Two hikers are 22 miles apart and walking toward each other. They meet in 4 hours. Find the rate of each hiker if one hiker walks 1.1 mph faster than the other
The speed of the slow hiker is mph, and the speed of the fast hiker is mph.
Step-by-step explanation:
Since, the hiker are walking at different speeds they meet at a point not in the middle.
Let distance travelled by Hiker A (slower) be x at speed s.
So, distance travelled by Hiker B (faster) is (22 - x) at a speed (s + 1.1) .
[tex]speed \: = \frac{distance}{time} [/tex]
s = x / 4s + 1.1 = 22 - x / 4Solving equations 1 and 2, we get :
x = 8.8m and s = 2.2mph
Therefore,
Speed of Hiker A = 2.2 mph
Speed of Hiker A = 2.2 mphSpeed of Hiker B = 3.3 mph
6=1-2n+5 can you please solve it
Answer:
n = 0
Step-by-step explanation:
6 = 1 - 2n + 5
6 = 6 -2n
0 = -2n
n = 0
The value of n after solving the given equation 6 = 1 - 2n + 5 is the number, n = 0.
Given an equation:
6 = 1 - 2n + 5
It is required to find the value of n.
In order to find the value of n, the variable n has to be isolated to one side of the equation with the constant on the other.
Here, the variable is n.
The equation can be written as:
6 = -2n + 6
Subtract 6 from both sides.
0 = -2n
Now, divide both sides by -2.
0 = n
Hence, the value of n is 0.

In the past month, each person showered for an average of 480 480480 minutes and used an average 72 7272 liters of shower water (over the entire month). Water costs 0.20 0.200, point, 20 dollars per liter. How much did Trevor's family pay per minute on shower water?
Answer:
The amount Trevor's family pay per minute on shower water is $0.005.
Step-by-step explanation:
The cost of water is,
Cost = $0.20/liter
Amount of water used over the entire month:
Amount of water used = 72 liters
Compute the total water cost as follows:
Total water cost = Amount of water used × Cost
= 72 × 0.20
= $14.4/liter
The average number of minutes each person showered is:
Average number of minutes = 480 minutes.
The number of people in Trevor's house:
N = 6
Compute the total amount of time the 6 person showered as follows:
Total amount of time = Average number of minutes × N
= 480 × 6

apples, went to market and sold all their apples at the same price, and each
received the same sum of money. What was the price?
Answer:
The amount each took home was 20 unit currency.
Step-by-step explanation:
We are given that Seven apple women, possessing respectively 20, 40, 60, 80, 100, 120, and 140 apples, went to market and sold all their apples at the same price, and each received the same sum of money.
Formula : [tex]a \times n + (n - 1)[/tex], [tex](a + b)\cdot n + (n - 2)[/tex], [tex](a + 2 \cdot b) \cdot n + (n - 3)[/tex], [tex](a + 3 \cdot b) \cdot n + (n - 4)[/tex], [tex](a + 4 \cdot b) \cdot n + (n - 5)[/tex], [tex](a + 5 \cdot b) \cdot n + (n - 6)[/tex], [tex](a + 6 \cdot b) \cdot n + (n - 7)[/tex]
[tex]a \cdot n + (n - 1) = 20[/tex]
[tex](a + b) \cdot n + (n - 2)=40[/tex]
[tex](a + 2 \cdot b) \cdot n + (n - 3) = 60[/tex]
[tex](a + 3 \cdot b) \cdot n + (n - 4) = 80[/tex]
[tex](a + 4 \cdot b) \cdot n + (n - 5) = 100[/tex]
[tex](a + 5 \cdot b) \cdot n + (n - 6) = 120[/tex]
[tex](a + 6 \cdot b) \cdot n + (n - 7) = 140[/tex]
On solving :
n = 7, a = 2, b = 3
So,
[tex]2 \times 7 + 6 = 20[/tex]
[tex]5 \times 7 + 5=40[/tex]
[tex]8 \times 7 + 4 = 60[/tex]
[tex]11 \times 7 + 3 = 80[/tex]
[tex]14 \times 7 + 2 = 100[/tex]
[tex]17 \times 7 + 1 = 120[/tex]
Based on market pricing if groups of apples are sold at 1 unit currency for 7, and extras are sold for 3 unit currency per extra 1, we have the amount :
2×1 + 6×3 = 20
5×1 + 5×3=20
8×1 + 4×3 = 20
11×1 + 3×3 = 20
14×1 + 2×3 = 20
17×1 + 1×3 = 20
20×1 = 20
Therefore, the amount each took home was 20 unit currency.

The cost of a cell phone is $700. According to the cellular device contract, you will need to be $0.22 per minute for first 500. Write the function that models the total cost of the cell phone bill for the first 500 min. What is the domain of the function?
Answer:
[tex]C = 700+0.22m[/tex]
Domain is [0,500] or [tex]0 \leq m\leq 500[/tex]
Step-by-step explanation:
We are given that:
Cost of cell phone is $700.
Cost per minute for the first 500 calls is $0.22 per minute.
To find:
Function to model total cost of the cell phone bill for the first 500 minutes.
And domain of the function = ?
Solution:
Here, Total Cost is the sum of cost of cell phone, plus the cost of calls.
Total Cost = Cost of cell Phone + Cost of calls
We have the cost of cell phone as $700.
and cost of calls is $0.22 per minute up to 500 minutes.
Let the number of minutes for the calls is m. (m [tex]\leq[/tex] 500)
So, cost for m number of minutes of calls = m [tex]\times[/tex] cost per minute
cost for m number of minutes of calls = [tex]0.22 \times m[/tex]
Let the Total Cost be represented as C.
So, we can write the cost function as:
[tex]C = 700+0.22m \ \{0\leq m\leq500\}[/tex]
Domain of a function is the valid input value to the function for which the output is defined.
Here, the domain is [0, 500] i.e. 0 and 500 are inclusive.
So, the answer is:
[tex]C = 700+0.22m[/tex]
Domain is [0,500] or [tex]0 \leq m\leq 500[/tex]

Jacque needs to buy some pizzas for a party at her office. She's ordering from a restaurant that charges a $7.50 fee and $14 She wants to buy as many pizzas as she can, and she also needs to keep the delivery fee plus the cost of the pizzas under $60. Each pizza is cut into 8. She wonders how many total slices she can afford.
Answer:
The answer is 24
Step-by-step explanation:
If the restaurant fee is $7.5 and the price is $14 per pizza, she has $52.5 to spend on the pizzas after we deduct the restaurant fee.
That means she can get 52.5 / 14 = 3.75 pizzas.
Since she can't get .75 pizza, we can assume that she will order 3, which in total makes 8 x 3 = 24 slices.If she can however order 3.75 pizzas, .75 x 8 makes 6 slices so it is a total of 30 slices for 3.75 pizzas.I hope this answer helps.
The total slices she can afford is 30 and this can be determined by using the unitary method and forming the linear equation.
Given :
Jacque needs to buy some pizzas for a party at her office.She's ordering from a restaurant that charges a $7.50 fee and $14 for delivery.She wants to buy as many pizzas as she can, and she also needs to keep the delivery fee plus the cost of the pizzas under $60.The following steps can be used to determine the total slices she can afford:
Step 1 - Total cost to order one pizza is given by:
= 7.5 + 14
= $21.5
Step 2 - Let the total number of pizzas she can order be 'x'. So, the delivery fee plus the cost of the pizzas under $60 is represented by the equation:
14x + 7.5 = 60
14x = 52.5
x = 3.75
Step 3 - Now, according to the given data if one pizza contains 8 slices then 3.75 pizza contains:
[tex]= 3.75\times 8[/tex]
= 30 slices
The total slices she can afford is 30.

Greetings from Brasil...
Follow the reasoning.
288 ÷ 2 = 144
and 144 its a perfect square (144 = 12²)
It is visible that if we multiply 288 by 1/2, we will obtain a perfect square, but we will do this via a simple equation
288 · X = 144
X = 144 ÷ 288

Marissa has a Master's degree and earns an annual salary of $80,400. She works 40 hours per week for 48 weeks per year. Her sister has a Bachelor's degree and earns an average salary of $58,000. She works 40 hours a week for 52 weeks. How much greater is Marissa's hourly wage than her sister's hourly wage? Round your answer to the nearest whole dollar.
Answer:
$14
Step-by-step explanation:
Marissa has a Master's degree and earns annual salary of $80,400.
She works 40 hours per week for 48 weeks per year.
Her sister has a Bachelor's degree and earns an average of $58,000 per year.
She works 40 hours per week for 52 weeks per years.
Marissa works for a total of 40 × 48 = 1920 hours a year.
Her hourly wage = [tex]\frac{80,400}{1920}[/tex] = $42 (rounded up to nearest dollar).
Her sister works for a total of 40 × 52 = 2080 hours
Her hourly wage = [tex]\frac{58,000}{2080}[/tex] = $28 (rounded up to nearest dollar)
So Marissa's hourly wage is $42 - $28 = $14 more than her sister's hourly wage.

The measure of the arc NMK will be 183°. Then the correct option is B.
What is a circle?The circle is at equidistant of points drawn from the center. The radius of a circle is the distance between the center and the circumference.
The measure of the angle ∠MLK is 35°.
The major and minor arc is 117x and 107x.
We know that the angle ∠MLK is the half of the difference of the major arc to minor arc.
∠MLK = (arc KN – arc KM) / 2
35° = (177x - 107x) / 2
70° = 70x
x = 1°
Then the measure of the arc KN will be
Arc NK = 177 x 1
Arc NK = 177°
We know that the sum of the arc KN and KMN will be 360°.
mNK + mNMK = 360°
177° + mNMK = 360°
mNMK = 360° – 177°
mNMK = 183°
The measure of the arc NMK will be 183°.
Then the correct option is B.

Answer:
height = h = 13.4 cm
volume = V = 602.8 cm³
Step-by-step explanation:
area of a square base = 15 cm x 9 cm = 135 cm²
slant height of pyramid = 16m
solving height: (see attached image)
first step is to take the diagonal base:
side of base 15 = 15 / 2 = 7.5cm
side of base 9 = 9 / 2 = 4.5m
diagonal base = sqrt ( 7.5² + 4.5²) = 8.75 cm
therefore
height² = slant height² - diagonal base²
h² = 16² - 8.75²
h = 13.4 cm
solving the volume:
V = 1/3 * area of square base * h
V = 1/3 * 135 * 13.4
V = 602.8 cm³
