Step-by-step explanation:
The two lids
Area = pi * r^2
d = 12
r = d/2
r = 12/2
r = 6 cm
Area = 3.14 * 6^2
Area = 3.14 * 36
Area = 113.04
Both Lids = 226.08

A ganza is a percussion instrument used in samba music.
a. Find the surface area of each of the two labeled ganzas in terms of π , rounded to the nearest thousandths and as a decimal, round to the nearest whole number.
Surface area of smaller ganza =
π≈
cm2
Surface area of larger ganza =
π≈
cm2
b. The weight of the smaller ganza is 1.1 pounds. Assume that the surface area is proportional to the weight. What is the weight of the larger ganza to the nearest tenth of a pound?
The weight of the larger ganza is about
pounds.
Answer:
1036.2 sq. cm
Step-by-step explanation:
The surface area of the smaller ganza = 2πr2 + 2πrh
surface area = 2 x 3.14 x 3.5 x 3.5 + 2 x 3.14 x 3.5x 10
surface area = 76.93+ 219.8
surface area = 296.73 sq. cm
The surface area of the larger ganza = 2πr2 + 2πrh
surface area = 2 x 3.14 x 5.5 x 5.5 + 2 x 3.14 x 5.5x 24.5
surface area = 189.97+846.23
surface area = 1036.2 sq. cm
a. The surface area of the smaller ganza is [tex]296.73cm^{2}[/tex]
The surface area of the larger ganza is [tex]1036.2cm^{2}[/tex]
b. The weight of the larger ganza is [tex]3.84[/tex] pounds.
Surface area :From given figure,
Radius of smaller ganza ,[tex]r_{1}=3.5/21.75cm[/tex]
height of smaller ganza, [tex]h_{1}=10cm[/tex]
a. The surface area of the smaller ganza is,
[tex]S_{1}= 2 \pi r^{2} + 2\pi rh[/tex]
[tex]S_{1}=2 * 3.14 * 3.5 * 3.5 + 2 * 3.14 * 3.5* 10\\\\S_{1}=76.93+ 219.8\\\\S_{1}=296.73cm^{2}[/tex]
The surface area of the larger ganza
[tex]S_{2}= 2\pi r^{2} + 2\pi rh[/tex]
[tex]S_{2}= 2 * 3.14 * 5.5 * 5.5 + 2 * 3.14 * 5.5* 24.5\\\\S_{2}= 189.97+846.23\\\\S_{2} = 1036.2 cm^{2}[/tex]
b. Since, the surface area is proportional to the weight.
and The weight of the smaller ganza is 1.1 pounds.
[tex]\frac{1.1}{w}=\frac{296.73}{1036.2}\\ \\ w=\frac{1036.2*1.1}{296.73}\\ \\w=3.84[/tex]

Tim Tradesman had a taxable income of $82,500. He figured his tax from the table above.
1. Find his earned income level.
2. Entered the base amount. = $
3. Found the amount over $ = $
4. Multiplied line 3 by % = $
5. Added Lines 2 and 4 = $
Answer:
Tax= $ 7,173.5
Step-by-step explanation:
Her taxable income is $ 43,000 which lies in the tax category $ 31,850 to
$ 77,100.
Tax for $ 31,850 is $ 4,386
Plus 25% of the amount = ( $ 43,000- $ 31,850 )= $ 11,150 over
25 % of $ 11,150= $ 2,787.5
Total Tax= $ 4386 + $ 2787.5= $ 7,173.5

Compare the speed of the train to the speed of the card. How much less time would it be for Lisa to travel 231 miles using the faster mode of tranportation? Show your work or explain how you determined your answer
Answer:
Faster mode: Car
Less time: 0.93 hour
Step-by-step explanation:
Given
[tex]y = 55x[/tex] --- The equation of travelling by car
See attachment for missing details
Required
Determine by how much less time Lisa will travel 231 miles using the faster mode
First, we calculate the equation of travelling by train.
Start by calculating the slope (m)
[tex]m=\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where
[tex](x_1,y_1) = (2,90)[/tex]
[tex](x_2,y_2) = (4,180)[/tex]
[tex]m = \frac{180 - 90}{4-2}[/tex]
[tex]m = \frac{90}{2}[/tex]
[tex]m = 45[/tex]
The equation is then calculated using:
[tex]y = m(x - x_3) + y_3[/tex]
Where
[tex](x_3,y_3) = (6,270)[/tex]
[tex]y = 45(x - 6) + 270[/tex]
[tex]y = 45x - 270 + 270[/tex]
[tex]y = 45x[/tex]
So, we have:
[tex]y = 55x[/tex] --- The equation of travelling by car
[tex]y = 45x[/tex] --- The equation of travelling by train
Next, we calculate the speed travelled using both means for 231 miles.
For travelling by car: Substitute 231 for y in [tex]y = 55x[/tex]
[tex]231 = 55 * x[/tex]
[tex]x = \frac{231}{55}[/tex]
[tex]x = 4.20[/tex]
By car, Lisa travels for 4.20 hours
For travelling by train: Substitute 231 for y in [tex]y = 45x[/tex]
[tex]231 = 45 * x[/tex]
[tex]x = \frac{231}{45}[/tex]
[tex]x = 5.13[/tex]
By train, Lisa travels for 5.13 hours
So, the faster mode of transportation is the car:
The less time is:
[tex]5.13 - 4.20 =0.93\ hour[/tex]
The less time spent is 0.93 hour

Thank you.
Answer:
D y=2x

the slope is 2 and when we plug the x value in it gives us our corresponding y value so the answer is D
Make a conjecture of what the x-intercepts of the function
f(x) = (2x - 1)(x + 3) will be.
Answer:
x=-3,x1/2
Step-by-step explanation:
f(x)=(2x-1)(x+3)
TI find x intercept/zero substitute
f(x)=0
0=(2x-1)x(x+3)
swap the sides of the equation
(2x-1)x(x+3)=0
when the product of factors equals 0,at least one factor is zero
2x-1=0
x+3=0
solve the equation for x
x=1/2
x+3=0
solve the equation of x
x=-3
The equation has two solution
x=-3
x=1/2

EXPLAIN why the solution to the absolute value inequality | 4x - 9 | ≥- 12 is all real numbers.
Answer:
no matter what value you substitute for x, the absolute value will force the result to be a positive number and any positive number is greater than -12
Answer: Since the absolute value of any number is always greater than or equal to zero, then the given inequality holds for every real number.
Explanation: It doesn't matter which number you substitute for x, as the absolute value will convert the number into a positive one, which will always be greater or equal to 0. Hence, every real number can be a possible answer.
