A car and a motorcycle leave the city at the same time and drive to a lake that is 120 km away. The speed of the motorcycle is 20 km per hour greater than the speed of the car, so the motorcycle arrives at the lake 1 hour before the car. Find the speed of the car and the speed of the motorcycle. Plz answer fast!!
Answer:
40 km/h and 60 km/hStep-by-step explanation:
Let the speed of the car is x, then the speed of motorcycle is x + 20
The distance = 120 km
Time:
120/x = 120/(x + 20) + 1120(x + 20) = 120x + x(x +20)120x + 2400 = 120x + x² + 20xx² + 20x = 2400 x² + 2*10x + 10² = 2500(x + 10)² = 50²x + 10 = 50x = 40Speed of the car is 40 km/h
Speed of the motorcycle is 60 km/h
Answer:
Speed of the car is 40 km/h
Speed of the motorcycle is 60 km/h

Answer:
Hi how are you doing today Jasmine
you invest 10000 that will earn 8.3% every year how much will you earn in 12 years.
Answer:
$16034.03
Step-by-step explanation:
I'm going to assume it's compound interest
10000(1+.083)^12
26034.03
subtract the original amount to find out how much was earned
26034.03-10000=16034.03
Answer:
$9960 would be earning in 12 years
Step-by-step explanation:
8.3% of 10,000 is 830
1% of 10,000 is 100
.3 would just be 30
.4 would be 40
etc etc
so 830 times 12(years) is $9960.00
The area of a rectangular field is 48m2 and one of its sides is 6m . How long will a lady take to cross the field diagonally at the rate of 20m/min
Answer:
It will take her approximately 28 seconds to cross the diagonal of the pitch
Step-by-step explanation:
If we can find the length of the diameter of the field (in Metres), we can easily find the time it takes her to cross this length using motion equations.
Step one: Find the length of the field from its area.
The field is rectangular in shape. The area of the field is 48m^2. To get the area of the field, we had to multiply its length and its breadth.
i.e area = length X breadth.
Let us assume that the breadth = 6m
its length will be area / breadth = 42/ 6 = 7m
The length of the pitch = 7 m
Step Two: Find the length of the diagonal using Pythagoras' theorem.
From Pythagoras'theorem, the length of the diagonal can be obtained by
[tex]diagonal = \sqrt{l^2 +b^2}[/tex]
[tex]diagonal = \sqrt{6^2+ 7^2} = 9.22m[/tex]
The length of the diagonal is 9.22m
Step three: Find the time using her speed and the distance she needs to cover.
Time = distance / speed
time = 9.22 /20 = 0.46 minutes
It will take her approximately 28 seconds to cross the diagonal of the pitch

The height odf a regtangular pyramid is 4 inches. The base of the pyramid measures 9 inches by 9 inches. What is the volume of the rectagular pyramid in cubic inches?
Answer:
[tex]V=108\ \text{inches}^3[/tex]
Step-by-step explanation:
Given that,
The height of a rectangular pyramid is 4 inches
The base of the pyramid measures 9 inches by 9 inches.
We need to find the volume of the rectangular pyramid. The formula for the volume of the rectangular pyramid is given by :
[tex]V=\dfrac{lbh}{3}[/tex]
Substitute all the values,
[tex]V=\dfrac{4\times 9\times 9}{3}\\\\V=108\ \text{inches}^3[/tex]
So, the volume of the rectangular pyramid is [tex]108\ \text{inches}^3[/tex].
What is the slope of y = -5 + 42?
Answer:
slope should be -5
Step-by-step explanation:
the equation is y=-5+42
slope equation form is y=mx+b
m is the slope in the equation, b is the y-intercept(where it hits the line if graphed)
so b should be 42 and slope should be -5

There were 35 students in a class. If 5/7 of the students were present on Monday, then how many students were NOT present on Monday.
Which is NOT an equivalent fraction to:3/4.
Answer:
2/7 is correct answer
oky na
[tex] \Large \underline{\tt Given} :[/tex]
[tex] \\ [/tex]
Total number of students = 35Students present on Monday = [tex] \tt \dfrac{5}{7}\: of \:35[/tex][tex] \\ [/tex]
[tex] \Large \underline{\tt To \: Find} :[/tex]
[tex] \\ [/tex]
Students not present on Monday = ?[tex] \\ [/tex]
[tex] \Large \underline{\tt Solution} :[/tex]
[tex] \\ [/tex]
As, we have :
Students present on Monday = [tex] \tt \dfrac{5}{7} of 35[/tex]
[tex] \\ [/tex]
[tex] \tt : \implies Students \: present \: on \: Monday = \dfrac{5}{7} \times 35[/tex]
[tex] \tt : \implies Students \: present \: on \: Monday = \dfrac{5}{\cancel{7}} \times \cancel{35}[/tex]
[tex] \tt : \implies Students \: present \: on \: Monday = 5 \times 5[/tex]
[tex] \tt : \implies Students \: present \: on \: Monday = 25[/tex]
[tex] \\ [/tex]
Now, we have to find students not present on Monday :
As, we have :
Total number of students = 35 Students present on Monday = 25[tex] \\ [/tex]
Therefore,
Students absent on Monday = 35 - 25 = 10

Hence, 10 students were not present on Monday.

HELP ASAP PLEASE! I need to write an equation of the line in slope-intercept form.
Answer:
y=2x-2
Step-by-step explanation:
The slope-intercept form is known as y=mx+c
y= the y coordinate
m= the gradient/slope
x= the x coordinate
c= y intercept
The y intercept is when the line crosses the y axis. The graph shows the y intercept is (0,-2). This means our value of c is -2.
Now we must find the value of m. The value of m is the slope of the graph. I usually figure out the slope by doing the change in y / change in x (by counting along how many squares). The change in y is two squares up and the change in x is one square along.
Therefore, the gradient would be 2/1. This equals 2 (so m=2).
Now, we can easily substitute these values into the equation given earlier. Therefore, the equation would be y=2x-2.
