A coin is tossed 50 times. It lands on heads 30 times. Based on this outcome, how many times is the coin expected to land on heads if tossed 200 times?

A. 60
B. 80
C. 100
D. 120

Answer:

B

Step-by-step explanation:

Since all the expressions are on a straight angle (equalling 180) combine the expressions to form on big expression that is equal to 180 and solve.

6x - 10 + 4x + 6 + 7x + 14 = 180

17x + 10 = 180

      - 10    -10

17x = 170

÷17    ÷17

x = 10

Hope this helps

Answer:

x = 48

Step-by-step explanation:

(x - 6)⁰ + ( 2x + 42)⁰ = 180⁰

x - 6⁰ + 2x + 42⁰ = 180⁰

x + 2x - 6⁰ + 42⁰ = 180⁰

3x + 36⁰ = 180⁰

3x + 36⁰ - 36⁰ = 180⁰ - 36⁰

3x = 144⁰

3x / 3 = 144⁰ / 3

x = 48

Hope this helps, thank you :) !!

Answer:

Step-by-step explanation:

All the angles in a triangle have to add up to 180 degrees.

#17.)

45+50=95

180-95=85

x=85

#18.)

This one is a little different. The furthest two angles are complimentary which means that they add up to 180 degrees (a straight line.) Once you find the missing angle to that one, you can do the same thing as you did in #17.

180-118=62.

25+62=87

180-87=93

x=93

#21.)

For this one a slightly larger equation is needed. Since we don't have a definite number for the bottom left angle, we have to use x+2 as our number. We first have to find the bottom right angle though.

180-108=72

x+x+2+72=180

2x+74=180

2x=106

x=53

Answer

#17=85

#19=93

#21=53

Answer:

12 bracelets.

Explanation:

If we assume Jackie made the same number of beaded bracelets each day, we can divide the total number of bracelets 96, by the amount of days it took to make all the bracelets, 8. This gives us  

  [tex]\frac{96}{8}[/tex]=12

We can check the answer by working backwards. Each day 12 bracelets were made. There were 8 days.  12 × 8 = 96 .  So for 8 days 12 bracelets were made giving Jackie 96 bracelets.

Solve 3x−y=6;y=x−4

Steps:

I will try to solve your system of equations.

y=x−4;3x−y=6

Step: Solvey=x−4for y:

Step: Substitutex−4foryin3x−y=6:

3x−y=6

3x−(x−4)=6

2x+4=6(Simplify both sides of the equation)

2x+4+−4=6+−4(Add -4 to both sides)

2x=2

(Divide both sides by 2)

x=1

Step: Substitute1forxiny=x−4:

Base x Height = Area

10x12=120 the area of the rectangle is 120

area of the triangle is 28

sorry but I don't know the trapezoid

The area of the rectangle is 120 cm².

The area of the triangle is 24 cm².

The area of the trapezoid is 144 cm².

An open, flat object with four straight sides and one pair of parallel sides is referred to as a trapezoid or trapezium.

A trapezium's non-parallel sides are referred to as the legs, while its parallel sides are referred to as the bases. The legs of a trapezium can also be parallel. The parallel sides may be vertical, horizontal, or angled.

The area of a trapezoid is (1/2)×(sum of the two parallel sides)×height.

We know, the area of a triangle is (1/2)×base×height and the area of a rectangle is (length×width).

Therefore, From the given information,

The area of the triangle is, (1/2)×4×12 = 24cm².

And the area of the rectangle is, (10×12) = 120 cm².

Therefore, The area of the trapezoid is,

= (24 + 120) cm².

= 144 cm².
