Answer:

m = 0.5

Step-by-step explanation:

Step 1 : Take the cube root of it.

Basically what this means is that you multiply the reciprocal of it to the 0.125

Like this:

m^3 = 0.125 ---------> m = 0.125 (1/3)

Step 2: Solve

m = 0.125 (1/3)

m = 0.5

I hope this helps!

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

olya-2409 [2.1K]

Answer:

She will be able to make 8 wreaths

Step-by-step explanation:

I got my answer by first converting 3 1/4 into 13/4. I then divide 28 by 13/4 which was multiplying 28 by 4/13.

I got 112 when I did 28 × 4

I then divided 112 by 13

and got 8.615.

Since they are asking for how much wreaths she could make, it is going to be 8
