A person on a moving sidewalk travels 24feet the in 7 seconds. The moving side walk has a length of 180 feet. How long will it take to move from one end to the other?
Given:
A person on a moving sidewalk travels 24 feet the in 7 seconds.
The moving side walk has a length of 180 feet.
To find:
Time taken by the person to move from one end to the other.
Solution:
A person on a moving sidewalk travels 24feet the in 7 seconds.
The speed of the person is
[tex]\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}[/tex]
[tex]\text{Speed}=\dfrac{24}{7}[/tex]
[tex]\text{Speed}=\dfrac{24}{7}[/tex]
The moving side walk has a length of 180 feet.
[tex]\text{Time}=\dfrac{\text{Distance}}{\text{Speed}}[/tex]
[tex]\text{Time}=\dfrac{180}{\dfrac{24}{7}}[/tex]
[tex]\text{Time}=\dfrac{180}{1}\times \dfrac{7}{24}[/tex]
[tex]\text{Time}=52.5[/tex]
Therefore, the time taken by the person to move from one end to the other is 52.5 seconds.
find the value of x.
Answer:
x ≈ 55.9°
Step-by-step explanation:
Using the sine ratio in the right triangle
sinx = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{24}{29}[/tex] , then
x = [tex]sin^{-1}[/tex] ([tex]\frac{24}{29}[/tex] ) ≈ 55.9° ( to 1 dec. place )

JKL = 108 degrees
KLJ = 27 degrees
LJK = 45 degrees
Step-by-step explanation:
Add all the values of the triangle angles together to get 20. Then divide 180 by 20 to get 9 (The sum of all the angles in the triangle always equals 180 degrees).
JKL = 12x = 12(9) = 108
KLJ = 3x = 3(9) = 27
LJK = 5x = 5(9) = 45
A group of 2 adults and 4 children spent $38 on tickets to a museum. A group of 3 adults and 3 children spent $40.50 on tickets to the museum. Based on this information, how much is an adult ticket, and how much is a child ticket?
2a + 4c = 38.00
3a + 3c = 40.50
What values of a and c represent the solution to the system?
a =
c =
Answer:
a=8
c=5.5
Step-by-step explanation:
solve simultaneously:
2a + 4c = 38.00
3a + 3c = 40.50
times the first eq. by 3 and the second by 2
6a + 12c = 114
6a +6c = 81
subtract from one another
6a + 12c = 114
-6a +6c = 81
6c = 33
c=5.5
3a + 3x5.5 = 40.50
3a= 24
a=8

A dishwasher uses 11 liters of water for each cycle. A washing machine uses 5 times as much water as a
dishwasher uses for each load. Combined, how many milliliters of water are used for 1 cycle of
each machine?
Answer:
55,000 milliliters
Step-by-step explanation:
So if washing machine uses 5 times more than dishwasher
Dishwasher: 11 litters of each cycle
Washing machine: 11 x 5= 55 litters for each machine in litters
If 1 litter is equal to 1000 milliliter then 55 x 1000 = 55,000 milliliters
FORMULA for milliliter: multiply the volume value by 1000

Use the equation to predict the number of students in a school with 120 staff members.
Answer:
Step-by-step explanation:
easy y is 120
Answer:
1020 students
Step-by-step explanation:
We have the equation y = 0.1x + 18
If we have a school of 120 staff members, we can just set y = 120 and solve for the predicted total number of students, x.
120 = 0.1x +18
0.1x = 102
x = 1020 students
What is the ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths?
Given:
One midsegment of an equilateral triangle.
To find:
The ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths.
Solution:
All sides of an equilateral triangle are same.
Let a be the each side of the equilateral triangle.
Length of the midsegment is equal to the half of the non included side or third side.
[tex]Midsegment=\dfrac{a}{2}[/tex]
The sum of two side is
[tex]a+a=2a[/tex]
Now, the ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths is
[tex]\text{Required ratio}=\dfrac{\text{Length of midsegment}}{\text{sum of two sides}}[/tex]
[tex]\text{Required ratio}=\dfrac{\dfrac{a}{2}}{2a}[/tex]
[tex]\text{Required ratio}=\dfrac{a}{4a}[/tex]
[tex]\text{Required ratio}=\dfrac{1}{4}[/tex]
[tex]\text{Required ratio}=1:4[/tex]
Therefore, the ratio of the length of one midsegment of an equilateral triangle to the sum of two of its side lengths is 1:4.

Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 20)(0,20) and (2, 720)(2,720).
Answer:
The exponential function that goes through [tex](x_{1},y_{1}) = (0,20)[/tex] and [tex](x_{2}, y_{2}) = (2,720)[/tex] is [tex]y = 20\cdot 6^{x}[/tex].
Step-by-step explanation:
Let be an exponential function of the form [tex]y = a\cdot b^{x}[/tex] that goes through [tex](x_{1},y_{1}) = (0,20)[/tex] and [tex](x_{2}, y_{2}) = (2,720)[/tex]. Then, we have the following system of equations:
[tex]20 = a\cdot b^{0}[/tex] (1)
[tex]720 = a\cdot b^{2}[/tex] (2)
By dividing (2) by (1), we obtain the value for [tex]b[/tex]:
[tex]\frac{720}{20} = b^{2}[/tex]
[tex]b = \sqrt{\frac{720}{20} }[/tex]
[tex]b = 6[/tex]
And the value for [tex]a[/tex] is found by (1):
[tex]a = 20[/tex]
The exponential function that goes through [tex](x_{1},y_{1}) = (0,20)[/tex] and [tex](x_{2}, y_{2}) = (2,720)[/tex] is [tex]y = 20\cdot 6^{x}[/tex].

Joe is buying gift cards that are on sale for 15% off. He uses c – 0.15c to determine the sale price of gift cards. What is an equivalent expression that Joe could also use to determine the sale price of a gift card?
Answer:
0.85c
Step-by-step explanation:
Given :
Discount on sale = 15%
Price of gift card at discounted price = c - 0.15c
Equivalent expression could be :
(100% - 15%) * price
Price = c
(1 - 0.15)c
0.85c

The required expression that models represent the total cost, in dollars, to hire the dog walker for w walks is t = 27w + 30.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Here,
A dog walker charges a $ 30 sign-up fee to cover insurance costs and $ 27 per walk.
Let the total cost be t for the w walks.
So, the expression is given as,
t = 27w + 30
Where 27w represents the cost of w walks.
Thus, the required expression that models represent the total cost, in dollars, to hire the dog walker for w walks is t = 27w + 30.

Plot the following co-ordinates and find the fourth point D to make a square A (-1,3) B (1,-1) C(5,1).
Once you have found the missing coordinate use pythagoras to calculate the length of the sides.
Answer:
Step-by-step explanation:
Example: Solve this triangle
right angled triangle 5 12 c
Start with: a2 + b2 = c2
Put in what we know: 52 + 122 = c2
Calculate squares: 25 + 144 = c2
25+144=169: 169 = c2
Swap sides: c2 = 169
Square root of both sides: c = √169
Calculate: c = 13
The scatter plot shows a hiker's elevation above sea level over time. The equation of the trend line shown is y = 8.77x + 686. To the nearest whole number, predict what the hiker's elevation after 145 minutes
Answer:
707 feet above sea level
Step-by-step explanation:
2 hours and 25 minutes is about 2.4167 hours.
Therefore:
y=8.77x+686
y=8.77(2.4167)+686
y=21.1944+686
y=707.1944
So the hiker's elevation will be approximately 707 feet above sea level
