Area of triangle Question 4

The angle m∠UVW can be found using angle of circumference rule in geometry. Therefore, m∠UVW = 67°

An angle at the circumference of a circle is half the angle at the centre standing on the same arc.

In other words, the angle at the centre of a circle is twice the angle at the circumference.

Therefore,

m∠UVW = 134 / 2

m∠UVW = 67 degrees

Answer:

£15.10

x + 20

64 counters in the bag

Total money = £21.30

Step-by-step explanation:

20p = £0.20

50p = £0.50

100p = £1.00

Total value:

⇒ 8 × 20p + 5 × 50p + 11 × £1 = 8 × 20p + 5 × 50p + 11 × 100p

                                                = 160p + 250p + 1100p

                                                = 1510p

                                                = £15.10

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

20 more than x:   x + 20

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

If one quarter of the counters in a bag are yellow, and there are 16 yellow counters in the bag:

⇒ total number of counters in the bag = 16 × 4 = 64

Let x = number of 20p coins

Let y = number of 50p coins

Let z = number pf £1.00 coins

Given:

⇒ 0.20x = 2.80

⇒ x = 2.80 0.20

⇒ x = 14

Therefore, there are 14 twenty pence coins.

Given:

We have calculated that there are 14 twenty pence coins, therefore:

⇒ total number of coins = number of 20p × 3            

                                        = 14 × 3

                                        = 42

As the total number of coins is 42:

⇒ x + y + z = 42

⇒ 14 + y + z = 42

⇒ y + z = 42 - 14

⇒ y + z = 28

Therefore, the total number of 50p and £1 coins is 28.

Given:

⇒ y = z + 10

Substitute  y = z + 10  into y + z = 28 and solve for z:

⇒ (z + 10) + z = 28

⇒ 2z + 10 = 28

⇒ 2z = 18

⇒ z = 9

Therefore, there are 9 one pound coins

total number of coins:

⇒  x + y + z = 42

substituting the found values of x and z:

⇒  14 + y + 9 = 42

⇒  23 + y = 42

⇒  y = 19

Therefore, there are 19 fifty pence coins

20p coins = 14

50p coins = 19

£1 coins = 9

Therefore, total money:

= 14 × 20p + 19 × 50p + 9 × 100p

= 280p + 950p + 900p

= 2130p

= £21.30

Step-by-step explanation:

The 10.547 feet up the wall will the top of the ladder be if the 11-foot ladder is placed against the wall. The ladder is on ground level at an angle of 73.5° to the horizontal.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

Length of the ladder = 11 foot

The angle between ladder and horizontal = 73.5 degree

The height of the wall, the top of the ladder be(h):

From the sin ratio:

sin73.5 =  h/11

h = 11sin73.5 = 10.547 feet

Thus, the 10.547 feet up the wall will the top of the ladder be if the 11-foot ladder is placed against the wall. The ladder is on ground level at an angle of 73.5° to the horizontal.

Answer:

(5 × 4) - 13 = 7

Step-by-step explanation:

Given that,

→ n = 5

Let's solve the problem,

→ x = n × 4

→ x = 5 × 4

→ [ x = 20 ]

Then 13 less than the product will be,

→ x - 13

→ 20 - 13 = 7

Therefore, the solution is 7.

Answer:

  10,071 years

Step-by-step explanation:

If 'a' is the fraction remaining, it satisfies the equation ...

  a = (1/2)^(t/5750)

Solving for t, we get ...

  log(a) = log(1/2)×t/5750

  t = 5750×log(a)/log(1/2) ≈ -19,101.09×log(a) . . . years

__

If 70.3% is lost, then 1 -0.703 = 0.297 is the fraction remaining. The age is estimated to be ...

  -19,101.09×log(0.297) ≈ 10,071 . . . years

The bones were about 10,071 years old.

Since that is a right triangle, we can use pythagorean theorem.
