Answer:
6 minutes
Step-by-step explanation:
The rates add when expressed in terms of jobs per minute.
1/10 + 1/15 = 3/30 + 2/30 = 5/30 = 1/6
The two together can complete 1/6 jobs per minute, so it will take them 6 minutes to complete 1 job.
In Circle YmAD = 68° and mBC = 156. Find mZ1
Answer:
m<1 = 112°
Step-by-step explanation:
Given:
Arc BC = 156°
Arc AD = 68°
Required:
m<1
Solution:
m<1 = ½(arc BC + arc AD) => based on intersecting chords angle measure theorem
Substitute
m<1 = ½(156° + 68°)
m<1 = ½(224)
m<1 = 112°
If you are driving 60km/h and you speed up to 70km/h over a period of 5 seconds, what is
your acceleration?
Answer:
fast as heck 0.o (i think 170
Step-by-step explanation:
Answer:
Step-by-step explanation:
solution:
Data,
driving speed of car intially velocity at = Vi = 60km/h
the speed was then raised to final velocity at = Vf = 70km/h
the total period of speed raised = t = 5 sec
Req, acceleration = ?
put the formulae : a = Vf - Vi/t
a = 70 - 60/5
a = 2 m/sec2 ans
/ means divided by,

Answer: Choice B
They traveled 250 miles in 4 hours. Their speed was 62.5 mph.
=============================================================
Explanation:
Start at point X. Draw a horizontal line straight across until you reach the y axis. You should arrive at y = 250. This tells us that they traveled 250 miles.
Go back to point X. Draw a vertical line until you reach the x axis. You should reach x = 4. This indicates 4 hours.
Pairing up the two values together means they traveled 250 miles in 4 hours. Divide the distance over time to get the speed
speed = distance/time = 250/4 = 62.5 miles per hour
--------
Side note: unfortunately your teacher chose the label uppercase X for the point, which may be a bit confusing since it could clash with the lowercase x along the horizontal axis.
Another note: the speed represents the slope of the line
Does the quadratic function
y = 3x2 + 7x - 8
have one, two or no real zeros?
Utilize the quadratic formula to
determine the answer.
[?] real zeros
Answer:
Two real roots
Step-by-step explanation:
The portion of the quadratic formula that determines the number of roots is
b² - 4ac
If it's positve there are two real roots
If it's zero there is one real root
If it's negative there are no real roots
------------------------------
b² - 4ac = 7² - 4(3)(-8)
b² - 4ac = 49 + 96
b² - 4ac = 145
Two real roots since 145 is positive
The quadratic equation has two real zeroes
What is quadratic equations?
The polynomial equations of degree two in one variable of type f(x) = ax2 + bx + c = 0 and with a, b, c, and R R and a 0 are known as quadratic equations. It is a quadratic equation in its general form, where "a" stands for the leading coefficient and "c" for the absolute term of f. (x). The roots of the quadratic equation are the values of x that fulfill the equation (, ).
It is a given that the quadratic equation has two roots. Roots might have either a real or imaginary nature.
What is quadratic formlua?
D=b²-4ac
x=(-b±√(b²-4ac))/2a
y = 3x² + 7x - 8
On comparing with ax²+bx+c, we get
a=3, b=7 and c=-8
Using Quadratic formula
D=b²-4ac
=7²+4x3x8
=49+96
=145>0
Hence it has real zeroes

Find the area of the trapezoid
Answer:
7.5 units^2
Step-by-step explanation:
So, let's just break apart this trapezoid into easier shapes to work with.
We can make a 1x3 rectangle with the squares that are fully covered in.
Then, make a triangle with the squares that are partially covered in above and another triangle for those below.
Now, calculating time.
With the rectangle, do Length * Width, so 1 * 3 = 3.
With the upper triangle, do (Base * Height) / 2, so (3 * 2) / 2 = 3
With the lower triangle, do (Base * Height) / 2 as well, so (3 * 1) / 2 = 1.5
Add these all up and you get 7.5 units^2

2,000.h for h = 0.004
2,000 h =
Answer:
[tex]h=2\times 10^6[/tex]
Step-by-step explanation:
We need to find h for the following condition.
2,000×h = 0.004
Dividing both sides by 2000
[tex]\dfrac{2000h}{2000}=\dfrac{0.004}{2000}\\\\h=0.000002\\\\h=2\times 10^6[/tex]
So, the value of h is equal to [tex]2\times 10^6[/tex].

A random sample of 300 balls hit into play in college baseball games is taken. For each ball hit into play, it is recorded whether the ball was hit to the left, center, or right of the field, and whether the ball resulted in a hit or an out. Which of the following is the appropriate null hypothesis to test if there is a relationship between the direction of the ball and if it resulted in a hit or an out?
(A) H_0H0: The proportion of balls hit to the left, right, and center is the same.
(B) H_0H0: The proportion of balls that result in hits and outs is the same.
(C) H_0H0: The distribution of the direction of the ball is the same for the population of hits and the population of outs.
(D) H_0H0: The direction of the ball and whether it results in a hit or an out are independent.
(E) H_0H0: There is an association between the direction of the ball and whether it results in a hit or an out.
Answer:
(D) H_0H0: The direction of the ball and whether it results in a hit or an out are independent.
Step-by-step explanation:
Given that
There is 300 balls random sample is taken
We need to find out the appropriate null hypothesis that lies between the ball direction and lead to a hit or an out
So
Based on the given options, the option d is correct as the ball direction and its results either be hit or on out would represent that they are independent
Therefore the option d is correct
