Answer:

m= 1.1

Step-by-step explanation:

Given the question as 7:( 4/11 m)=56:3.2 this can be written as;

7: 4/11 m = 56 /3.2

7/4/11m = 560/32 ------------------perform cross multiplication

77*32=560*4/11m

224=2240/11 m

224=203.636 m--------------divide both sides by 203.636 to get m

224/203.636 = 203.636m/203.636

1.1 =m

Testing the value of m in the question

7: (4/11 *1.1) = 56:3.2

7:0.4 = 56 :3.2

70/4 = 560/32

17.5 =17.5

Helps me solve this problem please

Answer:

The slope is -3/7 so B

Step-by-step explanation:

Just turn this into slope-intercept form.

what you do is subtract 3x so that it's moved to the right side.

It should look like this -7y = 12 - 3x

Then just divide all numbers by 7 so everything is simplified

It should look like this y = -3/7x - 12/7

pls mark brainliest because i didn't waste you time lol

Select the simplification that accurately explains the following statement.

lutik1710 [3]

Answer:

Option (b) is correct.

$(2^\frac{1}{4} )^4=2^\frac{1}{4} \times 2^\frac{1}{4}\times 2^\frac{1}{4}\times 2^\frac{1}{4}=2^{(\frac{1}{4}+ \frac{1}{4}+ \frac{1}{4}+ \frac{1}{4} )}=2^{1}=2$

Step-by-step explanation:

Given: $(2^\frac{1}{4} )^4$

We have too choose the correct simplification for the given statement.

Consider $(2^\frac{1}{4} )^4$

Using property of exponents, $(a^m)^n=a^m\times a^m\times a^m\times ....\times (n\ times)$

We have,

$(2^\frac{1}{4} )^4=2^\frac{1}{4} \times 2^\frac{1}{4}\times 2^\frac{1}{4}\times 2^\frac{1}{4}$

Again applying property of exponents $a^m\times a^m=a^{n+m}$

We have,

$(2^\frac{1}{4} )^4=2^{(\frac{1}{4}+ \frac{1}{4}+ \frac{1}{4}+ \frac{1}{4} )}$

Simplify, we have,

$(2^\frac{1}{4} )^4=2^{\frac{4}{4}}$

we get,

$(2^\frac{1}{4} )^4=2^{1}=2$

Thus, $(2^\frac{1}{4} )^4=2$

Option (b) is correct.

a laboratory, you determine that the density of a certain solid is 5.23×10−6kg/mm3. Convert this density into kilograms per cubi

Vedmedyk [2.9K]

Answer:

$5.23\times 10^{-6}\ kg/mm^3=5230\ kg/m^3$

Step-by-step explanation:

Given : The density of a certain solid is $5.23\times 10^{-6}$ kg/mm³.

To find : Convert this density into kilograms per cubic meter ?

Solution :

We know that,

$1\ m^3=10^9\ mm^3$

or $10^9\ mm^3=1\ m^3$

So, $1 mm^3=\frac{1}{10^9}\ m^3$

$1 mm^3=10^{-9}\ m^3$

Converting $5.23\times 10^{-6}$ kg/mm³ into kg/m³,

$5.23\times 10^{-6}\ kg/mm^3=\frac{5.23\times 10^{-6}}{10^{-9}}\ kg/m^3$

$5.23\times 10^{-6}\ kg/mm^3=5.23\times 10^{-6+9}\ kg/m^3$

$5.23\times 10^{-6}\ kg/mm^3=5.23\times 10^{3}\ kg/m^3$

$5.23\times 10^{-6}\ kg/mm^3=5230\ kg/m^3$

Therefore, $5.23\times 10^{-6}\ kg/mm^3=5230\ kg/m^3$

How do i make 1\2x-y=4 into slope intercept form

kari74 [83]

Simple, since you want to find y, in y=mx+b form, move everything to the other side.

1/2x-y=4

Move 1/2x

1/2x-y=4
-1/2x -1/2x

Making it look like,

-y=4-1/2x

Divide by the negative 1 in front of the y,

-y=4-1/2x
/-1 /-1

y=-4+1/2x

or

y=1/2x-4

Thus, this written in y=mx+b form, y=1/2x-4.
