If Noah ran 2 1/2 miles in 3/5 How fast, in miles per hour, did he run?
Answers
speed=distance/time
a] Noah's speed:
distance=2.5 miles
time=3/5 hours
speed=(2 1/2)/(3/5)
=(5/2)/(3/5)
=5/2×5/3
=25/6
=4 1/6 mi/hr
Emily's speed
distance=3 3/4 miles
time=5/6 hour
thus
speed=(3 3/4)/(5/6)
=15/4)/(5/6)
=15/4×6/5
=4 1/2 mi/hr
Anna's speed:
distance=3 1/3 miles
time=3/5
speed=(3 1/3)/(3/5
=(10/3)/(3/5)

Answer:

Step-by-step explanation:
I am assuming the question is asking which x value plugged into the function will give you a zero so
(-1)3 -8(-1)2 -23(-1)+30
so that simplyfiys to -1-8(1)+23+30
so that is -1-8+53
so -9+53
= 44
trying 3 we get
(3)3-8(3)2-23(3)+30
so that is 27 -72-69+30
and that is not zero
trying -10
we get
(-10)3-8(-10)2-23(-10)+30
which is -1000- 800+230+30
that is not zero so lastly trying 1 we get
(1)3-8(1)2-23(1)+30
which is 1-8-23+30
which is -7+7 which is zero

Brian is going to take a flight from Boston, Massachusetts, to San Francisco,
California. The flight leaves Boston at 10:25 p.m. Boston time and arrives in
San Francisco at 6:10 a.m. San Francisco time. If San Francisco is in the
Pacific time zone and Boston is in the eastern time zone, how long is the
flight? Use the following to help you answer the question 12:00p.m. eastern
time = 11:00 a.m. central time = 10:00 a.m. mountain time = 9:00 a.m. Pacific
time.
A. 7 h 45 min
B. 3 h 45 min
C. 10 h 45 min
D. 5 h 45 min
Answers
Answer:
C
Step-by-step explanation:
The flight duration is 9:10 a.m. - 10:25 p.m. = 10 hours and 45 minutes. The correct option is C.
How to calculate the time?To determine the duration of the flight, we need to calculate the time difference between the departure time from Boston and the arrival time in San Francisco, taking into account the time zone difference.
We know that San Francisco is in the Pacific time zone, which is 3 hours behind the Eastern time zone (where Boston is located). So, when it is 10:25 p.m. in Boston, it is actually 7:25 p.m. in San Francisco.
The arrival time in San Francisco is given as 6:10 a.m. San Francisco time, which is 9:10 a.m. Eastern time (since Pacific time is 3 hours behind Eastern time).
Therefore, the flight duration is:
9:10 a.m. - 10:25 p.m. = 10 hours and 45 minutes
So, the answer is C. 10 h 45 min.

Convert the following Logarithmic Equation into a Exponential Equation.
log_3(-2x+1)=-2y+6
Answers
Answer:
The conversion is given by [tex]3^{-2y+6} = -2x+1[/tex].
Step-by-step explanation:
Logarithmic Equation to Exponential Equation:
To realize the conversion of a logarithmic equation to an exponential equation, we need to understand the meaning of a logarithim. We have that:
[tex]\log_{a} b = c[/tex]
Means that:
[tex]b = a^c[/tex]
We are given the following equation:
[tex]\log_{3} (-2x+1) = -2y + 6[/tex]
It means that
[tex]3^{-2y+6} = -2x+1[/tex]
Which is the conversion.
Barbie spent $166 on clothes. She bought some shirts that cost $14 each and some pants that cost $22 each. She bought a total of 9 items. Select the system of equations to determine how many shirts and pants Barbie purchased. Let x represent the number of shirts and y represent the number of pants.
x + y = 166
14x + 22y = 9
x + y = 166, , 14x + 22y = 9,
x + y = 9
22x + 14y = 166
x + y = 9, , 22x + 14y = 166,
x + y = 9
14x + 22y = 166
x + y = 9, , 14x + 22y = 166,
x + y = 36
166x + 9y=14x + 22y
Answers
The correct system of equations will be;
⇒ x + y = 9
And, $14x + $22y = $166
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Barbie spent $166 on clothes.
The cost of each pant = $22
The cost of each shirt = $14
Total number of items = 9
Now,
Let number of shirts = x
And, The number of pants = y
Since, Total number of items = 9
So, we can formulate;
⇒ x + y = 9
And, The cost of each pant = $22
The cost of each shirt = $14
So, We can formulate;
⇒ $14x + $22y = $166
Therefore, The correct system of equations will be;
⇒ x + y = 9
And, $14x + $22y = $166

x-2=-3x+2 pls show how to fully solve it
Answers
Answer:
x = 1
Step-by-step explanation:
One thing that is necessary to learn this is that whatever you do to one side, you must do to the other. If you substract 2, you must substract 2 from both sides.
Here are all the steps:
x - 2 = -3x + 2
x = -3x + 4 (by adding 2 to both sides)
4x = 4 (by adding 3x to both sides)
x = 1 (by dividing both sides by 4)

Step-by-step explanation:
Add [tex]2[/tex] to both sides of the equation:
[tex]x-2=-3x+2[/tex]
[tex]x-2+2=-3x+2+2[/tex]
Simplify:
Add the numbers:[tex]x[/tex][tex]-2+2=-3x+2+2[/tex]
[tex]x=-3x+2+2[/tex]
Add the numbers:[tex]x=-3x+2+2[/tex]
[tex]x=-3x+4[/tex]
[tex]x=-3x+4[/tex]
Add [tex]3x[/tex] to both sides of the equation:
[tex]x=-3x+4[/tex]
[tex]x+3x=-3x+4+3x[/tex]
Simplify:
Combine like terms:[tex]x+3x=-3x+4+3x[/tex]
[tex]4x=-3x+4+3x[/tex]
Combine like terms:[tex]4x=-3x+4+3x[/tex]
[tex]4x=4[/tex]
[tex]4x=4[/tex]
Divide both sides of the equation by the same term:
[tex]4x=4[/tex]
[tex]\frac{4x}{4} =\frac{4}{4}[/tex]
Simplify:
Cancel terms that are in both the numerator and denominator:[tex]\frac{4x}{4} =\frac{4}{4}[/tex]
[tex]x=\frac{4}{4}[/tex]
Divide the numbers:[tex]x=\frac{4}{4}[/tex]

Step-by-step explanation:
What the information at the top tells us is that triange ABC is an isosceles triangle. In an isosceles triangle the two base angles are congruent, this means that <A=<C. Additionally, because of vertical angles we know that <C is equal to 38. So to find m<B use the expression 180-(2*38). This simplifies to 180-76, which is 104.
