Answer:
120 to 180
Step-by-step explanation:
Answer:
2:3
Step-by-step explanation:
There were 300 children in total. Of those 300, 120 are boys. To find out the number of girls, subtract 120 from 300 to get 180.
300 - 120 = 180 girls
Total: 300 || Boys: 120 || Girls: 180
Next, simply imput the numbers into your ratio.
120:180
Then, to get the shortest answer, simplify the two numbers by dividing them.

Step-by-step explanation:
Since we believe it
The number sequence is that those which can be described as [tex]\frac{p}{q}[/tex] and that is not ending and recurring. Figures that are unreasonable are also the ones, that are not [tex]\frac{p}{q}[/tex] and therefore are non-ending, non-recurring.
The number sequence is [tex]3\sqrt{25} = 3 \times 5 = 15[/tex]
Rational amount since it is classified as [tex]\frac{p}{q}[/tex] .[tex]\frac{-11}{151}[/tex] is really a rational number.
[tex]1.\overline{1.625}[/tex] is a real function, since it does not end but repeats it.
The rational number [tex]\sqrt {256} = 16[/tex]
Unreasonable number [tex]\sqrt{141}[/tex].

Answer:
30 feet
Step-by-step explanation:
For this problem we can use ratios 6:4 and x:20. We can also write these ratios as fractions 6/4 and x/20 or 3/2 and x/20. Set the two fractions equal to each other and solve for x:
3/2 = x/20
1.5 = x/20
30 = x

An object is traveling at a steady speed of 10 1/5 mi/h. How long will it take the object to travel 1 4/5? First round to the nearest integer to find the estimated answer. Then find the exact answer
Answer: [tex]2\dfrac13\ h[/tex]
Step-by-step explanation:
Given: Speed = [tex]10\dfrac15[/tex] mi/h [tex]=\dfrac{21}{5}[/tex]mi/h
Distance need to be travel = [tex]1\dfrac45[/tex] miles [tex]=\dfrac{9}{5}[/tex] miles
[tex]speed=\dfrac{distance}{time}\\\\\Rightarrow\ time=\dfrac{distance}{speed}[/tex]
[tex]\Rightarrow\ time =\dfrac{\dfrac{21}{5}}{\dfrac{9}{5}}\\\\\Rightarrow\ time =\dfrac{21}{9}\\\\\Rightarrow\ time =\dfrac{7}{3}\\\\\Rightarrow\ time =2\dfrac13\ h[/tex]
Hence, time taken to travel = [tex]2\dfrac13\ h[/tex]

Answer:
RP = 2.3
PQ = 1.0
RQ = 2.3
Step-by-step explanation:
The pictures says RP = RQ,
so:
3x - 0.4 = x + 1.4
this you can simplify to:
x = 0.9
Then fill x in:
RP = 3*0.9 - 0.4 = 2.3
PQ = 0.9 + 0.1 = 1.0
RQ = 2.3
Which property is shown in this example?
(6.3 + 5.2) + 8.7 = 6.3 + (5.2 + 8.7)
A. Identity Property
B. Commutative Property
C. Associative Property
D. Distributive Property
Answer:
associative property
Step-by-step explanation:
identity property is when you multiply one by any number and get the number you multiplied by. for example, 1x3=3; 1x7=7. Commutative property has to do with the order of multiplication being rearranged. and distributive property multiplies a number outside the parentheses into the numbers inside. all that's left is the associative property which indicates that addition can be rearranged and still get the same answer. hope this helps :)

Currently James has $600 in his bank account, while Lisa has $500 in hers.
Every Friday afternoon James withdraws $15. At the same time Lisa withdraws $12 knowing that she can't spend as much as James.
Will their account balances ever be equal? If they are ever equal, how many weeks will it take?
Answer:
Their account balances will never be equal.
Step-by-step explanation:
I basically ran the math. 500 minus 12 times anything from 1-40 cannot equal 600 minus 15 times anything from 1-40. When we come to 600 - (15*40) we get zero.
Don't shame I'm just trying to pass, my assignment's weigh 35% of my grade, right now my assignment percentage is 65%. My test which holds 45% of my grade is at 85% and my final is 20%, which I got a 90 on. If I take 7 0's in assignments, what would my grade be? Basically asking how many 0's under assignments can I basically take so I do not fail. Hope this makes sense
Answer:
Step-by-step explanation:
Let's start by weighing everything but the assignments. We'll get back to them momentarily.
You have 85% on 45% of your grade. That's 38.25
Your final weighs in at 20%. You have. 18
So your total so far is 56.25
Now that looks mighty low, but we haven't put in the assignments yet.
So by the time you are finished you will have done 41 out of 48 assignments and that means you have done (41/48)*100 = 85.41 of the work. On these assignments that you have done, you averaged 65%
So your assignment mark will be 0.65 * 85.41 = 55.52
The weighted average = 0.35
The mark you will get is 0.35 * 55.52 = 19.32
So your final grade will be 56.25
Grade 75.57

i have to find the mean and range of this data set and show work.
data set: 49,50,52,58,61,63,66,67,67,68
Answer:
61 is the mean and the range is 19
Step-by-step explanation:
trust
Mean = [tex]60.1[/tex] and Range = [tex]19[/tex] for the given set of data.
What is Mean?
"Mean is the average set of all the given values."
What is Range?"Range is the difference between highest and the lowest value."
Formula
Mean = [tex]\frac{Sum of all the observations}{Total number of observations}[/tex]
Therefore, Mean = [tex]\frac{49 + 50 +52 +58 +61 +63 +66 +67 +67 +68}{10}[/tex]
= [tex]\frac{601}{10}[/tex]
= [tex]60.1[/tex]
Range = Max (x) - Min (x)
= [tex]68 - 49[/tex]
= [tex]19[/tex]
Hence, the Mean = [tex]60.1[/tex] and Range = [tex]19[/tex] for the given data set.

Suppose that F(x) = x^2 and G(x)=3x^2 +8. Which statement best compares
the graph of G(x) with the graph of F(x)?
* look at picture* please put right answer
Answer:
ur screwed go with b
Step-by-step explanation:
Answer:B The graph of g(x) is the graph of f(x) compressed vertically. The factor of compression is 2/5 and is less than 1 so it is compressed instead of stretch if the factor was greater than 1. There is no reflection across the x-axis because there is no negative sign in front of the function f(x).

Factor out 2x squared minus 98 completely
Answer:
2(x+7)(x-7)
Step-by-step explanation:
1. In 2x^2-98, there is a common factor of 2
2. The equation therefore becomes 2 (x^2 - 49)
3. We know that x^-49 is a difference of two squares and can therefore be factored into (x+7)(x-7)
4. Therefore the fully factored answer is 2(x+7)(x-7)

When a point passes through a line it satisfies its equation
(X-x0 )m= y-y0
Slope = m = -2
(X-2 )(-2)=y-3

What is the answer to
3-h=8
Hello!
[tex]\large\boxed{h = -5}[/tex]
3 - h = 8
Isolate for h by subtracting 3 by both sides:
3 - 3 - h = 8 - 3
- h = 5
Multiply both sides by -1 to make h positive:
-h(-1) = 5(-1)
h = -5
is either x = 5 or x = 15 a solution to 25 - x =5?
