Answer:
2/4
Step-by-step explanation:
Change the 2 1/2 to 2 2/4
now subtract 1/4 from 2 2/4 leaving 2 1/4
Now subtract 1 3/4 from 2 1/4 in which you get 2/4
which is the answer :)
Answer:
x = 2.3
Measure of arc XY = 76° ⇒ answer (D)
Step-by-step explanation:
∵ arc XY congruent to arc YZ
∴ XY = YZ ⇒ chords subtended by equal arcs are equal
∴ 3x = 6.9 ⇒ x = 6.9/3
∴ x = 2.3
In ΔOXY
∵ OX = OY radii
∴ m∠OXY = m∠OYX
∵ m∠OXY = 52°
∴ m∠OYX = 52°
∵ The sum of angles of a Δ = 180°
∴ m∠XOY = 180 - 2 × 52 = 76°
∵ ∠XOY is central angle subtended by arc XY
∴ The measure of arc XY = m∠XOY = 76°
Mobile payments are payment transactions done with the help of a mobile phone. Think Venmo, Square Cash and Gogle Wallet, used to transfer money and even to shop at participating retailers – all with the tap of screen. According to a recent global study on mobile payment transactions, the mobile payments market was worth $550 billion in 2015 and is expected to grow more than 39% by 2020. That is explosive growth by any calculation.
But within all the buzz and investment that is flowing into this industry lies a cautionary tale, one that AnnaMaria Lusardi, director of the Global Financial Literacy Excellence Center (GFLEC) at George Washington University in Washington, D.C., explains like this: “We can make payments with the touch of a button, but the impact of this rapid innovation is not being examined.”
No because the scale factor is inconsistent while it would be neccecary to be consistent if it was similar. 19.9/15.3=1.3 while 29/25=1.16 which proves that they have an inconsistent scale factor.
