Answer:
x = 9
Step-by-step explanation:
(x+1)²-(x-1)² = 6(x-3)
x²+2x+1-x²+2x-1 = 6x-18
x²-x²+2x+2x+1-1 = 6x-18
4x = 6x-18
4x-6x = -18
-2x = -18
x = -18/-2
x = 9
Lance is an enthusiastic cyclist.
He uses an app on his phone to track each of his cycling sessions.
Below is shown some information about his last three.
In Lance’s last three cycling sessions.
(i) What was the shortest distance cycled?
(ii) What was the longest time that he cycled for?
(iii) Work out Lance’s cycling time.
Answer:
17.25 ; 1:01:13 ; 4 hours 47 minutes, 38 seconds
Step-by-step explanation:
From the picture attached :
The shortest distance cycled :
17.25 < 25.80 < 27.42
Hence, shortest distance cycled is : 17.25
Shortest cycling time :
1:01:13 < 1:50:05 < 1:56:20
Hence, shortest distance cycled is : 1:01:13
Total cycling time:
1:01:13 + 1:50:05 + 1:56:20
1 + 1 + 1 = 3 hrs
01 + 50 + 56 = 107 = 107/60 = 1 hr 47 minutes
13 + 05 + 20 = 38 seconds
Total cycling time :
(3 + 1 hr 47 minutes + 38 seconds) = 4 hours 47 minutes, 38 seconds

Angle SPR and angle RPQ are complementary. Find the measure of angle RPQ.
Answer:
53 degrees
Step-by-step explanation:
Complimentary angles are angles whose sum equals 90 degrees.
90-37 = 53
Answer:
m∠RPQ = 53°
53 degrees
Step-by-step explanation:
When two angles are complementary angles, it means they add up to 90 degrees (Ex: a 10° angle and 80° angle would be complementary).
Therefore, if ∠SPR and ∠RPQ are complementary, then
m∠SPR + m∠RPQ = 90°
since you are given that m∠SPR = 37°, you can plug that in for m∠SPR to find m∠RPQ:
m∠SPR + m∠RPQ = 90°
37° + m∠RPQ = 90°
m∠RPQ = 90° - 37°
m∠RPQ = 53°

If the base angles of a triangle are congruent, use the Law of Sines to show the triangle is isosceles.
Answer:
The Isosceles Triangle Theorem States that if a triangle contains 2 congruent sides, then the angles opposite those sides are congruent. This theorem can be proved using the Law of Sines: The Law of Sines states that: asinA=bsinB=csinC If a=c, making △ABC an isosceles triangle, then asinA=asinC!

Answer:
∠MNQ = 31
Step-by-step explanation:
Set ∠MNQ and ∠NQP equal to each other.
∠MNQ = ∠NQP
5c + 6 = 7c - 4
10 = 2c
c = 5
Then substitute back into ∠MNQ.
∠MNQ = 5c + 6
∠MNQ = 5(5) + 6
∠MNQ = 25 + 6
∠MNQ = 31
The students in Mr.Collin's class used a surveyor's measuring device to find the angle from their location to the top of a building. They also measured their distance from the bottom of the building. The diagram shows the angle measure and the distance. To the nearest foot, what is the height of the building?
a. 105 ft
b. 116 ft
c. 32 ft
d. 54 ft
The height of the building is approximately 105 ft.
According to the question,
We have the following information:
The angle made from their location to the building = 59°
The distance of the building from their location = 63 ft
Now, we can find the height of the building by using trigonometric function of tan.
We know that tan is equal to perpendicular/base.
In this case, perpendicular is the height of the building and base is the distance of the location from the building.
We have:
Tan 59° = Height of the building/distance of the building from the location
We know that the value of tan 59° is 1.6643.
Let's take the height of the building to be H ft.
1.6643 = H/63
H = 1.6643*63 ft
H = 104.85 ft
Now, this number can be rounded off to 105 ft.
Hence, the correct option is a.

What is the surface area of a sphere that
has a diameter of 12 inches?
Answer: The surface area is 452.39in²
Step-by-step explanation:
Formula
A=4πr²
d= 2 r
Solving for A
A=πd²=π·12²≈452.38934in²
The surface area of a sphere that has a diameter of 12 inches is 452.39 in².
To solve the question, we need to know what the surface area of a sphere is.
What is the surface area of a sphere?The surface area of a sphere is given by A = 4πr² where
r = radius of sphere = d/2 where d = diameter of sphere.Given that d = 12 inches, r = d/2 = 12 in/2 = 6 in
Substituting the value of r into A, we have
A = 4πr²
A = 4π × (6 in)²
A = 4π × 36 in²
A = 144π in²
A = 452.39 in²
So, the surface area of a sphere that has a diameter of 12 inches is 452.39 in².

The perimeter of this shape is 40cm
Calculate the value of x
Answer:
x = 8
Step-by-step explanation:
The perimeter (P) is calculated as
P = 2(l + b) ← l is length and b is breadth
Here l = 12 and b = x , P = 40, then
2(12 + x) = 40 ( divide both sides by 2 )
12 + x = 20 ( subtract 12 from both sides )
x = 8

a varies jointly as the square root of the product of b and c. if a = 24 when b = 8 and c= 2 , find v when a = 48 and c = 4
Answer:
b = 16
Step-by-step explanation:
× stands for varies
a × √bc,
a = k√bc,
when a = 24, b = 8, c= 2
a = k√bc
24 = k√8•2
24 = k√16
24 = 4k
dividing both sides by 4
k = 24/4
k = 6
a = 6√bc (standard equation)
find b when a = 48 and c = 4
a = 6√bc
48 = 6√b•4
dividing both sides by 6
48/6 = √b•4
8 = √b•4
squaring both sides
8^2 = b•4
64 = b•4
b = 64/4
b= 16.
Thrrefore when a = 48, c = 4, b = 16.
