Answer:

[tex]2 \dfrac25[/tex]

Step-by-step explanation:

The first pipe drains 1/4 of the pool every hour, and the second pipe drains 1/6 of the pool every hour. Combined, they drain [tex]\dfrac14 + \dfrac16 = \dfrac{5}{12}[/tex] of the pool per hour. Therefore, it will take 12/5 hours, or 2 2/5 hours.

(brainliest pls ty)

Both pipe are together then they take 6 hour to fill the pool.

In 1 hour they fill the pool is 110 hours

In 1 hour pipe A can fill the pool = x/1

​In 1 hour pipe B can fill the pool= y/1

​so

4 hours=x/4

6 hours=y/6

If both pipe are together then they take 6 hour to fill the pool.

If the are together then in 1 hour they fill the pool.

x/1 +  y/1 = 6/1+4/1= −−−−(1)

=10 hours

Example:A swimming pool may be filled using two pipes in 12 hours. Only half of the pool can be filled if the larger pipe is utilized for 4 hours and the smaller pipe for 9 hours.

10,000 divided by 240 minutes, or 4 hours, yields approximately 41.6. With the drain blocked, your pool would therefore fill at a rate of about 41 gallons per minute.

Answer:

The watermelon weighs 2,500 grams more than the cantaloupe.

Step-by-step explanation:

Giving the following information:

Watermelon= 5kg

Cantaloupe= 2,500 grams

We know that 1 kilogram equals 1,000 grams.

First, we need to determine the weight of the watermelon in grams.

Watermelon= 5*1,000= 5,000 grams

Now, the difference:

Difference= 5,000 - 2,500

Difference= 2,500 grams

The watermelon weighs 2,500 grams more than the cantaloupe.

y=2x+5

x=(y-5)/2

by using this rule

for

x=2. y=2×2+5=9

x=(23-5)/2=9. y=23.

Answer:

Step-by-step explanation:

y = 5x + 1

Table for input-output values is,

x        0         1           2           3

y        1          6          11          16          

Now we can plot these points to get the graph.

Step-by-step explanation:

Let her sales be represented by x.

Based on the information given in the question, the equation to calculate her sales goes thus:

(8.50 × 24) + (12% × x) ≥ 324

204 + (0.12 × x) ≥ 324

204 + 0.12x ≥ 324

0.12x ≥ 324 - 204

0.12x ≥ 120

x ≥ 120/0.12

x ≥ 1000

Her sales is at least $1000

Answer:

The size of the larger of the two segments = 6

Step-by-step explanation:

Attached below is the triangle  ( DOG )

perimeter of Triangle = 33

DO = 10

DG = 12

OG = x

formula for perimeter = DO + DG + OG = 33

                                   = 10 + 12 + OG = 33

hence: OG = 33 - ( 10 + 12 ) = 33 - 22 = 11

third side ( x ) = 11

Finally determine the length of the larger of the two segments of side ( OG)

from the diagram below

[tex]\frac{y'}{x'} = \frac{12}{10}[/tex]   -------------------- ( 1 )  

where x' = 11 - y'

hence equation 1 becomes

10y' = 12x'

10y' = 12 ( 11 - y' )

10y' = 132 - 12y'

22y' = 132

∴ y' = 132 / 22 = 6

hence x' = 5

Answer:

117

Step-by-step explanation:

Since we can see it is a parallelogram so

base (b) = 13 yd

height (h) = 9 yd

area of parallelogram

= b * h

= 13 * 9

= 117 square yards

Answer:

Area = b x h

Area = 13 x 9 = 117 yd²

Step-by-step explanation:

The equivalent to the complex number i³² is 1.

A complex number is a component of a number system that includes the imaginary unit, represented by the letter i as an extension of the real numbers.

Given:

i³²

As we know that i² = -1

The i³² can be written as,

(i²)¹⁶

Put the value of  i² = -1

(-1)¹⁶

As the power is an even number, so the result will be a positive number,

i³² = (-1)¹⁶ = 1

Step-by-step explanation:

I don't know how to explore the slope intercept line equation.  

However, 'b' is the y axis intercept (the point where is crosses the y axis and 'm' is the slope of the line.  The 'm' and the 'b' can be positive or negative numbers.  

A positive 'm' is a line that goes 'up' (the y value increases from the left to right) and a negative 'm' is a line that goes 'down' (the y value decreases from left to right).
