Answer 1

Answer:

(1/4)c59=t g/3016/cb+350w+20c/55+2t 4d+2p

Answer 2

Step-by-step explanation:

2) 1/4

3) 59 - t

4) g/30

5) 16/c

6) b-3

7) 50w +20(make sure of this from others)

8) c/5

9) 2t +5

10) 4d +2p

Explanation:

2) 1 - 3/4 =1/4

________

3)56 on bus, t people get out, 3 get on bus

So add 56 with 3(people get on bus) and put minus t

56 +3 - t

59 - t

________

4) class: 30 students where g is number of girls

So girls fraction is their number over the total number..

Girls = g/30

________

5) class: c students where 16 is no of boys(no=number)

So boys fraction is their no over the total

Boys: 16/c

________

6) b people are on the bus, 7 people get out, and 10 get on

Add who is in the bus now and then put minus who get out because 7 is substracted from b

So, b-7+10 => b + 3

Or b+10 - 7 =>b + 3

________

8) i have c chocolates that i distributed them between 5 friends then you divided what you have from chocolate between 5 friends : c divide 5 => c/5

________

9) i already have 5 pens. Ok

Someone gives me 2 packs of pencils and each pack has t pens

(t represents number of pens in each pack)

So, if one pack has t pens then 2 packs has 2t pens. And add the 5 pens i already have with 2t pens

2t +5

________

10)each deer has 4 legs then d deers have 4d legs. (multiply 4 by number of deers)

Also, each pheasant has 2 legs then p pheasants have 2p legs.

(multiply 2 legs by number of pheasants, you will get 2p legs)

Now, add the number of legs of d deers and p pheasants that we calculated it above:

Number of Legs of d deers + number of Legs of p pheasants

= 4d legs + 2p legs

= 4d + 2p

brook has 3,250 in her savings account. she plans to save an additional 175 each month. Brook wrote a linear function to represent y, the total amount of savings after x months. what did she do wrong?

4= 175(x + 3,250)

Answers

she forgot y and put x in the wrong spot

The 4 should be the Y (she forgot it), and the X is in the wrong spot (should be 175x). The solution should be y= 175x+3250.

Question 1
Find the mean and median of the data.

4,6,7,9,6,4,5,6,8,10
mean:

median:

Answers

Answer:

Mean: 6.5

Median: 6

Mode: 6

Range: 6

Minimum: 4

Maximum: 10

Step-by-step explanation:

The mean is the same as the average value of a data set and is found using a calculation. Add up all of the numbers and divide by the number of numbers in the data set.

The median is the central number of a data set. Arrange data points from smallest to largest and locate the central number. This is the median. If there are 2 numbers in the middle, the median is the average of those 2 numbers.

The mode is the number in a data set that occurs most frequently. Count how many times each number occurs in the data set. The mode is the number with the highest tally. It's ok if there is more than one mode. And if all numbers occur the same number of times there is no mode.

Mean is 6.5 and median is 6

An American traveling in Japan wishes to exchange American money for Japanese money. If the exchange rate is $1 = 80 yen, then how many dollars will the traveler need to purchase 10,000yen?

Answers

Answer: $125

Step-by-step explanation:

1/80=x/10,000

10,000/80=125

Hope this helped!

Answer:125 yen

Step-by-step explanation:
Ratio and proportion

Ratio=1:80=x:10,000

x represents dollars which is unknown

1/80=x/10,000

Then you cross multiply

80x=10,000

80x/80=10,000/80

x=125

Therefore,$125 will give you 10,000yen

Point A, located at (5, -4) is reflected in the y-axis, resulting in the location of point A'. Which of the following statements is true?

Point A' is located at (-5,-4)
Point A' is located at (-5,4)
Point A is located at (4,5)
Point A' is located at (-4,5)

Answers

The correct answer is Point A' is located at (-5, -4).

When a point is reflected in the y-axis, its x-coordinate is negated and its y-coordinate remains the same. Therefore, the x-coordinate of point A changes from +5 to -5, and the y-coordinate remains -4. Hence, the coordinates of A' are (-5, -4).

Point A’ is located at (-5,-4)

Step-by-step explanation:

The measures of the angles of △DEF are in the ratio 2:4:4. What are the measures of the angles?

The measures of the angles of △XYZ are in the ratio 4:5:6. What are the measures of the angles?

Answers

Answer:

A) 18

B) 48 , 60 and 72

Step-by-step explanation:

A) since the angles are in ratio 2:4:4 there is a constant proportionality that we call k. So the angles can be represented by 2k,4k and 4k. That means 2k + 4k + 4k = 180. K=18

B) The angles would add up to 180 as a general rule, make x the multiplier and

4x+5x+6x=180

15x=180

X=12

Then

4(12)=5(12)+6(12)=180

48, 60 and 72

what is the average between (25,28.8,39.2,51.2,64.8,80)? Please help me!

Answers

Answer:

48.17

Step-by-step explanation:

Average = sum of numbers / number of numbers

Sum of numbers = 25 + 28.8 + 39.2 + 51.2 + 64.8 + 80 = 289

Number of numbers = 6

Average = 289 / 6 = 48.17

Average/Mean = 25+28.8+39.2+51.2+64.8+80 /6

=>average = 289/6 = 48.167

( since average = sum of observations divided by number observations)

Answer:

\(f^{-1}\left(f(576)\right)=\boxed{576}\)

\(f^{-1}(-7)+f(-7)=\boxed{13}\)

Step-by-step explanation:

The inverse of an invertible function with the domain of all real numbers is obtained by reflecting the original function across the line y = x, which swaps the input and output values of the function. Therefore, (x, y) → (y, x).

Given table:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&-7&11&-13&6&5&-9\\\cline{1-7}\vphantom{\dfrac12}f(x)&7&12&8&-7&13&5\end{array}\)

Inverse function:

\(\begin{array}{lrrrrrr}\vphantom{\dfrac12}x&7&12&8&-7&13&5\\\cline{1-7}\vphantom{\dfrac12}f^{-1}(x)&-7&11&-13&6&5&-9\end{array}\)

If we have a function f(x), the inverse function is denoted as f⁻¹(x), and it has the property that f⁻¹(f(x)) = x for all valid inputs x in the domain of f(x).

Therefore:

\(\large\boxed{f^{-1}\left(f(576)\right)=576}\)

The value of f(-7) is the value of f(x) when x = -7. Therefore, reading from the original table, f(-7) = 7.

The value of f⁻¹(-7) is the value of f⁻¹(x) when x = -7. Therefore, reading from the inverse function table, f⁻¹(-7) = 6.

Therefore:

\(\large\boxed{\begin{aligned}f^{-1}(-7)+f(-7)&=6+7\\&=13\end{aligned}}\)
