since, Stabilizing selection tends to favor the average phenotype and eliminate the extremes.
Essentially, this means that the natural selection is selecting the mean value of a trait as optimal.
Hence, In our case, the mean weight of newborns is selected as optimal, because newborns born with less weight can be too weak to survive and the ones that have too much weight (are too big) can hurt the mother during birth.
Thus, The correct statement is a valid claim that could be made using the data in the graph is,
B) Stabilizing selection is occurring because the average is favored.

A soccer field is a rectangle 90 meters wide and 120 meters long. The coach asks the players to run from one corner to the other corner across the middle of the field.
Answer:
And the question is???
Answer:
Step-by-step explanation:
use the pythagorean therom:
a^2 + b^2 = c^2
substitute in your values
90^2 +120^2=c^2
multiply
8100+14400=c^2
add
22500=c^2
take the square root of both sides
c= 150 meters :)
