cevap =560...........
A boat traveled 240 miles downstream and back. The trip downstream took 12 hours. The trip back took 24 hours. What is the speed of the boat in still water? What is the speed of the current?
Answer:
rate boat = 15 mph
rate current = 5 mph
explanation:
d = r * t
t = d/r
240 / (r_boat + current) = 12 Multiply both sides by r_boat + r_current.
240 = 12(r_boat + current)
240/ (r_boat - current) = 24 Multiply both sides by r_boat - r_current
240 = 24*(r_boat - current)
Since the distances are the same in both equations, you can equate the right side of each.
12 (r_boat + current) = 24(r_boat - current) Divide by 12
r_boat + current = 2 (r_boat - current) Remove the brackets.
r_boat + current = 2*r_boat - 2* current add 2 currents to both sides
r_boat + 3currents = 2*r_boat Subtract r_boat both sides
3 currents = r_boat.
240 = 12*(r_boat + current. Divide by 12
20 = r_boat + current Put 3 currents in for r_boat
20 = 3currents + 1 current Combine
20 = 4 currents Divide by 4
5 = current
The rate of the current = 5 miles / hour
3 currents = r_boat
3*5 = rate_boat
15 = rate of the boat
Branden and Janna are analyzing the same conditional statement. Branden finds multiple examples that validate the conditional statement. Janna finds one example that satisfies the hypothesis of the conditional statement, but not the conclusion. Which must be true? The conditional statement is true.

Find three consecutive even integers such that the sum of the smallest and the largest is 36.
Answer:
Step-by-step explanation:
The consecutive even integers are (2n-2), (2n), and (2n+2), where n is an integer.
(2n-2) + (2n+2) = 36
4n = 36
n = 9
(2n-2) = 16
(2n) = 18
(2n+2) = 20

If f (x) = - 9x + 8, then find f (-2)
Answer:
26
Step-by-step explanation:
f(x) = -9x + 8
f(-2)
______________
When we have a function f(x), x can be plugged in with anything, when plugged, the equation the function f(x) is tied too will also have x replaced with the value.
Therefore, if f(x) equals f(-2), -9(-2) + 8
Multiply :
-9(-2) + 8
18 + 8

Answer:
the area of the shape is 7.14
Step-by-step explanation:
First, find the area of the square:
2 in x 2 in = 4 in
then to find the area of the semi- circles add them together to make a circle
To find the area of the circle, use:
pi x radius^2
Since the diameter is 2 divide the diameter by 2 to get radius
3.14 x 1^2 = 3.14
The circle is 3.14 plus 4 ( the square ) = 7.14

Work out the coordinates of the midpoint of AB
Answer:
a) It is clear that point A is located at x = -2, and y = -1, therefore, the coordinates of point A are: A(-2, -1)
b) We can plot the point B (-2, 4) on the grid at x = -2 and y = 4.
Please check the attached graph.
c) The coordinates of the midpoint of AB: [tex]\left(-2,\:\frac{3}{2}\right)[/tex]
Step-by-step explanation:
Part a)
Important Tip:
The coordinates of point A can be determined by checking the location of point A.It is clear that point A is located at x = -2, and y = -1, therefore, the coordinates of point A are:
A(-2, -1)Part b)
We can plot the point B (-2, 4) on the grid at x = -2 and y = 4.
Please check the attached graph.
Part c)
We can determine the coordinates of the midpoint of AB using the formula
[tex]M.P_{AB}=\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]
In our case, we have:
A(x₁, y₁) = A(-2, -1)
B(x₂, y₂) = B (-2, 4)
so substituting [tex]\left(x_1,\:y_1\right)=\left(-2,\:-1\right),\:\left(x_2,\:y_2\right)=\left(-2,\:4\right)[/tex] in the formula
[tex]M.P_{AB}=\left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]
[tex]=\left(\frac{-2-2}{2},\:\frac{4-2}{2}\right)[/tex]
Refine
[tex]=\left(-2,\:\frac{3}{2}\right)[/tex]
Therefore, the coordinates of the midpoint of AB: [tex]\left(-2,\:\frac{3}{2}\right)[/tex]

Nell's mortgage is $50,150 at 10 percent for 30 years.
What is her monthly payment if she must pay $8.78 per $1,000?
Answer:
The correct option is a.
Step-by-step explanation:
It is given that Nell's mortgage is $50,150 at 10 percent for 30 years and she must pay $8.78 points per $1,000.
EMI on $1000 is $8.78, so EMI on $1 is
EMI on $1 = 8.78/1000 = 0.00878
EMI on $50150 is
EMI on $50150 = 0.00878 x 50150 = 440.317 = 440.32
Therefore the correct option is a.
