A satellite photographs a path on the surface of the Earth that is 600 miles wide. Find the central angle that intercepts an arc 600 miles on the surface of the Earth (radius 3950 miles).
WILL MARK BRAINLIEST
9514 1404 393
Answer:
The central angle is about 8.7°.
Step-by-step explanation:
The relation between angle and arc length is ...
s = rθ
where r is the radius, and θ is the central angle in radians.
600 = 3950·θ
θ = 600/3950 radians = (12/79)(180°/π)
θ ≈ 8.7°

Answer:
Answer : False.
Step-by-step explanation:
Hey there!
The equations of line a and line b are:
line a : y= 5x-6...........(i)
line b : x+5y= 5..........(ii)
Firstly find the slope of both equation.
To find slope of first equation;
y= 5x-6
Comparing the equation with y= mx+c. We get;
Slope (m1) = 5.
Now,
To find slope of second equation;
Slope (m2) = (-coefficient of x)/(coefficient of y)
Slope (m2) = (-1/5)
Therefore, the slope of second equation is -1/5.
As per the condition of parallel lines, slope of 1st equation should be equal to 2nd equation.
Now, comparing their slopes;
5≠(-1/5)
Therefore, the answer is "False".
Hope it helps....
Line A
y=5x-6Compare to slope intercept form
slope=m=5LineB
x+5y=55y=5-xy=1-1/5xSlope
k=-1/5As slopes are negative reciprocal to each other lines are perpendicular to sach other not parallel
Hence it's False
How can i get an equation that shows the relationship below Plz its for a test for tomorrow X. Y. -2. -6 -1. -3 0. 0 1. 3 2. 6
Answer:
x = 3y
Step-by-step explanation:
In tabular form, the variables are given as;
x y
-2 -6
-1 -3
0 0
1 3
2 6
To determine relationships between variables, you observe the numbers and note how they change
In the first instance, the number; -2 changed to -6. This means it was multiplied by 3.
To confirm it, we check the next set of numbers, -1 and -3. This means it is correct.
The equation showing the relationship between both variables is given as;
x = 3y
what is the third side ? due in 2 days
Answer:
the third side could be 8 or 2
Step-by-step explanation:
Answer:
6 < x < 14; answer = 8
Step-by-step explanation:
triangle inequality theorem: sum of any two sides must be greater than the third side
4 + 10 > x x < 14
10 + x > 4 x > 6
Find the value of x.
Answer:
x=6
Step-by-step explanation:
24=4x
divide both by 4
equals 6
Answer:
to find x we have to find the similarly between the smaller and the larger triangle
the two triangle are similar by side angle side(SAS) similarly therom.
we have to see carefully that the two triangle are similar but not congruent.
Step-by-step explanation:
so the bigger triangle is twice big as the smaller.
so 24/4x =2
8x=24
x=24/8
x=3
An eccentric math teacher told his class that he would assign one problem on the first day of school, two
problems on the second day, four problems on the third day, eight problems on the fourth day, and so on. At
this rate, how many problems would he assign on the tenth day? Find a rule that can be used to determine the
number of problems assigned on the nth day.
N is the day it is, so since we are trying to find the number of problems for the 10th day, n will equal 10. The quantity of problems is doubling each day, so you will create this rule:
2^n - 1
Now, to plug in the numbers:
2^10 - 1
Then we simplify:
2^9
And now we solve this equation:
2^9 = 512
The graph shows how a motorboat travels around a lake. What does the graph most likely show?
The speed of the boat increases steadily for 10 minutes and travels at a constant speed after 10 minutes.
Option D is the correct answer.
What is speed?Speed is the ratio of distance and time.
It shows how fast an object is moving at a given time.
We have,
The x-axis can be assumed as 10 minutes for each unit.
Now,
From the graph, we see that the speed is steadily increasing as the time increases from x= 0 to x = 10.
From x = 10, the line on the graph is horizontal this means, the speed is constant.
Thus,
The speed of the boat increases steadily for 10 minutes and travels at a constant speed.

Answer:
Multiply both sides by 3, then subtract 6 from both sides
Step-by-step explanation:
d + 6 / 3 = 6 (multiply both sides by 3)
d + 6 = 18 (subtract 6 from both sides)
d = 12
Answer:
d+6= 18.
d= 12
multiply both sides by 3
subtract 6 from both sides

Answer:

Step-by-step explanation:
Remark
If we draw a line from F to T, we can make a couple of statements.
Call the center of the circle O
1. <FTE = 1/2 the central angle of <FOE. The size of <FOE is the same size as the minor arc. Since The minor arc = 60 degrees, then FTE = 30 degrees.
2. <GTF = 1/2 78 by the same reasoning used above. GTF = 39 because that is 1/2 of 78.
So the answer to the size of <T = 39 + 30 = 69 which is B
There is a much simpler way of doing this.
The central angle of the two arcs is 78 + 60 = 138
The <GTE is 1/2 the central angle
<GTE = 1/2 * 138 = 69
A concession stand at a baseball game sells hot dogs and boxes of popcorn. Justin buys a total of 9 snacks. The number of popcorn boxes he buys is three less than twice as many hot dogs. Which system of equations models this situation if he bought h hot dogs and p boxes of popcorn?
Answer:
}p=3−2h
][
}h=9−p
Step-by-step explanation:
i don't know the steps but i know the answer.
The equation that models the situation is h + p = 9 and 2h - p = 3
EquationLet h represent the number of hot dog snack and p represent the number of popcorn snack.
Justin buys a total of 9 snacks. Hence:
h + p = 9 (1)the popcorn boxes he buys is three less than twice as many hot dogs. Hence:
p = 2h - 32h - p = 3 (2)The equation that models the situation is h + p = 9 and 2h - p = 3

What is the height ?
The height of the rectangular prism will be 9 cm.
What is the volume of the rectangular prism?Let the prism with a length of L, a width of W, and a height of H.
Then the volume of the prism is given as
V = L x W x H
We know that the product of the length and width will be known as the base area.
Then the volume of the rectangular prism will be
V = A x H
Base area = 147 cm²
Volume = 1323 cm³
Then the height of the rectangular prism will be
1323 = 147H
H = 9 cm
The height of the rectangular prism will be 9 cm.

Answer:
Vertex → (2, 4)
Step-by-step explanation:
Quadratic equation has been given as,
y = -x² + 4x
We rewrite this equation in the form of a function as,
f(x) = - x² + 4x
By comparing this equation with the standard quadratic equation,
y = ax² + bx + c
a = -1 and b = 4
Vertex of the parabola represented by this equation is given by [tex][-\frac{b}{2a}, f(\frac{-b}{2a})][/tex]
x coordinate = [tex]-\frac{4}{2(-1)}[/tex]
= 2
y-coordinate = f(2)
= - (2)² + 4(2)
= -4 + 8
= 4
Therefore, vertex of the given function is (2, 4)
