Answer:

20.5 : 61.5

Step-by-step explanation:

1:3

1 + 3 = 4

82 ÷ 4 = 20.5

ratio of 1:3

1 × 20.5 = 20.5

3 × 20.5 = 61.5

20.5 : 61.5

Answer:

75

Step-by-step explanation:

for the square in the middle, 7x4=28

for the triangles on the left and right 7x5=35 and since there are two of them you dont need to divide by 2

for the triangles on top and bottom, 3x4=12 and also 2 of them so you dont need to divide by 2

then just add it all up

Answer:

the answer for this is 12

Answer:

Step-by-step explanation:

If we half the base of the equilateral triangle, which has a length of xcm, we can form a right-angled triangle with a base of x/2 cm and height 2√3 cm.

Now using Pythagoras' Theorem we solve for the hypotenuse:

[tex]x^{2} = (\frac{x}{2})^{2} + (2\sqrt{3})^{2}\\ x^{2} = \frac{x^{2}}{4} + 12\\ 4x^{2} = x^{2} + 48\\ 3x^{2} = 48\\ x^{2} = 16\\x = \frac{+}{}4\\ \\[/tex]

x must be positive as it is a length so we multiply 4 by 3 to get the perimeter of 12.

Answer:

f(-2) =-32

Step-by-step explanation:

f(x) = 5x* - 3x² + 6x + 2. f(-2)

f(-2) = 5(-2) - 3([tex]-2^{2}[/tex]) + 6(-2) + 2

f(-2) = -10 - 3(4) -12 + 2

f(-2) = -10 - 12 -12 + 2

f(-2) = (-10 - 12 -12) + 2

f(-2) = (-10 -24) + 2

f(-2) = (-34) + 2

f(-2) =-32

Hope that helps!

Answer:

[tex] \boxed{f( - 2) \: is \: - 32}[/tex]

Step-by-step explanation:

f(x) = 5x - 3x² + 6x + 2

f(-2) ?

substitute -2 as x into the equation of the function

f(-2) = 5(-2) - 3(-2)² + 6(-2) + 2

[tex]f( - 2) = - 10 - 3.4 + ( - 12) + 2[/tex]

[tex] f( - 2) = - 10 - 12 + ( - 12) + 2[/tex]

[tex] f( - 2) = - 22 - 12 + 2[/tex]

[tex]f( - 2) = - 32[/tex]

Answer:

Side length of first square is 10 cm

Side length of second square is 8 cm

Step-by-step explanation:

Let (x + 2) = side length of first square

Let x = side length of second square

Area of a square = (side length)²

⇒ area of first square = (x + 2)²

⇒ area of second square = x²

If the sum of their areas is 100 cm² then:

⇒ (x + 2)² + x² = 100

Expand the brackets:

⇒ x² + 4x + 4 + x² = 100

Collect and combine like terms:

⇒ 2x² + 4x + 4 = 100

Subtract 100 from both sides:

⇒ 2x² + 4x - 96 = 0

Divide both sides by 2:

⇒ x² + 2x - 48 = 0

Factor:

⇒ (x - 6)(x + 8) = 0

Therefore,

⇒ x = 6, x = -8

As distance is positive, x = 8 only.

Therefore, side length of first square is 10 cm

Side length of second square is 8 cm

Answer:

y = -2x + 3

Step-by-step explanation:

[]Let us write an equation in slope-intercept form.

-> See attached

-> Our equation will start out as y = x

[] The slope can be found by taking the change in y divided by the change in x

-> [tex]\frac{-3-1}{3-1}=\frac{-4}{2}=\frac{-2}{1}=-2[/tex]

-> Now our equation is y = -2x

[] The y-intercept, or b, can be found by plugging a point given to us into the equation we have so far.

-> y = -2x + b

(1) = -2(1) + b

1 = -2 + b

3 = b

-> Now our equation is y = -2x + 3, which is our final answer.

Answer:

y = -2x +3

Step-by-step explanation:

coordinates given (1,1) and (3,-3)

How to find equation? first find slope.

slope formula:

(y2-y1)/(x2-x1)

using this formula:

(-3-1)/(3-1)

-4/2

-2 ........this is slope also refereed as (m) in short form.

Use the formula:

y - y1 = m( x - x1)

using the formula:

y - 1 = -2( x - 1)

y -1 = -2x + 2

y = -2x +3

Answer:

  11.5

Step-by-step explanation:

Coordinate values and side lengths are multiplied by the dilation scale factor. (Angle values remain unchanged.)

  W'X' = (1/4)WX

  W'X' = (1/4)(46) = 11.5

Answer:

  A. 4,5

Step-by-step explanation:

No x-value can be repeated if the relation is to remain a function. The x-values already in the table are {-4, -2, 0, 2}. This list eliminates all answer choices except the first one: (4, 5) may be added to the table.

Answer:

I believe your answer is 76.

Chef Alfredo made the investment 4 years ago.

To solve this problem, we have to use the formula of simple interest.

Data;

The formula of simple interest is given as

[tex]S.I = \frac{PRT}{100}[/tex]

Let's subtract the principal from the final amount to know the simple interest

[tex]6000-4800=1200[/tex]

Substitute the values into the formula

[tex]s.i=\frac{prt}{100} \\1200=\frac{6000*5*t}{100}\\ 1200*100=6000*5*t\\120000=30000t\\t = 4[/tex]

Answer:

a. 60%

b. increase

Step-by-step explanation:

To find the percentage, you can divide 72 by 45 to get the decimal increase, or 1.6. Percentage rates are decimals, and you can think about this like coloring 60 circles out of 100, representing 60% of 100. Since 72 is higher than 45, this was a percentage increase.

The number that gives a value of 25 when 1/4 of the number is added to 4 is 80.

The first step is to represent the information in the question as an equation:

1/4x + 5 = 25

In order to determine the number, take the following steps:

Combine similar terms

1/4x = 25 - 5

Add similar terms

1/4x = 20

Multiply both sides of the equation by 2

x = 80
