What is the perimeter (in inches) of a television screen that measures 24 1/2 in. by 40 in.?
Bess [88]

The perimeter of the television screen (in inches) is 129 inches.

Given that a television screen in the shape of a rectangle has a length of    40 inches and breadth \frac{49}{2} inches.

Perimeter of rectangle=2(length of rectangle+ bredth of rectangle)

Here the TV screen is the shape of rectangle

Therefore Perimeter of TV screen=perimeter of rectangle

Given the the length of TV screen=40 inches

The bredth of the TV screen= \frac{49}{2} inches.

Perimeter of TV screen=2(40 inches + \frac{49}{2} inches)

Perimeter of TV screen=(80+49) inches

Perimeter of TV screen= 129 inches

Therefore,The perimeter of the television screen (in inches) is 129 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.

PLZZZZ HELP MEEEE!!!! (30 points)
enot [183]

Answer:

Step-by-step explanation:

Slope is the rise (y) over the run (x) between 2 points on a graph. This means that from one point go up (or down) first, then count over from that first point right (or left). A positive number on top indicates "up" and a negative number on top indicates "down"; a positive number on bottom indicates "right" while a negative number on bottom indicates "left". Keep in mind the following:

\frac{-y}{x} =\frac{y}{-x} =-\frac{y}{x}

It doesn't matter where you "put" the negative, your slope will come out correct as long as you are moving from one point to the other correctly.

Our given slope is 4/5. They are both positive, so that means from the red point on the left ("read" a graph from left to right, just like you're reading this) we will go up 4 units. From where we "land" we will go right 5 units. As you can see, the only graph that lands on the red dot on the right when we follow that slope is the second one.
