Are you doing equivalent fractions? If so, they're not. If you want to see which one is bigger, here is what you do. Since 63 is bigger than 16, 7/4 would be bigger.

The twenty-six coins in my pocket are all dollar coins and quarters, and they add up to seventeen dollars in value. How many dol

Law Incorporation [45]

Currency such as dollars can come in various forms such as dimes, quarters, pennies, and nickels.

The number of quarter coins is 12 and the number of dollar coins is 14 coins.

Let's represent:

The number of 1 dollar coin = d

The number of 1 quarter coin = q

The twenty-six coins in my pocket are all dollar coins and quarters. The algebraic equation for this statement above is =

d + q = 26 ........ Equation 1

Making d the subject of the formula

d = 26 - q

1 dollar coin = $1

1 quarter = $0.25

The value of the dollar and nickel coins is seventeen dollars. The algebraic expression for this statement is :

$1 x d + $0.25 x q = 17

d + 0.25q = 17.................Equation 2

Substitute 26 - q for d in Equation 2

26 - q + 0.25q = 17

Collecting like terms

26 - 17 = q - 0.25q

9 = 0.75q

Divide both sides by 0.75

9/0.75 = 0.75q/0.75

q = 12 coins

Solving for number of dollar coins

d = 26 - q

q = 12

d = 26 - 12

d = 14 coins

Therefore, the number of quarter coins is 12 and the number of dollar coins is 14 coins.

Find the length of DE. Round to the nearest hundredth. (Picture included)

LenKa [72]

Notice the picture
we have, the opposite side
the angle
and we want the hypotenuse

so recall your SOH CAH TOA $\bf sin(\theta)=\cfrac{opposite}{hypotenuse}
\qquad \qquad 
% cosine
cos(\theta)=\cfrac{adjacent}{hypotenuse}

\\ \quad \\\\
% tangent
tan(\theta)=\cfrac{opposite}{adjacent} =$

which one has all that? low and behold, is Ms Sine,
so let's bother Ms Sine

$\bf sin(\theta)=\cfrac{opposite}{hypotenuse}\implies sin(27^o)=\cfrac{18}{hypotenuse}
\\\\\\
hypotenuse=\cfrac{18}{sin(27^o)}$

make sure your calculator is in Degree mode, since the angle here is in degrees, as opposed to Radian mode
