Answer:
Slope: -3
Equation: [tex]y=-3x-5[/tex]
Step-by-step explanation:
As x increases by 1, your y decreases by 3, making the rise over run [tex]-3/1=-3[/tex]. That becomes the m in your y=mx+b equation, and since you have the y intercept, you can just plug and chug.
If I helped, a brainliest answer would be greatly appreciated!
Answer:
Slope = -3

a)ΔFHA is similar to ΔZIA by hypotenuse side test.
reason:- angle H and angle I are of 90 degrees.
b) FH/ ZI = HA/ IA = FA/ ZA
angle F = angle Z, angle H = angle I , angle angle A = angle A
The scale factor is 3/2......( HA/IA = 12/8 = 3/2)
c) IZ = 3.3 ....( FH/ IZ = 3/2, 5/ IZ = 3/2, IZ = 10/3 = 3.33)

Answer:
a) 5/7
b) 2/3
c) 1/6
Step-by-step explanation:
a) 2/7 + 3/7
since the denominators are both 7 we use 7 as the LCM ( lowest common multiple)
2+3/7 = 5/7
b) 5+7/8 = 12/8. 4 can go into both numbers so it gives 3/2

A water tank holds 1,216 gallons but is leaking at a rate of 5 gallons per week.
A second water tank holds 1,520 gallons but is leaking at a rate of 9 gallons per week.
After how many weeks will the amount of water in the two tanks be the same?
Answers
Answer:
im pretty sure it'd be 76 weeks!
Step-by-step explanation:
one water tank holds 1216 and loses 5 gallons/week
another water tank holds 1520 gallons and loses 9 gallons/week
youd make an equation:
1216-5x=1520-9x
(each side being the amount of water the tank can hold minus the amount it loses per week [x])
heres how you execute the equation:
1216-5x=1520-9x
-5x=1520-1216-9x
-5x=304-9x
-5x+9x=304
4x=304
x=304/4
76
after you do the equation, you get x=76, meaning 76 weeks! :-)

The angle of depression from an air traffic control tower to an airplane on the runway is 72 degrees. If the tower is 354 feet tall, how far is the airplane from the base of the tower?
Answers
Answer:
115.02 feet
Step-by-step explanation:
The angle of depression from an air traffic control tower to an airplane on the runway is 72 degrees. If the tower is 354 feet tall, how far is the airplane from the base of the tower?
We solve this question using the Trigonometric function of tan
tan x = Opposite/Adjacent
x = Angle of depression = 72°
Opposite = Height of the tower = 354 feet
Adjacent = Distance of the airplane from the base of the tower = y
Hence,
tan 72 = 354/y
Cross Multiply
tan 72 × y = 354
y = 354/tan 72
y = 115.02157247 feet
Approximately = 115.02 feet
Therefore, the distance of the airplane from the base of the tower is 115.02 feet

A sphere is rolled between two sharp, parallel blades that are 77 centimeters apart. Both blades cut off a piece of the sphere cleanly, leaving two parallel circular faces with radii of 39 and 60 cm. What is the radius of the sphere?
Answers
Answer:
The radius of the sphere is approximately 62.71 cm
Step-by-step explanation:
The question relates to the definition of a sphere
The given parameters are;
The distance between the sharp parallel blades through which the sphere is rolled = 77 centimeters
The radii of the circular faces left by cutting the sphere with the blade = 39 cm and 60 cm
From the triangles formed by the cross-section of the sphere, we have;
AB ║ DE Given
∠A ≅ ∠E, ∠D ≅ ∠B Alternate angles
∠C ≅ ∠C by reflective property
∴ ΔABC ~ ΔDCE by Angle-Angle similarity theorem
CF/CG = AB/DE = 78/120 = 13/20
CF = CG × 13/20
CF + CG = 77
∴ CG × 13/20 + CG = 77
33·CG/20 = 77
∴ CG = 140/3
CF = 13/20 × CG = 13/20 × 140/3 = 91/3
CF = 91/3
The diameter of the sphere AE = AC + EC
By Pythagoras's theorem
AC = √(FA² + CF²) = √(39² + (91/3)²) = 13·√(130)/3
EC = √(CG² + GD²) = √((140/3)² + 60²) = 20·√(130)/3
∴ AE = AC + EC = 13·√(130)/3 + 20·√(130)/3 = 11·√(130)
The diameter, 'D', of the sphere, AE = 11·√(130)
The radius of the sphere = D/2 = 11·√(130)/2 ≈ 62.71 cm
