Answer:

[tex]a^{2} + 2ab +b^{2}[/tex]

Answer:

20

Step-by-step explanation:

16/4=4

4*5=20

16=4/5 (80%) so 20= 5/5 (100%)

Answer: 20

Step-by-step explanation:

80/100 x Y = 16

80Y/100 = 16/1

Cross multiply

80Y = 1600

Divide both sides by 80

Y = 1600/80

Y = 20

Answer:

276

Step-by-step explanation:

6 is multiplied by 2 1/3 to get to 14. 70 divided by 2 1/3 is 30. The model of the train is 30 inches long.

Answer:

First we have to find the perimiter of the diagram

3+3+4+2=12

then we multiple by 4 which is 48 since the model is 1/4 the size

48 is the answer D

Hope This Helps!!!

Answer:

48

Step-by-step explanation:

(1/4) in = 1 feet

1 inch = 4 feet

3 in = 3*4 = 12 ft

2 in = 2 *4 = 8

4 in = 4 *4 = 16

Perimeter of actual deck = 12+ 12 + 8 + 16 = 48 ft

Answer:

  D.  5 units

Step-by-step explanation:

The parallel segments divide the slant segments proportionally:

  7.5/10.5 = x/7

  x = 7(7.5/10.5) = 5 . . . . . multiply by 7

The value of x is 5 units.

_____

If you want to use corresponding sides of similar triangles, you get the same result. ΔIGH ~ ΔIJK

  IJ/IG = IK/IH

  7/(7+10.5) = x/(x+7.5) . . . . substitute shown values

  7(x +7.5) = 17.5x . . . . . . . cross multiply

  7(7.5) = 10.5x . . . . . . . . . subtract 7x

 x = 7(7.5/10.5) = 5 . . . . . divide by the coefficient of x

Answer:

if your doing scientific notation then 2.7x10^3 would be the only one correct. if its not scientific notation then 27x10^3 would be more because it would be equivilent to 2700<27000

Step-by-step explanation:

Answer: B

Step-by-step explanation:

10 to the third power is 10*10*10

10*10=100

100*10=1000

2.7*1000=2700

Second Statement

10 to the power of 3 is 10*10*10

10*10=100

100*10=1000

Answer:

21

Step-by-step explanation:

Note that you are multiplying the values of A, B, & C together, and then subtracting the value of A from it. Plug in the corresponding numbers to the corresponding variables:

ABC - A

(3 * 4 * 2) - 3

(12 * 2) - 3

(24) - 3 = 21

21 is your answer.

Answer:

y = - 1/3x - 1/3

Step-by-step explanation:

Slope: - 1/3

y-intercept: -2 - (- 1/3)(5) = - 2 + 5/3 = - 1/3

Answer:

gracey

Step-by-step explanation:

find the equation of both graphs:

for gracey, she increases by 4 pounds every week, so her slope is 4, she starts out at 1 lb so b=1, so her graph is y=4x+1

for luna, she increases by 3 pounds every week, so her slop is 4 and she starts out at 2 lbs so b=2, her graph is y=3x+2.

plug in 5 for x in both equations to find out which y-value is greater, for gracey, y=21, for luna, y=17. 21>17 so gracey will weigh more at 5 weeks

Answer:

24.53 is your answer!

Step-by-step explanation:

add all of the numbers from the correct place values.

Answer:

Yes

Step-by-step explanation:

The way the equation is written in point-slope form is:

[tex]y-y1=m(x-x1)[/tex]

The way we write an equation in slope-intercept form is:

[tex]y=mx+b[/tex]

We can change point-slope form to slope-intercept form by first distributing the m and then adding y1 to both sides of the equation. When we do this we will get:

[tex]y=mx-(m*x+y1)[/tex] where [tex](m*x+y1) = b[/tex]

which is now in slope intercept form.

Answer:

14 days

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

25n+100=450

Step 2: Subtract 100 from both sides.

25n+100−100=450−100

25n=350

Step 3: Divide both sides by 25.

25n/25 =350/25

n=14

Answer:

Two weeks

Step-by-step explanation:

out of these 450, 100 are a flat, and it's 25 times the numer of days. In an equation form, [tex]450 = 100 + 25d[/tex]. The way you solve the equation, you subtract 100 to both sides, and divide by 25 (you can do it in the order you prefer!)

Step-by-step explanation:

What is the product of −2 1/2 and −3 1/3

Answer:

the value of x is 6 i believe

Step-by-step explanation:

What is value of x? Value of x is used to consider unknown value. The letter “x” is commonly used in algebra to indicate an unknown value. It is referred to as a “variable” or, in some cases, a “unknown.” In x + 2 = 7, x is a variable. But its value may be determined if we try! A variable need not be “x,” but might be “y,” "w," or any other letter, name, or symbol.

Answer:

3159.853 km

Step-by-step explanation:

The question says a square has an area of 9,984,670 km^2, which means that all sides are the same length. So you can use the equation:

9984670 = (x)(x) which rearranges to 998470 = x^2

get the square root and you get:

x = 3159.853 km

The required length of sides of the Canada is 3159.85 Kilometers.

Given that,
The total area of Canada is 9 984 670 km2. To calculate the side length of a square with the same area. Show your work.

Perimeter, is the measure of the figure on its circumference.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
The area of the square = 9984670
side × side = 9984670
side = √ 9984670
side = 3159.85

Thus, the required length of sides of the canacda is 3159.85 Kilometeres.

Answer:

89 degrees

Step-by-step explanation:

Answer:

89°

Step-by-step explanation:

The sum of all 3 angles in a triangles equals 180. If you add 50 to 41, you get 91. Then, you subtract 91 from 180, getting 89 degrees. Next, you square 89, add 170, subtract 12, add 3,218, subtract 3376, and find square root.
