Answer:
b = 20
Step-by-step explanation:
The computation is shown below
Given that
24+ 6b > 138
where
b = 10
b = 15
b = 20
So if we take b = 10
= 24 + 6(10)
= 24 + 60
= 84
B = 15
= 24 + 6(15)
= 24 + 90
= 114
B = 20
= 24 + 6 (20)
= 24 + 120
= 144
So if we take b = 20 the inequality would be true

Answer:
The volume of the cone = 101 cubic inches.
Step-by-step explanation:
Given
Radius of the cone = r = 4 in
Height h of the cone = h = 6 in
To determine
The volume in cubic inches rounded to the nearest whole number.
Using the formula to determine the volume of the cone
V = πr²h/3
substitute r = 4, h = 6, and π = 3.142 in the formula
V = (3.142) (4)²(6) / 3
V = (3.142) (4)² (2)
V = (3.142) (16) (2)
V = (3.142) (32)
V = 100.544
V ≈ 101 cubuc inches (rounded to the nearest whole number)
Therefore, the volume of the cone = 101 cubic inches.

The length of the base of an isosceles triangle is x. The length of a leg is 2x - 4. The perimeter of the triangle is 47. Find x.
Answer:
x = 11
Step-by-step explanation:
Remark
There are two legs. They are equal.
Equation
2x - 4 + 2x - 4 +x = 47 Combine like terms
Solution
5x - 8 = 47
5x - 8+8 = 47 + 8
5x = 55 Divide by 5
x = 11

A dressmaker needs to cut 12-inch pieces of ribbon from rolls of ribbon that are 6 feet in length. How many 12-inch pieces can the dressmaker cut from 10 of these rolls of ribbon?
Before you try that problem, answer the question below.
How many \textbf{inches}inches of ribbon does the dressmaker have, in total?
Answer:
60
Step-by-step explanation:
because 12 inches is one foot so there’s 6 feet per 6 feet of ribbon and there’s 10 of these ribbons so 6 times 10 is 60
The 12-inch pieces the dressmaker can cut from 10 of these rolls of ribbon will be 60 strips .
What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
It is given that the dressmaker has 720 inches of ribbon.
dressmaker needs to cut 12-inch pieces of ribbon from rolls of ribbon that are 6 feet in length.
The amount of rolls she has = 10 rolls
so,
6(strips per roll) x 10(amount of rolls) = 60 strips

Ronin kicks a ball over the gate of the first floor balcony. The function h(t)=-36t^2+288t+9 can be used to model the height of the ball where t is the time in seconds after the ball kicked and h(t) is the height in feet 1. Find the time in Devon which the ball reaches it maximum height
Answer: 4 seconds
Step-by-step explanation:
Given: The function [tex]h(t)=-36t^2+288t+9[/tex] can be used to model the height of the ball where t is the time in seconds after the ball kicked and h(t) is the height in feet.
Differentiate the given function with respect to t , we get
[tex]h'(t)=-36(2)t+288=-72t+288[/tex]
Put h'(t)=0
[tex]\Rightarrow\ -72t+288=0\Rightarrow\ t=\dfrac{288}{72}\\\\\Rightarrow\ t=4[/tex]
Also, [tex]h''(t)=-72<0[/tex]
By second derivative test, h(t) is maximum at t=4.
Hence, the time in Devon which the ball reaches it maximum height = 4 seconds

A tree cast a 16 foot long shadow on level ground a forestry student uses a clinometer to determine the sun is that a 70° angle of elevation what is the height of the tree to the nearest whole foot
Answer:
15foot
Step-by-step explanation:
The set up will give a right angled triangle.
The length of the shadow will be the hypotenuse = 16foot
The height of the tree will be the opposite = x
The angle of elevation = 70°
Using the SOH CAH TOA trig identity
Sin theta = opposite/hypotenuse
Sin 70 = x/16
x=16sin70
x = 15.04feet
Hence the height of the tree to the nearest whole foot is 15foot
