The inequality which will represent the disease killing of trees in the national forest is 691255[tex]0.985^{t}[/tex]<621859 and the value of t is t<7.
What is inequality?An inequality is just like an equation which is presented in greater than sign, less than signs. It also shows relationship between variables like an equation does.
How to form inequality?Total trees present in the beginning=691255
rate at which trees are killed by untreatable disease=1.5%
So the inequality can be formed as under:
691255[tex](1-0.015)^{t}[/tex]<621859
[tex](0.985)^{t}[/tex]<621859/691255
[tex](0.985)^{t}[/tex]<0.89960
[tex](0.985)^{t}[/tex]<[tex](0.985)^{7}[/tex]
By equating we find that t<7.
Hence if 691255 trees are present in the beginning then they will last for more than 7 years to reach 621859.

Find the Area of the figure below, composed of a parallelogram and two semicircles. Round to the nearest tenths place.
See
The picture please help test
Answer:
100.3 sqr. units
Step-by-step explanation:
Area of the composite figure = area of parallelogram + area of 2 semicircles
✔️Area of parallelogram = base * height
Base = 10
Height = 5
Area of parallelogram = 10*5 = 50 sqr. units
✔️Area of 2 semicircles = 2(½*πr²)
radius (r) = ½*8 = 4
Area of two semicircles = 2(½*π*4²)
Area of two semicircles = π*16 = 50.3 sqr.
✔️Area of composite figure = 50 + 50.3 = 100.3 sqr. units
What is the approximate volume of the cone?
Answer:
157 cm³
Step-by-step explanation:
Given
Radius (r) = 5 cm
height (h) = 6 cm
Volume of the cone (V) = ?
We have the formula
V = 1/3 *π*r²*h
V = 1/ 3 * 3.14 * 5² * 6
V = 157 cm³

Total surface area of a cube is 1014cm^2. It's volume will be :
a) 2197 cm^3
b) 2297 cm^3
c) 2179 cm^3
d) 2117 cm^3
plz answer...if you answer with explanation i will surely follow you and rate 5
Answer:
Option A (2197 cm³)
Step-by-step explanation:
For a cube with length of each side "a" , it's
Total Surface Area = 6a² Volume = a³_____________________________________________
According to the question ,
Total Surface Area = 1014 cm²
Let the length of each side of cube be 'a'.
Using the formula ,
[tex]6a^{2} =1014[/tex]
[tex]=> a^{2} =\frac{1014}{6} = 169[/tex]
[tex]=> a = \sqrt{169} = +13 \: or -13[/tex]
But length can't be negative . So , length of each side = 13 cm
∴ Volume of cube = 13³ = 2197 cm³
42 + 5t = 8t solve for t
Answer:
14
Step-by-step explanation:
do you want an explanaation?
btw, plz brainliestt :))
The value of t is 14
Given the algebraic equation:
[tex]42 + 5t = 8t\\[/tex]
To find the value of t in the algebraic equation given, we would apply the some of the laws of equalities or properties as follows:
[tex]42 + 5t - 5t = 8t - 5t[/tex] (subtraction property of equality)
[tex]42 = 3t\\\frac{42}{3} = \frac{3t}{3}[/tex] (division property of equality)
[tex]14 = t[/tex]
[tex]t = 14[/tex]
Therefore, the value of t is 14.

A fruit production company has three packaging facilities, each of which uses different-sized boxes as follows: 36 pieces per box, 28 pieces per box, and 20 pieces per box. Step 2 of 2 : Assuming each facility will receive the same amount of fruit, how many boxes will each facility package
Answer:
[tex]\frac{F}{36}, \frac{F}{28} ,\frac{F}{20}[/tex] respectively
Step-by-step explanation:
From the question we are told that
Facility A =36 pieces/box
Facility B =28 pieces/box
Facility C =20 pieces/box
Let the Fruit received be F
Generally the Facility A's number of boxes is mathematically given by
[tex]36 pieces=1 box[/tex]
Total Pieces=F
Therefore
Facility A's total amount of box = F/36
Generally the Facility B's number of boxes is mathematically given by
[tex]28pieces=1box[/tex]
Therefore
Facility B's total amount of box = F/28
Generally the Facility C's number of boxes is mathematically given by
[tex]20pieces=1box[/tex]
Therefore
Facility C's total amount of box = F/20
Therefore
Each Facility will make us of [tex]\frac{F}{36}, \frac{F}{28} ,\frac{F}{20}[/tex] respectively in packing there allocated Fruit.

Step-by-step explanation:
Find the cost of the book, by finding 15% of 32.80
32.80(0.15)
= 4.92
To find how much change he got back, subtract this from 5:

(−1/5)(x)+(−1/5)(−4)=−2(Distribute)
−1/5x+4/5=−2
Step 2: Subtract 4/5 from both sides.
−1/5x+4/5−4/5=−2−4/5
−1/5x=−14/5

M is directly proportional to r squared when r=2, m=14
Workout the value of r when M =224
Answer:
r = 8
Step-by-step explanation:
Given that M is directly proportional to r² then the equation relating them is
M = kr² ← k is the constant of proportionality
To find k use the condition when r = 2 , M = 14
k = [tex]\frac{m}{r^{2} }[/tex] =[tex]\frac{14}{4}[/tex] = [tex]\frac{7}{2}[/tex]
M = r² ← equation of proportion
When M = 224, then
224 =[tex]\frac{7}{2}[/tex]r² ← multiply both sides by 2
7r² = 448 ( divide both sides by 7 )
r² = 64 ( take the square root of both sides )
r = [tex]\sqrt{64}[/tex] = 8

The population of a town is growing uninhibited at a rate of 1% per year. How long would it take the population to double? Round to the nearest tenth.
a. 30.1 years
b. 69.3 years
c. 54.6 years
d. 10.2 years
Answer:
69.3 years
Step-by-step explanation:
use the equation 2=e^0.01t, then solve for t.
The required time at which the population of the town gets doubled is 69.3 years.
Given that,
The population of a town is growing uninhibited at a rate of 1% per year. how long would it take the population to double is to be determined.
The function which is in format f(x) =aˣ where a is constant and x is variable, the domain of this exponential function lies (-∞, ∞).
Here,
For exponential growth,
the equation is given as,
a = A (1 + 0.01)ˣ
For a = 2A, time x is to be determined,
2A = A (1.01)ˣ
1.01ˣ = 2
x = log2/log1.01
x = 69.3 years
Thus, the required time at which the population of the town gets doubled is 69.3 years.

Determine whether the variable is qualitative or quantitative. Explain your reasoning. The price of a new computer.
Answer:
The price of a new computer is quantitative.
Step-by-step explanation:
A variable can be classified as qualitative or quantitative.
Qualitative:
When the possible values of the variables are labels, for example, good or bad, yes or no,...
Quantitative:
When the possible values of the variables are numbers, for example 1, 2, 1000,....
In this question:
The price of a computer is a numeric value, so it is a quantitative variable.
"The price of a new computer" is a quantitative variable, because it can be measured and the values are numerical.
What are Qualitative and Quantitative Variables?Quantitative variables are variables whose values are numerical or measured. Example of a quantitative variable is number of students in a given class.Qualitative variables do not have numerical value or are not measurement variables. An example of a qualitative variable is eye color.Therefore, "the price of a new computer" is a quantitative variable, because it can be measured and the values are numerical.
