12π = 1/2πr²(4)r² = 9x = √9r = 3 ftAndy estimated that he would need 73 feet of lumber for a tree house project. He later found that the actual amount of lumber needed was 62 feet. What was the percent error of Andy's estimation?
Answer:
17.74%
Step-by-step explanation:
The formula for percent error is given as:
|Estimated value - Actual value|/Actual value × 100
From the above question:
Estimated value = 73 feet
Actual value = 62 feet
Hence,
Percent error = |73 - 62|/62 × 100
= 11/62 × 100
= 17.741935484%
Approximately , percent error = 17.74%
Therefore, the percent error of Andy's estimation is 17.74%

How do I solve these problem?
Answer:
- 199
Step-by-step explanation:
7.
a1 = 25
d = - 16
15th term is t15.
Formula : -
an = a + ( n - 1 )d
t15
= 25 + ( 15 - 1 ) - 16
= 25 + 14 ( - 16 )
= 25 + ( - 224 )
= 25 - 224
= - 199

The temperature in San Antonio, Texas is currently 77 degrees Fahrenheit and increasing by 3 degrees per hour. The current temperature in Mumbai, India is 92 degrees Fahrenheit and dropping by 2 degrees per hour. 1. When will the temperatures be the same? 2. What will that temperature be?
Answer:
1)3 2)86
Step-by-step explanation:
3h+77=SA AND 92-2h=MB
3h+77=92-2h
-77. = -77
3h= 15-2h
+2h=+2h
5h=15
H=3
From a barrel of colored marbles, you randomly select 1 blue 6 yellow 7 red 4 green and 6 purple marbles
Complete question :
From a barrel of colored marbles, you randomly select 1 blue 6 yellow 7 red 4 green and 6 purple marbles. Find the experimental probability of randomly selecting a marble that is NOT yellow.
Answer:
Step-by-step explanation:
Total number of marbles :
Blue = 1 ; yellow = 6 ; red = 7 ; green = 4 ; purple = 6
Total = (1 + 6 + 7 + 4 + 6) = 24 marbles
Probability of selecting marble that is not yellow :
Number of marbles that aren't yellow / total number of marbles
Marbles that aren't yellow = 24 - 6 = 18
P(selecting a marble that isn't yellow) = 18 / 24 = 3/4
ect the correct answer.
Which of the following graphs represents the equation below?
Which ordered pairs are solutions to y = x + 1?
A (0,1),(1,2), (2,3)
B (0, -1), (2, -1), (3,-2)
C (0,1),(1,2), (2, 4)
D (0,1),(2, 1), (3, 1)
Answer:
A. ( 0, 1 ), ( 1, 2 ), ( 2, 3 )
Step-by-step explanation:
( x, y ) = ( 0, 1 )
Here,
x = 0
y = 1
y = x + 1
1 = 0 + 1
1 = 1
( x, y ) = ( 1, 2 )
Here,
x = 1
y = 2
y = x + 1
2 = 1 + 1
2 = 2
( x, y ) = ( 2, 3 )
Here,
x = 2
y = 3
y = x + 1
3 = 2 + 1
3 = 3
In 1990, the population of the U.S. was about 250 million and was growing exponentially
at a rate of about 1% per year. At this rate, in what year will the population have
doubled?
a. 2080
b. 2070
c. 2060
d. 2050
Answer:
The correct answer is C.
Step-by-step explanation:
Giving the following information:
Present Value (PV)= 250 million
Future Value (FV)= 500 million
Growth rate (g)= 1% per year
First, we need to calculate the number of years required for the population to double:
n= ln(FV/PV) / ln(1+g)
n= ln(500/250) / ln(1.01)
n= 69.66 = 70 years
It will take 70 years for the population to double.

Answer:
B. y = 85x
Step-by-step explanation:
First, find the rate of change of the graph:
Rate of change = change in y/change in x
Using two points (0, 0) and (4, 300),
Rate of change (m) = (300 - 0)/(4 - 0) = 300/4
Rate of change (m) = 75
Compare this with the rate of change of the given equations in the options.
✔️Option A: y = 65x + 100
The rate of change of this equation is 65, which is less than the rate of change of the given graph (75)
✔️Option B: y = 85x
The rate of change of this equation is 85, which is greater than the rate of change of the given graph (75)
✔️Option B: y = 50x + 150
The rate of change of this equation is 50, which is less than the rate of change of the given graph (75)
✅Therefore, the equation that has a greater rate of change than the one shown in the graph is y = 85x

how to solve x^2-4x=-12
x = 6 and x = -2
Step-by-step explanation:
Put the 12 to the other side
x^2 - 4x - 12 = 0
Now factor this out:
(x - 6)(x + 2) = 0
Therefore, the roots of this equation are
x = 6 and x = -2
