Just multiply the with and the length by four (considering the scale factor is 4)
3x4=12 and 7x4=28
I got y = two over three x
Answer:
The cluster from 4 p.m.–10 p.m. means that most of the texts were sent in the afternoon and evening.
More texts were sent from 6 p.m.–8 p.m. than from 8 p.m.–10 p.m.
Step-by-step explanation:
From 6 a m to 8 a m there were 15 texts,
8 to10 a m: 5, 10 a m to 12 p m: 0,
12 p m to 2 p m: 0,
2 p m to 4 p m: 0,
4 to 6 p m: 29,
6 to 8 p m: 19,
8 to 9 p m, 14,
10 p m to 12 a m: 5.
Answer:
$75 because 900 divided by 12 is 75
Step-by-step explanation:
In Δ ABC, ∠A=120°, AB=AC=1
To draw a circumscribed circle Draw perpendicular bisectors of any of two sides.The point where these bisectors meet is the center of the circle.Mark the center as O.
Then join OA, OB, and OC.
Taking any one OA,OB and OC as radius draw the circumcircle.
Now, from O Draw OM⊥AB and ON⊥AC.
As chord AB and AC are equal,So OM and ON will also be equal.
The reason being that equal chords are equidistant from the center.
AM=MB=1/2 and AN=NC=1/2 [ perpendicular from the center to the chord bisects the chord.]
In Δ OMA and ΔONA
OM=ON [proved above]
OA is common.
MA=NA=1/2 [proved above]
ΔOMA≅ ONA [SSS]
∴ ∠OAN =∠OAM=60° [ CPCT]
In Δ OAN


OA=1
∴ OA=OB=OC=1, which is the radius of given Circumscribed circle.
