Step-by-step explanation:
What is the volume of a spherical shell with inner radius 7 and outer radius 8?
The formula for the volume of a sphere is given as;
= 4/3 × π × r³
From the above question:
inner radius 7 and outer radius 8
Hence, the volume of a sphere with
inner radius 7 and outer radius 8 is calculated as:
V = (4/3 × π × 8³ ) - (4/3 × π × 7³)
V = 4/3 × π ×(8³- 7³)
V = 4/3 × π × (512 - 343)
V = 4/3 × π × 169
V = 707.9055446 cm³
V = 707.9 cm³

The hour hand on a clock moves 30° each hour. Which fraction of a circle does the hour hand move in 4 hours?
Answer:
1/3
Step-by-step explanation:
If the hour hand moves 30° each hour and there are 12 hours on the clock, the total degree it would move in 12 hours = 12 x 36 = 360 degrees
degrees moved in 4 hours = 4 x 30 = 120
fraction = 120 / 360
to express in its simplest form, divide both numerator and the denominator by 120
= 1/3

A dealer purchased 250 bulbs for Rs10 each. However, 12 bulbs got fused which he had to throw away. He sold the remaining bulbs at Rs 12 each. Find the gain or loss per cent in the dealing.
Answer:
CP of 1bulb =Rs10
CP of 250bulbs=Rs2500
Number of defective bulbs 12
remaining bulbs =250−12=238
SP of 1bulb =Rs12
SP of 238bulbs=Rs2856

Answer:
145
Step-by-step explanation:
Supplementary angles add up to equal 180 degrees
Thus, ∠ABC + ∠DEF = 180°
If ∠ABC = 35
Then 35 + ∠DEF = 180
180 - 35 = 145
Hence, ∠DEF = 145

Strictly increasing functions:
Let a function f(a) for x = a, then,
f(a + h), for x = a + h,
If f(a + h) > f(a), we say this a strictly increasing function, as with increase in x, f(x) also increases.
In the given graph, there are straight lines so you can say increasing interval would have +ve slope.
For x = -5 to -4, it increases = [-5, -4]
For x = 1 to 3, it increases = [1, 3]
Answer: [-5, -4] , [1, 3]

At a point on the ground 50 feet from the foot of a tree, the angle of
elevation to the top of the tree is 53 degrees. Find the height of the tree.
Round to the nearest hundredths.
Answer:
66.35 feet
Step-by-step explanation:
We solve the above question using the Trigonometric function of Tangent
= tan θ = Opposite/Adjacent
θ = 53°
Opposite = Height of the tree = h
Adjacent = Point of the ground from the foot of the tree = 50 ft
Hence,
tan 53 = h/50ft
Cross Multiply
h = tan 53 × 50ft
h = 66.352241081 ft
Approximately to the nearest hundredth, the height of the tree = 66.35 feet

SOLVE FOR X PLEASEEE HELP
Answer:
2.2857
Step-by-step explanation:
To solve this I'm going to find Angle A
I have the adjacent and opposite side so using TOA is easiest
let a= angle
tan(a)=4/7
a=29.74488
Now that we have the angle A we can only look at triangle ABC
To solve for x we use TOA again
tan(29.74488)=x/4
4tan(29.74488)=x
x=2.2857
Answer:
2.28
Step-by-step explanation:
∆ABC~∆ADE
So, x/4=4/7
7x=16
x=16/7
x=2.28
