Answer:
Step-by-step explanation:
There are only two ways to roll a sum of 11 (5,6),(6,5) out of 36 possible outcomes so
P(11)=2/36=1/18
as a rounded decimal 0.056
Both planes leave from Kansas City at the same time.
Plane A flies due West.
Plane B flies due South.
After 2.5 hours, how far is Plane A from Plane B?
A. 1,425.0
B. 1,322.0
C. 1,258.5
The distance between Plane A from Plane B is,
⇒ 1,425.0 m
The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.
Given that;
Speed of Plane A = 450 mph.
Speed of Plane B = 350 mph.
And, Both planes leave from Kansas City at the same time.
Here, Plane A flies due West.
And, Plane B flies due South.
Now, Distance cover by plane A in 2.5 hours is,
⇒ 450 × 2.5
⇒ 1125 m
And, Distance cover by plane B in 2.5 hours is,
⇒ 350 × 2.5
⇒ 875 m
Thus, The distance between Plane A from Plane B is,
⇒ √1125² + 875²
⇒ 1425.0 m

How many time should the graph of this function intersect at the x-axis?
A. 3
B. 2
C. 1
D. 0
Answer:
3 miles per hour
Step-by-step explanation:
We know
Jayla ran the first 3 miles of a 5-mile race in an hour.
What was her average rate, in miles per hour, for this first part of the race?
Average rate = Distance / Time
We take
3 ÷ 1 = 3 miles per hour
So, the answer is 3 miles per hour.
Answer: D = 44/9
Step-by-step explanation:
Subtract 8/9 from both sides, after you're left with D = -4 - 8/9
Now simplify D = -4 - 8/9 to get D = 44/9
Answer:
x² + y² = 85
Step-by-step explanation:
Using the expansion
(x - y)² = x² + y² - 2xy , then
x² + y² - 2xy = (x - y)² ( add 2xy to both sides )
x² + y² = (x - y)² + 2xy ← substitute given values
= 9² + 2(2)
= 81 + 4
= 85
