Answer:
volume = 10.2 in³
Step-by-step explanation:
r = 2.7/2 = 1.35
volume = 4/3πr³ = 4/3(3.14)(1.35³) = 10.2 in³

Step-by-step explanation:
At the tasty bakery, cupcakes cost fifty cents each.Doughnuts cost a dollar twenty five.How much more do two doughnuts cost than two cupcakes?
Answer:
$1.50
Step-by-step explanation:
The computation is shown below:
Given that
The cost of each cupcakes be 0.50 cents
And, the cost of doughnuts be $25
So for two doughnuts the cost would be 2.50
And, for two cupcakes, the cost would be 0.50 × 2 = 1
So, the more amount would be
= 2.50 - 1
= $1.50
Hence, the same would be considered and relevant too
condense this logarithm to a single logarithm
6log 5u
Answer:
log_5(u^6)
Step-by-step explanation:
According to log rules, log_a(b^n) = nlog_a(b), reversing this we get that log_5(u^6) is what you are looking for.

It takes Bobby 12 hours longer to build a robot than it takes Alex. Together, they can build the Robot in 8 hours. How long does it take Bobby to build the robot by himself?
Answer:
24 hours
Step-by-step explanation:
The computation of the number of hours taken by Bobby to build the robot by himself is shown below:
Given that
Bobby could take 12 hours
Together they could build in 8 hours
So based on the above information
the number of hours taken by Bobby to build the robot by himself is
Let us assume the above line be x
So,
[tex]\frac{1}{8}-\frac{1}{12} = \frac{1}{x} \\\\\frac{6 - 4}{48} = \frac{1}{x} \\\\\frac{2}{48} = \frac{1}{x} \\\\x = \frac{48}{2}[/tex]
x = 24 hours
Please help it's for trig
Answer:
-4
Step-by-step explanation:
Given the expression
h(x) = -x^2 +4x
h(-2) = (-2)^2 + 4(-2)
h(-2) = 4 + (-8)
h(-2) = 4 - 8
h(2) = -4
Hence the value of the function when x = -2 is -4

Step-by-step explanation:
Lee buys a computer and a printer for $2,028 The printer costs 30% the price of the computer. What is the price of the computer?
Answer: $1,560
Step-by-step explanation:
Assume the computer's price is x.
This means that expressing the printer in terms of x would be:
= 30% * x
= 0.3x
These two put together represent the cost of $2,028
Expression is:
x + 0.3x = 2,028
1.3x = 2,028
x = 2,028/ 1.3
x = $1,560
Computer was $1,560
Printer was therefore:
= 1,560 * 30%
= $468

Question 1:
A trader made a profit of 20% on a radio which he sold for N144 .Calculate the cost price of the radio .
Question 2:
A motor dealer sold a car at a loss of 20% by selling it at N10,000 . Find the cost price.
Note :
Cost price formula :
[tex]C.P = S.P-P \\ or S.P+L[/tex]
Selling Price Formula :
[tex]S.P = C.P + P \\ or C.P - Loss[/tex]
Profit Percentage ( P% ) formula :
[tex] P \% = P/C.P × 100 \\ l \% = l/C.P × 100[/tex]
Answer:
Question 1
Given
SP = 144P = 20%CP = xUse formula and solve for x:
SP = CP + P144 = x + (20% of x)144 = x + 0.2x144 = 1.2xx = 144/1.2x = 120Cost price is N 120
Question 2
Given
SP = 1000P = -20% (negative because of loss)CP = xUse formula and solve for x:
SP = CP + P10000 = x - (20% of x)10000 = x - 0.2x10000 = 0.8xx = 10000/0.8x = 12500Cost is N 12500
What is the area of this shape?
Answer:
12mm (triangle)
165mm (whole shape)
Step-by-step explanation:
The triangle is 6 x 4 = 24 ÷ 2= 12
(divide by 2 because its a teiangle)
2nd shape is 10 x 8 = 80
3rd shape is 6 x 12 = 72
72 + 80 + 12 = 165mm

The locker combination consists of 4, single digits ranging 0-9. How many possible combinations are there?
Answer:
10000 possible combinations
Step-by-step explanation:
Number of digits = 4
Range of values of each digit = 0 - 9
Number of digits in range = 10
Hence, each digit could be = (1 - 10)
1st digit = 10
2nd digit = 10
3rd digit = 10
4th digit = 10
Total possible combination :
10 * 10 * 10 * 10 = 10000 possible combinations

Answer:
21.5sqft
Step-by-step explanation:
The area of the square is 10ft*10ft = 100sqft
The area of the circle is 5ft*5ft*pi = 25pi sqft
We're supposed to use 3.14 for pi, so the circle is around 25*3.14 sqft = 78.5sq ft
The area left over is 100sqft - 78.5sqft = 21.5sqft
Answer:
21.5 sq. feet

3/2x -1=5
Answer:
4
Step-by-step explanation:
3/2x -1 = 5
then
3/2x = 5+1
then
3/2x = 6
then
x = 6 / (3/2)
then
x = 6 *2/3
then
x = 4
A psychologist takes an SRS of 404040 people in their twenties and 606060 people in their fifties and surveys them about their anxieties. Suppose that 48\%48%48, percent of people in their twenties and 28\%28%28, percent of people in their fifties have anxiety about flying. The psychologist will then look at the difference (\text{20's}-\text{50's})(20’s−50’s)left parenthesis, start text, 20, apostrophe, s, end text, minus, start text, 50, apostrophe, s, end text, right parenthesis between the proportions of people with anxiety about flying in each sample. What will be the shape of the sampling distribution of the difference in sample proportions, and why?
Answer: Approximately normal, because we expect 19.2 successes and 20.8 failures from people in their twenties, and 16.8 and 43.2 from people in their fifties, and all of these counts are at least 10.

7b-2/5 = 6b-7/5
Solve for b.
Answer:
b = -1
Step-by-step explanation:
here's your solution
=> 7b - 2/5 = 6b - 7/5
=> 7b - 6b = -7/5 + 2/5
=> b = (-7+2)/5
=> b = -5/5
= b = -1
hope it helps
Answer:
b = -1
Step-by-step explanation: I put all the like terms together by moving 6b and -2/5, which then changed their signs to negative and positive, respectively.
7b-2/5 = 6b-7/5
7b-6b = 2/5-7/5
b = -1
