Divide 310AED among A B C in the ratio 2:3:5

Shkiper50 [21]

Answer:A=62AED B=93 C=155

Step-by-step explanation:

You add all of the numbers to split between (2,3,5) you get 10

then you divided 310 by 10 which is 31

then you times 2 by 31=62 (a)

3x31=93 (b)

Adam is planning a party for his daughter, Rachel. The party has a beach theme. Adam plans to fill a sandbox with fresh sand so

babunello [35]

Answer:

Volume = 144 ft

Step-by-step explanation:

1. Let's write some things down, so we don't forget them!

Length = 12 ft

Height = 2 ft

Width = 6 ft

2. We can probably assume the sandbox is a rectangle. The formula for the volume of a rectangle is Length x Height x Width. So, 12 x 2 x 6 = 144, therefore that's the volume!

Find the median 60,62,64,54,56,28

Arada [10]

Answer:

Step-by-step explanation:

you need to order all the numbers together:

28, 54, 56, 60, 62, 64

since the middle 2 are 56 and 60 you need to find the average of those.

(56 + 60)/2 = 58

19. For the following exercises, use the descriptions of each pair of lines given below to find the slopes of Line 1 and Line 2.

worty [1.4K]

Answer:

The given lines are un-related.

Step-by-step explanation:

In the question, two lines are given as line 1 passes through (-8,-55) and (10,89). Whereas, line 2 passes through (9,-44) and (4,-14).

It is required to find the slope of given lines and figure out whether they are perpendicular, parallel or neither.

To solve this question, first find the slope of both lines. Check if their product is equal to -1, then they are perpendicular. If the slopes are equal the lines are parallel.

Step 1 of 2

Find the slope of first line.

$\begin{aligned}&m_{1}=\frac{89-(-55)}{10-(-8)} \\&m_{1}=\frac{144}{18} \\&m_{1}=8\end{aligned}$

Step 2 of 2

Find the slope of first line.

$\begin{aligned}&m_{2}=\frac{-14-(-44)}{4-9} \\&m_{2}=\frac{30}{-5} \\&m_{2}=-6\end{aligned}$

Since, both slopes are neither equal nor reciprocal of each other.

Therefore, the lines are un-related.
