Convert 3/8 to a decimal and percent but pls explain how you guys get 375 pls ;-;
natali 33 [55]
You just divide 3 by 8. when 3 is inside the "house" and 8 is outside, 8 doesn't go into 3 so move on and 8 goes into 30 3 times. and so forth. 30-24=6 bring down the 0. 8 goes into 60 7 times. the decimal is 0.375. the percent is 37.5%.

At the candy shop, Ameenah sells chocolate covered raisins, c, for $1.50 per pound, and peanuts, p, for $1.20 per pound. Ameenah
insens350 [35]

Answer:

10 pounds of raisins and 10 pounds of peanuts.

Step-by-step explanation:

Let c represent the pounds of chocolate covered raisins.

Let p represent the pounds of peanuts.

We know that the raisins cost $1.50 per pound and the peanuts cost $1.20 per pound.

Ameenah wants to make 20 pounds of a mixture of the raisins and peanuts that sells for 1.35 a pound. So, we can write the following expression:

1.5c+1.2p

This represents the cost given c pounds of raisins and p pounds of peanuts.

Ameenah wants to combine c and p to make them 1.35 per pound. In other words, the expression must equal:

1.5c+1.2p=1.35(c+p)

We also know that she wants to make 20 pounds. So, c plus p must total 20. Therefore:

c+p=20

We now have the system of equations:

\left\{ \begin{array}{ll} 1.5c+1.2p=1.35(c+p) \\ c+p=20\end{array}

First, since we know that c+p is 20, we can substitute that into the first equation.

Second, let's subtract p from both side for the second equation to isolate a variable. So:

c=20-p

Let's now substitute this into the first equation:

1.5(20-p)+1.2p=1.35(20)

Distribute:

30-1.5p+1.2p=27

Combine like terms:

-0.3p+30=27

Subtract 30 from both sides:

-0.3p=-3

Divide both sides by -0.3. So, the amount of peanuts needed is:

p=10

10 pounds of peanuts is needed.

This means that 20-10 or 10 pounds of raisins is needed.

A tower that is 111 feet tall casts a shadow 126 feet long. find the angle of elevation of the sun to the nearest degrre
Sergeeva-Olga [200]
The angle here is an acute angle at ground level.  Then the side adjacent to this angle is 126 feet.  The opp. side is the tower, 111 feet tall.

Then   

tan theta = opp / adj = 111 / 126.  Using the inverse tangent function, we find that the measure of the angle is 0.722 radian or 41 degrees (to the nearest degree).
