Answer:

I'll setup the problem, then you can do the calculations

Step-by-step explanation:

Perimeter = 2width(W) + 2length (L)

Area = LW

L = 2.5 + 2W

LW = 62.5

substitute L in equation for area

2.5W +  {2W}^{2}  = 62.5 \\  \\  {2W}^{2}  + 2.5 - 62.5 \\  \\  use \:  quadratic \:  solution \\\frac{ - b ±  \sqrt{ {b}^{2}  - 4ac}}{2a}

a = 2; b = 2.5; c = 62.5

carl invests $10000,partly in a secure GIC at 5% and the rest in a mutual fund that he thinks will earn 7.5%. if he expects to e
Oduvanchick [21]
Let the amount he invested in the 5% rate be x and the one in the 7.5% rate be y, then
x + y = 10000 . . . (1)
0.05x = 0.075y . . . (2)

From (2), x = 0.075y/0.05 = 1.5y . . . (3)

Putting (3) into (1) gives
1.5y + y = 10000
2.5y = 10000
y = 10000/2.5 = 4000
x = 1.5(4000) = 6000

Therefore, he invested $6,000 in the secure GIC at 5% and $4,000 in the mutual fund.

Find the value of y and z
elena55 [62]

\qquad\qquad\huge\underline{{\sf Answer}} \huge♨

In the given figure, NQ acts as a diameter and since diameter subtends 90° at the arc of the circle, so we can conclude that ~

\qquad \sf  \dashrightarrow \:3y = 90 \degree

\qquad \sf  \dashrightarrow \:y = 90 \degree \div 3

\qquad \sf  \dashrightarrow \:y = 30 \degree

Now, Let's use Angle sum property of Triangle to solve for z :

\qquad \sf  \dashrightarrow \:4z + 3y + 50 \degree = 180 \degree

\qquad \sf  \dashrightarrow \:4z +90 \degree + 50 \degree = 180 \degree

\qquad \sf  \dashrightarrow \:4z  = 180 \degree  -  (50 \degree  + 90\degree)

\qquad \sf  \dashrightarrow \:4z  = 180 \degree  -  (140\degree)

\qquad \sf  \dashrightarrow \:4z = 40 \degree

\qquad \sf  \dashrightarrow \:z = 40 \degree \div 4

\qquad \sf  \dashrightarrow \:z = 10 \degree

I hope you understood the procedure, you can ask me in comments if you have any doubts.
