Phantasy [73]

Answer:

6. x + x + 14 = 90

2x + 14 = 90

2x = 76

x = 38

angle b = 38 + 14 = 52°

7. angles on a straight line add up to 180°

x + x - 32 = 180

2x = 212

x = 106°

angle d = 106 - 32 = 74°

8. vertically opposite angles are equal

7x - 80 = 3x

-80 = -4x

20 = x

angle 1 = 7(20) - 80 = 60°

angle 2 = 3(20) = 60°

Find the value of the arc x.

julsineya [31]

Answer:

216°

Step-by-step explanation:

Both chords are the same length, so the left and right arcs are both 72°. The whole circle is 360°, so:

72° + 72° + x = 360°

x = 216°

A pitcher of punch holds 2 gallons if 9 people share the entire pitcher how much do that get a peice

kirza4 [7]

To find how much each person will get, you have to divide the amount available by the people. There are 2 ways I believe we can do this.
First way
Let's divide.
2÷9= 2/9

Each person would get 2/9 of a gallon if they shared it.

≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡≡
Second way
I believe it would be easier to convert this into cups. There are 16 cups per gallon.
16×2= 32
Let's divide that by 9.
32÷9= 3 5/9 cups per person.

Each person would receive 2/9 of a gallon.

Multiplying fractions is just multiplying the numerators together and the denominators together.

$\sf\dfrac{4}{7}\times\dfrac{1}{4}\rightarrow\dfrac{4\times 1}{7\times 4}\rightarrow\dfrac{4}{28}\rightarrow\dfrac{1}{7}$

$\sf\dfrac{4}{7}\times\dfrac{1}{6}\rightarrow\dfrac{4\times 1}{7\times 6}\rightarrow\dfrac{4}{42}\rightarrow\dfrac{2}{21}$

To find out which one is bigger, we need a common denominator. The LCM of 7 and 21 is 21, so convert the first fraction into a denominator of 21. 7 goes into 21 three times, multiply this to the numerator and denominator:

$\sf\dfrac{1}{7}\rightarrow\dfrac{1\times 3}{7 \times 3}\rightarrow\dfrac{3}{21}$

Now just compare the numerators to see which one is bigger.

$\sf\dfrac{3}{21}>\dfrac{2}{21}$ therefore, $\sf\dfrac{4}{7}\times\dfrac{1}{4}>\dfrac{4}{7}\times\dfrac{1}{6}$
