What is the multiplier for 5/7=30/42 please help

Mathematics
1 answer:
horsena [70]3 years ago
8 0

Answer:

The multiplier is 1

specifically:

\frac{6}{6}

Step-by-step explanation:

Let the multiplier be k

Then,

\frac{5}{7}  \times k =  \frac{30}{42}

We multiply both sides by 7/5

\frac{7}{5}  \times  \frac{5}{7} k =  \frac{30}{42}  \times  \frac{7}{5}

k =  \frac{6}{6}

We can simplify this further to get 1.

This implies that:

\frac{5}{7}  \times  \frac{6}{6} =  \frac{30}{42}

Hence the multiplier is 1.

Given a system of linear equations: dy/dx = 4x-y dy/dx = x-2y Find the general solution.
mina [271]

Answer:

x=-y/3

y=-3x

Step-by-step explanation:

dy/dx=4x-y means 4x-y=0

dy/dx=x-2y also means x-2y=0 then

4x-y=x-2y

3x=-y

y=-3x

x=-y/3

Find the variance and standard deviation of 5,6,7,8,9
34kurt

Step-by-step explanation:

To figure out the variance, subtract 82.5 from the mean, which is 5.5 and then divide by N, which is the value of numbers, (in this case 10) minus 1. The result is a variance of about 9.17. Standard deviation is the square root of the variance so that the standard deviation would be about 3.03.Calculate the mean.

Subtract the mean from each observation.

Square each of the resulting observations.

Add these squared results together.

Divide this total by the number of observations (variance, S2).

Use the positive square root (standard deviation, S).

The length of a rectangular fenced enclosure is 12 feet more than the width. If Farmer Dan has 100 feet of fencing, write an ine
Kitty [74]
Answer:
length = 31 ft
width = 19 ft

Explanation:
Assume that the width of the rectangle is w.
We are given that the length is 12 ft more than the width. This means that the length of the rectangle is w + 12

The perimeter of the rectangle in this case would be:
perimeter = 2 (length + width)
perimeter = 2 (12 + w + w)
perimeter = 24 + 4w

Assume that Dan would use all 100 ft of fencing to surround the yard. This would mean that the largest perimeter is 100 ft.

Therefore:
perimeter = 24 + 4w
100 = 24 + 4w
4w = 100 - 24
4w = 76
w = 19 ft

Since we have calculated that the width of the yard is 19 ft, we can substitute to get the length as follows:
length = 12 + w
length = 12 + 19
length = 31 ft

Hope this helps :)
