Answer:

D. John's boat was farther and faster

Step-by-step explanation:

The equation tells you that at x = 0, Roberta's boat was 10 miles from the dock. The words tell you John's boat started 20 miles from the dock, so his boat started farther away.

John's boat traveled a distance of (55 -20) = 35 miles in 5 hours, so the speed was (35 mi)/(5 h) = 7 mi/h. The equation tells you Roberta's boat traveled 6 miles for each hour, so John's boat was faster.

John's boat was farther and traveled more quickly

Additional comment

The variables in Roberta's equation are not defined. In order for the problem to make sense, we must assume that x represents time in hours, and y represents distance in miles.

A square shed has a floor area of 156.25m square. what is the length of the diagonal

slava [35]

Square root 156.25 to get the values of the sides of the square. You will get 12.5m for each side.

Now that you have the side values, use Pythagoras' Theorem to solve for the diagonal. Let's call the diagonal x,

c^2 = a^2 + b^2
x^2 = 12.5^2 + 12.5^2
= 312.5

Square root both sides to get x,

x = 17.68m (2 d.p)

HOPE THIS HELPED! Ask me if there is anything you don't understand from this working :D

Given the midpoint and one endpoint of a line segment, find the other endpoint.

neonofarm [45]

Answer:

(-12 , 2)

Step-by-step explanation:

GIVEN :-

Co-ordinates of one endpoint = (-4 , -10)
Co-ordinates of the midpoint = (-8 , -4)

TO FIND :-

Co-ordinates of another endpoint.

FACTS TO KNOW BEFORE SOLVING :-

Section Formula :-

Let AB be a line segment where co-ordinates of A = (x¹ , y¹) and co-ordinates of B = (x² , y²). Let P be the midpoint of AB . So , by using section formula , the co-ordinates of P =

$(x , y) = (\frac{x^2 + x^1}{2} ,\frac{y^2 + y^1}{2} )$

PROCEDURE :-

Let the co-ordinates of another endpoint be (x , y)

So ,

$(-8 , -4) = (\frac{-4 + x}{2} , \frac{-10 + y}{2} )$

First , lets solve for x.

$=> \frac{x - 4}{2} = -8$

$=> x - 4 = -8 \times 2 = -16$

$=> x = -16 + 4 = -12$

Now , lets solve for y.

$=> \frac{y - 10}{2} = -4$

$=> y - 10 = -4 \times 2 = -8$

$=> y = -8 + 10 = 2$

∴ The co-ordinates of another endpoint = (-12 , 2)

Carlos told t-shirts and had to the festival. he made a $3 profit for each t-shirt he sold. he also made a profit of $45 from se

MA_775_DIABLO [31]

The answer is 16 shirts. (in the equation below, x represents how many shirts he sold.)
We can solve this question by using this equation: 3x + 45 = 93
The next step would be to subtract 45 from both sides, which would leave us with 3x=48.
Then, we must divide both sides by 3. This means 3x divided by 3 = 48 divided by 3. This leaves us with x = 16 shirts.
