Question
An airplane is traveling at a constant speed of
600 miles per hour. How many feet does it
travel in 9 seconds? Remember that 1 mile is
5280 feet.
Do not include the units in your answer, and
do not use a comma in your answer
Provide your answer below:
Answer: 7920
Step-by-step explanation:
Convert 600mph to feet per hour.
600 x 5280 = 3168000 feet per hour
Convert feet per hour into seconds by dividing by 60 to get minutes and 60 again to get seconds.
3168000 / 60 / 60 = 880 Feet per second
Multiply by 9
880 x 9 = 7920 feet in 9 seconds
Diana first got 14 points with two arrows on the target. The
second time she got 16 points. How many points did she get
the third time?
(A) 17 (B) 18
(C) 19 (D) 20 (E) 22
Please answer and let me know why that answer, thank you!
Answer:
B. 18
Step-by-step explanation:
Her first two arrows landed on the same circle with 14 points. This means that 1 arrow in that circle = 7 points.
The second time, one arrow landed on the circle that carry 7 points per arrow, and the next inner circle would carry = 16 - 7 = 9 points
Therefore, if in her third throw, the two arrows landed in the inner circle that has 1 arrow recording 9 points, she would get = 9*2 = 18 points

Juan ran of a mile 2/5 every 4/7 of an hour. Find Juan’s rate in miles per hour
Answer:
Juan runs 7/10 of a mile every hour
Step-by-step explanation:
First find out how much he ran every 1/7 of an hour
2/5 x 1/4 = 4/7 x 1/4
1/10 = 1/7
1/10 x 7 = 1/7 x 7
7/10 = 1

Cindy’s square-shaped garden has side lengths of x ft. She will plant 5 tulip bulbs per square foot. How many bulbs will she plant if the garden has a side length of 8 feet?
Enter your answer in the box.
Answer:
The number of bulbs planted in the garden having side length of 8 feet is 320.
Step-by-step explanation:
Given as :
The side length of square shaped garden = x ft
The number of tulip bulbs Cindy's will plant at per square foot = n = 5
Let The number of bulb to be panted for side length of garden = L = 8 feet
Now, According to question
Since the garden is of square shaped ,
So, The area of garden = area of square = side²
I,e The area of garden = x × x ft²
Now, if the side length = L = 8 feet
So, The area of garden = L × L ft²
I.e The area of garden = 8 × 8 ft² = 64 square feet
Now, Again
∵ For the area of 1 square feet , the number of bulbs planted = 5
∴ For the area of 64 square feet , the number of bulbs planted = 5 × 64
I.e For the area of 64 square feet , the number of bulbs planted = 320
Hence The number of bulbs planted in the garden having side length of 8 feet is 320 . Answer

The sum of the angles is 180 degrees.
We can have an obtuse triangle, an acute triangle, or a right triangle.
We have,
ΔABD is similar to ΔBCD.
This means,
The corresponding sides ratio is equal.
AB/BC = BD/CD = AD/BD
AB/m = BD/7 = 11/BD
Now,
BD/7 = 11/BD
BD² = 77
BD = √77
Now,
ΔBDC
BC² = CD² + BD²
m² = 7² + 77
m² = 49 + 77
m² = 126
m = √126
Thus,
The value of m in the figure is √126.

Answer:
(x, y) = (3, 7)
Step-by-step explanation:
If you divide the second equation by 2, it becomes ...
-x +2y = 11
Adding this to the first equation gives you the value of y:
(x -y) +(-x +2y) = (-4) +(11)
y = 7 . . . . . . . . simplify
The first equation can be rearranged to give an expression for x:
x = y -4
x = 7 -4 = 3
Then the solution is seen to be (x, y) = (3, 7).

B. Same-side interior angles
Step-by-step explanation:
Angle w and angle x lie on the same side of the transversal that cut across the two parallel lines, and are also within the two parallel lines. They are therefore regarded as same-side interior angles. Same-side interior angles are supplementary.
