[tex]V_{sphere} = \frac{4}{3} \times \pi {r}^{3} \\ \\ V_{sphere} = \frac{4}{3} \times \pi {(2)}^{3} \\ \\ V_{sphere} = \frac{4}{3} \times \pi \times 8 \\ \\ V_{sphere} = \frac{32 \times 3.14}{3} \\ \\ V_{sphere} = \frac{100.48}{3} \\ \\ V_{sphere} = 33.4933333\\ \\ V_{sphere} \approx 33.49\: units^3 [/tex]
A stack of 5 pennies weighs 0.0075 kilograms. One kilogram is approximately 2.2 pounds.
How many pounds, rounded to the nearest hundredth, does a stack of 100 pennies weigh?
Answer:
20 stacks of 5 pennies weight 0.33 pounds
Step-by-step explanation:
First, we need to calculate the weight in kilograms of 20 stacks of 5 pennies:
20 stacks= 0.0075*20
20 stacks= 0.15 kg
Now, we can determine the weight in pounds:
1kg = 2.2 pounds
0.15kg = ?
Weight in pounds= (0.15*2.2)/1
Weight in pounds= 0.33 pounds
20 stacks of 5 pennies weight 0.33 pounds

PLEASE HELP ME ANSWER THIS!!!
Answer:
For a function f(x), a vertical stretch of scale factor K is written as:
g(x) = k*f(x)
And for a function f(x), a vertical translation of N units is written as:
g(x) = f(x) + N
If N is positive, the translation is up
if N is negative, the translation is down.
1) We have the function:
y = f(x) = 5^(x - 2)
A vertical stretch of factor 3 will be:
y = g(x) = 3*f(x) = 3*(5)^(x - 2)
2) We have the function:
y = f(x) = 7.2^x
A translation up of 8 units will be written as:
y = g(x) = f(x) + 8 = 7.2^x + 8

0
Answer:
Step-by-step explanation:
hello : solutions in R
cosxcos((x+π)/4) =0
means : cosx = 0 or cos((x+π)/4) =0
1) cosx = 0 means : x = π/2+kπ k in Z
2) cos((x+π)/4) =0 means : (x+π)/4 = π/2+kπ .......continu calculate : x

Men and women aren’t equal evaluate this statement. Give some religous scriptures
Answer:
Indeed, men and women are not the same. They have structural differences in their genetic makeup that make them different and compatible with each other. In addition, they have differences in character, behavior, strength and even emotional sensitivity.
Even the scriptures themselves speak of differences between the two: according to the book of Genesis, the woman was created from the rib of Adam, the first man on earth. With this, the woman, theoretically, has one more rib than the man.

lucy works for 37 hours per week. her weekly wage is £303.40. she receives a pay increase of 25p per hour. work out her new weekly wage
Answer:
312.65
Step-by-step explanation:
The new weekly wage is $312.65 if the Lucy works for 37 hours per week. Her weekly wage is £303.40.
What is linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
Lucy works for 37 hours per week.
Weekly wage = $303.40
Per hour wage = 303.40/37 = $8.2 per hour
1 dollar = 100 penny(p)
25p = $0.25
New wage per hour = 8.2 + 0.25 = $8.45
Total wage = 8.45×37 = $312.65
Thus, the new weekly wage is $312.65 if the Lucy works for 37 hours per week. Her weekly wage is £303.40.

Answer:
3, 50, 2
Step-by-step explanation:
By multiplying all terms by 5, we are trying to remove the fraction on the left hand side. On the right hand side of the equation, expand the bracket by multiplying 5 to each term in the bracket.
3(n +25)= 5(10) +5([tex] \frac{2}{5} n[/tex])
3(n +25)= 50 +2n
To find the value of n, expand the bracket on the left hand side:
3(n) +3(25)= 50 +2n
3n +75= 50 +2n
Bring all n terms to one side, constants to the other:
3n -2n= 50 -75
n= -25
