Because 10 cups are used to make 5 batches, you would need 2 cups to make 1 batch. To find this, I divided 10/5 to get 2. So, for 5 batches, you would do 2 x 5 to get 10 cups.

Hope this helps!

So you have 10 total cups and 5 batches. Assuming that the raisens are evenly distributed, you get 10/5, which is 2 raisin cups per batch

180 lb 12 oz - 79.3 kg = ___________ kg
Brrunno [24]

Answer:

180lb\ 12 oz - 79.3kg = 2.8kg

Step-by-step explanation:

Given

180\ lb 12\ oz - 79.3kg

Required

Solve

First, convert 180lb to kg

1lb \to 0.454kg

180lb \to 180 *0.454kg

180lb \to 81.7kg -- to 1dp

Next, convert 12oz to kg

1oz \to 0.03kg

12oz \to 12 * 0.03kg

12oz \to 0.4kg --- to 1 dp

So, the expression becomes:

180\ lb 12\ oz - 79.3kg

81.7kg + 0.4kg - 79.3kg

= 2.8kg

Hence:

180lb\ 12 oz - 79.3kg = 2.8kg

If BC = 5 and CD = 26, find AC.
Blababa [14]

Answer:

AC=\sqrt{130}

Step-by-step explanation:

AC is the geometric mean.  Solve it using this proportion:

\frac{BC}{AC}=\frac{AC}{CD}

Now fill in the values we know:

\frac{5}{AC}=\frac{AC}{26}

Cross multiply to get

(AC)^2=130

That means that

AC = \sqrt{130}, which, in decimal form is

AC = 11.40175425

Please someone help me‼️
Flauer [41]

Answer:

6 m

Step-by-step explanation:

The volume of a cone is found by \frac{\pi r^2h}{3}, so we can plug the values in to get 6pi * r^2 / 3 = 72pi, or 6pi * r^2 = 216 pi, so r^2 = 36 and the radius is 6 m.

A bag contain 3 black balls and 2 white balls.
Troyanec [42]

Answer:

Step-by-step explanation:

Total number of balls = 3 + 2 = 5

1)

a)

Probability \ of \ taking \ 2 \ black \ ball \ with \ replacement\\\\ = \frac{3C_1}{5C_1} \times \frac{3C_1}{5C_1} =\frac{3}{5} \times \frac{3}{5} = \frac{9}{25}\\\\

b)

Probability \ of \ one \ black \ and \ one\ white \ with \ replacement \\\\= \frac{3C_1}{5C_1} \times \frac{2C_1}{5C_1} = \frac{3}{5} \times \frac{2}{5} = \frac{6}{25}

c)

Probability of at least one black( means BB or BW or WB)

 =\frac{3}{5} \times \frac{3}{5} + \frac{3}{5} \times \frac{2}{5} + \frac{2}{5} \times \frac{3}{5} \\\\= \frac{9}{25} + \frac{6}{25} + \frac{6}{25}\\\\= \frac{21}{25}

d)

Probability of at most one black ( means WW or WB or BW)

=\frac{2}{5} \times \frac{2}{5} + \frac{3}{5} \times \frac{2}{5} \times \frac{2}{5} + \frac{3}{5}\\\\= \frac{4}{25} + \frac{6}{25} + \frac{6}{25}\\\\=\frac{16}{25}

2)

a) Probability both black without replacement

  =\frac{3}{5} \times \frac{2}{4}\\\\=\frac{6}{20}\\\\=\frac{3}{10}

b) Probability  of one black and one white

 =\frac{3}{5} \times \frac{2}{4}\\\\=\frac{6}{20}\\\\=\frac{3}{10}

c) Probability of at least one black ( BB or BW or WB)

 =\frac{3}{5} \times \frac{2}{4} + \frac{3}{5} \times \frac{2}{4} + \frac{2}{5} \times \frac{3}{4}\\\\=\frac{6}{20} + \frac{6}{20} + \frac{6}{20} \\\\=\frac{18}{20} \\\\=\frac{9}{10}

d) Probability of at most one black ( BW or WW or WB)

 =\frac{3}{5} \times \frac{2}{4} + \frac{2}{5} \times \frac{1}{4} + \frac{2}{5} \times \frac{3}{4}\\\\=\frac{6}{20} + \frac{2}{20} + \frac{6}{20} \\\\=\frac{14}{20}\\\\=\frac{7}{10}
