A diagram showing a neighborhood park is plotted on the coordinate plane. Each unit on the coordinate plane represents 1 yard. Find the PERIMETER and the AREA.
Answers
Answer:
Step-by-step explanation
The length of the left sloping line
= √ (5^2 + 7^2) = √74.
The right sloping line
= √(5^2 + 5^2) = √50.
So the perimeter:
= √74 + √50 + 2 + 2 * 4 + 14
= 39.67 to nearest hundreth.
Area = 1/2 * 5 * 7 + 2*5 + 1/2 * 5 * 5 + 4*14
= 96.

A company has recently been hiring new employees. today the company has 35% more employees than it did a year ago. if there are currently 37,800employees, how many employees did the company have a year ago?
Answers
Answer:
28000 employeeStep-by-step explanation:
let x be the number of the employees of the company ,a year ago.
the statement “today ,the company has 35% more employees than it did a year ago”
means
[tex]x+\frac{35}{100} x=37800[/tex]
[tex]\Longrightarrow x\times \left( \frac{100}{100} +\frac{35}{100} \right) =37800[/tex]
[tex]\Longrightarrow x\times \left( \frac{135}{100} \right) =37800[/tex]
[tex]\Longrightarrow x=\frac{37800\times 100}{135}[/tex]
[tex]\Longrightarrow x =28000[/tex]

Find the slant height of a cone given that its lateral area is 144π cm2 and the diameter is 9 cm. diameter 9 cm 2 cm 32 cm 4 cm 18 cm
Answers
Answer:
32 cm.
Step-by-step explanation:
Lateral area = πrL
where r = radius of the base and L = the slant height.
The radius = 1/2 * diameter = 4.5 cm.
So from the values given:
144π = π* 4.5 * L
4.5L = 144
L = 144/4.5
= 32 cm.

Can someone please help? the value of a plot of land increases 8% every year. the value is $350000 now, and the owner wants to sell it when the value is at least $570000. shanna writes an exponential function of the form, v(t)=a*b^t, to model the value,v, of the land in t years. i need to know what the value of b is and the domain
Answers
The value of b in the exponential function which is formed by Shanna for the price of land is 8% or 0.08.
What is percentage increase ?Percentage increase is the amount added to the initial value in the percentage part.
The value of a plot of land which is increases 8% every year has the current value of $350000.
The final value owner wants is $570000. Shanna writes an exponential function of the form, to model the value,v, of the land in t years as,
[tex]v(t)=a\times b^t[/tex]
Here, in this exponential function the value of a is fixed or initial term which is $350000 and the value of b is the constant term which is change factor. Here, the value of b is 8%.
b=8%
b=8/100
b=0.08
Thus, the value of b in the exponential function which is formed by Shanna for the price of land is 8% or 0.08.

Step-by-step explanation:
If the minus sign after the x was on purpose or if you accidentally put the addition sign after the minus or the other way around basically I have no idea if the solution I provided is correct so here's the solution to both possible equations you might have meant to type instead (and if this was intentional then awesome):
1. 2x - 6x = -3 and 2. 2x + 6x = -3
Let's do 1. first!
[tex]2x-6x=-3[/tex]

[tex]-4x=-3[/tex]
Divide each side by -4
[tex]x=\frac{-3}{-4}[/tex]
And as you know, two negatives equal/make a positive
[tex]x=\frac{3}{4}[/tex] or [tex]x=0.75[/tex]
Now! Let's solve for 2.
[tex]2x+6x=-3[/tex]

One year, the population of a city was 73,000. Several years later it was 85,410. Find the percentage decrease
Answers
The percentage decrease is 14.52% if, one year, the population of a city was 73,000. Several years later, it was 85,410.
What is the percentage?It is defined as the ratio of two numbers expressed in the fraction of 100 parts. It is the measure to compare two data, the % sign is used to express the percentage.
The initial population = 85410
The final population = 73000
The decrease = (85410 - 73000)/85410 = 0.1452
The percentage decrease = 0.1452×100 = 14.52%
Thus, the percentage decrease is 14.52% if one year, the population of a city was 73,000. Several years later, it was 85,410.

Step-by-step explanation:
Ice sheets have one particularly special property. They allow us to go back in time and to sample accumulation, air temperature and air chemistry from another time[1]. Ice core records allow us to generate continuous reconstructions of past climate, going back at least 800,000 years[2].
Ice coring has been around since the 1950s. Ice cores have been drilled in ice sheets worldwide, but notably in Greenland[3] and Antarctica[4, 5]. High rates of snow accumulation provide excellent time resolution, and bubbles in the ice core preserve actual samples of the world’s ancient atmosphere[6].

The answer is "Yes". There is indeed a property that we can use, and it's called "The distributive property".
[tex]\ast[/tex] As the name implies, we distribute a number, variable, or a combination of the two.
We distribute by multiplying this number or variable or whatever we need to distribute by the expression inside the parentheses, as follows :

How long would it take 10 workers to seed 90 acres?
Answers
Answer:
27 hours
Step-by-step explanation:
We are given the information that it takes 6 hours for 20 workers to seed 40 acres. This means that with 20 workers the rate is 40 acres in 6 hours, or 40/6 = 6.67 acres per hour. When we only have 10 workers, we only have half as many people, therefore the rate will be twice as slow, so with 10 workers, the rate is 6.67/2 = 3.34 acres/hour.
To find how long it takes to seed 90 acres we just need to divide 90 by the rate. 90/3.34 = 27 hours.
