Help ASAP pleasee!!!!

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:

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:

108°

Step-by-step explanation:

Triangle LPM is similar to triangle MPN (they share MP, LP=NP and they both contain right angles.

This means that ∠LMP = ∠ PMN:

∠LMP = ∠ PMN

4x+2 = 7x-37

3x=39

x=13

∠LMN = ∠LMP + ∠ PMN

= 4(13)+2 + 7(13)-37

= 54 + 54

=108°

Answer:

( -3, 11)

Step-by-step explanation:

find the equation of the line between points ( -8, 11) and (-3, 11)

y= mx +b , where m is slope snd b is y-intercept

m = (y2-y1)/ (x2-x1) = 11-11/ -8- -3 = 0/ -5 = 0 ( if slope is o is a horizontal line)

y = 0x + b and pick a point to find b

11 = 0*-8 + b so b= 11

y = 11 is the equation of the line between points ( -8, 11) and (-3, 11) and the equation of its perpendicular line is x=-3

the equation of the line between points  (-3, 11) and ( -3, -12) is x= -3 and the perpendicular to it is y= 11

so we have a right triangle so the ortho center is at (-3, 11) where the vertex of the 90 degree angle is

Answer:

The numbers are [tex]-21[/tex] and [tex]17[/tex].

Step-by-step explanation:

If we let the numbers be [tex]x[/tex] and [tex]y[/tex], we can write the following system of equations to solve for them:

[tex]x+y=-4[/tex] (since the sum - which indicates addition - of the two numbers is [tex]-4[/tex])

[tex]x-y=-38[/tex] (since the difference - which indicates subtraction - of the two numbers is [tex]-38[/tex])

Solving for [tex]x[/tex] and [tex]y[/tex], we get:

[tex]x+y=-4\\x-y=-38[/tex]

[tex]2x=-42[/tex] (Add the two equations together)

[tex]x=-21[/tex] (Divide both sides of the equation by [tex]2[/tex] to get rid of [tex]x[/tex]'s coefficient and simplify)

[tex]-21+y=-4[/tex] (Substitute [tex]x=-21[/tex] into one of the equations, I chose the first one but it doesn't matter which one you choose)

[tex]y=17[/tex] (Add [tex]21[/tex] to both sides of the equation to isolate [tex]y[/tex] and simplify)

Therefore, the numbers are [tex]-21[/tex] and [tex]17[/tex]. Hope this helps!

Answer:

After 6 years, the company's annual sales will be $222,000

Step-by-step explanation:

8 percent of 150,000 is 12,000 which is the annual sale increase every year. Multiply that by 6 which is 72,000, the amount of annual sales after 6 years. Add that with 150,000 and you'll get 222,000.

Answer:

[tex]\cos\theta=\frac{10}{\sqrt{116}}[/tex]

Step-by-step explanation:

To solve this, we can imagine a line drawn directly down from the point (10,4) to the x-axis. This would make a right triangle with length 10 and height 4.

[tex]\cos\theta[/tex] is equal to the length of adjacent leg to the angle divided by the length of the hypotenuse of the triangle. From the picture, we can see the adjacent leg is 10.

We can use Pythagorean's Theorem to find the hypotenuse (let [tex]c[/tex] represent the length of the hypotenuse):

[tex]10^2+4^2=c^2[/tex]

[tex]100+16=c^2[/tex]

[tex]116=c^2[/tex]

[tex]c=\sqrt{116}[/tex]

Thus, we know the adjacent is 10, and the hypotenuse is [tex]\sqrt{116}[/tex]. This means [tex]\cos\theta=\frac{10}{\sqrt{116}}[/tex].

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:

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:

[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].

Answer:

15

Step-by-step explanation:

A square has 4 sides, so you can do 60 divided by 4 to find how many meters on each side.

60 / 4 = 15 meters for the side length

The side length of the square yard is 15 m.

A square is a two-dimensional figure that has four sides and all four sides are equal.

The area of a square is side².

We have,

The total length of the fence = 60 meters.

The square yard will have the same length on all four sides.

This means,

The side length of the square yard.

= 60/4

= 15

Thus,

The side length is 15 m.

Answer:

P odd number, then 20) = 1 /14

Step-by-step explanation:

P( odd number) =  number of odd numbers/ total

number of odd numbers = 3

total = 7

P( odd number)   = 3/7

We keep the tile so that there are only 6 tiles left

P (20) = number of 20/ total

         = 1/6

We multiply the probabilities together

P odd number, then 20) = 3/7 * 1/6 = 3/42 = 1 /14
