Answer:

b. x=24

Step-by-step explanation:

There are special formulas for finding the sides of a 30-60-90 triangle. The hypotenuse is always equal to 2a and the long leg is always equal to [tex]a\sqrt{3}[/tex].

Since side a is given already as 12. We can substitute 12 for a.

2(12) = 24

Answer:

T-shirt : £11

Hat : £7

Step-by-step explanation:

Think of T-shirts as T

and Hats as H

5t + h = 62

2t + h = 29  

we then subtract them both to cancel out h

3t = (62-29) = 33

now we divide 33 by 3  to find one t

33/3 = 11

so one t shirt is £11.00

now we substitute it back into the equation

2t ( 2x11 ) = 22

22 +h = 29

29 - 22 = 7

Answer:

∠ DEB = 52°

Step-by-step explanation:

The angle between a tangent and a chord is equal to the angle in the alternate segment, that is

∠ DEB = ∠ ABD = 52°

The short answer is that you use the tangent-chord theorem. A more lengthy answer is given below.

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

Explanation:

Refer to the diagram below.

I'm going to move point E so that segment EB becomes a diameter of the circle (it goes through the center point F). Points A,B,C,D will stay in place. The red points and red segments show the changes.

In this slightly redrawn diagram, triangle EDB is a right triangle where angle EDB is 90 degrees. This is due to Thales Theorem, which is a special case of the inscribed angle theorem.

Also, the new segment EB is perpendicular to segment AC because the diameter touching the point of tangency is perpendicular to the tangent line. So angle EBA is 90 degrees.

Since points A, D and B didn't move, this means angle ADB is still 52 degrees. This makes the new angle EBD equal to 90-52 = 38 degrees.

Despite the fact that angle E has moved, it has not effected the size of angle DEB. This angle is the same as its original because we're still subtending the same minor arc DB, and that arc hasn't changed size (since segment DB hasn't changed). So that's why it's valid to use the same x for the old angle DEB in black and the new angle DEB in red. They're the same angle.

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

Focus on triangle EBD. We have the following interior angles

For any triangle, the three interior angles must add to 180

B+D+E = 180

38+90+x = 180

128+x = 180

x = 180-128

x = 52

Angle DEB is 52 degrees

It's not a coincidence that we end up with the same angle as shown in the original diagram. The tangent-chord theorem says that the angle between a chord and tangent (as shown in the diagram) is exactly equal to the inscribed angle that subtends the arc formed by the chord. Arc DB is formed by chord DB.

In short, the tangent-chord theorem says that inscribed angle DEB and angle ABD are the same measure (both are 52 degrees).

This demonstration I've shown is one way to prove the tangent-chord theorem. Though a more rigorous proof would involve another variable.

Answer:

Step-by-step explanation:

Carry out indicated operations to see if they are equal

2(6-3x)+x=2(3x)+x+12

2(6)+2(-3x)+x=6x+x+12

12-6x+x=6x+x+12 combine like terms on both sides

12-5x=12+7x (we can see here they are unequal but we can continue) subtract 12 from both sides

-5x=7x divide both sides by x

-5=7

7 is not equal to -5 so the original expressions aren’t equivalent.

Answer:

x = 19

Step-by-step explanation:

(10x - 23) and (7x + 34) are vertically opposite angles and congruent, so

10x - 23 = 7x + 34 (subtract 7x from both sides )

3x - 23 = 34 ( add 23 to both sides )

3x = 57 ( divide both sides by 3 )

x = 19

Answer:

[tex]P(H <3) = 0.875[/tex]

Step-by-step explanation:

Given (Missing from the question):

[tex]\begin{array}{cc}{H}&{P(H)&0&0.125&1&0.375&2&0.375&3&0.125\end{array}[/tex]

And the required question is:

Determine the P(H < 3)

P(H <3) implies that: P(H = 0) or P(H = 1) or P(H = 2)

So, we have:

[tex]P(H <3) = P(H = 0) + P(H = 1) + P(H = 2)[/tex]

[tex]P(H <3) = 0.125 + 0.375 +0.375[/tex]

[tex]P(H <3) = 0.875[/tex]

Answer:

800

Step-by-step explanation:

100x216=27

21600 divided by 27=800

The total budget for this student film was 800$.

A percent is a quantity or ratio that, in mathematics, represents a portion of one hundred. A dimensionless relationship between two numbers can be represented in a variety of ways, such as through ratios, fractions, and decimals. The symbol "%" is frequently written after the number to indicate percentages. Additionally, you can indicate them by adding "percent" or "pct" after the number.

Given, A bunch of buddies was producing a school movie. Their whole budget was spent on props and equipment. Equipment cost $216, while props accounted for 73% of the whole budget. Hence,

Percent of their budget they spent on equipment = 100 - 73 = 27

Also given the money spent on budget = 216

Thus, 27 % of the total budget = 216

1 % of the total budget = 8

Total budget = 8 *100

Therefore, This student movie had an 800-dollar budget in total.
