Jacob has 6.15 meters of rope. He is going to use 1.2 meters of rope to tie up his boat. How many centimeters of rope does he have left?
Answers
Answer:
495 cm
Step-by-step explanation:
Remark
When you do the subtraction, whatever is left (the decimal part) is the length in cm when multiplied by 100.
Solution
Remaining rope = starting length - what was used.
Remaining rope = 6.15 - 1.2
Remaining rope = 4.95 meters
Answer
The remaining rope = 4.95 * 100 = 495 cm

A grocer has two kinds of tea: one selling for 80 cents a pound and the other selling for 60 cents a pound. How many pounds of each kind must be used to make 50 pounds worth 74 cents a pound?
Answers
Answer:
35 pounds of tea for 80 cents.
Step-by-step explanation:
Equation::
value + value = value
80x + 60(50-x) = 74*50
80x + 60*50 - 60x = 74*50
20x = 14*50
x = 35 lbs (amt. of 80 cent tea to use)
50-x = 15 lbs (amt. of 60 cent tean to use)
Answer:
35 pounds of tea for 80 cents.
15 pounds of tea for 60 cents.
Step-by-step explanation:
x · 80 + y · 60 = 50 · 74
x + y = 50 · (- 60)
80x + 60y= 50 · 74
- 60x - 60y = -50 · 60
20x = 50 · (74-60) = 50 · 14
x = 50 · 14/20
35 pounds of tea for 80 cents.
y = 50 - 35 =
15 pounds of tea for 60 cents.

Population of Jacksonville was 3810 and 2010 and is growing at an annual rate of 3.5% if the growth rate continues what will the approximate population in 2023
Answers
Answer:
FV= 5,958.67 = 5,959
Step-by-step explanation:
Giving the following information:
Current population (Present Value)= 3,810
Growth rate (g)= 3.5% annual
Number of periods (n)= 13 years
To calculate the future number of people (FV), we need to use the following formula:
FV= PV*(1+i)^n
FV= 3,810*(1.035^13)
FV= 5,958.67 = 5,959
Give an example of a linear function whose graph intersects with the y-axis at the same points as the graphs of the following functions.
y= x+11
y= -9x-6
Answers
Answer:
Given functions:
y= x + 11y= -9x - 6They have different y-intercepts, therefore the line to intersect y-axis at the same points is y-axis itself.
The equation is:
x = 0The graph is attached
---------------------------------------
Note. If the question is about the lines above separately, then the answer is following
The first line has y-intercept of 11, any line with same y-intercept is the answer:
y = mx + 11, where m ≠ 1For the second line the equation is:
y = mx - 6, where m ≠ -9Answer:
y = mx + 11, where m ≠ 1
For the second line the equation is:
y = mx - 6, where m ≠ -9
Which value is a solution for the equation tan x/2 = -1?
A. 5pi/4
B. 7pi/4
C. 3pi/4
D. 3pi/2
Answers
Answer:
D
Step-by-step explanation:
What we have to do is to find the arc tan
x/2 = arc tan (-1)
tan is negative on the 4th and second quadrant
arc tan (-1) = 135 or 315
pi is 180 degrees
so we have;
135 is 3 pi/4
multiplied by the 2
= 6 pi/4 which is 3 pi/2
315 is 7 pi/4 which is same as 7 pi/2 when we multiply by 2

Just put in the equation on desmos. An ellipse will pop-up
The conic section is represented by the following equation –5x^2 + 9xy + 5y^2 + 6x – 4y + 11 = 0 is circle.
We have given that the equation of the equation is,
–5x^2 + 9xy + 5y^2 + 6x – 4y + 11 = 0
What is the general formula of the ellipse?The general formula of the circle is
[tex]ax^2+2xy+by^2+2fx+2gy+c=0[/tex]
Compare the given equation with the general formula of the circle so we get the equation of the circle
Therefore the equation of the circle is –5^+ 9xy + 5y^2 + 6x – 4y + 11 = 0

x² - 14x + 49
= x² - 2 * x * 7 + 7²
= ( x - 7) ²
Hope it will help :)
Answer:
49
Step-by-step explanation:
What two numbers add to the middle term and multiply to the last term? 49 doesnt fit in to 14 at all so we know that one of the factors is 7. since the middle term is -14, you would add -7 to -7 to get that. so we know the factors of the middle term are -7 and -7, so all you have to do is multiply them together. It would be positive 49.

Answer: You'll have a quadrilateral with the following points
(5, -5)(4, -7)(6, -7)(8, -3)A diagram is posted below.
===================================================
Explanation:
The given quadrilateral has four unmarked points. I'll add the point labels A,B,C,D such that
A = (-3, 3)B = (-5, 2)C = (-5, 4)D = (-1, 6)I started at the lower right corner and worked my way clockwise.
----------------
Let's shift the line y = x-2 up two units so that it moves to y = x
We'll need to shift every point of the quadrilateral up two units as well.
So we have these new point locations after the shifting has occurred.
A' = (-3, 5)B' = (-5, 4)C' = (-5, 6)D' = (-1, 8)----------------
Now we need to reflect over the diagonal line. The rule to reflect over the line y = x is as simple as swapping the x and y coordinates.
So we can say [tex](x,y) \to (y,x)[/tex]
A point like (-3, 5) moves to (5, -3)
We have these new locations
A'' = (5, -3)B'' = (4, -5)C'' = (6, -5)D'' = (8, -1)----------------
The last thing to do is to shift everything down 2 units. This is to undo the first step we did when we shifted everything up by 2 units.
Doing this leads to these locations
A''' = (5, -5)B''' = (4, -7)C''' = (6, -7)D''' = (8, -3)Check out the diagram below.

Given that 198 = 2 x 3² x 11 and 90 = 2 x 3² x 5,

b) the largest integer that is a factor of both 198 and 90
(pls show working ty :) )
Answers
9514 1404 393
Answer:
a) 22
b) 18
Step-by-step explanation:
a) In order for 198k to be a perfect square, all of its integer factors must be squares. 3² is already a factor. To make the other factors be squares, need to multiply by 2 and 11. That is, k = 2×11 = 22. Then we will have ...
198k = 2×3²×11 × (2×11) = 2²×3²×11² = (2×3×11)²
k = 22
__
b) The factors that are different in the two numbers are 11 and 5. The factors that are the same are 2×3² = 18.
18 is the greatest common factor of 198 and 90
