1)Russell from Up has 400 balloons. The balloons are red, yellow, blue and purple. Forty percent of the balloons are red, 5% are
Nastasia [14]

Answer:

Blue Ballon = 16

Yellow Ballon = 23

Green Ballon = 26

Red Ballon = 32

Total puffs = 1000

23y + 16(2y) + 32y + 26(y/2) = 1000

23y + 32y + 32y + 13y = 1000

100y = 1000

y = 1000/10

y = 10

Therefore, russell

filled 10 yellow balloons.

Luda [366]

Answer:

Hence proved that m∠AOD = m∠BCD.

Step-by-step explanation:

Given:

A Trapezoid with AC and BD as diagonals with O as intersection point to it.

Four angles formed at A and D are equal.

To Prove:

m∠AOD = m∠BCD

Proof:

Consider a Quadrilateral ABCD as trapezoid with diagonals as AC and BD

(Refer the Attachment).

And AB=CD which means the Quadrilateral ABCD isosceles in nature

i.e. angle A=angle D

Now  

Consider triangle AOD and triangle BCD

Apply sum of all angles of triangle is 180.

And also

m∠2+∠AOD+m∠3=180

∠AOD=180-m∠2-m∠3..............equation(1)

And for Triangle BCD

m∠BCD=180-m∠3-m∠4,.....................Equation(2)

∠A=∠D................ as Quadrilateral is  Isosceles.

i.e.∠2=∠3

That means by transitive property,

∠1=∠4=∠3=∠2

Using this values in above equation(1) we get ,

∠AOD=180-∠3-∠4.......................(3)

Now comparing equation 2 and 3 we get

RHS is equal for both equation that means LHS is also equal .

Therefore ∠AOD=∠BCD

Hence proved.

Last year, there were b pies baked for the bake sale. This year, there were 158 pies baked. Using b, write an expression for the
irakobra [83]
<h3>Answer:  b+158</h3>

We simply add the two subtotals to get the grand total. If we knew the value of b, then we'd be able to find an actual numeric result.

For example, let's say b = 100 pies were baked last year. That would mean b+158 = 100+158 = 258 pies were made over the two year period. However, since we don't know what b is, we just leave b+158 as is.
