Answer:

A ratio of 1/2 can be entered into the equivalent ratio calculator as 1:2. 2/10 would be 2:10, 3/4 would be 3:4 and so on.

Answer:

The mean is 30

Answer: 10 × 8 × 14 = 1120 it think 1120 is the answer cause the solution is length × width × height

Hope this helps :)

And plz mark me brainiest!

Answer:

V(x)=x^2+9x^2-16x-144

Step-by-step explanation:

Here the height of the figure is 14 yd.  The base appears to be an isosceles triangle.  The volume is the height times the base area:

V = (14 yd)(1/2)(16 yd)(10 yd), or

V(x)=x^2+9x^2-16x-144

Answer: A. The compromise allowed California to join the United States as a free state but would allowed slavery in the southwestern territories.

Step-by-step explanation:

As the abolitionist North and the pro-slavery South saw their rivalry intensify with the lobbying by the South that slavery should be allowed in the western territories, Congress decided to pass the compromise of 1850 which was several acts that would calm both sides for the time being.

With this compromise, California was allowed to join the United States as a free state but in return, the Southwestern territories were allowed to decide their slavery status in an election which meant that if the territories so pleased, they could allow slavery in their territories.

Step-by-step explanation:

The value of the digit 3 in the number 63,297 is 3,000 while the value of the digit 3 in the number 60,325 is 300.

The difference between value of the digit 3 in the number 63,297 and the value of the digit 3 in the number 60,325 will be:

= 3000 - 300

= 2700

Step-by-step explanation:

8 is the height and radius is half of the diameter. Just plug those into the equation

Answer:

4

Step-by-step explanation:

The slope of a line is given as the ratio of change in y to the change in x :

Change in y(dy) / change in x (dx)

Change in x = 1 ; change in y = 4

Slope = 4 / 1

The slope of the line = 4

Given:

The equation of a line is

[tex]y=-4x+10[/tex]

A perpendicular line on the given line passes through the point (4,-6).

To find:

The equation of the perpendicular line.

Solution:

We have,

[tex]y=-4x+10[/tex]

On comparing this equation with slope intercept form [tex]y=mx+b[/tex], we get

[tex]m=-4[/tex]

So, the slope of the given line is -4.

We know that the product of slopes of two perpendicular lines is always -1.

[tex]m\times m_1=-1[/tex]

[tex](-4)\times m_1=-1[/tex]

[tex]m_1=\dfrac{-1}{-4}[/tex]

[tex]m_1=\dfrac{1}{4}[/tex]

The slope of the required line is [tex]\dfrac{1}{4}[/tex] and it passes through the point (4,-6). So, the equation of the line is

[tex]y-y_1=m_1(x-x_1)[/tex]

[tex]y-(-6)=\dfrac{1}{4}(x-4)[/tex]

[tex]y+6=\dfrac{1}{4}x-1[/tex]

[tex]y=\dfrac{1}{4}x-1-6[/tex]

[tex]y=\dfrac{1}{4}x-7[/tex]

Therefore, the correct option is B.

Answer:

360:480

We know the total (840) so add the ratio: 3 + 4 =7

Divide 840 by 7 = 120

Multiply each part of the ratio by 120

3 x 120 = 360

4 x 120 = 480

Answer:

Step-by-step explanation:

Yes, the ordered number pair (72, 1/3) can readily be located on on a rectangular grid.  The x-coordinate is 72: draw a vertical line through 72.  The y-coordinate is 1/3; draw a horizontal line through y = 1/3.  

The point of intersection of these two lines is the graphical representation of the ordered number pair (72, 1/3).

Given:

The functions are:

[tex]f(x)=x^2-x[/tex]

[tex]g(x)=9-2x[/tex]

[tex]h(x)=x^2+2x-63[/tex]

To find:

The function [tex](f+h)(x)[/tex].

Solution:

We know that,

[tex](f+h)(x)=f(x)+h(x)[/tex]

Substituting the values of given functions, we get

[tex](f+h)(x)=x^2-x+x^2+2x-63[/tex]

[tex](f+h)(x)=2x^2+x-63[/tex]

Therefore, the required function is [tex](f+h)(x)=2x^2+x-63[/tex].

Answer:

k = ±[tex]\frac{10}{11}[/tex]

Step-by-step explanation:

121k² - 100 = 0

(11k + 10)(11k - 10) = 0

Answer:

multiply 36 by .20 and subtract that from 36

Step-by-step explanation:

20% is the amount off. if you multiply .20 and subtract it you'll get $7.20 so 36-7.20 which is $28.80.

Answer:

28.80 is 36 dollars 20 percent off.

Step-by-step explanation:

take the original price

divide the original price by 5

alternatively, divide the original price by 100 and multiply it by 20

subtract this new number from the original one

the number you calculated is the discounted value.

more simple steps:

1. subtract the final price from the original price

2. divide this number by the original price

3. multiply the result by 100

other explanation: a 20 percent discount is 0.20 in decimal format. secondly, multiply the decimal discount by the price of the item to determine the savings in dollars. for example: if the original price of the item equals 24$, y I u would multiply 0.2 by 24$ to GET $4.80

Given:

Initial cost of living = $44,000

Rate of increase = 5% = 0.05

To find:

The cost of living in 20 years.

Solution:

The exponential growth model is:

[tex]y=a(1+r)^t[/tex]

Where, a is the initial value, r is the growth rate and t is the number of years.

Putting [tex]a=44000,r=0.05, t=20[/tex] in the above model, we get

[tex]y=44000(1+0.05)^{20}[/tex]

[tex]y=44000(1.05)^{20}[/tex]

[tex]y=116745.099026 [/tex]

[tex]y\approx 116745.10 [/tex]

Therefore, the cost of living in 20 years is about $116745.10.

Answer:

(x-3)^2 + (y+2)^2 = 25

Step-by-step explanation:

Center is (3,-2) Radius is 5

3=h -2=k r=5

Formula (x-h)^2 + (y-k)^2 = r^2

Plug it in and switch the signs inside the ( )

(x-3)^2 + (y+2)^2 = 25

Area of small rectange = 7 cm × 4 cm = 28 cm sq

Area of bigger rectangle = 4cm×10 cm = 40 cm sq

Area of traingle = 1/2 × 8*3 cm sq = 12 cm sq

total area of polygon = ( 28 + 40 + 12 ) cm sq

area of polygon = 80 cm sq
