Solve for y: x/y - 8 = w

inysia [295]

X/y-8=w
x-8y=wy
x=wy+8y
x=y(w+8)
y= $\frac{x}{w+8}$

A college student completed some courses worth 3 credits and some

-BARSIC- [3]

Answer:

A. 13

Step-by-step explanation:

Note: It seems typo in the question. 5% should read 59.

Let 3 credit courses = x, 4 credit courses = y

As per given we have following equations:

x + y = 18
3x + 4y = 59

Solve the system by elimination. Multiply the first equation by 4 and subtract the second one:

4(x + y) - (3x + 4y) = 4(18) - 59
4x + 4y - 3x - 4y = 72 - 59
x = 13

The answer is 13

Correct choice is A

A cuboid has side lengths 3cm, 4cm and 7cm. A cylinder with a height double that of the longest side of the cuboid has the same

mart [117]

Step-by-step explanation:

Longest side of cuboid: 7cm

Height of cylinder:

2 × 7 = 14 cm

Volume of cuboid:

7x3x4=84 $cm^3$

Volume of cylinder:

$84=14\pi r^2 \\r=\sqrt{\frac{6}{\pi} } \ \ \ cm\\r=1.38 \ cm\\$

Surface area of the cylinder:

$\pi r^2 + 2 \pi r h$

$6+2\pi (\sqrt{\frac{6}{\pi} } ) (14)$

=128 cm^2
