4x+8y= 16
Possible combinations are;
(x, y)
(0, 2) 4(0)+8(2)=16
(1, 1.5) 4(1)+8(1.5)=16
(2, 1). 4(2)+8(1)=16
(3, 0.5) 4(3)+8(0.5)=16
(4, 0) 4(4)+8(0)=16
I hope this helps you out.

A triangle has side lengths of 21, 27, and 35 inches. Is it right triangle?

DIA [1.3K]

Answer: No
In right triangle we have 30:60:90
and the ratios are
x: x root of 3: 2x
so, for example, if we have side of length 3 against 30 degrees, then against 60 degrees the side will be 3 root of 3, and against 90 degrees it will be 6.
Hope it helps!

Find the surface area of a cylinder with a height of 8 ft and a base radius of 5 ft.

Maksim231197 [3]

Answer: 408.2 ft^2

Step-by-step explanation:

A=2πrh+2πr2

A=2(3.14)(5)(8)+2(3.14)(5)^2

A=6.28*40+6.28*25
A=251.2+157

A=408.2 ft^2

How do the lengths of line segments define the golden ratio?

NISA [10]

Answer:

$\frac{a+b}{a}=\frac{a}{b}$

Step-by-step explanation:

The golden ratio is a special number favored by the Greeks. Its ratio roughly equals 1.618. The ratio is formed by taking a line segment and dividing it into two parts labeled a and b. The golden ratio is formed when this proportion is true $\frac{a+b}{a}=\frac{a}{b}$ .

When you add a and b then divide by a, it will be the same as a divided by b. This will hold true only for specific lengths of a and b. This means you must divide the line segment in such a way that a and b meet this requirement.

Example:

If the line segment is 50 cm long. Split the segment into parts a and b where a = 30.9 and b = 19.1. Substitute the values into the proportion $\frac{a+b}{a}=\frac{a}{b}$ .

$\frac{30.9+19.1}{30.9}=\frac{30.9}{19.1}$

$\frac{50}{30.9}=\frac{30.9}{19.1}$

1.618 = 1.618

This is the golden ratio.

An amount of $21,000 is borrowed for 10 years at 3.25% interest, compounded annually. If the loan is paid in full at the end of

Yanka [14]

The formula for total loan cost is attached.
10 years = 120 payments
MONTHLY Interest = .0325 / 12 = 0.0027083333 

total = 0.0027083333 * 21,000 * 120 / (1-(1.0027083333)-120 
total = 6,825 / (1- 0.7228448406 )
total = 6,825 / 0.2771551594 
total = 24,625.20
