Answer:

35.0 cm (to 3 significant figures)

Step-by-step explanation:

Circumference of a circle = 2d (where d is the diameter).

Since the rectangle is inscribed in the circle (all 4 vertex touch, but not intersect, the circumference of the circle), we can see that the diameter of the circle is in fact the diagonal of the rectangle.

Therefore, to calculate the circumference we need to find the diagonal of the rectangle and plug it into the above formula.

To find the diagonal, we use Pythagoras' Theorem a² + b² = c²  (where a and b are the legs, and c is the hypotenuse of a right angled triangle).

From inspection, the diagram has given us the lengths of the legs as 9cm and 15cm.  So:  

 9² + 15² = c²

81 + 225 = c²

      306 = c²

             c = √306 = 3√34

Therefore, the diameter of the circle = 3√34 cm

Circumference = 2d

                         = 2 x 3√34

                         = 6√34

                         = 35.0 cm (to 3 significant figures)

Answer:

  A : B scale factor is 6 : 1

Step-by-step explanation:

Writing both given ratios in least-to-greatest order and in lowest terms, we have ...

  24 : 36 : 45 = 8 : 12 : 15 . . . triangle A

  4 : 6 : 7.5 = 8 : 12 : 15 . . . . . triangle B

The ratios of side lengths are the same, so the triangles are similar. The sides of the larger one are 24/4 = 6 times the sides of the smaller one.

  A : B scale factor is 6 : 1

The ratio of a:b in 8a + 3b = 5a + 7b is 4:3.

A ratio is an ordered pair of numbers a and b, written as a/b where b does not equal 0. A proportion is an equation in which two ratios are equal to each other. For example, if there are 2 boys and 6 girls, you can write the ratio as: 1 : 3 (for every boy there are 3 girls).

Ratios compare two numbers obtained by dividing. If one data point (A) is compared to another data point (B), it is expressed as A/B. It means that we are partitioning information A from information B. For example, if A is five and B is 10, your ratio would be 5/10, or 1/2.

For above information,

8a + 3b = 5a + 7b

8a-5a = 7b- 3b

3a= 4b

So, a/b= 4/3

a:b  is 4:3

Thus, the ratio of a:b in 8a + 3b = 5a + 7b is 4:3.

Step-by-step explanation:

solve simultaneously

subtract the 2 equations like you subtract pure numbers from each other.

5x + 2y = 12

3x + 2y = 8

5x - 3x +2y - 2y = 12 - 8

2x = 4

x = 2

alternatively...

3x + 2y = 8

5x + 2y = 12

-2x = -4

x = 2.

Answer:

-2/45

Step-by-step explanation:

-4/9 is simplified and both 4 and 9 are perfect squares.

-8/20 can be reduced to -2/5 since both 8 and 20 are divisible by 4.

The difference between them is given by -4/9 - (-2/5) = (18-20)/45 = -2/45.

Answer:

25 percent

Step-by-step explanation:

Since the dance team has 9 girls and 3 boys, it is made up of 12 people.  3 of those members are also on the debate team.  12/3 = 4, meaning that a fourth of the dance team is also on the debate team.  This translates to 25 percent

25% of the dance team is also on the debate team.

The percentage means the required value out of 100.

It is calculated by dividing the required value by the total value and multiplying by 100.

The percentage change is also calculated using the same method.

In percentage change we find the difference between the values given.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

There are a total of 9 + 3 = 12 members on the dance team.

Two of the girls and 1 of the boys are also on the debate team.

i.e

2 + 1 = 3

The percentage of the dance team that is also on the debate team.

= (3/12) x 100%

= 25%

Thus,

25% of the dance team is also on the debate team.

Answer:

1. 6.35

2. 750

Step-by-step explanation:

Answer:

We say one integer divides another if it does so evenly, that is with a remainder of zero (we sometimes say, "with no remainder," but that is not technically correct). More formally, mathematicians write: If a and b are integers (with a not zero), we say a divides b if there is an integer c such that b = ac.

A number divides another number of the quotient between the second and the first gives an integer number

We say that a number n divides another number m if, when we take the quotient between m and n, the outcome is an integer number.

So we should have that:

m/n = integer number.

This also means that a number only can divide another number if this second number is a multiple of the first one, so if we say that (for example).

m/n = 3

Then:

m = 3*n

So m is a multiple of n, which also means that n divides m.

Answer:

as it is a right angled triangle

we can find its 3rd side with the help of hypotenuse formula.

according to it

h² = a² + b²

here,

h = hypotenuse i.e. longest side of a right angled triangle

a = side

b = base

now,

a/q we have to find h (or hypotenuse) of the right angled triangle

h² = (12)² + (5)²

h = 144 + 25

h = 169

h² = √169 = 13

therefore, 3Rd side of the triangle is 13.
