what percentage of students were surveyed between the ages of 10-13?

The answer to your question is 4x²(x+2)(4x²-3x+3)

Answer:

Step-by-step explanation:

Slope-intercept from: y = mx +c

Here, m is the slope & c is the y-intercept.

So, we have to isolate y. To isolate y first subtract 2x from both sides.

2x - 3y = -9

     -3y = -2x -9

Now, divide the entire equation by the co efficient of y (-3)

[tex]\dfrac{-3}{-3}y=\dfrac{-2}{-3}x-\dfrac{9}{-3}\\\\\\y=\dfrac{2}{3}x + 3[/tex]

Answer: Format of equation of vertical line: x = (x-coord of passing point.).

ANS : D.

Answer:

73 degrees

Step-by-step explanation

All quadrilaterals have interior angles that add up to 360 degrees

The sum of all the angles in a quadrilateral, a four-sided shape is 360 degrees, so we get the equation:

   [tex]x + 127 +87 + 73 = 360\\x + 287 = 360\\x = 73[/tex]

Therefore x = 73.

Hope that helps!

Answer:

B and Line HG

Step-by-step explanation:

1st One:

This one is kind of hard to explain without an image, but imagine the planes that those triangles are on went on forever. If you think about it, you'll realize that they intersect along line FG. You'll be able to learn how to do this with a little bit more practice.

2nd One:

The symbol above the HG stands for a line, because both ends go on forever. A ray would have one endpoint and one end going on forever, and a line segment would have two endpoints, so no arrows above it.

Answer:

acute angle

Step-by-step explanation:

An acute angle is less than 90 degrees.

Answer:

C. Acute

Step-by-step explanation:

There is no square so it's no a right.

It's not a straight because it's 180° which is a straight line.

It's not obtuse since it doesn't seem to be larger than 90°.

Answer:

This is a clear case to use the Pythagorean Teorem, as we need to calculate diagonal lenght of a rectangle, and to do so, we can divide it in right triangles.

As the Pythagorean Teorem says [tex]a^2 + b^2 = c^2[/tex]

We can now replace on [tex]a^2 + b^2 = c^2[/tex] the numbers we have [tex]24^2 + 32^2 = c^2[/tex]

Now, we solve [tex]24^2 + 32^2 = c^2[/tex] by operating:

[tex]\sqrt{1600} = b[/tex]; b = 40

The diagonal lenght is 40 inches r

[tex] \frac{71000}{12} = 5916.67[/tex]

if the one time agency fee is 38% of monthly salary'

($5916.67) (0.38) = $2248.33

Hey there!

4/7 + 5/6

≈ 24/42 + 35/42

≈ 24 + 36/ 42 - 0

≈ 59/42

≈ 1 17/42

Therefore, your answer is:

59/42 or 1 17/42

EITHER OF THOSE SHOULD WORK BECAUSE THEY ARE EQUIVALENT.

Good luck on your assignment & enjoy your day!

Answer:

corresponding angles- 4 and 8, 3 and 7, 1 and 5, 2 and 6

same side interior angles- 2 and 5, 3 and 8

alternate interior angles- 3 and 5, 2 and 8

alternate exterior angles- 1 and 7, 4 and 6

Step-by-step explanation:

The value of x from the expression is 12

Given the first five terms of a Fibonacci sequence expressed as:

a, 2a, 3a and 5a

If the sum of the first five terms is 228, hence;

a + 2a + 3a  + 5a + 8a = 228

19a = 228

a = 228/19

a = 12

Hence the value of x from the expression is 12

An absolute value function, which when graphed, represents the parent function, f(x) = |x|, reflected over the x-axis and translated 1 unit to the right include the following: B. f(x) = –|x – 1|.

In Mathematics, a reflection across or over the x-axis would maintain the same x-coordinate while the sign of the y-coordinate would either change from positive to negative or negative to positive.

This ultimately implies that, a reflection across the x-axis is given by this transformation rule: (x, y)  →  (x, -y).

By applying a reflection across or over the x-axis to the function, we have the following;

f(x) = -|x|

-f(x)' = |x|

f(x)' = -|x|

Next, we would translate the function to the right by 1 unit as follows;

f(x)' = -|x - 1|

:) have a good day/night!

Answer:

see explanation

Step-by-step explanation:

The figure has one pair of parallel sides and is a trapezoid.

Each lower base angle is supplementary to the upper base angle on the same side, thus

15x + 30 + 10x = 180 , that is

25x + 30 = 180 ( subtract 30 from both sides )

25x = 150 ( divide both sides by 25 )

x = 6

Also

3y + 18 + 90 = 180 , that is

3y + 108 = 180 ( subtract 108 from both sides )

3y = 72 ( divide both sides by 3 )

y = 24

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

2x, 90 and x lie on a straight line and sum to 180 , thus

2x + 90 + x = 180 , that is

3x + 90 = 180 ( subtract 90 from both sides )

3x = 90 ( divide both sides by 3 )

x = 30

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

2y and x are alternate angles and congruent , thus

2y = x = 30 ( divide both sides by 2 )

y = 15

Answer:

The answer is

Converting this into a geometry problem requires us to name the points. Let give the home plate a symbol A, first base will be B, second base will be C, and the third base will be D. Now, we can present a geometrical proof:

STATEMENTS | REASONS

(1) BC = CD | Given

m(2) AC = AC | Reflexive Property

(3) triangle ACD = triangle ACB | SAS Congruence

(4) AD = AB | CPCTC

when  CPCTC means Congruent Parts of Congruent Triangles are Congruent.

Therefore, the distance from first base to home plate, and from home plate to third plate are equal.
