Pepsi [2]

Answer:

m = 8/5 or 1 3/5

Step-by-step explanation:

8 - 3m = 2m

add 3m to each side

8 - 3m+ 3m = 2m+ 3m

8 = 5m

divide by 5 on each side

8/5 = 5m/5

8/5 = m

Elsa is selling bracelets at craft shows to raise money for an animal shelter.

JulijaS [17]

Answer:

$258

Step-by-step explanation:

75% = 0.75 when we divide by 100 to convert a percentage to a decimal

75% of total sales = money donated

Total sales = sales from first show + sales from second show

= 24n+32 + (40n+56)

= 64n + 88

0.75 of (64n+88) = money donated

= 0.75 * (64n+88)

= 48n + 66

substitute 4 for n, as she charges $4 for each bracelet

money donated = 48*4 + 66 = 258

This is my next Trigonometry question I am needed help on- I just want to be sure I've got it right, or if not, then the steps I

Reptile [31]

$\bf cos(\theta)=\cfrac{3}{5}\cfrac{\leftarrow adjacent=a}{\leftarrow hypotenuse=c}
\\\\\\
c^2=a^2+b^2\implies \pm\sqrt{c^2-a^2}=b\implies \pm\sqrt{5^2-3^2}=b
\\\\\\
\pm\sqrt{16}=b\implies \pm4=b$

so, plus or minus? well, the angle is in the 1st quadrant, and on that quadrant, both cosine and sine are positive, so 4 = b

$\bf tan(\theta)=\cfrac{opposite}{adjacent}\implies tan(\theta)=\cfrac{4}{3}$

You are a NASCAR fan that collects cars that are 1:64 scale to the original car. If your collection has cars that are 3 inches i

Fudgin [204]

Since we know that the ratio of the model car to the real car is 1:64, therefore we use this to solve this true length of the real NASCAR vehicle, let us call this us X, so that:

1 : 64 = 3 inches : X

1 / 64 = 3 inches / X

X = 192 inches

<span>
The true length is 192 inches</span>
