Answer:
p = 923.2 millibar
Step-by-step explanation:
Given that,
The wind velocity can be described by the function as follows :
[tex]v(p)=5.7\sqrt{998-p}[/tex]
Where
p is the air pressure in millibar
Put v = 49.3 m/s in the above function.
[tex]49.3=5.7\sqrt{998-p}[/tex]
Squaring both sides,
[tex]49.3^2=(5.7\sqrt{998-p})^2\\\\2430.49=32.49(998-p)\\\\\dfrac{2430.49}{32.49}=(998-p)\\\\74.80=(998-p)\\\\p=998-74.80\\\\p=923.2\ mbar[/tex]
So, the required pressure is equal to 923.2 millibar.

7. A car drives 50 miles in the first hour on the road, 70 miles during the 2nd hour and 10 miles for 1/2 hour (traffic jam), then 60 miles in the final half hour of the trip. What was the average speed for the entire trip?
Answer:
Step-by-step explanation:
Average Speed = Total Distance / Total Time
Total Distance = 50+ 70 + 10 + 60 = 190 Miles
Total Time = 1 + 1 + 1/2 + 1/2 = 3 hours
Average speed = 190 / 3 = 63.3 mph
Using n = 3.14, find the area of a circle with a radius of 7.
Round your answer to the nearest hundredth.
Area of a circle = pi x r^2
Area = 3.14 x 7^2

What is the sum of the interior angles of the polygon pictured below?
The shape has 9 sides.
Sum of interior angles = (n-2) x 180, where n is the number of sides.
Sum of interior angles = (9-2) x 180 = 7 x 180 = 1,260 degrees.
Answer:
Solution :-We have
Side of polygon = 9
So,
By using the formula
(n - 2) × 180
(9 - 2) × 180
7 × 180
1260⁰

In cm, the lengths of the sides of a rectangle are 30 and 24. Find the nearest degree the measure of the angle formed by a diagnol and one of the longer sides
Answer:
38.42cm
Step-by-step explanation:
Given that the length of the sides of a rectangle are 30 cm and 24 cm.
The length of the diagonal can be obtiaed using Pythagoras rule
Length of the diagonal = hypotenus
Hypotenus = sqrt(opposite ² + adjacent ²)
Opposite and adjacent sides are 30cm and 24 cm
Hypotenus = sqrt(30² + 24²)
Hypotenus = sqrt(900 + 576)
Hypotenus = sqrt(1476)
Hypotenus = 38.419
Length of diagonal = 38.42cm
Answer:
find the size of angle O to the nearest degree
You have total coins for a total of $. . You only have quarters and dimes. Let represent the number of quarters and represent the number of dimes.
Answer:
[tex]Quarters = 41[/tex]
[tex]Dimes = 18[/tex]
Step-by-step explanation:
Given
[tex]Coins = 59[/tex]
[tex]Worth = \$12.05[/tex]
[tex]d = dimes[/tex]
[tex]q = quarters[/tex]
Required
The number of each coin
The total coins can be represented as:
[tex]d + q = 59[/tex]
[tex]1\ quarter = \$0.25 \\ 1\ dime = \$0.10[/tex]
So, the worth of the coin is:
[tex]0.25q + 0.10d = 12.05[/tex]
The equations to solve are:
[tex]0.25q + 0.10d = 12.05[/tex]
[tex]d + q = 59[/tex]
Make d the subject in: [tex]d + q = 59[/tex]
[tex]d =59 - q[/tex]
Substitute [tex]d =59 - q[/tex] in [tex]0.25q + 0.10d = 12.05[/tex]
[tex]0.25q + 0.10(59 - q) = 12.05[/tex]
[tex]0.25q + 5.9 - 0.10q = 12.05[/tex]
Collect like terms
[tex]0.25q - 0.10q = 12.05 - 5.9[/tex]
[tex]0.15q = 6.15[/tex]
Solve for q
[tex]q=\frac{6.15}{0.15}[/tex]
[tex]q=41[/tex]
Substitute [tex]q=41[/tex] in [tex]d =59 - q[/tex]
[tex]d = 59 - 41[/tex]
[tex]d = 18[/tex]
So:
[tex]Quarters = 41[/tex]
[tex]Dimes = 18[/tex]
(2x-7)(5x+75)=0
Solve this using factoring, what are the two x’s?
Note : a × b = 0 ==》 a = 0 Or b = 0
_________________________________
( 2x - 7 )( 5x + 75 ) = 0
2x - 7 = 0 ===》 2x = 7 ===》 x = 7 / 2
===》 x = 3.5
Or
5x + 75 = 0 ==》 5x = - 75 ==》 x = - 75 / 5
==》x = - 15
Step-by-step explanation:
(2x-7)(5x+75)=0
2x(5x+75) -7 (5x+75)=0
10x^2 + 150x - 35x - 525 =0
10x^2 + 115x - 525 =0
5(2x^2 + 23x - 105 ) =0
2x^2 +30x-7x - 105 =0
2x ( x + 15 ) -7 ( x + 15) = 0
(2x-7) (x + 15) =0
so, 2x-7=0 and x+15 =0
x = 7/2 and x = -15

Answer:
Angle 6 = 46°
Angle 7 = 134°
Angle 8 = 77°
Step-by-step explanation:
Angle 6 = 180 - 134 (Due to the angles on a straight line add up to 180 property)
Angle 6 = 46°
Angle 7 = 180 - 46
Angle 7 = 134°
360 = 56+148+(2 x Angle 8)
2 x Angle 8 = 360-204
2 x Angle 8 = 156
Angle 8 = 78°

a.
y = 2 x
b.
y = 2 x minus 3
c.
y = 2
d.
y = 2 x + 10
Please select the best answer from the choices provided
A
B
C
D
Answer:
c). y = 2
Step-by-step explanation:
We can check a line by inputting the x and y from (x, y) into the equation.
For a. y = 2x we get
2 = 2*10 and 2 = 2*(-3), both of those are false
For b. y = 2x - 3 we get
2 = 2*10 - 3 and 2 = 2*(-3) + 10, both of those are false again
For c. y = 2 we get
2 = 2 and 2 = 2, both of those are true, so this is the right answer.
For d. y = 2x + 10 we get
2 = 2*10 + 10 and 2 = 2*(-3) + 10, both of those are false
Alternatively, we can solve the equation y = ax + b (this gives a single answer for any two points with different x's).
y = ax + b
We input (x, y) as (10, 2) and (-3, 2)
2 = a*10 + b = 10a + b
2 = a*(-3) + b = b - 3a
so we have
10a + b = b - 3a
13a = b - b
13a = 0
a = 0
Now we ca use a = 0 to solve either of the equations above:
2 = 10a + b
2 = 10*0 + b
2 = b
so with a=0 and b=2 we get the answer
y = 0*x + 2
y = 2
Which brings us to answer c. again.
x+10=2x-4 what does x=
Answer:
x = 14
Step-by-step explanation:
x + 10 = 2x - 4
x + 10 - 10 = 2x - 4 - 10
x = 2x - 14
x - 2x = 2x - 2x - 14
- x = - 14
- x ÷ - 1 = - 14 ÷ - 1
x = 14

Determine whether the conclusion is valid. Explain. You want to determine the number of students in your school who have visited a science museum. You survey 50 students at random. Twenty have visited a science museum, and thirty have not. So, you conclude that 40% of the students in your school have visited a science museum.
Answer: The conclusion is valid
Step-by-step explanation:
Number of students surveyed = 50
Number of students who visited a science museum = 20
Number of students who haven't visited a science museum = 30
Percentage of student that have visited a Science museum:
= 20/50 × 100
= 40%
The conclusion is valid based on the calculation.
