Total surface area of cone is 176π
Explanation:
Surface area of curved surface of a cone is give by π⋅r.l , where r is the radius and l is the slant height of the cone.
Hence surface area of curved surface of a cone is π×8×14=112π .
As surface area of base is π×82=64π .
Hence total surface area is 112π+64π=176π
The surface area of the given cone is 552.64 units²
What is surface area?The surface area of a solid object is a measure of the total area that the surface of the object occupies.
Given that, a cone has a radius of 8 and slant height of 14 units, we need to find its surface area,
The surface area of cone = π ·r²+ π·r·l, where l is the slant height,
So,
SA = (3.14 × 8²) + (3.14 × 8 × 14)
= 200.96 + 351.68
= 552.64
Hence, the surface area of the given cone is 552.64 units²

Which of the following situation illustrates combination
A TV has a listed price of $751.98 before tax. If the sales tax rate is 8.75%, find the total cost of the TV with sales tax included.
Round your answer to the nearest cent, as necessary.
Answer:
$817.78
Step-by-step explanation:
To find the tax you must do the equation:
751.98 x 0.0875
(Btw, 0.0875 is decimal form of 8.75%. Always turn the percentage into a decimal before finding the tax or sale amount)
751.98 x 0.0875 = 65.80.
Now, add the sale tax amount and the original price:
751.98 + 65.80 = 817.78
Therefore, the answer is 817.78.

Simplify the fraction.
Answer:
Step-by-step explanation:
cos θ=8/17
sin θ=√(1-cos²θ)=√(1-(8/17)²)=√(1-64/289)=√((289-64)/289)=√(225/289)=15/17
value of x if 3x+2y=11 and 5x-y=14
Answer:
3x + 2y = 11
3x + y = 11 - 2
3x + y = 9
x + y = 9/3
x + y = 3
x = 3 - y
5x - y = 14
x - y = 14/5
x - y = 2.8
x = 2.8 + y
14Answer:
3
Step-by-step explanation:
solve for y in first equation
5x-y=14
-y=14-5x
y=5x-14
substitute y value (5x-14) into 2nd equation
3x+2 (5x-14)=11
3x+10x-28=11
13x=39
x=3

Solve the following inequality
4 + 6x ≤ x + 6x
Select one:
A. x ≤ 4
B. x ≥ 4
C. x > 4
D. x < 4
Answer:
x ≥ 4
Step-by-step explanation:
The given inequality is :
4 + 6x ≤ x + 6x
Subtract 6x from both sides,
4 + 6x-6x ≤ x + 6x -6x
4≤ x
or
x ≥ 4
Hence, the correct option is (b) i.e. x ≥ 4.
HELPPPPP! Tamlin collects action figures and has 2 more female action figures than male action figures. He chooses two action figures randomly. Write and simplify an expression that represents the probability that Tamlin will pick two female action figures without replacing the first action figure. Let x be the number of male action figures.
Answer:
x+2/2(2x+1)
Step-by-step explanation:
Tamlin has x male action figures and x + 2 female action figures, so a total of x + x + 2, or 2x + 2 action figures. The probability of picking two female action figures without replacement is equal to the product of the probability of
-picking 1 female action figure from the total number and
-picking 1 female action figure after 1 has been removed.
The probability of picking 1 female action figure from the total is equal to the total number of female action figures divided by the total number of action figures.
The probability of picking 1 female action figure after 1 has been removed is equal to the total number of female action figures minus 1 divided by the total number of action figures minus 1.
Multiply these two expressions and simplify.
Answer:
The answer is x+2/2(2x+1)

What is the expected value of the spinner shown?
Answer:
4.5
Step-by-step explanation:
The Person who said C was correct but im just adding how to get it, just in case they ask you to show your work.
To find this answer you multiply each value by their probability, so 1 times 1/8, 2 times 1/8, 3 times 1/8, etc and all it all up.
Another way to find the answer is to add up all the values possible, 1+2+3+4+5+6+7+8, then divide by the amount of possibilities, in this case 8 because there are 8 sections on the spinner. This also gets you 4.5.

Which is an equation in terms of x and y for this function? graph of a function is a line that passes through the coordinates (2, 11) and (8, 14).
Answer:
y = 1/2x + 10
Step-by-step explanation:
I'm not sure if this is right but:
First you work out the gradient of the line which is the difference in y divided by the difference in x:
Gradient = (14 - 11) ÷ (8 - 2) = 3 ÷ 6 = 1/2
the gradient is 1/2 so you'd write that as: y= 1/2x + c
Then you need to work out the y-intercept ( c )
You do this by substitution:
14 = 1/2(8) + c
14 = 4 + c
c = 10
So the y-intercept is 10 so you'd write that as:
y = 1/2x + 10

Jackson purchased $5,200 worth of electronic equipment from BetterBuy on their deferred payment plan. The plan
allows the customer to make no down payment and no payment at all for five months. If the entire amount is paid in
full before the five month deferment ends, the finance charge with an APR of 19.8% is applied each month going
back to the first month. How much would it cost Jackson in finance charges if he misses the 5-month deadline?
Answer:
If Jackson misses the 5-month deadline, it will cost him $429 in finance charges.
Step-by-step explanation:
Since Jackson purchased $ 5,200 worth of electronic equipment from BetterBuy on their deferred payment plan, and the plan allows the customer to make no down payment and no payment at all for five months, while if the entire amount is paid in full before the five month deferment ends, the finance charge with an APR of 19.8% is applied each month going back to the first month, to determine how much would it cost Jackson in finance charges if he misses the 5-month deadline the following calculation should be performed:
5,200 x (1 + (0.198 / 12 x 5)) = X
5,200 x (1 + (0.0165 x 5)) = X
5,200 x (1 + 0.0825) = X
5,200 x 1.0825 = X
5.629 = X
5,629 - 5,200 = 429
Therefore, if Jackson misses the 5-month deadline, it will cost him $429 in finance charges.
