25. What is the value of the expression below? 36 ÷ 5 2 8 + 7 × (3 + 11)

Answer:

Step-by-step explanation:

The area of a trapezium is given as;

Area = [tex]\frac{1}{2}[/tex](a + b)h

where: a is the length of the upper side, b is the length of its base and h is its height.

This implies that; a = x - 4, b = x + 5, h = 2x and area = 351

Thus,

351 =  [tex]\frac{1}{2}[/tex]((x - 4) + (x + 50)) 2x

      = (x - 4 + x + 5) x

531 = (2x + 1) x

      = 2[tex]x^{2}[/tex] + x

So that;

2[tex]x^{2}[/tex] + x - 531 = 0

This gives a quadratic equation.

Brainliest ?!?!!?!?

Answer:

That depend on how much you spend on electricity, and how much other spending you do.

For example: If your electric bill is 100 dollars, and it increases 30 percent to 130, that’s 30 extra dollars. If your electric bill is only 50 dollars, it will increase to 65, that’s an extra 15.

What percentage that increase is of your current spending will vary according to how much you spend. If you only spend 30 dollars, then you’ll need to cut all of it, or half of it to offset the increases I mentioned above. That’s a 100 percent or 50 percent reduction.

If you spend 1000 dollars, you’ll only need to cut spending by 3 percent to get that 30 dollars, or 1.5 percent to get the 15 dollars.

It all depends on your specific values, you can’t say “For every xx percent your electric bill increases, you need to cut spending by yy percent.”

for the consumption of X unit let u spends Y

for X - Y cost

for increased 30% means 13X/10 - 13Y/10 cost

extra money is 13Y/10 - Y = 3Y/10

note: hope this helps :)

thus (3Y/10)/ (13Y/10) *100 % = 300 / 13 = 23.07%.

Answer:

112.5 divided by 15=7.5

112.5 divided by 15=7.5 equation is true answer.

Given option are:

15 divided by 112.5 = 7.5

15 ÷ 112.5 = 0.1333

This option is wrong.

15 divided by 112.5 = 75

15 ÷ 112.5 = 0.1333

This option is wrong.

112.5 divided by 15 = 7.5

112.5 ÷  15 = 7.5.

This option is right.

112.5 divided by 15 = 75.

112.5 ÷  15 = 7.5.

This option is wrong.

Therefore, the correct equation is 112.5 divided by 15=7.5

Answer:

x<-3

Explanation:

Divide both sides by -2 to isolate x.

Since you have divided by a negative number and it changed the positive number to a negative one, you'll need to change the direction of the sign to now reflect that.

The linked answer is wrong because that integral gives you the net displacement of the object, not the total distance.

To get the distance, you have to integrate the speed (as opposed to velocity), which involves integrating the absolute value of the velocity function.

[tex]\mathrm{distance} = \displaystyle\int_1^5 |\sin(t)| \,\mathrm dt[/tex]

By definition of absolute value,

[tex]|\sin(t)|=\begin{cases}\sin(t)&\text{for }\sin(t)\ge0\\-\sin(t)&\text{for }\sin(t)<0\end{cases}[/tex]

Over this particular integration interval,

• sin(t ) ≥ 0 for 1 ≤ t < π, and

• sin(t ) < 0 for π < t ≤ 5

so you end up splitting the integral at t = π as

[tex]\mathrm{distance} = \displaystyle\int_1^\pi \sin(t)\,\mathrm dt + \int_\pi^5 (-\sin(t))\,\mathrm dt[/tex]

Now compute the distance:

[tex]\mathrm{distance} = -\cos(t)\bigg|_1^\pi + \cos(t)\bigg|_\pi^5[/tex]

[tex]\mathrm{distance} = -(\cos(\pi) - \cos(1)) + (\cos(5) - \cos(\pi))[/tex]

[tex]\mathrm{distance} = -2\cos(\pi) + \cos(1) + \cos(5) \approx 2.82[/tex]

making B the correct answer.

The cost per pound is: $5.45 per pound

Step-by-step explanation:

Given

8kg ham costs $12/kg

To determine

Find the cost per pound

As

1 kg = 2.2 pounds  

Weight of 8kg in ponds = 8 × 2.2 = 17.6 ponds

Cost of ham/pound = $12/2.2 pounds

                                 = $5.45 per pound

Thus, the cost per pound is: $5.45 per pound

Answer:

She gives 2 apples to each horse, and there will be 3 apples left.

Step-by-step explanation:

We know that Mia has 4 horses and 11 apples

She gives each horse the same number of apples, such that she uses the maximum number of apples that she can.

If she has 4 horses and she gives the same amount to each horse (let's say that this amount is N apples to each horse)

Then she uses a total of 4*N apples.

Then if N  =  1, she needs 4*1 = 4 apples.

if N = 2, she needs 4*2 = 8 apples.

if N = 3, she needs 4*3 = 12 apples.

But she has only 11 apples, so she can not give 3 apples to each horse.

Then the maximum number of apples that she can give to each horse is N = 2, 2 apples to each horse.

Now, we know that she has 11 apples in total, and she gives 2 to each of the 4 horses, then she gives:

4*2 = 8 apples.

The number of apples that are left are:

11 - 8 = 3

There are 3 apples left.
