Answer:
x = 1/6
Step-by-step explanation:
Rewrite the equation to get 5/x = 30. Multiply x on both sides to get 5 = 30x. Then divide 30 on both sides to get your x value which is 1/6.
Answer:
x= 1/6
Step-by-step explanation:
multiply both sides by x
divide both sides by 30
simplify 5/30 to 1/6
What is the common ratio for the sequence:
28, 14, 7, 3.5...
Answer:
r = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
The common ratio r is calculated as
r = [tex]\frac{14}{28}[/tex] = [tex]\frac{7}{14}[/tex] = [tex]\frac{3.5}{7}[/tex] = [tex]\frac{1}{2}[/tex]
Answer:
1/2 is the common ratio of the sequence
Jacoby is using a bucket to collect nuts from a nut tree. He then dumps the bucket into a barrel for shipping of the nuts. He notices that 1 over 5 bucket of nuts fills 2 over 3 of the barrel.
Write and solve an equation to find the number of buckets that will fill the entire barrel. Be sure to define your variable and show your work. Explain your answer in words. (10 points)
Answer:
You need 3/10 buckets of nuts to fill the barrel.
Step-by-step explanation:
We know that 1/5 of a bucket of nuts, fills 2/3 of the barrel.
Then how much we need to fill the other 1/3 of the barrel?
1/3 = (2/3)/2
Then we need half of 1/5 buckets of nuts, this is:
(1/5)/2 = 1/10 buckets of nuts.
Then we need in total:
1/5 + 1/10 buckets of nuts.
we can multiply and divide the left fraction by 2, to get:
(2/2)*(1/5) + 1/10 = 2/10 + 1/10 = 3/10
You need 3/10 buckets of nuts to fill the barrel.

I hope this helps, and Happy Holidays! :)
Answer:
You bought 3 items.
Step-by-step explanation:
All we have to do is multiply $0.75, the amount of the cost of the item, by the amount that you paid.
So:
0.75 × 2.25 = 3

Round to the nearest tenth?
Answer: last option. 9.2
Step-by-step explanation:
The pythagoreon theorm tells us, a^2+b^2 = c^2. We can substitute these values, so 7^2 + 6^2 = x^2 => 49+36 = x^2 => root of 85. The root of 85 is 9.219 something so you can round 9.219 to 9.2.

The slope of the table is:
Let x represent the number of acres and y represent the bushels of wheat. The equation for this relationship is:
Answer:
Y=28x
Step-by-step explanation:
Divide 420/15 224/8 140/5 which will equal 28 as the constant rate.
so, y=28x. It would be y=kx but k =the constant so 28 will fill that spot in.
Y=28x
Is it possible to construct a triangle with side lengths of 6 cm, 11 cm, and 13 cm? Why or why not?
A.
No, because 6 + 11 < 13.
B.
Yes, because 6 + 11 ≠ 13.
C.
No, because 6 + 11 = 13.
D.
Yes, because 6 + 11 > 13.
Answer:
B. Yes, because 6 + 11 ≠ 13.
Step-by-step explanation: So for this one, you have to add two numbers and if the third number is bigger it is a possible construct but if it less than the third number than it is not a possible construct. So 6+ 11 = 17 (its good so far) 11 + 13 = 24(its good so far) 13 + 6 = 19( its good so far) everything checks out that means B is right. And also it is not D because that is saying 6 + 11 is less than 13 which is wrong. Hope this helps someone :)
Consider the problem: After charging for 1/3 of an hour, a phone is at 2/5 of its full power. How long will it take the phone to charge completely? Decide whether each equation can represent the situation.
Answer:
Equation 2
is the answer
Step-by-step explanation:
To calculate the time for a full charge, you would divide the time already charged by the amount of charge:
1/3 / 2/5 = 1/3 x 5/2 = 5/6 of an hour for full charge.
You could use 2 and 4 to find the time.

During second period, Kiera completed a grammar worksheet. Of the 90 questions, she got 70% right. How many questions did Kiera get right?
Answer:
we conclude that Kiera got the right 63 questions.
Step-by-step explanation:
Total questions = 90
The percentage of correct question = 70%
Using the formula
The number of correct questions = 70% of 90
= [70/100] × 90
= 0.7 × 90
= 63
Therefore, we conclude that Kiera got the right 63 questions.

A new health drink has 120% of the recommended daily allowance (RDA) for a certain vitamin is 40 MG. How many milligrams of the vitamin are in the drink?
Answer:
We conclude that the number of milligrams of the vitamin in the drink will be: 48 mg
Step-by-step explanation:
The amount of certain Vitamin = 40 mg
Given that a new health drink has 120% of the recommended daily allowance (RDA) for a certain vitamin is 40 MG.
Thus,
The number of milligrams of the vitamin in the drink:
120% of 40
= [120/100] × [40]
= 1.2 × 40
= 48
Therefore, we conclude that the number of milligrams of the vitamin in the drink will be: 48 mg

Harry catches the train from Belfast to Dublin at 4pm. The average speed of the train is 70 mph and the distance between Belfast and Dublin is 105 miles. What time does Harry arrive in Dublin?
Answer:
[tex]Arrival\ Time = 5:30\ pm[/tex]
Step-by-step explanation:
Given
[tex]Current\ Time = 4pm[/tex]
[tex]Speed = 70mph[/tex]
[tex]Distance = 105miles[/tex]
Required
Determine the arrival time
First, we calculate the time taken from Belfast to Dublin using:
[tex]Speed = \frac{Distance}{Time}[/tex]
Substitute values to the expression.
[tex]70 = \frac{105}{Time}[/tex]
Cross Multiply
[tex]70 * Time = 105[/tex]
[tex]Time = \frac{105}{70}[/tex]
[tex]Time = 1.5\ hour[/tex]
Arrival time is then calculated as:
[tex]Arrival\ Time = Current\ Time + Time\ Taken[/tex]
[tex]Arrival\ Time = 4pm + 1.5\ hour[/tex]
[tex]Arrival\ Time = 5:30\ pm[/tex]
Suppose you were told that the company built the fence in 4 hours and that they completed 1.6 mile of the fence each hour. How would you use the double number line to help you find the length of the fence?
Solution :
It is given that the time required by a company to built the fencing = 4 hours
The length of fenced completed in 1 hour = 1.6 mile
Now by using the double number line to find the length of the fence, we would :
-- We have to draw two parallel straight lines.
-- Let the 1st line represents the time measured in hours and the 2nd line represents the distance or length measured in miles.
-- Mark four marks of equal spacing in both the line so that each mark represents 1 hour in the 1st line and each mark in the 2nd line represents the corresponding lengths.
-- Now in hour, they completed 1.6 miles, therefore from the double number line, we can see that in 4 hours, they completed 4.6 miles of fencing.
Hence the length is 4.6 miles.
Which of these shows the result of using the first equation to substitute for y in the second equation, then combining like terms?

A wireless company offers two cell phone plans. For the month of September, Plan A charges $35 plus $0.25 per minute for calls. Plan B charges $20 plus $0.50 per minute for calls. For what number of minutes do both plans cost the same amount?
Answer:
60 minutes
Step-by-step explanation:
Let the number of minutes be represented as x
For Plan A
Plan A charges $35 plus $0.25 per minute for calls.
$35 + $0.25 × x
35 + 0.25x
For Plan B
Plan B charges $20 plus $0.50 per minute for calls.
$20 + $0.50 × x
20 + 0.50x
For what number of minutes do both plans cost the same amount?
This is calculated by equating Plan A to Plan B
Plan A = Plan B
35 + 0.25x = 20 + 0.50x
Collect like terms
35 - 20 = 0.50x - 0.25x
15 = 0.25x
x = 15/0.25
x = 60 minutes.
Hence, the number of minutes that both plans cost the same amount is 60 minutes
