At the 6th grade school dance there are 132 boys, 88 girls and 14 adults. What is the ratio of boys to girls
spayn [35]
The adult's genders aren't specified so that doesn't matter.

There are 132 boys for every 88 girls

(132:88) 

To simplify the ratio, divide both numbers by the GFC (Divide both sides by 44)

3:2 

There are 3 boys for every 2 girls

-1/7(14+28p)-13=4(1/2p-3)-6p
Julli [10]

Answer:

No Solution

Step-by-step explanation:

<u>-1/7</u>(14+28p)-13=<u>4</u>(1/2p-3)-6p

-2-4p-13=2p-12-6p

rearrange the question so like terms are next to each other

<u>-2-13</u>-4p=<u>2p-6p</u>-12

-15-4p=-4p-12

add 12 to both sides

-3-4p=-4p

add 4p to both sides

-3=0

No solution

Please Help me it’s geometry

Answer:

Option C.

Step-by-step explanation:

Given: In \Delta OPQ,m\angle O=107^{\circ},m\angle P=28^{\circ}.

In \Delta OPQ,

m\angle O+m\angle P+m\angle Q=180^{\circ}    (Angle sum property)

107^{\circ}+28^{\circ}+m\angle Q=180^{\circ}

135^{\circ}+m\angle Q=180^{\circ}

m\angle Q=180^{\circ}-135^{\circ}

m\angle Q=45^{\circ}

Now,

m\angle O>m\angle Q>m\angle P

In a triangle, the greatest angle has largest opposite side and smallest angle has smallest opposite side. So, we conclude that

PQ>OP>QO

Therefore, the correct option is C.
