Answer:

hello. a= +2 and -2

Step-by-step explanation:

because it sais this two are similar so when x become 12 times so y should be the same so 3a2 equals with 12 so...

\(3 {a}^{2} = 12 \\ {a}^{2} = 4 \\ |a| = 2 \\ a = + - 2\)

Answer:

The answer is 140cm

Answer:

6 inches

Step-by-step explanation:

a = \(\pi r^{2}\)

113.04 = 3.14\(r^{2}\)  Divide both sides by 3.14

36 = \(r^{2}\)

\(\sqrt{36}\) = \(\sqrt{r^{2} }\)

6 = r

Answer:6 inches.

Step-by-step explanation: What is the radius of a circle with an area of 113.04 square inches?

Radius of the circle is of 3 inches.

Step-by-step explanation:

It is given that the area of the circle is 113.04,

Let the radius of the circle be of "a" units

=======================

From the properties of circle, we know : -

Area of circle = πr^2 , where r is the radius of the circle.

======================

Then, comparing the question with the identity :

= > πr^2 = 113.04 sq. inches

= > 3.14 x r^2 =  113.04 sq. inches

= > r^2 = 113.04 / 3.14 sq.inches

= > r^2 = 36 sq. inches

= > r = 6 inches

Hence,

r or radius of the circle is of 6 inches.

Answer:hi

Step-by-step explanation:

{11, 14, 22}

     Triangle Inequality Theorem states that two sides of a triangle must be greater than the third side.

     Using this method, the answer is {11, 14, 22} because 11+14>22, 11+22>14, and 14+22>11

x = 67°

Same-side interior angles are supplementary.

     x° + 113° = 180°

     x° = 180° - 113°

     x = 67°

r = 2°

     The little box represents 90 degrees, meaning that these angles are complementary.

     9r + 2° + 70° = 90°

     9r + 72° = 90°

     9r = 18°

     r = 2°

Answer:

y = 6x + 1 (0,2) (5,0)

Step-by-step explanation:

Really just need to pay attention where the x coordinate is at. If at 0, and the y coordinate is elsewhere, you will be able to tell where the y intercept is. Usually, you quickly draw a graph if the numbers are more complex.

I'm having trouble seeing but I think it's the one in the bottom left

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

Step-by-step explanation:

try it before u cry about it

Answer:

The answer is C

Step-by-step explanation:

A. 0.2 = 20%

B. 1/5 = 20% / 1 divided by 5 = .2

C. 4/16 = 1/4 = 25% / 1 divided by 4 = .25

The expression not equivalent to the 20% will be 4/16.

It is the ratio of two numbers expressed as a decimal of 100 parts. It is a measurement used to compare two sets of data, and it is stated as a percentage using the percent sign. Percentages are often and in many different contexts used.

It is given that the expression is 20%.

We have to find the equivalent value of 20%

Expressions that function identically while having distinct appearances are called equivalent expressions. If two algebraic expressions are equivalent, then they both have the same result when the same value of the variable is entered.

It can be written in different forms as,

=20/100

=1/5

=0.2

Thus, the nonequivalent expression of the % will be 4/16.
