Karo-lina-s [1.5K]

<h2>~<u>Solution</u> :-</h2>

Here, it is given that the bag contains 25 paise coins and 50 paise coins in which, 25 paise coins are 6 times than that of 50 paise coins. Also, the total money in the bag is Rs. 6.

Hence, we can see that, here, we have been given the linear equation be;

Let the number of coins of 50 paise will be $ x $ and the number of coins of 25 paise will be $ 6x $ as given. . .

Hence,

$x + 6x = 6$

$7x = 6$

$x = \frac{6}{7} \\$

$x = 1.1666667 \approx \: 2$

Hence, the number of 50 paise coins will be <u>2</u>. And, 6 times of two be;

$6(2)$

Hence, the number of 25 paise coins will be <u>12</u>.

Zack and Noah jogged 2/5 of a mile and walked another 1/4 of a mile. How far did they go in all?

Basile [38]

Find a common denominator. The lowest one would come from you multiplying 2/5 by 4 on each side and 1/4 by 5 on each side. You are left with 8/20 and 5/20, added together would be 13/20.

Let ABCDEFGH be a cube and M the midpoint of GH. It is known that the distance between the lines BM and AD is a<img src="https:/

vovikov84 [41]

Answer:

√5

Step-by-step explanation:

We suppose the vertices are named clockwise around the top of the cube, then clockwise around the bottom (looking down from above the cube), with vertex E below vertex D. Then line AD is in plane ADEF, and line BM is in plane BCHG.

The distance between the named parallel planes is the distance between the lines. That distance is AB, which is given as √5.

Write each of the following expressions as a single logarithm.1)log(2)+log(12)2)2log(4)+4log(3)

irga5000 [103]

To solve both questions, we need to use the following two properties of the logarithm function.

$\begin{gathered} \log _b(x\cdot y)=\log _b(x)+\log _b(y) \\ \text{and} \\ \log _b(x^y)=y\log _b(x) \end{gathered}$

In our case,

$\begin{gathered} \log (2)+\log (12)=\log (2\cdot12)=\log (24) \\ \Rightarrow\log (2)+\log (12)=\log (24) \end{gathered}$

The answer to part 1) is log(24).

On the other hand,

$\begin{gathered} 2\log (4)=\log (4^2)=\log (16) \\ 4\log (3)=\log (3^4)=\log (81) \\ \Rightarrow2\log (4)+4\log (3)=\log (16)+\log (81)=\log (16\cdot81)=\log (1296) \\ \Rightarrow2\log (4)+4\log (3)=\log (1296) \end{gathered}$

The answer to part 2) is log(1296)
