Answer:
60÷12=0.2
0.2miles per minute
0.2x45=9miles
Answer:
9 miles
Step-by-step explanation:
The speed of 12 miles per hour means that for every hour, Clare is 12 miles further from the starting point.
1 hour ----- 12 miles
Since an hour is equivalent to 60 minutes,
60 mins ----- 12 miles
We can divide both sides by 60 to find the distance travelled per minute.
1 min ----- 12 ÷60= 0.2 miles
Multiply both sides by 45 to find the distance travelled in 45 minutes:
45 mins ----- 0.2(45)= 9 miles
Given that the starting position is at zero, Clare's position is at 9 miles after 45 minutes.

Expand and simplify
(x + 5)(x-9)
Answer:is
=x(x-4)-45
Step-by-step explanation:q= (x+5) (x-9)
in the mathematical rules when the variables are in the brackets it means we have to remove the brackets by,multiplying the first variable to the second variable in another bracket, and then so on.
=x^2-9x+5x-45

Evelyn watches airplanes take off at an airport. She is 200 meters away from where the planes take off from the runway. The initial angle at takeoff of a plane is 12°. A triangle is shown. The triangle is made up of the initial takeoff of the plane, where the plane currently is in the sky, and where Evelyn is watching the plane. The angle of takeoff is 12 degrees. The distance from the initial takeoff to Evelyn is 200 meters and the distance from the initial takeoff to the plane apostrophe s current position is 100 meters. What is true when the plane is 100 meters away from takeoff? Check all that apply. The given information is the SSS case. The given information is the SAS case. The given information is the SSA case. Evelyn is approximately 104 meters from the plane. The angle of elevation of the plane is 12°.
Two triangle are congruent when the shape and size of both the triangle are same.
The given information is the SAS case. Thus the option B is the correct option.
What is triangle congruence theorem?Two triangle are congruent when the shape and size of both the triangle are same.
Triangle congruence theorem are-
Angle-Side-Angle theorem (AAS)- This theorem states that two triangle is congruent when two angle and one side of the triangle are respectively equal to the two angles and same side of the other triangle.Side-Side-Side theorem (SSS)- When the three sides of the one triangle is equal to the three sides of the other triangle respectively, then the triangle are congruent. Side-Angle-Side theorem (SAS)- Two sides and the included angle of are equal to the two sides and one angle of other triangle respectively.Given information-
The distance of the Evelyn from the airplane is 200 meters.
The initial angle at takeoff of the plane is 12 degrees.
Evelyn is approximately 104 meters from the plane.
The angle of elevation of the plane is 12°.
The triangle made for this situation is attached below.
As in the shown triangle below this question. The distance of Evelyn from the initial takeoff of the plane is shown.
This distance is equal to the base of the triangle. Therefore we get the one side of the tingle.
Now the plane is flied 100 meters, which gives the value of another side of the triangle as shown in the image below attached.
Angle of elevation of the plane is 12 degrees, which gives the one angle of the triangle.
Thus we have one side equal to the 100 meters, one angle equal to the 12 degrees and another side with equal to the 200 meters.
Thus it is the case of side angle side.
Hence, the given information is the SAS case. Thus the option B is the correct option.

Geometry
1. The size of angle x
2. The size of angle y
3. The size of angle z
Answer: x=40, y=70,
Step-by-step explanation:
To find angle x you first need to find O. You do this by subtract 180-40. Then you would get 140. Take this 140 and subtract it by 180. Your answer for x should be 40.
To find angle y you first need to know that x=40. Taking this you would subtract it by 180. It would leave you with 140. Taking 140 your going to dive it in half to get y. Your answer for y should be 70.
Sorry I'm not sure how to find z.

First taking small triangle,
Perpendicular(P') = 5cm
Base(B) = y (let)
Hypotenuse(H') = 12cm
so,
(H')² = (P')² + (B)²
(12)² = (5)² + (y)²
(y)² = 144 - 25
(y)² = 119
Now taking big triangle,
Perpendicular (P) = 12+5 = 17cm
Base (B) = y (already supposed)
Hypotenuse (H) = x
so,
(H)² = (P)² + (B)²
(x)² = (17)² + (y)²
(x)² = 289 + 119 = 408
x = √408

Answer:

x = 10
substitute x=10 to find value of 'y':
40(10) + 4y = 500
400 + 4y = 500
4y = 100
y = 25
Check:
20(10) - 4(25) should equal 100

-5 • (n + 4) ≤ 0
Divide both sides by -5
Subtract 4 from both sides which is n ≥ -4
Answer:
n = -4Step-by-step Solution:
5(n - 2) = -30=> 5n - 10 = -30=> 5n = -30 + 10=> 5n = -20=> n = -4Check:
5(n - 2) = -30 => 5(-4 - 2) = -30=> 5(-6) = -30=> -30 = -30Hence, this is correct.
