Answers
Answer:
1)556.11 cm²
2)164.05 cm²
3)117.70 cm²
Step-by-step explanation:
1) We have a cylinder and a cone on top of it.
Formula for total surface area of cylinder is;
T.S.A = 2πrh + 2πr²
However, the top is not available for calculation here. Thus, we will use;
TSA = 2πrh + πr²
Thus;
TSA = 2π(5 × 12) + π(5)²
TSA = 455.53 cm²
The top is a cone but it's bottom is not included and so we will use lateral surface area of cone = πrL
L is the slanting height and can be calculated from pythagoras theorem ;
L = √(5² + 4²)
L = √41
Thus;
LSA = π × 5 × √41 = 100.58 cm²
Overall surface area = 455.53 + 100.58. Overall surface area = 556.11 cm²
2) for the box down;
TSA = 2lw + 2lh + 2hw
Since the top face is not used, then
TSA = lw + 2lh + 2hw
TSA = (5 × 5) + 2(5 × 5) + 2(5 × 5)
TSA = 125 cm²
For the prism on top, since the bottom is not included, we will use lateral surface are;. LSA = ½Pl
Where P is perimeter of base and L is slant height.
P = 5 × 4 = 20 cm
Radius is 5/2 = 2.5 and so using pythagoras theorem;
L = √(2.5² + 3²)
L = 3.905 cm
Thus;
LSA = ½ × 20 × 3.905 = 39.05 cm²
Overall surface area = 39.05 + 125 = 164.05 cm²
C) for the box down;
TSA = 2lw + 2lh + 2hw
Since the top face is not used, then
TSA = lw + 2lh + 2hw
TSA = (4 × 4) + 2(4 × 4) + 2(4 × 4)
TSA = 80 cm²
For the half cylinder on top;
Surface area ;
T.S.A = 2πrh + 2πr²
Since half cylinder;
TSA = πrh + πr²
TSA = π((2 × 4) + 2²))
TSA = 37.7 cm²
Overall total surface area = 80 + 37.7 ( 117.70 cm²

A florist arranged some orchid in bouquets of 20 and some roses in bouquets of 10 . She sells each bouquet of orchid for $25 and each rose bouquet for $30 . She earns $390 . If she sell four times as many orchid bouquets as rose bouquets. How many flowers does she sell all together?
Answers
Answer:
The florist sold 270 flowers.
Step-by-step explanation:
Since a florist arranged some orchid in bouquets of 20 and some roses in bouquets of 10, and she sells each bouquet of orchid for $ 25 and each rose bouquet for $ 30, and she earns $ 390, if she sell four times as many orchid bouquets as rose bouquets, to determine how many flowers does she sell all together, the following calculation must be performed:
4 x 25 + 1 x 30 = 130
8 x 25 + 2 x 30 = 260
12 x 25 + 3 x 30 = 390
12 x 20 + 3 x 10 = X
240 + 30 = X
270 = X
Therefore, the florist sold 270 flowers.

I attached my guess, since I don't see any graphs.
NOTE the x axis scale change on my submission.
Only option A graph matches the features of this polynomial. Therefore, option A is the correct answer.
What is a polynomial function?A polynomial is an equation with many terms whose leading term is the highest exponent known as a degree. The degree or exponent tells how many roots exist. These roots are the x-intercepts.
This polynomial has roots -3, 0, 1, and 3. This means the graph must touch or cross through the x-axis at these x-values. What determines if it crosses the x-axis or if the simple touch it and bounces back? The even or odd multiplicity - how many times the root occurs.
In this polynomial:
Root -3 has an even multiplicity of 2 so it only touches and does not cross through.
Root 0 has an odd multiplicity of 1 so crosses through.
Root 1 has an odd multiplicity of 1 so crosses through.
Root 3 has an even multiplicity of 3 so it only touches and does not cross through.
Knowing this, only the first and second graphs are possible answers.
Lastly, what determines the facing of the graph (up or down) is the leading coefficient. If positive, the graph ends point up. If negative, the graph ends and points down. All even degree graphs will have this shape.
Only option A graph matches the features of this polynomial. Therefore, option A is the correct answer.

Answers
Answer:
24 gallons
Hope this helps! :)
Answer: 192
Step-by-step explanation:
So we know the hose sprays 24 gallons of water a minute. We also know that 8 pints equal a gallon. So to figure out how many pints are in one minute, we multiply 8 x 24, since we have 24 gallons a minute and 8 pints equal a gallon. This equals 192 pints a minute.

A marketing research company desires to know the mean consumption of milk per week among people over age 31. A sample of 343 people over age 31 was drawn and the mean milk consumption was 4.4 liters. Assume that the population standard deviation is known to be 0.9 liters. Construct the 90% confidence interval for the mean consumption of milk among people over age 31. Round your answers to one decimal place.
Answers
Answer:
(4.3 ; 4.5)
Step-by-step explanation:
Given :
Sample size, n = 343
Sample Mean, xbar = 4.4
Standard deviation, σ = 0.9
Zcritical at 90%
Using the relation :
Xbar ± Margin of error
Margin of Error = Zcritical * σ/√n
Margin of Error = 1.645 * (0.9/√343)
Margin of Error = 0.0799394
Lower boundary = 4.4 - 0.0799394 = 4.320
Upper boundary = 4.4 + 0.0799394 = 4.480
(4.320 ; 4.480)

Solve the simultaneous equation
2x-3y =8 x+3y=14
Use elimination method....
Answers
Answer:
x = 22/3 y = 20/9
Step-by-step explanation:
2x-3y =8 x+3y=14
Add the two equations together to eliminate y
2x-3y =8
x+3y=14
-------------
3x +0y = 22
Divide each side by 3
3x/3 = 22/3
x = 22/3
Then take the second equation and multiply by -2 and add to eliminate x
2x-3y =8
-2x-6y=-28
----------------------
-9y = -20
Divide by -9
-9y/-9 = -20/-9
y = 20/9
x = 22/3 y = 20/9
