Step-by-step explanation:
There are 2 different unit rates here:
The increase of the tree's height per year The increase of the tree's trunk per yearRate of tree's height per year
= 33m / 150 years = 0.22m per year.
Rate of tree's trunk per year
= 3m / 150 years = 0.02m per year.
The difference of two numbers is 3, and the sum of three times the larger one and twice the smaller one is 19. Find the two numbers.
Answer:
small number = 28/5 or 5 3/5
larger number = 13/5 or 2 3/5
Step-by-step explanation:
x = small number
y = large number
set up a system of equations:
x - y = 3
3y + 2x = 19
using substitution method:
let x = 3 + y
3y + 2(3 + y) = 19
3y + 6 + 2y = 19
5y + 6 = 19
5y = 13
y = 13/5
solve for x:
x - 13/5 = 3
x = 15/5 + 13/5
x = 28/5

I don’t understand help plzz
Answer:
Slope/m=1/2, y-intercept=-4
Step-by-step explanation:
Y=mx+b is slope-intercept form. So in the equation y=1/2x-4, m stands for the slope, and in the equation 1/2 is in the place of m. B stands for the y-intercept, and in its place is -4.

A gardening center is planting trees for sale. Until the trees are fully grown, employees need to put rope
around the square section where the trees are planted so that customers do not disturb them. The area of the
soction is 132.25 ft? How much rope will the gardening center need to purchase to surround the section where
the trees are being planted?
Answer: 46ft
Step-by-step explanation:
You take the area and find it's square root then multiply it by how many sides there are to the figure in this case it is 4 sides so you multiply it by 4 getting 46

Sally has a budget for school stationery of $37, but has already spent $22.72 on books and folders. Let p represent the amount that Sally can spend on other stationery. Write an inequality that shows how much she can spend on other stationery, and solve for p.
Answer:
[tex]p\le 14.28[/tex]
Step-by-step explanation:
Total budget for school stationery = $37
She has already spent $22.72 on books and folders.
Left amount = $37 - $22.72
= $14.28
Let p represent the amount that Sally can spend on other stationery. It implies that "p" must be less than or equal to $14.28 .
Hence, the required inequality is :
[tex]p\le 14.28[/tex]

The perimeter of a rectangular lot of land is 448 A. This includes an easement of x feet of uniform width Inside the lot on which no building can be done . If the buildable area is 140 ft by 64 determine the width of the easement.
Answer:
[tex]5\ \text{ft}[/tex]
Step-by-step explanation:
Perimeter of rectangular lot = [tex]448\ \text{ft}[/tex]
The width of the easement is [tex]x\ \text{ft}[/tex]
Buildable area 140 ft by 64 ft
[tex]2(140+2x)+2(64+2x)=448\\\Rightarrow 140+2x+64+2x=\dfrac{448}{2}\\\Rightarrow 204+4x=224\\\Rightarrow x=\dfrac{224-204}{4}\\\Rightarrow x=5\ \text{ft}[/tex]
The width of the easement is [tex]5\ \text{ft}[/tex].
What is the value of x in the equation 25x2 = 16. A. 5/4. B. 4. C. 4/5. D. 16/25
Answer:
x = ⅘
Step-by-step explanation:
For clarity, exponents should be marked with a ^. 25x² can be written as 25x^2.
25x² = 16
divide both sides by the 25
x² = 16/25
take the square root of both sides
x = √(16/25) = √16/√25 = 4/5
Mike and Andy are each reading the same book mike reads 2\4 of the book on Tuesday and 1\3 of the book on Wednesday Andy reads 1\2 of the book on Tuesday and 1\5 of the book on Wednesday Andy says that all together he reads more of the book on Tuesday and Wensday then mike
Answer:
Andy's claim is incorrect
Step-by-step explanation:
Given
Mike:
[tex]Tuesday = \frac{2}{4}[/tex]
[tex]Wednesday = \frac{1}{3}[/tex]
Andy:
[tex]Tuesday = \frac{1}{2}[/tex]
[tex]Wednesday = \frac{1}{5}[/tex]
Required
Is Andy correct?
First, we need to calculate the fraction of book read by Mike.
[tex]Mike = \frac{2}{4} + \frac{1}{3}[/tex]
Take LCM
[tex]Mike = \frac{6+4}{12}[/tex]
[tex]Mike = \frac{10}{12}[/tex]
Convert to decimal
[tex]Mike = 0.833\\[/tex]
Next, we perform the same calcuation for Andy
[tex]Andy = \frac{1}{2} + \frac{1}{5}[/tex]
Take LCM
[tex]Andy = \frac{5+2}{10}[/tex]
[tex]Andy = \frac{7}{10}[/tex]
Convert to decimal
[tex]Andy = 0.70[/tex]
Andy's claim that he read more of the book is incorrect because 0.833 (for Mike) is greater than 0.70 (for Andy)

You have a bag with 12 jelly beans in it 4 red 2 black 5 yellow and 1 pink what is the probability of not picking a black one
Answer:
[tex]\boxed {\boxed {\sf \frac{5}{6} \ or \ 0.833}}[/tex]
Step-by-step explanation:
Probability can be found by dividing the favorable outcomes by the total outcomes.
[tex]P=\frac{favorable \ outcomes}{total \ outcomes}[/tex]
In this problem, a favorable outcome is not picking a black jelly bean. The total outcomes is the total number of jelly beans.
[tex]P( \ not \ black \ jelly \ bean)=\frac{not \ black \ jelly \ beans}{all \ jelly \ beans}[/tex]
There are 10 jelly beans that are not black (4 red+5 yellow + 1 pink =10) There are 12 total jelly beans (4 red+ 2 black+ 5 yellow + 1 pink= 12)[tex]P( not \ black \ jelly \ bean )=\frac{10}{12}[/tex]
This fraction can be reduced. Both the numerator and denominator can be divided by 2.
[tex]P(not \ black \ jelly \ bean)=\frac{10/2}{12/2}[/tex]
[tex]P(not \ black \ jelly \ bean)=\frac{5}{6}[/tex]
Probabilty can also be written as a decimal.
[tex]P(not \ black \ jelly \ bean)=0.833[/tex]
The probabilty of not picking a black jelly bean is 5/6 or 0.833

Find the smallest non-zero whole number which can be multiples by 112 to give a cube number
Answer is : Step-by-step explanation:
Given Find the smallest non-zero whole number which can be multiplied by 112 to give a square number and a cube number.
So cube root of 21,952 will be 28.
Reference link will be.

hope it helps
Answer:
176.
Step-by-step explanation:
112 = 2*2*2*2*7
For a cube number there must be 3 or a multiple of 3 of each factor.
So we multiply by 2*2 and 7 * 7 to give 2^6 * 7^3 which is 21952.
The answer is 4*49
= 176.
Checking that 21952 is a cube:
