Answer:
9500
Step-by-step explanation:
Scientists tagged 950 pike for a research project about a local lake. Later, they trapped 100 pike, of which 10 had tags. To the nearest whole number, what is the best estimate for the pike population?
The best estimate of a population is calculated as:
= N = mn/k
Where N = Estimate of the population
m = 950 pike
n = 100 pike
k = 10 tags
= 950 × 100/10
= 9500
The best estimate of he population = 9500

how do you write a linear equation that relates y to x
Answer:
Find the slope and y-intercept of the line. = −2 Because the line crosses the y-axis at (0, 3), the y-intercept is 3. So, the linear function is y = −2x + 3. Use the graph or table to write a linear function that relates y to x.

What is the area of a square if its side length is 1 173 cm?
Answer:
The number 173 or 1,173?
1,173 x 1,173 = 1,375,929
Since all sides are equal in a square, one given length would be all the side lengths since all sides are equal in a square.
If the side length was 173 then:
173 x 173 = 29,929

Y=1/5x+14 when b=7? how do i solve this?
Answer:
Step-by-step explanation:
Y = 1/5 x + 14 where b = 7
Result:
x + 70 = 5 Y
Geometric figure:
line
Alternate forms:
x = 5 Y - 70
x - 5 Y + 70 = 0
Real solution:
Y = x/5 + 14
Solution:
Y = x/5 + 14
Integer solution:
x = 5 n, Y = n + 14, n element Z
Solution for the variable x:

Perform the indicated operation and simplify. (x+3)(x2−5x+2) Write your answer in standard form. No spaces when entering your answers. For this question, you will have to use the carrot key ^ for an exponent and the carrot key is found by pressing "shift" and "6". For example, 42 would be entered as 4^2
Answer:
x^3-2x^2-13x+6
Step-by-step explanation:
We are to simplify the expression (x+3)(x^2−5x+2). This is as shown;
(x+3)(x^2−5x+2)
Expand
= x(x^2)-5x(x)+2x+3x^2-3(5x)+6
= x^3 - 5x^2+2x+3x^2-15x+6
Collect the like terms
= x^3 - 5x^2+3x^2+2x-15x=6
= x^3-2x^2-13x+6
This gives the required expression

Challenge A new coffee shop sold cups of hot coffee and cups of iced coffee during its first two days. The ratio of cups of hot coffee sold to cups of iced coffee sold on the first day was . On the second day, the shop sold as many cups of iced coffee as the first day. The ratio of cups of hot coffee sold to cups of iced coffee sold on the second day was . How many cups of each type of coffee did the shop sell each day?
Answer:
1 day = 221 hot coffee cups and 117 iced coffee cups
2 day = 247 hot coffee cups and 234 iced coffee cups
Step-by-step explanation:
A new coffee shop sold 468 cups of hot coffee and 351 cups of iced
coffee during its first two days. The ratio of cups of hot coffee sold to cups of
iced coffee sold on the first day was 17 : 9. On the second day, the shop sold
twice as many cups of iced coffee as the first day. The ratio of cups of hot
coffee sold to cups of iced coffee sold on the second day was 19 : 18.
a) How many cups of each type of coffee did the shop sell the first day?
Let cups of hot coffee be denoted by x
Then
17x+ 19x= 468
or
36x= 468
x= 13
On the first day the number of hot coffee cups sold are 17y or 17*13= 221 cups.
On the second day the number of hot coffee cups sold are 19y or 13*19= 247 cups.
Similarly Let cups of iced coffee be denoted by y
Then
9y+18y= 351
27y= 351
y= 351/27= 13
On the first day the number of iced coffee cups sold are 9y or 13*9= 117 cups.
On the second day the number of iced coffee cups sold are 18y or 13*18= 234 cups.

Answer:
Area = 117 sq. ft.Perimeter = 44 feetStep-by-step explanation:
Given,
Length of the bedroom = 13 feet
Width of the bedroom = 9 feet
Therefore,
First Case:
Area of the bedroom = Length × Width
= 13 feet × 9 feet
= 117 sq. ft.
Second Case:
Perimeter of the bedroom = 2(Length + Width)
= 2 (13 + 9) feet
= 2 × 22 feet
= 44 feet
Hence,
Required area of the bedroom is 117 sq. ft. and perimeter of the bedroom os 44 feet (Ans)
Write an equation of the line that passes through the points ( 2,6) and (- 8, 1)
Answer:
[tex]y = \frac{1}{2} x+5[/tex]
Step-by-step explanation:
1) First, find the slope of the line that passes between the two points. Substitute the x and y values of (2,6) and (-8,1) into slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Then, solve:
[tex]m = \frac{(1)-(6)}{(-8)-(2)} \\m = \frac{1-6}{-8-2} \\m = \frac{-5}{-10} \\m = \frac{1}{2}[/tex]
So, the slope is [tex]\frac{1}{2}[/tex].
2) Now, write the equation of the line using the point-slope formula, [tex]y-y_1 = m (x-x_1)[/tex]. Substitute real values for [tex]m[/tex], [tex]x_1[/tex], and [tex]y_1[/tex].
Since [tex]m[/tex] represents the slope, substitute [tex]\frac{1}{2}[/tex] in its place. Since [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects, substitute the x and y values of one of the given points into the formula as well. (Any of the two will do. Either choice will represent the same line. I chose (2,6).) Then, isolate y to put the equation in slope-intercept form and find an answer:
[tex]y-6 = \frac{1}{2} (x-2)\\y-6 = \frac{1}{2} x-1\\y = \frac{1}{2} x+5[/tex]

-5x+4y=7 y=-2x-8
x = 13, y = 18
hope this is right
Answer:
x=−3 and y=−2
Step-by-step explanation:
-5x+4(-2x-8)=7
-13x-32=7
-13x-32+32=7+32
-13x=39
divide both sides by -13
x=-3
substitute x for -3
-2(-3)-8= -2
y= -2
Workout plus offers a membership for $30 each month plus a $100 startup fee. Fit Works offers a membership for $50 each month plus a $20 startup fee. After how many months will memberships to both gyms cost the same amount?
Answer:
4 months
Step-by-step explanation:
Let
x = number of months
Workout plus = 100 + 30x
Fit works = 20 + 50x
After how many months will memberships to both gyms cost the same amount?
Equate the cost of both gyms
Workout plus = Fit works
100 + 30x = 20 + 50x
100 - 20 = 50x - 30x
80 = 20x
x = 80/20
x = 4 months
After 4 months, memberships to both gyms cost the same amount
