Answer and step-by-step explanation:
First, we will have to know at what time they will cross the line at the same time. So we can do the equation:
50 * 80 = 400
That means in 400 seconds they will be level again. Now, let's find Ali's amount of laps for 400 seconds, if it takes Ali 50 seconds for one lap. We can do:
400/50 = 8
This means it will take Ali 8 seconds to be leveled with Omar. Now Omar has the equation:
400/80 = 5
Because it takes him 80 seconds to take one lap. Therefore, it will take Ali 8 laps, and Omar 5 laps to be at the same starting line. Hope this helps!
Does anyone know the answer to this?
Answer:
10.5.
Step-by-step explanation:
By similar triangles:
IJ / 21 = 8 /(8+8) = 1/2
IJ / 21 = 1/2
IJ = 1/2 * 21
= 10.5.
A soccer player is going to kick a soccer ball from one corner of a field to the opposite corner. If the field is 68 meters long and 51 meters wide, how far will the soccer player have to kick the ball?
Answer:
85 m.
Step-by-step explanation:
Use Pythagoras Theorem:
x^2 = 51^2 + 68^2
= 7225
x = √7225
= 85

Q.2 Find the equation of the straight line passing through the A(-2, -4) and B(1, -7). (3)
Q.3 Find the equation of the straight line passing through (3, 5) and parallel to the line y = 2x+ 3 (2)
Q.4 Find the equation of the straight line passing through (5, 7) and gradient 3
Answer:
See answers below
Step-by-step explanation:
Standard equation of a line is expressed as y = mx+b
m is the slope
b is the y intercept
Given the coordinate points (-2, -4) and B(1, -7)
Slope m = y2-y1/x2-x1
m = -7-(-4)/1-(-2)
m = -7+4/1+2
m = -3/3
m = -1
Get the intercept
Substitute m = -1 and (1, -7) into y = mx+b
-7 = -1(1) + b
-7 = -1 + b
b = -7+1
b = -6
Get thw equation
y = mx+b
y = -x + (-6)
y = -x - 6
Q.3 The equation in point slope form is expressed as y - y0 = m(x-x0)
Given the point (3, 5)
x0 = 3
y0 = 5
Given the equation y = 2x+3
mx = 2x
m = 2
slope = 2
Substitute the slope and the point in the expression
y - 5 = 2(x -3)
y - 5 = 2x - 6
y - 2x = -6 + 5
y - 2x = -1
This gives the required equation
Q.4 The equation in point slope form is expressed as y - y0 = m(x-x0)
Given the point (5, 7)
x0 = 5
y0 = 7
Slope = 3
Substitute the slope and the point in the expression
y - 7 = 3(x -5)
y - 7 = 3x - 15
y - 3x = -15 + 7
y - 3x = -8
This give the required equation

because i mutipled
60 hamburgers
240÷2=120
120 for both each
120÷2=60

Find the next two terms in the sequence.
40, 10, –20, –50, . . .
A.
60, 80
B.
–80, –110
C.
–70, –100
D.
–70, –90
Answer:
B.
–80, –110
Step-by-step explanation:
-80 and -110
It is an arithmetic sequence. The difference = -30. It is the difference between each number in the sequence: 10-40=-30
-50-30=-80
-80-30 =-110
-80
First Identify the sequence being made here.
10-40 = -30
-20-10 = -30
-50-(-20) = -30
Therefor this pattern is decreasing by a rate of 30 so to continue this, just subtract 30 from -50.
-50-30 = -80
The next term is -80.

Pat is fencing two areas for their pigs and ducks. The length of one area is 2m more than double its width. The length of the other area is 3m less than its width. If the width of both areas is 6m, how much fencing will they need?
Answer:
40 meters for area 1
12 meters for area 2 so combined it will be 52 meters
this one is hard
explanation is:
the length is 2m more than the width doubled and so the width is 6 so 6 times 2 is 12 + 2 (from the 2m longer) is 14 so then using the formula for rectangles (the shapes may be rectangles due to the lengths being different from the width) (length x 2) + (width x 2)= 40=28+12 and 6+12=18 now 18+ 40 combined gives us 52
Find the measure of angle A
can you show me how to solve this problem
Answer:
A = 20 degrees
Step-by-step explanation:
Both legs of the triangles are 2x and equal, so we know that the triangle is isoceles. That means both acute angles are equal as well.
In a triangle there are 180 degrees
180 - 140 = 40
40 remainding degrees/ 2 equal angles
A = 20 degrees
Answer:
angle a = 20
Step-by-step explanation:
So like the person above me said
180-140=40
40 divided by 2 is 20

Answer:
Distance between mall and library is 6.32 miles.
Step-by-step explanation:
Coordinates of the door to the library is at (2, 4) and door to the mall is at (8, 4).
Since, distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
Distance = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
By this formula,
Distance between (2, 4) and (8, 4) will be,
Distance = [tex]\sqrt{(8-2)^2+(2-4)^2}[/tex]
= [tex]\sqrt{36+4}[/tex]
= [tex]\sqrt{40}[/tex]
= 6.32 miles

Step-by-step explanation:
the areas of three rectangle is 3:7:8 . if the average area of the three rectangle is 18cm2,find the different between the biggest rectangle and the smallest rectangle .
Answer:
15 sq cm
Step-by-step explanation:
Let 3x = area of 1st rectangle
7x = area of 2nd rectangle
8x = area of 3rd rectangle
(3x + 7x + 8x)/3 = 18
3x + 7x + 8x = 54
18x = 54
x = 3
3x = 3(3) = 9 = area of 1st rectangle (smallest)
8x = 8(3) = 24 = area of 3rd rectangle (biggest)
24 - 9 = 15 sq cm

Water is leaking out of a tank at a steady rate the tank started with 75 gallons after 15 hours the tank has 33 gallons of water
Answer:
The equation will be "[tex]y=-2.8 x+75[/tex]".
Step-by-step explanation:
The given values are:
Started with,
= 75 gallons
After 15 hrs,
Tank has,
= 33 gallons
Now,
The slope will be:
= [tex]\frac{33-75}{15}[/tex]
= [tex]\frac{-42}{15}[/tex]
= [tex]-2.8[/tex]
Thus,
The equation is "[tex]y=-2.5x+75[/tex]".

Write an equation of the line that passes through (3,3) and (4,8)
Answer:
y=5x-12
Step-by-step explanation:
find the slope first which is (8-3)/(4-3)=5
Then that’s your slope.
after that plug the x into the equation I wrote so that means y=5(3)-12 and you should get the y value which is simple enough if you know how to do it.
