A mother is three times as old as her daughter,in twelve years time she will be twice as old.How old is the mother now ?​

Answer:

64 cm^2

Step-by-step explanation:

The formula for volume of a cube is v = (side length)^3  or [tex]s^{3}[/tex] where s= side length.

To get the length of one side, you need to take the cube root of 512cm^3, which gives you side length = 8

The formula for area of a square is A=s^2 where s= side length.

Plug s=8 into the equation, so A = 8^2 = 64

The area of each side is 64 cm^2

Answer:

Using the Law of Diminishing Marginal Utility, Jane would not be better off buying one more fry, since the marginal utility she obtains from the fries are lower when compared to the chicken sandwich; therefore, she would be better off ordering another chicken sandwich

5a+(a+60)°+(2a+140)° = 360°

5a+a +60+ 2a+ 140 = 360

8a= 360-60-140

8a = 160 ( divide by a 8 on both sides)

a = 20°

Answer:

ok so we have to see how much work each noodle machine does so

15/5=3

so each does 3 of the 15 days of work

so if we take away 2 machines then it will take 25 days

Hope This Helps!!!

The required, 3 Machines to complete the production of noodles in 25 days.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
5 machines finish the work in 15 days,
1 machine finishes the work in 15 × 5 days,
Now,
3 machines finish the work in 15 × 5 / 3 = 25 days

Thus, the required, 3 Machines complete the production of noodles in 25 days.

Answer:

15+16+19+10=  60cm

Step-by-step explanation:

If you want to find the perimeter of a polygon, you need to add all the sides.

The required perimeter of the given polygon will be 60 cm.

The perimeter of a polygon is defined as the addition of the lengths of the polygon's all sides.

We have been given the polygon whose dimensions of the sides are 15 cm, 16 cm, 19 cm, and 10 cm​

We have to determine the perimeter of the given polygon.

As we know the perimeter of a polygon is the addition of the measurements of the polygon's all sides.

As per the given question, the required solution would be as:

the perimeter of the polygon = 15 cm + 16 cm + 19 cm + 10 cm​

Apply the addition operation, and we get

the perimeter of the polygon = 60 cm

Therefore, the perimeter of the given polygon will be 60 cm.

Adding the percentage to the selling price.

Sum the first 1000 natural numbers:

[tex]\displaystyle 1 + 2 + 3 + \cdots + 100 = \sum_{i=1}^{1000} i = \frac{1000 \cdot 1001}2 = 500,500[/tex]

Since 1000/5 = 200, there are 200 multiples of 5 in the range 1-1000. Sum them up:

[tex]\displaystyle 5 + 10 + 15 + \cdots + 1000 = 5 (1 + 2 + 3 + \cdots + 200) = 5\sum_{i=1}^{200}i = 5\cdot\frac{200\cdot201}2 = 100,500[/tex]

Then the sum we want is

[tex]\displaystyle 1 + 2 + 3 + 4 + 6 + 7 + 8 + 9 + 11 + \cdots + 999 = 500,500-100,500 = \boxed{400,000}[/tex]
