the sum of two numbers is 49.Twice the smaller number is 97 less than 3 times the larger number.What are the numbers. help mee I

kondaur [170]

Answer:

smaller number is 10

larger number is 39

Step-by-step explanation:

a = small number

b = larger number

a + b = 49

2a = 3b - 97

substitute 49-a into second equation for b

2a = 3(49-a) - 97

2a = 147 - 3a - 97

5a = 50

a = 10

b = 39

What is the square root of 500

noname [10]

500 is not a perfect square number. Therefore, find the factors of 500 with the largest perfect square. In this case, 100 is the largest perfect square number in 500.
$500= \sqrt{500} ^2$

$\sqrt{500}=\sqrt{100*5}$

$\sqrt{500}=\sqrt{100}\sqrt{5}$

$\sqrt{500}=10\sqrt{5}$

If you are simply looking for the calculator result, you will get $22.36$

The monthly demand for a company’s sports caps varies directly as the amount spent on advertising and inversely as the square of

Amanda [17]

Answer: $\$16.432$

Step-by-step explanation:

Let be "y" the monthly demand for the company’s sports caps, "x" the amount in dollar spent on advertising and "z"the price ind dollars per cap.

The model for this situation is:

$y=\frac{kx}{z^2}$

Where "k" is the constant of proportionality.

Since $y=300$ when $z=15$ and $x=2,500$ , we can substitute values into $y=\frac{kx}{z^2}$ and solve for "k" to finds its value:

$300=\frac{k(2,500)}{15^2}\\\\\frac{(300)(15^2)}{2,500}=k\\\\k=27$

Then, in order to calculate what price yields a demand of 300 caps when advertising is increased to $3,000, we must substitute the following values into $y=\frac{kx}{z^2}$ :

$x=3,000\\\\y=300\\\\k=27$

Then:

$300=\frac{(27)(3,000)}{z^2}$

Solving for "z" we get:

$z^2=\frac{(27)(3,000)}{300}\\\\z=\sqrt{\frac{(27)(3,000)}{300}}\\\\z=16.432$

A box with a square base and top is made with a cardboard that costs 0.3 cents per cm² . The base is double layered for reinforc

stich3 [128]

Answer:

Length = 10 cm

Width = 10 cm

Height = 12 cm

Step-by-step explanation:

Cost of a cardboard with a square base and top = 0.3 cents per cm²

0.3 cents = $0.003 (0.3/100)

Total cost for material = $3.6

The volume of the box = $3.6/$0.003 = 1,200cm³

The formula for volume = length × width × height.

Since the base and top are square, the length and width must have equal sizes.

Let us assume that

length = 10cm

width = 10cm

these will give an area of 100cm².

Volume = length * width * height

= Area * height

= 10 * 10 * height

= 100cm² * height

Therefore, the height will be the volume divided by area

= 1,200cm³/100cm²

= 12cm

Volume = 10 * 10 * 12

= 1,200cm³
