The equation is x + 487.75 = 1458. Then the value of the variable 'x' will be 970.25 liters.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The capacity of the hot tub is 1458 liters. Mrs. Smith filled the tub with 487 liters and 750 millimeters of water.

Let x be the amount of water that needs to be filled in the tub. Then the equation is given as,

x + 487.75 = 1458

Simplify the equation, then the value of the variable 'x' will be

x = 1458 - 487.75

x = 970.25 liters

The equation is x + 487.75 = 1458. Then the value of the variable 'x' will be 970.25 liters.

Answer: 3m+ 13 is greater

Answer:

The answer is $3.39

Step-by-step explanation:

the question states an increase in price. this means that we need to multiply the current prince ($2.67) by 127%.

drop the percent and put 127 over 100

[tex]\frac{127}{100}[/tex]

multiply

[tex]\frac{127}{100} *\frac{2.67}{1}\\\\ \frac{339.09}{100} \\\\3.39[/tex]

we are dealing with currency so rounding to the hundredths place will suffice.

The simplified value of (g - h) (g² - 3gh + 2h²) is equal to g³ - 4hg² + 5gh² - 2h³.

The expression given is (g - h) (g² - 3gh + 2h²)

We have to simplify the above polynomial expression.

What are the like terms in an expression ?

Like terms are the terms which contain the same variable which is raised to the same power i.e., 3m , 2m , 4m are like terms.

As per the question ;

The expression given is (g - h) (g² - 3gh + 2h²)

So ,

On solving the above expression we get ;

g³ - 3hg² + 2gh² - hg² + 3gh² - 2h³

Let's simplify this by adding similar variables ;

2gh² , 3gh² are same variables

i.e., 2gh² + 3gh² = 5gh²

Similarly ,

- 3hg² and  - hg² are same variables.

i.e., -hg² - 3hg² = -4hg²

So ,

The value after simplification will be ;

= g³ - 4hg² + 5gh² - 2h³

Thus , simplified value of (g - h) (g² - 3gh + 2h²) is equal to g³ - 4hg² + 5gh² - 2h³.

Answer:

The slope-intercept form is y=mx+b y = m x + b , where m is the slope and b is the y-intercept. Using the slope-intercept form, the slope is 3 .

Answer:

y=9x+2

Step-by-step explanation:

The standard form for a linear equation is y=mx+b. m=9 since it is slope and b=2 which is the y intercept. So the equation would be y=9x+2.

Answer:

8√2

2√2

Step-by-step explanation:

Using arc length for parametric equations:

s = ∫ₐᵇ √((dx/dt)² + (dy/dt)²) dt

x = 2 sin²t

dx/dt = 4 sin t cos t

y = 2 cos²t

dy/dt = -4 sin t cos t

s = ∫ √((4 sin t cos t)² + (-4 sin t cos t)²) dt

s = ∫ √(32 sin²t cos²t) dt

s = ∫ 4√2 sin t cos t dt

s = ∫ 2√2 sin(2t) dt

s = -√2 cos(2t)

If we evaluate this between t=0 and t=2π, we get s = 0.  This means the particle travels forward and backward on the same curve.

sin²t and cos²t have periods of π, so if we evaluate from t=0 to t=π/2:

s = -√2 cos(2 (π/2)) − -√2 cos(0)

s = √2 + √2

s = 2√2

So the particle travels 2√2 four times from t=0 to t=2π.

The distance traveled is 8√2.  The length of the curve is 2√2.

We can check our answer by eliminating the parameter.

x + y = 2 sin²t + 2 cos²t

x + y = 2

y = 2 − x

The curve is the line y = 2 − x from (0, 2) to (2, 0).  Using distance formula to find the length of the line:

d = √((x₂ − x₁)² + (y₂ − y₁)²)

d = √((2 − 0)² + (0 − 2)²)

d = 2√2

Hope This Helps :)

Answer:

36

Step-by-step explanation:

We have the ratio 3:6(girls to boys)

Now lets simply put 18 below the 3. We know 18 to something has to equal 3:6.

Simply divided 18/3=6

Now we have 6. Simply multiply it by the number of boys.

6*6, which equals 36 boys,

Your answer would be 36 boys

Now if we put 18:36, we get the ratio 3:6, which further reduces down to 1:2.

Hope this helps!

Maxwell takes time of 60 minutes to pack 8 boxes which is determined by the given rate of proportion.

A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.

We have been given that Maxwell takes 45 minutes to pack 6 boxes.

Let Maxwell takes time of x minutes to pack 8 boxes.

According to the given question, we can write a proportion as

45 minutes : 6 boxes = x minutes : 8 boxes

⇒ 45/ 6 = x / 8

⇒ 7.5 = x / 8

Apply the cross-multiplication operation,

⇒ x = 8 × 7.5

⇒ x = 60

Therefore, Maxwell takes time of 60 minutes to pack 8 boxes.
