Answer:

3225 miles in 3.5 hours

Step-by-step explanation:

3 hours x 550 (per hour) = 1650

1/2 of 550 or 30 minutes = 275

275 x 0.5 (30 minutes) = 1375

1650 + 1375 = 3225 miles in 3.5 hours

Can someone help me please?
Masja [62]

Given:

A line segment AB.

A point is \dfrac{3}{10} of the way from A to B.

To find:

The coordinates of that point.

Solution:

Section formula: If a point divide a line segment in m:n, then

Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)

From the given figure, it is clear that the two end points of the line segment are A(-4,-5) and B(12,4).

Let the unknown point be P. The point is \dfrac{3}{10} of the way from A to B. It means,

\dfrac{AP}{AB}=\dfrac{3}{10}

Let AP and AB are 3x and 10x, then

\dfrac{AP}{PB}=\dfrac{AP}{AB-AP}

\dfrac{AP}{PB}=\dfrac{3x}{10x-3x}

\dfrac{AP}{PB}=\dfrac{3x}{7x}

\dfrac{AP}{PB}=\dfrac{3}{7}

It means, point P divided the line segment in 3:7.

Using section formula, we get

P=\left(\dfrac{3(12)+7(-4)}{3+7},\dfrac{3(4)+7(-5)}{3+7}\right)

P=\left(\dfrac{36-28}{10},\dfrac{12-35}{10}\right)

P=\left(\dfrac{8}{10},\dfrac{-23}{10}\right)

P=\left(0.8,-2.3\right)

Therefore, the coordinates of the required point are (0.8, -2.3).

The area of a triangle is 40 square inches. its base is 20 inches. find the altitude
Nadya [2.5K]

Answer: The altitude is 4

Step-by-step explanation:

Once you know the area, you have to work backwards. I flipped the area equation to solve for height and got 2A/b = h. After that I plugged in the numbers and got an altitude of 4.

Emma and Max want to buy a house together.
Alex

Answer:

  £123,000

Step-by-step explanation:

Their combined income is ...

  £18,500 +22,500 = £41,000

They can borrow 3 times this amount, or ...

  3 × £41,000 = £123,000

__

<em>Comment on this transaction</em>

The required deposit is 5% of 130,000 = 6,500, which is more than their savings. After this down payment is made, the remaining value is £123,500, which exceeds their borrowing power. It appears that Emma and Max need to find a house with a lower price.
