Answer:

$slope (m) = -\frac{3}{4}$

Step-by-step explanation:

Slope of the line using two pairs of values from the table, (-2, 5) and (2, 2):

$slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{2 - 5}{2 - (-2)} = \frac{-3}{4}$

$slope (m) = -\frac{3}{4}$

4/5z=16 solve equation (that's a fraction )

Assoli18 [71]

So we need to isolate the variable. In order to do that, we need to multiply both sides by 5/4.
Why? That's so that 4/5z will be canceled out when multiplied by 5/4 to get just z.
And so, we would get 20 as our answer.

Rename 7/20 as a percent

igomit [66]

Step-by-Step Explanation:

a) Rename $\frac{7}{20}$ as a percent

$\frac{7}{20}\times 100\\\\=7\times 5\\\\=35\%$

b) Rename .245 as a percent

$.245\times 100\\\\=\frac{245}{1000}\times 100\\\\=24.5\%$

c) Rename 28% as a fraction and a decimal in simplest form

$28\%=\frac{28}{100}=\frac{7}{4}\text{ as a fraction}\\\\\frac{7}{4}=1.75\text{ as a decimal}$

d) Put .367,36.5%, $\frac{9}{25}$ in order least to greatest.

$\text{ First we put change all into percent form}\\\\.367\times 100=\frac{367}{1000}\times 100=36.7\%\\\\\frac{9}{25}\times 100=9\times 4=36\%$

Now, we have 36.7%, 36.5%, 36%

We have write it in ascending order i.e. least to greatest ,

Here it is,

36%, 36.5%, 36.7%

$\frac{9}{25},36.5\%\ and\ .367$

I need help with a math question

Julli [10]

Answer:

Question 1: 4.5(10^−7)(2(10^4))

=

9/1000

(Decimal: 0.009)

Question 2:

mass of neutron/mass of electron = 2*10-24/(9*10-28)

2x10^(-24)/9x10^(-28)

d is closest.

Question 3:

4(10^3)(12(10^5))

=4000*1200000

=4*1000*12*100000

=(4*12)*(1000*100000)

=48*100000000

=4800000000

And these things : ^ mean raising the number to become exponets and when I put the number into a bold text thats the answer!

<em>Hope</em><em> </em><em>this</em><em> </em><em>helps</em><em>!</em><em> </em><em>if</em><em> </em><em>so</em><em> </em><em>pls</em><em> </em><em>mark</em><em> </em><em>brainliest</em><em> </em><em>and</em><em> </em><em>heart</em><em>/</em><em>rate</em><em>!</em>
