Answer: With 11 pipes, you need 31.82 minutes to fill the tank.

Step-by-step explanation:

Let's define R as the rate at which one single pipe can fill a tank.

We know that 7 of them can fill a tank in 50 minutes, then we have the equation:

7*R*50min = 1 tank

Whit this equation, we can find the value of R:

R = 1 tank/(7*50min) = (1/350) tank/min.

Now that we know the value of R, we can do the same calculation but now with 11 pipes.

Then the time needed to fill the tank, T, is such that:

11*(1/350 tank/min)*T = 1 tank

We need to isolate T.

T = 1 tank/(11*(1/350 tank/min)) = 31.82 min

With 11 pipes, you need 31.82 minutes to fill the tank.

Answer:

369 m²

Step-by-step explanation:

Area of Triangle (sides): 1/2bh

=1/2(bh)

=1/2 (9•16)

=1/2 (144)

=72

There are four sides of the prism:

72•4=288

Area of Square (base): l•w

=9•9

=81

Surface Area = 288+81=369 m²

Answer:

369 m²

Answer: C) 2(2/5x+2) =2/5x+2 this would be the answer.

Step-by-step explanation:

Answer:

132 units

Step-by-step explanation:

the area of triangle = 1/2 × 6 × 8 = 24 units >>>1

the area of the rectangle = 3 × 8 = 24 units >>>2

the area of rectangle(2) = (21-(9+3)) × 8 = 9 × 8 =72 units >>>3

the area of triangle(2) = 1/2 × 3 × 8 = 12 units >>>4

then , from 1 , 2 , 3 and 4 the area of the figure = 24+24+72+12 = 132 units

Answer:

it's answer is 132

Answer:

35

Step-by-step explanation:

Let's make a system of equations for the vegetarian and chicken wraps; one for the total cost of them and one for the total amount sold.

Vegetarian wraps will be represented by variable v and chicken wraps will be represented by the variable c.

Subtract these equations.

Divide both sides by 2.40.

Substitute this value for c into the second equation.

Subtract 68 from both sides.

The number of vegetarian wraps sold amounted to 35 in total.

Answer :

Step-by-step explanation:

Then for the count we have :

→ count of vegetarian wraps + count of chicken wraps = 103

→ x + y = 103......[Equation (i)]

Then for the cost we have :

→ ❲$1.00 * x❳ + ❲$3.40 * y❳ = $266.20

Dropping the dollar signs we get :

→ ❲1.00 * x❳ + ❲3.40 * y❳ = 266.20

→ x + 3.40y = 266.20.....[Equation (ii)]

Substracting equation (i) from equation (ii) we get :

→ 0 + 2.4y = 163.2

→ 2.4y = 163.2

→ y = 163.2 ÷ 2.4

→ y = 68

Now, subsitute the value of y = 68 in equation (i) we get :

→ x + y = 103

→ x + 68 = 103

→ x = 103 - 68

→ x = 35

Answer:

0.0016283

Step-by-step explanation:

Given that:

Proportion of defective bulbs, p = 30% = 0.3

Sample size, n = 19 bulbs

Probability that the lot will pass inspection :

P(none of the 19 is defective) Or P(only one of the 19 is defective)

P(none of the 19 is defective) = (1 - p) ^n = (1 - 0.3)^19 ; 0.7^19

0.7^19 = 0.0011398

P(only one of the 19 is defective) :

P(1 defective) * P(18 not defective )

(0.3) * (1 - 0.3)^18

0.3 * 0.7^18

0.3 * 0.001628413597910449 = 0.0004885

Hence,

P(none of the 19 is defective) + P(only one of the 19 is defective)

0.0011398 + 0.0004885) = 0.0016283

Step-by-step explanation:

Answer:

I think the answer is B. The equation has infinitely many solutions.

Step-by-step explanation:

4(3x + 4) = 15x + 12 - 3x + 4

*group like terms so 4(3x+4) = 15x - 3x + 12 + 4

*add similar elements 15x - 3x = 12x

*add the numbers 12 + 4 = 16

*Expand to 12x + 16 - 16 = 12x + 16 - 16

*You simplify 12x = 12x

*Subtract 12x from both sides

*Then Simplify which is 0

Which means Both sides are equal to 0

Given:

1 set requires 4 couples 8 dancers.

Total number of people at a square dance = 250.

To find:

The greatest number of sets possible at the dance.

Solution:

We have,

Total people = 250

1 set = 8 people.

[tex]\text{Number of possible sets}=\dfrac{\text{Total people}}{\text{People required for 1 set}}[/tex]

[tex]\text{Number of possible sets}=\dfrac{250}{8}[/tex]

[tex]\text{Number of possible sets}=31.25[/tex]

Number of possible sets cannot be a decimal or fraction value. So, approx. the value to the preceding integer.

[tex]\text{Number of possible sets}\approx 31[/tex]

Therefore, the number of possible sets at the dance is 31.
