Evaluate 4^0×x^-5 when x=2 .
Answer:
1/32
Step-by-step explanation:
Anything to the power of 0 is 1.
1*x^-5 (negative power means the reciprocal)
1/2^5 = 1/32
1*1/32=1/32
When x = 2, the value of 4⁰ × x⁻⁵ is 0.03125.
To evaluate the expression 4⁰ × x⁻⁵ when x = 2, we'll substitute the value of x into the expression and perform the necessary calculations.
First, let's evaluate 4⁰. Any number raised to the power of 0 is equal to 1. Therefore, 4⁰ = 1.
Next, let's evaluate x⁻⁵ when x = 2. A negative exponent indicates the reciprocal of the base raised to the positive exponent. So, x⁻⁵ = 1 / x⁵.
Substituting x = 2, we have 1 / 2⁵.
Now, we can simplify the expression:
1 / 2⁵ = 1 / 32 = 0.03125
Therefore, when x = 2, the value of 4⁰ × x⁻⁵ is 0.03125.

Anna ran 10 meters, Bill ran 15 meters, and Chloe ran 20 meters. How many centimeters did the three people run?
Answer:
Anna: 1000cm
Bill: 1500
Chloe: 2000
convert m to cm
Answer:
4500 cm
Step-by-step explanation:
1 meter = 100 cm
10 meters = 1000 cm
15 meters = 1500 cm
20 meters = 2000 cm
1000 + 1500 + 2000 = 4500 cm

What is the value of p so that the expression 4(5 + n) is equivalent to 4(n + p) ?
Answer:
5
Step-by-step explanation:
4(5+n)=4(n+p)
20+4n=4n+4p
4p=20
p=20/4
p=5
Answer:
the value of p is 5
Step-by-step explanation:
the expression 4(5 + n) is equivalent to 4(n + p)
4(5+n)=4(n+p)
5+n=n+p
n+5=n+p
comparing each other
we get p=5

William and Ben are neighbors and found out they are born on the same day of the year.
William is 4 times older than Ben. But when you add their ages together and subtract 8 the
answer is 67. How old is Ben?
( you must create equations and solve by substitution to receive credit)
Answer:
(x+y)-8= 67y × 4 = x y= 15 Hence Ben is 15 years old 15×4= 60 years old Hence William is 60 years old Logic check: 60+15-8=67 75-8=67 67=67 I do quizzes and exams if your interested!!In a sample of 500 respondents, men account for 20% of all observations in the sample. What is the total number of females in the sample ?
A percentage is a way to describe a part of a whole. The total number of females in the sample are 400.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Given that In a sample of 500 respondents, men account for 20% of all observations in the sample. Therefore, if we deduct the number of male from the total number of respondents, then we can get the total number of women.
Now, the total number of females in the sample are:
Total number of females in the sample
= Total number of respondents - Total number of males in the sample
= 500 - 20% of total respondents
= 500 - 20% of 500
= 500 - 0.20(500)
= 500 - 100
= 400
Hence, the total number of females in the sample are 400.

Thomas puts $1100 into a savings account that earns 4.5% interest compounded monthly. How much money will he have in savings in 6 years?
If someone does a non-mathematical answer just for the points, I will report them. Thank you.
Answer:
$1440.23
Step-by-step explanation:
The formula for calculating future value of a sum compounded at specified times =
FV = PV x (1 + r/m)^nm
FV = Future value
P = Present value
R = interest rate
N = number of years
m = number of compounding
$1100 x ( 1 + 0.045 /12) ^12x6 = $1440.23

Ms. Anderson deposits $7,000 into a savings account that pays a simple interest of 2% per year. What is the total amount of money that will be in her account at the end of 3 years?
Answer:
$7420
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 2%/100 = 0.02 per year,
then, solving our equation
I = 7000 × 0.02 × 3 = 420
I = $ 420.00
The simple interest accumulated
on a principal of $ 7,000.00
at a rate of 2% per year
for 3 years is $ 420.00.
Solve
2x2 + 3x + 1 = 0
Answer:
it's false
Step-by-step explanation:
Answer:
x= -1 or x= -1/2
Step-by-step explanation:
x = -1, x = -1/2, Solve for x:
2 x^2 + 3 x + 1 = 0
The left hand side factors into a product with two terms:
(x + 1) (2 x + 1) = 0
Split into two equations:
x + 1 = 0 or 2 x + 1 = 0
Subtract 1 from both sides:
x = -1 or 2 x + 1 = 0
Subtract 1 from both sides:
x = -1 or 2 x = -1
Divide both sides by 2:
x = -1 or x = -1/2
