provisions for 630 men to last for 25 days. How many men must be transferred to another camp so that the food lasts for 30 days?

algol [13]

Answer:

105

Step-by-step explanation:

25 days = Food for 630 men

30 days = x (Inverse variation)

30 * x = 630 * 25

x = 630 * 25/30

= 21 * 25

= 525 men.

630 - 525 = 105 men.

Therefore, 105 men must be transferred to another camp so that the food lasts for 30 days.

What is the estimated perimeter of an ellipse if the major axis has a length of 15 ft and the minor axis has a length of 7.5 ft?

miskamm [114]

Answer:

Option B is correct.

The estimated perimeter of an ellipse is 37.3ft

Step-by-step explanation:

<u>Given:</u>

Length of Major-axis (2a)=15ft

Length of minor-axis (2b)=7.5ft

For an ellipse, the perimeter (P) approximately given by:

$P\approx 2\pi\sqrt{\frac{a^2+b^2}{2}}$ , where a and b are semi major axis and semi minor axis respectively.(Use approx. value of $\pi =3.1 4$ )

Here, a=7.5ft and b=3.75ft, putting in above equation, we get

$P\approx 2\pi\sqrt{\frac{\left (7.5\right )^2+\left (3.75\right )^2}{2}}$

$P\approx 2\cdot 3.14\cdot \sqrt{\frac{56.25+14.0625}{2}}$

$P\approx\ 6.28\cdot \sqrt{\frac{70.3125}{2}}$

$P\approx\ 6.28\cdot \sqrt{35.15625}$

After solving the square-root we get,

$P\approx\ 6.28\cdot5.92927061$

$P\approx37.3ft$ .

Therefore, the estimated perimeter of an ellipse is 37.3ft.

Mrs. Leonard is planting a flower garden. She has 18 marigolds for every 6 petunias.

tangare [24]

Answer:

B) 1:3

Step-by-step explanation:

Let's layout the information given firstly.

Marigolds= 18

Petunias= 6

In ratios, you need to follow the arrangement, for say in this question they say petunias go first, so the ratio should involve the value 6 first.

Therefore, it will give you, 6:18.

Now, you need to simplify this ratio. Just simplify it as it were, a fraction. Divide each number by a common factor, in this case, it is 6. Once you've done that, you'll get 1:3.

Hope this helped.
