Answer:
∠ SPQ = 75°
Step-by-step explanation:
The sum of the 4 angles in a quadrilateral = 360°
Subtract the sum of the 3 angles from 360 for ∠ SPQ
∠ SPQ = 360° - (90 + 74 + 121)° = 360° - 285° = 75°
Answer:
3x-5y
Step-by-step explanation:
All you need to do here is combine like terms.
13x - 10x = 3x
2y - 7y = -5y
When they ask you to simplify the expression, they're not looking for you to solve anything. You just have to combine what you can. :)
Answer:
Seventh term is 64
Sum of the first seven terms is 127
Step-by-step explanation:
The common ratio is 2
n = 7 and the first term is 1. So,
Seventh term is 64
Sum of the first seven terms is 127
ANSWER
The correct answer is 4.6
EXPLANATION
Since U is the midpoint of |RS|,
U being the midpoint of RS means, it is in the middle of R and S.
So if from R to U is 2.3, then from U to S is also 2.3.
This is an implication that
See diagram in the attachment.
The probability that the marble she chooses is not blue can be solve in two ways.
first way: is to solve the probability of red and yellow marbles, so that is the probability of not getting blue
P = 6 + 8 / 6 + 8 + 18P = 7/16
2nd way: is to solve the null of blue or 1 minus the probabilty of choosing blue marble
P = 1 - (18 / 6 + 8 + 18)P = 1 - ( 9 / 16)P = 7/16
