The snow is now 52 inches deep. If this was a 77% decrease, what was the initial depth? What equation can help you find this?
Answers
Answer:
The required equation is:
0.23x = 52
Hence, option A is true.
Step-by-step explanation:
Given
Let 'x' be the initial depth
The snow is now 52 inches deep and it is a 77% decrease.
Let the initial 'x' depth be represented as 100%.
x → 100%
Given the current 52 inches is a 77% decrease. So, we need to decrease the 77/100 or 0.77 from the initial depth, so
[100% - 77%] of x = 52
[100/100 - 77/100] × x = 52
[1 - 0.77] × x = 52
0.23x = 52
Therefore, the required equation is:
0.23x = 52
Hence, option A is true.

Elwood invested $5,000 in a money market account and has been tracking its progress. He found that after 3 years, the account held $7,100 and after 8 years, the account held $10,350. Use this information to complete the statements. Over the first 3 years, the value of the account increased at ___ over the last 5 years. Over the entire 8 years, the value of the account increased at an average rate of approximately $___ annually.
Answers
Answer:
Given:
Principal= $5,000
After 3 years, Amount= $7,100
After 8 years, Amount= $10,350
Step-by-step explanation:
Interest after 3 years= $7,100- $5,000
=$2,100
Interest in last 5 years= $10,350- $7,100
=$ 3,250
Difference between first 3 years and last 5 years= $3,250- $2,100
=$1,150
Amount= Principal*[tex](1+r/100)^{t}[/tex]
10,350=5000[tex](1+r/100)^{8}[/tex]
[tex]\frac{10350}{5000}[/tex]=[tex](1+r/100)^{8}[/tex]
2.07=[tex](1+r/100)^{8}[/tex]
[tex]2.07^{1/8}[/tex]=1+[tex]\frac{r}{100}[/tex]
1.095-1=[tex]\frac{r}{100}[/tex]
0.095*100=r
r=9.5%
Average rate=[tex]\frac{5000*9.5*1}{100}[/tex]
=$475
Answer:
drop down 1 a slower rate per year
drop down 2 670
Step-by-step explanation:
as in three years you get $7100
you take that and subtract it by your starting amount (5000)
7100-5000= 2100
then divide 2100 by the number of years (3)
to get your annual rate of 700$
then you take the 8 year total and subtract it from your 3 year total
10350-7100= 3250
Then divide that by 5 because that how many years it has been
to get the annual rate of 650
making the 5 year rate slower.
The to find the average rate over all 8 year you take 10350 and subtract it from your starting number 5000
10350-5000= 5350
then take 5350 and divide it by the number of years (8)
you then get you average rate of 668.75
668.75=670

Submit
Answers
Answer:
c= -20h + 90
Step-by-step explanation:
The equation that describes the relationship between c and h is:
[tex]c= -20h + 90[/tex]
We have the graph that shows the amount of charge left on computer, c, after h hours.
Let us consider two points (h, c) on the graph
(0,90) and (4.5, 0)
Now the equation of the line passing through two points
[tex]\frac{c-90}{h-0} =\frac{0-90}{4.5-0} \\c-90=-20h\\c=-20h+90[/tex]
So, the equation that describes the relationship between c and h is:
[tex]c= -20h + 90[/tex]

Answer:
x = 27
Step-by-step explanation:
∠ ABD and ∠ BDE are alternate angles and are congruent, then
∠ BDE = 72°
∠ ADB + ∠ BDE + ∠ EDF = 180° ( sum of angles on a straight line ), that is
2x + 72 + 2x = 180
4x + 72 = 180 ( subtract 72 from both sides )
4x = 108 ( divide both sides by 4 )
x = 27

if x=z+8 where z varies inversely as y and z=2 when y=3 find relation between y and x?
Answers
Answer:
y = 6/(x - 8).
Step-by-step explanation:
z = k/y where k is a constant
2 = k/3
k = 6.
So z = 6/y
and x = 6/y + 8
Multiply through by y:
xy = 6 + 8y
xy - 8y = 6
y(x - 8) = 6
y = 6/(x - 8)

Step-by-step explanation:
i) reduce the fraction with 4[tex] \frac{28}{36} = \frac{14}{y} [/tex]
[tex] \frac{28 \div 4}{36 \div 4} = \frac{14}{y} [/tex]

The independent variable is n (number of months) and the dependent variable is C ( total cost)
Step-by-step explanation:
Let the total cost of the fitness center = C
Given fixed cost = $100
given cost per month = $40
let number of month = n
The total cost of the fitness center in a given 'n' month is calculated as;
C = 100 + 40n
From the above equation;
the independent variable is n (number of months) and
the dependent variable is C ( total cost)
C = 100 + 40n The independent variable is n (number of months) and the dependent variable is C ( total cost)
