1 answer:

8 0

Answer:
a) 16: 24
b) £600 : £1400
c)  6 : 12 : 18

40 in the ratio 2 : 3

To split an amount based on ratio 2:3 , first, we need to find the total share.

-------------------------------------------------
Find total shares
-------------------------------------------------
2+3 = 5

Then we need to find the the amount of 1 share worth

-------------------------------------------------
Find 1 share
-------------------------------------------------
5 shares = 40   ← divide by 5 on both sides
÷ 5 ÷ 5
1 share = 8

Now that we know one share is 8, we need to find the amount according to the shares allocation, which is 2 and 3 in this question.

-------------------------------------------------
Find 2 shares
-------------------------------------------------
1 share = 8   ← multiply by 2 on both sides
x2 x2
2 shares = 16

-------------------------------------------------
Find 3 shares
-------------------------------------------------
1 share = 8
x3 x3
3 shares = 24

The ratio is 2 : 3. The 40 is therefore the amount split as 16:24

-------------------------------------------------
Answer: 16: 24
-------------------------------------------------

£2000 in the ratio 3: 7

To split the £2000 into the ratio 3:7, first, we need to find the total shares.

-------------------------------------------------
Find total shares
-------------------------------------------------
3 + 7 = 10

Then we find the 1 share worth
-------------------------------------------------
Find 1 share
-------------------------------------------------
10 shares = £2000   ← divide by 10 on both sides
÷10 ÷10
1 share = £200

Now that we know 1 share is worth £200, we need to find the shares according to the ratio allocation.

-------------------------------------------------
Find 3 shares
-------------------------------------------------
1 share = £200     ← multiply 3 on both sides
x3 x3
3 shares = £600

-------------------------------------------------
Find 7 shares
-------------------------------------------------
1 share = £200    ← multiply by 7 on both sides
x7 x7
7 shares = £1400

The ratio 3 : 7, the £2000 is spilt into £600 : £1400

-------------------------------------------------
Answer: £600 : £1400
------------------------------------------------

36 kg into the ratio 1:2:3

To spilt the 36kg, first we find the total number of shares

------------------------------------------------
Find total shares
------------------------------------------------
1 + 2 + 3 = 6

36 kg is split into 6 shares. We need to find the allocation of 1 share.
------------------------------------------------
Find 1 share
------------------------------------------------
6 shares = 36 ← divide by 6 on both sides
÷6 ÷6
1share = 6kg

The allocation of 1 share is 6kg. Now find 2 shares and 3 shares

------------------------------------------------
Find 2 shares
------------------------------------------------
1 share = 6kg ← multiply by2 on both sides
x2 x2
2 shares = 12kg

------------------------------------------------
Find 3 shares
------------------------------------------------
1 share = 6 kg ← multiply by 2 on both sides
x3 x3
3shares = 18kg

The ratio is 1:2:3. 36kg is spilt into 6: 12: 18

------------------------------------------------
Answer: 6 : 12 : 18
------------------------------------------------

Please help me i rlly need help

Mumz [18]

Answer:

Step-by-step explanation:

Given a line with points; (2, 5) (3, 8).

1. Find the slope of the given line

The formula for finding the slope is:

$\frac{y_{2}-y_{1} }{x_{2} - x_{1}}$

Substitute in the values;

$x_{1} = 2\\y_{1} = 5\\x_{2} = 3\\y_{2} = 8$

$\frac{8-5}{3-2}$

simplify;

$\frac{3}{1}$

= 3

2. Find the slope of the parallel line;

Remember, when two lines are parallel, they run alongside each other, of infinitely long, but they never touch. Hence two parallel lines have the same slope. Therefore, the slope of a line that is parallel to the given one will also have the same slope as the given one, which is 3.

the area of a rectangle is 42.15 square meters. if the length is 21 meters, what is perimeters of the rectangle?

Vsevolod [243]

Answer:

perimeters of the rectangle=p=46.014 metres

Step-by-step explanation:

Given that:

Length (l) = 21 m

Area of rectangle(A) = 42.15 meter-square

Width (w)=?

Required data:

Perimater of Rectangle=p=?

Calculation:

As we know that Area of rectangle=A=l*w

Putting the value we get

42.15 m(square)=(21 m)*w

or w=42.15/21

or w=2.007 m

Now to find perimters of rectangle we know that

p=2(l + w) metres

putting the values

p=2(21+2.007) metres

p=2(23.007) metres

p=46.014 metres
