on rectangle defg, d is located at -1,-1 , F is located at 4,-8 what is length of ge
Answers
Answer:
[tex]ge= \sqrt{74}[/tex]
Step-by-step explanation:
Given
[tex]d = (-1,-1)[/tex]
[tex]f =(4,-8)[/tex]
Required
Length of ge
The length of ge is the same as the length of df. So, we start by calculating distance gf
[tex]D = \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}[/tex]
This gives:
[tex]D = \sqrt{(-1-4)^2+(-1+8)^2}[/tex]
[tex]D = \sqrt{(-5)^2+7^2}[/tex]
[tex]D = \sqrt{74}[/tex]
This implies that:
[tex]df = \sqrt{74}[/tex]
[tex]ge= \sqrt{74}[/tex]
The number of people who like a particular video online triples every day after the day the video is posted. If 15 people like the video on the day it is posted, which inequality can be used to find the number of days, t , it takes for the number of people who have liked the video to reach more than 3,000?
Answers
Answer:
[tex]t > 5[/tex]
Step-by-step explanation:
Given
[tex]a = 15[/tex] ---- Initial
[tex]r = 3[/tex] --- rate
Required
The inequality that represents people more than 3000
The given parameters show a geometric sequence and will be calculated using:
[tex]T_t = ar^{t-1[/tex]
Where t is the number of days
For the people to be more than 3000, the expression becomes:
[tex]ar^{t-1} > 3000[/tex]
Substitute values for a and r
[tex]15 * 3^{t-1} > 3000[/tex]
Divide both sides by 15
[tex]3^{t-1} > 200[/tex]
Take log of both sides
[tex]Log3^{t-1} > Log200[/tex]
Apply law of logarithm
[tex](t-1)Log3 > Log200[/tex]
Make t - 1 the subject
[tex]t - 1 > \frac{Log200}{Log3}[/tex]
[tex]t - 1 > 4.82[/tex]
Add 1 to both sides
[tex]t - 1 +1> 4.82 +1[/tex]
[tex]t > 5.82[/tex]
Round down
[tex]t > 5[/tex]

help me
Answers
Answer:
x = -10
Step-by-step explanation:
2(x+3) = x-4 --> multiply (x+2) times 2
2x+6 = x - 4 --> subtract x from both sides
x+6 = -4 --> subtract 6 from both sides
x = -10
Answer:
x = -10
Step-by-step explanation:
Simplify both sides of the equation.
2 (x+3) = x − 4
(2) (x) + (2) (3) = x + −4 (Distribute)
2x + 6 = x + − 4
2x + 6 = x − 4
Subtract x (1x) from both sides
2x + 6 − x = x − 4 − x
x + 6 = − 4
Subtract 6 from both sides
x + 6 − 6 = − 4 − 6
x = -10

membership = 20
book cost = 3 x number of books
t = 20 + 3b
Answer:
The answer would be 3b + 20 = t
Step-by-step explanation:
I think the question is referring to the total cost per month to be a member.
Since it costs 20$ monthly no matter what, that price will always stay the same per month.
However, it also costs $3 per book purchased. This price may not always stay the same, because you could buy a different number of books each month, and the price would be different. The cost for books depends on the number of books you buy, which is not stated in the question.
That is why you replace the number of books with a variable, in this case b.
So the equation would be 3b + 20 = t , with 3 being the cost per book, b being the number of books, 20 being the monthly cost, and t being the total amount per month.
In a vegetable market, all cantaloupes are on sale for 70% off the original price. If a single cantaloupe has an original price of $2.60, what is the sale price?
Answers
Answer:
$0.78
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 2.6 × 70/100
Discount = 2.6 x 0.7
You save = $1.82
Final Price = Original Price - Discount
Final Price = 2.6 - 1.82
Final Price = $0.78

B. 2 and 6
C. 4 and 2
D. 1 and 7
Answers
Answer:
1 and 7
Step-by-step explanation:
Given that,
The parallel lines j and k are cut by a transversal l.
We need to find the pair of angles are alternate interior angles.
Angles that are on opposite sides of the transversal and are in between the other two lines are alternate angles.
In this figure, angles 1 and 7 form alternate interior angles. Hence, the correct option is (D).

Step-by-step explanation:
We need to find the slope intercept form first. So far we have this: y=-5x+b. We could plug in the x value and y value to get this : -1=-5(1)+b. b=4. Now we have the slope intecept form: y=-5x+4, and we could turn it into point slope form.
The number of hours per week that the television is turned on is determined for each family in a sample. The mean of the data is 31 hours and the median is 27.2 hours. Twenty-four of the families in the sample turned on the television for 16 hours or less for the week. The 7th percentile of the data is 16 hours.
Step 1 of 5: Based on the given information, determine if the following statement is true or false. The 54th percentile is less than 26 hours.
Step 2 of 5: Approximately how many families are in the sample? Round your answer to the nearest integer.
Step 3 of 5: Based on the given information, determine if the following statement is true or false. Approximately 200 families turned on their televisions for less than 35 hours.
Step 4 of 5: What is the value of the 50th percentile?
Step 5 of 5: Based on the given information, determine if the following statement is true or false.The first quartile is greater than or equal to 20 hours.
Answers
Answer:
Step-by-step explanation:
The mean of the data is 31 hours and the median of the data 27.2 hours.
24 of the families in the sample turned on the television for less than 16 hours for the week.
The 7th percentile = 16 hours
Step 1:
The median is a value that divides the whole data into two equal parts. It implies that the median represents the 50th percentile of the data.
Given that the median is 27.2 hours, thus the 54th percentile should be greater than 27.2 hours.
Thus, the given statement is false.
Step 2:
Let assume that N is the total number of families
24 of the families in the sample turned on the television for less than 16 hours for the week.
The 7th percentile = 16 hours
It means that 7% of N = 24
N = 24/0.07
N = 343
Step 3:
From (2), N = 343
Given that median= 27.2 hours.
It means 200 families turned on their television for less than 27.2 hours.
We don't know if this is true for 35 hours. 100 families may use less than 35 hours and 200 may use more than 35 or vice versa. In addition to that, even 50 families might use less than 35 and 350 may use more than 35 hours.
Hence, the statement is false.
Step 4:
The median is the 50th percentile value which is = 27.2 hours
Step 5:
The statement is false
The 25th percentile is the first quarter of the data and if the 7th percentile is 16 hours, then the 25th percentile should be greater than that.

Step-by-step explanation:
if kevin get paid for 3 hours, then you would multiply $14 by 3. you would end up with $42, then the weekly allowance is $21. then by adding $21 to the $42 we have you would get $63. then a bus ride costs $2.50 and since he rode it 6 times you would multiply $2.50 by 6, which would equal $15. Then subtracting $15 from the $63, you would end up with $48, and then by dividing the total amount for the dinner each time bought, so $12/$48 would equal to 4 times.

The distance between (3,1) and (0,1) is 2. So option C is the right answer. The distance can be calculated by using formula Distance= Sq.root (x2-x1)^2+(y2-y1)^2)
Given two points are (3,1) and (0,1)
What is the formula for distance when two points are given?Distance= Sq.root (x2-x1)^2+(y2-y1)^2)
Here x2=1, x1=3, y2=1, y1=0
Distance=Root (1-3)^2+(1-1)^2
=sq.Root(4)
The root of 4 is 2
=2
Therefore distance between (3,1) and (0,1) is 2
