what is the value of 2^-3 as a fraction
Answer:
1/8
Step-by-step explanation:
2⁻³ = 1 / 2³ = 1 / (2*2*2) = 1/8
so the minus sign in the exponent means you can put that factor in the denominator without the minus sign.

HELP PLEASE I REALLY NEED HELP ILL GIVE BRAINLIEST
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 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?
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! :-)

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?
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

Work out a) 2/7+3/7 b) 5/8+7/8 c) 2/3-1/2
Answer:
a) 5/7 b) 12/8, 1 4/8
Step-by-step explanation:
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
c) 2/3 - 1/2 multiply the denominator since they are different (3×2) =6
4-3/6 = 1/6

How would you find the percent of discount if the sale price is $61.75 and the original price is $95
Answer:
Sale Price = $61.75 (answer). This means the cost of the item to you is $61.75. You will pay $61.75 for a item with original price of $95 when discounted 35%. In this example, if you buy an item at $95 with 35% discount, you will pay 95 - 33.25 = 61.75 dollars.

Thanks for helping, I really appreciate it
Answer:
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)
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?
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 frog is at the bottom of a 25-foot well. Each day he climbs up
5 feet, and each night he slips down 2 feet. How many days will
it take the frog to reach the top of the well?
The frog reached the top on the
day.
Be prepared to explain how you got your answer.
Answer:
25/3
Step-by-step explanation:
In 1 day we have daytime and night time each 12 hrs
in the day time he climbs 5ft and at night he slips 2 ft
meaning he climbs a total of 3ft(5-2) each day
so to get the number of days he climbed uts 25ft /3 ft
Therefore he takes 25/3 days to reach the top
