Answer:
There are 64 chickens
Step-by-step explanation:
60% of the animals were not chickens so I found 60% of 160 which is 96, and then I subtracted 96 from 160 and got 64
Please mark brainlest for my overcomplicated description of math
Answer:
16 horses
32 cows
48 goats
64 chickens
Step-by-step explanation:
total animals = 160
⇒ 10% of animals = 160/10 = 16
⇒ 20% = 16 x 2 = 32
⇒ 30% = 16 x 3 = 48
16 horses
32 cows
48 goats
chickens = 160 - 16 - 32 - 48 = 64

Answer:
y = 1000·1.20^x
Step-by-step explanation:
The form of an exponential function is ...
y = a·b^x
where 'a' is the initial value (y-intercept), and 'b' is the common ratio (growth factor).
The growth factor is related to the growth rate by ...
growth factor = 1 + growth rate
For a growth rate of 20%, the growth factor is ...
growth factor = 1 +20% = 1.20
__
The problem statement tells you the initial value is $1000, so your exponential function is ...
y = 1000·1.20^x . . . . . x is the number of years after the current year; y is the watch value in dollars
A swimming pool is 20.6 m long, 8.5 m wide, and has an average water depth of 1.7 m. Find the volume of water needed to fill the pool.
Answer:
Thus Volume of pool is [tex]297.67m^{3}[/tex]
GIVEN: A swimming pool 20.6 m long 8.5 m wide and height 1.7 m
TO FIND: Volume of water needed to fill it.
SOLUTION:
Length = 20.6 m
Width = 8.5 m
Height = 1.7 m
Volume = L × B × H
→ [tex]1.7\times20.6\times8.5[/tex]
→ [tex]297.67m^{3}[/tex]
Thus volume of pool is [tex]297.67m^{3}[/tex]

The point-slope form of a line that has a slope of –2 and passes through point (5, –2) is shown below.
y + 2 = –2 (x–5)
What is the equation in slope-intercept form?
Answer:
y = -2x + 8
Step-by-step explanation:
Solve for y
y + 2 = -2(x - 5)
y + 2 = -2x + 10
y = -2x + 8
y = -2x + 8
Slope-int. form is written as y=mx+b
m is your slope and b is you y intercept
You first will evaluate the -2(x-5) to get:
-2x + 10
Then you'll subtract 2 from each side to get the y alone:
y = -2x + 8

The rectangular model is made up of squares. Each square is of equal size.
What percentage of the model is shaded?
The percentage of the model is shaded is 45% if the total number of square is 80 option (H) is correct.
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.
Total number of squares = 10×8 = 80
Total number of squares shaded = 36
Percentage of the model is shaded = (36/80)×100
= 0.45×100
= 45%
Thus, the percentage of the model is shaded is 45% if the total number of square is 80 option (H) is correct.

How do you find derivative of a function with two variables.
A function z=f(x,y) has two partial derivatives and y. These derivatives correspond to each of the independent variables and can be interpreted as instantaneous rates of change (that is, as slopes of a tangent line). Similarly, ∂z/∂y represents the slope of the tangent line parallel to the y-axis.

17) The frequency table shows the number of miles lake drove over a 12 month period. Using the frequency table, find the average number of miles he drove per month. (Round to the nearest tenth.)
A) 1350.0
B) 1358.0
91358.3
D) 1358.4
E) 1359.0
Frequency tables are used to represent datasets and their frequencies
The average number of miles he drove per month is 1358.3 miles
How to determine the average number of milesFrom the frequency table, the total number of miles travelled in a year is:
Total = 16300 miles
There are 12 months in a year.
So, the average number of miles is:
[tex]Average = \frac{16300}{12}[/tex]
Divide
[tex]Average = 1358.3[/tex]
Hence, the average number of miles he drove per month is 1358.3 miles

because do you see how v is lined 2 I don't remember if you times or divide .I'm going to go with times.
So what is 2 x 10 since V=10
2 x 10=20
Then we are going to divide so what is 20 divided by 5 since e=5
20 divided by 5=4
Next our last step what is 4 + 3=7 and there's are answer.
The answer is divide then this would be the answer.
so V(10) divided by 2=5 divided by e(5) =1 + 3=4

Ronisha invests $5000 in an account that earns 2.3% annual simple interest. After 3 years, Ronisha invests the interest earned in a second account. This account earns 3.2% annual interest. Ronisha leaves the money in this account until she has earned $55.20 in interest. Ronisha does not deposit or withdraw any money from the accounts. How long does Ronisha invest money into the second account?
[tex]~~~~~~ \textit{Simple Interest Earned} \\\\ I = Prt\qquad \begin{cases} I=\textit{interest earned}\\ P=\textit{original amount deposited}\dotfill & \$5000\\ r=rate\to 2.3\%\to \frac{2.3}{100}\dotfill &0.023\\ t=years\dotfill &3 \end{cases} \\\\\\ I = (5000)(0.023)(3)\implies I=345[/tex]
so then she grabs those 345 earned and puts it in the second account earning 3.2%, how long till that yields 55.20 bucks in interest alone?

in this case, 3/4 is correct because it is 3 of 4 shaded.

Hii! Its your friend Nat! :)
Known: 3/4 of the model is shaded, we are multiplying.
The model repersents 3/4
This is because only 3 out of 4 pieces are shaded in.
If all pieces were shaded it would be 4/4 or 1 whole.
1/3 x 3/4 is 3/12
3/12 simplifed is 1/4

Ralph earns $72,000 annually as an architect and is paid semimonthly. Alice also earns $72,000 but she is paid biweekly.
a. How many more checks does Alice receive in a year when compared to Ralph?
b. What is the difference between Ralph's semimonthly salary and Alice's biweekly salary? Round to the nearest cent.
Step-by-step explanation:
there are 12 months in a year, and therefore 2×12 = 24 "half-months" and therefore semimonthly payments.
that means each paycheck is
72,000 / 24 = $3,000
there are 52 weeks per year.
that means they're are 52/2 = 26 biweekly periods and therefore payments.
each paycheck is therefore
72,000 / 26 = $2,769.23
so, Alice receives 2 more paychecks (26 to 24) in a year.
the difference between the 2 types of payment is
3000 - 2769.23 = $230.77
If x varies inversely as t, and x = 8 when t = 6, find t when x = 12-
=
Answer:
t = 4
Step-by-step explanation:
given x varies inversely as t , then the equation relating them is
x = [tex]\frac{k}{t}[/tex] ← k is the constant of variation
To find k use the condition x = 8 when t = 6 , then
8 = [tex]\frac{k}{6}[/tex] ( multiply both sides by 6 )
48 = k
x = [tex]\frac{48}{t}[/tex] ← equation of variation
when x = 12 , then
12 = [tex]\frac{48}{t}[/tex] ( multiply both sides by t )
12t = 48 ( divide both sides by 12 )
t = 4

You borrowed $200 from a friend. He asked you to pay $2 each month for 2 years.
A. What is the total amount you pay after 2 years?
B. What is the annual rate of interest your friend is charging you?
Answer:
48$ and -110.842%
Step-by-step explanation:
A=48$
It=48$ because your paying 2$ for 2 years so 1 year=12 months so 2$=1 month so in 12 months he gets 24$ and then for another year he get's another 24$
24 + 24=48$.
B= -110.842%
it= -110.842.

HELP WITH NUMBER 13 please
Answer: QE = 10
Step-by-step explanation: To solve this problem, it's important to understand that the diagonals of a parallelogram bisect each other.
This means that E is the midpoint of diagonal SQ.
So we can setup the equation x² + 9x = 4x + 6.
To solve this polynomial equation, set it equal to zero first.
So we have x² + 5x - 6 = 0 and we get (x + 6)(x - 1) = 0
when we factor the left side of the equation.
So this means that x = -6 or x = 1.
However, -6 will give us a negative length when we plug it in
to find QE so this will not work.
However, plugging 1 in will give us 10 as a length so QE = 10.

How do you find the equation, domain, and range using a graph?
Answer/Step-by-step explanation:
For the one on the left, the domain is (-∞,-1)∪[0,0]∪(1,3]
Remember that the domain is what values x are. If the dot is solid, use a bracket, if it is empty, use parentheses.
The range is [-3,-3]∪[-1,-1]∪(2,4]
The equation is a piece-wise function.
When x>-1 f(x)=-3
When x=0 f(x)=-1
When 1<x≤2 f(x)=2x
