Answer:
Step-by-step explanation:
PQRS is a parallelogram with QR = 6 cm, QT = 3 cm and ∠PSR = 115°.
a). By the property of a parallelogram,
"Diagonals of a parallelogram bisect each other"
QT = TS
QS = 2(QT)
= 2(3)
= 6 cm
b). "Adjacent angles of a parallelogram are supplementary"
m∠PSR + m∠SRQ = 180°
115° + m∠SRQ = 180°
m∠SRQ = 65°
c). Since, SQ = SR = 6 cm
m∠QSR = m∠SRQ [Opposite angles of the equal sides of an isosceles triangle]
m∠QSR = 65°
By applying triangle sum theorem in ΔQSR,
m∠SQR + m∠QRS + m∠QSR = 180°
m∠SQR + 65° + 65° = 180°
m∠SQR = 50°
Answer:
C
Step-by-step explanation:
Question: 10 - 8 = 2
A = (-18)
B = 18
C = 2
D = (-2)
19) 3/8
24 - 15 = 9
9/24 = 3/8
20) 3/28
8 total people running. We want to know the probability that both the president and vice-president are girls, so we have to assume that the president is a girl first.
3/8 x 2/7 = 6/56 = 3/28
21) Travis should play the game where he has to pick either an A or B out of a hat which contains letters A, B, C, D, and E. The probability of him drawing an A or B and winning is 2/5, or 0.4. If he plays the other game, then the probability of him winning is only 1/3, or 0.33.
Probability of rolling a 2 or 3 on a die = 2/6 = 1/3 (0.33)
Probability of picking an A or B = 2/5 (0.4)
Answer:
Step-by-step explanation:
Choice A
Log 10 = 1.
So A is actually right, although it does not look it.
log(20 * x^5 ) - 1 is correct.
Choice B
Log(x^5 * 20 / 10)
log(2 x^5)
Choice B is also correct
Choice C is not correct, or if it is, I don't know how to get it. You need the 20 in there somewhere.
No! Dis not correct. The 2 is not raised to the 5th power.
And E is not correct. I'm not sure how they got it. Even + 1 is not correct. It should be -1 if that is how it is to be done.
