-2-0.5b+12=0.3b+6.2 ​

Answers

Step-by-step explanation:

-2 -0.5b + 12 = 0.3b + 6.2

-2 + 12 - 6.2 = 0.3b + 0.5b

3.8 = 0.8b

b = 3.8/0.8

= 4.75

Answer:

4.75

Step-by-step explanation:

-2-0.5b + 12 = 0.3b + 6.2

Move all terms to the left:

-2-0.5b + 12 - (0.3b + 6.2) = 0

Add all the numbers together, and all the variables

-0.5b - (0.3b + 6.2) + 10 = 0

Get rid of parentheses

-0.5b - 0.3b - 6.2 + 10 = 0

Add all the numbers together, and all the variables

-0.8b + 3.8 = 0

Move all terms containing b to the left, all other terms to the right

-0.8b = -3.8

b= -3.8/-0.8

b= 4+0.6/0.8

b= 4.75

Answer:

17*12 area of triangle is base*height

Answer:

Use the formula for the area of a triangle:

A = BH x 1/2

Where 'B' represents the base, 'H' the height, and multiplying by 1/2 just means dividing the product of those two lengths by 2.

What we know:

Base = 12 feetHeight = 17 feet

Which is all we need to know, so plug these values into our formula;

A = BH x 1/2

A = 12(17) x 1/2

Now just solve:-

A = 204 x 1/2

A = 204/2

A = 102, the area of this triangle is 102 ft²!

brelynn has a piece of ribbon that is 3/4 yard long. how many 1/12 yard pieces can she cut? help

Answers

The Brelynn can cut 9 pieces from the piece of ribbon that is 3/4 yard long of 1/12 yard.

What is a fraction?

Fraction number consists of two parts one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

Let's assume Brelynn can cut x pieces from the piece of ribbon that is 3/4 yard long.

So from the problem:

[tex]\rm \frac{\frac{3}{4} }{x} = \frac{1}{12}[/tex]

[tex]\rm \dfrac{3}{4} = \dfrac{x}{12}[/tex]

x = 9 pieces

Thus, the Brelynn can cut 9 pieces from the piece of ribbon that is 3/4 yard long of 1/12 yard.

The mean of five numbers is 8. If one of the five numbers is removed, the mean becomes 9. What is the value of the number that was removed

Answers

Using the mean concept, it is found that the value of the number that was removed was of 4.

What is the mean?

The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.

The mean of five numbers is 8, hence, the sum of the numbers is given by:

S = 5 x 8 = 40.

If one of the five numbers is removed, the mean becomes 9, hence, the sum of the four numbers is given by:

S = 4 x 9 = 36.

The difference is:

40 - 36 = 4.

Hence, the value of the number that was removed was of 4.

please help im not good with area and circumference when it comes to circles​

Answers

Note: the diameter is always twice as much the radius

1) r = 13cm
2) d = 27.2in
3) d = 24x
4) r = 24.5m

5) There is a circle inside a square, so the side of the square (16in), corresponds to the diameter of the circle.
radius = 8in
area = (pi)r^2 = 3.14 (8in)^2 = 3.14 (64in^2) = 200.96in^2
Circumference = 2(pi)r = 2(3.14)8in = 50.24in

6) The hypotenuse of the right triangle inside the circle is equal to the diameter of the circle. So we need to find it using the Pythagorean theorem.
d^2 = (10^2 + 24^2)cm
d^2 = (100 + 576)cm
d^2 = (676)cm
d = 26cm
So, radius = 13cm
Area = (pi)r^2 = 3.14 (13cm)^2 = 3.14 (169cm^2) = 530.66cm^2
Circumference = 2(pi)r = 2(3.14)(13cm) = 81.64cm

7) The diagonal of the square is equal to the diameter of the circle, so we need to find it using a formula.
d =[sqrt(2)] (5in)
I won’t calculate it now, because it’s a periodic number.
r = {[sqrt(2)] (5in)} : 2
Area = (pi)r^2 = 3.14 {[sqrt(2)(5in)]:2}^2 = 3.14 (12.5in^2)= 39.25in^2
Circumference = 2(pi)r = 2(3.14)(12.5in) = 78.5in

8) If a right triangle has two equal sides, it means that it is half of a square.
So we can apply the same formula as before.
d =[sqrt(2)] (8)
I won’t calculate it now, because it’s a periodic number.
r = {[sqrt(2)](8)}:2
Area = (pi)r^2 = 3.14 {[sqrt(2)(8)]:2}^2 = 3.14 (32) = 100.48
Circumference = 2(pi)r = 2(3.14)(32) = 200.86

The equation of a circle is shown. What is the radius? 22 + y2 - 10x + 8y + 16 = 0​

Answers

Answer:

radius = 5

Step-by-step explanation:

Given

x² + y² - 10x + 8y + 16 = 0

Using completing the square method

x² - 10x + 25 - 25 + y² + 8y + 16 (x + 5)² + (y + 4)² - 25 = 0(x + 5)² + (y + 4)² = 25

Standard form for equation of a circle

(x - h)² + (y - k)² = r², where r is the radius

On comparison to our equation in the question :

r² = 25radius = 5 [as distances cannot be -ve]

Answer:

The equation of a circle is shown. What is the radius?

----------------------------------------------------------------------------------

Equation of a circle

[tex](x-a)^2+(y-b)^2=r^2[/tex]

(where (a, b) is the center and r is the radius)

Given equation:

[tex]x^2+y^2-10x+8y+16=0[/tex]

Collect like terms:

[tex]\implies x^2-10x+y^2+8y+16=0[/tex]

Subtract 16 from both sides:

[tex]\implies x^2-10x+y^2+8y=-16[/tex]

Complete the square for both variables.

Add 25 to both sides for x.  Add 16 to both sides for y.

[tex]\implies x^2-10x+25+y^2+8y+16=-16+25+16[/tex]

[tex]\implies (x^2-10x+25)+(y^2+8y+16)=25[/tex]

Factor the two variables:

[tex]\implies (x-5)^2+(y+4)^2=25[/tex]

Therefore:

center of the circle = (5, -4)radius of the circle = √25 = 5

What is linear regression?

Linear regression is the most basic and commonly used predictive analysis. Regression estimates are used to describe data and to explain the relationship.

The difference between the linear model and the exponential model is the degree of difference of consecutive points. If their difference is constant, then it is more appropriate for the linear model. If their difference is increasing at a very fast rate, then that follows an exponential model. With that being said, let's look at the differences at every 6 month-intervals.
