Answer:

Slope

Step-by-step explanation:

The equation of lines are normally formatted in "slope-intercept form"

find,
y
when

225

Answers

Answer:

y = 75

Step-by-step explanation:

Given that:

   y [tex]\alpha[/tex] [tex]\sqrt{x}[/tex]

⇒ y = k[tex]\sqrt{x}[/tex]

where k is the constant of proportionality.

When y = 45, x = 81, then;

45 = k[tex]\sqrt{81}[/tex]

45 = 9 k

k = [tex]\frac{45}{9}[/tex]

  = 5

k = 5

So that,

y = 5[tex]\sqrt{x}[/tex]

the value of y when x = 225 is;

y = 5[tex]\sqrt{x}[/tex]

  = 5 x [tex]\sqrt{225}[/tex]

  = 5 x 15

y = 75

In a maths class the girl to boy is 7:5 If there are 20 boys how many girls are in the class
​

Answers

Answer:

Let the total no of girls be x

the number of boys=7:5

total no of students =20

now,

no of girls =7/5=x/20

or, 20*7=5x

or 140=5x

or,x=140/5=28

therefore the number of girls =28

5x4=20 boys
So that means
7x4=28 girls

Step-by-step explanation:

Hello There!

First things first, we should find the rate of change / slope

given two points we can find the slope by using the slope formula which is

(let m be slope)

[tex]m = \frac{y_2-y_2}{x_2-x_2}[/tex]

To find the slope all we have to do is plug in the points

(1,5),(2,10)

remember the first numbers in an ordered pair are the x values and the second numbers are the y values

we also plug in the points of the second ordered pair first so

[tex]m=\frac{10-5}{2-1} \\10-5=5\\2-1=1\\m=\frac{5}{1} or5[/tex]

Knowing the slope we can create an equation to find the x value (a)

y=5x

given the y value we plug in y and solve for x

15=5x

divide each side by 5

15/5=3

5x/5=x

we're left with

x=3

so we can conclude when y =15 x = 3 therefore 3 is your answer

The following information relates to the lease agreement. 1. The term of the lease is 7 years with no renewal option, and the machinery has an estimated economic life of 9 years. 2. The cost of the machinery is $502,000, and the fair value of the asset on January 1, 2020, is $739,000. 3. At the end of the lease term, the asset reverts to the lessor and has a guaranteed residual value of $45,000. Novak estimates that the expected residual value at the end of the lease term will be 45,000. Novak amortizes all of its leased equipment on a straight-line basis. 4. The lease agreement requires equal annual rental payments, beginning on January 1, 2020. 5. The collectibility of the lease payments is probable. 6. Pharoah desires a 10% rate of return on its investments. Novak's incremental borrowing rate is 11%, and the lessor's implicitrate is unknown.1.
