Answer:
You and your friend are 1.797 miles apart. Since east and west are opposite directions, we just add the distances.
Step-by-step explanation:
They are walking on opposite directions, so to see how far apart, we add how much each of you walked.
We have that:
You walk 1.237 miles west.
He walks 0.56 miles.
1.237 + 0.56 = 1.797.
You and your friend are 1.797 miles apart. Since east and west are opposite directions, we just add the distances.

Write the explicit formula for the sequence.
2, 4, 6, 8, 10, ...
Answer:
a(n) = 2 + 2(n - 1)
Step-by-step explanation:
Since each new term is derived from the previous term by adding 2, this is an arithmetic sequence, and the "common difference" is 2.
Then a(n) = 2 + 2(n - 1)
100 PTS:Please help me now plz plz
Answer:
x = 12
Step-by-step explanation:
We have a right triangle with hypotenuse 10 and the height 8. Either the one on the left or the one on the right
We can find the base using the Pythagorean theorem
a^2 + b^2 = c^2
a^2 +8^2 = 10^2
a^2 +64 = 100
Subtract 64 from each side
a^2 = 100 -64
a^2 = 36
Take the square root of each side
a = 6
Now a is 1/2 of the total base of the big triangle. It is identical since the triangles are equal
x = 2 * a
x = 2*6 = 12
Answer:
x = 12
Step-by-step explanation:
Consider the right angle triangle with
base: x/2
height: 8
hypotenuse: 10
Using pythagoras theorem
10² = 8² + (x/2)²
(x/2)² = 100 - 64
(x/2)² = 36
x/2 = 6
x = 12

[tex](x^a)^6=\dfrac{1}{x^{30}} \\\\(x^{-7})^{-4}=x^b\\\\(x^{-2})^c=x^{22}[/tex]
Answer:
a=-5, b=28 c=-11Step-by-step explanation:
To solve for a,b and c, we apply the following laws of indices
[tex]\dfrac{1}{p^m}=p^{-m} \\\\(a^m)^n=a^{m X n}\\\\$If p^m=p^n,$ then m=n[/tex]
Therefore :
Part 1
[tex](x^a)^6=\dfrac{1}{x^{30}}\\\\x^{a*6}=x^{-30}\\6a=-30\\$Divide both sides by 6\\a=-5[/tex]
Part 2
To solve for b
[tex](x^{-7})^{-4}=x^b\\x^{-7*-4}=x^b\\x^{28}=x^b\\$Since they have the same base\\b=28[/tex]
Part 3
To solve for c
[tex](x^{-2})^c=x^{22}\\x^{-2*c}=x^{22}\\$Just as in part 2, the two sides of the equality have the same base, therefore:\\-2c=22\\Divide both sides by -2\\c=-11[/tex]

The formula for height, in feet of a projectile under the influence of gravity is given by h=-16t^2+vt+s, where t is the time in seconds, v is the upward velocity at the start, and s is the starting height. Marvin throws a baseball straight up into the air at 70 feet per second. The ball leaves his hand at a height of 5 feet. When does the ball reach a height of 75 feet?
Answer:
1.55s
Step-by-step explanation:
The height equation of the projectile is given as;
h = -16t^2 + vt + s .......1
where;
t is the time in seconds,
v is the upward velocity at the start,
s is the starting height.
Given;
v = 70 ft/s
s = 5 ft
Substituting the values equation 1 becomes;
h = -16t^2 + 70t + 5
For the ball to reach 75 ft, h = 0
75 = -16t^2 + 70t + 5
-16t^2 + 70t + 5 - 75 = 0
-16t^2 + 70t - 70 = 0
solving the quadratic equation;
Time t = 2.83 s and t = 1.55s
Therefore, the ball will first reach 75 ft after 1.55 seconds.

Two boats started to move towards each other from two boat stations, located 30 miles apart. One boat moved at a speed of 3 miles per hour, the other moved twice as fast. How soon will the boats meet?
Answer:
The boats will meet in 3.33 hours.
Step-by-step explanation:
The position of each boat can be modeled by a first order equation.
I am going to say that the first boat is at the position 0, and moving in the positive direction with a speed of 3 miles per hour. So
[tex]A(t) = 0 + 3t[/tex]
They are moving in oppositie directions, and initially are 30 miles apart. This means that the second boat starts at the position 30, and moves in the negative direction at the rate of 6 miles an hour. So
[tex]B(t) = 30 - 6t[/tex]
How soon will the boats meet?
This is t when:
[tex]A(t) = B(t)[/tex]
[tex]3t = 30 - 6t[/tex]
[tex]9t = 30[/tex]
[tex]t = \frac{30}{9}[/tex]
[tex]t = 3.33[/tex]
The boats will meet in 3.33 hours.

There were the most observations of female tokoeka kiwis in the given frequency table so option (A) will be correct.
What is a frequency table?A frequency table is a list of objects with the frequency of each item shown in the table.
The frequency of an occurrence or a value is the number of times it happens.
Given the frequency table of kiwi birds with their gender.
Number of female tokoeka kiwis = 44
Now if we look at the table there is none of any bird that is greater than 44 which means it is the most observations in the research.
Hence "There were the most observations of female tokoeka kiwis".

Answer:
The area of this circle is [tex]176.74cm^2[/tex]
Step-by-step explanation:
The formula for the area of a circle is : [tex]\pi *radius^2[/tex]
The radius is the length from one side of the circle to the centre.
To work this out you would simply multiply pi by the radius of 7.5. squared. This gives you 176.74.

Can adjacent angles be complementary?
Give a brief explanation as to why or why not.
Answer:
Two adjacent angles can be complementary
Step-by-step explanation:
if they add up to 90°. For example, a diagonal of a square will split the right angle into two equal angles; 45°+45°. In a right triangle, the altitude from a right angled vertex will split the right angle into two adjacent angles; 30°+60°, 40°+50°, etc.

Brianna and Ava go to the movie theater and purchase refreshments for their friends. Brianna spends a total of $39.00 on 2 bags of popcorn and 2 drinks. Ava spends a total of $174.50 on 8 bags of popcorn and 10 drinks. Write a system of equations that can be used to find the price of one bag of popcorn and the price of one drink. Using these equations, determine and state the price of a drink, to the nearest cent.
Answer:
2p + 2d = 39 ____________(1)
8p + 10d = 174.50 _________(2)
Price of one drink is $9.25
Step-by-step explanation:
Let the price of a bag of popcorn be p.
Let the price of a drink be d.
Brianna spends a total of $39.00 on 2 bags of popcorn and 2 drinks. This implies that:
2p + 2d = 39 ____________(1)
Ava spends a total of $174.50 on 8 bags of popcorn and 10 drinks. This implies that:
8p + 10d = 174.50 _________(2)
We now have two system of equations which we can use to find the price of a bag of popcorn and drink:
2p + 2d = 39 ____________(1)
8p + 10d = 174.50 _________(2)
Multiply (1) by 4 subtract from (2):
8p + 10d = 174.50 _______(2)
- 8p + 8d = 156 __________(1)
2d = 18.50
=> d = $9.25
The price of one drink is $9.25
Based on the data given in the picture, calculate the area of the car track...
Please, I need help, i will mark the answer with a brainliest mark...
Refer to the diagram below. We need to find the areas of the green and blue regions, then subtract to get the area of the orange track only.
The larger green region is composed of a rectangle of dimensions 200 meters by 4+42+4 = 50 meters, along with two semicircles that combine to make a full circle. This circle has radius 25 meters.
The green rectangle has area 200*50 = 10000 square meters. The green semicircles combine to form an area of pi*r^2 = pi*25^2 = 625pi square meters. In total, the full green area is 10000+625pi square meters. I'm leaving things in terms of pi for now. The approximation will come later.
The blue area is the same story, but smaller dimensions. The blue rectangle has dimensions 200 meters by 42 meters, so its area is 200*42 = 8400 square meters. The blue semicircular pieces combine to a circle with area pi*r^2 = pi*21^2 = 441pi square meters. In total, the blue region has area 8400+441pi square meters.
After we figure out the green and blue areas, we subtract to get the orange region's area, which is the area of the track only.
orange area = (green) - (blue)
track area = (10000+625pi) - (8400+441pi)
track area = 10000+625pi - 8400-441pi
track area = (10000-8400) + (625pi - 441pi)
track area = 184pi + 1600 is the exact area in terms of pi
track area = 2178.05304826052 is the approximate area when you use the pi constant built into your calculator. If you use pi = 3.14 instead, then you'll get 2177.76 as the approximate answer. I think its better to use the more accurate version of pi. Of course, be sure to listen/follow your teachers instructions.
The measure of a straight angle (2x+50) (6x+2)
Answer:
see below
Step-by-step explanation:
If the two angles form a straight angle, their sum is 180
2x+50 + 6x+2 = 180
Combine like terms
8x +52 = 180
Subtract 52 from each side
8x+52-52 = 180-52
8x =128
divide each side by 8
8x/8 = 128/8
x =16
2x+50 = 2(16)+50 = 32+50 = 82
6x+2 = 6(16)+2 =96+2 = 98
