Step-by-step explanation:

Answer: 7.5 (h)

Step-by-step explanation:

Let say

a the outflow of the first pipe

b the outflow of the second pipe

T the volume of the tank.

x the time for filling with the second pipe

two pipes can fill a tank in 3 hours: a*3+b*3=T

One pipe alone can fill the tank in 5 hours : a*5=T

3*b=T -3a ==> 3b= 5a*3a=2a

b=2a/3

b*x=T ==> 2/3*a*x=T ==> 2/3*T/5*x=T ==> 2/15*x=1

x=15/2 = 7.5 (hours)

Answer:

remainder 25

Step-by-step explanation:

if 42,325 is divided by 47the result is 25,

firstly divide 42,325 by 47, you will see that it can only divide 42,325 which is 900 without any remainder,then the 900 is the whole number and 25 is remaining from the subtraction of 42,325-42,300=25 ,and 25 has to be divided by 47 but it is not up to 47,then we have it as a remainder,

so 25 is the remainder

Answer:

Step-by-step explanation:

2∠0PQ = 36

∠OPQ = 36/2 = 18°

Join OQ,

ΔOPQ is an isosceles triangle as OP = OQ = radius

∠OQP = ∠OPQ    {Angles opposite to equal sides are equal}

∠OQP = 18°

∠ORQ = 36

ΔORQ is an isosceles triangle as OR = OQ = radius

∠OQR =   ∠ORQ    {Angles opposite to equal sides are equal}

∠OQR = 36°

∠PQR = ∠PQO + ∠OQR

          = 18 + 36

∠PQR = 54°

∠POR = 2*∠PQR         {Central angle theorem}

          = 2 * 54

∠POR = 108°

∠PQR + ∠PSR = 180      {Opposite angles of cyclic quadrilateral}

54 + ∠ PSR = 180

            ∠PSR = 180 - 54

∠PSR = 126°

∠PSR + ∠RST = 180        {linear pair}

126 + ∠RST = 180

      ∠RST = 180 - 126

      ∠RST = 54°

Answer:

Perimeter= 221, Area=

Step-by-step explanation:

Perimeter is always addition of all sides.

73+56+92=221

Area=

S= (a+b+c)/2

= (73+92+56)/2

=221/2

ar(triangle)= [tex]\sqrt{221(221-92)+221(221-73)+221(221-56)}[/tex]

Hey there!

Guide:

• Negatives are on the LEFT side of the number line

• Positives are on the RIGHT side of the number line.

• Negatives are BELOW 0 (less than 0)

• Positives are ABOVE 0 (more than 0)

• You have to take the value of the LARGER number.

• If your LARGER number is a negative number then your result will be a negative.

• If your LARGER is a positive number then your result will be a positive

• Negative & Negative = Positive

• Negative & Positive = Negative

• Positive & Positive = Positive

• Positive & Negative = Negative

y = -50 + 31

• So, you start from -50 and go UP 31 spaces to the right because “31” is a positive number.. once when you have moved UP your 31 spaces you have reached your answer for this given equation

y = -50 + 31

y = -19

Therefore, your answer is: y = -19

Good luck on your assignment and enjoy your day!

Answer:

D(3, 3)

The slope of line AB is -2.

The slope of line CD is 1/2.

Step-by-step explanation:

I chose point D (shown in the figure below) since it lies on the intersection of grid lines and is easy to read. The coordinates of point D are (3, 3).

Point A(-3, 3); point B(-1, -1)

slope of line AB:

[tex] m = \dfrac{y_2 - y_1}{x_2 - x_1} [/tex]

[tex] m = \dfrac{-1 - 3}{-1 - (-3)} [/tex]

[tex] m = \dfrac{-4}{-1 + 3} [/tex]

[tex] m = \dfrac{-4}{2} [/tex]

[tex] m = -2 [/tex]

The slope of line AB is -2.

Point C(1, 2); point D(3, 3)

slope of line CD:

[tex] m = \dfrac{3 - 2}{3 - 1} [/tex]

[tex] m = \dfrac{1}{2} [/tex]

The slope of line CD is 1/2.

Answer:

y = - 85

Step-by-step explanation:

-y = 52 + 33 (52 flys over " = " and changes sign)

-y = 85

-y / - 1 = 85 / - 1 (getting rid of negative sign of y)

y = - 85

Answer:

For problem 15 it's y=15/4-7x

For problem 13 it's x=31-5y/6

Step-by-step explanation:

Problem 15:

y(4-7x)=15

y=15/4-7x

Problem 13:

6x=31-5y

x=31-5y/6

Answer:

13) Ans;

[tex]6x + 5y = 31 \\ 6x = 31 - 5y \\ \\ x = \frac{31 - 5y}{6} \\ \\ x = \frac{31}{6} - \frac{5y}{6} [/tex]

15)Ans;

[tex]4y - 7xy = 15 \\ y(4 - 7x) = 15 \\ \\ y = \frac{15}{4 - 7x} [/tex]

Answer:The first option has a higher cost per liter and the required cost is $1.40 per liter.

Step-by-step explanation:

Step-by-step explanation:  Given that a 2 liter bottle of juice cost $2.80. A box containing six 12 liter bottle sells for $3.90.

We are to select the option that has a higher cost per liter.

We will be using the UNITARY method to solve the given problem.

Option (1) :  

The cost of 2 liter bottle of juice = $2.80.

So, the cost of 1 liter bottle of juice will be

Option (2) :  

The cost of six 12 liters bottle of juice = $3.90.

So, the cost of 1 liter bottle of juice will be

Since 0.05>1.40, so the option of 2 liter bottle costing $2.80 has a higher cost per liter.

And, the required cost is $1.40 per liter.

5 m/s · 12 s = 5 m · 12 = 60 m

Answer: in 12 seconds that car has gone 60 metres.

Answer:

A car travels at a constant rate of 5 metres per second.

That means that for every second,the car travels 5m/s.

The question is asking you for how far the car travelled after 12 seconds.Muntiply 12 to bottom and top.

5m/1s*12/12=60/12

The car travels 60 metre in 12 seconds
