How could you use the product of 108 and 4 find the product of 324 and 4

Answers

324 is exactly three times 108. Thus, the product of 324 and 4 is exactly three times the product of 108 and 4.

What is product?

In mathematics, a product is the outcome of multiplying two or more numbers together.

The outcome of multiplication is a product, or a factor, which is an expression that specifies the objects (numbers or variables) to be multiplied.

For instance, the result of multiplying 2 and 5 together is 10, or the product. Math requires a lot of multiplication.

Explanation:

Since, 324 is exactly three times 108,

324 = 3 x 108.

Therefore,

324 x 4 = (3 x 108) x 4

324 x 4 = 3 x (108 x 4)

Solving,

108 x 4 = 432

therefore,

324 x 4 = 3 x 432

324 x 4 = 1296.

As, shown above we can use the product of 108 and 4 to find the product of 324 and 4.

Thus, you multiply the product of 108*4 by thee to get 324*4

Therefore, 324 is exactly three times 108. Thus, the product of 324 and 4 is exactly three times the product of 108 and 4.

Rob has 40 coins, all dimes and quarters, worth $7.60. How many dimes and how many quarters does he have?

Answers

The required Rob has 16 dimes and 24 quarters as he has a total of 40 coins.

What are equation models?

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
Let x be the number of dimes that Rob has, and y be the number of quarters.

We know that he has a total of 40 coins, so,

x + y = 40 ( 1)

We also know that the value of all his coins is $7.60. The value of x dimes is 10x cents, and the value of y quarters is 25y cents. So,

10x + 25y = 760 ( 2)

Now we can solve for x and y. Let's start by solving equation 1 for one of the variables:

x + y = 40

y = 40 - x

Substitute this expression for y into equation 2:

10x + 25y = 760

10x + 25(40-x) = 760

10x + 1000 - 25x = 760

-15x = -240

x = 16

So Rob has 16 dimes. We can use equation 1 to find the number of quarters:

x + y = 40

16 + y = 40

y = 24

So Rob has 24 quarters.

Therefore, Rob has 16 dimes and 24 quarters.

24 quarters and 16 dimes because 24*25=600 and 16*10=160 add them 2gether will be 760=$7.60

Figure PQR is an equilateral triangle with a semicircle added to its base.What is the perimeter of figure PQR? Use 3.14 to approximate pi.

Answers

Perimeter of the figure PQR is 91.42 cm.

What is Perimeter?

Perimeter of a straight sided figures or objects is the total length of it's boundary

Given figure PQR consists of an equilateral triangle and a semicircle.

Length of side of an equilateral triangle = 20 cm

Perimeter of equilateral triangle = sum of the length of three sides

Perimeter = 3 × 20 = 60 cm

Now circumference of a circle = 2πr, where r is the radius.

Here there is a semicircle, which is the half of the circle.

Circumference of semicircle = 2πr / 2 = πr

Here Diameter = 20 cm

Radius = 20 / 2 = 10 cm

Perimeter of semicircle = 10π = 31.42 cm

Total perimeter = 60 cm + 31.42 cm = 91.42 cm

Hence the total perimeter is 91.42 cm.

$7(m-12)=5m \n \n 7m - 84 = 5m \n \n -84 = 5m - 7m \n \n -84 = -2m \n \n (-84)/(-2) = m \n \n (84)/(2) = m \n \n 42 = m \n \n m = 42 \n \n Answer: \fbox {m = 42}$

7(m-12) = 5m

7m - 84 = 5m

2m - 84 = 0

2m = 84

m = 42
