Answer:
4
____________________
Step-by-step explanation:
Just solve the equation 5-√x = 3
So, let’s solve it:
5-√x = 3 ⇔ 5-3=√x ⇔ √x = 2 ⇔ x=4
Then ?=4
:)
Step-by-step explanation:
did you give us all the information ? the equating looks cut off.
so, from what I can see we have
9(y-4) - 3y = 2(3y-2)
let's try :
9y - 36 - 3y = 6y - 4
0 = 32
so, no, this can't be it. this does not have a solution. you must have cut off some additional information.
Answer:
$269.50
Step-by-step explanation:
Between 42-49
So, you have to assume 49 students will arrive, better to have more and have left overs than get less and not find kids.
As for math you just do 49 x 5.50 = 269.5
Finally that measn the budget for the food is $269.50

Explanation:
<u>Given</u>:
- The attached figure showing circle O, chord BC, central angle BOC and inscribed angle BAC
- angle BAC = α + β
<u>Prove</u>:
<u>Proof</u>:
∠BOA +∠BOC +∠AOC = 360° . . . . . sum of arcs of a circle is 360°
2α +∠BOA = 180°, 2β +∠AOC = 180° . . . . . sum of triangle angles is 180°
∠BOA = 180° -2α, ∠AOC = 180° -2β . . . . solve statement 2 for central angles
(180° -2α) +∠BOC +(180° -2β) = 360° . . . . . substitute into statement 1
∠BOC = 2(α +β) . . . . . add 2α+2β-360° to both sides
∠BOC = 2×∠BAC . . . . . substitute given for α+β; the desired conclusion
