Answer:

x = 3

Step-by-step explanation:

Measure of a triangle is 180° degree.

.·. 46 + 105 + 6x + 11 = 180

.·. 162+6x=180

.·. 6x=180-162

.·. 6x= 18

.·. x= 18/6

.·. x= 3

Answer:

41 yards greater is the perimeter of 1st triangular field than the perimeter of 2nd triangular field.

First we have to calculate the perimeter of 1st triangle.

Given:

a = 33 yards

b = 56 yards

c = 65 yards

Now we have to calculate the perimeter of 2nd triangle.

Given:

a = 26 yards

b = 49  yards

c = 38 yards

Now we have to calculate which triangle has greater perimeter and how much greater.

Therefore, 41 yards greater is the perimeter of 1st triangular field than the perimeter of 2nd triangular field.

Step-by-step explanation:

(154-113)

41 yards bigger

Answer:

41 yds

Step-by-step explanation:

33+56+65=154

26+49+38=113

154-113=41 yds

Answer:

√15

Step-by-step explanation:

Assuming that it is:

[tex]15^\frac{1}{2}[/tex]

Exponent rule for fractional exponents are:

[tex]x^\frac{a}{b}=\sqrt[b]{x^a}[/tex]

Apply rule:

[tex]15^\frac{1}{2}=\sqrt{15}[/tex]

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.

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 and Step-by-step explanation:

The key for this has a current age and a future age. Sometimes these problems have more than one person or has a past age.

       current age     future age

        x                    x+45

The future age is 4 times current age

x+45 = 4x

   45 = 3x

   15 = x

She is currently 15. 45 years from now she will be 60.

60 is 4 times her current age. So right now, she is 15.

Answer:

The  constant of proportionality k = 12

Hence, option A is true.

Step-by-step explanation:

We know that when 'y' varies directly with 'x', we get

y ∝ x

y = kx

Where 'k' is called the constant of proportionality.

In our case,

The given equation is

y = 12x

comparing with the equation y = kx, we can say

k = 12 which is the constant of proportionality.

Therefore, we conclude that:

The  constant of proportionality k = 12

Hence, option A is true.

Answer:

[tex]y=-10x+43[/tex]

Step-by-step explanation:

We need to put this line into slope-intercept form, which is [tex]y=mx+b[/tex], where [tex]m[/tex] is the slope and [tex]b[/tex] is the [tex]y[/tex]-intercept.

The slope is rise over run, how much the [tex]y[/tex] value changes for one [tex]x[/tex] value. This can be found with the equation: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex] where [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are points on the line. Plugging in the first two points:

[tex]m=\frac{3-13}{4-3}=-10/1=-10[/tex]

We know them that [tex]m=-10[/tex]. This gives us for now [tex]y=-10x+b[/tex].

Now, to solve for [tex]b[/tex], plug in any one of the points (I'll use (3,13)):

[tex]13=-10(3)+b[/tex]

[tex]13=-30+b[/tex]

[tex]b=43[/tex]

This gives us the equation [tex]y=-10x+43[/tex].
