If x is to 8 as 15 is to 12, then x equals...

Answer:

4y + 10

Step-by-step explanation:

Since the perimeter of a rectangle is 2(l + w), where l is the length and w is the width, the perimeter of this rectangle would be

2((y + 5) + y)

To simplify this, just add similar terms inside the parentheses and multiply them both by 2.

2(2y + 5)

4y + 10

Answer:

Option C, dP/dt=1/5P

Step-by-step explanation:

The change is population of insects is directly proportional to the rate of change of population

Hence,

[tex]\frac{dP}{dt} \alpha P[/tex]

Or [tex]\frac{dP}{dt} = kP[/tex]

where K is the proportional constant

We will find the value of k

Keeping the given values of rate of change of population and population in above equation, we get -

[tex]\frac{2}{10} = k\\k = \frac{1}{5}[/tex]

Hence,

[tex]\frac{dP}{dt} = \frac{1}{5} P[/tex]

Step-by-step explanation:

I drew a slope triangle and found the slope by finding the distance between two points on the line.

[tex]vertical distance/horizontal distance[/tex]

Hope this helped!

The slope of the line graphed in the coordinate grid will be;

⇒ m = -4/5

The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The line graphed in the coordinate grid is shown in figure.

Now,

Let two points on the graph of the line are (5, 0) and (0 , 4)

We know that;

Slope of the line passing through the points (x₁ , y₁) and (x₂, y₂) is,

⇒ m = (y₂ - y₁) / (x₂ - x₁)

Hence, Slope of the line  passing through the points (5, 0) and (0 , 4) is,

⇒ m = (y₂ - y₁) / (x₂ - x₁)

⇒ m = (4 - 0) / (0 - 5)

⇒ m = 4 / (-5)

⇒ m = -4/5

Thus, The slope of the graph = - 4/5

Answer:

-5n + 20

Step-by-step explanation:

n stands for the term number so if you want to find the 50th term all you have to do is substitute n with 50

first of all find the difference between each number in the sequence

the difference between 25 and 20 is -5

the difference between 20 and 15 is -5

the difference between 15 and 10 is -5

the difference between 10 and 5 is minis -5

because

25-5=20

20-5=15

15-5=10

10-5=5

now that you know the the difference you place the number in front of n like this

-5n

to find the rest all you need to do is use the difference between each number which is -5 and do it on the first number

so 25 - 5

this gives 20

so our nth term is -5n + 20

The process of solving a proportion is given below.

We are given that;

To show the process of solving a proportion

Now,

A proportion is an equation that states that two ratios are equal. For example, if we have 2 4 = 3 6[tex]{\\displaystyle {\\frac {2} {4}}= {\\frac {3} {6}}}[/tex] , then we have a proportion.

To solve a proportion, we need to find the value of a missing term that makes the equation true. There are different methods to solve a proportion, but one common method is cross-multiplication. Here are the steps to solve a proportion by cross-multiplication:

Multiply the numerator of one ratio by the denominator of the other ratio.

For example, if we have 2 4 = x 6

[tex]{\\displaystyle {\\frac {2} {4}}= {\\frac {x} {6}}}[/tex] , then we multiply 2 by 6 and get 12.

Multiply the denominator of the first ratio by the numerator of the second ratio.

For example, if we have 2 4 = x 6

[tex]{\\displaystyle {\\frac {2} {4}}= {\\frac {x} {6}}}[/tex] , then we multiply 4 by x and get 4x.

Set the two products equal to each other. For example,

if we have [tex]2 4 = x 6 {\\displaystyle {\\frac {2} {4}}= {\\frac {x} {6}}}[/tex], then we set 12 = 4x.

Solve for the missing term. For example, if we have 12 = 4x, then we divide both sides by 4 and get x = 3.

Check your answer by plugging it back into the original proportion.

For example, if we have x = 3, then we plug it back into 2 4 = x 6 [tex]{\\displaystyle {\\frac {2} {4}}= {\\frac {x} {6}}}[/tex] and get 2 4 = 3 6

[tex]{\\displaystyle {\\frac {2} {4}}= {\\frac {3} {6}}}[/tex] , which is true.

Therefore, by proportion answer will be given below.

Answer:

270 dollars

Step-by-step explanation:

He's going to watch 90 hours of tv in 30 days, so multiply 90 hours x 250 watts, Which is 22500 watts over 30 days, then convert to kilowatts which would be 22.5 kilowatts total. He used .25 kilowatts an hour every day. Then multiple 22.5 x 12 cents to get your answer 270. He paid 270 dollars for electricity for the tv.

Answer:

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

10% = 10/100 = 10 ÷ 100 = 0.1.

100% = 100/100 = 100 ÷ 100 = 1.

Increase the number by 10% of its value.

Percentage increase = 10% × 2,880

New value =

2,880 + Percentage increase =

2,880 + (10% × 2,880) =

2,880 + 10% × 2,880 =

(1 + 10%) × 2,880 =

(100% + 10%) × 2,880 =

110% × 2,880 =

110 ÷ 100 × 2,880 =

110 × 2,880 ÷ 100 =

316,800 ÷ 100 =

3,168

Calculate absolute change (actual difference)

Absolute change (actual difference) =

New value - 2,880 =

3,168 - 2,880 =

(g+4)=65

g=65-4

g=61degrees

The value of each variable in the parallelogram:

h = 9 and g = 61°.

A special form of quadrilateral called a parallelogram has both pairs of its opposite sides parallel and equal.

Given:

The shape is a parallelogram.

That means, the opposite sides are parallel and equal.

16 - h = 7

h = 16 -  7

h = 9

And opposite angles of a parallelogram are also equal.

g+4 = 65

g = 65 - 4

g = 61°

Therefore, the values are g = 61° and h = 7.
