Seorang penjual beras mencampur 3 jenis beras. campuran pertama terdiri atas 1 kg jenis a , 2 kg jenis b , dan 4 kg jenis c diju

Translation to English:

A rice supplier mixes three different types of rice into three different blends; Type A, Type B, and Type C.

He blends 1 kg of type A, 2 kg of type B, and 4 kg of type C and sells the blend for IDR 19500
He also blends 2 kg of type A and 3 kg of type B and sells the blend for IDR 19000
The third blend consists of 1 kg of type B and 1 kg of type C and this blend is sold for IDR 6250

Which type of rice is the most expensive?

Solution:

Start with the third blend:
1 kg of type B + 1 kg of type C = 6250
B + C = 6250
B = 6250 - C

Then move on to the second blend:
2 kg of type A + 3 kg of type B = 19000
2A + 3B = 19000
2A + 3(6250 - C) = 19000
2A + 18750 - 3C = 19000
2A - 3C = 19000 - 18750
2A - 3C = 250
2A = 250 + 3C
A = [250 + 3C] / 2

Then move on to the first blend:
1 kg of type A + 2 kg of type B + 4 kg of type C = 19500
A + 2B + 4C = 19500
$\frac{250+3C}{2}+2(6250-C)+4C=19500$ ⇒ Multiply each term by 2
$(250+3C)+4(6250-C)+8C=39000$
$250+3C+25000-4C+8C=39000$
$25250+7C=39000$
$7C=39000-25250$
$7C = 13750$
$C=1964.3$

B + C = 6250
B + 1964.3 = 6250
B = 6250 - 1964.3
B = 4285.7

A = [250+C] /2
A = [250 + 1964.3] / 2
A = 1107.15

The most expensive rice is type B

For each equation, tell whether or not it defines a linear function, and explain how you know.

alekssr [168]

A linear function is usually in the form: y=Mx+c. In equation 1, there is no x term and same for equation 3, leaving your only and correct answer to be equation 2. And if you rearrange equation 2, you will get: 5y = -2x + 8.

What is the measure of 2 if 1 is (4x - 4) and 2 is (4x)?

Nutka1998 [239]

The measure of <2 is 92 degrees

<h3>How to solve for 2?</h3>

The complete question is in the attached image

The angles are given as:

<1 = 4x - 4

<2 = 4x

The sum of angles on a straight line is

<1 + <2 = 180

So, we have:

4x - 4 + 4x = 180

Evaluate the like terms

8x = 184

Divide by 8

x = 23

Substitute x = 23 in <2 = 4x

<2 = 4 * 23

Evaluate

<2 = 92

Hence, the measure of <2 is 92 degrees

In the plane figure, only downward motion (movement leaving you relatively lower than where you were) is allowed. Find the total

bixtya [17]

Plane figures are shapes with straight sides. Considering the movement to be lower than the initial path, there are eleven (11) paths from A to B.

A plane figure is given shape with straight sides. And these sides connect each edge of the figure one to another. Examples are triangles, quadrilaterals, polygons, etc.

A path is a connection or link between two reference points. This could be a footpath or a motorable path or other forms of the path.

Considering the given plane figure in the question, it can be observed that the total number of paths from A to B with respect to the given condition is eleven.
