Divide £48 in the following ratios.
a 2:1 b) 1:3

Answers

Answer:

a) £32 and £16

b) £12 and £36

Step-by-step explanation:

It is given that:

Amount to divide = £ 48

a) 2 : 1

Let,

x be the times of share.

2x + x = 48

3x = 48

Dividing both sides by 3

[tex]\frac{3x}{3}=\frac{48}{3}\\x=16[/tex]

Thus,

2x = 2(16) = £32

x = £16

b) 1 : 3

x+3x=48

4x=48

Dividing both sides by 4

[tex]\frac{4x}{4}=\frac{48}{4}\\x=12[/tex]

x = £12

3x = 3(12) = £36

Therefore,

a) £32 and £16

b) £12 and £36

Calculate the perimeter of the shape to the nearest whole number

Answers

Answer:

Option B

Step-by-step explanation:

Perimeter of the given figure = Sum of measures of all sides

                                                = AB + BC + CA

Since, AB = BC = 9 cm (Radii)

CA = Length of arc CA which is the quarter of the circumference of a circle with radius 9 cm

CA = [tex]\frac{1}{4}(\text{Circumference of the circle})[/tex]

      = [tex]\frac{1}{4}(2\pi r)[/tex]

      = [tex]\frac{1}{2}(\pi )(9)[/tex]

      = 14.14 cm

Now perimeter of the shape = 9 + 9 + 14.14

                                                = 32.14 cm

                                                ≈ 32 cm

Therefore, Option B will be the correct option.

Hey please help, I'm pretty sure it's C, but I'm not sure if it's a also

Answers

Answer:

It is only C

Step-by-step explanation:

The only answer for this is C

The correct option is option C i.e. "If the ratio of the arc length to r is 1, then the measure of θ is 1 radians".

What is Arc length?

The arc length is defined as the interspace between the two points along a section of a curve.

Here,  we know that,

angle = arc length / radius    ............(i)

If  arc length / radius = 1   ............(ii)

then from eq. (i) and (ii), we get

angle = 1

θ = 1

Thus, The correct option is option C i.e. "If the ratio of the arc length to r is 1, then the measure of θ is 1 radians".

At the beginning of summer, Mark has $200 in savings and Ryan has $350. The brothers have mowing jobs set up for the summer. Because Mark is older, he receives $20 for each mowing job and Ryan receives $15. The brothers’ parents pay for the fuel used to mow, so all of the money the brothers earn goes to savings.

Write two equations, one for Mark and one for Ryan, to represent the money in savings (s) based on the number of mowing jobs (j) Mark and Ryan do.
Determine the number of mowing jobs it takes for Mark to have the same amount in savings as Ryan does. Show your work.

Answers

Answer:

30 jobs

Step-by-step explanation:

Mark

Initial amount - $200Earning - $20*jSaving is: S = 20j + 200

Ryan

Initial amount - $350Earning - $15*jSaving is: S = 15j + 350

If they get same saving, then the equations will be equal:

20j + 200 = 15j + 35020j - 15j = 350 - 2005j = 150j = 150/5j = 30

The answer is 30 mowing jobs

which equation can be used to solve 3/5 divided by 7/10

Answers

Answer:

35/50

Step-by-step explanation:

Here we will show you how to calculate 3/5 divided by 7/10. We will give you the answer in fraction form and in decimal form.

Here is 3/5 divided by 7/10 displayed

3/5 ÷ 7/10

The numbers in 3/5 divided by 7/10 are labeled below:

3 = dividend numerator

5 = dividend denominator

7 = divisor numerator

10 = divisor denominator

To make it a fraction form answer, you multiply the dividend numerator by the divisor denominator to make a new numerator.

Furthermore, you multiply the dividend denominator by the divisor numerator to make a new denominator:

3 x 10/5 x 7 = 30/35

Thus, the answer to 3/5 divided by 7/10 in fraction form is:

30/50
