Change mixed numbers to improper fractions: 9/4 + (-7/5).  Adding a negative is the same as subtraction: 9/4-7/5.  Find a common denominator (20) and change both fractions to have to common denominator 45/20-28/20.  Then subtract numerators = 17/20.  Reduce if possible, which is not in this problem.

Help with translations!
Vadim26 [7]

Given:

The figure of a trapezoid.

The figure is translated down 5 units and then rotated 180 degrees clockwise.

To find:

The coordinates of the image of point W after these transformation.

Solution:

From the given figure it is clear that the coordinates of point W are (-6,3).

The figure is translated down 5 units. So,

(x,y)\to (x,y-5)

W(-6,3)\to W'(-6,3-5)

W(-6,3)\to W'(-6,-2)

After that the figure is rotated 180 degrees clockwise.

(x,y)\to (-x,-y)

W'(-6,-2)\to W''(6,2)

Therefore, the coordinates of point W after the given transformations are (6,2).

Fynjy0 [20]

Answer:

Width = 4 feet

Step-by-step explanation:

Let l = length

Let w = width

l = 3w

l - w = 8

3w - w = 8

2w = 8

w = 4

Suppose given an isosceles triangle with a leg measuring 5 in. Two lines are drawn through some point on the base, each parallel
enot [183]
We have an isosceles triangle  and 2 lines that are drawn through some ( any ) point on the base. The both lines are parallel to one of the legs. Then those lines with the legs of the triangle make a parallelogram. We can say that x and y are the sides of the parallelogram. Then: x + y = 5 in. And the perimeter of the parallelogram: P = 2 x + 2 y = 2 * ( x + y ).
P = 2 * 5 = 10 in.  The rest is in the attachment.
Answer: The perimeter of the constructed parallelogram is 10 inches.

Colin invests £4800 into his bank account.
weeeeeb [17]

Answer:

$5903.39

Step-by-step explanation:

This can be solve using compound interest formula. The formula is:

F=P(1+r)^t

Where

F is the future amount (what we are looking for)

P is the present amount (which is 4800)

r is the rate of compound interest per year, in decimal (3% per year, 3/100 = 0.03)

t is the time in years ( t = 7)

Now we substitute these values into the formula and find F:

F=P(1+r)^t\\F=4800(1+0.03)^7\\F=4800(1.03)^7\\F=5903.39

So, Colin would have $5903.39 after 7 years, in his account.
