Answer:
1.5 sec by meters
Step-by-step explanation:
90 meters/60 sec=1.5
Darrel walks at a unit rate of 1.5 m/sec.
What is speed?Speed is defined as the rate of change of position in unit time.
Mathematically,
Speed = Distance/Time
Now it is given that,
Distance in walk by Darrell = 90 meters
Time taken by Darell to walk 90 meters = 60 seconds
Therefore Speed i.e unit rate of walk is given as,
Unit rate of walk = Distance in walk by Darrell / Time taken by Darell to walk 90 meters
⇒ Unit rate of walk = 90/60 m/sec
⇒ Unit rate of walk = 3/2 m/sec
⇒ Unit rate of walk = 1.5 m/sec
Thus, Darrel walk at a unit rate of 1.5 m/sec.

Sandra drove 117 miles in an hour and 30 minutes to visit her son at college, without stopping. If the speed limit is 60 mph, explain why she should or should not get a speeding ticket. Make sure to include mathematical computations in your answer.
Answer:
She should get a speeding ticket. The speed limit is 60mph and her speed was 78 mph, 18 miles over the speed limit.
Step-by-step explanation:
She drove 117 miles in 90 minutes.
117/90 = 1.3 miles per minute
1.3 miles x 60 minutes = 78 mph

I kinda need help and an explanation Cant understand
Answer:
look in explanation
Step-by-step explanation:
Seeing as most of your answers are wrong, I'll start from the beginning.
a rational number is a number that can be expressed as a fraction.
an integer is a whole number.
an irrational number is a number that cannot be expressed as a fraction.
an integer is also always a rational number.
Using this, we can sort the values.
-77/11 can be simplified as -7, which is an integer.
the square root of 144 is 12, which is an integer.
0.25 is a decimal that can be expressed as a fraction, which makes it a rational number that is not an integer.
the square root of 20 is a value that cannot be expressed as a fraction, which makes it irrational.
17/4 is a fraction that is not a whole number, which makes it a rational number but not an integer.
finally, 2*the square root of 10 is irrational.

Step-by-step explanation:
We can split up the exponent into multiple products: [tex](-2x^3)^3=(-2)^3*(x^3)^3[/tex].
We know that [tex](-2)^3=(-2)*(-2)*(-2)=-1*-1*-1*2*2*2=-1*8=-8[/tex].
We also know that [tex](x^3)^3=x^{3*3}=x^9[/tex].

What is the distance between the points (1,6) and (-7,3) on a standard coordinate plane?
39
73
173
55
Step-by-step explanation:
I think you are missing the square root signs or so in the answer options.
the distance between 2 points is calculated by using Pythagoras for right-angled triangles.
c² = a² + b²
c is the Hypotenuse of the triangle and the distance between the points, which are the end points of the Hypotenuse.
a and b are the legs and enclose the 90 degree angle. they are the differences of the x and y coordinates between the 2 points.
so,
distance² = (1 - -7)² + (6 - 3)² = 8² + 3² = 64+9 = 73
=>
distance = sqrt(73)

angle1,2 , and angle3 form a straight line. If m angle3 is six more than twice m angle1 m angle2 is 27 less than m angle3 find m angle2
Since it's an angle on a straight line, the value of angle 2 is 23.25°
Angle 1 = m
Angle 2 = m - 27
Angle 3 = 2m + 6
It should be noted that the sum of angles in a straight line is equal to 180°, therefore we need to equate all the angles given to 180°. This will be:
m + (m - 27) + (2m + 6) = 180°
m + m - 27 + 2m + 6 = 180°
4m = 180° + 27° - 6°
4m = 201°
m = 201/4
m = 50.25°
Therefore, angle 2 will be:
m - 27 = 50.25 - 27 = 23.25°

Step-by-step explanation:
D = b² - 4ac
#1D = 10² - 4 · 3 · 2
D = 100 - 24
D = 76
#2D = (-5)² - 4 · 1 · (-4)
D = 25 - (-16)
D = 26 + 16
D = 42
#3D = 7² - 4 · 1 · (-8)
D = 49 - (-32)
D = 49 + 32
D = 81
#4D = 0² - 4 · 1 · (-9)
D = 0 - (-36)
D = 36
#5D = (-6)² - 4 · 5 · 10
D = 36 - 200
D = - 164

A horse travels at about 65 kph. At this rate, how far can it travel in 20 minutes
Answer: Approximately 21.667 km
This value as a fraction is 65/3, but I think the decimal form is probably more practical in real world settings.
======================================================
Work Shown:
20 min = 1/3 of an hour, since 20/60 = 1/3. In other words, there are three chunks of 20 minutes that make up a full hour.
distance = rate*time
distance = (65 kph)*(1/3 hr)
distance = (65*1/3) km
distance = (65/3) km
distance = 21.667 km which is approximate
Answer:
Distance rate=Rate x Time
Distance= (75 km/h) 20 mins
Convert 20 mins in hours= 1/3 h
Distance= (75 km/h) (1/3 h)= 25 km.....
