From an airplane at an altitude of 1700 m, the angle of depression to a rock on the ground measures 25 degrees. Find the distance from the plane to the rock. Give your answer correct to 1 dp.
help me plz
Answer:
3,645.7mStep-by-step explanation:
The set up will give a right angled triangle;
altitude (opposite side ) = 1700m
angle of depression = 25degrees
Required
distance from the plane to the rock (adjacent side)
Using the SOH, CAH, TOA identity;
According to TOA
tan 25 = opposite/adjacent
tan25 = 1700/adj
adj = 1700/tan 25
adj = 1700/0.4663
adj = 3,645.72m
Hence the distance from the plane to the rock to 1 dp is 3,645.7m
Given that the two parallel lines are cut by a transversal, and the measure of angle 2 is 50 degrees. Find each of the missing angles.
Answer:
Step-by-step explanation:
Lines m and l are the parallel lines and a line 'n' is a transverse intersecting these lines.
m∠2 = 50°
m∠1 + m∠2 = 180° [Linear pair of angles]
m∠1 = 180° - 50°
m∠1 = 130°
m∠3 = m∠1 = 130° [Vertically opposite angles]
m∠3 + m∠5 = 180° [Consecutive interior angles]
m∠5 = 180° - m∠3
= 180° - 130°
= 50°
m∠6 + m∠5 = 180° [Linear pair of angles]
m∠6 = 180° - 50° = 130°
From the given diagram
angle 1= 130 degrees
Angle 3 = 130 degree
Angle 5= 50 degree
Angle 6= 130 degree
Given :
the two parallel lines are cut by a transversal
Angle 1 and angle 2 are linear pair of angles
Sum of angle 1 and angle 2 is 180
[tex]<1+<2=180\\<1+50=180\\<1=180-50\\<1= 130[/tex]
Angle 1 and angle 3 are vertical opposite angles
They are equal
[tex]<1=<3\\130=<3\\<3= 130[/tex]
When two parallel lines are cut by transversal , corresponding angles are equal
<5= <2
<5=50
Alternate exterior angles are congruent
<6=<1
<6=130
angle 1= 130 degrees
Angle 3 = 130 degree
Angle 5= 50 degree
Angle 6= 130 degree

Edwin graphs the relationship of the gallons of milk he buys in terms of dollars.
Sam buys milk from a different shop. He writes an equation for the amount he spends on milk, p = 3.4g, where p is the cost and g is the gallons of milk bought. Who buys milk at a lower rate, and what is the price?
A) Edwin buys milk at a lower rate, $3.40 per gallon.
B) Edwin buys milk at a lower rate, $3.50 per gallon.
C) Sam buys milk at a lower rate, $3.50 per gallon.
D) Sam buys milk at a lower rate, $3.40 per gallon.
Answer:
the answer is d) sam buys milk at $3.40 per gallon
Step-by-step explanation:
the graph shows that edwin spends $7 for 2 gallons
meaning that per gallon, he spends 3.50
meanwhile, the equation sam gives us shows that the unit price is 3.40 for him... since p=price and g=gallons
or if you wanted it to look at it graphically
Edwins slope is 3.50
sam's is 3.40

2y -10=22
(WORTH 10 POINTS)
Answer:
y = 16
Step-by-step explanation:
2y - 10 = 22
+10 +10
----------------------
2y = 32
÷2 ÷2
----------------
y = 16
Check your work by plugging 16 in for y
2(16) - 10 = 22
2(16) = 32 - 10 = 22

The fare for a taxi cab is $2.75 per passenger and $0.50 for each mile. A group of friends has $22.00 for cab
fare. Write a linear inequality to represent how many miles, y, the group can travel if there are x people in
the group
The inequality is ?
Answer:
2.75x+0.5y<22
Step-by-step explanation:
The price for the amount of friends would be 2.75 times the amount of people. Since we don't know that value, we use x.
The price for the distance would be 0.5 (which is equivalent to 0.50) times the amount of miles. Since we don't know that value, we use y.
We add the amount of friends and the distance amount together with an addition sign, and then we choose out inequality sign. The friends only have 22 dollars, so that is the max they can go. We put a line under the < because it can be equal to 22.
I hope this helps!

(3,4) and (12,19) find the equation of the line that passes through it
Answer:
The equation of the line will be:
[tex]y=\frac{5}{3}x-1[/tex]
Step-by-step explanation:
Given the points
(3, 4)(12, 9)Finding the slope between (3, 4) and (12, 9)
[tex]\left(x_1,\:y_1\right)=\left(3,\:4\right),\:\left(x_2,\:y_2\right)=\left(12,\:19\right)[/tex]
[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{19-4}{12-3}[/tex]
[tex]m=\frac{5}{3}[/tex]
The equation of the line can be obtained using the point-slope form of the equation of the line
[tex]y-y_1=m\left(x-x_1\right)[/tex]
substituting the values m = 5/9 and the point (3, 4)
[tex]y-4=\frac{5}{3}\left(x-3\right)[/tex]
[tex]y-4+4=\frac{5}{3}\left(x-3\right)+4[/tex]
[tex]y=\frac{5}{3}x-1[/tex]
Therefore, the equation of the line will be:
[tex]y=\frac{5}{3}x-1[/tex]

A lifeguard earns $320 per week for working 40 hours plus $12 per hour worked over 40 hours. A lifeguard can work a maximum of 60 hours per week.
Which graph above best represents the lifeguard’s weekly earnings in dollars for working h hours over 40?
A) Answer choice F
B) Answer choice G
C) Answer choice H
D) Answer choice J
Answer:
Its G
Step-by-step explanation:
they can only work 60 hours so 320 +240 is 560 so it matches the graph
Graph G is the suitable graph to represent the lifeguard's weekly earnings in dollars for working more over 40 hours per week.
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
Given that a lifeguard makes $320 per week for 40 hours worked, plus $12 per hour worked after 40 hours. A lifeguard can work no more than 60 hours each week.
For more than 40 hours of labor, the graph on the y-axis will begin at the point (0, 320). Given that the lifeguard is paid $12 per hour, we must choose the graph with the highest slope.
Slope of graph F = (400 - 320)/(10 - 0) = 80/10 = 8
Now, slope of graph G = (500 - 320)/(15 - 0) = 180/15 = 12
Thus, graph G is the correct option.

a tornado traveled 260 miles in 4 hours. if the average rate at wich the tornado is moving slows by 20% how many miles will the tornado travel in the next 2 hours
Answer:104
Step-by-step explanation:
So you would take 260 miles and divide by 4 hours to get 65 mph. And since the rate slows by 20%, you would subtract 13 from 65 giving you 52. So the new speed of the tornado is 52 mph. And take that and multiply it by 2 hours to get 104 miles.
Angles A and B are adjacent angles and are supplementary. The measure of ∠A is (2x+5)∘ and the measure of ∠B is (4x+25)∘. Question 1 Part A Write an equation that can be used to determine the value of x. Enter the correct answer in the box.
Answer:
Part A
This equation is given as
180° = ∠A + ∠B
180° = (2x+5)° + (4x+25)°
Part B
The value of x = 25°
Step-by-step explanation:
We are told in the question that:
Angles A and B are adjacent angles and are supplementary. The measure of ∠A is (2x+5)∘ and the measure of ∠B is (4x+25)∘.
Question 1 Part A Write an equation that can be used to determine the value of x.
Two angles are called supplementary when their measures add up to 180 degrees.
This equation is given as
180° = ∠A + ∠B
180° = (2x+5)° + (4x+25)°
Part B
Solving the equation
180° = (2x+5)° + (4x+25)°
180° = 2x + 5 + 4x + 25
180° = 6x + 30
Collect like terms
180° - 30° = 6x
150° = 6x
x = 150/6
x = 25°

A dressmaker needs to cut 18-inch pieces of ribbon from rolls of ribbon that
are 12 feet in length. How many 18-inch pieces can the dressmaker cut from
10 of these rolls of ribbon?
Answer:
80 pieces
Step-by-step explanation:
12 ft x 12 in = 144 inches
144 in x 10 rolls = 1,440 inches
1,440 in / 18 in = 80 pieces of ribbons

Janelli and her best friend Cameron go shopping the function P parentheses X equals X exponent for subtract 3X exponent 3+ 2X exclamation at 2+24 represents how much money each girl spent based on the number of hours they were shopping if Jenny and Cameron go shopping for two hours how much money did they spent together
Answer:
$176
Step-by-step explanation:
Janelle and her best friend Carmen go shopping. the function p(t) = 5x^4 - 3x^3 + 2x^2 + 24 represents how much money each girl spent based on the number of hours they were shopping. If Janelle and Carmen each go shopping for 2 hours how much money did they spend together.
$58
$62
$176
$124
p(t) = 5x^4 - 3x^3 + 2x^2 + 24
Solve when x = 2 hours
p(t) = 5x^4 - 3x^3 + 2x^2 + 24
= 5(2)^4 - 3(2)^3 + 2(2)^2 + 24
= 5(16) - 3(8) + 2(4) + 24
= 80 - 24 + 8 + 24
= $88
how much money did they spent together?
= $88 × 2
= $176
They both spent $176 altogether
