Answer:
The age of the mother is 42 years, while the age of the girl is 7 years.
Step-by-step explanation:
Given that 1/6 of the age of a mother is the age of her daughter, to determine the age of the mother if the difference of their age is 35, the following calculations must be performed:
6 - 1/6 = 5/6
5/6 = 35
35/5 = 7
7 + 35 = 42 = 7 x 6
7 = 7 x 1
Therefore, the age of the mother is 42 years, while the age of the girl is 7 years.

To the nearest tenth of a percent, what percent of the 7th grade students were in favor of wearing school uniforms?
A. 19.2%
B. 41.3%
C. 42.9%
D. 57.1%
Answer:
C. 42.9%
Step-by-step explanation:
They say out of 7th grade so we need the total 7th graders which is 112 and they say in favor so then we take 48 and divide the two 48/112 which gives us a decimal so we then multiply it by 100 to get the percent.
48/112= 0.429
0.429(100)= 42.9%
The percent of the 7th grade students were in favor of wearing school uniforms is 42.9%
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
We have,
Total students in 7th grade = 112
Students who favor school uniforms = 48
So, the percent of the 7th grade students were in favor of wearing school uniforms is
= 48 /112 x 100
= 0.4285 x 100
= 42.85 %
= 42.9%
Thus, the required percentage of student is 42.9%.

Desirae made 138 cookies this week. She baked 2 more than 4 times the total she made last week. How many cookies did she bake last week?
Answer: 34 cookies baked last week
Step-by-step explanation:
138=4x-2
136=4x
34=x
Answer:
34 cookies!
Step-by-step explanation:
If we say the number of cookies that Desirae baked last week was 'x', we can make the following equation for how many she baked this week: 4x+2=138. Here are the following steps to solve for x:
4x=138-2=136
x=34
Therefore she baked 34 cookies last week.

A box contains 5 red balls, 6 white balls and 9 black balls. Two balls are drawn at
random. (The first ball is not replaced). Find the probability that both balls are of
the same colour
Answer:
[tex]P(Same)=\frac{61}{190}[/tex]
Step-by-step explanation:
Given
[tex]Red = 5[/tex]
[tex]White = 6[/tex]
[tex]Black = 9[/tex]
Required
The probability of selecting 2 same colors when the first is not replaced
The total number of ball is:
[tex]Total = 5 + 6 + 9[/tex]
[tex]Total = 20[/tex]
This is calculated as:
[tex]P(Same)=P(Red\ and\ Red) + P(White\ and\ White) + P(Black\ and\ Black)[/tex]
So, we have:
[tex]P(Same)=\frac{n(Red)}{Total} * \frac{n(Red) - 1}{Total - 1} + \frac{n(White)}{Total} * \frac{n(White) - 1}{Total - 1} + \frac{n(Black)}{Total} * \frac{n(Black) - 1}{Total - 1}[/tex]
Note that: 1 is subtracted because it is a probability without replacement
[tex]P(Same)=\frac{5}{20} * \frac{5 - 1}{20- 1} + \frac{6}{20} * \frac{6 - 1}{20- 1} + \frac{9}{20} * \frac{9- 1}{20- 1}[/tex]
[tex]P(Same)=\frac{5}{20} * \frac{4}{19} + \frac{6}{20} * \frac{5}{19} + \frac{9}{20} * \frac{8}{19}[/tex]
[tex]P(Same)=\frac{20}{380} + \frac{30}{380} + \frac{72}{380}[/tex]
[tex]P(Same)=\frac{20+30+72}{380}[/tex]
[tex]P(Same)=\frac{122}{380}[/tex]
[tex]P(Same)=\frac{61}{190}[/tex]

please help i need the number of visita
answer
x=28
explanation
so what would happen is you pay a fee of 22$ and then 1$ per visit and we are looking to see how many visits it take to get to 50$
what we do it put
22+x=50
x is how many visits it would take to 50$
so what we do is subtract 22 from both sides
x=50-22
x=28

The Equation of line is y= 1/3 x + 2.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
Given-
The points through which line passes (0, 2) and (6, 4).
So, the Slope of the line,
m = (4- 2)/ (6-0)
m= 2/6
m= 1/3

A researcher wants to know if drinking beer makes a person more attractive to mosquitos. 120 people were recruited to partake in this experiment. Each person was randomly assigned to either drink beer or to ingest water. The subject after drinking their beverage was seated close enough so that odor from the individual would be detectable by the mosquitoes (note that the mosquitoes could not actually touch the humans). The researcher then recorded whether or not the mosquito flew toward the subject (assumed flying toward person meant they were attracted to them). 68 people were assigned to drinking beer, while the other 52 were assigned to drinking water. Out of the 68 who drank beer 43 of them had a mosquito fly toward them, while 26 of those who drank water had a mosquito fly toward them. (This is based loosely off an experiment performed by Lefevre et al. (PLOS ONE, 2010)).

Find the x- and y- intercepts of the equation -x+5y=10.
Answer:
X Intercept: (-10,0), Y Intercept: (0,2)
Step-by-step explanation:
Well, firstly you need to rewrite the equation to make it easier. After rewriting it you have the equation y=x/5+2 by adding the x to the right side and dividing everything by 5. Now simply plug in your zeroes in their respective places. For the x intercept, your y value must equal 0 so we have the equation 0=x/5+2. After solving it, x must be -10 in order for our y value to be 0 getting us for the x intercept (-10,0). For the y intercept, your x value must equal zero so you simply subsitute zero in the equation for x which I will do here: y=0/5+2. If our x value is zero, consequently, our y value will be 2 getting us for the y intercept, (0,2).

Find the general solution of the differential equation and check the result by differentiation. (Use C for the constant of integration.)
[tex]\frac{dy}{dx}[/tex] = 4x^1/6
Answer:
For this we can first multiply both sides by dx:
[tex]dy = 4x^{1/6}dx[/tex]
Next we can integrate both sides:
[tex]\int dy = \int 4x^{1/6}dx\\[/tex]
We can then solve both integrals to get:
[tex]y = 4(\frac{6}{7}x^{\frac{7}{6}}+C_1) = \frac{24}{7}x^{\frac{7}{6}}+C_2[/tex]
We can just say the constant is C2. So the answer is
[tex]y = \frac{24}{7}x^{\frac{7}{6}}+C_2[/tex]
We can also check this by differentiating both sides. We will ultimately get the equation we with. If I made any mistakes or misread something, please let me know.
