An ant crawls at a rate of 216 ft per minute.

AysviL [449]

First, we need to understand the speed formula:

The time used = distance ÷ rate

In this case, the time needed would be:

5 1/5 ÷ 2 1/6
= (5×5+1)/5 ÷ (2×6+1)/6
=26/5 ÷ 13/6

When there is division in an equaiton, we can swap the nominator and denominator of the fraction amd change it to multiplication:

=26/5 × 6/13
= (13 x 2)/5 x 6/(13 x 1)

Factorize 26 and 13,we get:

=2/5 x 6/1
= 12/5 ft or 2.4 ft

Therefore the answer is 12/5ft or 2.4ft.

Hope it helps!

In the right triangle shown in the diagram below,

adelina 88 [10]

QUESTION :-

what is the value of x to the nearest whole number?

ANSWER :-

$\cos( \theta) = \frac{base}{hypotenuse} \\ \cos(30) = \frac{x}{24} \\ \frac{ \sqrt{3} }{ \cancel2} = \frac{x}{ \cancel{24}} = \frac{x}{12} \\ 1.732 = \frac{x}{12} \\ 12 \times 1.732 = x \\ x = 20.7$

the nearest whole number-->

20.7 --> approximately --> 21 units

Step-by-step explanation:

Prime factorization of 48 is :

$48=2\times 2 \times 2 \times 2 \times 3\\\\=2^4\times 3^1$

Option (3) is true.

Prime factorization of 19 is:

19 = 19 × 1

Option (c) is correct.

(10).

Prime factorization of 924 is:

924 = 2 x 2 x 3 x 7 x 11

= 2² x 3¹ x 7¹ x 11¹

Hence, this is the required solution.
