Answer: 0.47

Step-by-step explanation:

0.47% = 0.0047 in decimal form. Percent means 'per 57'. So, 67Inches means 0.47 per 100 or simply 0.47/100. If you divide 0.47 by 100, you'll get 0.0047 (a decimal number).

Answer:

8/9, 8/10, 8/11, 8/12

Step-by-step explanation:

If you convert the fractions to percents, 8/9 would be 88%, 8/10 would be 80%, 8/11 would be 72%, and 8/12 would be 66%. Since its greatest to least, you would use the original fractions, but these percents would help you get the correct answer.

Answer: To make 4 pancakes, Simon will need 125 ml milk, 70 grams flour, and 2.5 grams of butter.

Step-by-step explanation:

If that is the recipe to make 8 pancakes, and Simon has 4 pancakes, then Simon needs to cut the recipe in half. So we can multiply each ingredient by 1/2.

250 x 1/2 = 125.

140 x 1/2 = 70.

5 x 1/2 = 2.5

In conclusion, to make 4 pancakes, Simon will need 125 ml milk, 70 grams of flour, and 2.5 grams of butter.

Answer:

D: 12.51 is the correct answer

Answer:

[tex]V=12.5\,\,in^3[/tex]  (answer D)

Step-by-step explanation:

Recall that the volume (V) of a sphere in temrs of its radius (R) is given by the formula:

[tex]V=\frac{4}{3} \pi R^3[/tex]

Therefore, in our case we have:

[tex]V=\frac{4}{3} \pi 1.44^3=12.5\,\,in^3[/tex]

Answer:

The presents age of the mom is 42 years old, and of the son is 27 years old.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

The mothers age is x.

The son's age is y.

12 years ago, a mother was twice as old as her son.

This means that:

[tex]x - 12 = 2(y - 12)[/tex]

[tex]x = 2y - 24 + 12[/tex]

[tex]x = 2y - 12[/tex]

Their present age are in the ratio of 14:9.

This means that:

[tex]\frac{x}{y} = \frac{14}{9}[/tex]

[tex]14y = 9x[/tex]

Since [tex]x = 2y - 12[/tex]

[tex]14y = 9(2y - 12)[/tex]

[tex]18y - 108 = 14y[/tex]

[tex]4y = 108[/tex]

[tex]y = \frac{108}{4}[/tex]

[tex]y = 27[/tex]

[tex]x = 2*27 - 12 = 54 - 12 = 42[/tex]

The presents age of the mom is 42 years old, and of the son is 27 years old.

Answer:

1/6x= 65

Step-by-step explanation:

so we can assume that 5/10= 1/6 of the deer were tagged

lets call the total number of dear x

so 1/6x= 65

x= 380

The proportion that can be used to estimate the number of deer in the forest is 5/30 = 65/390

To estimate the number of deer in the forest, we can set up a proportion using the tagged deer in the sample as a representative of the entire population.

Let's denote the number of deer in the forest as 'x'.

We know that 65 deer were tagged out of the total population. In the sample of 30 deer, 5 were tagged.

Therefore, we can set up the following proportion:

Tagged deer in sample / Total deer in sample = Tagged deer in population / Total deer in population

5 / 30 = 65 / x

Now we can cross-multiply to solve for x:

5x = 65 * 30

5x = 1950

Dividing both sides by 5:

x = 1950 / 5

x = 390

Therefore, the proportion that can be used to estimate the number of deer in the forest is 5/30 = 65/390
