Answer:

V=22/7×r^2×h

=22/7×(5.93/2)^2×10

=276.26cm

Step-by-step explanation:

Use the equation V=22/7×r^2×h

V=volume

r=radius

h=height

Substitute the values for r and h, then find the value for V

The volume of cylinder is 276.04 cm³.

The density of a cylinder is determined by its volume, which represents how much material may be immersed in it or carried inside of it. The formula πr²h, where r is the radius of the circular base and h is the height of the cylinder, determines the volume of a cylinder.

Given:

d= 5.93

h= 10cm

r= 5.93/2

Now, volume of cylinder

= πr²h

= 3.14 x 5.93/2 x 5.93/2 x 10

= 31.4 x 8.7912

= 276.04 cm³

Hence, the volume of cylinder is 276.04 cm³.

Answer: 1.67 feet in 1 second

Step-by-step explanation: To find out how far the penguin walked in 1 second, you’ll have to divide 10 by 6 or use the ratio 10 : 6 and divide. You should get a final answer or result of 1.67 feet in 1 second.

*Tip: If you want to make sure your answer is correct, simply multiply your answer times 6, and see if it equals to 10 or is near 10.

Answer:

5/3 ft

Step-by-step explanation:

10 ft = 6s

x ft = 1s

cross multiply

10ft × 1s = 6s × x

{divide both sides by The coefficient of x (6x) }

(10 ft × s) ÷ 6s= x

10 ft ÷ 6 = x

5/3 ft = x

x = 5/3 ft

Answer:

[tex]13x^{2}[/tex]-20x+8

Step-by-step explanation:

Step 1: rearrange the equation

16x^2 - 3x^2 - 7x - 13x +8

Step 2: solve the equation

16x^2 - 3x^2 = 13x^2

-7x - 13x = -20x

(the +8 will stay the same)

so when we put it all together it gives us

13x^2 - 20x + 8

Answer:

I think you are asking for the price Robert paid after the 30% off. There are two ways to do this. The first way is to find 30% of the full price and substract it from the full price or we could find 70% of the full price.

Lets make x the new price.

Step-by-step explanation:

First way:

x = 79.95 - (79.95 x 0.30)

x = 79.95 - 23.985

x = 55.965

(we round to the hundredth)

x = 55.97

Second way:

x = 79.95 x 0.70

x = 55.965

(we round to the hundredth)

x = 55.97

[tex]\overline{GB}[/tex] = 9

Step-by-step explanation:

The given parameters are;

The point of intersection of the perpendicular bisectors of the sides [tex]\overline{BC}[/tex], [tex]\overline{BA}[/tex], and [tex]\overline{CA}[/tex] intersect (meet) at point G

Let D represent the point of intersection of the perpendicular bisector from G to [tex]\overline{BC}[/tex], we have for ΔBGD and ΔCGD;

[tex]\overline{GD}[/tex] ≅ [tex]\overline{GD}[/tex] by reflexive property

∠GDB = ∠GDC = 90° given that [tex]\overline{GD}[/tex] is the perpendicular bisector of [tex]\overline{BC}[/tex]

Similarly, [tex]\overline{DB}[/tex] ≅ [tex]\overline{DC}[/tex], also given that  [tex]\overline{GD}[/tex] is the perpendicular bisector of [tex]\overline{BC}[/tex]

Therefore;

ΔBGD ≅ ΔCGD by Side-Angle-Side (SAS) rule of congruency

[tex]\overline{GB}[/tex] ≅ [tex]\overline{GC}[/tex]   by Congruent Parts of Congruent Triangles are Congruent, (CPCTC)

[tex]\overline{GB}[/tex] = [tex]\overline{GC}[/tex] = 9 by definition of congruency

∴ [tex]\overline{GB}[/tex] = 9.

Answer:

$525.62

$13,244.64

Step-by-step explanation:

A = P(1 + r/n)^nt

Where,

A = future value = ?

P = principal = $24,600

r = interest rate = 7.2% = 0.072

n = number of periods = 12

t = time = 6 years

A = P(1 + r/n)^nt

= 24,600(1 + 0.072/12)^12*6

= 24,600(1 + 0.006)^72

= 24,600(1.006)^72

= 24,600(1.5384)

= 37,844.64

12 months × 6 years = 72 months

Each monthly payment = Total payment / number of months

= $37,844.64 / 72

= $525.62

Total amount of interest = Total payment - Principal payment

= $37,844.64 - $24,600

= $13,244.64

Answer:

The history of irrational numbers, The discovery of irrational numbers is usually attributed to Pythagoras, more specifically to the Pythagorean Hippasus of Metapontum, who produced a (most likely geometrical) proof of the irrationality of the square root of 2. The story goes that Hippasus discovered irrational numbers when trying to represent the square root of 2 as a fraction. However Pythagoras believed in the absoluteness of numbers, and could not accept the existence of irrational numbers. He could not disprove their existence through logic, but his beliefs would not accept the existence of irrational numbers and so he sentenced Hippasus to death by drowning. Irrational numbers are important because without it we wouldn't have the continuum of real numbers which would make geometry impossible to do in life.

Answer:

George will swim 45 laps on Monday.

Step-by-step explanation:

The number is being increased by 9 each time, starting at 18 laps on Friday; it increases by 9 laps each day.

Answer:

45 laps on Monday; start at 18 and add 9 each time.

Step-by-step explanation:

The pattern is adding 9 each time. You can see that 18, 27, and 36 are all numbers that go up every time. They are all also multiples of 9. (9*2=18, 9*3=27, 9*4=36, etc.) So, if you add 9 to 36, it equals 45, so George swims 45 laps on Monday.

The y-intercept is where a line crosses the y-axis, which in this case is at -5.

First, we need to find how much Beatrice earns each month, so you need to find the difference between the two- and four-month amount and divide by 2, which gives you 150. So, we know she gets 150 dollars each month. Multiply that by two to get 300, and subtract that from 850 to see how much she was awarded in the beginning, which was 550. So, the answer is G.
