Ralph and Liza are both driving from Los Angeles to Santa Fe. Ralph leaves at 7:00 and averages 60 mph (miles per hour) on the way. Liza leaves at 7:25 and averages 65 mph on the way. The situation is modeled by this system,
where x is the number of hours after Liza leaves and y is the distance each
will travel:
y = 60x + 25
y = 65x
How long after Liza leaves will she pass Ralph, and how far will they each
have traveled?
A. Liza will pass Ralph after 4 hours, and they each will have traveled
260 miles.
B. Liza will pass Ralph after 3 hours, and they each will have traveled
205 miles.
C. Liza will not pass Ralph, because she will never catch up with him.
D. Liza will pass Ralph after 5 hours, and they each will have traveled
325 miles.
Answer:
I'm pretty sure its D
Step-by-step explanation:
Liza will pass Ralph after 5 hours, and they each will have traveled 325 miles. Then the correct option is D.
What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
Ralph and Liza are both driving from Los Angeles to Santa Fe.
Ralph leaves at 7:00 and averages 60 mph (miles per hour) on the way.
Liza leaves at 7:25 and averages 65 mph on the way.
The situation is modeled by this system will travel:
y = 60x + 25
y = 65x
where x is the number of hours after Liza leaves and y is the distance each
The time after Liza leaves will she pass Ralph will be
65x = 60x + 25
5x = 25
x = 5 hours
Then the distance covered by both after 5 hours will be
y = 65 (5)
y = 325 miles

If angle MNO is a rectangle, and MO = 54 , what is the length of overline NP ? A. 34 B. 22 C. 18 D. 108 E. 27 F. Cannot be determined
Answer:
Option (E)
Step-by-step explanation:
LMNO is a rectangle.
MO = 54
By the property of a rectangle,
1). Diagonals are equal in length.
2). Diagonals equally bisect each other.
Since, MO = LN
Therefore, LN = 54
Since, NP = [tex]\frac{1}{2}(LN)[/tex]
NP = [tex]\frac{54}{2}[/tex] = 27
Option (E) will be the correct option.
Answer:
E ;27

Step-by-step explanation:
Larry mows lawns for $50 an hour. Last week, he gave all his customers a 20% discount off his hourly rate. Mrs. Grinnell hired Larry last week to mow her lawn, and Larry applied a 10% new customer discount to his already discounted rate. If Larry worked on Mrs. Grinnell's lawn for 3 hours, how much does Mrs. Grinnell owe Larry?
Answer:
If Larry worked on Mrs. Grinnell's lawn for 3 hours, Mrs. Grinnell would owe Larry $108.
Step-by-step explanation:
You have to find the total amount Larry would receive with $50 an hour:
$50*3=$150
Now, you have to calculate the amount with a 20% discount by calculating the 20% of $150 and subtracting that amount from $150:
$150*20%=$30
$150-$30=$120
Then, you have to calculate the 10% of $120 and subtract that amount from $120:
$120*10%=$12
$120-$12=$108
According to this, the answer is that if Larry worked on Mrs. Grinnell's lawn for 3 hours, Mrs. Grinnell would owe Larry $108.

Hi guys i need help with this problem y=mx+b
determine the number of solutions, y=x+2 and x=-1
There is only one solution.
y = x+2
x = -1
Substitute x = -1 in y = x+2
y=-1+2
y = 1
We only get the single value of y and x so It's clear that there's only one solution.

Mae Ling earns a weekly salary of $375 plus a 7.0% commission on sales at a gift shop. How much would she make in a work week if she sold $4,600 worth of merchandise?
Answer:
$697
Step-by-step explanation:
Given that :
Weekly earning = $375 plus 7% commission on sales
Earning if she sold $4600 worth of merchandise
Commision on sales = 7% of 4600
Commission = 0.07 * 4600
Commission on sales = $322
Total earning = $375 + $322
Total earning = $697

The tens digit of a two digit number is five more than the units digit. Seven times the sum of the digits of this number is 3 less than the number itself. Find the number.
Answer:
94
Step-by-step explanation:
Let the unit's digit = [tex]y[/tex]
Let the ten's digit = [tex]x[/tex]
Then the number will be equal to [tex]10x+y[/tex]
Now, using the given statement:
[tex]x=y+5 ..... (1)[/tex]
[tex]7(x+y) = 10x+y-3\\\Rightarrow 7x+7y=10x+y-3\\\Rightarrow 6y-3x=-3 ..... (2)[/tex]
Now, using the equation (1) in equation (2):
[tex]6y-3(y+5) =-3\\\Rightarrow 3y-12=0\\\Rightarrow y =4[/tex]
By equation (1):
[tex]x = 4+5 \\\Rightarrow x =9[/tex]
Therefore, the number is :
[tex]10x+y= 10\times 9 +4 = \bold{94}[/tex]

does 9, 16, 5 make a right triangle? Explain
Answer:
By virtue of the Pythagorean Theorem, in a right triangle the sum of the squares of the smaller two sides equals the square of the largest side.
It does not make a right triangle. 9^2 + 5^2 = 106 while 16^2 = 256. So it is not same.
