Of the 30 students in the sixth period math class, 8 are also in the same fourth period science class. Which can be used to dete

Kazeer [188]

Answer:

A. (8/30)(22/29)(21/28)

Step-by-step explanation:

The key is in reading the question really thoroughly, like, way more than you would expect. The <em>first</em> person is from the group of 8, thus (8/30), but the other <em>two</em> <u>cannot</u> be from the group of 8. 30(students total) minus 8 (the 8 people from science class)=22 (remaining in math). You choose one person who is <em>not</em> from the group of 8, and you are left with 21 other people. The number of students available to be in a group goes down each time: 30 down to 29 down to 28 (the denominators). Kaboom, A. (8/30)(22/29)(21/28).

There are bricks of silver and bricks of gold. When 5 silver bricks and 2 gold bricks are placed on a scale, the weight is 119 o

Illusion [34]

Answer:

The weight of one gold brick is 15 ounces and the weight of one silver brick is 22 ounces.

Step-by-step explanation:

Given,

Weight of 5 silver bricks and 2 gold bricks = 119 ounces.

And Weight of 4 silver bricks and 11 gold bricks = 302 ounces.

We have to find out weight of each type of brick.

Solution,

Let the weight of 1 silver brick be x.

And the weight of 1 gold brick be y.

Since the weight of 5 silver bricks and 2 gold bricks is 119 ounces.

So we can frame it in equation as;

$5x+2y=119\ \ \ \ \ equation\ 1$

Again,

The weight of 4 silver bricks and 11 gold bricks is 302 ounces.

So we can frame it in equation as;

$4x+11y=302\ \ \ \ \ equation\ 2$

Now, multiplying equation 1 by 4 and equation 2 by 5 we get;

$4(5x+2y)=119\times4\\\\20x+8y=476\ \ \ \ \ equation\ 3$

$5(4x+11y)=302\times5\\\\20x+55y=1510\ \ \ equation\ 4$

Now subtract equation 3 from equation 4, we get;

$(20x+55y)-(20x+8y)=1510-476\\\\20x+55y-20x-8y=1034\\\\47y=1034\\\\y=\frac{1034}{47}\\\\y=22$

On substituting yhe value of y in equation 1, we get;

$5x+2y=119\\\\5x+2\times22=119\\\\5x+44=119\\\\5x=119-44=75\\\\x=\frac{75}{5}\\\\x=15$

Thus the weight of one gold brick is 15 ounces and the weight of one silver brick is 22 ounces.
