Answer:
enlarge the picture 7 times by inches
To enlarge Tonya's picture by a factor of 7, the length of 4 1/5 inches is multiplied by 7 to get an enlarged length of 29 2/5 inches.
Tonya has a small picture with a length of 4 1/5 inches. To enlarge the picture by a factor of 7, we need to multiply the original length by 7. First, we convert 4 1/5 inches to an improper fraction: 4 1/5 = (4 * 5 + 1)/5 = 21/5. Next, we multiply by 7: (21/5) * 7 = 21 * 7 / 5 = 147/5 inches. To convert it to a mixed number, we divide 147 by 5 which equals 29 with a remainder of 2, leading to a mixed number of 29 2/5 inches. Thus, the enlarged picture has a length of 29 2/5 inches.
if a frog can move 1/4 of a mile every hour, then how many hours would it take for a frog to go 2 miles?
Answers
Answer: 8 hours
Step-by-step explanation: If a frog can jump 1/4 fourth a mile every hour then it will take 4 hours to complete a mile. But because we are talking a bout 2 miles, you have to double the time. Therefore, the answer is 8 hours
It would be one hour every quarter of the mile so count the hours by the amount of numbers there are in one mile so it would be 8 hours

What value of x would make the expression below equal to 8? Photo provided! 20points!
Answers
For this case, we must find the value of "x" so that the given expression is equal to 8.
That is to say:
[tex](\sqrt [5] {8 ^ 3}) ^ x = 8[/tex]
We apply "ln" to both sides of the equation to remove the exponent variable:
[tex]ln ((\sqrt [5] {8 ^ 3}) ^ x) = ln (8)\\xln (\sqrt [5] {8 ^ 3}) = ln (8)\\xln (\sqrt [5] {512}) = ln (8)[/tex]
We rewrite 512 as:
[tex]512 = 32 * 16 = 2 ^ 5 * 16\\xln (\sqrt [5] {2 ^ 5 * 16}) = ln (8)[/tex]
By definition of power properties we have:
[tex]\sqrt [n] {a ^ m} = a ^ {\frac {m} {n}}[/tex]
So:
[tex]xln (2 \sqrt [5] {16}) = ln (8)[/tex]
We clear x:
[tex]x = \frac {ln (8)} {ln (2 \sqrt [5] {16})}[/tex]
In decimal form, [tex]x = 1.6[/tex] periodic number
ANswer:
[tex]x = \frac {ln (8)} {ln (2 \sqrt [5] {16})}\\x = 1.6\ periodic\ number[/tex]

Which expression can be used to find 80% of 20
Answers
When you say Percent, you really mean per 100. So percentage is the result you get when multiplying a quantity by a percent. To find 80% of 20, we can use the following expression:
[tex]20\times \frac{80}{100}=16[/tex]
That is the product of 80 and 20 divided by 100, which is 16.
Answer:
The correct answer is
80% of 20 = 16
Step-by-step explanation:
points to remember
x% of y is given by
(x/100) * y
To find 80% of 20
Let 'x' be the 80% of 20 then we can write,
x = (80/100) * 20
x = (8/10) * 20
= 8 * 2 = 16
Therefore 80% of 20 is 16
The correct answer is 16
How to find the area of a triangle on a coordinate plane
Answers
Equation of Area of Triangle = 1/2 x b x h
Find the base by counting the boxes across the bottom.
Find the height by counting the boxes from the base (bottom) to highest point on the triangle.
Insert those numbers into the equation and you get your answer.
To find the area of a triangle on a coordinate plane, you can use the formula: Area = 1/2 * base * height. The base can be any side of the triangle, and the height is the perpendicular distance from the base to the opposite vertex. We can calculate the lengths of the base and height by using the coordinates of the triangle's vertices.
Explanation:To find the area of a triangle on a coordinate plane, we can use the formula: Area = 1/2 * base * height. The base can be any side of the triangle, and the height is the perpendicular distance from the base to the opposite vertex. We can calculate the lengths of the base and height by using the coordinates of the triangle's vertices.
For example, if the coordinates of the vertices are (x1, y1), (x2, y2), and (x3, y3), we can find the length of the base by calculating the distance between (x1, y1) and (x2, y2). Then, we can find the height by calculating the distance between (x3, y3) and the line containing the base. Finally, we substitute the values of the base and height into the formula to find the area.
Suppose the coordinates of the triangle are (1, 2), (4, 6), and (7, 2). We can find the base and height as follows:
Base: Distance between (1, 2) and (4, 6) = sqrt((4 - 1)^2 + (6 - 2)^2) = sqrt(9 + 16) = sqrt(25) = 5 unitsHeight: Distance from (7, 2) to the line containing the base (1, 2) and (4, 6) = perpendicular distance from (7, 2) to the line = 2 units (since the line is parallel to the x-axis)Now, substitute the values into the formula: Area = 1/2 * base * height = 1/2 * 5 * 2 = 5 units^2. Therefore, the area of the triangle is 5 square units.

a sociologist develops a test to measure attitudes towards public transportation and 27 randomly selected subjects are given the test.their mean score is 76.2 and their standard deviation is 21.4. construct the 95% confidence interval for the mean score of all such subjects
Answers
Answer:
The 95% confidence interval for the mean score is:
[tex]\mu[/tex] ∈ [tex](67.73,\ \ 84.67)[/tex]
Step-by-step explanation:
We want to estimate the population mean, that is, the average score of all the subjects.
An estimator for the population mean μ is [tex]{\displaystyle {\overline {x}}}[/tex]
Since the sample size is [tex]27 <30[/tex] then we use the statistic [tex]t_{\frac{\alpha}{2}}[/tex] with [tex]27-1 = 26[/tex] degrees of freedom
The confidence interval for the mean is:
[tex]({\displaystyle {\overline {x}}} + t_{\frac{\alpha}{2}}\frac{S}{\sqrt{n}},\ \ {\displaystyle {\overline {x}}} - t_{\frac{\alpha}{2}}\frac{S}{\sqrt{n}})[/tex]
Where
[tex]{\displaystyle {\overline {x}}}=76.2[/tex] is the average score of the sample
[tex]S=21.4[/tex] is the standard deviation of the sample
[tex]n= 27[/tex] is the sample size
[tex]t_{\frac{\alpha}{2}} = 2.056[/tex] for a confidence level of 95% and 26 degrees of freedom
Then confidence interval is
[tex](76.2 + 2.056\frac{21.4}{\sqrt{27}},\ \ {76.2 - 2.056\frac{21.4}{\sqrt{27}})[/tex]
[tex](76.2 + 8.467,\ \ 76.2 - 8.467)[/tex]
[tex]\mu[/tex] ∈ [tex](67.73,\ \ 84.67)[/tex]
The 95% confidence interval for the mean score of attitudes towards public transportation is (68.13, 84.27), calculated using the formula for a confidence interval.
Explanation:In this scenario, we would use the formula for a 95% confidence interval, which is the sample mean ± (1.96 * (standard deviation / √n)). In this case, n is 27 (the sample size), the sample mean is 76.2, and the standard deviation is 21.4.
Firstly, calculate the standard error by dividing the standard deviation by the square root of n:
SE = 21.4 / √27 ≈ 4.12
Then multiply the standard error by 1.96:
1.96 * SE ≈ 1.96 * 4.12 ≈ 8.07
Finally, add and subtract this value from the sample mean to get the confidence interval:
76.2 ± 8.07 gives an interval of (68.13, 84.27).
So, we can be 95% confident that the true population mean of attitudes towards public transportation lies between 68.13 and 84.27.

Recycling center a processes aluminum at rate of 100 pounds per hour, while recycling center b processes aluminum at a rate of 2 tons per week. Assuming that both centers operate all day every day, which center processes aluminum faster, and why?
Answers
Answer:
Center a processes it faster
Step-by-step explanation:
Center B math: 2 tons as pounds is 4000 pounds.
4000/7=571.43 pounds a day
571.43/24=23.81 pounds a hour
23.81 pounds per hour is less than 100 pounds an hour. so center a is the faster one.
Answer:
Center A process aluminium faster
Because
Center A process 8.4 Tons of aluminium per week while center B processes 2 tons per week
Step-by-step explanation:
Topic: Unit Conversion
Given
Center A Rate of Processing Aluminium
A = 100 pounds per hour
Center B Rate of Processing Aluminium
B = 2 tons per week
To solve this question, the following assumptions will be made
Both centers operate 24 hours a dayBoth centers operate 7 days a weekHaving said that, the first step is to make conversions.
We either convert pounds to tons or tons to pounds.
Converting Center A Rate of Processing Aluminium from Pounds to Tons
1 Pound = 0.0005 Tons
So, 100 Pounds = 0.0005 * 100
100 Pounds = 0.05 Tons.
So, Center A Rate of Processing Aluminium is 0.05 Tons per hour
Before we make comparison, both must be in the same unit.
i.e. either in Tons per hour or Tons per units.
Converting Center A Rate of Processing Aluminium from Tons per hour to Tons per week
There are 24 hours a day;
So, Center A Rate of Processing Aluminium is 0.05 Tons/hr* 24 hr/day
Converting Center A Rate of Processing Aluminium is 1.2 Tons / day
There are 7 days a week;
So, Center A Rate of Processing Aluminium is 1.2 Tons/ day * 7 days / week
Converting Center A Rate of Processing Aluminium is 8.4 Tons / week
At this point, we have the following
Center A Rate of Processing Aluminium = 8.4 Tons / week
Center B Rate of Processing Aluminium = 2 tons per week
By Comparison,
8.4 Tons per week is greater than 2 tons per week; So, Center A process aluminium faster

[tex]y=3cos(x-\pi)-4[/tex]
[tex]3 cos((x - \pi ) - 4 = 3 cos(x) - 4[/tex] because [tex]cos(x-\pi) = cos(x)[/tex]
[tex]-1 \leq cos(x) \leq 1[/tex]
[tex]-3 \leq 3cos(x) \leq 3[/tex]
[tex]-3-4 \leq 3 cos(x)-4 \leq 3-4[/tex]
[tex]-7 \leq 3 cos(x)\leq-1[/tex]
The range is -7 to -1 so the midpoint is [tex]\frac{-7-1}{2} =-4[/tex]
Therefore, the equation of the mid-line for the given function is y = -4.
