Answer:
$9
Step-by-step explanation:
Given I owe my friend $16 and my mom owes me $25
step 1-->take back money from mom
Mom gives back you $25
Now you have $25
Step 2: return the money you owe to friend
you owe $16
You have $25 and return $16
Thus , money you will have = money you have - money you return
money you have = $25 - $16 = $9
Thus, you will have $9 , after all is settled.
A kayaker is paddling at a steady rate for 10 miles with the river current. She can only travel 4 miles against the current in the same amount of time. If the rate of the current is 8 miles per hour, what is the kayaker’s rate in still water (without the current)?
Answer: 18.66 miles per hour.
Step-by-step explanation:
The velocity of the Kayak can be written as the velocity of the kayak in still water plus the rate of the current.
If K is the velocity of the kajak, and C the velocity of the current, we have that:
When the kajak moves along with the current, for a given time T.
(K + C)*T = 10mi
when the kajak move against the current:
(K - C)*T = 4mi
now we can replace C by 8mph, and take the quotient of both equations:
((K + 8mph)*T)/(K - 8mph)*T)) = 10mi/4mi
(K + 8)/(K-8) = 10/4
K + 8 = (K- 8)*10/4
K + 8 = K*10/4 - 20
K*10/4 - K = K*6/4 = 20 + 8 = 28
K = 28*4/6 = 18.66
So the rate of the kajak is 18.66 miles per hour.

what are the solutions to the quadratic equation 9x(2) + 64 = 0?
and
what is the factored form of the quadratic expression 9x(2) + 64?
Answer:
Solution of given quadratic equation is
[tex]$ (\frac{8i}{3}, -\frac{8i}{3} ) $[/tex]
Step-by-step explanation:
The given quadratic equation is
[tex]9x^2 + 64 = 0[/tex]
The general form of the quadratic equation is given by
[tex]ax^2 + bx + c = 0[/tex]
Comparing the general form with the given quadratic equation
[tex]a = 9\\b = 0\\c = 64[/tex]
The solutions of the quadratic equation is given by
[tex]$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$[/tex]
Substitute the values of a, b and c
[tex]$x=\frac{-0\pm\sqrt{0^2-4(9)(64)}}{2(9)}$[/tex]
[tex]$x=\frac{\pm\sqrt{-2304}}{18}$[/tex]
[tex]$x=\frac{\pm48i}{18}$[/tex]
[tex]$x=\frac{\pm8i}{3}$[/tex]
[tex]$x=\frac{8i}{3}$[/tex]
and
[tex]$x=-\frac{8i}{3}$[/tex]
Where i represents iota which means that the given quadratic equation has complex roots.
So the solution of given quadratic equation is
[tex]$ (\frac{8i}{3}, -\frac{8i}{3} ) $[/tex]
The factored form of the given quadratic equation is
[tex]$ (x+ \frac{8i}{3}) (x- \frac{8i}{3}) = 0 $[/tex]

Answer:
x = 125
Step-by-step explanation:
all of the angles in a triangle must add up to 180, so 25 + 30 + x = 180. you can subtract 25 and 30 from both sides and you are left with x = 125.
hope it helps!
________________________________
Hey!!!
Solution,
X+30+25=180(Sum of angle in traingle)
or,X+55=180
or,X=180-55
X=125
The value of X is 125.
Hope it helps
Good luck on your assignment

19 is the top and 20 is the bottom what is 19 in a fraction
Answer:
95%
Step-by-step explanation:
you meant what is 19 in a percentage, it means that it is 19/20. So you do 19 divided by 20. Do the math and get .95 ..95=95% .You get this by multiplying te decimal by 100 to find the percentage
Answer:
95%
When it says in percent, just times the fraction by 100
19/20 * 100= 95%
Or ...
You can change it to a decimal and move the decimal point back 2 spaces.
.95 = 95%

Triangle G F H is rotated to form triangle G prime F prime H prime. Which type of transformation maps triangle GFH onto triangle G'F'H'? translation reflection rotation dilation
Answer:
Rotation
Step-by-step explanation:
The type of transformation maps triangle GFH onto triangle G'F'H' will be; Rotation.
How does transformation of a function happens?The transformation of a function may involve any change.
Usually, these can be shift horizontally (by transforming inputs) or vertically (by transforming output), stretching (multiplying outputs or inputs) etc.
If the original function is y = f(x), assuming horizontal axis is input axis and vertical is for outputs.
We are given that Triangle GFH is rotated to form triangle G prime F prime H prime.
Stretching:
Vertical stretch by a factor k: [tex]y = k \times f(x)[/tex]
Horizontal stretch by a factor k: [tex]y = f\left(\dfrac{x}{k}\right)[/tex]

Answer:
Measure of the side, x = 5.25 units
Step-by-step explanation:
Figure B is a scale image of figure A.
That means figure B is an image and figure A is a pre-image.
Scale factor for the dilation from figure A to figure B = 1.75
Scale factor = [tex]\frac{\text{Side of image B}}{\text{Side of pre-image A}}[/tex]
1.75 = [tex]\frac{x}{3}[/tex]
x = 1.75 × 3
x = 5.25 units
Therefore, measure of the side figure B is 5.25 units.

The altitude to the hypotenuse of a right triangle is the geometric mean between the segments on the hypotenuse.
always
sometimes
never
Answer: always
Step-by-step explanation:
A right triangle is a kind of triangle with one right angle.
Side opposite to right angle is known as hypotenuse.Other two sides is known as legs.A theorem of right triangle says that :-
When the altitude drawn from the right angle to the hypotenuse splits the hypotenuse into two sections of segments. Then the length of each leg of the right triangle is the geometric mean of the lengths of the hypotenuse and the segment of the hypotenuse that is adjacent to the leg.Hence, the statement "The altitude to the hypotenuse of a right triangle is the geometric mean between the segments on the hypotenuse." is always true.
Thus , the correct answer is "always".
Your answer should be always :)
