whats the distance between (1,2) and (4,-2)
Answer:
5 units
Step-by-step explanation:
Distance formula:
[tex]\sqrt{(x2-x1)^2 + (y2-y1)^2}[/tex]
Square root of those quantities. x2 and x1 mean the x values from one coordinate and the other, and the same goes for the y-coordinates. So y2-y1 represents (-2) - (2) and x2-x1 = (4) - (1). The answers you get (-4 and 3, respectively), now have to be squared, then added together. So (-4)^2 = 16 and (3)^2 = 9. Add 16 and 9 together you get 25. Final answer, you square root 25 and you get 5. Technically the square root of 25 is both positive and negative 5, but you cannot get a negative number for distance in this case (vectors are different).
At a certain college, the ratio to men to women is 5 to 4. If there are 2,800 men, how many women are there?
Answer:
2240
Step-by-step explanation:
braniest pls
there are 2,240 women at the college.
To find the number of women at the college, we can use the ratio of men to women given and the known number of men.
The ratio of men to women is 5 to 4, which can be expressed as 5/4.
If we know that there are 2,800 men, we can set up a proportion:
5/4 = 2,800/x
To solve for x, the number of women, we cross-multiply:
5x = 4 * 2,800
5x = 11,200
Dividing both sides by 5:
x = 11,200 / 5
x = 2,240
Therefore, there are 2,240 women at the college.

Your sister is selling Girl Scout cookies that cost $3.50 per box. Your family bought 6 boxes. How many more boxes of
cookies does your sister need to sell to raise $196?
Answer:
She needs $175.
Step-by-step explanation:
3.50 X 6= $21. (196-21=175)
So since she needs $196 and per box it would be $3.50 and 6 boxes is $21 total, she would need to sell 56 boxes total to get to her goal, but since her parents bought 6 boxes already she will only need 50 more.

A trapezoid has a base of 4.5 inches, a height of 6 inches, and an area of 21 square inches. The equation below can be used to determine b2, the length in inches of the second base of the trapezoid.
12(4.5+b2)(6)=21
Answer:
[tex]b_2 = -2.5[/tex]
Step-by-step explanation:
Given
[tex]\frac{1}{2}(4.5 + b_2) * 6 = 21[/tex]
Required
Determine the value of T
[tex]\frac{1}{2}(4.5 + b_2) * 6 = 21[/tex]
Multiply both sides by 2
[tex]2 * \frac{1}{2}(4.5 + b_2) * 6 = 21 * 2[/tex]
[tex](4.5 + b_2) * 6 = 42[/tex]
Divide through by 6
[tex]4.5 + b_2 = 42/6``[/tex]
[tex]4.5 + b_2 = 7[/tex]
[tex]b_2 = 7 - 4.5[/tex]
[tex]b_2 = -2.5[/tex]

You are about to graph the linear equation y=1/4x+8 but you need to determine the scale of the x and y axes first. Select the best option for a scale for both the x-axis and y-axis (one of each). A) x scale of -5 to 5 B) x scale of -15 to 15 C) y scale of 0 to 15 D) y scale of -30 to 30 (10 POINTS AND BRAINLIST IF RIGHT WILL REPORT WRONG ANSWERS)
Answer:
B) x scale of -15 to 15
C) y scale of 0 to 15
Step-by-step explanation:
The change in y-value is 1/4 of the change in x-value, and the y-intercept is 8. That means a y-scale of -30 to 30 would not be well-utilized over a small range of x. (It would take an x-range of about 200 to make much use of that y-scale.)
An appropriate y-scale is one that has 8 near its middle. The corresponding x-scale is then roughly ±4 times half the y-scale. The closest choices are ...
-15 ≤ x ≤ 15 . . . . choice B
0 ≤ y ≤ 15 . . . . . . choice C
The amount of memory available on an iPhone seems like it doubles with each new version. If this is true, and the first version had 4 gigabytes of memory, how much memory does the 10th version have?
Answer:
40
Step-by-step explanation:
Multiply 10 by 4 which 4 represents the starting Iphone memory storage and then 10 represents the value of memory for the 10th model.
By solving the exponent, we find that the 10th version will have 2048 gigabytes of memory.
What are exponents?An exponent is a number that is placed as a superscript over a number. In other words, it indicates that the base is raised to a certain power.

The amount Ricky charges for his lawn service varies directly with the number of hours it takes to complete the job. If Ricky charges $112.50 for a 3-hour job, how much money would he charge for a 5-hour job?
The charge for a 5-hour job will be $187.5.
What is Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
Ricky charges $112.50 for a 3-hour job.
Now,
Since, Ricky charges for 3 hour job = $112.50
Hence, The charges for 1 hour job = $112.50 / 3
= $37.5
So, The charges for 5 hour job = 5 x $37.5
= $187.5
Thus, The charge for a 5-hour job will be $187.5.

The difference of 8 times a number and 2
Read the conjecture below. Select all of the true statements about this conjecture. If you multiply two numbers, then the product is greater than either number. Select all that apply. a. This conjecture is true. For example, (7)(4) = 28. The product of 28 is greater than 7 and greater than 4. b. This conjecture is false. There is a counterexample that would prove this conjecture false. c. This conjecture is false: . d. There is not enough information.
Answer:
a. This conjecture is true. For example, (7)(4) = 28. The product of 28 is greater than 7 and greater than 4
b. This conjecture is false. There is a counterexample that would prove this conjecture false.
Step-by-step explanation:
The conjecture is true because, if we multiply two numbers, then their product is greater than either number. As given in the example, 7 × 4 = 28. 28 is greater than both 7 and 4.
Also, if we multiplied a fraction by a whole number, the result would be less than one of the numbers. For example 1/2 × 4 = 2. 2 is greater than 1/2 but not 4. So, the conjecture is false.
If we multiply two fractions, the result is less than both fractions. For example 1/2 × 1/4 = 1/8. 1/8 is less than both 1/2 and 1/4. So, the conjecture is false.
The precious two examples show that there are counterexamples which prove that the conjecture is false although it is true sometimes.
Rationalise the denominator and simplify 6/√3

Step-by-step explanation:
Given,
6/√3
The denominator is √3.
We know that
The rationalising factor of √a is √a. To rationalise the denominator of 6√√3, we multiply this by √3/√3.
⇛(6/√3)×(√3/√3)
⇛(6√3)/(√3)²
⇛(6√3)/(√3*3)
⇛(6√3)/3
