Step-by-step explanation:
I'm not entirely sure what you mean by "from the origin", but hopefully this helps.
The distance formula for a Cartesian coordinate system (your standard x-y graph) is [tex]d=\sqrt{(x1-x2)^{2}+(y2-y1)^{2}}[/tex].
If you're measuring "from the origin", that just means one of your points is (0,0).
For example, if you were to measure between the origin and the point (1,4) your formula would look like this:
[tex]d=\sqrt{0-1)^{2}+(0-4)^{2}}\\d=\sqrt{(-1)^{2}+(-4)^{2}} \\d=\sqrt{1+16} \\d=\sqrt{17}[/tex]
So, the distance between the origin and (1,4) is [tex]\sqrt{17}[/tex].
I hope this helps! Please let me know if you have any other questions!
Lisa’s school requires each student to earn 75 hours of community service each year. Lisa has already earned 27 hours. She plans to earn the remainder of her hours by volunteering at a nursing home. If Lisa spends 2 hours at the nursing home per visit, which equation represents the number of visits, v, that Lisa will need to make to fulfill her community service requirement?
Answer:
Step-by-step explanation:
2v+27=75
2v=75 - 27
2v=48
v= 24 visits
So, she needs 24 visits

The formula s=12at ^2 is used to calculate the distance s travelled by a bike when a=3 and t=10, each correct to the nearest integer, calculate the lower bound of the distance s
Answer:
Step-by-step explanation:
Given the formula for calculating the distance travelled expressed as;
s=1/2at^2
Given
a = 3
t = 10
Required
lower bound of s
Substitute the given values into the equation;
s=1/2at^2
S = 1/2(3)(10)^2
S = 1/2 * 3 * 100
S = 3 * 50
S = 150
Hence the lower bound of distance S is 150

-1 1/3 plus 3/4 (fraction form)
Answer:
[tex]\boxed{-\frac{7}{12} }[/tex]
Step-by-step explanation:
[tex]-1\frac{1}{3} +\frac{3}{4}[/tex]
→ Make both denominators the same
[tex]-1\frac{1}{3} +\frac{3}{4}=-1\frac{4}{12} +\frac{9}{12}[/tex]
→ Convert mixed number into improper fraction
[tex]-1\frac{1}{3} +\frac{3}{4}=-1\frac{4}{12} +\frac{9}{12}=-\frac{16}{12} +\frac{9}{12}[/tex]
→ Do the -16 + 9 and leave 12 as the denominator
[tex]-1\frac{1}{3} +\frac{3}{4}=-1\frac{4}{12} +\frac{9}{12}=-\frac{16}{12} +\frac{9}{12}=-\frac{7}{12}[/tex]
The required simplification o f[tex]-1\frac{1}{3} +\frac{3}{4}[/tex] into fraction form is -1 / 12
To simplify -1 1 / 3 plus 3 / 4 into fraction form.
The process in mathematics to operate and interpret the function to make the function simple or more understandable called simplifying and the process is called simplification.
What is the fraction?Fraction is defined as the number of compositions constituting the Whole. And it is represented as a / b, where a = numerator and b = denominator.
Since the given problem is
[tex]-1\frac{1}{3} +\frac{3}{4}[/tex]
We need to simplified it into fraction form like a / b.
[tex]=-1\frac{1}{3}+\frac{3}{4} \\= -2/3 + 3/4[/tex]
= ( -8 + 9 ) / 12
= -1 / 12
Thus, The required simplification of [tex]-1\frac{1}{3} +\frac{3}{4}[/tex] into fraction form is -1 / 12.

Answer:C 6x-18
Step-by-step explanation:
3 times 2 equals 6 and 3 times -6 will give you -18
Answer:
The solution is C) 6x-18
Step-by-step explanation:
3(2x-6)
(we multiply between 3 and in brackets)
3×2x = 6x
3×(-6) = -18
if we combine, then the arrangement is like this:

33 managers and 27 non-managers attended a company meeting. What percentage of the people in the meeting were managers?
Answer:
81.82%
Step-by-step explanation:
Step 1: We make the assumption that 33 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$x.
Step 3: From step 1, it follows that $100\%=33$100%=33.
Step 4: In the same vein, $x\%=27$x%=27.
Step 5: This gives us a pair of simple equations:
$100\%=33(1)$100%=33(1).
$x\%=27(2)$x%=27(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
$\frac{100\%}{x\%}=\frac{33}{27}$100%x%=3327
Step 7: Taking the inverse (or reciprocal) of both sides yields
$\frac{x\%}{100\%}=\frac{27}{33}$x%100%=2733
$\Rightarrow x=81.82\%$⇒x=81.82%
Therefore, $27$27 is $81.82\%$81.82% of $33$33.

(5∧3/4)∧2/3
Answer:
[tex]\sqrt{5}[/tex]
Step-by-step explanation:
Since we can see that [tex](5^{\frac{3}{4} } )^{\frac{2}{3} }[/tex] has a parentheses, the exponents are being multiplied by each other.. To find their product, just multiply across..
3*2 = 6/4*3 = 12. So we have 6/12 which can be simplified to just 1/2.
So now we have [tex]5^{\frac{1}{2} }[/tex] which is equal to [tex]\sqrt{5}[/tex]..

Suppose there is a 1.9f drop in temperature for every thousand feet that an airplane climbs into the sky. If the temperature on the ground is 51.8f what will be the temperature when the plane reaches an altitude of 3,000ft??
Answer: 46.1f
Step-by-step explanation:
Simce there is a 1.9f drop in temperature for every thousand feet that an airplane climbs into the sky, when the airplane reaches an altitude of 3,000ft, the drop in temperature will be:
= 1.9f × 3
= 5.7f
Since the temperature on the ground is 51.8f, then the temperature will then be:
= 51.8f - 5.7f
= 46.1f
A survey of all planet Umpt found that 36 beings preferred dubble juice to all the other juices. If 40 being were surveyed all together, what percent of them preferred dubble juice.
Answer:
90%
Step-by-step explanation:

I need to know what the 12th term in the sequence is.
Answer:
61
Step-by-step explanation:
The formula of the sequence given is;
aₙ = -5 + 6(n-1)
problem is to find the 12th term;
a₁₂ = -5 + 6 (12 - 1)
a₁₂ = -5 + 6(11)
a₁₂ = -5 + 66
a₁₂ = 61
Jacob checked two bags of potato chips for broken chips. The first bag
had 6 broken chips, which was 10% of the chips in bag 1. The second bag
had 12 broken chips, which was 25% of the chips in bag 2. How many
total chips were in both bags?
Answer:
3
Step-by-step explanation:
Total 108 chips were in the both bags.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
10% of chips in the first bag is 6.
To find the total chips in the first bag:
6 = 10 x total number of chips in the first bag / 100
total number of chips in the first bag = 600/10
total number of chips in the first bag = 60
25% of chips in the second bag is 12.
To find the total chips in the second bag:
12 = 25x total number of chips in the second bag / 100
total number of chips in the second bag = 1200/25
total number of chips in the second bag = 48
Now, total chips in the both bags = 60 + 48 = 108
Therefore, total 108 chips were in the both bags.
