Answer:

Step-by-step explanation:

So the sum of 128 and x+10 is on a straight line which is 180º right?, so:

x + 10 + 128 = 180

x = 180 - 128 - 10

x = 42º

Answer:

42

Step-by-step explanation:

x +10 +128 = 180   {Linear pair}

x  + 138 = 180

x = 180 - 138

x = 42

If you‘re looking for the Circumference of a circle (since i didn’t really understand your question) C = 3 x 3.14 x radius (C is circumference aka perimeter btw)

Step-by-step explanation:

Answer: Area= 459.73cm^2

Step-by-step explanation: Circumference of a circle is 2πr

76=2×3.14×r

r= 76÷(6×3.14)

r=12.10

Area of a circle= πr^2

Area= 3.14×(12.10)^2

Area= 456.73cm^2

Based on the centroid theorem, the value of x is: 2.5.

The centroid theorem states that, the centroid of a triangle equals two-third of the distance from each midpoint of a triangle to each vertex.

Given:

BD = 4x + 5

BF = 9x

Thus:

BD = 2/3(BF)

4x + 5 = 2/3(9x)

4x + 5 = 6x

4x - 6x = -5

-2x = -5

x = 5/2

x = 2.5

Therefore, based on the centroid theorem, the value of x is: 2.5.

Answer:

23:18,23 to 18,23/18

Step-by-step explanation:

the three ways to write a ratio are colon,the word to, and the divide symbol .

The triangle that does not have the y angle, equate all of its angles to 180 degrees and solve for x. Once you solve for x, substitute that value to the angles in the other triangle, and then add them all up and equate it to 180 degrees to solve for y.

The reciprocal of a whole number is a fraction with the whole number as the denominator.

Set up the equation:

10 * 1/x = 5 * 1/3

Simplify:

10/x = 5/3

Multiply both sides by 3:

30/x = 5

multiply both sides by x:

30 = 5x

Divide both sides by 5:

x = 6

Answer: 2.4

Step-by-step explanation:

Because they are similar, the lengths of the sides will have the same ratio.

We will use side AB and side XY since it shows both sides.

This shows that the ratio is 3:4

We can then use that to find out that XZ also uses the ratio 3:4

3.2 / 4 = 0.8

0.8 * 3 = 2.4

XY is equal to 2.4

Answer:

Well I'm assuming some things based on my logic because I don't see the "five examples" but the normal lowest grade you can get and still get a A would be 90.0%. In order to get a A on a exam you need to understand the content of the exam. Some kids get A's on every exam for every class because they understand the content of their classes. Others get B's, C's, D's, and F's because they don't understand the content. Understanding content has nothing to do with you passing exams but how much effort you put into the class and studding.

Answer:

A. $202.80 EDGE

Step-by-step explanation:

The predicted price of a set that has 2,520 pieces is $202.8.

The correct option is (A).

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

y = 0.08x + 1.20

where x represents the number of pieces in a set and y is the predicted price.

So, for x= 2520 pieces the predicted price is

y= 0.08(2520)+ 1.20

y= 201.6 + 1.5

y= $202.80

Hence, the predicted price is $202.8.

Answer:

y=x+8

Step-by-step explanation:

m=y2-y1/x2-x1

First you choose one of your coordinate points to be 1 and one to be 2.

Then you substitute your x and y values into the equation above.

That way, you find the slope of the line.

For example i chose (-4,4) to be point 1 and (2,10) to be point 2.

m=10-4/2-(-4)

m=6/6

m=1

Next, you write the equation of a line.

y=mx+b

and you substitute the x and y values of one coordinate point into the equation. You also put m(slope) in, the one you just solved for.

I chose to substitute (2, 10)

10= 1(2)+b

Next, you solve for b

10=2+b

10-2=b

b=8

Now that you have b and your slope, you substitute those into the second equation

y=1x+8 or

y=x+8
