I'm guessing the "-ins" is "fifths". A fifth of 25 is 5 (25/5), so multiplying 5 by 4 will get you four-fifths. 20 students like football.

The exact volume of the cylinder is 375π cm³.

Solution:

Given image is a cylinder.

Radius of the cylinder = 5 cm

Height of the cylinder = 15 cm

The value of π = 3.14

Volume of the cylinder = πr²h

                                      =  π × 5² × 15

                                      = π × 25 × 15

                                      = π × 375

Volume of the cylinder = 375 π cm³

The exact volume of the cylinder is 375π cm³.

Answer:

A, C, and E but I could be wrong.

Step-by-step explanation:

A because 50 - 17 = 33 so -33 will be your answer for that one.

C because the answer of 50 - 17 = 33.

E because 17 + 23 = -40 so the difference between the pelican and the trout is -40 feet altogether.

48 ⅛-pint tubes can be filled.

To find out how many tubes can be filled:

Convert ¾ pint to eighths: ¾ pint = 6 eighths

Divide the total eighths by the eighths per tube: 6 eighths ÷ ⅛ eighths per tube = 6 ÷ 0.125 = 48 tubes

So, from a ¾-pint bottle of hydrogen peroxide, 48 ⅛-pint tubes can be filled.

Answer:

radius of the cylinder = 3inches (to the nearest tenth)

Step-by-step explanation:

the height of the cylinder = 6inches

volume of water in the cylinder = 60inces³

radius of the cylinder =?

π = 3.14

recall that ,

the fomular for finding the volume of a cylinder  = πr²h

the volume of a cylinder  = πr²h

the volume of a cylinder  = 3.14 × r² × 6

60 = 18.84r

divide both sides by 18.84

60/18.84 = 18.84r/18.84

Answer:

9 hrs and 10 mins

Step-by-step explanation:

We can convert this into a proportion. 50/45 = x/495. Cross-multiply to get 45x = 50*495. Divide both sides by 45 to get x = 50*11 = 550 minutes or 9 hrs and 10 mins

Answer: 445.5 minutes

Step-by-step explanation:

Hi, to answer this we have to apply a proportion:

Proportion: square feet / time (minutes)

Tim installs 50 square feet of his floor in 45 minutes: 50/45

For 495 square feet: 495/x

Where x is the time it takes Tim to install 495 square feet of his floor.

50ft/45min = 495ft/x min

Solving for x

x = 495 / (50/45)

x= 445.5 minutes  

Answer:

21/22 or 0.955 (3 sf)

43/66 or 0.652 (3 sf)

Step-by-step explanation:

P(atleast 1 Democrat)

= 1 - P(no Democrat)

= 1 - (6C4/11C4)

= 1 - 1/22 = 21/22 or 0.955 (3 sf)

P(atleast 2 Democrats)

= 1 - P(0 or 1 Democrats)

= 1 - 1/22 - (6C3×5C1)/11C4

= 1 - 1/22 - 10/33

= 43/66 or 0.652 (3 sf)

The probabilities that the new subcommittee will contain at least 2 Democrats are 0.955 (least 1) and 0.652 (least 2).

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

To calculate the probability that the new subcommittee will contain at least 1, Democrat

⇒ 1 - P(no Democrat)

⇒ 1 - (⁶C₄/¹¹C₄)

⇒ 1 - 1/22

⇒ 21/22

⇒ 0.955

To calculate the probability that the new subcommittee will contain at least 2, Democrat

⇒ 1 - P(0 or 1 Democrats)

⇒ 1 - 1/22 - (⁶C₃×⁵C₁)/¹¹C₄

⇒ 1 - 1/22 - 10/33

⇒ 43/66

⇒ 0.652.

Thus, the probabilities that the new subcommittee will contain at least 2 Democrats are 0.955 (least 1) and 0.652 (least 2).

To determine the number of different ways a math teacher can select 6 students from a class of 30, we use the combination formula C(30, 6) = 30! / (6! * (30 - 6)!), which gives us 593,775 different possibilities. Therefore, the correct answer is C, 593,775.

The math teacher needs to select 6 students from a class of 30 students to go to the library, which is a combinatorial problem in mathematics. The number of ways to choose k students from a group of n students without regard to the order is given by the combination formula:

C(n, k) = n! / (k! * (n - k)!), where n! is the factorial of n and equals n multiplied by all positive integers less than n, and k is the number of students chosen.

Applying the formula for our situation:

C(30, 6) = 30! / (6! * (30 - 6)!)
= (30 * 29 * 28 * 27 * 26 * 25) / (6 * 5 * 4 * 3 * 2 * 1)
= 593,775

So there are 593,775 different ways the teacher can select 6 students from a class of 30. Hence, the correct answer is C, 593,775.

The interest paid is Rs 10000

The rate of interest  is  20%

Step-by-step explanation:

Step 1 :

Amount  borrowed by Mr. Satyal = Rs 50000

Amount repaid  = Rs 60000

Interest is charged on the principal amount and the amount repaid will be the sum of the interest paid plus the principal amount

Hence the interest paid is 60000 - 50000 = Rs 10000

Step 2:

The rate of interest is  calculated as follows :

Divide the interest calculated by the principal amount and is expressed as percentage.

Hence the interest rate  = [tex]\frac{10000}{50000}[/tex] × 100 = 20%

Answer:

54 cans

Step-by-step explanation:

8 Tennis ball launchers.

Each hold 27 balls.

One can = 3 balls.

We have 27 * 8 total balls which is equivalent to 216.

We want to find 3/4 of the total which is 216 * 0.75.

This is then = to 162

Since one can holds 3 balls.

162/3 = 54 cans.

Therefore, to fill the total of 3/4 of launchers within a lesson, 54 cans of tennis balls will be needed.

Answer:

Number of cans is 6.75

Step-by-step explanation:

According to the question,

One launcher holds 27 tennis balls

3/4 launcher hold y tennis balls

Cross multiply

Y= 3/4×27

Y= 81/4

Y= 20.25 tennis balls

To determine the number of cans

One can holds 3 tennis balls

Z can holds 20.25 tennis balls

Cross multiply

3z= 20.25

Z= 20.25/3

Z=6.75 cans

The total cost of the printer and scanner after the rebates is $117.86, and the actual rebate after expenses is $26.96.

For part a, first, add up the cost of the printer and scanner: $79.80 (printer) + $67.10 (scanner) = $146.90 (total original cost). Then calculate the mail-in rebates: $11 (printer rebate) + $17 (scanner rebate) = $28 (total rebates). However, you incur some costs when mailing these rebates. You need one envelope and one stamp for each rebate so multiplying the price of the envelope and the stamp by 2 gives us 0.15*2 + 0.37*2= $1.04. We subtract the $28 (rebate) and this $1.04 (mail cost) from the original cost ($146.90), giving us a final cost of $146.90 - $28 - $1.04 = $117.86.

For part b, the actual rebate after your expenses is the total value of the rebates ($28) minus the mail-in costs ($1.04), which ends up being $28 - $1.04 = $26.96.

Answer:

L = 90 inches

W = 30 inches

Step-by-step explanation:

Give the length of a rectangle L is three times the width

That’s

L = 3w

And perimeter = 240 inches

Recall that the perimeter of a rectangle is given by

P = 2(L + W)

L = 3w

We now have two equations

Now substitute 3w for L in The above formula and 240 for P.

We have

240 = 2(3w + w)

Distribute 2 into (3w + w)

240 = 2 x 3w + 2 x w

240 = 6w + 2w

240 = 8w

Divide both sides by 8

240/8 = 8w/8

30 = w

W = 30inches

Now substitute 30 for w into either of the above equations to get L .

Using

L = 3w

L = 3 x 30

L = 90 inches

L = 90 inches and

W = 30 inches

This is an isoscele trapezoid, because the 2 sides are equal and the bases are parallel.

This means:

5x+45=20x

y=z

5x+45=20x, 45=15x, x=3

The sim of all angles is 360⁰.

2×20x+y+z=2×60+2y=360

60+y=280, y=z=120⁰

Answer: x=3, y=z=120⁰

well, as we can see from the tickmarks on the slanted sides, they're equal, meaning is an isosceles trapezoid, meaning the angles up above are equal to each other, and the angles down below are also equal to each other, namely.

z = y and 5x + 45 = 20x.

[tex]\bf 5x+45=20x\implies 45=15x\implies \cfrac{45}{15}=x\implies \boxed{3=x} \\\\\\ 5x+45\implies 5(3)+45\implies \blacktriangleright 60 \blacktriangleleft\impliedby 20x[/tex]

well, the sum of all interior angles in a polygon is

180(n - 2), where n = sides

this trapezoid has 4 sides, so the sum of all its interior angles is 180(4 - 2) = 360°.

well, we know that the angles above are 60° each, so that's 120° for those, and 360° - 120° = 240°, so "z" and "y" will evenly split 240°, namely ∡z = ∡y = 120°.
