Janet can do a job in 3 hours, and Garry can do the same job in 2 hours. If Janet works for 1 hour before Garry comes to help, how long will it take them to do it together.
Answers
Answer:
48 minutes
Step-by-step explanation:
Given that:
Time taken by Janet = 3 hours
Janet's rate = 1/3 job / hour
Time taken by Garry = 2 hours
Garry's rate = 1/2
Rate of working together :
1/3 + 1/2 = (2 + 3) /6 = 5/6 job/hour
If Janet works for one hour before Garry joins ;
1/3 of the job has been done by Janet
1 - 1/3 = 2/3 of the job left
Hence to finish the job together, it will take :
Fraction of JOB left ÷ rate of working together
(2/3 ÷ 5/6)
= 2 /3 * 6/5
= 12 / 15
= 4 / 5 hours

Select all the pairs that could be reasonable approximations for the diameter and circumference of a circle. * 1 point A. 5 meters and 22 meters. B. 19 inches and 60 inches. C. 33 centimeters and 80 centimeters.
Answers
Answer:
B. 19 inches and 60 inches.
Step-by-step explanation:
Required
Select matching pairs
Represent diameter with D and Circumference with C
C is calculated as:
[tex]C = \pi D[/tex]
Where
[tex]\pi = 3.142[/tex]
A. D = 5m; C = 22m
Using: [tex]C = \pi D[/tex]
[tex]C = 3.142 * 5[/tex]
[tex]C = 15.71[/tex]
15.71 does not approximates to 22m.
Hence, the pair do not match
B. D = 19 in; C = 60 in
Using: [tex]C = \pi D[/tex]
[tex]C = 3.142 * 19[/tex]
[tex]C = 59.698[/tex]
59.698 approximates to 60.
Hence, the pair match
C. D = 33 cm; D = 80 cm.
Using: [tex]C = \pi D[/tex]
[tex]C =3.142 * 33[/tex]
[tex]C =103.686[/tex]
103.686 does not approximates to 22m.
Hence, the pair do not match
From the analysis above, only option B matches the diameter with the circumference

the sum of two numbers is 100 and their difference is 80, what are the two numbers
Answers
Answer:
The numbers are 90 and 10.
Step-by-step explanation:
Let the two numbers are x and y.
It has been given that sum of two numbers is 100. Hence, we have the equation,
x + y = 100 .........(i)
Now, the difference of these two numbers is 80. Thus, second equation is
x - y = 180......(ii)
Add equation (i) and (ii)
x + y + x - y = 100 + 80
2x = 180
Divide both sides by 2
x = 90
Substitute this value in (i)
90 + y = 100
y = 100- 90
y = 10
Therefore, the numbers are 90 and 10.

The sum of two numbers is 450 and the smaller number is 120. What is the product?
Step-by-step explanation:
90 and 10x=90
y=10
Explanation:
Let x be equal to the first number.
Let y be equal to the second number.
We know that the sum of the two numbers is 100, so we can say that x+y=100.
We also know that the difference of the two numbers is 80, so we can also say that x-y=80
And now we have our two equations:
x+y=100
x-y=80
To find x and y, we first solve for one of the variables and plug it into one of the two equations to solve for the other. In this case, the easiest way to approach this question is to add both of the equations to cancel y out and solve for x (please check the picture attached for a better representation).
x+y=100
x-y=80
-> 2x=180
2x=180
Divide both sides by 2
2x/2=180/2
x=90
Now that we have found the value of the first number, x, we can plug it in to either of our two original equations to solve for y.
x+y=100
90+y=100
Subtract both sides by 90
90+y-90=100-90
y=10
Therefore, the value of x is 90 and the value of y is 10. Their sum is 100 and their difference is 80.

I spent $120 shopping for food last week. This week I spent 12% more.
Which expression could be used to find how much I spent on food this
week?
Answers
Answer:
$120*.12= then add the answer to the money amount
Step-by-step explanation:
Answer: 120*1.12
The multiplier 1.12 represents the idea of increasing by 12%
This is because 100% + 12% = 1 + 0.12 = 1.12
For example, if you spend $100 this week and increase that by 12%, then you'll spend 100*1.12 = 112 dollars next week. Note how 12% of 100 is 12, which is the amount the budget goes up.

What is an equation of the line that passes through the point (-5,-4) and is perpendicular to the line 5x+6y=36
Answers
Answer:
y = 6/5x + 2
Step-by-step explanation:
First let's fix this equation
5x + 6y = 36 (subtract 5x on both sides)
6y = -5x + 36 (divide by 6 on both sides)
y = -5/6x + 6
NOW
The perpendicular slope of this equation is 6/5
Now we have to plug in (-5,-4) to get the y-intercept
-4 = 6/5(-5) + b (distribute 6/5 to -5) (b represents the y-intercept)
-4 = -6 + b (add 6 on both sides)
2 = b
So your equation is...
y = 6/5x + 2

Answers
Given the diagram given where lines n and p are parallel, and transversals r and s are perpendicular, the measure of angle 1 is: [tex]\mathbf{1) 51^{\circ}}[/tex]
The angle measure where two perpendicular lines intersect each other equals 90 degrees.
Therefore, the angle formed as shown in the figure attached, where transversals r and s meet = 90 degrees.
Since lines n and p are parallel lines, therefore:
[tex]m \angle 1 + 90 = 141[/tex] (alternate interior angles are equal)
Subtract 90 from each side[tex]m \angle 1 = 141 - 90\\\\\mathbf{m \angle 1 = 51^{\circ}}[/tex]
Therefore, given the diagram given where lines n and p are parallel, and transversals r and s are perpendicular, the measure of angle 1 is: [tex]\mathbf{1) 51^{\circ}}[/tex]

Two of the points, (2, 1) and (2, 4), have the same x-value. When a single input has multiple outputs, the relation is not a function.
If you were to draw a vertical line at x=2, it would intersect the relation in more than one place. Thus, we say the relation "fails the vertical line test." A vertical line will never intersect the graph of a function in more than one place.

Scientists are preparing two satellites to be launched. The equation y = 8000.C represents the number of miles, y, that the satellite, Space Explorer B, flies in hours.

The rate of speed is the rate at which the total distance is traveled in the time taken.
The Space Explorer B travel 6.67 times faster than Space Explorer A.
What is rate of speed?
The rate of speed is the rate at which the total distance is traveled in the time taken. Rate of speed can be given as,
[tex]s=\dfrac{d}{t}[/tex]
Here, [tex]d[/tex] is the distance traveled by the object and [tex]t[/tex] is time taken but the object to cover that distance.
Given information-
The equation given in the problem is,
[tex]y=8000[/tex]
Here, [tex]y[/tex] represented the number of miles that the satellite, Space Explorer B, flies in hours.
The satellite, Space Explorer A, flies 24000 miles in 20 hours.
The speed of the Space Explorer A, which flies 24000 miles in 20 hours is,
[tex]s=\dfrac{24000}{20}\\s=1200[/tex]
Thus the Space Explorer A, travels 1200 miles per hour.
As the Space Explorer B, travel is 8000 miles per hour and the Space Explorer A, travels 1200 miles per hour. Thus the ratio of the speed of both is,
[tex]d=\dfrac{8000}{1200} \\d=6.67[/tex]
Thus the Space Explorer B travel 6.67 times faster than Space Explorer A.

The x- intercept is (7/5,0)
Hope this helps!
Answer:
(0, -7), (7/5, 0)
Step-by-step explanation:
rearrange your equation to look like y = mx+b where b is the y-intercept
y-3 = 5(x-2) distribute
y-3 = 5x-10 add 3 to both sides
y = 5x -10 +3 combine like terms
y= 5x-7 so
y-intercept is at ( 0, -7)
to find x-intercept make 5x-7=0 and solve for x
5x-7 = 0 add 7 to both sides
5x = 7 divide both sides by 5
x=7/5 or 1.4
x-intercept is (7/5, 0)

Therefore COL = 65
COM is a 90 degree angle since MOD is 90 degrees
COM - COL = 90 - 65 = 25
5y = 25
y=5
LOB = 90
5y + 3x + 23 = 90
5(5) + 3x +23 = 90
25 + 3x + 23 = 90

3x= 90 - 48
3x = 42
x= 14
Answer:
x = 14, y = 5
