Blank 1:

Answers

Answer:

[tex]\huge\boxed{Diameter=11cm}[/tex]

Step-by-step explanation:

Important information:

Circumference of a circle= [tex]\pi*diameter[/tex]

Method:

To work out the diameter, we would need to divide the circumference of 34.54 by pi, which in this case is 3.14, this gives us 11cm. This is because we are simply rearanging the formula of the circumference of a circle to make the diameter the subject.

Step By Step:

1) Rearange the formula to make the diameter the subject.

[tex]diameter=\frac{circumference}{\pi}[/tex]

2) Divide 34.54 by 3.14([tex]\pi[/tex]).

[tex]34.54/3.14=11cm[/tex]

Diameter

There is a a circle whose circumference is 34.54 cm. Find the diameter of the circle. Remember use 3.14 for π.

- To know the diameter divide 34.54 cm by pi (π) to get the answer.

[tex] \large \tt d = \frac{34.54}{\pi} \\ \large \tt d = 11cm[/tex]

Therefore, the diameter of the circle is 11cm

What is the measurement of angle A?

Answers

The answer should b 55 degrees

Answer:

∠A  = tan⁻¹ (35/12) ≅  71.075 ° or 1.24 radians

Step-by-step explanation:

Since this is a right angled triangle, then we can use basic trigonometry to solve for ∠A.

We have the measure of the  side opposite (35) and adjacent (12) to ∠A.

Since tan(x) = opp/adj

 then tan (∠A) = 35/12

              ∴ ∠A  = tan⁻¹ (35/12)     [by taking the tan⁻¹ of both sides of the eq]

                  ∠A ≅ 71.075 ° or 1.24 radians

Martin is building a rectangular fire pit in his backyard. He dug a hole 30 inches by 30 inches. He decides to make each side of the pit 6 inches longer.


What is the percent increase in the area of the fire pit?

Answers

Answer: 44%

Step-by-step explanation:

Area of the first hole = 30 × 30 = 900

Area of second hole = (30+6) × (30+6) = 36 × 36 = 1296

Percentage increase = (1296 - 900) / 900 × 100

= (396 / 900) × 100

= 44%

If a line passes through (6,4) and (12,7), what is the slope? I really need help and if you can please explain how you got the asnwer

Answers

Answer:

0.5 OR 1/2

Step-by-step explanation:

Since the two points are (6,4) and (12,7) you would find the distance in x and y.

Slope = change in y/ change in x

Change in y: the y coordinates are 4 and 7, so 4 + 3 = 7. +3 is the change.

Change in x: the x coordinates are 6 and 12, so 6 + 6 = 12. +6 is the change.

Slope = 3/6 = 1/2 = 0.5 = 50%

Answer:

x = 5 cm

Area = 56 cm²

Step-by-step explanation:

The perimeter of the triangle is given as : 21 cm

The two sides given are : 6 cm and 10 cm. The other side has a length of ;

21 - {6+10} = 21 - 16 = 5 cm

This means the value of x is 5 cm

The rectangle will now have its measurements as ;

Length = 7 cm

Width = x + 3 = 5+3 = 8 cm

The area of the rectangle will be :

A = l * w = 7 * 8 = 56 cm

An expression for the nth term of another sequence is 11 – n2 (i) Find the third term of this sequence.
(ii) Find the fifth term of this sequence.

Answers

Answer:

3rd term of this sequence = 2

5th term of the sequence = -14

Step-by-step explanation:

nth term = 11 - n²

(i) Find the third term of this sequence

When n = 3

nth term = 11 - n²

3rd term = 11 - 3²

= 11 - 9

= 2

3rd term of this sequence = 2

nth term = 11 - n²

Find the fifth term of this sequence.

When n = 5

5th term = 11 - 5²

= 11 - 25

= -14

5th term of the sequence = -14
