1/2 of a bag of candy is skittles, 1/4 is m and m's, and 3/4 of the rest of it are life savers. The rest are sour patch kids. Wh
m_a_m_a [10]

Answer:

6.25%

Step-by-step explanation:

Total = 1 ; as a decimal

1/2 = skittles

1/4 = M&Ms

Skittles +M&Ms = 1/2 + 1/4 = 3/4

Remainder = 1 - \frac{3}{4}

Remainder = \frac{1}{4}

Sour patch = \frac{1}{4} *\frac{1}{4} =\frac{1}{16}

As a percentage , multiply 1/16 by 100 and it becomes 6.25%

Please help me with this homework question. No silly answers please and no bots! I will mark brainliest to whoever gets all them
MatroZZZ [7]

Answer:

The formula for the area of the triangle is:

\displaystyle A=24x^2

When <em>x</em> = 3, the area is 216 square centimeters.

When <em>x </em>= 2.4, the area is 138.24 square centimeters.

And when <em>x</em> = 5, the hypotenuse of the triangle is 50 centimeters.

Step-by-step explanation:

We are given a right triangle with a height of 8<em>x</em> and a base of 6<em>x</em>.

The area of a triangle is given by the formula:

\displaystyle A=\frac{1}{2}bh

So, by substitution:

\displaystyle A=\frac{1}{2}(8x)(6x)=24x^2

When <em>x </em>= 3, the area will be:

\displaystyle A(3)=24(3)^2=216\text{ cm}^2

And when <em>x</em> = 2.4, the area will be:

A(2.4)=24(2.4)^2=138.24\text{ cm}^2

When <em>x </em>= 5, the height will be 8(5) = 40 cm and the base will be 6(5) = 30 cm.

By the Pythagorean Theorem:

a^2+b^2=c^2

So:

(40)^2+(30)^2=c^2

The hypotenuse will be:

c=\sqrt{1600+900}=\sqrt{2500}=50\text{ cm}

2 feet to 2 yards ratio
vredina [299]

Answer:

\frac{1}{3}

Step-by-step explanation:

Three feet make a yard, so 2 yards is 6 feet

\frac{2}{6}  If we divide the top (numerator) and the bottom (denominator) by 2 we get

\frac{2}{6} ÷ \frac{2}{2} = \frac{1}{3}
