The required circumference of the gasket after dilation with scale factor 2 is 6.4 cm. Option C is correct.
A rubber gasket with a circumference of 3.2 cm is given. After expansion by scale factor 2 the circumference of the gasket is to be determined.
The circumference is defined as the boundary length of any circular shape.
Here,
Circumference of gasket = 3.2 cm
After dilation with scale factor 2, the circumference became.
Dilated circumference of gasket = 2*3.2 = 6.4 cm
Thus, the required circumference of the gasket after dilation with a scale factor of 2 is 6.4 cm.

What are the volume and the surface area of this storage chest?
Answer:
Surface Area: [tex]18ft^3[/tex]
Volume: [tex]44ft^2[/tex]
Step-by-step explanation:
Volume Formula --> base * height
[tex](4.5 * 2) * 2 = 9*2=18ft^3[/tex]
Surface Area Formula --> 2(width*length + height*length + height*width)
[tex]2((2*4.5) + (2*4.5)+(2*2)) = 2(9+9+4) = 2(22) = 44ft^2[/tex]
Answer:
Volume = 18 ft³
Surface area = 44 ft²
Step-by-step explanation:
Volume
Volume of a cuboid = base length × base width × height
Given:
base length = 4.5 ftbase width = 2 ftheight = 2 ftSubstitute given values into formula:
⇒ Volume = 4.5 × 2 × 2 = 18 ft³
Surface Area
Surface area = 2(base width × height) + 2(base length × height) + 2(base length × base width)
=2(2 × 2) + 2(4.5 × 2) + 2(4.5 × 2)
= 8 + 18 + 18

HELPP!!!! Tyrell is working on the middle school yearbook. He wants to fit a 4×6 inch photo into a space that is 3 inches wide. At what percent should he set the copier zoom button to achieve this size?
Answer:
50%
Step-by-step explanation:
Step one:
By convention, the dimension of a shape is described as
Lenght first, followed by width
Hence
lenght = 4 in
Width = 6 in
Step two:
Therefore, to achieve a new width of 3 in, the initial width must be divided by 2, which is a 50% reduction.
3/6*100
0.5*100
=50%
Answer:its 75 percent

Find the approximate length of C
Answer:
c = 2√3 ≈ 3.464
Step-by-step explanation:
A 30°-60°-90° triangle is a "special" triangle that has sides in the ratios ...
1 : √3 : 2 . . . . . shortest to longest.
Comparing those to the side measures you have, we see ...
1 : √3 : 2 = b : 3 : c
Multiplying the basic ratios by √3 gives a value that matches the long side:
√3 : 3 : 2√3 = b : 3 : c
Then the value of c is 2√3 ≈ 3.464.
_____
Additional comment
Side length b is √3 ≈ 1.732.
If the price of 4 dozens pencils is Rs. 264, what will be the price of 50 pencils?
Answer:
Rs. 275
Step-by-step explanation:
4 dozens = 4 × 12 = 48
4 dozens pencils = 48 pencils
48 pencils = Rs. 264
1 pencil = Rs. 264÷48
1 pencil = Rs. 5.50
50 pencils = 5.50×50
50 pencils = Rs. 275
Answer:
Rs. 275
Step-by-step explanation:
4 dozens = 48 pencils
48 pencils = Rs. 264
Find the price of 1 pencil to calculate the price of 50 pencils.
264 ÷ 48 = 5.5
1 pencil = Rs. 5.5
50 x 5.5 = 275
50 pencils = Rs. 275

Under his cell phone plan, Oliver pays a flat cost of $45 per month and $3 per gigabyte. He wants to keep his bill under $60 per month. Use the drop-down menu below to write an inequality representing g, the number of gigabytes he can use while staying within his budget
Answer: g < 5
5 is the amount of gigabytes
Oliver can use up to 5 gigabytes while staying within his budget of $60 per month.
The inequality representing the number of gigabytes Oliver can use while staying within his budget of $60 per month is:
3g + 45 ≤ 60.
where,
"g" represents the number of gigabytes used.
$3 is the cost per gigabyte.
$45 is the flat monthly cost.
$60 is the maximum budget.
Oliver pays a flat cost of $45 per month, which is represented by the constant term 45 in the inequality.
He also pays $3 per gigabyte, so the cost for the gigabytes used is 3g, where "g" represents the number of gigabytes.
The total cost (3g + 45) must be less than or equal to $60, as he wants to keep his bill under $60 per month.
Hence, the inequality is 3g + 45 ≤ 60.
Now, solve for g:
45 + 3g ≤ 60
Subtract 45 from both sides:
3g ≤ 15
Divide both sides by 3:
g ≤ 5
So, Oliver can use up to 5 gigabytes while staying within his budget of $60 per month.

Two similar geometric solids have a scale factor of 3:4. If the volume of the smaller solid is 54 cubic feet, what is the volume of the larger solid? Round to the nearest tenth as needed.
Thank you for your help!
Answer:
128 ft³
Step-by-step explanation:
given the scale factor of 2 similar solids is a : b , then
ratio of volumes = a³ : b³
here a : b = 3 : 4
then 3³ : b³ = 3³ : 4³ = 27 : 64
let x be volume of larger solid then by proportion
[tex]\frac{27}{54}[/tex] = [tex]\frac{64}{x}[/tex] ( cross- multiply )
27x = 3456 ( divide both sides by 27 )
x = 128
the volume of the larger solid is 128 ft³
Kendra and Dalisay practice archery. Kendra hits the target 3 times for every 5 misses. Dalisay hits the target 5 times for every 7 misses. Who hits the target more?
Using proportions, it is found that Dalisay hits the target more.
What is a proportion?A proportion is a fraction of a total amount.
Kendra hits the target 3 times for every 5 misses, that is, she hits the target 3 out of 8 times, hence her proportion is:
pK = 3/8 = 0.375.
Dalisay hits 5 out of 12 times, hence:
pD = 5/12 = 0.4167.
Due to the higher proportion, Dalisay hits the target more.

Alyssa is getting gas for her car. Her car’s 15-gallon tank has 1/5 a tank of gas left. If gas costs $2.699 per gallon, how much will she pay for gas, rounded to the nearest cent?
Answer:
$32.39
Step-by-step explanation:
She has a 15-gallon tank and it has 1/5 a tank of gas left (so about 3/15)
Because she needs to refill it and already has 1/5, she'll only need to pay for 4/5 a tank of gas (12/15).
So the equation should be 12 times $2.699.
12 × 2.699 = 32.388
Then, round to the nearest cent.
32.388 = $32.39
