Answer:

The answer is 1500

Step-by-step explanation:

I multiplied 60 by 25

Answer:Its 1500

Step-by-step explanation:60 x 25

Answer:

$a decreased by 25% and $1.2a decreased by 40%

$a decreased by 25% = 0.75a

1.2a decreased by 40% = 0.6*1.2a = 0.72a

2) $b increased by 250% and $2b increased by 50%

$b increased by 250% = 2.5b

$2b increased by 50% = 1.5*2b = 3b

Answer:

b increased by 250% is equal to 2b decreased by 50%

$b increased by 250% > $2b increased by 50%

Answer:

Perimeter of one triangle is 65 dm

Perimeter of other triangle is 52 dm

Step-by-step explanation:

Please remember the concept

If sides are in the ratio of a:b

Then the area in the ratio of [tex]a^{2} :b^{2}[/tex]

It is given sum of their perimeter is 117.

Let the small triangle has perimeter as x.

So, perimeter of big triangle is 117-x.

So, we can set up equation as

[tex]\frac{50}{32} =\frac{x^{2} }{(117-x)^{2} }[/tex]

Cross multiply

50(117-x)^2 =32x^2

Expand the left side

50[tex](13689 -234x+x^{2} )[/tex]=[tex]32x^{2}[/tex]

Distribute the left side

684450-11700x+[tex]50x^{2}[/tex]=[tex]32x^{2}[/tex]

Subtract both sides [tex]32x^{2}[/tex] and rewrite it [tex]18x^{2} -11700x+684450=0[/tex]

Solve this quadratic for x.

Divide both sides of the equation by 18 to simplify.

[tex]x^{2}[/tex]-650 x+38025=0

Now, if possible let's factor

Find two integers whose multiplication is 38025 but adds to -650.

-65 and -585 works.

So, we can rewrite it as

(x -65)(x-585) =0

Solve them using zero product property

x=65, x=585

So, x=65 works here.

So, perimeter of one triangle is 65 dm

Perimeter of other triangle is 117-65= 52 dm

Step-by-step explanation:

Answer:

Are they going to build the fence on the edge of the pool?  How are they going to get into the pool?  This question is illogical, however....

Step-by-step explanation:

A square pool is also wierd.

Volume Pool = side × side × depth

Volume Pool / depth = side²                 solve for side

side² = Volume Pool / depth

the fence is 3.5 feet tall

Fencing sqft one side = side × fence height  for ONE side

Total Fencing = 4 × Fencing sqft one side

side² = 3464 ft³ / 8 ft

        = 422 ft²

side  =  √422 ft²

       =  20.54 ft

Fencing area one side  = 20.54 × 3.5

      = 71.899 ft²

Total fencing = 4× 71.899 ft²

     = 287.6 ft²      to the nearest tenth     <--------------------   FINAL ANSWER

Answer: y=5x+4

Step-by-step explanation:

Remember this

Slope-Intercept form: y=mx+b

m is the slope (5)

b is the y-intercept (4)

So your equation is

y=5x+4

Answer:

y = 5x + 4  

Step-by-step explanation:

y - 4 = 5(x - 0)

That is point-slope form. I'm not sure if you want it in slope-intercept form, but the slope-intercept form of the equation is -

y = 5x + 4

Step-by-step explanation:

∠RSQ = 180°-90°-34° = 56°

∠PSQ = 180°-∠RSQ = 124°

∠RPQ = (180°-∠PSQ)/2 = 28°

Answer:

c=150+25n

Answer:

51.26 ft

Step-by-step explanation:

First find the area of the triangle:

a=1/2 base times height

a=(1/2)(6)(4)

a=12 ft

Now find the area of the circles:

a= pi times radius squared

a= pi times 2.5 squared

a=19.63 ft

19.63 + 12 = 31.63 ft

Answer:

Negative

Step-by-step explanation:

Years of Factoring:

What the problem tells us is that we have:

X^2 - 4x - 3

or something along these lines. If we factor this we get:

(X-4)(X+1)

The bigger inside factor has to be negative for these problems, because the third term is negative.

The sum of the middle term must give a negative value.

A quadratic equation is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.

Given that If the middle term of a quadratic trinomial is negative and the last term is negative then the sum of the middle terms must give a negative value.

What the problem tells us is that we have:

x² - 4x - 3

Something along these lines. If we factor this we get:
